## Summary
7 improvements, 1 bug fix.
## Improvements
- `trigger init` now sets up your AI coding assistant as part of project
setup: pick the MCP server, the agent skills, or both, then scaffold
with the CLI or hand off to your assistant. Adds a new `getting-started`
agent skill that teaches assistants how to bootstrap Trigger.dev
(install the SDK, write `trigger.config.ts`, create a first task, run
`trigger dev`), so the AI-driven setup path works end to end. It ships
in the CLI alongside the existing skills, version-matched to your SDK.
([#3872](https://github.com/triggerdotdev/trigger.dev/pull/3872))
- `dev` and `deploy` now fail with a clear error when two tasks are
defined with the same id, including across different task types (e.g. a
scheduled task and a regular task sharing an id). Previously the second
definition silently overwrote the first, so one of the tasks would
vanish with no warning. Task ids are detected as duplicates during
indexing (naming each offending id and the files it was found in), and
the same rule is enforced server-side when the background worker is
registered.
([#3865](https://github.com/triggerdotdev/trigger.dev/pull/3865))
- `trigger skills` installs Trigger.dev agent skills into your coding
agent so it knows how to write tasks, schedules, realtime, and
chat.agent code. The skills ship with the CLI and are copied into each
tool's native skills directory (Claude Code, Cursor, GitHub Copilot, and
Codex / AGENTS.md), and `trigger dev` offers to install them on first
run. ([#3868](https://github.com/triggerdotdev/trigger.dev/pull/3868))
- Reliability fixes for `chat.agent`. A user message sent while the
agent is streaming is no longer delivered twice (which could run a
duplicate turn), input appends now carry an idempotency key so a retried
send can't duplicate a message, stopping a generation clears the
streaming state so a page reload doesn't replay the stopped turn, and
runs can now carry the full set of dashboard tags instead of being
silently truncated. `onTurnComplete` now fires on errored turns (with
the thrown error attached) and the failed turn's user message is
persisted so it isn't lost on the next run. Custom agents and manual
`chat.writeTurnComplete` callers now trim the output stream, sending a
custom action no longer leaves a second stream reader running, and a
long-lived `watch` subscription no longer grows its dedupe set without
bound. ([#3891](https://github.com/triggerdotdev/trigger.dev/pull/3891))
- Continuation chat boots no longer stall for around 10 seconds before
the first turn. The `session.in` resume cursor is now found with a
non-blocking records read instead of draining an SSE long-poll (which
always waited out its full 5 second inactivity window, twice per boot),
the boot reads run concurrently, and chat snapshots carry the cursor so
subsequent boots skip the scan entirely.
([#3907](https://github.com/triggerdotdev/trigger.dev/pull/3907))
- Record client-side dequeue API latency in the supervisor consumer pool
as a Prometheus histogram
(`queue_consumer_pool_dequeue_duration_seconds`, labelled by `outcome`:
success/empty/error).
([#3887](https://github.com/triggerdotdev/trigger.dev/pull/3887))
- Add `GetProjectEnvironmentsResponseBody` and `ProjectEnvironment`
schemas for the new `GET /api/v1/projects/{projectRef}/environments`
endpoint, which lists the parent environments (dev, staging, preview,
prod) a personal access token can access for a project. Dev is scoped to
the token owner and branch (preview child) environments are excluded.
([#3880](https://github.com/triggerdotdev/trigger.dev/pull/3880))
## Bug fixes
- Fix two `chat.createSession()` bugs: stopping a generation no longer
wedges the run (the turn loop raced a `totalUsage` promise that never
settles after a stop-abort), and continuation runs now wait for the next
message instead of invoking the model with an empty prompt.

- Reliability fixes for `chat.agent`. A user message sent while the
agent is streaming is no longer delivered twice (which could run a
duplicate turn), input appends now carry an idempotency key so a retried
send can't duplicate a message, stopping a generation clears the

the boot reads run concurrently, and chat snapshots carry the cursor so
subsequent boots skip the scan entirely.
([#3907](https://github.com/triggerdotdev/trigger.dev/pull/3907))
- Fix `chat.headStart` when `hydrateMessages` is registered. The warm
route's step-1 partial now reaches the agent's accumulator on the
hydrate path, so `onTurnComplete` carries the full first turn (the
head-start user message included), tool-call handovers resume from step
2 instead of re-running step 1, and the assistant `messageId` stays
stable across the handover.
([#3907](https://github.com/triggerdotdev/trigger.dev/pull/3907))
- Preserve reasoning parts across the `chat.headStart` handover.
Extended-thinking models' step-1 reasoning now lands in the durable
session history (and `onTurnComplete`) under the same assistant
`messageId`, with provider metadata intact so Anthropic thinking
signatures survive replays.
([#3907](https://github.com/triggerdotdev/trigger.dev/pull/3907))

## Summary
Two `chat.createSession()` bugs that break chats at its abstraction
level:
1. **Stopping a generation wedged the run forever.** `turn.complete()`
bare-awaited the AI SDK's `totalUsage` promise, which never settles
after a stop-abort. The run stayed stuck inside the stopped turn (trace
shows a permanently partial `ai.streamText` span and no further `waiting
for next message`), so the chat could never take another message. Fixed
with the same 2s `Promise.race` guard `chat.agent`'s turn loop already
uses.
2. **Continuation runs invoked the model with an empty prompt.** The
first turn only waited for a message on `preload` boots. A continuation
run (spawned after a cancel, crash, or version upgrade) arrives with the
boot payload stripped, so the loop ran a turn with zero messages and
errored with `AI_InvalidPromptError: messages must not be empty`.
Message-less continuation boots now wait for the next session input
("waiting for first message (continuation)"), and `turn.continuation` is
preserved across the wait so user code can seed stored history off it.
Both reproduced and verified end-to-end against a live environment (stop
followed by a next turn; cancel followed by a continuation turn with
seeded history), plus the existing unit suite.
## Summary
Two read-replica races on the session APIs could break chats whose first
activity lands inside the replication window (or any time the replica
lags):
1. A session's first `.in` append or `.out` subscribe could fail with a
404 for a session that exists on the writer, because the route resolved
the Session row on the replica only.
2. `ensureRunForSession` probed run liveness on the replica, so a probe
miss on a run triggered moments earlier was judged "run is dead" and a
second live run was spawned for the same session. Both runs then
consumed the same input stream, producing duplicated turns and doubled
responses (and doubled LLM cost).
## Fix
Liveness now re-probes the writer before declaring the current run dead
(the old code already fell back to the writer, but only to recover the
friendlyId, after the wrong verdict was made). Session resolution on the
append and subscribe/init routes goes through a new
`resolveSessionWithWriterFallback`, which stays replica-first on the hot
path and only touches the writer on a miss.
Reproduced and verified against a local streaming replica with an
artificial apply delay: pre-fix, a send immediately after session
creation reliably produced either the 404 or two executing runs with a
doubled response; post-fix, the same flow produces exactly one run and
one response.
Also rides along: the local docker replica's default apply delay drops
from 150ms to a realistic 20ms (override via `REPLICA_APPLY_DELAY` when
you want to deliberately widen the race window).
`@trigger.dev/plugins` re-exported
`sanitizeBranchName`/`isValidGitBranchName` from `@trigger.dev/core` as
a convenience forwarder. Nothing actually imports them through this
package — every consumer (webapp, `@trigger.dev/rbac`, …) imports them
directly from `@trigger.dev/core/v3/utils/gitBranch`.
Removing the forwarder keeps the package entry free of **runtime** core
imports (only type re-exports + `buildJwtAbility` remain), so consumers
that bundle `@trigger.dev/plugins` from source don't pull an unrelated
core subpath into their build.
No behavior change; the helpers remain available from
`@trigger.dev/core` where they're defined.
## Problem
The item-streaming endpoint of the two-phase batch API (`POST
/api/v3/batches/:batchId/items`) processed streamed items strictly
sequentially. For a batch of many large payloads, each offloaded to
object storage inline, this serialized N object-store round-trips inside
a single request and could exceed Node's default `server.requestTimeout`
(300s). The webapp then returned `408`, which the SDK reads as `408
terminated` and retries up to 5 times, turning a slow ingest into a
failure that takes tens of minutes to surface.
## Fix
Ingest now runs through `p-map` over the NDJSON async iterable with
bounded concurrency (`STREAMING_BATCH_INGEST_CONCURRENCY`, default 10):
- `p-map` pulls lazily from the stream, so at most `concurrency` items
are read and in-flight at once. Peak memory stays bounded to roughly
`concurrency × STREAMING_BATCH_ITEM_MAXIMUM_SIZE` and request-body
backpressure is preserved.
- Set the env to `1` for fully sequential ingestion (escape hatch).
## Why this is safe (ordering and idempotency unchanged)
- Ordering derives from each item's index (enqueue `timestamp =
batch.createdAt + index`), not enqueue order.
- Dedup is atomic per index in `enqueueBatchItem`.
- The NDJSON parser now stamps oversized-item markers with their emit
position, removing the consumer's sequential `lastIndex` assumption (the
only order-dependent bit).
- The count-check and conditional-seal path is untouched.
## Scope
This speeds up every batch ingested through the streaming endpoint, not
just large-payload batches. Each item does a per-item Redis enqueue
regardless of size, and those now overlap. Large payloads benefit most
because they add an object-store offload round-trip on top of the
enqueue.
## Verification
Added an integration test (`streamBatchItems.test.ts`) that drives the
real service against Postgres + Redis + RunEngine and times a 150-item
batch at increasing concurrency. Object-store offload is modelled as a
fixed per-item latency (local round-trips are too small to compare
meaningfully):
```
runCount=150
large payloads (10ms/item offload):
concurrency=1 1739ms
concurrency=10 192ms (9.1x faster)
concurrency=50 57ms (30.7x faster)
small payloads (Redis enqueue only, no offload):
concurrency=1 90ms
concurrency=10 24ms (3.7x faster)
```
The test asserts correctness at every concurrency (all items accepted,
sealed, enqueued exactly once), that parallel ingest beats the
sequential floor, and that the small-payload case is strictly faster
than sequential, so the win is not specific to large payloads.
Also exercised end-to-end over real HTTP against a local server: a
20-item batch (12MB body) ingests and seals, a re-stream of the sealed
batch returns `sealed: true` with zero re-accepted items (idempotent
retry), and an oversized item still seals at its correct index.
Existing coverage stays green: concurrent ingest of a 100-item batch,
in-flight processing never exceeding the configured concurrency,
concurrent dedup on streaming retry, and emit-position marker indexing.
## Follow-ups (not in this PR)
- SDK pre-offload of large item payloads (send `application/store` refs
instead of raw blobs) to remove object-store work from the request hot
path and shrink the request body.
- Optional `server.requestTimeout` bump as a safety net.
## CI fix
Added `.github/workflows/codeql.yml` to replace GitHub's automatic
("dynamic") CodeQL scanning. The dynamic setup was failing to upload
SARIF results because the auto-generated `GITHUB_TOKEN` lacked the
`security-events: write` permission. The explicit workflow grants that
permission at the job level and pins all actions to commit SHAs,
consistent with the repo's security conventions.

guide](https://github.com/triggerdotdev/trigger.dev/blob/main/CONTRIBUTING.md)
- [ ] The PR title follows the convention.
- [ ] I ran and tested the code works
---
## Testing
- Integration test (`streamBatchItems.test.ts`) validates correctness
and performance at concurrency 1, 10, and 50 for both large and small
payloads.
- End-to-end verified over real HTTP: 20-item/12MB batch ingests and
seals, idempotent retry returns `sealed: true`, oversized item seals at
correct index.
---
## Changelog
Streaming batch ingest now processes items with bounded concurrency
instead of one at a time, so batches of many large payloads ingest far
faster and no longer time out. Concurrency is configurable via
`STREAMING_BATCH_INGEST_CONCURRENCY` (default 10); set it to 1 for fully
sequential ingestion.

## What
`buildJwtAbility` — the decoder for public-token scope strings
(`read:tags:…`, `read:runs:run_abc`, `admin`, …) — now lives in
`@trigger.dev/plugins` as the single source of truth.
`@trigger.dev/rbac` re-exports it, so the built-in fallback and any auth
plugin interpret a token identically.
Scope strings are split on only the first **two** colons
(`action:type:id`), so a resource id that itself contains colons — e.g.
a tag like `user:123` — is matched in full rather than truncated to its
first segment. (The fallback already did this; this makes it the one
shared implementation.)
`@trigger.dev/plugins` is now **private (unpublished)** and gains a
`@triggerdotdev/source` export condition, so consumers bundle it from
source per-commit like `@trigger.dev/core` instead of resolving a
published version — no cross-version coordination.
## Why
Two hand-maintained copies of the scope grammar drift, and the
difference silently changes what a token grants. One shared decoder
removes that class of bug.
## Notes
- No changeset: `@trigger.dev/plugins` is now private and
`@trigger.dev/rbac` is internal — neither is published.
- Unit coverage for the colon-id path lives in
`internal-packages/rbac/src/ability.test.ts` (now exercising the shared
function).
## Summary
When the realtime runs feed (the backend behind the `realtimeBackend`
feature flag) hydrates a change from a Postgres read replica, the read
can race the replica's apply of the very write that triggered it. The
delivered row then carries the previous change's content, and an
isolated final change (for example a last `metadata.set` before a run
goes quiet) is not corrected until the roughly 20 second backstop poll.
Measured against a replica with deliberate apply delay, every delivery
trailed exactly one change behind and a final change stranded for the
full backstop interval.
## Fix
Publishers stamp each change record with the committed row's
`updatedAt`, taken from writes they already perform, so the stamp costs
no extra queries. The router delays its wake hydrate until the replica's
measured lag has passed, anchored to that timestamp: a record that has
already spent longer than the lag in transit is hydrated immediately, so
only the racing leading edge ever waits. After hydrating, a tripwire
compares each row against its record's watermark. Still-stale rows are
withheld and retried briefly, and each detection feeds the lag estimate.
If retries run out, the rows are delivered anyway (liveness over
freshness) and follow-up re-hydrates emit the fresh version through the
normal working-set diff once the replica catches up, with the backstop
as the terminal net.
Replica lag is sampled reader-side only, and only while feeds are
active. Aurora reports live lag via `aurora_replica_status()`; vanilla
Postgres can only report "caught up or not" (mid-apply lag is not
honestly measurable from a replica), so tripwire observations floor the
estimate there. Deployments without a replica resolve to zero lag and
skip the gate entirely. Tunables live under
`REALTIME_BACKEND_NATIVE_REPLICA_LAG_*`, and
`realtime_native.stale_hydrates` plus
`realtime_native.replica_lag_estimate_ms` make replica health
observable.
Two adjacent fixes: a metadata update that writes nothing no longer
publishes a change record, and buffered parent and root metadata
operations now publish when the flusher writes them, so those changes
wake live feeds instead of waiting for the backstop.
For local testing, `docker-compose` gains an opt-in `database-replica`
service (compose profile `replica`) with a configurable
`recovery_min_apply_delay`, which reproduces replica-lag behavior
deterministically. With the gate disabled this rig reproduces the
one-change-behind delivery exactly; with it enabled, deliveries arrive
with current content at roughly the true replica lag, across write rates
faster and slower than the lag itself.
## Summary
The environment variables page loaded every variable value in the
project, unfiltered by environment. Archiving a preview branch does not
delete its environment variable value rows, so projects that churn
preview branches accumulate values forever, and every page view loaded
all of them. On large projects this made the page loader take many
seconds and stalled the server while deserializing the oversized result.
## Fix
The presenter now loads the displayed environments first and filters the
`values` relation to those environment IDs. That matches the display
semantics exactly (per-user dev environments and active branch
environments included), and the lookup is covered by the existing unique
index on `(variableId, environmentId)`. Values in archived branch
environments are no longer fetched at all.
Covered by a new testcontainers test asserting that values from active
environments (including branch environments) are returned while archived
branch environments are excluded.
## Summary
`test/runsRepositoryCursor.test.ts` pinned its fixture runs to
`createdAt = 2026-06-04T16:55:07Z`. `listRuns` applies the default 7 day
window when no time filter is given, so the fixtures aged out of the
window at 16:55 UTC on 2026-06-11 and all five tests started failing for
every branch, regardless of what the branch changed. The tests were
green on their own CI two days earlier because the fixtures were only
five days old at the time.
This switches the fixture base to a relative timestamp (one hour ago),
so the fixtures stay inside the default window permanently. Verified the
suite goes 5/5 green with this change on the same environment where the
pinned dates fail 5/5.
## Summary
The run trace page loader serialized every span's raw OTel events (with
full properties) into the response, even though the tree UI only renders
the derived `timelineEvents` and the span detail panel refetches what it
needs. On event-heavy traces that inflated both the loader payload and
the server-side heap copies built per request. This PR keeps raw span
events server-side and pairs that with a few related trace-view
improvements:
- A new optional `TRACE_VIEW_EMERGENCY_SPAN_CAP` env var (unset by
default) clamps the trace summary and detailed trace summary span limits
on both event store paths, including the public run trace endpoint, so
operators can bound trace query sizes in one place without retuning the
per-store limits.
- The TreeView virtualizer resolved every rendered row with a linear
scan over the whole tree (and `getNodeProps` did the same via
`findIndex`); rows now resolve through memoized id lookup maps, which
matters once traces reach tens of thousands of spans.
- The run stream SSE lookup now applies the same organization membership
scoping as the rest of the run page presenters, for consistency.
Behavior is unchanged by default: the trace tree renders from the same
`timelineEvents` it always has, and the new cap only takes effect when
set.
## Summary
Three related fixes for `chat.headStart` and continuation boots, found
while investigating customer reports.
**1. `chat.headStart` now works with `hydrateMessages`.** The turn-0
handover splice only ran on the default accumulation path, so agents
registering `hydrateMessages` silently lost the warm route's step-1
response: pure-text turns fired `onTurnComplete` with no assistant
message (and an empty durable write), tool-call turns re-ran step 1 from
scratch under a fresh `messageId`, and the head-start user message never
reached the hydrate hook at all. The first-turn history now reaches
`hydrateMessages` as `incomingMessages`, and the splice runs after both
accumulation branches, deduplicated by the handover `messageId`.
**2. Reasoning parts survive the handover.** The synthesized partial
only mapped text and tool-call parts, so an extended-thinking model's
step-1 reasoning streamed to the browser but never reached durable
history. Reasoning parts now map through with provider metadata, so
Anthropic thinking signatures survive a UIMessage round trip on hydrate
replays.
**3. Continuation boots no longer stall for ~10 seconds.** The `.in`
resume cursor was found by draining an SSE subscription that only closes
after its 5 second inactivity window, and the scan ran twice per boot.
It is now a non-blocking records read of the latest turn-complete
header, runs at most once per boot, the boot reads run concurrently, and
chat snapshots carry the cursor so subsequent boots skip the scan
entirely. Measured locally on a cancel-then-continue repro: pre-turn
continuation latency dropped from ~11s to ~0.5s.
Every fix was verified red-green: new unit tests reproduced each failure
before the fix, and end-to-end smoke tests against a live local stack
covered both handover legs, reasoning persistence with extended thinking
(including a follow-up turn that round-trips the persisted signed
reasoning back to the provider), and the boot timing comparison.
## Rollout
SDK-only; no server change required. A new SDK against a server that
does not serialize record headers degrades to the existing no-cursor
fallback. Old SDKs ignore the new snapshot field, and new SDKs fall back
to the records scan on snapshots written before it existed.
## Summary
HIPAA BAA is offered as a paid add-on on every paid plan. Each paid tier
on the in-app pricing card now has a "HIPAA BAA add-on" row with a
"Request a BAA" link that opens the existing contact dialog pre-filled
with a new `hipaa` inquiry type, prompting the user for their company
name and a brief description of the PHI workload.
The contact form's `feedbackTypes` are restructured to match the
marketing /contact form: every inquiry type carries a Plain label ID and
a "Contact form: ..." thread title, so threads land in Plain identically
whether they come from the dashboard or the marketing site. The
included-compute line on each tier also picks up the credits wording
from the marketing pricing page, and the Enterprise tier lifts its title
above the features row.
The compute suspend flow delays snapshots by `snapshotDelayMs` (~30s) so
short-lived waitpoints skip the snapshot entirely, with the intent that
a run continuing before the delay expires cancels the pending snapshot.
But the only `cancel()` call site was the `/continue` action, which
runners only invoke when restoring from an already-taken snapshot — so
pending snapshots were never cancelled (zero `snapshot.canceled` events
ever emitted in prod). When a run resumed and completed inside the
window, the stale snapshot fired ~30s later anyway, pausing the VM 6–13s
mid warm-start long-poll; the frozen guest couldn't fire its abort timer
or send a FIN, causing stalls and run-engine driven retries.
### Change
- Cancel the pending snapshot on `attempt.complete` — after the platform
accepts the completion, before the HTTP reply (so it can't reorder with
the runner's next `/suspend`).
- Cancel on `runDisconnected` (crash, exit, or run replaced on the
socket).
- Both cancels are guarded by a runnerId match (new
`TimerWheel.peek()`): a stale duplicate runner for a reassigned run must
not cancel the fresh runner's pending snapshot. A missing runnerId falls
through to an unconditional cancel (the pre-existing `/continue`
behavior is unchanged).
Waitpoint suspensions keep the runner socket connected and the attempt
incomplete, so neither hook touches a snapshot that is still wanted.
Known limitation (fail-safe direction): `socket.data.runnerId` is frozen
at the websocket handshake, so after a same-supervisor restore the
disconnect-path guard refuses the cancel. The `attempt.complete` path
uses the runner's current header id and is unaffected.
`ComputeWorkloadManager.create` swallows gateway errors currently, so a
cold start that fails placement (e.g. a netns slot with a busy tap, a
full node disk) silently abandons the dequeued run until the run
engine's `PENDING_EXECUTING` heartbeat timeout redrives it via stall
detection.
### Changes
- Retry `instances.create` with short backoff (default 3 attempts, 250ms
backoff), recording `createAttempts` in the wide event.
- **Only statuses where the create definitely did not commit are
retried**: 500 (agent/fcrun create failed) and 503 (no placement).
502/504 are excluded — the gateway emits those when it fails to reach
the node or read its response, which can happen *after* the agent
committed the create; the gateway only records the instance name on a
clean 201, so a same-name retry would miss the collision check and could
double-create the VM on another node. Network-level fetch failures are
retried (if the gateway processed the create, its name index is
populated and the retry 409s harmlessly). Timeouts are not retried.
- **Retry attempts after a 5xx use a deterministic `-rN` name suffix**:
a failed create can leave its name registered until async cleanup runs.
Attempt 1 keeps the unsuffixed name.
Fixes an intermittent `Test timed out in 30000ms` in the
`streamBatchItems` suite. Not a logic hang — the 30s budget covers
container setup, and each case boots its own per-test Redis container +
a full `RunEngine`, so under CI Docker contention a cold boot can cross
30s (which is why the failure moved between tests).
- New `containerTestWithIsolatedRedisNoClickhouse` fixture (Postgres
clone + per-test Redis, no ClickHouse) — this suite never uses
ClickHouse, but the old fixture's auto `resetClickhouse` forced a
ClickHouse boot + migration onto the cold-start test.
- Raised `testTimeout` 30s → 120s, matching the run-engine convention
for this footprint.
## Summary
A batch of reliability fixes for `chat.agent`:
- A user message sent while the agent is streaming is no longer
delivered twice (which could run a duplicate turn).
- Input appends carry an idempotency key (`X-Part-Id`) so a retried send
can't duplicate a message.
- `onTurnComplete` now fires on errored turns with the thrown error
attached, and the failed turn's user message is persisted so it isn't
lost on the next run.
- Stopping a generation clears the streaming state, so a page reload
doesn't replay the stopped turn.
- Custom agents and manual `chat.writeTurnComplete` callers trim the
output stream, sending a custom action no longer leaves a second stream
reader running, a long-lived `watch` subscription no longer grows its
dedupe set without bound, promoting a queued message to steering no
longer risks a double-send, and runs keep the full set of dashboard
tags.
The `X-Part-Id` header is accepted by current servers (they just don't
dedupe on it yet), so this is safe to ship ahead of the matching server
change.
## Summary
Reliability and authorization fixes for realtime chat sessions:
- Session-stream waitpoint delivery is scoped to the environment, so two
environments using the same session `externalId` can no longer complete
each other's waitpoints.
- The session snapshot-url routes now enforce per-session authorization,
and appending to a session's `out` channel requires secret-key auth, so
a session-scoped token can't read another session's snapshot or forge
assistant output.
- Appends that carry an `X-Part-Id` header are deduplicated on retry, so
a retried send can't duplicate a message.
- Session creation rejects expired sessions (instead of triggering a run
that can never receive input), `externalId` is immutable after creation,
and the sessions list endpoint returns friendly `run_*` ids to match the
single-session routes.
## Rollout
The waitpoint cache key gains an environment prefix. To keep waitpoints
registered by the previous deploy working across the boundary, the drain
reads both the new and the previous key for this release; the legacy
read can be removed a release later once no pre-deploy waitpoints
remain.
## Summary
Adds a second backend for the realtime runs feed (`useRealtimeRun`,
`subscribeToRunsWithTag`, `subscribeToBatch`), built to stay healthy
when a single busy environment has many subscribers watching many runs
at once. It is gated behind a feature flag with the existing backend as
the default, so nothing changes for users until it is enabled per
environment.
## Design
A run change is published once, as a small self-describing record, to a
single per-environment channel. Every feed is then a predicate over that
one stream rather than owning a channel:
- A per-instance router indexes the currently-held feeds by run, tag,
and batch. When a run changes it hydrates the affected rows once and
serializes them once, then fans the result to every matching feed. One
hot shared tag watched by many subscribers costs a single database query
and serialize, not one per subscriber.
- Feeds that don't match a change are never woken, wake delivery per
environment is coalesced on a leading edge (250ms default) so a burst of
changes costs one wake, and cold reads coalesce onto a single
short-TTL-cached resolve.
- An admission gate bounds how many cold ClickHouse resolves run
concurrently, so a mass reconnect across many distinct filters queues
instead of stampeding the database.
- Changes that land while a client is between long-polls are delivered
on its next poll instead of waiting for the periodic backstop: each
environment buffers its recent change records, subscriptions linger
briefly after the last feed closes, and a newly-armed poll replays
exactly the connection's gap.
- The per-connection replay cursors behind that are shared across
instances via Redis (a single timestamp each), so a poll landing on a
different instance behind the load balancer still reads the connection's
true gap instead of falling back to a cold resolve. Cursor reads have a
bounded deadline and degrade to the cold-read path on any Redis trouble.
- Tag subscriptions with multiple tags match runs carrying all of the
tags, mirroring the existing backend's filter semantics, and live
long-polls hold for about 20 seconds to match its cadence.
- The per-environment channel supports Redis Cluster sharded pub/sub, so
the wake path scales horizontally across shards by environment.
- The backend reports its health through OpenTelemetry metrics (delivery
lag, poll resolution paths, backstop outcomes, replay and cursor-store
activity), with a provisioned Grafana dashboard for local development.
Everything is behind the feature flag and tunable via env vars; the
existing backend remains the default.
## Summary
When `RUN_ENGINE_READ_REPLICA_SNAPSHOTS_SINCE_ENABLED` is on,
`RunEngine.getSnapshotsSince` reads from the read replica. During write
spikes the replica can briefly lag, so the snapshot id a runner just
learned from the writer isn't visible there yet: the lookup threw, the
worker route returned a 500, and the runner waited for its next poll —
turning sub-second snapshot notifications into poll-interval latency
exactly when things are busiest. This PR makes the flag safe to enable:
a replica miss of the since snapshot gets one jittered retry on the
replica (most lag windows are shorter than the ~50–200ms wait, so the
writer is never touched), then falls back to the primary, observed via a
new `run_engine.snapshots_since.replica_miss` counter with an `outcome`
attribute (`replica_retry` vs `primary`). Only genuine misses — absent
on the primary too — remain errors.
## Design
- `getExecutionSnapshotsSince` now throws a typed
`ExecutionSnapshotNotFoundError` so the engine can distinguish the
expected lag miss from real failures. The message string is unchanged
and the error never leaves the engine.
- The recovery path only engages when the flag is on, a distinct replica
client is configured, and no transaction client was passed. With the
flag off, the path is behaviorally identical to before.
- Retry delay bounds are configurable
(`RUN_ENGINE_SNAPSHOTS_SINCE_REPLICA_RETRY_MIN_MS`/`MAX_MS`, default
50/200; `MAX_MS=0` skips the replica retry and goes straight to the
primary).
- The warn log fires only when the primary serves the read (the writer
spill is the operationally interesting event); replica-retry recoveries
are counted but quiet. A permanently-missing snapshot id stays an
error-level failure with a `failedDuring` field, so lag metrics aren't
polluted by bogus ids.
- Stale-tail lag (replica has the since snapshot but not newer rows)
deliberately still returns the replica's view; the next poll catches up.
- The since-snapshot anchor lookup is now scoped to the polled run
(`where: { id, runId }`), so a snapshot id from a different run raises
not-found instead of silently anchoring a too-wide window of the run's
snapshots.
## Test plan
All vitest + testcontainers, no mocks. A new `schemaOnlyPrisma` fixture
(migrated-but-empty clone database) simulates a replica that hasn't
caught up, and a real in-memory OTel meter pins the counter semantics
per outcome.
- [x] Replica catches up during the jittered retry window → served by
the replica, `outcome=replica_retry` = 1, primary never consulted
- [x] Replica permanently missing the since snapshot → served by the
primary, `outcome=primary` = 1
- [x] Snapshot missing on both replica and primary → null, counter = 0
- [x] Replica has the since snapshot but lags by one → the replica's
view is served, no fallback (verified discriminating power: the test
fails if reads secretly hit the primary)
- [x] Flag off with a replica configured → primary serves the read
- [x] Transaction client provided → bypasses the replica entirely
- [x] Since snapshot belonging to a different run → null
- [x] Existing getSnapshotsSince + waitpoints suites green; run-engine,
testcontainers, and webapp typechecks pass

The supervisor's dequeue round-trip time (`POST
/engine/v1/worker-actions/dequeue`) was measured but only flowed into
wide events and OTel span attributes — there was no Prometheus series,
so latency percentiles and error rates weren't queryable. This adds
`queue_consumer_pool_dequeue_duration_seconds` (histogram, label
`outcome=success|empty|error`) to the existing consumer-pool metrics,
scraped automatically by the existing ServiceMonitors on
queue-raider/schedule-raider/supervisor.
- Records every dequeue call, including failed ones, which previously
emitted no timing at all
- The pool's shared `ConsumerPoolMetrics` instance is injected into each
consumer (mirrors the `BackpressureMetrics` → `BackpressureMonitor`
wiring)
- Buckets extend to 30s because `wrapZodFetch` retries internally (5
attempts, ≥7.5s backoff before a retryable error surfaces)
- Existing `dequeueResponseMs` wide-event/span behavior unchanged
The `dispatch-main-image` job was hard-gated to
`triggerdotdev/trigger.dev` on the `main` ref. This makes it
configurable via repository variables, all defaulting to the current
values:
- `MAIN_IMAGE_DISPATCH_REPO` — the repo allowed to dispatch (default
`triggerdotdev/trigger.dev`).
- `MAIN_IMAGE_DISPATCH_REF_PREFIX` — the ref-name prefix that
dispatches, matched with `startsWith(github.ref_name, …)` (default
`main`).
- `MAIN_IMAGE_DISPATCH_TARGET` — the `repository_dispatch` target
(default `triggerdotdev/cloud`).
The job is additionally gated on `github.event_name == 'push'`. This is
necessary, not just defensive: the gate now keys off `github.ref_name`
rather than the computed image tag, and `ref_name` is still `main` when
`release.yml` invokes this workflow via `workflow_call` during a release
— so without the event guard the job would fire during every release and
fail on the absent `CROSS_REPO_PAT`. A version-equality check can't
replace it because `build-*` tags strip the prefix to the version
output.
Behaviour note: the intended dispatch paths — push to `main`, and push
of a `<prefix>*` tag in a downstream repo — are `push` events and are
unchanged. The one case that no longer dispatches is a manual
`workflow_dispatch` run of `publish.yml` on `main` (it previously did,
via the old `version == 'main'` check). That path is indistinguishable
from a manual release by event name, so `push`-only is the clean
discriminator.
Dispatching still requires `CROSS_REPO_PAT`, so setting the variables
alone doesn't enable anything.

## Summary
Adds `GET /api/v1/projects/{projectRef}/environments` (personal access
token auth), which lists the base environments a user can access for a
project — their own dev environment plus the project's staging, preview,
and production environments.
## Details
- Built on the PAT route builder, so it inherits org-membership auth and
the per-resource ability check.
- `dev` is scoped to the token owner; archived environments are
excluded.
- Returns the branchable **parent** preview environment — preview branch
children are not included. A consumer targets the parent; branch-level
overrides are handled separately.
- Sorted to match the dashboard's environment switcher (dev → staging →
preview → prod), and never returns API keys.
Example response:
```json
[
{ "id": "...", "slug": "dev", "type": "DEVELOPMENT", "isBranchableEnvironment": false, "branchName": null, "paused": false },
{ "id": "...", "slug": "stg", "type": "STAGING", "isBranchableEnvironment": false, "branchName": null, "paused": false },
{ "id": "...", "slug": "preview", "type": "PREVIEW", "isBranchableEnvironment": true, "branchName": null, "paused": false },
{ "id": "...", "slug": "prod", "type": "PRODUCTION", "isBranchableEnvironment": false, "branchName": null, "paused": false }
]
```
## Summary
The dashboard's Agent view rendered `source-url` and `file` message
parts by putting their `url` straight into an `href`/`src`. Those URLs
come from streamed agent and tool data, so a tool that emitted something
like `javascript:alert(1)` produced a clickable XSS payload in the
dashboard.
## Fix
A `toSafeUrl` helper now gates every URL before it reaches an
`href`/`src`: it allows only `http:`/`https:`/`blob:` (and
`data:image/...` for inline images) and returns `null` for anything
else. Unsafe values render as plain text instead of a link or image, so
a hostile or malformed URL degrades gracefully rather than becoming
clickable. Safe URLs render exactly as before. Covered by a unit test
over the allow/deny list.
## Summary
During `trigger()` worker-queue resolution, `getWorkerQueue` wrapped any
error from `getDefaultWorkerGroupForProject` into a client-facing
`ServiceValidationError` (HTTP 422) carrying `error.message`. That
method runs `project.findFirst` on the **writer**; when the writer is
unreachable Prisma throws a connection error (P1001) whose message
includes the database host, and that raw message was returned to the API
client and surfaced in the run view via the SDK's `TriggerApiError`.
It also mis-classifies a transient outage: a 422 is not retried by the
SDK, so triggers failed permanently instead of riding out a brief writer
blip.
## Design
This is the only place on the trigger path that folds a *caught* error's
message into a client-facing error — every other DB failure on the path
propagates to the route's generic 500 handler (scrubbed, and retried by
the SDK). So the fix is local:
- Add `isInfrastructureError()` — true for Prisma connection-level
failures (the DB-unreachable family: P1001/P1002/P1008/P1017, plus the
init/panic/unknown client error classes), false for query/validation
errors (e.g. P2002).
- At the wrap site, rethrow infrastructure errors so they reach the
generic 500 handler (no raw message, and retryable). Genuine domain
failures (e.g. "Project not found.") still become a 422.
Only P1001 ("can't reach database server") has been observed in
practice; the rest of the connection family is included as same-class
forward-proofing.
## Test plan
- [x] Unit: `isInfrastructureError` classifies a P1001 (incl. the Prisma
6.x `PrismaClientKnownRequestError` shape) and init errors as
infrastructure; P2002 and a plain `Error` as not
- [x] `getWorkerQueue` rethrows a P1001 unchanged instead of wrapping it
in a `ServiceValidationError`; still wraps a domain failure as a
`ServiceValidationError` — RED on current code, GREEN after
- [ ] (optional) toxiproxy e2e: trigger with the writer cut → HTTP 500
generic body, no DB host in the response

## Summary
Under high request load the webapp spends most of its CPU inside
react-router's `matchRoutes`, not in application code.
`@remix-run/router@1.23.2` (the React Router v6 / Remix 2 core)
re-flattens, re-ranks, and recompiles the entire route table on every
request, and with the webapp's ~436 routes that cost dominates once
request rates climb. There is no `NODE_ENV` gate, so production pays it
too.
This adds a pnpm patch that memoizes the parts that depend only on the
static route manifest: it caches the flattened/ranked branches per route
tree, hoists the loop-invariant `decodePath` out of the match loop, and
caches compiled path regexes.
## Benchmark
CPU profile over the same load (100 concurrent tag feeds, ~425 req/s),
`NODE_ENV=production`, before vs after the patch:
| Metric | Before | After |
| --- | --- | --- |
| Active CPU (self-time over the window) | 28.3s | 18.5s (-34%) |
| Route-matching self-time | 19.2s | 7.5s (-61%) |
| Event-loop lag p99 | 322ms | 113ms (-65%) |
| Idle headroom | 26% | 52% |
Application/realtime code was ~0% of CPU in both profiles; the
bottleneck was entirely generic per-request route matching.
## Why a patch instead of an upgrade
The inefficiency is acknowledged upstream
([remix-run/react-router#8653](https://github.com/remix-run/react-router/issues/8653)).
A contributor PR doing exactly this
([remix-run/react-router#14866](https://github.com/remix-run/react-router/pull/14866))
was closed in favor of a narrower fix
([remix-run/react-router#14967](https://github.com/remix-run/react-router/pull/14967),
branch caching only, shipped in React Router v7), with the maintainer
suggesting patch-package as the interim until the Remix 3 route-pattern
rewrite (see
[remix-run/remix#4786](https://github.com/remix-run/remix/discussions/4786)).
We are on the v6-era core and cannot pick up even the partial fix
without a framework migration, so this patch is the sanctioned stopgap,
and it also includes the compiled-regex cache the merged PR left out.
[`patches/README.md`](https://github.com/triggerdotdev/trigger.dev/blob/perf/react-router-route-matching/patches/README.md)
documents the full rationale, the safety argument (deterministic,
internal-only, bounded caches), and when to remove the patch.
## Summary
A new guide for connecting a database to your tasks: where to create the
client, how to size the connection pool against your provider's limit,
when to reach for a pooler, and how to release connections at waits so
you don't hit "too many connections" or crash on resume.
It covers node-postgres, Prisma, Drizzle, and MongoDB, with researched
direct and pooled connection limits for the common Postgres providers
(Supabase, Neon, RDS, PlanetScale) and MongoDB Atlas. The page lives
under Documentation, Troubleshooting, and is linked from the chat agent
docs (overview, lifecycle hooks, chat.local, and the database
persistence pattern).
## Summary
On every `main` build, once the webapp image is pushed to the registry,
the publish workflow emits a cross-repo `repository_dispatch` event
(`main-image-published`) carrying a digest-pinned image ref. Other
repositories in the org can subscribe to that event and build or deploy
from the exact artifact, instead of chasing the moving `main` tag.
## Design
`publish-webapp.yml` now exposes the pushed multi-arch index digest as a
workflow output. `publish.yml` adds a `dispatch-main-image` job (after
`publish-webapp`) that builds `<image_repo>@<digest>` and sends the
dispatch via the same pinned `peter-evans/repository-dispatch` action
already used elsewhere in this repo, authed with `CROSS_REPO_PAT`.
It fires only when the published tag is `main`, so semver releases and
other tag builds are excluded, and only from the canonical repo so forks
never dispatch. The payload is JSON-escaped with `jq`.
## Problem
Two backward-pagination bugs in `ClickHouseRunsRepository.listRunIds`,
both pre-existing (they predate the composite-cursor work in #3852 and
were spotted during/after it):
**1. Wrong slice (straddled pages).** `listRunRows` fetches `page.size +
1` rows to detect `hasMore`. That extra row is the one *farthest from
the cursor* in both directions (forward orders DESC; backward orders
ASC), so it's always the *trailing* element. Forward correctly used
`rows.slice(0, size)`, but backward+`hasMore` used `rows.slice(1, size +
1)` — dropping the row *closest* to the cursor and keeping the has-more
sentinel. The page straddled two logical pages (one run from the correct
previous page + one from the page before it), so paging "newer" across a
boundary **repeated and skipped** runs.
**2. Stranded forward cursor on a partial backward page.** In the
backward `!hasMore` branch, `nextCursor` was `reversedRows.at(page.size
- 1)`. On a partial page (fewer than `page.size` rows — reachable via
`runs.list` by passing a forward page's cursor as `page[before]`), that
index overshoots → `undefined` → `nextCursor` becomes `null`, leaving no
way to page forward again.
## Fix
- **Slice:** both directions now slice `rows.slice(0, size)` (the
sentinel is the trailing element either way).
- **Partial-page cursor:** the backward `!hasMore` branch takes the
oldest row on the page, `rows.at(0)`, for `nextCursor` — equivalent to
the old expression for full pages, correct for partial ones.
Forward pagination, the cursor *values* for full pages, and the `hasMore
=== true` paths were already correct and are unchanged.
## Tests
`runsRepositoryCursor.test.ts` gains two cases (both fail on `main`,
pass here):
- **multi-page backward walk:** forward across all pages, then backward
from the last page — each backward page must *exactly* reproduce the
corresponding forward page (no straddling: `main` returns `{b,c}`
instead of `{c,d}`), and the full traversal covers every run once.
- **partial backward page:** backward onto a partial first page must
still expose a working forward cursor (and paging forward from it
reaches the rest) — `main` returns a `null` nextCursor.
The three existing cursor tests (forward completeness, backward
round-trip, legacy cursor) still pass.

## What
`dev` and `deploy` now fail with a clear error when two tasks are
defined with the same id — including across task types (e.g. a scheduled
task and a regular task sharing an id).
## Why
Tasks are registered into the resource catalog keyed by id, so a second
definition with the same id silently overwrote the first. One of the
tasks would just vanish from the worker with no warning — easy to miss,
hard to debug. (Any earlier duplicate-id check ran against the
post-registration task list, which is already de-duplicated, so it never
actually fired.)
## How
- **Detect at registration** (`@trigger.dev/core`):
`StandardResourceCatalog` records a collision when a task id is
registered more than once, capturing the files involved — the only point
where both definitions are visible before the id-keyed map collapses
them. Exposed via `listTaskIdCollisions()`.
- **Fail indexing** (`trigger.dev` CLI): both index workers report
collisions via a new `TASKS_FAILED_TO_INDEX` message;
`indexWorkerManifest` rejects with a new `DuplicateTaskIdsError`. `dev`
renders a dedicated error (offending ids + files + docs link); `deploy`
fails with the same message. Runtime worker boot is unaffected — it
never reads the collisions.
- **Server-side backstop** (webapp): background-worker registration also
rejects duplicate ids with a clear `ServiceValidationError`, so
duplicates are caught even from an older CLI.
## Testing
- Unit tests for collision collection in the catalog and for the
error-message formatting (standard, same-file, and 3+-definition cases).
- Verified end to end against a local webapp: a project with a regular
task and a scheduled task sharing an id now fails `dev` with the
dedicated error; a project with distinct ids still starts normally.
## Changeset
Patch for `@trigger.dev/core` and `trigger.dev`.

## Summary
- `internal-packages/rbac/src/index.ts` — in `LazyController.load()`'s
catch block, throw an Error when `process.env.REQUIRE_PLUGINS === "1"`
instead of silently falling back. The throw is captured into the lazy
controller's init promise, so it surfaces on the first method call.
- `apps/webapp/app/routes/healthcheck.tsx` — `await
rbac.isUsingPlugin()` after the DB ping. With `REQUIRE_PLUGINS=1` and a
failed plugin load, the throw surfaces here and the healthcheck returns
500 → readiness probe fails → rollout is rolled back. Noop for
self-hosters.
- `.server-changes/require-plugins-fail-fast.md` — server-changes entry.
- `internal-packages/rbac/src/require-plugins.test.ts` — 4 unit tests
covering loader branching: unset → fallback, `=1` → throw,
`forceFallback: true` wins, only exactly `"1"` enforces.
- `internal-packages/testcontainers/src/webapp.ts` — adds
`requirePlugins?: boolean` to `StartWebappOptions`. Implies
`forceRbacFallback: false`.
- `apps/webapp/test/healthcheck-require-plugins.e2e.test.ts` — e2e
closes the loop: spawns a real webapp, hits `/healthcheck` via HTTP,
asserts 500 with `REQUIRE_PLUGINS=1` and 200 without.
## Motivation
Today the RBAC plugin loader catches any plugin-load failure (missing
module, broken transitive dep, init throw) and silently returns the
default fallback implementation. This is the correct behaviour for
self-hosters who don't ship the plugin — but it's dangerous in
deployments where the plugin is expected to load: an
accidentally-missing or broken plugin would silently disable
enforcement.
`REQUIRE_PLUGINS=1` makes the loader fail loudly in those deployments.
The variable name is intentionally plural and generic — future plugin
contracts (audit logs, SSO) can read the same flag without renaming.

## Summary
Runs routed onto a dedicated scheduled worker queue were showing under a
phantom region in the dashboard, run details, and the API, and slipped
through region filters. They now resolve to their real region
everywhere.
## Fix
A worker queue can carry a `:scheduled` suffix that routes
scheduled-lineage runs onto their own list. That suffix is an internal
routing detail, but it was leaking anywhere the worker queue is read as
a region. A `baseWorkerQueue` helper strips any `:<class>` suffix back
to the base region (region names never contain a colon, so it's
everything before the first colon) and is applied at every region read
site: the runs list, run detail, the public API, and replay's region
override. The runs-replication writer also stores the base region in
ClickHouse so the region filter matches.
## Summary
`trigger init` now sets up your AI coding assistant as part of project
setup. Instead of the old either/or "MCP or CLI" prompt, it offers the
MCP server and agent skills together, then asks whether to scaffold with
the CLI or let your assistant do it.
A new `getting-started` agent skill backs that hand-off: it teaches the
assistant the bootstrap recipe (install the SDK, write
`trigger.config.ts`, scaffold a first task, wire tsconfig/gitignore, run
`trigger dev`) and is explicit about the two steps that genuinely need a
human (`trigger login` and copying the DEV secret key from the
dashboard). It ships in the CLI alongside the existing skills,
version-matched to your SDK.
Prompt-once gating is shared, so opting in or out during `init` means
`trigger dev` won't ask about skills again.
## Summary
The container publish workflows hardcoded `ghcr.io/triggerdotdev/...` as
the image destination. As a result, a fork that builds on push-to-`main`
(or on the worker publish tags) would attempt to push to — and attest —
the upstream packages rather than its own, which fails on permissions
and is surprising besides.
This makes the image destination configurable via a single
`IMAGE_REGISTRY` repository variable, while leaving the upstream
defaults byte-identical:
- **Single source of truth** (`publish.yml`): a `resolve-registry` job
resolves the target registry namespace once — `IMAGE_REGISTRY`
repository variable, defaulting to `ghcr.io/${{ github.repository_owner
}}` — and passes it down to every publish job as an `image_registry`
input. So a fork publishes to its own namespace automatically with no
configuration.
- **Webapp** (`publish-webapp.yml`): the image now lives at
`<registry>/<repo-name>` (e.g. `ghcr.io/<owner>/trigger.dev`). The
provenance attestation and the downstream Trivy scan follow the same
computed repo via the `image_repo` workflow output.
- **Workers** (`publish-worker.yml`, `publish-worker-v4.yml`): build
under `<registry>/<worker-name>`. They keep a `vars.IMAGE_REGISTRY ||
ghcr.io/<owner>` fallback so they still resolve correctly on their
direct `infra-*` / `re2-*` push triggers (which bypass the parent
workflow).
A single `IMAGE_REGISTRY` namespace variable now governs both webapp and
workers (the earlier `WEBAPP_IMAGE_REPO` full-path override is dropped,
removing the full-path/namespace asymmetry). When `IMAGE_REGISTRY` is
unset, every resolved image name is exactly what it is today, so there
is no change for this repo.
## Test plan
- [x] `actionlint` passes on all four workflows
- [ ] On merge, confirm the webapp publish still pushes
`ghcr.io/triggerdotdev/trigger.dev:main` + the commit-SHA tag (defaults
unchanged)

## Summary
The `mollifier.decisions` metric only carried an `outcome` label, so for
an org that has the mollifier enabled there was no way to see how often
its triggers pass through the gate instead of being diverted — making it
hard to tell why the trip isn't firing for an opted-in org.
This adds two bounded labels: `enrolled` (`"true"`/`"false"`, the
per-org flag) and `org` (the org id, attached **only** when `enrolled`
is true). For an enrolled org you can now compare directly:
`mollifier.decisions{outcome="pass_through", enrolled="true",
org="<id>"}` vs `{outcome="mollify", ...}`.
## Design
`recordDecision` now takes an options object (`{ reason?, enrolled,
orgId? }`). The `org` label is restricted to the enrolled cohort to keep
cardinality bounded — the guard lives in a pure `decisionLabels` helper,
so a non-enrolled org id can never be attached even if one is passed.
The enrolled set is small and capped operationally.
The per-org flag is resolved once at the top of `evaluateGate`
(in-memory, no DB round-trip on the trigger hot path) so every decision
— including the debounce / one-time-use-token / triggerAndWait bypasses
— is labelled consistently.
## Test plan
- [x] `mollifierGate.test.ts` cascade asserts `enrolled`/`org` on every
gate branch
- [x] `mollifierDecisionLabels.test.ts` (new) proves `org` is dropped
for non-enrolled even when an id is passed (cardinality guard)
- [x] `vitest run mollifierGate mollifierDecisionLabels` — 34/34 pass
- [x] `pnpm run typecheck --filter webapp` clean

Add an optional network_labels field to the internal compute client's
create and restore request schemas and forward per-VM endpoint labels on
both paths, so a restored VM keeps the same labels as a freshly-booted
one. Mirrors the label the Kubernetes workload manager already sets on
the run pod.

## Summary
`trigger skills` installs Trigger.dev agent skills into your coding
agent so it knows how to write Trigger.dev code: tasks, schedules,
realtime, and `chat.agent` AI agents. The skills are `SKILL.md` files
(the open Agent Skills format) bundled with the CLI and copied into each
tool's native skills directory (Claude Code, Cursor, GitHub Copilot, and
Codex / `AGENTS.md`), version-matched to the CLI you run. `trigger dev`
offers to install them on first run, and a one-line always-on pointer is
written into your `CLAUDE.md` / Cursor rules / etc. so the agent always
knows which skills are available and loads the right one on demand.
This replaces the old `install-rules` command, which stays as an alias.
Four skills ship to start: `authoring-tasks`, `realtime-and-frontend`,
`authoring-chat-agent`, and `chat-agent-advanced`.
## Problem
`ClickHouseRunsRepository.listRunIds` / `listRuns` order results by the
composite key `(created_at, run_id)`, but the cursor predicate cut on
`run_id` **alone**:
```ts
.where("run_id < {runId: String}", { runId: cursor })
.orderBy("created_at DESC, run_id DESC")
```
This is only sound when `run_id` lexicographic order matches
`created_at` order. `run_id`s are cuids — only coarsely time-sortable —
so when a burst of runs is created within a sub-second window, the two
orders can diverge. When they do, the next-page predicate (`run_id <
cursor`, where `cursor` is the *last* page element = the smallest
`created_at`, not necessarily the smallest `run_id`):
- **re-includes** rows already returned on a previous page (duplicates),
and
- **skips** rows it should have returned (silent data loss).
For bulk **replay** this caused runs to be replayed more than once
(replay has no idempotency guard). For the dashboard and the `runs.list`
API it could silently repeat or skip runs at page boundaries.
## Fix
Make the cursor predicate match the composite ordering:
- Cursors now encode the full `(created_at, run_id)` key as an **opaque
URL-safe base64 token**
(`base64url({"c":<createdAtMs>,"r":"<runId>"})`), and the query cuts on
the matching tuple — `(created_at, run_id) < (…)` forward / `> (…)`
backward.
- The `ORDER BY` is unchanged, so the query stays aligned with the
table's primary key — no performance regression (the tuple range
predicate is actually more index-friendly than `run_id <` alone).
- Cursors are **server-issued opaque tokens** (the SDK only echoes
`pagination.next` / `pagination.previous` back), so this needs **no
client/SDK update**. Legacy cursors were the bare internal `run_id`;
they're detected by decode failure (a cuid isn't a valid base64-wrapped
JSON payload) and fall back to the old `run_id`-only predicate, so
in-flight cursors keep working and drain naturally. New cursors also no
longer expose a bare internal run id.
- `listRunIds` is now the single cursor-aware list primitive: it returns
`{ runIds, pagination: { nextCursor, previousCursor } }`, and `listRuns`
builds on it (one place constructs cursors). Bulk actions consume the
same method and advance by `pagination.nextCursor`, finishing when it's
`null`.
- `getTaskRunsQueryBuilder` now also selects
`toUnixTimestamp64Milli(created_at) AS created_at_ms`, using a dedicated
`TaskRunListQueryResult` schema. The shared `TaskRunV2QueryResult` stays
`run_id`-only so the run-engine pending-version lookup
(`getPendingVersionIdsQueryBuilder`, which selects only `run_id`)
doesn't fail validation on a column it doesn't query.
## Tests
New `runsRepositoryCursor.test.ts` (testcontainer-backed, real
Postgres→ClickHouse replication):
- **forward** pagination returns every run exactly once when `run_id`
order is the reverse of `created_at` order (reproduces the
duplicate/skip bug — fails on `main`; this
walk-until-`nextCursor`-null-and-assert-complete is exactly the bulk
action's iteration),
- **backward** pagination round-trips to the previous page across a
boundary,
- **legacy** bare-`run_id` cursor still uses the old predicate
(backwards compatibility).
The existing `runsRepository` suites (part1–4) still pass; `part4`'s
`count new runs with listRunIds` test was updated for the new `{ runIds,
pagination }` return shape, and the `clickhouse` `taskRuns`
query-builder snapshots were regenerated for the added `created_at_ms`
column.
## Notes
- Separate, pre-existing issue (out of scope, not introduced here):
`listRuns`' backward display-slicing (`rows.slice(1, size+1)` when
`hasMore`) has an off-by-one that can return a straddled page. Tracked
separately.

Two small hygiene tweaks to **dev-only** images:
- `docker/Dockerfile.postgres`: add `--no-install-recommends` to the
partman install (leaner image, skips unneeded recommended packages).
- `internal-packages/clickhouse/Dockerfile`: run the migration helper as
a non-root user.
Both are local-dev images (the `pnpm run docker` stack) - no impact on
the published webapp image, prod, or self-hosting.
Speeds up and de-flakes the unit-test suite: testcontainers booted once
per vitest worker (per-test isolation kept only where a test runs
background redis work that outlives it), a duration-weighted shard
sequencer so each shard does roughly equal work, the slowest suites
split, two genuine flakes fixed (`streamBatchItems` shared-redis leak;
run-engine waits that relied on fixed sleeps), and transient DockerHub
pulls retried.
**Timings (CI, per-shard wall):** worst unit-test shard ~771s → ~294s;
packages/webapp shards ~250-270s, most internal ~190-240s. All 25 shards
green.
A shard breaks down as ~70s fixed setup (install / image-pull /
generate) + ~70s cold `^build` + the actual container tests. So the
remaining cost is mostly the tests themselves plus that fixed setup.
**Next (separate, timings):**
- **typecheck (~6m24s)** — the slowest check overall; bound by
full-graph `tsc`, not the TS version (a TS6 branch is still ~6m17s). The
real lever is **tsgo** (the Go compiler).
- Possible later: turbo CI caching could trim the ~70s cold build on
*warm* runs, but it's conditional (cold runs rebuild anyway) and doesn't
touch setup or test time — secondary.
`cli-v3` e2e and `sdk-compat` are path-gated (don't run on test-infra
changes) and already comfortably fast.
## Summary
Adds a trace export to the run page. From the new **Export trace** menu
you can
copy a run's full trace to the clipboard as Markdown (for pasting into
an AI
assistant) or download it as a flat Log, a Markdown table, or JSON
Lines.
Internal engine-debug events are filtered out by default, and errors are
surfaced inline with their message.
## Design
The export streams events from the store to the gzipped response one at
a time
and never materialises the span tree, so a trace of any size exports
with
bounded memory and without stalling the server. Output is flat and
chronological: each line carries its own `spanId ← parentSpanId`, so the
hierarchy is reconstructable without nesting. Formats share a single
streaming
pipeline and are pluggable via `?format=log|jsonl|markdown`, so adding a
format
is an isolated change.

A unit-test shard recently failed on a timing race rather than a real
regression - a run-engine waitpoint test sleeps 1250ms waiting on a
1000ms timeout that's processed by a ~1000ms worker poll, so on a
CPU-starved shard the margin evaporates and the whole matrix goes red.
Because `fail-fast` defaults on, that one flake cancels the sibling
shards, and the only recovery is re-running the entire matrix "just to
be sure" - which is itself slow.
This is the low-risk first pass at that pain:
- `fail-fast: false` on the webapp and internal shard matrices, so one
flaky shard no longer cancels its siblings. "Re-run failed jobs" now
re-runs just the failed shard instead of the whole matrix.
- CI-scoped `retry: process.env.CI ? 2 : 0` on the timing-sensitive
packages (`run-engine`, `redis-worker`, `schedule-engine`). Flakes
self-heal in CI; local runs stay at `retry: 0` so they still surface in
dev. A stopgap until the timing tests are made deterministic.
- `fetch-depth: 1` on the unit-test checkouts - they don't use git
history, so the full clone was wasted setup time across ~20 jobs.
- Reconcile the pre-pull image tags with what testcontainers actually
pulls (`redis:7-alpine` -> `redis:7.2`, `ryuk:0.11.0` -> `ryuk:0.14.0`)
and add `minio/minio:latest` to the webapp pre-pull. Otherwise those
images pull unauthenticated at test time and risk Docker Hub rate-limit
flakes (worst on fork PRs, where the authenticated pre-pull is skipped
entirely).
Deeper follow-ups - bigger runners, turbo remote cache, runtime-weighted
sharding, and the real root-cause fix (container reuse / template-DB
isolation + deterministic timing tests) - are tracked under TRI-10484.
Hardens the webapp Docker image and adds a CVE scan of each published
image.
- Base image `bullseye-slim` → `bookworm-slim` (Debian 12), pinned by
digest. Adds `apt-get upgrade` + `--no-install-recommends` + apt-cache
cleanup across the build stages so OS packages are patched at build
time.
- Moves the `react-email` CLI to `devDependencies` in
`internal-packages/emails` — only the `email dev` preview script uses
it; the runtime render path is `@react-email/render` +
`@react-email/components`. This also drops the bundled `esbuild` binary
from the production image.
- Bumps `goose` v3.26.0 → v3.27.1 and its Go builder image 1.23 → 1.26.
- Adds a reusable Trivy image-scan workflow wired into `publish.yml`, so
every published image (main builds and releases) is scanned for
OS-package CVEs right after it's pushed to GHCR. Report-only (writes to
the run summary), runs alongside the worker publishes so it never blocks
a deploy.
Verified locally: the image builds clean on the new base, and
`@react-email/render` carries no `esbuild` dependency so email rendering
is unaffected.
## Summary
The SDK and core packages run a second, forward-compat typecheck pass
(`tsc --noEmit -p tsconfig.ai-v7.json`) that remaps the `"ai"` import to
the ESM-only AI SDK 7 canary, so we catch source that only compiles
against one major. That pass inherited `composite: true` from the base
tsconfig, which makes `tsc` write a `.tsbuildinfo` even under
`--noEmit`.
Incremental buildinfo caches each file's resolved module format (CJS vs
ESM) and module resolution. When that state goes stale or is replayed,
the v7 pass can report spurious `TS1479` ("CommonJS module ... cannot
`require` an ECMAScript module") errors on the `"ai"` import even though
the source is fine in a clean checkout. Because this pass shares the
typecheck job that gates the Docker image publish, a spurious failure
there blocks publishing.
## Fix
Set `composite: false` and `incremental: false` on both
`tsconfig.ai-v7.json` files. The pass is `--noEmit` only, so it never
needed incremental state. Now each run is a clean, full check that
writes no buildinfo and can't replay stale resolution.
Verified: both `@trigger.dev/sdk` and `@trigger.dev/core` typecheck
green, and neither writes an ai-v7 `.tsbuildinfo` anymore.
## Summary
Opening or closing the Bulk action inspector should not affect the Runs
list, but it was still triggering refresh-related UI behavior. This PR
fixes that and smooths out a few related inspector interactions.
## Changelog
Stop reloading the runs list (and flashing its loading state) when
opening or closing the
Bulk action inspector. Filtering, pagination, and explicit refresh are
unaffected.
## Summary
Documents AI SDK 7 support in the AI Chat docs. Pairs with the SDK
change in #3833.
- The reference compatibility matrix now lists the v7 peer range and
adds an `@ai-sdk/otel` row.
- A new "AI SDK 7 telemetry" section covers the `@ai-sdk/otel` install,
the automatic registration, and the `TRIGGER_AI_SDK_OTEL_AUTOREGISTER`
opt-out.
- The quick start surfaces the supported `ai` versions (v5/v6/v7) up
front, near where you install.
## Summary
1 new feature, 8 improvements, 1 bug fix.
## Highlights
- Add optional `shouldPauseScaling` to the supervisor consumer pool
scaling options to freeze scale-up while it returns true (scale-down
stays allowed).
([#3836](https://github.com/triggerdotdev/trigger.dev/pull/3836))
## Improvements
- The MCP server no longer tells the AI agent to wait for a run to
complete after every `trigger_task` call. Waiting is now opt-in: the
agent only waits when you ask it to (for example "trigger and then wait
for it to finish"). This avoids burning tokens polling runs you didn't
need to block on and keeps responses clearer.
([#3838](https://github.com/triggerdotdev/trigger.dev/pull/3838))
- Update the bundled OpenTelemetry packages to their latest releases
(`@opentelemetry/sdk-node` 0.218.0, `@opentelemetry/core` 2.7.1,
`@opentelemetry/host-metrics` 0.38.3).
([#3810](https://github.com/triggerdotdev/trigger.dev/pull/3810))
- `envvars.upload` now accepts an optional `isSecret` flag, letting you
create the imported variables as secret (redacted) environment
variables. When omitted, variables default to non-secret.
([#3809](https://github.com/triggerdotdev/trigger.dev/pull/3809))
- Offload large trigger payloads to object storage before sending the
trigger API request. The SDK uploads packets at or above the existing
128KB limit and sends an `application/store` pointer instead of
embedding large JSON in the request body. `TriggerTaskRequestBody` now
validates that `application/store` payloads are non-empty storage paths.
([#3785](https://github.com/triggerdotdev/trigger.dev/pull/3785))
- Make mollifier buffer and drainer internals configurable.
`MollifierBuffer` now accepts `ackGraceTtlSeconds`,
`maxRetriesPerRequest`, `reconnectStepMs`, and `reconnectMaxMs` options,
and `MollifierDrainer` accepts `maxBackoffMs` and `backoffFloorMs`. All
default to their previous hardcoded values, so existing behaviour is
unchanged.
([#3822](https://github.com/triggerdotdev/trigger.dev/pull/3822))
- `MollifierDrainer` accepts a `drainBatchSize` option (default 1) that
controls how many entries are popped per env per tick — in-flight
handlers remain capped by the global `concurrency`. `MollifierBuffer`
also gains `getDrainingCount()` / `listStaleDraining()`, backed by a new
`mollifier:draining` ZSET maintained atomically with
pop/ack/fail/requeue (observability-only).
([#3797](https://github.com/triggerdotdev/trigger.dev/pull/3797))
- Adds AI SDK 7 support. The `ai` peer range now includes v7, and the
`chat.agent` / chat surfaces work against v7's ESM-only build. On v7,
install `@ai-sdk/otel` alongside `ai` and the SDK registers it for you
so `experimental_telemetry` spans keep flowing into your run traces (v7
stopped emitting them from `ai` core). v5 and v6 keep working unchanged.
([#3833](https://github.com/triggerdotdev/trigger.dev/pull/3833))
- `useTriggerChatTransport` now recovers when restored session state
points at a session that no longer exists in the current environment
([#3816](https://github.com/triggerdotdev/trigger.dev/pull/3816))
## Bug fixes
- Fix `@trigger.dev/core` build: cast the underlying log record exporter
when calling `forceFlush` so it typechecks against the updated
OpenTelemetry `LogRecordExporter` type (which no longer declares
`forceFlush`).
([#3829](https://github.com/triggerdotdev/trigger.dev/pull/3829))

([#3785](https://github.com/triggerdotdev/trigger.dev/pull/3785))
Payload uploads use the same resolved `ApiClient` as the trigger call
(including `requestOptions.clientConfig`), not only the global
`apiClientManager.client` — so custom `baseURL`, access token, and
preview branch apply to both presign and trigger.

validates that `application/store` payloads are non-empty storage paths.
([#3785](https://github.com/triggerdotdev/trigger.dev/pull/3785))
Payload uploads use the same resolved `ApiClient` as the trigger call
(including `requestOptions.clientConfig`), not only the global
`apiClientManager.client` — so custom `baseURL`, access token, and
preview branch apply to both presign and trigger.

## Summary
The Prisma CLI was missing from production builds of the webapp image,
so anything that shells out to `prisma` at startup failed. The container
entrypoint and the standalone migration step both run `prisma migrate
deploy` / `prisma migrate status`, and those broke with `Command
"prisma" not found`.
## Fix
`prisma` was a `devDependency` of `@trigger.dev/database`. It had only
been landing in the pruned `--prod` install as a side effect of pnpm
auto-installing it as a peer of `@prisma/client`. A recent dependency
change shifted peer resolution so prisma stopped being materialized into
the production tree, and the CLI disappeared from the image.
Moving `prisma` into `dependencies` of `@trigger.dev/database` makes the
CLI an explicit part of production installs. It lands in the webapp
image only: the separately deployed supervisor, coordinator, and
provider images don't reach the database package in their production
trees (`core` only `devDepends` on it, so it isn't transitive), so
they're unaffected.
Verified against a locally built production image: `pnpm --filter
@trigger.dev/database exec prisma --version` now resolves the CLI and
the schema engine instead of failing.
The supervisor can now pause dequeuing - and freeze consumer-pool
scale-up - when a backpressure signal says the cluster can't place more
work, then ramp dequeuing back up gradually once it clears. The signal
is a verdict published to a Redis key by a cluster-side component; the
supervisor reads it on a short refresh and gates `preDequeue` on it.
Off by default (`TRIGGER_DEQUEUE_BACKPRESSURE_ENABLED`). Everything
fails open: a missing, stale, or unreadable verdict never pins the
brake, and the hot-path read is a synchronous cached lookup with no I/O.
The scale-up freeze leaves scale-down untouched, and on release the
resume is ramped so a deep queue isn't hammered all at once.
Dry-run is on by default (`TRIGGER_DEQUEUE_BACKPRESSURE_DRY_RUN`): even
once enabled it only logs what it would have done, and surfaces the
computed state through metrics, until explicitly set to act. Prometheus:
`supervisor_backpressure_engaged`, `_dry_run`,
`_skipped_dequeues_total`.

## Summary
Scheduled runs and their descendants can now be routed to a dedicated
per-region worker queue, processed by a separate worker fleet, so a
burst of scheduled crons no longer competes with standard and agent runs
for the same queue and inflates their startup latency. It is off by
default and enabled per organization via a feature flag (with a global
default), so nothing changes until it is turned on.
## Design
At trigger time, any run whose lineage originates from a schedule
(`rootTriggerSource === "schedule"`, which already propagates from a
scheduled run down to all of its children) gets its worker queue
suffixed with `:scheduled`. The worker queue name is an opaque string
persisted on the run and used verbatim by enqueue and dequeue, so this
needs no Lua, message-envelope, or concurrency changes. Concurrency
stays keyed by environment and queue, not by worker queue.
On the consumer side, the dequeue endpoint gains an optional
`queueClass` selector. A supervisor sends `queueClass: "scheduled"` and
the server derives the actual queue from the worker's own group, so a
token can only ever reach its own region's queues. A fleet picks its
class with the `TRIGGER_WORKER_QUEUE_CLASS` env var (`default` or
`scheduled`), so a dedicated scheduled fleet can run alongside the
standard one.
Verified end to end against a local managed-worker setup: scheduled runs
route to the dedicated queue, are drained only by the scheduled fleet,
and standard runs are left untouched.
## Summary
The Trigger.dev MCP server told the AI agent to wait for the run to
complete after every `trigger_task` call. The agent followed that
instruction even when the user only wanted to fire-and-forget, which
burned tokens polling runs nobody needed to block on and made responses
less clear.
Waiting is now opt-in. After triggering, the response tells the agent
the run is executing in the background and to only wait if the user
asked it to (for example "trigger and then wait for it to finish"). The
`trigger_task` tool description is updated to match. The
`wait_for_run_to_complete` tool itself is unchanged, so explicit waits
still work.
## Summary
This PR adds packet path validation before key construction and
presigning. Invalid paths are rejected before reaching either
object-store client implementation, ensuring consistent behavior
regardless of the underlying storage configuration.
## Summary
Adds support for Vercel AI SDK 7. The `ai` peer range now includes v7,
and the `chat.agent` / chat surfaces work against v7's ESM-only build.
v5 and v6 keep working unchanged, so this is additive.
## Telemetry on v7
On v7, model-call spans moved out of `ai` core into the separate
`@ai-sdk/otel` adapter, so `experimental_telemetry` alone produces
nothing until an integration is registered. Install `@ai-sdk/otel`
alongside `ai@7` and the SDK registers it once per worker at chat agent
boot, so spans keep flowing into run traces with no extra setup.
If you (or a library you import) already register `@ai-sdk/otel`, the
SDK detects the existing integration and skips its own registration, so
you won't get duplicate spans. Set `TRIGGER_AI_SDK_OTEL_AUTOREGISTER=0`
to disable auto-registration entirely.
## Notes
`ai@7` is ESM-only, which tripped TS1479 in the SDK's CommonJS build.
Runtime value imports from `ai` are isolated behind a paired ESM/CJS
shim so both module formats resolve the right form; type-only imports
stay as direct `import type` at their use sites.
## Summary
Three fixes to the AI agent surface in the dashboard, all surfaced while
verifying AI SDK 7 support (the SDK side is #3833):
- **AI SDK 7 telemetry rendering.** The generation-span inspector and
run metrics now read both the v6 (`ai.*`) and v7 (`gen_ai.*`) telemetry
attribute shapes. On v7 the Messages, Provider, and Tools views showed
empty/unknown before; now they render correctly.
- **HITL approvals in the conversation view.** The agent conversation
view renders human-in-the-loop tool approvals and denials (awaiting
approval, approved, denied with reason) instead of leaving the tool part
blank. This gap predated v7.
- **Chat snapshot store mismatch.** Chat session snapshots now resolve
through a single storage-key helper shared by the SDK write and the
dashboard read. Previously the write applied the default object-store
protocol to the key while the read fell back to a different store, so
the dashboard 404'd on the snapshot and showed only a partial
conversation.
## Summary
On a busy webapp the trace/log/metric ingestion path emits several
`info` logs per insert batch, which makes up the bulk of the service's
log output. This moves that per-batch chatter to `debug` and adds an
opt-in to drop successful HTTP access logs, cutting log volume with no
loss of error signal.
## Details
The per-batch ClickHouse insert logs, the flush scheduler's concurrency
adjustments, and the event-loop utilization sample (already exported as
a metric, so the log line was redundant) now log at `debug`. Error and
warning logs are untouched.
New `HTTP_ACCESS_LOG_DISABLED=1` env var: when set, the HTTP access
logger skips successful (2xx) requests while still logging non-2xx
responses. Defaults off, so existing deployments are unchanged.
## Summary
This PR improves performance across the Environment Variables page.
## Changes
### Targeted value loading
- load only the non-secret (environmentId, key) pairs required by the
page. Secret values continue to be redacted in the UI.
### SSR windowing + virtualization
- SSR-render only the first 50 rows
- hydrate those rows
- virtualize the remaining dataset client-side
- search is now URL-driven during SSR, ensuring deep links such as
`?search=DATABASE_URL`
### Lightweight 'Create' flow
- 'Create' page no longer loads the full Environment Variables dataset.
## Results
Large projects no longer render thousands of rows during SSR.
Example (~11k rendered rows):
Metric | Before | After
-- | -- | --
Document size | ~150 MB | ~5 MB
SSR rows | ~11k | 50
Browser DOM rows | Thousands | ~26–38
## Summary
The mollifier had ~21 behavioural constants baked in as hardcoded values
— the buffer's ack-grace TTL and Redis retry/reconnect tuning, the
drainer's poll interval and backoff envelope, the pre-gate idempotency
claim TTL/wait/poll, the buffered-run mutate-with-fallback wait loop,
the metadata CAS retry budget and backoff, the stale-sweep scan bounds,
and the draining-gauge interval. None could be adjusted without a code
change, which makes tuning the system under production load impossible.
This exposes all of them as `TRIGGER_MOLLIFIER_*` environment variables,
each defaulting to its previous hardcoded value. Behaviour is identical
unless an operator sets a var, so it's a safe no-op deploy.
## Design
The package-level classes (`MollifierBuffer`, `MollifierDrainer` in
`@trigger.dev/redis-worker`) gain optional constructor options
defaulting to the old constants — backward compatible, hence a patch
changeset. The webapp factories and worker bootstraps read the env and
pass them through. The route- and concern-level pure helpers
(mutate-with-fallback, metadata mutation, idempotency claim, stale-sweep
state) keep their existing `?? DEFAULT` option fallbacks and are fed env
values at their call sites, so they stay unit-testable without importing
`env.server`.
## Test plan
- [x] `@trigger.dev/redis-worker` builds
- [x] webapp typecheck passes
- [x] mollifier buffer + drainer testcontainer suites pass (modulo a
couple of pre-existing flaky timing tests)
- [x] Reviewer: confirm the `TRIGGER_MOLLIFIER_*` env var names match
ops conventions

Adds backward-compatible support for large trigger payloads by reusing
the existing object-storage packet flow.
Large payloads are uploaded to object storage before the trigger request
is sent. The trigger API receives a small application/store pointer
payload instead of embedding large JSON bodies in the request.
Small payload behavior is unchanged.
## Summary
Adds a nullable `pricing_unit` column to the LLM model registry's
`llm_models` table, recording how each model is billed ("tokens",
"characters", "images", "minutes", "requests", "free", "not_findable").
It lets pricing-coverage reporting exclude models that aren't priced
per-token (image/video/audio models currently drag the "% priced" number
down even though they can never carry a per-token price), and lays the
groundwork for non-token pricing.
The default model catalog is entirely per-token, so `seed` and
`syncLlmCatalog` set `pricing_unit="tokens"` on those rows. The admin
LLM model form (create + edit) and the admin API get a pricing-unit
selector so admin-curated models can set it; existing rows can stay
unset.
Auto-discovered models get their unit from the model-registry pipeline,
which lands separately.

## Summary
When a chat's restored session state points at a session that no longer
exists in the current environment — for example a `sessions` entry that
was persisted against a different trigger environment —
`useTriggerChatTransport` assumed the session was live and never created
a real one. The next message then failed with a 404 and the chat
couldn't send.
## Fix
`callWithAuthRetry` now treats a 404 from a session-PAT-authed call as
"this session doesn't exist here". After the existing 401/403 token
refresh, a 404 recreates the session via `startSession`, drops the stale
`lastEventId` resume cursor (it pointed at another environment's
stream), and retries the send once. When `startSession` isn't configured
the transport throws a clear message instead of a bare 404.
Routine maintenance pass on a few transitive `pnpm.overrides`.
- `fast-uri` / `fast-xml-builder`: add overrides pinning to current
releases (`3.1.2` / `1.1.7`).
- `protobufjs` / `qs`: bump existing override pins that had fallen a
patch behind (`7.5.6` / `6.15.2`).
Overrides-only - no first-party code changes; lockfile regenerated to
match. Verified the affected transitives resolve to the pinned releases
via `pnpm why -r`.

## Testing
Upgraded the email packages in `internal-packages/emails`:
| Package | Before | After |
| --- | --- | --- |
| `@react-email/components` | `0.0.16` | `1.0.12` |
| `@react-email/render` | `^0.0.12` | `^2.0.8` |
| `react-email` (CLI) | `^2.1.1` | `^6.5.0` |
| `react-dom` | _(missing)_ | `^18.2.0` (now a required peer of render)
|
**Breaking change handled:** `render()` is now async (`Promise<string>`)
in `@react-email/render` v1+. Added `await` in the `aws-ses`, `smtp` and
`null` transports. `EmailClient` and the webapp callers were already
async and needed no changes.
Verification:
- `pnpm run typecheck --filter emails` ✅
- `pnpm run typecheck --filter webapp` (consumer of the `emails`
package) ✅
- **Before/after render comparison**: rendered all 11 templates
(magic-link, invite, welcome, alert-attempt/run/error-group,
deployment-failure/success, mfa-enabled/disabled, bulk-action-complete)
to HTML with both the old and new packages and compared them visually +
via HTML diff. Output is visually identical. The only HTML changes come
from upstream improvements: `<Body>` now wraps content in a
`<table>`/`<td>` for better email-client compatibility, an
`x-apple-disable-message-reformatting` meta tag was added, and CSS
shorthand (e.g. `margin`) is now also emitted as longhand. No visual
regressions; the `CodeBlock`/dracula theme, buttons, and row/column
layouts all render correctly.
No changeset or `.server-changes/` entry is added: `emails` is a private
internal package (not under `packages/`), and there is no user-facing
behavior change.
---
## Changelog
Upgrade `react-email` and `@react-email/{components,render}` in
`internal-packages/emails` to their latest versions and adapt the mail
transports to the now-async `render()` API.
---
## Screenshots
Rendered email templates before vs after the upgrade (visually
identical):
**Before** (`@react-email/components@0.0.16`, `render@0.0.12`)
## Summary
A fresh clone running `trigger dev` against the local webapp shows the
run in the dashboard but an empty trace view.
`EVENT_REPOSITORY_DEFAULT_STORE` was unset in `.env.example`, so span
ingestion fell back to the `postgres` store while the rest of the local
stack (run replication, `CLICKHOUSE_URL`) is ClickHouse-backed.
Defaulting it to `clickhouse_v2` makes dev run traces show up out of the
box.
The reference/example projects (`references/`) now live in their own
repo, https://github.com/triggerdotdev/references, so their heavy,
frequently-changing dependencies are no longer part of this repo's
lockfile and tooling. This removes them here and repoints everything
that referenced them.
- Deletes `references/`; updates the pnpm workspace + lockfile.
- Clears the references-only CI rules and `.vscode` configs.
- Repoints the docs (contributor/agent + one public page) to the new
repo.
- `seed.mts` keeps the local-dev projects (hello-world, d3-chat,
realtime-streams).
Brings the OpenTelemetry packages up to the latest coherent release
across the webapp and the published packages (`@trigger.dev/core`, the
CLI, `@trigger.dev/sdk`) plus
`internal-packages/{tracing,testcontainers}`:
- `@opentelemetry/sdk-node` 0.218.0
- `@opentelemetry/core` 2.7.1
- `@opentelemetry/host-metrics` 0.38.3
We were already on the otel 2.x line, so this is a same-major minor move
- the versions are pinned to `@opentelemetry/sdk-node@0.218.0`'s own
declared dependency set so the experimental (0.2xx) and stable (2.x)
packages stay coherent (mixing them is the usual otel breakage).
**One code change:** otel 0.215 made `forceFlush()` a required method on
`LogRecordExporter`, so `ExternalLogRecordExporterWrapper` (core's
tracing SDK) gains a `forceFlush()` that delegates to the underlying
exporter.
**Notable upgrades along the way:** OTLP exporters can take a custom
HTTP agent (connection pooling/keepAlive on the export path), HTTP
request headers are captured at span creation, and core hot-path perf
improvements in 2.6.1/2.7. `host-metrics` 0.37→0.38 is a clean upgrade.
Patch changeset added for the three published packages. References
projects are intentionally untouched.
Verified: `@trigger.dev/core` / CLI / `@trigger.dev/sdk` build, webapp +
`@internal/tracing` typecheck - all green.
Adds wide-event observability for the supervisor: one flat-keyed JSON
line per dequeue iteration, workload-server route, and run socket
lifecycle event. Events carry `trace_id` sourced from the inbound W3C
traceparent plus `meta.run_id` and related identifiers, so they join
across services by run.
The outbound warm-start POST also forwards the inbound traceparent so
the upstream receiver continues the same trace instead of minting a new
one.
Off by default behind `TRIGGER_WIDE_EVENTS_ENABLED`. With the flag off,
no events are emitted, no ALS state is allocated, and the outbound
warm-start request is unchanged — every call site was audited to confirm
the off path is byte-identical to current behavior.
Dequeue-path phase timings recorded under `phase.<name>.duration_ms`:
`restore`, `warm_start`, `workload_create`. A `path_taken` extra
distinguishes `restore` / `warm_start` / `cold_create` /
`skipped_no_image`.
Refs TRI-9480.
## Summary
The Runs list now updates live without requiring a page refresh. Status
changes and other run fields are updated in place while runs are
executing.
When new runs matching the current filters are created, a "New runs
created" refresh button appears above the list.
Root runs now show a live child-run status breakdown directly in the
status tooltip.
### List live update
- Visible runs update in place while they are still running.
- A "New runs created" refresh button appears when new matching runs are
detected.
- Polling stops when all visible runs have finished and a refresh button
is already shown.
- Polling pauses when the browser tab is not visible.
- Runs list status updates and new-run detection share a single
runs/live polling path.
### Child-status tooltip
- Root run tooltips now display a breakdown of child run statuses.
- Child statuses are loaded when the tooltip opens (after a 400ms hover
delay).
- The tooltip stays up to date while child runs are still changing
state.
- Handles cases where child runs continue running after their parent run
has completed, or have not yet been created.
### Supporting changes
- Added hidden-tab awareness to polling.
- Added safeguards around polling inputs (`runIds` deduping and limits).
## Test plan
- [x] pnpm run typecheck --filter webapp passes
- [x] cd apps/webapp && pnpm run test
./test/presenters/mapRunToLiveFields.test.ts --run passes
- [x] cd apps/webapp && pnpm run test
./test/runsRepository.part2.test.ts --run -t "hasNewRuns" passes
### Manual smoke:
- [x] Active runs update without a page refresh.
- [x] A new matching run shows the refresh banner and the banner actions
work as expected.
- [x] Root run tooltips show live child-status updates and stop polling
once child runs settle.

## Problem
On environments where runs carry a Postgres-backed `taskEventStore`
value (`taskEvent` or `taskEventPartitioned`), OTLP ingest endpoints
(`POST /otel/v1/traces` and `/otel/v1/logs`) were returning HTTP 500.
**Root cause:** The org-scoped ClickHouse factory introduced in a recent
PR routes all OTLP spans through `getEventRepositoryForOrganizationSync`
→ `buildEventRepository`. That function only handles `"clickhouse"` and
`"clickhouse_v2"` store values and throws `Unknown ClickHouse event
repository store: <value>` for anything else. The throw occurred inside
the grouping loop of `#exportEvents`, unwinding the entire method and
returning 500 for the whole batch.
The OpenTelemetry collector's `otlphttp` exporter treats HTTP 500 as
non-retryable and drops the batch — causing real span loss.
**Fix:** Guard the `getEventRepositoryForOrganizationSync` call in
`#exportEvents` so it is only invoked for `clickhouse` / `clickhouse_v2`
store values. All other values are routed directly to the Postgres
`eventRepository`, matching the guard pattern already present in
`resolveEventRepositoryForStore` and `getEventRepositoryForStore` in
`eventRepository/index.server.ts`.
The ClickHouse factory call is also wrapped in a try/catch that falls
back to Postgres so any unexpected store value in a future OTLP batch
degrades gracefully instead of failing the whole request.
## Changes
- `apps/webapp/app/v3/otlpExporter.server.ts` — add Postgres routing
guard and try/catch fallback in `#exportEvents`
## Testing
The `eventRepository/index.server.ts` module already has the same guard
pattern thoroughly covered. The fix brings `#exportEvents` into
alignment with that existing, tested pattern. Manual verification:
confirm OTLP batches containing Postgres-store spans return 200 and
route to the correct repository.
## Summary
The environment variables import API now accepts an optional `isSecret`
flag, so imported variables can be created as secret (redacted)
environment variables instead of plaintext. When the flag is omitted,
variables default to non-secret, preserving existing behavior for CLI
deploys and dashboard imports.
This is useful for tools that push secrets into Trigger.dev (for
example, syncing from a secrets manager) and want them stored as secrets
rather than plain environment variables.
It's available through `envvars.import` in the SDK and the `POST
/api/v1/projects/{projectRef}/envvars/{slug}/import` endpoint, and is
honored for both regular and preview-branch environments.
```ts
await envvars.import("proj_1234", "prod", {
variables: { STRIPE_SECRET_KEY: "sk_live_..." },
isSecret: true,
});
```
## What
Adds [pkg.pr.new](https://pkg.pr.new) continuous preview releases. Every
push to a branch builds the public `@trigger.dev/*` packages and
publishes installable preview builds keyed by commit SHA — **without
touching the npm registry**. pkg.pr.new drops install instructions on
the associated PR:
```
npm i https://pkg.pr.new/@trigger.dev/sdk@<sha>
```
This lets reviewers and users try a branch (SDK, CLI, core, etc.) before
anything is released, separate from the changesets release, the manual
`--snapshot` prerelease, and the chat-prerelease flow.
## How
`.github/workflows/preview-packages.yml` (push trigger) → install →
generate Prisma → **stamp preview version** → build → `pkg-pr-new
publish`.
### The version stamp (the important part)
pkg.pr.new serves previews by SHA but does **not** rewrite the
package.json `version` field. If a preview shipped as `4.5.0-rc.4`, a
consumer who installed it would pin `4.5.0-rc.4` to the preview tarball
in their lockfile/cache — and a later `npm i
@trigger.dev/sdk@4.5.0-rc.4` from npm could resolve to the stale
preview. This is a known, by-design gap in the tool
(stackblitz-labs/pkg.pr.new#250, #390).
`scripts/stamp-preview-version.mjs` runs **before the build** and
rewrites every public package to a unique `0.0.0-preview-<sha>`. The
`0.0.0-` prefix can never satisfy a real semver range, so the collision
is structurally impossible (same convention React/Next canaries use).
Running before the build also means `scripts/updateVersion.ts` bakes the
preview version into the runtime `VERSION` constant, so previews are
self-identifying (`trigger --version`, the `x-trigger-cli-version`
header, the MCP server version) instead of all reporting the RC version.
Sibling `workspace:` specifiers are relaxed to `workspace:*` so `pnpm
pack` resolves them against the rewritten versions — `packages/python`
pins peerDependencies as `workspace:^4.5.0-rc.4`, which would otherwise
be unsatisfiable once the version changes. Non-public deps
(`@trigger.dev/database`, `@internal/*`) are left untouched. All
mutations happen on the ephemeral CI checkout; nothing is committed.
## GitHub App
The pkg.pr.new GitHub App is **already installed** on
`triggerdotdev/trigger.dev` (has been for a while), so no setup is
needed. Confirmed live — this branch's pushes published all 10 public
packages, e.g.
```
pnpm add https://pkg.pr.new/@trigger.dev/sdk@e4dfc59
```
## Fork limitation
pkg.pr.new authenticates with a GitHub Actions OIDC token, which GitHub
does not issue to `pull_request` workflows from forks. The `push`
trigger therefore covers branches pushed to this repo (core team), not
external fork PRs. Fork coverage would need a `workflow_run` two-stage
setup; left out for now.
## Notes
- Pinned `pkg-pr-new@0.0.75` (no Node engine constraint; Node 20 CI is
fine).
- pkg.pr.new
[#525](https://github.com/stackblitz-labs/pkg.pr.new/pull/525) adds a
built-in `--previewVersion` flag (still open). If it lands we can drop
the version-rewrite half of the script, but we'd keep a pre-build stamp
anyway so `updateVersion.ts` picks up the preview version (the flag
rewrites at pack time, too late for the baked `VERSION`).
## Summary
Adds `drainBatchSize` to `MollifierDrainer` (default `1` — preserves
existing behaviour) and wires `TRIGGER_MOLLIFIER_DRAIN_BATCH_SIZE`
through the webapp (default `50`). Each tick the drainer now pops up to
`drainBatchSize` from each chosen env, then dispatches every popped
entry through the shared `concurrency`-bounded `pLimit`. Per-org/per-env
fairness is unchanged — only the in-env pop count grows.
Pre-existing behaviour was one pop per env per tick. For a single-env
burst that single-flighted the drain at the per-tick floor of `pop +
engine.trigger ≈ 50–60 ms`. With buffer entries piling up under a
real-world tenant burst that's tens of minutes of tail latency to fully
materialise — even though PG itself could comfortably sustain the
writes.
## Why this matters — heavy-tail illustration
Scenario: 100 customers in one window — 94 fire 20 triggers each, 5 fire
100, 1 fires 1000. Gate at `THRESHOLD=10/s`, `HOLD_MS=500`. First 10 of
each burst hit PG directly; the rest buffer.
| Customers | Triggers each | PG direct | Buffered each | Total buffered
|
|---|---|---|---|---|
| 94 small | 20 | 10 | 10 | 940 |
| 5 medium | 100 | 10 | 90 | 450 |
| 1 heavy | 1000 | 10 | 990 | 990 |
**With `DRAIN_BATCH_SIZE=50`, `DRAIN_CONCURRENCY=50`, ~50 ms
`engine.trigger`:**
| Tick | Pops | Dispatch waves | Wall-clock |
|---|---|---|---|
| 1 | 94×10 + 5×50 + 1×50 = 1 240 | 25 × 50 ms | ~1 300 ms (94 smalls
done) |
| 2 | 5×40 + 1×50 = 250 | 5 × 50 ms | ~300 ms (5 mediums done) |
| 3–20 | heavy alone, 50/tick | 1 × 50 ms | ~100 ms each |
| Customer class | Buffered fully drained |
|---|---|
| 94 small | **~1.3 s** |
| 5 medium | **~1.6 s** |
| 1 heavy | **~3.4 s** |
**Without batching (one pop per env per tick — current behaviour):**
| Customer class | Buffered fully drained |
|---|---|
| 94 small | ~500 ms |
| 5 medium | ~4.5 s |
| 1 heavy | **~49 s** |
So the heavy single-tenant tail drops from ~49 s to ~3.4 s (~14× faster)
without changing PG load characteristics. Smalls go up slightly in this
scenario (500 ms → 1.3 s) because all 100 envs share one tick's dispatch
queue — that's the trade we accept for the heavy tail; the worst-case
small wait is still inside one tick. PG load is identical either way (50
concurrent inserts at a time, capped by `DRAIN_CONCURRENCY`).
## What changed
**`packages/redis-worker`**
- New `drainBatchSize` option (default 1 — full backward compat).
- `runOnce()` refactored to pop per-env batches in parallel, then
dispatch all popped entries through the existing global `pLimit`.
Mid-batch pop failure aborts only that env's batch and counts as one
failure (same semantic as the old per-env path).
- Removed the now-unused `processOneFromEnv` helper.
**`apps/webapp`**
- `TRIGGER_MOLLIFIER_DRAIN_BATCH_SIZE` env var (default 50, matching
`DRAIN_CONCURRENCY`).
- Wired into `mollifierDrainer.server.ts`.
**Test cloud config** (separate cloud PR):
`TRIGGER_MOLLIFIER_DRAIN_BATCH_SIZE="50"` on the worker service.
Production rollout deferred until we've watched it on test cloud.
## Test plan
- [x] All 25 stub-based drainer tests pass (18 pre-existing + 7 new). 7
new tests under `MollifierDrainer.drainBatchSize`:
- pops up to `drainBatchSize` across ticks
- global `concurrency` cap still holds when batch > concurrency
- mid-batch pop failure isolation
- multi-env batch fan-out in one tick
- **hierarchical org fairness preserved at `drainBatchSize > 1`**
(load-bearing — guards against future regressions to
per-env-instead-of-per-org rotation)
- mixed success/failure accounting in a batched tick
- bounded pops on empty queue (no Lua spam past `drainBatchSize`)
- [x] All pre-existing tests still pass unchanged at default
`drainBatchSize=1` → backward-compat locked.
- [x] `pnpm run build --filter @trigger.dev/redis-worker` clean.
- [x] `pnpm run typecheck --filter webapp` clean.
- [x] `redisTest` block (real Redis via testcontainers) — couldn't run
locally on this branch due to testcontainers runtime discovery; will
validate in CI.
- [ ] Test-cloud smoke after cloud PR lands: fire `burst 50` against a
flagged env and confirm the 50th entry's drain time drops from ~2.5 s to
<200 ms.
## Notes
- Per-tick memory bound: `maxOrgsPerTick × drainBatchSize` entries can
sit in the JS pLimit queue between pop and dispatch. At defaults that's
`500 × 50 = 25 000` × ~5 KB snapshot ≈ ~125 MB worst case per worker —
well within headroom.
- The pre-batch model's strict per-env throughput cap of `1/tick` is
documented as the fairness baseline elsewhere. Org-level fairness is
what callers actually rely on; this change does not weaken that.

## Summary
Documents the new `tools` option on `chat.agent` (companion to #3790).
Adds a dedicated [Tools](/ai-chat/tools) guide: the three places tools
show up (config, `toStreamTextOptions`, `streamText`), why declaring
them on the config matters for `toModelOutput` across turns, static vs
per-turn tools, the typed `run()` payload,
`InferChatUIMessageFromTools`, the relationship to skills, and the
manual `convertToModelMessages` path for `customAgent` loops.
Threads the option through the rest of the guide: the reference tables,
a happy-path section on the backend page, the types page, and the HITL /
skills / tool-result-auditing patterns. Corrects the sub-agents guide,
where the `toModelOutput` compression was implied to work across turns
but silently degraded from turn 2 without config tools.
Also unstacks the three callouts that were piled under the
`chat.agent()` header on the backend page, and adds a changelog entry.
## Summary
1 new feature, 5 improvements.
## Highlights
- Mollifier `mutateSnapshot` now enforces a tag cap: an `append_tags`
patch carrying `maxTags` returns `"limit_exceeded"` (writing nothing)
when the deduped tag count would exceed the limit, so a buffered run
can't accumulate more tags via the tags API than the trigger validator
allows at creation.
([#3756](https://github.com/triggerdotdev/trigger.dev/pull/3756))
## Improvements
- Mollifier buffer extensions: idempotency dedup, an atomic
`mutateSnapshot` API, metadata CAS, claim primitives, and a
`MollifierSnapshot` type. The buffer's Redis client now reconnects with
jittered backoff so a fleet of clients doesn't stampede Redis in
lockstep after a blip.
([#3752](https://github.com/triggerdotdev/trigger.dev/pull/3752))
- Add `onTerminalFailure` callback to `MollifierDrainerOptions` so the
customer's run lands a SYSTEM_FAILURE PG row even when the drainer
exhausts `maxAttempts` on a retryable PG error. Previously,
retryable-error exhaustion called `buffer.fail()` directly, which
atomically marks FAILED + DELs the entry hash with no PG write — silent
data loss when PG was unreachable across the full retry budget. The
callback fires before `buffer.fail()` on any terminal path (`cause:
"non-retryable"` or `"max-attempts-exhausted"`); throwing a retryable
error from the callback causes the drainer to requeue rather than fail.
([#3754](https://github.com/triggerdotdev/trigger.dev/pull/3754))
- Bump `@s2-dev/streamstore` to `0.22.10` to fix a
`TASK_RUN_UNCAUGHT_EXCEPTION` ("Invalid state: Unable to enqueue") when
a `chat.agent` turn is aborted mid-stream.
([#3792](https://github.com/triggerdotdev/trigger.dev/pull/3792))
- Coerce numeric `concurrencyKey` values to string at the API boundary
across `tasks.trigger`, `tasks.batchTrigger`, and the Phase-2 streaming
batch endpoint.
([#3789](https://github.com/triggerdotdev/trigger.dev/pull/3789))
- Add a `tools` option to `chat.agent`. Declaring your tools here
threads them into the SDK's internal `convertToModelMessages`, so each
tool's `toModelOutput` is re-applied when prior-turn history is
re-converted.

# Releases
## @trigger.dev/redis-worker@4.5.0-rc.4
### Minor Changes
- Mollifier buffer extensions: idempotency dedup, an atomic
`mutateSnapshot` API, metadata CAS, claim primitives, and a
`MollifierSnapshot` type. The buffer's Redis client now reconnects with
jittered backoff so a fleet of clients doesn't stampede Redis in
lockstep after a blip.
([#3752](https://github.com/triggerdotdev/trigger.dev/pull/3752))
- Add `onTerminalFailure` callback to `MollifierDrainerOptions` so the
customer's run lands a SYSTEM_FAILURE PG row even when the drainer
exhausts `maxAttempts` on a retryable PG error. Previously,
retryable-error exhaustion called `buffer.fail()` directly, which
atomically marks FAILED + DELs the entry hash with no PG write — silent
data loss when PG was unreachable across the full retry budget. The
callback fires before `buffer.fail()` on any terminal path (`cause:
"non-retryable"` or `"max-attempts-exhausted"`); throwing a retryable
error from the callback causes the drainer to requeue rather than fail.
([#3754](https://github.com/triggerdotdev/trigger.dev/pull/3754))
### Patch Changes
- Pipeline the per-entry `HGETALL` fetches in
`MollifierBuffer.listEntriesForEnv`. The previous serial implementation
issued one Redis round-trip per runId returned by `LRANGE`, which
dominated stale-sweep wall-time at any meaningful backlog (at the
sweep's default maxCount=1000, this is ~1000 RTTs per env per pass).
Behaviour is unchanged — entries are still skipped when the entry hash
has been torn down by a concurrent drainer ack/fail between the LRANGE
and the HGETALL.
([#3752](https://github.com/triggerdotdev/trigger.dev/pull/3752))
- Mollifier `mutateSnapshot` now enforces a tag cap: an `append_tags`

Follow-up to #3796, which bumped the slack-client axios paths but left
posthog-node's transitive `axios@1.15.1` in place.
`posthog-node` 4.17.1 → 5.35.6. v5 drops the axios dependency entirely
(it's now fetch-based via `@posthog/core`), so posthog's old axios path
disappears. With #3796 already on main (webapp + d3 references on
`@slack/web-api@7.16.0`), nothing else pins the old line, so the
now-dead `axios@>=1.0.0 <1.15.0` override is removed and axios resolves
to a single patched `1.16.1` repo-wide. This closes the remaining axios
advisories.
Compat: the webapp's usage in `telemetry.server.ts` (`new PostHog(key, {
host })`, `.identify`, `.groupIdentify`, `.capture`) is all object-form
API that v5 preserves; `pnpm run typecheck --filter webapp` passes.
Node: posthog-node v5 requires Node `^20.20.0 || >=22.22.0`. We run
20.20.0 in dev (`.nvmrc`), CI, and the published Docker image
(`node:20.20-bullseye-slim`), so we're compliant.
Bumps `@slack/web-api` 7.9.1 → 7.16.0 in the webapp and the two
`references` examples (d3-chat, d3-openai-agents). 7.16.0 depends on
`axios@^1.16.0`, so every slack-client axios path resolves to 1.16.1
instead of 1.15.1.
This clears the slack and references axios paths. `posthog-node`'s
transitive axios still resolves the older line - that's handled in a
follow-up that upgrades posthog-node to v5 (which drops the axios
dependency entirely and lets us retire the now-stale axios override).
The dependabot axios advisories fully close once both land.
## Summary
A `chat.agent` turn that gets aborted mid-stream (stop generation, idle
suspend, cancellation) could surface a `TASK_RUN_UNCAUGHT_EXCEPTION` —
`TypeError: Invalid state: Unable to enqueue` — in the dashboard. The
run kept working, but the exceptions were loud and confusing.
## Root cause
The realtime stream writer batches chunks through
`@s2-dev/streamstore`'s `BatchTransform`, which holds them for a short
linger window before flushing. When the turn's abort signal fires while
a record is still buffered, the stream's writable is aborted and the
transform's readable controller is closed — but the pending linger
`setTimeout` still fires and calls `controller.enqueue()` on the dead
controller, throwing from a timer callback where nothing can catch it.
Fixed upstream in `@s2-dev/streamstore@0.22.10`, which wraps the linger
flush in a try/catch that discards the closed-controller error. This
bumps the dependency across core, the CLI, and the webapp, and adds a
regression test against the real `BatchTransform`.
Verified end-to-end: a mid-stream stop that previously failed the run
with `TASK_RUN_UNCAUGHT_EXCEPTION` now leaves the run healthy.
## Summary
`chat.agent` now takes a `tools` option. Until now tools only went to
`streamText` inside `run()`, so the SDK had no tools when it
re-converted the persisted `UIMessage` history at the start of each
turn. Any tool with a `toModelOutput` (raw image bytes into an image
content part, or a sub-agent transcript compressed to a summary) had its
transform applied on turn 1 and skipped from turn 2 onward, so the raw
output got JSON-stringified back into the prompt and the model lost the
transformed view.
Declaring `tools` on the config threads them into that conversion, so
`toModelOutput` runs on every turn. The resolved set is handed back,
typed, on the `run()` payload as `tools`:
```ts
const tools = { searchDocs, renderChart };
export const myChat = chat.agent({
tools,
run: async ({ messages, tools, signal }) =>
streamText({ ...chat.toStreamTextOptions({ tools }), messages, abortSignal: signal }),
});
```
`tools` also accepts a per-turn function for tools that depend on the
user or a feature flag. Only `inputSchema` and `toModelOutput` are read
during conversion, never `execute`. Also exports
`InferChatUIMessageFromTools<typeof tools>` to derive the chat
`UIMessage` type from a tool set. No behavior change for agents that
don't declare `tools`.
## Summary
Dashboard surfaces handle buffered runs by falling back to the mollifier
snapshot:
- Run detail, span detail, streams view (`_app.../runs.\$runParam`,
`resources.../spans.\$spanParam`, `resources.../streams.\$streamKey`).
- Redirect routes (`@.runs.\$runParam`, `runs.\$runParam`,
`projects.v3.\$projectRef.runs.\$runParam`).
- Action routes — cancel / replay / idempotency-reset / debug — under
`resources.taskruns/...` and `resources.../idempotencyKey.reset`.
- Logs download.
- Realtime subscription route + per-run resource
(`realtime.v1.runs.\$runId`, `resources.../realtime.v1.*`).
- `CancelRunDialog` gains an `onCancelSubmitted` callback so submit
isn't raced by the Radix `DialogClose` wrapper.

## Ship-gate follow-up fixes
- **Auto-redirect to root span on direct nav** — loader sets `?span=`
from root span (PG) or buffered snapshot spanId before 302'ing, so
bookmark/share-link/direct-nav doesn't leave the panel collapsed.
- **RunPresenter switches from `findFirstOrThrow` to `findFirst` + typed
`RunNotInPgError`** — kills the per-poll `PrismaClient error` log spam
for buffered runs without changing the route-loader's fallback flow.
- **Span detail panel renders for buffered runs** — `SpanPresenter.call`
now falls back to `findRunByIdWithMollifierFallback` +
`buildSyntheticSpanRun` instead of returning undefined and triggering
the "Event not found" toast loop.
- **Logs download for buffered runs returns a gzipped placeholder line**
— replaces the 404 with a content-encoded line explaining the run is
queued. Same org-membership gate as the PG path.
- **Admin Debug-Run button hidden for buffered runs + SpanRun circular
type alias broken** (squashed) — buttons gate on a new `isBuffered` flag
on the synthetic SpanRun. Required grounding SpanRun in
`SpanPresenter.getRun` to break a circular type alias TS no longer
tolerates once `isBuffered` is a literal field on the shape.
- **Replay action requires user auth + org-membership** (🚩 Devin
finding) — `action` was unauthenticated and the PG `findFirst` had no
org filter, so any caller with a valid `runParam` could replay any run.
Buffered fallback inherited the same gap. Fixed to mirror the cancel
route.

## Summary
Cancel, replay, reschedule, metadata, tags, and idempotency-key-reset
now succeed against a run that's still in the mollifier buffer.
Mutations are applied to the buffered snapshot via Lua CAS; the drainer
carries the mutation forward when it replays.
Primitives added:
- `mutateWithFallback` — PG-first / buffer-fallback resolver with
bounded-wait safety net for entries that transition mid-mutation.
- `applyMetadataMutation` — buffered metadata PUT mirroring the PG-side
retry loop with CAS atomicity.
- `resolveRunForMutation` — discriminated-union resolver used by route
`findResource` so the route builder's pre-action 404 check sees buffered
runs.
Routes wired (whole files, no GET/POST splits):
- `api.v2.runs.\$runParam.cancel.ts`
- `api.v1.runs.\$runParam.replay.ts`
- `api.v1.runs.\$runParam.reschedule.ts`
- `api.v1.runs.\$runId.metadata.ts`
- `api.v1.runs.\$runId.tags.ts`

## Summary
Synthesise QUEUED/FAILED responses from the mollifier buffer when a
TaskRun row hasn't landed in Postgres yet. Wires the synthesis into:
- `ApiRetrieveRunPresenter`
- v1 trace GET route
- v1 spans GET route
- attempts route gains a GET loader (fixes pre-existing Remix "no
loader" 400)
The `readFallback` infra itself lives on the trigger PR (consumed by
`IdempotencyKeyConcern`); this PR adds the route-level
synthetic-rendering primitives.

## Summary
The replay side of the mollifier:
- `DrainerHandler`: reads buffered snapshots and replays them through
`engine.trigger` to materialise PG rows.
- `RunEngine.createCancelledRun`: new public method the handler uses to
write CANCELED rows directly from snapshots (bypass queue + waitpoint,
emit `runCancelled`). Tolerates the cjson empty-table tags edge case
found during validation.
- Drainer fairness: org → env rotation so a heavy env doesn't starve
light ones in the same org.
- Stale-entry sweep + telemetry + alertable gauge so a stuck/offline
drainer surfaces in alerts.
Both the drainer and sweep default-off; nothing fires unless flagged on
(`TRIGGER_MOLLIFIER_DRAINER_ENABLED`,
`TRIGGER_MOLLIFIER_STALE_SWEEP_ENABLED`).

## Ship-gate follow-up fix
**Drainer writes SYSTEM_FAILURE on max-attempts exhaustion.** Adds an
`onTerminalFailure` callback on `MollifierDrainerOptions` so the
customer's run lands a SYSTEM_FAILURE PG row even when the drainer
exhausts `MAX_ATTEMPTS` on a retryable PG error (previously
`buffer.fail()` was called with no row written → silent data loss). The
callback runs before `buffer.fail()` on every terminal path
(non-retryable AND max-attempts-exhausted), and re-throwing a retryable
error from the callback causes the drainer to requeue rather than fail.
Bumps `@trigger.dev/redis-worker` to a **minor** changeset (additive
option + new exported types). Includes 5 unit tests covering both
terminal causes plus the requeue-on-retryable-callback-failure path and
no-callback back-compat.

## Summary
`concurrencyKey` validation accepted only `z.string().optional()` on the
single-trigger and V2/V3 batch endpoints, and the Phase-2 streaming
NDJSON endpoint accepted `z.record(z.unknown()).optional()` for the
entire `options` field. Callers passing `concurrencyKey: someNumericId`
(e.g. `payload.userId`) either failed schema validation on the first two
paths or sailed through on Phase-2 and then failed downstream at
`prisma.taskRun.create` with `Argument concurrencyKey: Expected String
or Null, provided Int`.
The schema now accepts `string | number` for `concurrencyKey` and
stringifies on the way in, across all three paths. The Phase-2 NDJSON
`options` is tightened to reuse the strict
`BatchTriggerTaskItem.options` shape so it validates identically to the
V2/V3 batch endpoints.
A defensive `typeof === "number"` coercion at the `engine.trigger` call
site in `RunEngineTriggerTaskService` covers in-flight Redis-stored
batch items enqueued before the schema fix — those items are rebuilt
from a `Record<string, unknown>` shape that bypasses the new schema and
would otherwise continue failing for up to their TTL.
## Test plan
- [x] `packages/core/src/v3/schemas/batchItemNDJSON.test.ts` — unit
tests covering numeric→string coercion, string passthrough, no-options,
and rejection of non-string/non-number shapes across
`TriggerTaskRequestBody`, `BatchTriggerTaskItem`, and `BatchItemNDJSON`.
- [x] `apps/webapp/test/engine/triggerTask.test.ts` — `containerTest`
simulating the in-flight Redis batch-item shape (numeric
`concurrencyKey` via `Record<string, unknown>`), verifies the run is
created with `concurrencyKey: "51262"`. Without the worker coercion, the
test reproduces the production stack at `prisma.taskRun.create`.
- [x] `pnpm run typecheck --filter webapp` clean.
- [x] `pnpm run build --filter @trigger.dev/core --filter
@trigger.dev/sdk --filter trigger.dev` clean.

## Summary
The trigger hot path's mollifier integration:
- `mollifyTrigger`: when the gate trips, write the engine.trigger
snapshot to the buffer and return a synthesised QUEUED response.
Postgres write is deferred to drainer-replay (next PR in the stack).
- Pre-gate idempotency-key claim: same-key triggers serialise through
Redis so a burst lands in PG / buffer exactly once.
- Read-fallback extensions: `findRunByIdWithMollifierFallback` for the
trigger-time idempotency lookup that must see buffered runs.
- Gate bypasses: `debounce`, `oneTimeUseToken`,
`parentTaskRunId`/`triggerAndWait` skip the mollify path entirely.
- `triggerTask` + `IdempotencyKeyConcern` wired to the above.
All behaviour gated by the master `TRIGGER_MOLLIFIER_ENABLED` switch;
off-state hot path is unchanged (the gate is not even consulted).

create-on-materialise; batch traffic passes through the gate until that
lands.
- **IdempotencyKeyConcern honours buffered-run TTL on expiry** —
buffered path now clears expired idempotency claims (read-side) and
resets the buffer's `mollifier:idempotency:*` SETNX binding (write-side)
so a re-trigger past the customer's TTL lands as a fresh run instead of
echoing the stale buffered runId.

## Summary
Buffer-side data layer used by the rest of the mollifier phase-3 stack.
- `buffer.ts` gains entry inspection (`getEntry`), idempotency lookup
(`lookupIdempotency`), in-place snapshot mutation (`mutateSnapshot`),
and dwell tracking. All atomic via Lua.
- `mollifierSnapshot.server.ts`: shared `MollifierSnapshot` type plus
(de)serialise helpers.
- Drops the entry-TTL config and its env var. The drainer is the
recovery mechanism; an entry that survives the drainer should surface as
a stale-sweep alert, not silently TTL away.
Adds methods to the buffer interface; nothing consumes them yet.
Subsequent PRs in the stack wire trigger-time mollify, read-fallback,
and mutation paths against this surface.
## Test plan
- [x] \`pnpm run typecheck --filter webapp\` passes
- [x] \`pnpm run test --filter @trigger.dev/redis-worker
packages/redis-worker/src/mollifier/buffer.test.ts\` passes

## Summary
1 improvement, 2 bug fixes.
## Improvements
- Retry `TASK_MIDDLEWARE_ERROR` under the task's retry policy instead of
failing the run on the first attempt. The error was already classified
as retryable by `shouldRetryError`, but `shouldLookupRetrySettings` did
not include it, so the retry flow fell through to `fail_run`. Fixes
#3231. ([#3676](https://github.com/triggerdotdev/trigger.dev/pull/3676))
## Bug fixes
- Fix `TypeError` in `unflattenAttributes` when the input attribute map
contains conflicting dotted key paths (e.g. both `a.b` set to a scalar
and `a.b.c` set to a value). The path-walk loop now applies
last-write-wins when a prior key wrote a primitive, null, or array at an
intermediate slot, matching the existing precedent in
`AttributeFlattener.addAttribute`. Callers no longer crash when handed
malformed external attribute inputs.
([#3762](https://github.com/triggerdotdev/trigger.dev/pull/3762))
- Fix external trace context leaking across runs on warm-started workers
with `processKeepAlive` enabled. Every subsequent run's attempt span was
being exported with the first run's `traceId` and `parentSpanId`,
breaking causal-chain navigation in external APM tools. Runs without an
external trace context are unaffected.

## Summary
Drops the `TaskRun_status_runtimeEnvironmentId_createdAt_id_idx` index
from the `TaskRun` table. After #3742 gated the legacy
`WAITING_FOR_DEPLOY` drain to V1-engine workers only, this index sees
zero scans on both writer and reader replicas. Removing it cuts index
maintenance on every `TaskRun` INSERT/UPDATE.
## Why
The index existed to support `WHERE status = X AND runtimeEnvironmentId
= Y` queries from `ExecuteTasksWaitingForDeployService`, which is
V1-only and no longer triggered on V2 deployments. A code grep across
`apps/webapp` and `internal-packages/run-engine` confirmed no V2
production query uses this access pattern — every other `status:` filter
on `TaskRun` is paired with `id`/`friendlyId`/`parentSpanId` and uses a
different index.
Dropping it also unlocks HOT updates on the dequeue path. The dequeue
`UPDATE` modifies `status` (`QUEUED` -> `DEQUEUED`), and `status` is the
leading column of this index — its presence blocked HOT eligibility for
every `TaskRun` UPDATE. With the index gone, dequeue UPDATEs can become
HOT, reducing WAL bytes and removing the B-tree page contention on this
index's right-edge leaves.
Uses `DROP INDEX CONCURRENTLY` to avoid blocking writes during the drop.
## Sequencing
Should only ship once #3742 has soaked long enough to confirm the index
is genuinely cold (24h+ of zero scans on `pg_stat_user_indexes`).
Make `POST /api/v1/deployments/:deploymentId/background-workers`
idempotent so client-side retries no longer collide on the
`BackgroundWorker` `(project, env, version)` unique index. Helps make
deployments more resilient against the class of indexing failures that
surfaces in the dashboard as "Indexing timed out", e.g. during transient
database issues.
On warm-started workers with `processKeepAlive` enabled, every run's
attempt span was exported with the first run's `traceId` and
`parentSpanId`. `ExternalSpanExporterWrapper` and
`ExternalLogRecordExporterWrapper` captured `externalTraceContext` at
`TracingSDK` construction, and the SDK is memoized for the worker's
lifetime - so the per-run reset of
`StandardTraceContextManager.traceContext` never reached the wrappers.
Reported by a customer running v4.4.x: 33 distinct runs on the same
host/pid showed up in their APM as siblings of one parent span.
Fix: the wrappers now read external context live from the trace context
manager per export. Runs without an external trace context fall through
to the unchanged `externalTraceId` fallback - no behaviour change for
them.
Regression test in
`packages/core/test/externalSpanExporterWrapper.test.ts` asserts that
reassigning the manager between exports produces correctly-parented
spans.
Retries `TASK_MIDDLEWARE_ERROR` under the task's retry policy.
`shouldRetryError` already classed it as retryable, but
`shouldLookupRetrySettings` did not, so the run fell through to
`fail_run` on attempt 1 instead of using the task's `retry` config.
Fixes#3231.
## Summary
Second class of poisoned-row failure in the runs replication path. PR
#3708 plugged lone UTF-16 surrogates; this one handles bare JSON integer
literals outside ClickHouse's `Int64`..`UInt64` range. Recovery stays
purely reactive — the existing `sanitizeRows` walker just gains an extra
branch, so the hot replication path pays nothing on healthy rows.
Fixes the still-firing customer-facing symptom from
[TRI-9755](https://linear.app/triggerdotdev/issue/TRI-9755):
`scan-social-profiles` runs continued to be stranded in `EXECUTING` on
the Tasks page after #3708 deployed. CloudWatch showed `Dropped batch —
ClickHouse JSON parse error but sanitizer found nothing to fix` firing
**8/8 times** since the previous deploy (zero successful sanitizations).
Root cause: upstream JS Number precision loss on a 21-digit Google Plus
ID (`117039831458782873093` → `117039831458782870000`) — the
precision-lossy value still serialises as a bare integer that exceeds
`UInt64.MAX`, which ClickHouse rejects with `INCORRECT_DATA`.
## How the bug ships
The customer task emits an output containing a Poshmark profile's
`spec_format`:
```json
{"key":"gp_id","proper_key":"Gp Id","value":117039831458782870000,"type":"int"}
```
That value is `1.17e20` — comfortably above `UInt64.MAX` (`1.84e19`) but
comfortably below `1e21`. `Number.prototype.toString` only switches to
exponential form at `|value| >= 1e21`, so `JSON.stringify` emits the
bare token `117039831458782870000` and the ClickHouse
`JSON(max_dynamic_paths)` column fails with:
```
Code: 117. DB::Exception: Cannot parse JSON object here: {…}: (while reading the value of key output): (at row 1)
: While executing ParallelParsingBlockInputFormat. (INCORRECT_DATA) (version 25.12.x)
```
Same error verbatim as prod. The same number quoted
(`"117039831458782870000"`) inserts fine — ClickHouse's dynamic JSON
column accepts a `String` subtype on the same path.
## What changed
`apps/webapp/app/v3/eventRepository/sanitizeRowsOnParseError.server.ts`:
- New private `isUnsafeJsonInteger(value)` helper — true iff `value` is
a finite integer-valued JS Number where `|value| < 1e21` (so
`JSON.stringify` emits integer form, not exponent) **and** `value` falls
outside `[Int64.MIN, UInt64.MAX]`.
- `sanitizeUnknownInPlace` gains a number-branch: when the predicate
holds, replace the Number with `String(value)`. The downstream JSON
column dynamic-types the path as String for that row — fine, since the
value was already precision-lossy upstream (no JS Number above 2^53 is
numerically meaningful anyway).
- Float-valued numbers, large floats (>= 1e21), NaN and Infinity are
left alone — `JSON.stringify` emits them with exponents or as `null`,
both of which ClickHouse accepts.
`apps/webapp/test/sanitizeRowsOnParseError.test.ts`: four new unit tests
+ an extension to `sanitizeRows` covering surrogate + integer fixes
counted together across rows. The unit suite now covers:
- Positive value above `UInt64.MAX` (`117039831458782870000` — the
actual prod value)
- Negative value below `Int64.MIN`
- Boundary values pass through (`42`, `Number.MAX_SAFE_INTEGER`, `2^63`)
- Non-integer numbers untouched (floats, `1e25`, NaN, Infinity)
- The actual `scan-social-profiles` nested shape — finds the offending
`gp_id` deep inside
`output.data.profiles[].spec_format[].platform_variables[].value`
`.server-changes/runs-replication-bigint-recovery.md` — release notes
entry.
## Why reactive, not pre-flight
`#prepareJson` runs millions of times per day on the replication hot
path. Walking every JSON tree to look for oversized integers would add
bounded-but-real CPU on every healthy row. `sanitizeRows` only fires
after a ClickHouse parse-error rejection, which is a few times a day
platform-wide. Extending it costs effectively zero on healthy traffic
and gains us recovery on the rare poisoned row.
## Verification
- Reproduced 1:1 in a throwaway Docker
`clickhouse/clickhouse-server:25.12.11.4` (closest available to the prod
`25.12.1.1579` build). Pre-sanitize JSON fails with the exact prod
error; post-sanitize JSON inserts cleanly and the row is readable with
`gp_id` stored as a String subtype.
- `pnpm --filter webapp exec vitest run
test/sanitizeRowsOnParseError.test.ts` — 22/22 passing (18 existing + 4
new).
- `pnpm run typecheck --filter webapp` — clean.
## Test plan
- [x] `pnpm run typecheck --filter webapp`
- [x] Unit tests pass against new + existing cases
- [x] End-to-end Docker ClickHouse repro confirms recovery
- [ ] Post-deploy: confirm `Sanitizing batch after ClickHouse JSON parse
error` warns fire instead of `Dropped batch …` errors when
`scan-social-profiles` outputs trip CH again
- [ ] Post-deploy: confirm `permanentlyDroppedBatches` counter stops
climbing in
`/stp/trigger-app-prod/ecs/replication/service-container/process-logs`
## What this does NOT do
- Doesn't backfill the ~120k+ existing stranded `EXECUTING` rows in
production. Same as #3708 — that needs a reconciliation/backfill sweep
(separate ticket — TRI-9755 fix#3).
- Doesn't address the upstream root cause (the customer task emitting a
JS-Number-precision-lossy big int). That's a customer-task concern; our
replication path needs to be robust to whatever shape arrives.

## Summary
Stops the legacy V1 `WAITING_FOR_DEPLOY` drain from running on every V2
deployment promotion. The drain queries `TaskRun` by
`status='WAITING_FOR_DEPLOY'`, which only V1-engine runs ever have — V2
runs use `PENDING_VERSION` and are handled out of band. Calling the
drain on V2 promotes produced empty queries against the status index and
unnecessary reader-DB load.
## Fix
Two layers:
1. Gate the enqueue at the call site in `ChangeCurrentDeploymentService`
so it only fires when the deployment's worker is on engine V1.
2. Add a `LEGACY_RUN_ENGINE_WAITING_FOR_DEPLOY_DISABLED` env var
(default `0`). When set to `1`, the service returns immediately from
`call()` — neuters any jobs already sitting in the worker queue from
before the deploy lands.
V1 customers see no change; V2 promotes no longer trigger the drain.
Linear: [TRI-9864](https://linear.app/triggerdotdev/issue/TRI-9864)
(Urgent)
Production incident:
[TRI-9863](https://linear.app/triggerdotdev/issue/TRI-9863) (mitigated
by image revert in cloud#910)
## Bug
`apps/webapp/package.json` declares `"sideEffects": false`. PR #3333
(`71d98b4e`) replaced the previous real method-call retention idiom at
the two `sessionsReplicationInstance` import sites with:
```ts
import { sessionsReplicationInstance } from "...";
void sessionsReplicationInstance;
```
esbuild treats `void <identifier>;` as a pure expression statement under
`sideEffects: false` and **tree-shakes the entire import** — including
the `singleton(...)` call inside `sessionsReplicationInstance.server.ts`
which is the only thing that fires
`initializeSessionsReplicationInstance()`. The sessions→ClickHouse
logical replication worker never starts, the slot is unconsumed, lag
grows.
### How it manifested in production
cloud#907's image bump rolled the `SessionReplicationService` ECS task
on prod at 14:32 UTC. The new container's startup log emitted `🗃️ Runs
replication service enabled` but **not** `🗃️ Sessions replication
service enabled` or `🗃️ Sessions replication service started`.
CloudWatch `OldestReplicationSlotLag` grew at ~220 MB/min and the `High
replication lag` alarm fired at 14:37 UTC. Prod was reverted to the
previous image (cloud#910) to stop the bleed.
### Verification
`grep` of the built bundle `apps/webapp/build/index.js` (built from
`c0365d36`):
- **3** occurrences of `Runs replication` / `runsReplicationInstance`
strings ✅
- **0** occurrences of `Sessions replication` /
`sessionsReplicationInstance` / `SessionsReplicationService` ❌
The runs path survives tree-shaking because `adminWorker.server.ts` and
`admin.api.v1.runs-replication.*` routes have real method calls
(`.start()`, `.teardown()`, `.backfill()`) — observable uses the
tree-shaker must preserve. The sessions singleton has no real callers,
only the `void` no-ops, hence its complete elimination from the bundle.
## Fix
Replace `void sessionsReplicationInstance;` with an assignment to
`globalThis`, an unambiguous observable side effect the bundler cannot
eliminate:
```ts
(globalThis as Record<string, unknown>).__sessionsReplicationInstance =
sessionsReplicationInstance;
```
Applied at both call sites: `apps/webapp/app/entry.server.tsx` and
`apps/webapp/app/v3/services/adminWorker.server.ts`.
Surrounding comments updated to document the bundler interaction so the
next maintainer doesn't reintroduce `void`.
## Out of scope (follow-ups)
- **Robustness improvement**: change `apps/webapp/package.json` from
`"sideEffects": false` to an allowlist that includes
`*Instance.server.ts` files. Prevents the same regression shape via any
future `*Instance` singleton.
- **Build-time check**: add a `grep` post-build step in `publish.yml`
requiring `"Sessions replication"` to appear in
`apps/webapp/build/index.js`. Catches this exact regression at CI time.
## Test plan
- [x] `pnpm run typecheck --filter webapp` clean
- [ ] After merge + publish: confirm new image's
`SessionReplicationService` container logs `🗃️ Sessions replication
service enabled` and `🗃️ Sessions replication service started` at
startup
- [ ] After re-deploying to prod: confirm `OldestReplicationSlotLag`
stops growing and drains
## Summary
On a ClickHouse `Cannot parse JSON object` rejection,
`RunsReplicationService` now sanitizes lone UTF-16 surrogates across the
failing batch via the existing `sanitizeRows` helper and retries once.
If the sanitizer found nothing or the retry also fails, the batch is
dropped loudly with a counter increment, so the surrounding
`#insertWithRetry` layer doesn't spin three more times on a
deterministic failure. Non-parse errors propagate unchanged.
Mirrors the pattern from #3659 (for `ClickhouseEventRepository`) — same
root cause (lone UTF-16 surrogates in user-provided JSON), same recovery
shape, **reusing the same shared helpers** (`sanitizeRows`,
`isClickHouseJsonParseError`, `parseRowNumberFromError`).
Fixes the customer-facing symptom from
[TRI-9755](https://linear.app/triggerdotdev/issue/TRI-9755): a single
row's poisoned `output` JSON used to take down the
`COMPLETED_SUCCESSFULLY` UPDATE events for its 50+ batch-mates,
stranding them in `EXECUTING` in ClickHouse forever and inflating
"Running" counts on the Tasks page. Confirmed in production this is
ongoing — ~120k stale rows accumulated in a single 5-hour burst on
2026-05-18; smaller continuous leak before and after.
## What changed
`apps/webapp/app/services/runsReplicationService.server.ts`:
- Imports the three helpers from
`~/v3/eventRepository/sanitizeRowsOnParseError.server` (no duplication;
no move).
- New private `#insertWithJsonParseRecovery<T>(rows, doInsert,
contextLabel, attempt)` — generic over `TaskRunInsertArray[]` and
`PayloadInsertArray[]`, structurally identical to
`ClickhouseEventRepository.#insertWithJsonParseRecovery`. Try → on parse
error sanitize the whole batch (the `at row N` hint is logged but not
used to slice — semantics under `input_format_parallel_parsing` aren't
stable) → retry once → drop with loud log if sanitizer found nothing OR
retry still fails.
- `#insertTaskRunInserts` and `#insertPayloadInserts` extract a
`doInsert` closure and hand it to the wrapper. Existing error logging,
span recording, and `recordSpanError` are preserved inside the closure.
- New `private _permanentlyDroppedBatches = 0` counter with a public
getter, for ops dashboards and tests (matches the events-repo
convention). One shared counter for both insert sites — granularity
comes from the `contextLabel` (`task_runs_v2` /
`raw_task_runs_payload_v1`) on every log line.
`.server-changes/runs-replication-utf16-recovery.md` — release notes
entry.
## Why no new tests
The shared helpers already have full unit + real-ClickHouse contract
coverage from #3659
(`apps/webapp/test/sanitizeRowsOnParseError.test.ts`,
`apps/webapp/test/otlpUtf16Sanitization.integration.test.ts`). The new
wrapper is a line-for-line structural port. Adding a parallel
integration test would require synthesizing bad data that *escapes* the
preemptive `detectBadJsonStrings` check in `#prepareJson` but still
trips ClickHouse — non-trivial without hand-crafted fixtures and
wouldn't cover any new logic.
## What this does NOT do
- Doesn't touch the ~120k existing stale `EXECUTING` rows in production.
That needs a reconciliation/backfill sweep (separate ticket — TRI-9755
fix#3).
- Doesn't sanitize the `error` column path
(`runsReplicationService.server.ts:932 const errorData = { data:
run.error };`). Reactive recovery will catch it if it ever poisons a
batch, but feeding it through `#prepareJson` like `output` is a cheap
follow-up.
## Test plan
- [x] `pnpm run typecheck --filter webapp` — clean
- [ ] Post-deploy: confirm `permanentlyDroppedBatches` counter stays at
zero (or near-zero) in
`/stp/trigger-app-prod/ecs/replication/service-container/process-logs`,
and watch for `Sanitizing batch after ClickHouse JSON parse error` warns
to confirm recovery is firing on real traffic
- [ ] Post-deploy: confirm the rate of new
"EXECUTING-but-actually-COMPLETED" zombies in ClickHouse flattens
(current rate ≈ tens-to-hundreds per hour platform-wide)

## Summary
Updates the AI chat docs to match the slim-wire + field-level merge
behavior shipped in #3719 and the precise `.in/append` cap +
CORS-readable 413 shipped in #3720. No behavior changes here — code is
correct in `main`; the docs were lagging on three patterns customers
copy out of the page.
## What changed
- **`hydrateMessages` examples upsert by id** (in `lifecycle-hooks.mdx`,
`patterns/database-persistence.mdx`, and
`patterns/persistence-and-replay.mdx`). The previous
`stored.push(newMsg)` pattern duplicated the assistant id on HITL
continuations and caused the LLM to receive a tool call with no
`arguments`. The new examples include the rationale inline.
- **`onValidateMessages` example filters to user messages**
(`lifecycle-hooks.mdx`). The previous example called
`validateUIMessages({ messages, tools })` directly, which now throws on
HITL slim wires (the AI SDK schema requires `input` on resolved tool
parts). New example shows the filter pattern, with a Warning callout
explaining why.
- **Merge contract description updated** (`lifecycle-hooks.mdx`). The
old wording said incoming messages are "auto-merged" / "replaced"; the
new description explains the actual field-level overlay (state advances
only).
- **Approval-responded wire example slimmed** (`client-protocol.mdx`).
Shows the minimum shape the agent reads — `state` + `approval` (or
`output` / `errorText` for HITL). Notes that the built-in transports
ship this slim shape by default and that fuller shapes are still
accepted.
- **`/in/append` 413 row and FAQ updated** (`client-protocol.mdx`,
`patterns/trusted-edge-signals.mdx`). Reflects the new precise S2 cap
and the CORS-readable 413.
- **New changelog entry** at the top of `changelog.mdx` covering all of
the above.
The historical `## 512 KiB ceiling removed` entry further down the
changelog is left as-is (it's a snapshot of the prior transition), and
the v4.5 upgrade-guide section is skipped — the merge contract is
backwards compatible.
## Test plan
- Mintlify dev preview renders cleanly with no broken anchors
- Linked references resolve (`/ai-chat/lifecycle-hooks#hydratemessages`,
`/ai-chat/lifecycle-hooks#onvalidatemessages`,
`/ai-chat/patterns/database-persistence#alternative-hydratemessages`,
`/ai-chat/client-protocol#step-3-send-messages-stops-and-actions`,
`/ai-chat/patterns/large-payloads`)
## Summary
3 improvements, 1 bug fix.
## Improvements
- The per-turn merge now overlays the wire copy's tool-part state
advancement onto the agent's existing chain — `state` + the matching
resolution field (`output` / `errorText` / `approval`) come from the
wire, everything else (text, reasoning, tool `input`, provider metadata)
stays whatever the snapshot or `hydrateMessages` returned. Previously a
full-message replace overwrote those fields with whatever the client
shipped, so a slimmed wire copy landed a tool call with no `arguments`
on the next LLM call. Covers `output-available` / `output-error` (HITL
`addToolOutput`) and `approval-responded` / `output-denied` (approval
flow).
- `TriggerChatTransport.sendMessages` and `AgentChat.sendRaw` now slim
assistant messages that carry advanced tool parts. The wire payload is
just `{ id, role, parts: [<state + resolution field>] }` for
`submit-message` continuations; everything else passes through.
Reasoning blobs and full tool inputs no longer ride the wire on every
`addToolOutput` / `addToolApproveResponse`, so continuation payloads
stay well under the `.in/append` cap on long agent loops.
- Add `TriggerClient` for running multiple SDK clients side-by-side,
each with its own auth, preview branch, and baseURL. Useful when a
single process needs to trigger tasks or read runs across multiple
projects, environments, or preview branches without mutating shared
global state.

### Patch Changes
- Fix `chat.agent` HITL continuations on reasoning-heavy turns. Two
changes that work together:
([#3719](https://github.com/triggerdotdev/trigger.dev/pull/3719))
- The per-turn merge now overlays the wire copy's tool-part state
advancement onto the agent's existing chain — `state` + the matching
resolution field (`output` / `errorText` / `approval`) come from the
wire, everything else (text, reasoning, tool `input`, provider metadata)
stays whatever the snapshot or `hydrateMessages` returned. Previously a
full-message replace overwrote those fields with whatever the client
shipped, so a slimmed wire copy landed a tool call with no `arguments`
on the next LLM call. Covers `output-available` / `output-error` (HITL
`addToolOutput`) and `approval-responded` / `output-denied` (approval
flow).
- `TriggerChatTransport.sendMessages` and `AgentChat.sendRaw` now slim
assistant messages that carry advanced tool parts. The wire payload is
just `{ id, role, parts: [<state + resolution field>] }` for
`submit-message` continuations; everything else passes through.
Reasoning blobs and full tool inputs no longer ride the wire on every
`addToolOutput` / `addToolApproveResponse`, so continuation payloads
stay well under the `.in/append` cap on long agent loops.
Note: `onValidateMessages` receives the slim wire on HITL turns. If you
call `validateUIMessages` from `ai` against the full `messages` array it
will reject the slim assistant; filter to user messages (or skip on HITL
turns) — see the updated docstring on `onValidateMessages` for the
recommended pattern.
For `hydrateMessages` hooks that persist the chain, this release also
adds a small helper to the `@trigger.dev/sdk/ai` surface:
```ts
import { chat, upsertIncomingMessage } from "@trigger.dev/sdk/ai";
chat.agent({
hydrateMessages: async ({ chatId, trigger, incomingMessages }) => {
const record = await db.chat.findUnique({ where: { id: chatId } });
const stored = record?.messages ?? [];
if (upsertIncomingMessage(stored, { trigger, incomingMessages })) {
await db.chat.update({ where: { id: chatId }, data: { messages: stored }
});
}
return stored;
},
});
```
It pushes fresh user messages by id, no-ops on HITL continuations (the
incoming shares an id with the existing assistant — the runtime overlays
the new tool-state advance), and skips on non-`submit-message` triggers.
Returns `true` if it mutated `stored` so the caller knows whether to
persist.
Net effect: `chat.addToolOutput(...)` /
`chat.addToolApproveResponse(...)` on multi-step reasoning agents
(OpenAI Responses with `store: false`, Anthropic extended thinking,
etc.) no longer blows the cap and no longer corrupts the LLM input.
- Add `TriggerClient` for running multiple SDK clients side-by-side,
each with its own auth, preview branch, and baseURL. Useful when a
single process needs to trigger tasks or read runs across multiple
projects, environments, or preview branches without mutating shared
global state.
([#3683](https://github.com/triggerdotdev/trigger.dev/pull/3683))
```ts
import { TriggerClient } from "@trigger.dev/sdk";
const prod = new TriggerClient({ accessToken:
process.env.TRIGGER_PROD_KEY });
const preview = new TriggerClient({
accessToken: process.env.TRIGGER_PREVIEW_KEY,
previewBranch: "signup-flow",
});
await prod.tasks.trigger("send-email", payload);
await preview.runs.list({ status: ["COMPLETED"] });
```

## Summary
Multi-step reasoning agents with HITL tools (OpenAI Responses with
`store: false`, Anthropic extended thinking, etc.) failed on
`chat.addToolOutput(...)` continuations — either the wire payload blew
the `.in/append` cap (reasoning blobs + tool inputs routinely > 512
KiB), or app-side slimming workarounds got overwritten server-side and
the next LLM call landed a tool call with no `arguments`. Both modes are
fixed.
## Design
The per-turn merge in `chat.agent` now overlays only the tool-part state
advances (`output-available` / `output-error` / `approval-responded` /
`output-denied`) from the wire copy onto the hydrated/snapshot chain.
Previously it replaced the entire message, which dropped `input`,
reasoning, and text from the LLM's view whenever the wire was slim.
In parallel, `TriggerChatTransport.sendMessages` and `AgentChat.sendRaw`
now slim the assistant message themselves on `submit-message`
continuations: ship `{ id, role, parts: [<resolved tool part only>] }`,
everything else reconstructed server-side from `hydrateMessages` or the
durable snapshot. Continuation payloads drop from 600 KiB – 1 MiB to ~1
KiB.
`references/ai-chat` `aiChatHydrated.hydrateMessages` now upserts by id
instead of pushing. With slim continuations, a blind push duplicates the
assistant id in the returned chain — the merge updates the first match,
the slim duplicate goes straight to `toModelMessages` with no `input`,
and the LLM 4xx's. This is the canonical pattern customers should mirror
in their own hydrate implementations.
## Test plan
- 11 new tests (slim helper unit + slim+merge integration for HITL,
approval, default no-hydrate branch)
- Full SDK suite: 239 tests pass across 19 files
- End-to-end sweep against `references/ai-chat`: 19 customer-side smoke
tests green; HITL wire bodies confirmed at ~1 KiB (was 600 KiB+); no
provider 4xx errors across OpenAI Responses or Anthropic
## Summary
Two improvements to session `.in/append`:
- Oversize-body 413 responses now carry CORS headers, so browser fetches
see a readable status instead of an opaque `TypeError: Failed to fetch`.
App-side retry-on-disconnect loops no longer spin forever on a
permanently-rejected payload.
- The per-record cap is now computed precisely against S2's actual
ceiling instead of the conservative 512 KiB floor. Legitimate ~600-900
KiB tool outputs (search results, file content) now succeed;
pathological all-quote content that would double under JSON escape still
rejects cleanly.
## Design
S2 enforces a per-record metered size of `8 + 2*H + Σ(header name +
value) + body ≤ 1048576` bytes. With no record headers (our case), the
budget reduces to `body ≤ 1048568`. Verified empirically against cloud
S2 — append succeeds at metered=1048576 and 422s at 1048577 with `record
must have metered size less than 1 MiB`.
The old `MAX_APPEND_BODY_BYTES = 512 KiB` was derived by assuming
worst-case JSON escape doubling (every byte becomes `\"` or `\\`),
giving `(1 MiB - overhead) / 2`. Safe, but rejects ~half the legitimate
input space.
The new flow:
1. Pre-cap the HTTP body at 1 MiB (DoS guard against reading arbitrary
garbage before we can compute the wrap).
2. After reading, `S2RealtimeStreams.#appendPartByName` computes
`Buffer.byteLength(JSON.stringify({data: part, id: partId}), "utf8") +
8` and throws `S2RecordTooLargeError` (a `ServiceValidationError` with
status 413) if it would exceed S2's ceiling. The route's existing error
branch maps the throw to a 413 with a descriptive message.
The 413 CORS fix is a single-line change in `apiBuilder.server.ts` —
`wrapResponse` was being skipped on the body-too-large branch; every
other error branch wraps; the 413 was the exception.
## Test plan
- Empirically verified against cloud S2 with a boundary scan across
`[1048568, 1048569, ..., 1048576]` and across H ∈ {0, 1×5 hdr bytes,
1×14 hdr bytes} — the formula matches exactly
- Browser-side fetch on a 700 KiB POST now resolves with a readable
`status: 413` (no `TypeError: Failed to fetch`)
- A 900 KiB ASCII tool output now passes (would have 413'd at 512 KiB
pre-fix)
## Bug
The `OrganizationDataStoresRegistry` singleton in
`apps/webapp/app/services/dataStores/organizationDataStoresRegistryInstance.server.ts`
was constructed with `$replica`. That client was then used by both the
polling read path *and* by `addDataStore` / `updateDataStore` /
`deleteDataStore` (and their backing `SecretStore.setSecret` upserts).
The write methods route through the read replica, which Postgres rejects
with **error code 25006**:
```
Invalid prisma.secretStore.upsert() invocation:
ConnectorError(ConnectorError { user_facing_error: None, kind: QueryError(PostgresError {
code: "25006",
message: "cannot execute INSERT in a read-only transaction",
...
}), transient: false })
```
User-visible symptom: the admin `/admin/data-stores` "Add data store"
form returns a 400 with this error wrapped, so no
`OrganizationDataStore` row can ever be created via the UI.
The read path (`loadFromDatabase` polling + `SecretStore.getSecret`) is
unaffected because `findMany` + secret read are read-only.
## Fix
Change the registry constructor to take both a writer and a replica:
```ts
constructor(writer: PrismaClient, replica: PrismaClient | PrismaReplicaClient)
```
- `loadFromDatabase()` keeps using `_replica` (and its
`SecretStore.getSecret` calls) — these are background cache-fillers, not
on user-latency-sensitive paths.
- `addDataStore` / `updateDataStore` / `deleteDataStore` (and their
`SecretStore.setSecret` / `deleteSecret` calls) now use `_writer`.
`organizationDataStoresRegistryInstance.server.ts` passes `(prisma,
$replica)` from `~/db.server`. Test sites that constructed with
`(prisma)` now pass `(prisma, prisma)` — the testcontainer exposes a
single client, so the writer/replica split collapses to one connection.
## Files
-
`apps/webapp/app/services/dataStores/organizationDataStoresRegistry.server.ts`
— constructor + read/write split
-
`apps/webapp/app/services/dataStores/organizationDataStoresRegistryInstance.server.ts`
— pass `prisma` alongside `$replica`
- `apps/webapp/test/organizationDataStoresRegistry.test.ts` — 14 call
sites bumped
- `apps/webapp/test/clickhouseFactory.test.ts` — 5 call sites bumped
## Test plan
- [x] Existing `organizationDataStoresRegistry.test.ts` +
`clickhouseFactory.test.ts` still pass (constructor sites updated;
behavior unchanged for tests).
- [ ] After deploy to test cloud, retry `/admin/data-stores` "Add data
store" form for the HIPAA org — should now succeed and the row should
appear.
- [ ] Verify the registry's polling reload picks up the new row within
`ORGANIZATION_DATA_STORES_RELOAD_INTERVAL_MS` (60s default) and the
factory starts routing to the org-scoped instance.
## Summary
When a background worker registers, the engine resolves runs that were
queued before the worker was ready (status `PENDING_VERSION`). That
lookup used to scan a Postgres status index on `TaskRun`. Move it to
ClickHouse: query candidate run ids from `task_runs_v2`, then refetch
the actual rows from Postgres by primary key with a `status =
'PENDING_VERSION'` guard for idempotency.
## Design
The lookup is a pluggable interface on the run engine
(`PendingVersionRunIdLookup`). The webapp wires a ClickHouse-backed
implementation through the org-scoped `clickhouseFactory` using a new
`"engine"` client type, configured by `RUN_ENGINE_CLICKHOUSE_*` env
vars. The URL falls back to `CLICKHOUSE_URL` when unset, so self-hosted
deployments don't need new config to keep working.
When the lookup returns no candidates, one bounded retry is scheduled
~5s later to cover ClickHouse replication lag against `task_runs_v2`.
The Postgres status guard on both the candidate refetch and the inner
`updateMany` prevents double-promotion when a retry races with a
concurrent deploy.
Tests cover three existing PENDING_VERSION cases via a small
Postgres-backed test adapter; new ClickHouse-backed integration tests
will follow.
## Summary
Drops the unused composite Postgres index
`TaskRun_scheduleId_createdAt_idx`. The schedule list view reads from
ClickHouse, so this index served no Prisma query while still being
maintained on every `TaskRun` INSERT/UPDATE. Removing it reduces write
amplification on the primary database.
Sibling to the prior drop of `TaskRun_scheduleId_idx` and the earlier
removal of the `TaskRun.scheduleId` foreign key — all stemming from
migrating schedule-aware reads to ClickHouse.
## Verification
- Sampled `pg_stat_user_indexes` for `TaskRun` over multiple hours —
zero scans against this index.
- Grepped the codebase for any Prisma query filtering
`TaskRun.scheduleId` — none found. All schedule-aware listing routes
through `clickhouseRunsRepository`.
Make the Express server's `keepAliveTimeout` configurable via
`HTTP_KEEPALIVE_TIMEOUT_MS`. Default preserved at 65000 ms — no behavior
change if unset.
Workloads bundled with CLI versions before v4.4.4 use a strict zod enum
for `checkpoint.type` that only allows DOCKER and KUBERNETES. When a
customer's runs are routed via the compute path, those old runners
receive `type: "COMPUTE"` on `/snapshots/since/...` and `/dequeue`
responses and fail validation - blocking silent migration of existing
deployments.
The workload never reads the field - only validates the shape. Rewriting
COMPUTE -> KUBERNETES on the way out lets older runners keep parsing
while the database and internal services keep the real value. Limited to
the two workload-facing endpoints whose response includes a checkpoint;
`/continue`, `/attempts/start`, `/attempts/complete` all return shapes
without one.
Followup to #3114.
## Summary
Stamp every Sentry event with the signed-in user and the tenant (org /
project / env) the request belongs to, so "Users Impacted" counts
distinct humans and events become filterable per tenant.
**Design after review (current):**
- `user.id = real user cuid` (from `requireUser`). "Users Impacted"
counts humans, not tenants.
- Tenant context (org / project / env slugs, IDs, env type) moves
entirely onto tags: `org_slug`, `project_slug`, `env_slug`, `org_id`,
`project_id`, `project_ref`, `environment_id`, `env_type`, plus
`impersonating` when set.
- Backed by an `AsyncLocalStorage` scope established at the HTTP entry.
Each entry point fills what it knows; loaders enrich the same scope with
what they already have.
**Zero new database queries.** The middleware does a regex match only.
Dashboard loaders that already query Prisma gain a couple of extra
selected columns; nothing new round-trips.
## How it's wired
- **Express middleware (`tenantContextResolver.server.ts`)** — parses
the URL with a regex and always opens an ALS scope. Populates whatever
subset of slugs is present: `/orgs/:o` → just `orgSlug`;
`/orgs/:o/projects/:p` adds `projectSlug`; the full triple adds
`envSlug`. Non-tenant paths get an empty scope so loaders can still
enrich.
- **`_app/route.tsx`** — already calls `requireUser`. Adds
`tenantContext.enrich({ userId: user.id })` for every authenticated
dashboard request. No new query.
- **Env layout loader (`_app.orgs.$o.projects.$p.env.$e/route.tsx`)** —
its existing `prisma.project.findFirst` gains two columns in `select`
(`externalRef`, `organization.id`). After it picks an env, calls
`tenantContext.enrich({ orgId, projectId, projectRef, envId, envType
})`. Same query, +2 columns.
- **API path (`apiBuilder.server.ts`)** — wraps every handler in
`tenantContext.run(tenantContextFromAuthEnvironment(authenticationResult.environment),
…)`. The mapper pulls `userId` from `env.orgMember?.userId` (already
selected by `authIncludeBase` — no schema change). Covers
`createLoaderApiRoute`, `createActionApiRoute`, and
`createMultiMethodApiRoute`.
- **Event processor (`sentryTenantContext.server.ts`)** — registered in
`entry.server.tsx` so it lives in the Remix bundle and shares the same
`tenantContext` ALS instance as the middleware and loaders. Stamps
whatever's present; nothing forced.
## Example events from local verification
| URL | `user.id` | Tags |
|-----|-----------|------|
| `/orgs/:o/projects/:p/env/:e/...` | real user cuid | `org_slug`,
`project_slug`, `env_slug`, `org_id`, `project_id`, `project_ref`,
`environment_id`, `env_type` |
| `/orgs/:o/settings` (non-env-scoped) | real user cuid | `org_slug`
only |
| API request with `orgMember` | `orgMember.userId` | full tenant set |
| API request without `orgMember` | (unset) | full tenant set |
## Trade-offs
1. On env-scoped pages, errors that fire before the env layout loader's
enrich callback runs get slugs + `user.id` but not the tenant IDs /
`env_type`. Realistic errors deep in async work get the full set. (Same
race as before, narrower window now that slugs/`user.id` are populated
up-front by the middleware and `_app` enrich.)
2. API requests where the environment has no `orgMember` get tenant tags
but no `user.id`. Those events still show in the issue but don't
contribute to "Users Impacted".
## Out of scope (deferred)
Background workers (`redis-worker`, `schedule-engine`) and socket
handlers. Those entry points don't set `tenantContext.run` yet — their
events ship without tenant attribution until each is wired in a
follow-up.
## Tests
31 unit tests across 4 files. New tests notably cover:
- `parseTenantPath`: org-only, org+project, and full-triple URL
variants.
- `tenantContext.enrich`: in-place patch, no-op outside `run()`,
concurrent-scope isolation, empty-scope + enrich pattern (for non-tenant
pages).
- `tenantContextFromAuthEnvironment`: with and without `orgMember` —
verifies the API path's `user.id` mapping.
- `addTenantContextToEvent`: empty scope, userId-only, slugs-only, full
enrichment, conditional tag emission, preservation of prior `event.user`
fields.
## Test plan
- [ ] `pnpm run typecheck --filter webapp`
- [ ] `pnpm run test --filter webapp -- test/tenantContext.test.ts
test/sentryTenantContext.test.ts test/tenantContextResolver.test.ts
test/tenantContextFromAuthEnvironment.test.ts`
- [ ] Local manual: with `SENTRY_DSN` set, hit a dashboard URL and an
API route, confirm the captured events carry `user.id` + the expected
tag set in Sentry.
- [ ] After ship: confirm "Users Impacted" on a real Sentry issue
reflects distinct users (not tenants).

Added `OrganizationDataStore` which allows orgs to have data stored in
specific separate services.
For now this is just used for ClickHouse. When using ClickHouse we get a
client for the factory and pass in the org id.
Particular care has to be made with two hot-insert paths:
1. RunReplicationService
2. OTLPExporter

## Summary
`new TriggerClient({...})` exposes the management API (tasks, runs,
schedules, envvars, batch, queues, deployments, prompts, auth) as an
explicit instance with its own auth, preview branch, and baseURL.
Multiple clients can coexist in one process without mutating shared
global state — useful when a single service triggers across multiple
projects, environments, or preview branches.
```ts
import { TriggerClient } from "@trigger.dev/sdk";
const prod = new TriggerClient({ accessToken: process.env.TRIGGER_PROD_KEY });
const preview = new TriggerClient({
accessToken: process.env.TRIGGER_PREVIEW_KEY,
previewBranch: "signup-flow",
});
await prod.tasks.trigger("send-email", payload);
await preview.runs.list({ status: ["COMPLETED"] });
```
The existing global `configure()` API keeps working unchanged.
## Design
Instance methods enter an `AsyncLocalStorage`-backed scope (`sdkScope`)
before delegating to the existing module-level functions. The four
"pollution" points that previously read globals now consult the scope
first:
- `apiClientManager.{baseURL, accessToken, branchName}` and
`clientOrThrow` — identity fields are scope-only when scoped; `baseURL`
still falls back to `TRIGGER_API_URL` because plumbing (where the API
lives) is not identity.
- `taskContext.{ctx, worker, isWarmStart, isInsideTask}` — masked inside
an isolated scope so a `client.tasks.trigger(...)` from inside a task
doesn't leak the parent's `parentRunId` / `lockToVersion` / `isTest`
into a trigger that hits a different project.
- Inline `getEnvVar("TRIGGER_VERSION")` reads in `shared.ts` go through
a `scopedEnvVar` helper that returns `undefined` inside an isolated
scope.
The `TriggerClient` class itself is a thin wrapper that captures the
scope in its constructor and proxies each namespace method to enter that
scope before calling the existing impl. Generic inference (e.g.
`client.tasks.trigger<typeof t>(...)`) is preserved via `Pick<typeof ns,
keyof curatedSubset>` typings.
Two correctness fixes uncovered along the way are folded in:
- `apiClientManager.setGlobalAPIClientConfiguration` no longer silently
no-ops on the second call. `configure()` now actually overrides as users
expect (this is the root cause behind some "I changed the config but
nothing happened" reports).
- `apiClientManager.runWithConfig` (and therefore `auth.withAuth`) is
now backed by `sdkScope.withScope` instead of "mutate the global and
restore in finally". Two parallel `withAuth` calls with different
configs no longer stomp each other.
Surface curation: instance namespaces drop methods that don't make sense
per-instance — `batch.*AndWait` (runtime-dependent), `schedules.task` /
`schedules.timezones` (definition-time / stateless), `prompts.define`
(definition-time), `auth.configure` / `auth.withAuth` (global-only).
## Test plan
- [x] 9 runtime unit tests in `triggerClient.test.ts` cover: required
accessToken, instance auth + branch headers, no env fallback for
identity fields, no leakage between global and instance, four parallel
calls across two clients stay isolated, taskContext masking +
`inheritContext: true` override, `configure()` second-call override,
parallel `auth.withAuth` isolation.
- [x] 10 type-level assertions in `triggerClient.types.test.ts` using
`expectTypeOf` + `@ts-expect-error` lock in generic inference, return
type passthrough, overload preservation, and curated-surface drift.
- [x] Full SDK suite (219 tests) and core suite (530 tests) pass.
- [x] Webapp typecheck clean.
- [x] End-to-end smoke test against local webapp and a
freshly-provisioned cloud project — six concurrent multi-client triggers
all returned 200 with run IDs, headers per-client as expected.
- [ ] Reviewer: run `references/multi-client` per its `README.md` to
reproduce the smoke test locally.
## Try it
`references/multi-client` is a new reference workspace that exercises
this end-to-end:
- `src/trigger/echo.ts` — trivial target task
- `src/trigger/fanOut.ts` — opens two `TriggerClient`s from inside a
task, fires `echo` through each in parallel
- `src/external/main.ts` — external Node script with two clients
triggering `echo` sequentially and concurrently; logs every outgoing
request's `authorization` + `x-trigger-branch`
- `src/external/isolation.ts` — interleaves global `configure()` and an
instance call, asserts the captured fetch sequence shows no leakage
either way
Sibling to the weekly summary, focused on critical alerts only. Pings
Slack daily while any critical alerts are open; skips the post entirely
when zero, so no daily "all clear" noise.
- Daily 08:00 UTC cron + `workflow_dispatch` with `severity` input
(default `critical`, override to `high`/`medium`/`low` for manual
checks)
- Reuses the existing `dependabot-summary` environment (token, channel,
bot)
- Alerts link at the end is severity-filtered
## Summary
Two docs edits that close a footgun customers persisting transport state
can hit. Clearing `lastEventId` on `chat.endRun()` looks intuitive — the
Run ended, the cursor must be stale — but the cursor is sessionId-keyed,
not runId-keyed. Clearing it forces the next `sendMessages` to subscribe
from `seq_num=0`, which may hit the prior turn's still-durable
`turn-complete` record and close the SSE empty before the new Run's
chunks arrive.
Spells out the invariant in the frontend transport persistence table and
adds a Warning in the `chat.endRun()` reference.
## Test plan
- [x] Mintlify preview renders
- [x] No callout stacking
## Summary
Three post-merge fixes for the AI Agents docs (#3226), all caught by
review after merge.
## Fixes
- **`onTurnComplete` examples now use `db.$transaction`** — both the
Database persistence "Complete example" and the Lifecycle hooks
reference example were doing two separate `await` calls
(`db.chat.update` then `db.chatSession.upsert`). That's the exact
non-atomic pattern the warning earlier on the persistence page calls out
as ❌: a refresh between the two writes reads a stale `lastEventId` and
duplicates the assistant message on resume. Both examples now use the
recommended atomic form.
- **Background injection self-review prose aligned with the code** — the
prose said "gpt-4o-mini" but the example above it had been swapped to
`claude-haiku-4-5`. The Anthropic-sweep script only touched code blocks;
this prose line wasn't picked up.
## Test plan
- [x] Both updated examples use `db.$transaction([...])`
- [x] Prose matches the model used in the code block
- [ ] Mintlify deployment passes

## Summary
2 bug fixes.
## Bug fixes
- Fix `chat.agent` skills silently missing in `trigger dev` for projects
whose task files read `process.env` at module top level (e.g. a
third-party SDK client initialized at import). Skill folders now bundle
into `.trigger/skills/` reliably regardless of which env vars are set
when the CLI launches.
([#3690](https://github.com/triggerdotdev/trigger.dev/pull/3690))

## Summary
`trigger.dev dev` was silently dropping registered `chat.agent` skills
for any project whose task files read `process.env` at module top level
— e.g. a third-party SDK client initialized at import. The agent would
boot fine, but `skill.local()` failed at runtime with `ENOENT` because
the skill folder was never copied into `.trigger/skills/`.
## Design
The CLI ran two indexer passes in dev: the worker's own indexer (with
the full env it eventually executes tasks in), and a separate
skill-discovery indexer with only the CLI process's env. Top-level reads
of vars like `TRIGGER_API_URL` imported cleanly in the worker pass and
threw in the skill pass — the latter caught the error, warned, and
skipped skill copying. Failure was silent enough that `skill.local()`
only surfaced it at task runtime.
The skill registry is already part of the worker manifest. This PR drops
the duplicate pass and copies skill folders from that manifest after the
worker initializes. One indexer instead of two; a bad `SKILL.md` now
surfaces as a startup error instead of silently disappearing skills.
Deploy is unaffected — its skill discovery uses the project's
environment variables (fetched via the API, which fills in
`TRIGGER_API_URL` etc.), so the dev failure mode doesn't reach there.
## Test plan
- [x] New `references/agent-skills` reference project with
`skills.define` + a task that calls `skill.local()` and runs a bundled
script
- [x] On `main`, adding a top-level
`process.env.TRIGGER_API_URL!.includes(...)` read in any task file
reproduces the symptom: warning at dev startup, no `.trigger/skills/`
folder, `skill.local()` fails with ENOENT
- [x] On this branch, same project boots clean and `skill.local()` works
end-to-end
- [x] Deploy still works end-to-end with the new reference project
On a warm worker process, a task whose `task()` definition is loaded via
`await import(...)` from inside another task's `run()` could end up
permanently missing from the catalog: the `task()` call fired with no
`_currentFileContext` set, `registerTaskMetadata` silently returned, and
Node's ESM module cache then blocked the worker's setContext + re-import
recovery from ever firing the call again. Subsequent runs of that task
on the same warm process failed with `COULD_NOT_FIND_EXECUTOR` until the
process hit `maxExecutionsPerProcess` and exited.
All five of these had to coincide on the same worker for the bug to
surface:
1. `processKeepAlive` enabled (so catalog state survives across runs).
2. A `run()` function (or lifecycle hook) does `await import(...)`.
3. The import's transitive static graph reaches a `task()` /
`schemaTask()` call.
4. The task containing the dynamic import is the **first** task to run
on a given warm worker process — so the dropped `task()` calls fire on
this process for the first time, are silently dropped, and Node's module
cache locks the wrong outcome in.
5. A subsequent run for one of the dropped task ids lands on the same
warm worker before it recycles.
The runtime workers now set a sentinel file context (`<no-context>`)
around the `executor.execute(...)` call, so `task()` invocations firing
during a run register normally. The catalog detects the sentinel and
emits a one-time `console.warn` per task id so the pattern stays visible
without spamming. The indexer never sets this context, so deploy-time
behavior is unchanged.
Repro is `references/hello-world/src/trigger/dynamicImportRepro*.ts`.
Verified end-to-end against a deployed image with firestarter
warm-starts on: pre-fix saw `COULD_NOT_FIND_EXECUTOR` on children that
landed on the parent-poisoned worker; post-fix all 23/23 runs succeeded
and the warning surfaces in the parent's run trace.
## Summary
44 improvements, 1 bug fix.
## Improvements
- **AI Prompts** — define prompt templates as code alongside your tasks,
version them on deploy, and override the text or model from the
dashboard without redeploying. Prompts integrate with the Vercel AI SDK
via `toAISDKTelemetry()` (links every generation span back to the
prompt) and with `chat.agent` via `chat.prompt.set()` +
`chat.toStreamTextOptions()`.
([#3629](https://github.com/triggerdotdev/trigger.dev/pull/3629))
- **Code-defined, deploy-versioned templates** — define with
`prompts.define({ id, model, config, variables, content })`. Every
deploy creates a new version visible in the dashboard. Mustache-style
placeholders (`{{var}}`, `{{#cond}}...{{/cond}}`) with Zod / ArkType /
Valibot-typed variables.
- **Dashboard overrides** — change a prompt's text or model from the
dashboard without redeploying. Overrides take priority over the deployed
"current" version and are environment-scoped (dev / staging / production
independent).
- **Resolve API** — `prompt.resolve(vars, { version?, label? })` returns
the compiled `text`, resolved `model`, `version`, and labels. Standalone
`prompts.resolve<typeof handle>(slug, vars)` for cross-file resolution
with full type inference on slug and variable shape.
- **AI SDK integration** — spread `resolved.toAISDKTelemetry({ ...extra
})` into any `generateText` / `streamText` call and every generation
span links to the prompt in the dashboard alongside its input variables,
model, tokens, and cost.
- **`chat.agent` integration** — `chat.prompt.set(resolved)` stores the
resolved prompt run-scoped; `chat.toStreamTextOptions({ registry })`
pulls `system`, `model` (resolved via the AI SDK provider registry),
`temperature` / `maxTokens` / etc., and telemetry into a single spread
for `streamText`.
- **Management SDK** — `prompts.list()`, `prompts.versions(slug)`,
`prompts.promote(slug, version)`, `prompts.createOverride(slug, body)`,
`prompts.updateOverride(slug, body)`, `prompts.removeOverride(slug)`,
`prompts.reactivateOverride(slug, version)`.
- **Dashboard** — prompts list with per-prompt usage sparklines;
per-prompt detail with Template / Details / Versions / Generations /
Metrics tabs. AI generation spans get a custom inspector showing the
linked prompt's metadata, input variables, and template content
alongside model, tokens, cost, and the message thread.
- Adds `onBoot` to `chat.agent` — a lifecycle hook that fires once per
worker process picking up the chat. Runs for the initial run, preloaded
runs, AND reactive continuation runs (post-cancel, crash, `endRun`,
`requestUpgrade`, OOM retry), before any other hook. Use it to
initialize `chat.local`, open per-process resources, or re-hydrate state
from your DB on continuation — anywhere the SAME run picking up after
suspend/resume isn't enough.
([#3543](https://github.com/triggerdotdev/trigger.dev/pull/3543))
- **AI SDK `useChat` integration** — a custom
[`ChatTransport`](https://sdk.vercel.ai/docs/ai-sdk-ui/transport)
(`useTriggerChatTransport`) plugs straight into Vercel AI SDK's
`useChat` hook. Text streaming, tool calls, reasoning, and `data-*`
parts all work natively over Trigger.dev's realtime streams. No custom
API routes needed.
- **First-turn fast path (`chat.headStart`)** — opt-in handler that runs
the first turn's `streamText` step in your warm server process while the
agent run boots in parallel, cutting cold-start TTFC by roughly half
(measured 2801ms → 1218ms on `claude-sonnet-4-6`). The agent owns step
2+ (tool execution, persistence, hooks) so heavy deps stay where they
belong. Web Fetch handler works natively in Next.js, Hono, SvelteKit,
Remix, Workers, etc.; bridge to Express/Fastify/Koa via
`chat.toNodeListener`. New `@trigger.dev/sdk/chat-server` subpath.
- **Multi-turn durability via Sessions** — every chat is backed by a
durable Session that outlives any individual run. Conversations resume
across page refreshes, idle timeout, crashes, and deploys; `resume:
true` reconnects via `lastEventId` so clients only see new chunks.
`sessions.list` enumerates chats for inbox-style UIs.
- **Auto-accumulated history, delta-only wire** — the backend
accumulates the full conversation across turns; clients only ship the
new message each turn. Long chats never hit the 512 KiB body cap.
Register `hydrateMessages` to be the source of truth yourself.
- **Lifecycle hooks** — `onPreload`, `onChatStart`,
`onValidateMessages`, `hydrateMessages`, `onTurnStart`,
`onBeforeTurnComplete`, `onTurnComplete`, `onChatSuspend`,
`onChatResume` — for persistence, validation, and post-turn work.
- **Stop generation** — client-driven `transport.stopGeneration(chatId)`
aborts mid-stream; the run stays alive for the next message, partial
response is captured, and aborted parts (stuck `partial-call` tools,
in-progress reasoning) are auto-cleaned.
- **Tool approvals (HITL)** — tools with `needsApproval: true` pause
until the user approves or denies via `addToolApprovalResponse`. The
runtime reconciles the updated assistant message by ID and continues
`streamText`.
- **Steering and background injection** — `pendingMessages` injects user
messages between tool-call steps so users can steer the agent
mid-execution; `chat.inject()` + `chat.defer()` adds context from
background work (self-review, RAG, safety checks) between turns.
- **Actions** — non-turn frontend commands (undo, rollback, regenerate,
edit) sent via `transport.sendAction`. Fire `hydrateMessages` +
`onAction` only — no turn hooks, no `run()`. `onAction` can return a
`StreamTextResult` for a model response, or `void` for side-effect-only.
- **Typed state primitives** — `chat.local<T>` for per-run state
accessible from hooks, `run()`, tools, and subtasks (auto-serialized
through `ai.toolExecute`); `chat.store` for typed shared data between
agent and client; `chat.history` for reading and mutating the message
chain; `clientDataSchema` for typed `clientData` in every hook.
- **`chat.toStreamTextOptions()`** — one spread into `streamText` wires
up versioned system [Prompts](https://trigger.dev/docs/ai/prompts),
model resolution, telemetry metadata, compaction, steering, and
background injection.
- **Multi-tab coordination** — `multiTab: true` + `useMultiTabChat`
prevents duplicate sends and syncs state across browser tabs via
`BroadcastChannel`. Non-active tabs go read-only with live updates.
- **Network resilience** — built-in indefinite retry with bounded
backoff, reconnect on `online` / tab refocus / bfcache restore,
`Last-Event-ID` mid-stream resume. No app code needed.
- **Sessions** — a durable, run-aware stream channel keyed on a stable
`externalId`. A Session is the unit of state that owns a multi-run
conversation: messages flow through `.in`, responses through `.out`,
both survive run boundaries. Sessions back the new `chat.agent` runtime,
and you can build on them directly for any pattern that needs durable
bi-directional streaming across runs.
([#3542](https://github.com/triggerdotdev/trigger.dev/pull/3542))
- Add `ai.toolExecute(task)` so you can wire a Trigger subtask in as the
`execute` handler of an AI SDK `tool()` while defining `description` and
`inputSchema` yourself — useful when you want full control over the tool
surface and just need Trigger's subtask machinery for the body.
([#3546](https://github.com/triggerdotdev/trigger.dev/pull/3546))
- Type `chat.createStartSessionAction` against your chat agent so
`clientData` is typed end-to-end on the first turn:
([#3684](https://github.com/triggerdotdev/trigger.dev/pull/3684))
- Add `region` to the runs list / retrieve API: filter runs by region
(`runs.list({ region: "..." })` / `filter[region]=<masterQueue>`) and
read each run's executing region from the new `region` field on the
response.
([#3612](https://github.com/triggerdotdev/trigger.dev/pull/3612))
- Add `TRIGGER_BUILD_SKIP_REWRITE_TIMESTAMP=1` escape hatch for local
self-hosted builds whose buildx driver doesn't support
`rewrite-timestamp` alongside push (e.g. orbstack's default `docker`
driver).
([#3618](https://github.com/triggerdotdev/trigger.dev/pull/3618))
- Reject overlong `idempotencyKey` values at the API boundary so they no
longer trip an internal size limit on the underlying unique index and
surface as a generic 500. Inputs are capped at 2048 characters — well
above what `idempotencyKeys.create()` produces (a 64-character hash) and
above any realistic raw key. Applies to `tasks.trigger`,
`tasks.batchTrigger`, `batch.create` (Phase 1 streaming batches),
`wait.createToken`, `wait.forDuration`, and the input/session stream
waitpoint endpoints. Over-limit requests now return a structured 400
instead.
([#3560](https://github.com/triggerdotdev/trigger.dev/pull/3560))
- **AI SDK `useChat` integration** — a custom
[`ChatTransport`](https://sdk.vercel.ai/docs/ai-sdk-ui/transport)

- **Network resilience** — built-in indefinite retry with bounded
backoff, reconnect on `online` / tab refocus / bfcache restore,
`Last-Event-ID` mid-stream resume. No app code needed.
- Retry `TASK_PROCESS_SIGSEGV` task crashes under the user's retry
policy instead of failing the run on the first segfault. SIGSEGV in Node
tasks is frequently non-deterministic (native addon races, JIT/GC
interaction, near-OOM in native code, host issues), so retrying on a
fresh process often succeeds. The retry is gated by the task's existing
`retry` config + `maxAttempts` — same path `TASK_PROCESS_SIGTERM` and
uncaught exceptions already use — so tasks without a retry policy still
fail fast.
([#3552](https://github.com/triggerdotdev/trigger.dev/pull/3552))
- The public interfaces for a plugin system. Initially consolidated
authentication and authorization interfaces.
([#3499](https://github.com/triggerdotdev/trigger.dev/pull/3499))
- Add MollifierBuffer and MollifierDrainer primitives for trigger burst
smoothing.
([#3614](https://github.com/triggerdotdev/trigger.dev/pull/3614))
## Bug fixes
- Fix `LocalsKey<T>` type incompatibility across dual-package builds.
The phantom value-type brand no longer uses a module-level `unique
symbol`, so a single TypeScript compilation that resolves the type from
both the ESM and CJS outputs (which can happen under certain pnpm
hoisting layouts) no longer sees two structurally-incompatible variants
of the same type.

### Minor Changes
- **AI Prompts** — define prompt templates as code alongside your tasks,
version them on deploy, and override the text or model from the
dashboard without redeploying. Prompts integrate with the Vercel AI SDK
via `toAISDKTelemetry()` (links every generation span back to the
prompt) and with `chat.agent` via `chat.prompt.set()` +
`chat.toStreamTextOptions()`.
([#3629](https://github.com/triggerdotdev/trigger.dev/pull/3629))
```ts
import { prompts } from "@trigger.dev/sdk";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";
import { z } from "zod";
export const supportPrompt = prompts.define({
id: "customer-support",
model: "gpt-4o",
config: { temperature: 0.7 },
variables: z.object({
customerName: z.string(),
plan: z.string(),
issue: z.string(),
}),
content: `You are a support agent for Acme.
Customer: {{customerName}} ({{plan}} plan)
Issue: {{issue}}`,
});
const resolved = await supportPrompt.resolve({
customerName: "Alice",
plan: "Pro",
issue: "Can't access billing",
});
const result = await generateText({
model: openai(resolved.model ?? "gpt-4o"),
system: resolved.text,
prompt: "Can't access billing",
...resolved.toAISDKTelemetry(),
});
```
**What you get:**
- **Code-defined, deploy-versioned templates** — define with
`prompts.define({ id, model, config, variables, content })`. Every
deploy creates a new version visible in the dashboard. Mustache-style
placeholders (`{{var}}`, `{{#cond}}...{{/cond}}`) with Zod / ArkType /
Valibot-typed variables.
- **Dashboard overrides** — change a prompt's text or model from the
dashboard without redeploying. Overrides take priority over the deployed
"current" version and are environment-scoped (dev / staging / production
independent).
- **Resolve API** — `prompt.resolve(vars, { version?, label? })` returns
the compiled `text`, resolved `model`, `version`, and labels. Standalone
`prompts.resolve<typeof handle>(slug, vars)` for cross-file resolution
with full type inference on slug and variable shape.
- **AI SDK integration** — spread `resolved.toAISDKTelemetry({ ...extra
})` into any `generateText` / `streamText` call and every generation
span links to the prompt in the dashboard alongside its input variables,
model, tokens, and cost.
- **`chat.agent` integration** — `chat.prompt.set(resolved)` stores the
resolved prompt run-scoped; `chat.toStreamTextOptions({ registry })`
pulls `system`, `model` (resolved via the AI SDK provider registry),
`temperature` / `maxTokens` / etc., and telemetry into a single spread
for `streamText`.
- **Management SDK** — `prompts.list()`, `prompts.versions(slug)`,
`prompts.promote(slug, version)`, `prompts.createOverride(slug, body)`,
`prompts.updateOverride(slug, body)`, `prompts.removeOverride(slug)`,
`prompts.reactivateOverride(slug, version)`.
- **Dashboard** — prompts list with per-prompt usage sparklines;
per-prompt detail with Template / Details / Versions / Generations /
Metrics tabs. AI generation spans get a custom inspector showing the
linked prompt's metadata, input variables, and template content
alongside model, tokens, cost, and the message thread.
See [/docs/ai/prompts](https://trigger.dev/docs/ai/prompts) for the full
reference — template syntax, version resolution order, override
workflow, and type utilities (`PromptHandle`, `PromptIdentifier`,
`PromptVariables`).
- Adds `onBoot` to `chat.agent` — a lifecycle hook that fires once per
worker process picking up the chat. Runs for the initial run, preloaded
runs, AND reactive continuation runs (post-cancel, crash, `endRun`,
`requestUpgrade`, OOM retry), before any other hook. Use it to
initialize `chat.local`, open per-process resources, or re-hydrate state
from your DB on continuation — anywhere the SAME run picking up after
suspend/resume isn't enough.
([#3543](https://github.com/triggerdotdev/trigger.dev/pull/3543))
```ts
const userContext = chat.local<{ name: string; plan: string }>({ id:
"userContext" });
export const myChat = chat.agent({
id: "my-chat",
onBoot: async ({ clientData, continuation }) => {
const user = await db.user.findUnique({ where: { id: clientData.userId }
});
userContext.init({ name: user.name, plan: user.plan });
},
run: async ({ messages, signal }) =>
streamText({ model: openai("gpt-4o"), messages, abortSignal: signal }),
});
```
Use `onBoot` (not `onChatStart`) for state setup that must run every
time a worker picks up the chat — `onChatStart` fires once per chat and
won't run on continuation, leaving `chat.local` uninitialized when
`run()` tries to use it.
- **AI Agents** — run AI SDK chat completions as durable Trigger.dev
agents instead of fragile API routes. Define an agent in one function,
point `useChat` at it from React, and the conversation survives page
refreshes, network blips, and process restarts.
([#3543](https://github.com/triggerdotdev/trigger.dev/pull/3543))
```ts
import { chat } from "@trigger.dev/sdk/ai";
import { streamText } from "ai";
import { openai } from "@ai-sdk/openai";
export const myChat = chat.agent({
id: "my-chat",
run: async ({ messages, signal }) =>
streamText({ model: openai("gpt-4o"), messages, abortSignal: signal }),
});
```
```tsx
import { useChat } from "@ai-sdk/react";
import { useTriggerChatTransport } from "@trigger.dev/sdk/chat/react";
const transport = useTriggerChatTransport({ task: "my-chat",
accessToken, startSession });
const { messages, sendMessage } = useChat({ transport });
```
**What you get:**
- **AI SDK `useChat` integration** — a custom
[`ChatTransport`](https://sdk.vercel.ai/docs/ai-sdk-ui/transport)
(`useTriggerChatTransport`) plugs straight into Vercel AI SDK's
`useChat` hook. Text streaming, tool calls, reasoning, and `data-*`
parts all work natively over Trigger.dev's realtime streams. No custom
API routes needed.
- **First-turn fast path (`chat.headStart`)** — opt-in handler that runs
the first turn's `streamText` step in your warm server process while the
agent run boots in parallel, cutting cold-start TTFC by roughly half
(measured 2801ms → 1218ms on `claude-sonnet-4-6`). The agent owns step
2+ (tool execution, persistence, hooks) so heavy deps stay where they
belong. Web Fetch handler works natively in Next.js, Hono, SvelteKit,
Remix, Workers, etc.; bridge to Express/Fastify/Koa via
`chat.toNodeListener`. New `@trigger.dev/sdk/chat-server` subpath.
- **Multi-turn durability via Sessions** — every chat is backed by a
durable Session that outlives any individual run. Conversations resume
across page refreshes, idle timeout, crashes, and deploys; `resume:
true` reconnects via `lastEventId` so clients only see new chunks.
`sessions.list` enumerates chats for inbox-style UIs.
- **Auto-accumulated history, delta-only wire** — the backend
accumulates the full conversation across turns; clients only ship the
new message each turn. Long chats never hit the 512 KiB body cap.
Register `hydrateMessages` to be the source of truth yourself.
- **Lifecycle hooks** — `onPreload`, `onChatStart`,
`onValidateMessages`, `hydrateMessages`, `onTurnStart`,
`onBeforeTurnComplete`, `onTurnComplete`, `onChatSuspend`,
`onChatResume` — for persistence, validation, and post-turn work.
- **Stop generation** — client-driven `transport.stopGeneration(chatId)`
aborts mid-stream; the run stays alive for the next message, partial
response is captured, and aborted parts (stuck `partial-call` tools,
in-progress reasoning) are auto-cleaned.
- **Tool approvals (HITL)** — tools with `needsApproval: true` pause
until the user approves or denies via `addToolApprovalResponse`. The
runtime reconciles the updated assistant message by ID and continues
`streamText`.
- **Steering and background injection** — `pendingMessages` injects user
messages between tool-call steps so users can steer the agent
mid-execution; `chat.inject()` + `chat.defer()` adds context from
background work (self-review, RAG, safety checks) between turns.
- **Actions** — non-turn frontend commands (undo, rollback, regenerate,
edit) sent via `transport.sendAction`. Fire `hydrateMessages` +
`onAction` only — no turn hooks, no `run()`. `onAction` can return a
`StreamTextResult` for a model response, or `void` for side-effect-only.
- **Typed state primitives** — `chat.local<T>` for per-run state
accessible from hooks, `run()`, tools, and subtasks (auto-serialized
through `ai.toolExecute`); `chat.store` for typed shared data between
agent and client; `chat.history` for reading and mutating the message
chain; `clientDataSchema` for typed `clientData` in every hook.
- **`chat.toStreamTextOptions()`** — one spread into `streamText` wires
up versioned system [Prompts](https://trigger.dev/docs/ai/prompts),
model resolution, telemetry metadata, compaction, steering, and
background injection.
- **Multi-tab coordination** — `multiTab: true` + `useMultiTabChat`
prevents duplicate sends and syncs state across browser tabs via
`BroadcastChannel`. Non-active tabs go read-only with live updates.
- **Network resilience** — built-in indefinite retry with bounded
backoff, reconnect on `online` / tab refocus / bfcache restore,
`Last-Event-ID` mid-stream resume. No app code needed.
See [/docs/ai-chat](https://trigger.dev/docs/ai-chat/overview) for the
full surface — quick start, three backend approaches (`chat.agent`,
`chat.createSession`, raw task), persistence and code-sandbox patterns,
type-level guides, and API reference.
- Add read primitives to `chat.history` for HITL flows:
`getPendingToolCalls()`, `getResolvedToolCalls()`,
`extractNewToolResults(message)`, `getChain()`, and
`findMessage(messageId)`. These lift the accumulator-walking logic that
customers building human-in-the-loop tools were re-implementing into the
SDK. ([#3543](https://github.com/triggerdotdev/trigger.dev/pull/3543))
Use `getPendingToolCalls()` to gate fresh user turns while a tool call
is awaiting an answer. Use `extractNewToolResults(message)` to dedup
tool results when persisting to your own store — the helper returns only
the parts whose `toolCallId` is not already resolved on the chain.
```ts
const pending = chat.history.getPendingToolCalls();
if (pending.length > 0) {
// an addToolOutput is expected before a new user message
}
onTurnComplete: async ({ responseMessage }) => {
const newResults = chat.history.extractNewToolResults(responseMessage);
for (const r of newResults) {
await db.toolResults.upsert({ id: r.toolCallId, output: r.output,
errorText: r.errorText });
}
};
```
- **Sessions** — a durable, run-aware stream channel keyed on a stable
`externalId`. A Session is the unit of state that owns a multi-run
conversation: messages flow through `.in`, responses through `.out`,
both survive run boundaries. Sessions back the new `chat.agent` runtime,
and you can build on them directly for any pattern that needs durable
bi-directional streaming across runs.
([#3542](https://github.com/triggerdotdev/trigger.dev/pull/3542))
```ts
import { sessions, tasks } from "@trigger.dev/sdk";
// Trigger a task and subscribe to its session output in one call
const { runId, stream } = await tasks.triggerAndSubscribe("my-task",
payload, {
externalId: "user-456",
});
for await (const chunk of stream) {
// ...
}
// Enumerate existing sessions (powers inbox-style UIs without a
separate index)
for await (const s of sessions.list({ type: "chat.agent", tag:
"user:user-456" })) {
console.log(s.id, s.externalId, s.createdAt, s.closedAt);
}
```
See [/docs/ai-chat/overview](https://trigger.dev/docs/ai-chat/overview)
for the full surface — Sessions powers the durable, resumable chat
runtime described there.
### Patch Changes
- Add Agent Skills for `chat.agent`. Drop a folder with a `SKILL.md` and
any helper scripts/references next to your task code, register it with
`skills.define({ id, path })`, and the CLI bundles it into the deploy
image automatically — no `trigger.config.ts` changes. The agent gets a
one-line summary in its system prompt and discovers full instructions on
demand via `loadSkill`, with `bash` and `readFile` tools scoped
per-skill (path-traversal guards, output caps, abort-signal
propagation).
([#3543](https://github.com/triggerdotdev/trigger.dev/pull/3543))
```ts
const pdfSkill = skills.define({ id: "pdf-extract", path:
"./skills/pdf-extract" });
chat.skills.set([await pdfSkill.local()]);
```
Built on the [AI SDK cookbook
pattern](https://ai-sdk.dev/cookbook/guides/agent-skills) — portable
across providers. SDK + CLI only for now; dashboard-editable `SKILL.md`
text is on the roadmap.
- Add `ai.toolExecute(task)` so you can wire a Trigger subtask in as the
`execute` handler of an AI SDK `tool()` while defining `description` and
`inputSchema` yourself — useful when you want full control over the tool
surface and just need Trigger's subtask machinery for the body.
([#3546](https://github.com/triggerdotdev/trigger.dev/pull/3546))
```ts
const myTool = tool({
description: "...",
inputSchema: z.object({ ... }),
execute: ai.toolExecute(mySubtask),
});
```
`ai.tool(task)` (`toolFromTask`) keeps doing the all-in-one wrap and now
aligns its return type with AI SDK's `ToolSet`. Minimum `ai` peer raised
to `^6.0.116` to avoid cross-version `ToolSet` mismatches in monorepos.
- Stamp `gen_ai.conversation.id` (the chat id) on every span and metric
emitted from inside a `chat.task` or `chat.agent` run. Lets you filter
dashboard spans, runs, and metrics by the chat conversation that
produced them — independent of the run boundary, so multi-run chats
correlate cleanly. No code changes required on the user side.
([#3543](https://github.com/triggerdotdev/trigger.dev/pull/3543))
- Type `chat.createStartSessionAction` against your chat agent so
`clientData` is typed end-to-end on the first turn:
([#3684](https://github.com/triggerdotdev/trigger.dev/pull/3684))
```ts
import { chat } from "@trigger.dev/sdk/ai";
import type { myChat } from "@/trigger/chat";
export const startChatSession = chat.createStartSessionAction<typeof
myChat>("my-chat");
// In the browser, threaded from the transport's typed startSession
callback:
const transport = useTriggerChatTransport<typeof myChat>({
task: "my-chat",
startSession: ({ chatId, clientData }) => startChatSession({ chatId,
clientData }),
// ...
});
```
`ChatStartSessionParams` gains a typed `clientData` field — folded into
the first run's `payload.metadata` so `onPreload` / `onChatStart` see
the same shape per-turn `metadata` carries via the transport. The opaque
session-level `metadata` field is unchanged.
- Unit-test `chat.agent` definitions offline with `mockChatAgent` from
`@trigger.dev/sdk/ai/test`. Drives a real agent's turn loop in-process —
no network, no task runtime — so you can send messages, actions, and
stop signals via driver methods, inspect captured output chunks, and
verify hooks fire. Pairs with `MockLanguageModelV3` from `ai/test` for
model mocking. `setupLocals` lets you pre-seed `locals` (DB clients,
service stubs) before `run()` starts.
([#3543](https://github.com/triggerdotdev/trigger.dev/pull/3543))
The broader `runInMockTaskContext` harness it's built on lives at
`@trigger.dev/core/v3/test` — useful for unit-testing any task code, not
just chat.
- Add `region` to the runs list / retrieve API: filter runs by region
(`runs.list({ region: "..." })` / `filter[region]=<masterQueue>`) and
read each run's executing region from the new `region` field on the
response.
([#3612](https://github.com/triggerdotdev/trigger.dev/pull/3612))
- Updated dependencies:
- `@trigger.dev/core@4.5.0-rc.0`

- Add `TRIGGER_BUILD_SKIP_REWRITE_TIMESTAMP=1` escape hatch for local
self-hosted builds whose buildx driver doesn't support
`rewrite-timestamp` alongside push (e.g. orbstack's default `docker`
driver).
([#3618](https://github.com/triggerdotdev/trigger.dev/pull/3618))
- The CLI MCP server's agent-chat tools (`start_agent_chat`,
`send_agent_message`, `close_agent_chat`) now run on the new Sessions
primitive, so AI assistants driving a `chat.agent` get the same
idempotent-by-`chatId`, durable-across-runs behavior the browser
transport gets. Required PAT scopes go from `write:inputStreams` to
`read:sessions` + `write:sessions`.
([#3546](https://github.com/triggerdotdev/trigger.dev/pull/3546))
- MCP `list_runs` tool: add a `region` filter input and surface each
run's executing region in the formatted summary.
([#3612](https://github.com/triggerdotdev/trigger.dev/pull/3612))
- Updated dependencies:

- Reject overlong `idempotencyKey` values at the API boundary so they no
longer trip an internal size limit on the underlying unique index and
surface as a generic 500. Inputs are capped at 2048 characters — well
above what `idempotencyKeys.create()` produces (a 64-character hash) and
above any realistic raw key. Applies to `tasks.trigger`,
`tasks.batchTrigger`, `batch.create` (Phase 1 streaming batches),
`wait.createToken`, `wait.forDuration`, and the input/session stream
waitpoint endpoints. Over-limit requests now return a structured 400
instead.
([#3560](https://github.com/triggerdotdev/trigger.dev/pull/3560))
- **AI Agents** — run AI SDK chat completions as durable Trigger.dev
agents instead of fragile API routes. Define an agent in one function,
point `useChat` at it from React, and the conversation survives page
refreshes, network blips, and process restarts.
([#3543](https://github.com/triggerdotdev/trigger.dev/pull/3543))
```ts
import { chat } from "@trigger.dev/sdk/ai";
import { streamText } from "ai";
import { openai } from "@ai-sdk/openai";
export const myChat = chat.agent({
id: "my-chat",
run: async ({ messages, signal }) =>
streamText({ model: openai("gpt-4o"), messages, abortSignal: signal }),
});
```
```tsx
import { useChat } from "@ai-sdk/react";
import { useTriggerChatTransport } from "@trigger.dev/sdk/chat/react";
const transport = useTriggerChatTransport({ task: "my-chat",
accessToken, startSession });
const { messages, sendMessage } = useChat({ transport });
```
**What you get:**
- **AI SDK `useChat` integration** — a custom
[`ChatTransport`](https://sdk.vercel.ai/docs/ai-sdk-ui/transport)
(`useTriggerChatTransport`) plugs straight into Vercel AI SDK's
`useChat` hook. Text streaming, tool calls, reasoning, and `data-*`
parts all work natively over Trigger.dev's realtime streams. No custom
API routes needed.
- **First-turn fast path (`chat.headStart`)** — opt-in handler that runs
the first turn's `streamText` step in your warm server process while the
agent run boots in parallel, cutting cold-start TTFC by roughly half
(measured 2801ms → 1218ms on `claude-sonnet-4-6`). The agent owns step
2+ (tool execution, persistence, hooks) so heavy deps stay where they
belong. Web Fetch handler works natively in Next.js, Hono, SvelteKit,
Remix, Workers, etc.; bridge to Express/Fastify/Koa via
`chat.toNodeListener`. New `@trigger.dev/sdk/chat-server` subpath.
- **Multi-turn durability via Sessions** — every chat is backed by a
durable Session that outlives any individual run. Conversations resume
across page refreshes, idle timeout, crashes, and deploys; `resume:
true` reconnects via `lastEventId` so clients only see new chunks.
`sessions.list` enumerates chats for inbox-style UIs.
- **Auto-accumulated history, delta-only wire** — the backend
accumulates the full conversation across turns; clients only ship the
new message each turn. Long chats never hit the 512 KiB body cap.
Register `hydrateMessages` to be the source of truth yourself.
- **Lifecycle hooks** — `onPreload`, `onChatStart`,
`onValidateMessages`, `hydrateMessages`, `onTurnStart`,
`onBeforeTurnComplete`, `onTurnComplete`, `onChatSuspend`,
`onChatResume` — for persistence, validation, and post-turn work.
- **Stop generation** — client-driven `transport.stopGeneration(chatId)`
aborts mid-stream; the run stays alive for the next message, partial
response is captured, and aborted parts (stuck `partial-call` tools,
in-progress reasoning) are auto-cleaned.
- **Tool approvals (HITL)** — tools with `needsApproval: true` pause
until the user approves or denies via `addToolApprovalResponse`. The
runtime reconciles the updated assistant message by ID and continues
`streamText`.
- **Steering and background injection** — `pendingMessages` injects user
messages between tool-call steps so users can steer the agent
mid-execution; `chat.inject()` + `chat.defer()` adds context from
background work (self-review, RAG, safety checks) between turns.
- **Actions** — non-turn frontend commands (undo, rollback, regenerate,
edit) sent via `transport.sendAction`. Fire `hydrateMessages` +
`onAction` only — no turn hooks, no `run()`. `onAction` can return a
`StreamTextResult` for a model response, or `void` for side-effect-only.
- **Typed state primitives** — `chat.local<T>` for per-run state
accessible from hooks, `run()`, tools, and subtasks (auto-serialized
through `ai.toolExecute`); `chat.store` for typed shared data between
agent and client; `chat.history` for reading and mutating the message
chain; `clientDataSchema` for typed `clientData` in every hook.
- **`chat.toStreamTextOptions()`** — one spread into `streamText` wires
up versioned system [Prompts](https://trigger.dev/docs/ai/prompts),
model resolution, telemetry metadata, compaction, steering, and
background injection.
- **Multi-tab coordination** — `multiTab: true` + `useMultiTabChat`
prevents duplicate sends and syncs state across browser tabs via
`BroadcastChannel`. Non-active tabs go read-only with live updates.
- **Network resilience** — built-in indefinite retry with bounded
backoff, reconnect on `online` / tab refocus / bfcache restore,
`Last-Event-ID` mid-stream resume. No app code needed.
See [/docs/ai-chat](https://trigger.dev/docs/ai-chat/overview) for the
full surface — quick start, three backend approaches (`chat.agent`,
`chat.createSession`, raw task), persistence and code-sandbox patterns,
type-level guides, and API reference.
- Stamp `gen_ai.conversation.id` (the chat id) on every span and metric
emitted from inside a `chat.task` or `chat.agent` run. Lets you filter
dashboard spans, runs, and metrics by the chat conversation that
produced them — independent of the run boundary, so multi-run chats
correlate cleanly. No code changes required on the user side.
([#3543](https://github.com/triggerdotdev/trigger.dev/pull/3543))
- Fix `LocalsKey<T>` type incompatibility across dual-package builds.
The phantom value-type brand no longer uses a module-level `unique
symbol`, so a single TypeScript compilation that resolves the type from
both the ESM and CJS outputs (which can happen under certain pnpm
hoisting layouts) no longer sees two structurally-incompatible variants
of the same type.
([#3626](https://github.com/triggerdotdev/trigger.dev/pull/3626))
- Unit-test `chat.agent` definitions offline with `mockChatAgent` from
`@trigger.dev/sdk/ai/test`. Drives a real agent's turn loop in-process —
no network, no task runtime — so you can send messages, actions, and
stop signals via driver methods, inspect captured output chunks, and
verify hooks fire. Pairs with `MockLanguageModelV3` from `ai/test` for
model mocking. `setupLocals` lets you pre-seed `locals` (DB clients,
service stubs) before `run()` starts.
([#3543](https://github.com/triggerdotdev/trigger.dev/pull/3543))
The broader `runInMockTaskContext` harness it's built on lives at
`@trigger.dev/core/v3/test` — useful for unit-testing any task code, not
just chat.
- Retry `TASK_PROCESS_SIGSEGV` task crashes under the user's retry
policy instead of failing the run on the first segfault. SIGSEGV in Node
tasks is frequently non-deterministic (native addon races, JIT/GC
interaction, near-OOM in native code, host issues), so retrying on a
fresh process often succeeds. The retry is gated by the task's existing
`retry` config + `maxAttempts` — same path `TASK_PROCESS_SIGTERM` and
uncaught exceptions already use — so tasks without a retry policy still
fail fast.
([#3552](https://github.com/triggerdotdev/trigger.dev/pull/3552))
- Add `region` to the runs list / retrieve API: filter runs by region
(`runs.list({ region: "..." })` / `filter[region]=<masterQueue>`) and
read each run's executing region from the new `region` field on the
response.
([#3612](https://github.com/triggerdotdev/trigger.dev/pull/3612))
- **Sessions** — a durable, run-aware stream channel keyed on a stable
`externalId`. A Session is the unit of state that owns a multi-run
conversation: messages flow through `.in`, responses through `.out`,
both survive run boundaries. Sessions back the new `chat.agent` runtime,
and you can build on them directly for any pattern that needs durable
bi-directional streaming across runs.
([#3542](https://github.com/triggerdotdev/trigger.dev/pull/3542))

import { sessions, tasks } from "@trigger.dev/sdk";
// Trigger a task and subscribe to its session output in one call
const { runId, stream } = await tasks.triggerAndSubscribe("my-task",
payload, {
externalId: "user-456",
});
for await (const chunk of stream) {
// ...
}
// Enumerate existing sessions (powers inbox-style UIs without a
separate index)
for await (const s of sessions.list({ type: "chat.agent", tag:
"user:user-456" })) {
console.log(s.id, s.externalId, s.createdAt, s.closedAt);
}
```

## @trigger.dev/redis-worker@4.5.0-rc.0
### Patch Changes
- Add MollifierBuffer and MollifierDrainer primitives for trigger burst
smoothing.
([#3614](https://github.com/triggerdotdev/trigger.dev/pull/3614))
MollifierBuffer (`accept`, `pop`, `ack`, `requeue`, `fail`,
`evaluateTrip`) is a per-env FIFO over Redis with atomic Lua transitions
for status tracking. `evaluateTrip` is a sliding-window trip evaluator
the webapp gate uses to detect per-env trigger bursts.
MollifierDrainer pops entries through a polling loop with a
user-supplied handler. The loop survives transient Redis errors via
capped exponential backoff (up to 5s), and per-env pop failures don't
poison the rest of the batch — one env's blip is logged and counted as
failed for that tick. Rotation is two-level: orgs at the top, envs
within each org. The buffer maintains `mollifier:orgs` and
`mollifier:org-envs:${orgId}` atomically with per-env queues, so the
drainer walks orgs → envs directly without an in-memory cache. The
`maxOrgsPerTick` option (default 500) caps how many orgs are scheduled
per tick; for each picked org, one env is popped (rotating round-robin
within the org). An org with N envs gets the same per-tick scheduling
slot as an org with 1 env, so tenant-level drainage throughput is
determined by org count rather than env count.

## Summary
Two CI workflows were blocking the v4.5.0-rc.0 release PR (#3563) and
would block every future changeset release PR.
### 1. `changesets-pr.yml` — self-report `All PR Checks`
The changesets bot pushes commits authored by `GITHUB_TOKEN`. By GitHub
design, `GITHUB_TOKEN`-authored pushes can't trigger downstream
workflows (loop-prevention). That means `pr_checks.yml` never fires on
release-PR commits, leaving the required `All PR Checks` status
permanently `Expected — Waiting for status to be reported`. The PR can't
merge.
The fix: after `changesets/action` creates the PR, post a `success`
check with the exact `All PR Checks` context onto the PR's head SHA.
GitHub's required-check evaluation is satisfied by any check with the
right context name — the source doesn't have to be `pr_checks.yml`.
**Why this is safe:** the release PR only mechanically bumps
`package.json`, `pnpm-lock.yaml`, and `CHANGELOG.md` from changesets
that were already on `main` (and already ran full CI when they merged).
If a human ever pushes a commit to `changeset-release/main`,
`pr_checks.yml` fires on that push (real user, not `GITHUB_TOKEN`) and
posts its own `All PR Checks` status — last write wins for the same
context on the same SHA, so the human-push result overrides the
auto-success.
### 2. `vouch-check-pr.yml` — exempt `github-actions[bot]`
The `require-draft` job auto-closes any non-draft PR whose author is not
a `MEMBER`/`OWNER`/`COLLABORATOR`, with an explicit allowlist for
`devin-ai-integration[bot]` and `dependabot[bot]`. The changesets bot
publishes as `github-actions[bot]` with `author_association:
CONTRIBUTOR`, so every release PR was getting auto-closed on open with a
"please re-open as draft" comment. Add `github-actions[bot]` to the
exemption list.
## Test plan
- [ ] After merge, the next changeset bot push to
`changeset-release/main` should post `All PR Checks: success` on the
release PR's head SHA, and the PR should not get auto-closed by `Vouch -
Check PR`.
- [ ] Confirm `pr_checks.yml` still fires + gates normal
(human-authored) PRs to `main`.
## Summary
Pre-existing typecheck errors in `references/ai-chat` against the
current SDK shape. Unblocks `pnpm exec tsc --noEmit` in the reference
project.
## What changed
Three categories of fixes inside `references/ai-chat`. No SDK changes.
### 1. `payload.messages` → `payload.message`
The wire payload is now delta-only — one new message per trigger,
optional. Old code in two raw-task files reads `payload.messages`
(plural array) which no longer exists.
```ts
// before
const messages = await conversation.addIncoming(currentPayload.messages, ...);
// after
const messages = await conversation.addIncoming(
currentPayload.message ? [currentPayload.message] : [],
...
);
```
Same fix to the `chat.messages.on` handler, reading `msg.message`
(singular) instead of `msg.messages[length - 1]`.
### 2. `clientData` non-null assertion in `cf-trust-test`
`ChatTurnContext.clientData` is typed as `?: TClientData` on
`onTurnStart` / `run` event objects even when the agent declares a
`clientDataSchema`. The runtime validates against the schema before the
hook fires, so it's structurally non-null — but TypeScript can't know
that. Non-null assert for now.
Follow-up worth filing: narrow `ChatTurnContext.clientData` to
non-optional when the agent has a `clientDataSchema`. Same friction the
docs friction-test subagent flagged.
### 3. `stress-emit.parseConfig` retyped against `ModelMessage[]`
The `run` callback hands `messages: ModelMessage[]`, not `UIMessage[]`.
Update `parseConfig` to accept `ModelMessage[]` and pull text from
`content` (string or array-of-parts).
## Test plan
- [x] `pnpm exec tsc --noEmit` in `references/ai-chat` passes (was 8
errors, now 0)
## Summary
Type `chat.createStartSessionAction` against the chat agent so
`clientData` is typed end-to-end on the first turn. Closes the gap where
`useTriggerChatTransport`'s `startSession` callback already hands you a
typed `clientData` (via the transport generic) but the server-side
action couldn't accept it without untyped routing through the `metadata`
field.
## Design
`ChatStartSessionParams` gains a typed `clientData` field via the new
generic:
```ts
export type ChatStartSessionParams<TChat extends AnyTask = AnyTask> = {
chatId: string;
clientData?: InferChatClientData<TChat>;
triggerConfig?: Partial<SessionTriggerConfig>;
metadata?: Record<string, unknown>;
};
function createChatStartSessionAction<TChat extends AnyTask = AnyTask>(
taskId: string,
options?: CreateChatStartSessionActionOptions
): (params: ChatStartSessionParams<TChat>) => Promise<ChatStartSessionResult>
```
When provided, `clientData` is folded into the first run's
`triggerConfig.basePayload.metadata`, so `onPreload` / `onChatStart` see
the same shape per-turn `metadata` carries via the transport. The opaque
session-level `metadata` field stays exactly as before — it lands on the
Session row, not the run payload.
## Usage
```ts
// actions.ts
import { chat } from "@trigger.dev/sdk/ai";
import type { myChat } from "@/trigger/chat";
export const startChatSession = chat.createStartSessionAction<typeof myChat>("my-chat");
```
```tsx
// Chat.tsx
const transport = useTriggerChatTransport<typeof myChat>({
task: "my-chat",
accessToken: ({ chatId }) => mintChatAccessToken(chatId),
startSession: ({ chatId, clientData }) =>
startChatSession({ chatId, clientData }),
});
```
## Test plan
- [x] `pnpm run build --filter @trigger.dev/sdk` passes
- [ ] Verify a `chat.agent` with `clientDataSchema` reads the typed
clientData from `onPreload` payload metadata on the first turn
(`OBJECT_STORE_BASE_URL`) and a named protocol provider
(`OBJECT_STORE_DEFAULT_PROTOCOL=s3`), chat.agent session snapshot writes
landed in the named provider but reads fell through to the default — so
the recovery boot couldn't find the snapshot it had just written.
After a mid-stream cancel, the missing snapshot triggered a fallback
replay path that dropped the user's follow-up message, leaving the chat
stuck in `submitted` indefinitely.
Fix:
- New `/api/v1/sessions/:id/snapshot-url` route handles PUT + GET
symmetrically — both prefix unprefixed keys with
`OBJECT_STORE_DEFAULT_PROTOCOL` so they always round-trip through the
same store.
- `Session.chatSnapshotStoragePath` persists the resolved URI on first
write so future protocol changes don't strand existing snapshots.
Reads prefer the stored URI and fall back to the computed default for
pre-column sessions.
- SDK calls `createChatSnapshotUploadUrl` / `getChatSnapshotUrl`; the
generic v1/v2 packets endpoints are unchanged.
## Test plan
- [x] Configure local with two providers (R2 default + MinIO `s3` named)
and `OBJECT_STORE_DEFAULT_PROTOCOL=s3`.
- [x] Reproduce hang: send a message, cancel mid-stream, send another —
without the fix it hangs in `submitted`; with the fix it streams.
- [x] Snapshot lands in the `s3`-protocol bucket and
`Session.chatSnapshotStoragePath` is set after first write.
- [x] SDK unit tests pass; webapp typecheck passes.
Env-var lookups via `GET
/api/v1/projects/:projectRef/envvars/:slug/:name` run a Prisma
`findMany` on `EnvironmentVariableValue` filtered by `environmentId` +
`isSecret`. The only existing indexes are the primary key and a unique
on `(variableId, environmentId)`, so `environmentId` is never the
leading column — the planner falls back to a Parallel Seq Scan over the
whole table to find what is, in practice, a handful of rows per
environment.
Two changes:
- Add a btree index on `EnvironmentVariableValue(environmentId)` so the
planner switches to an index scan. The composite `(variableId,
environmentId)` unique stays in place; the new index is purely additive.
- Route the `findMany` inside `getEnvironmentWithRedactedSecrets`
through the read replica via a new `replicaClient` constructor param on
the repository (defaulting to `$replica`, mirroring how `prismaClient`
defaults to `prisma`). Writes and read-after-write methods stay on the
primary.
## Test plan
- [ ] `pnpm run typecheck --filter webapp`
- [ ] Confirm `EXPLAIN` plan flips from Parallel Seq Scan to an index
scan
- [ ] Existing env-var route tests still pass
## Summary
- Dashboard loaders for runs / sessions / batches / schedule-detail
threw bare `Error("X not found")` when a slug didn't resolve. Remix
surfaces this as a 500 and Sentry captures it via auto-instrumentation,
producing ongoing noise from real users following stale preview-branch
or deleted-resource links (the URLs in those Sentry events all carry
`?_data=routes/...`, i.e. client-side revalidation, not full-page
navigation).
- Added a `throwNotFound(statusText)` helper in
`app/utils/httpErrors.ts` that throws a Response with status 404,
matching the established pattern in sibling routes (agents, alerts,
bulk-actions, etc.).
- Migrated 5 loader sites to `throwNotFound` (4× "Environment not
found", 1× "Schedule not found").
- Migrated 1 loader site (`runs._index` project branch) to
`redirectWithErrorMessage("/", request, "Project not found")` to match
the pre-existing convention used by every other dashboard route's
project-not-found branch.
- Intentionally **not** touched: bare `throw new Error("X not found")`
inside `resources.*` action routes (sit inside try/catch blocks that
already redirect with a flash message), the invariant assertion in
`vercel.connect.tsx`, and the admin config check in
`admin.api.v1.runs-replication.backfill.ts`.
## Where the fix is visible
Normal browser navigation to these URLs doesn't reach the buggy loaders
— the parent env-layout
(`_app.orgs.$organizationSlug.projects.$projectParam.env.$envParam/route.tsx`)
already filters missing envs/projects and redirects/404s before the
child loader runs. The bug fires exclusively when Remix calls a single
child loader via `?_data=routes/...`, which happens during client-side
navigation or `useRevalidator`. That matches every Sentry event URL.
## Test plan
- [x] Unit test for the new helper —
`apps/webapp/test/httpErrors.test.ts`
- [x] `pnpm run typecheck --filter webapp` clean
- [x] Manual verification via Playwright on `main` vs this branch (6
cases): main returns 500 for each defective `_data` URL; branch returns
404 or 204 + `X-Remix-Redirect` as designed
- [x] Verified user-visible 404 catch boundary on `schedules/<missing>`
(the one case reachable via normal nav)

## Summary
Five hardening fixes across `@trigger.dev/sdk`, `@trigger.dev/core`, and
`@trigger.dev/build`.
- `tasks.triggerAndSubscribe` now forwards caller `requestOptions`
(custom API keys, per-request overrides) to the underlying
`apiClient.triggerTask` call instead of silently dropping them.
- `SSEStreamSubscription` no longer retries permanent client errors
forever. The default `nonRetryableStatuses` widens from `[404, 410]` to
`[400, 404, 409, 410, 422]`, so a malformed session-stream request fails
fast instead of busy-looping under bounded backoff.
- Session writer falls back to manually wiring the caller's
`AbortSignal` on Node 18, where `AbortSignal.any` is unavailable.
Caller-driven cancellation now propagates on every supported runtime.
- `TriggerChatTransport` throws immediately when a `chat.handover`
response is missing `X-Trigger-Chat-Access-Token`, instead of silently
downgrading every subsequent turn back to the handover path. `dispose()`
aborts every active `session.out` subscription before tearing the
coordinator down, so unmount/navigation no longer leaves SSE readers in
flight.
- Removed the experimental `@trigger.dev/build/extensions/secureExec`
build extension. It will return alongside the sandbox feature it was
built to support.
## Test plan
- [ ] `pnpm run build --filter @trigger.dev/sdk --filter
@trigger.dev/core --filter @trigger.dev/build`
- [ ] `pnpm --filter @trigger.dev/sdk test --run` (183 tests, including
chat / chat-server / sessions / handover)
- [ ] `pnpm --filter @trigger.dev/core test --run`
- [ ] Manually trigger a `chat.handover` whose response strips
`X-Trigger-Chat-Access-Token`, and confirm the transport throws
synchronously rather than degrading.
- [ ] Unmount a chat UI mid-stream and confirm the active `session.out`
SSE connection closes immediately.
## Summary
The S2 access-token cache key was `${basin}:${streamPrefix}` — purely
server-derived but blind to the **scope/ops list** hardcoded one method
away. When the ops list changes in code (e.g. #3644 added `trim` so
`chat.agent`'s per-turn trim chain can issue `AppendRecord.trim()`),
pre-deploy tokens still in cache get returned to SDK callers for up to
the token's TTL (24h default), surfacing as `Operation not permitted`
403s on any op outside the old scope.
## Fix
Lift the ops list to a module constant and fold its sorted-join
fingerprint into the cache key:
```ts
const S2_TOKEN_OPS = ["append", "create-stream", "trim"] as const;
const S2_TOKEN_OPS_FINGERPRINT = [...S2_TOKEN_OPS].sort().join(",");
// in getS2AccessToken
const cacheKey = `${this.basin}:${this.streamPrefix}:${S2_TOKEN_OPS_FINGERPRINT}`;
// in s2IssueAccessToken
scope: { /* ... */ ops: [...S2_TOKEN_OPS], /* ... */ }
```
The fingerprint is derived from the single source of truth, so any
future scope change auto-invalidates without anyone remembering to bump
a literal version. The Unkey L1 (in-memory LRU) and L2 (Redis) layers
share the same key derivation, so both reset together on the next deploy
with no manual cache busting.
## Test plan
- [ ] `pnpm run typecheck --filter webapp`
- [ ] Run a multi-turn `chat.agent` chat via `references/ai-chat` and
confirm no `chat.agent: trim failed; will retry next turn` warn span
fires across turn-completes.
## Summary
The prerelease (snapshot) path of the release workflow fails immediately
whenever `main` carries an active `.changeset/pre.json` (i.e. during an
in-progress RC cycle, like the current v4 RC):
```
🦋 error Snapshot release is not allowed in pre mode
🦋 To resolve this exit the pre mode by running `changeset pre exit`
```
This blocks `chat-prerelease` snapshots from main even though the
snapshots are unrelated to the RC cycle.
Adds a conditional `changeset pre exit` step right before `Snapshot
version` in the prerelease job. The job runs on a checkout with
`persist-credentials: false`, so the `pre.json` deletion stays on the
runner's working tree — main's persisted pre-mode state is untouched,
and v4 RC publishes keep working normally.
## Test plan
- [ ] Re-run the `🦋 Changesets Release` workflow with `type=prerelease`,
`ref=main`, `prerelease_tag=chat-prerelease` and confirm it gets past
the snapshot step and publishes.
- [ ] Confirm `.changeset/pre.json` on `main` is unchanged after the
run.
## Summary
Companion to #3536, which patched routes that already had a leaking
`catch (e) { return json({error: e.message}, 500) }`. That pattern can't
reach routes which have no catch in the first place — when those throw,
Remix's default error path serializes `error.message` into the response
body, and the SDK then wraps the leaked string as `TriggerApiError`.
Across 28 raw api.v1 loaders/actions plus one dashboard polling
endpoint, each handler now:
- Wraps its body in `try { ... } catch (error) { ... }`.
- Re-throws `Response` instances so auth helpers' `throw json(...)` /
`throw redirect(...)` pass through unchanged.
- Logs non-Response errors via `logger.error` so server-side visibility
is preserved.
- Returns a generic body — `{"error": "Internal Server Error"}` 500 for
raw API routes, or `{ changelogs: [] }` 200 for the polling widget
(degrade silently across transient blips; the consumer hook already
coped with empty payloads).
For six routes where #3536 left an inner try/catch covering only a
service call (`alertChannels`, `batches.results`,
`deployments.finalize`, `deployments.background-workers`,
`deployments.promote`, `projects.background-workers`): an outer
try/catch is added so auth/parsing failures are also sanitized. Inner
typed-error handling (`ServiceValidationError` → 422 with message, etc.)
is preserved exactly.
For two routes whose existing catch returned 400 + `error.message`
(`api.v1.authorization-code`, `api.v1.orgs.\$orgParam.projects` action):
the body is sanitized to a generic per-route string. **Status code stays
400** — clients that key on the 4xx/5xx distinction (and the SDK's
no-retry-on-4xx behavior) are unaffected.
## Test plan
- [x] \`pnpm run typecheck --filter webapp\`
- [x] Per-route synthetic-throw probe: inject \`throw new
Error("SYNTHETIC ...")\` at the top of each catch'd try, curl the route
with a dummy bearer, confirm the response body is the generic shape and
that the synthetic message lands server-side via \`logger.error\`. 29
routes verified.
- [x] Real-P1001 probe on the envvars loader: \`docker stop database\`
mid-flight, confirm response is generic 500 (not the leaked Prisma
message).
- [x] Sampled legitimate 4xx/2xx paths across each pattern variant
(naked-wrap, partial-expanded, 400-preserved) to confirm the wraps don't
interfere with normal control flow.
## Summary
`TriggerChatTransport`, `AgentChat`, and `chat.createStartSessionAction`
now accept a string-or-function `baseURL` so callers can route per
endpoint — e.g. `.in/append` through a trusted edge proxy while keeping
`.out` SSE direct. The same surfaces add a `fetch` override for header
injection, custom retries, or proxy rewrites that go beyond URL routing.
SSE GETs are covered too via a new `fetchClient` option on
`SSEStreamSubscription`.
```ts
// TriggerChatTransport / AgentChat — endpoints: "in" | "out"
baseURL: ({ endpoint }) =>
endpoint === "out" ? DIRECT : PROXY,
fetch: (url, init, ctx) => {
init.headers = new Headers(init.headers);
init.headers.set("traceparent", currentTraceparent());
return globalThis.fetch(url, init);
},
// chat.createStartSessionAction — endpoints: "sessions" | "auth"
chat.createStartSessionAction("my-agent", {
baseURL: ({ endpoint }) => (endpoint === "sessions" ? PROXY : DIRECT),
});
```
`streamBaseURL` on `TriggerChatTransport` is kept as a backwards-compat
alias and continues to win for the `"out"` endpoint when set.
Plain-string `baseURL` still applies to every endpoint, matching prior
behavior.
## Summary
Hot-loop writers — `streams.writer` / `streams.pipe` on the run-scoped
side, `chat.response.write` / `chat.stream.*` on the session side — were
issuing a fresh `PUT` to mint S2 credentials for every chunk. On run
streams, each PUT also pushed the streamId onto
`TaskRun.realtimeStreams`,
so a chat-agent turn writing N chunks produced N PUTs and N duplicate
array pushes against the same row.
The SDK now caches the initialize response per cache slot: `(runId,
key)`
for run streams, the session id for session streams. First call PUTs as
before; subsequent calls reuse the cached promise. Hot-loop writers do
one PUT per slot for the lifetime of the cache.
S2 access tokens have a 1-day TTL. If a writer's `wait()` rejects (auth
error, expired token, network blip), the cache evicts the matching slot
so the next call re-PUTs and mints fresh credentials, identity-checked
so a concurrent caller's fresh promise isn't accidentally cleared.
## chat.agent guardrail
`streams.pipe / writer / append / read` called inside a `chat.agent` run
now logs a one-time warning pointing at `chat.response.write` /
`chat.stream.*` — `streams.*` is run-scoped and isn't visible on the
chat session. The ai-chat docs are updated to drop the old guidance
toward run-scoped streams.
## Summary
- Introduce the Mollifier: a Redis-backed buffer for `trigger()` API
calls during traffic spikes, with a per-env trip evaluator and a drainer
ack-loop.
- Phase 1 is dual-write monitoring — every mollified trigger is buffered
to Redis AND continues to `engine.trigger`. No customer-facing behaviour
change.
- Telemetry events: `mollifier.would_mollify`, `mollifier.buffered`,
`mollifier.drained`, plus the `mollifier.decisions` counter.
- Gated behind a feature flag (default off).
## Test plan
- [x] `pnpm run test --filter @trigger.dev/redis-worker`
- [x] `pnpm run test --filter webapp -- mollifier`
- [x] Manual: with flag off, no behaviour change vs main
- [x] Manual: with flag on + threshold lowered, observe
`mollifier.buffered` + `mollifier.drained` log pairs with matching
`runId`

## Summary
Two papercuts new contributors hit running this repo locally:
1. Fresh clones default to v1 (Redis-only) realtime streams, so Sessions
and `chat.agent` error with `"S2 configuration is missing"`, even though
the `s2` service is already in `docker/docker-compose.yml` and pre-seeds
a `trigger-local` basin. Wire `REALTIME_STREAMS_S2_*` to it in
`.env.example` so the new-contributor flow just works. (Also drop the s2
healthcheck: the image is distroless, so the `wget` check always reports
unhealthy.)
2. Two clones can't both run `pnpm run docker` because ports, project
name, and container names are all hardcoded. Parameterize every host
port as `${VAR:-default}`, drive the project name via
`COMPOSE_PROJECT_NAME` (with a top-level `name:` field as the default),
prefix container names with `${CONTAINER_PREFIX:-}`, and pass
`--env-file .env` so compose reads the same root `.env` the webapp does.
The "Running multiple instances side by side" block in `.env.example`
lists every overridable knob.
Also split the optional services (`electric-shard-1`, `ch-ui`,
`toxiproxy`, `nginx-h2`, `otel-collector`, `prometheus`, `grafana`) into
`docker-compose.extras.yml` behind a new `pnpm run docker:full` script.
The core stack keeps everything the webapp actually needs to boot:
postgres, redis, electric, minio, clickhouse + migrator, s2-lite.
Defaults match every previous hardcoded value, so existing setups keep
working without touching `.env`.
## Test plan
- [x] `pnpm run docker` on a clean clone brings up the core services on
the standard ports under the `triggerdotdev-docker` project name.
- [x] Setting `COMPOSE_PROJECT_NAME=triggerdotdev-docker-alt` + the
`*_HOST_PORT` overrides in `.env` brings up a second stack alongside the
default one with no port or container-name clashes.
- [x] Webapp boots cleanly against the default `.env.example` values;
`/healthcheck` returns 200, no S2 errors.
- [x] s2-lite basin `trigger-local` accepts an append + read via the
same REST endpoints the webapp uses.
- [x] `pnpm run docker:full` brings up the optional services alongside
the core ones in the same project.
## Summary
Long-running chat agents were filling `session.out` forever — every
`chat.agent` turn appended to the same S2 stream with no trim, and the
Sessions dashboard re-streamed the entire history from `seq_num=0` on
every page load. After this change the agent appends an S2 `trim`
command record after each `trigger:turn-complete`, pointing back at the
previous turn-complete's seq_num. `session.out` stays roughly one turn
long at steady state, regardless of session age.
`trigger:turn-complete` and `trigger:upgrade-required` move from
`chunk.type`-shaped data records into header-form control records under
a uniform `trigger-control` namespace. Built-in transports
(`TriggerChatTransport`, `AgentChat`, the dashboard's `AgentView`)
handle the new shape transparently. Custom transports need a one-line
filter on the `trigger-control` header — see the rewritten "Records on
session.out" section in the client-protocol docs.
The Sessions detail page in the dashboard fetches the agent's per-turn
S3 snapshot via a presigned URL and seeds the transcript view, then
SSE-tails from the snapshot's `lastOutEventId`. Bandwidth and
time-to-first-render scale with unread turns instead of session
lifetime.
Resume contract is now explicit: single-turn-boundary resume always
works (the prior turn-complete is still on the stream), the S2 trim is
eventually consistent over 10-60s, and multi-turn-away resume falls back
to a snapshot reload.
## Summary
The PUT handler at `/realtime/v1/streams/:runId/:target/:streamId` ran
`taskRun.update({ realtimeStreams: { push: streamId } })` on every call,
even when the `streamId` was already present. SDK call patterns that
re-initialize the same stream key on every chunk produce a per-write row
UPDATE, duplicate entries pile up in the array, and the row-lock + TOAST
rewrite cost grows unbounded on long-running stream sessions.
## Fix
Mirror the sibling append handler: read the array first and only push
when the `streamId` isn't already present. Identical behavior for
first-time stream creation; repeat creates short-circuit to a single
indexed read. The dashboard's per-run stream listing keeps working
because the first create still records the entry.
## Test plan
- [ ] A fresh PUT for a new `(run, streamId)` adds the entry to the
array
- [ ] A repeat PUT for the same pair leaves the array unchanged
- [ ] 404 is returned when the run doesn't exist; 400 when the run is
completed
## Summary
- Adds a `beforeSend` rule in `apps/webapp/sentry.server.ts` that
collapses Prisma `P1001` ("Can't reach database server") errors into a
single Sentry issue regardless of which call site threw, by setting
`event.fingerprint = ["prisma-p1001-db-unreachable"]` and tagging
`db_unreachable:true`.
- Matches both `err.code === "P1001"` (Prisma's `KnownRequestError` when
a connection drops mid-query) and `err.errorCode === "P1001"`
(`InitializationError` when the client fails to connect at startup).
- Implemented as a small extensible `FINGERPRINT_RULES` table so further
fan-out errors can be added with one entry.
## Verification
End-to-end verified locally with `debug: true` on the SDK:
- Real Prisma `P1001` thrown from a loader (DB stopped mid-request) is
captured by Sentry's Remix auto-instrumentation
- `beforeSend` fires with `originalException.code === "P1001"`, rule
matches
- `event.fingerprint = ["prisma-p1001-db-unreachable"]` and
`tags.db_unreachable = "true"` applied
- Event lands in Sentry under the new fingerprint
## Test plan
- [ ] Deploy to staging; confirm P1001 events appear under a single
`prisma-p1001-db-unreachable` issue rather than fanning out
- [ ] Confirm `db_unreachable:true` tag is filterable in Sentry
- [ ] Verify non-P1001 errors are unaffected (event passes through
`beforeSend` untouched)

## Summary
Local self-hosted deploys (`trigger deploy --local-build --push
--builder orbstack` or any other buildx setup using the **docker**
driver) fail at the push step with:
```
ERROR: failed to build: failed to solve:
exporter option "rewrite-timestamp" conflicts with "unpack"
```
The docker driver auto-enables `unpack=true` when pushing, and that's
incompatible with `rewrite-timestamp` (which the CLI sets for
reproducible-build hashing).
Adds a simple env-var opt-out so contributors can keep using their
default builder. The flag is only read by the local-build code path;
remote/cloud builds are unaffected.
```bash
TRIGGER_BUILD_SKIP_REWRITE_TIMESTAMP=1 \
pnpm exec trigger deploy --profile default --local-build --push --builder orbstack
```
The trade-off: skipping `rewrite-timestamp` means layer timestamps
reflect actual build time, so two identical builds produce different
layer hashes. Fine for a local-dev registry; the only real consumer of
timestamp-stability is registry-layer cache hit rates.
## Test plan
- [x] Manual: ran `trigger deploy --profile default --local-build --push
--builder orbstack` against the localhost webapp + a local Docker
registry on port 5001 — first failed with the rewrite-timestamp/unpack
error, then succeeded after setting
`TRIGGER_BUILD_SKIP_REWRITE_TIMESTAMP=1`.
- [x] Full chat.agent smoke sweep (15 tests, including suspend/resume,
deepResearch subtask, AgentChat orchestrator) against the deployed image
— all pass.
🤖 Generated with [Claude Code](https://claude.com/claude-code)
`TriggerChatTransport` had a single `baseURL` option covering both the
`.in/append` POSTs and the long-lived `.out` SSE subscription. Customers
wanting to route the SSE through a proxy (e.g. a Cloudflare worker
capturing JA4 fingerprints for bot detection) had to send every append
through the proxy too, adding a hop to every user message.
New optional `streamBaseURL` overrides the SSE base URL only; appends
keep using `baseURL`. Falls back to `baseURL` when unset, so existing
transports are unchanged.
```ts
const transport = new TriggerChatTransport({
task: "ai-chat",
baseURL: "https://api.trigger.dev",
streamBaseURL: "https://chat-proxy.example.com",
accessToken,
startSession,
});
```
Verified with a new test in `chat.test.ts` that asserts `.in/append`
routes through `baseURL` and `.out` SSE routes through `streamBaseURL`.
All existing tests still pass.
`dorny/paths-filter` defaults to OR semantics across the pattern array,
so the leading `**` matched every file and the `!...` excludes were
no-ops. The `code` filter has been returning `true` for every PR since
#3615.
Split into two filter steps: `code` moves into its own step with
`predicate-quantifier: every` so excludes actually subtract. The two
re-include workflow files become a separate `typecheck_self` filter that
the `typecheck` job ORs into its `if:`.
Side effect: workflow-file-only PRs that don't touch `pr_checks.yml` or
`typecheck.yml` no longer trigger typecheck. Previously they did because
the filter was broken-true.
## Summary
Codify two rules for ClickHouse migration authors that came out of the
029/030 ordering incident on the TRI-9367 test cloud deploy:
1. **Number files to `max(existing) + 1`, never slot in below the
latest.** Goose runs in strict mode in the cloud deploy pipeline and
refuses to apply a missing version below the current version — slotting
a file in below an already-applied number blocks the next deploy.
2. **DDL must be idempotent** (`ADD COLUMN IF NOT EXISTS`, `DROP COLUMN
IF EXISTS`, `CREATE TABLE IF NOT EXISTS`, etc.) so a retry or
out-of-order apply (`goose up --allow-missing` for local recovery,
manual fixups) is a no-op rather than an error.
## Where the rules live
- `internal-packages/clickhouse/CLAUDE.md` — full rules + example for
migration authors (and AI agents writing migrations).
- `.claude/REVIEW.md` — added a 🔴 finding under "What makes a 🔴
Important finding" so PR reviewers flag either fault as blocking.
The existing migration files are left untouched; the idempotency
requirement applies going forward.
## Test plan
- [ ] Next ClickHouse migration PR uses `IF NOT EXISTS` / `IF EXISTS`
forms
- [ ] No new migration files numbered below an already-applied version
on test/prod
## Summary
Renumber `029_add_task_kind_to_task_runs_v2.sql` →
`031_add_task_kind_to_task_runs_v2.sql` to fix a deploy-blocking
out-of-order migration, and make the DDL idempotent with `ADD COLUMN IF
NOT EXISTS` / `DROP COLUMN IF EXISTS`.
## Root cause
- Migration `030_create_sessions_v1.sql` landed on main on 2026-04-28
(PR #3417) and was applied to test cloud ClickHouse on a subsequent
deploy. Current goose version on test ClickHouse: **30**.
- Migration `029_add_task_kind_to_task_runs_v2.sql` was authored later
on 2026-05-10 as part of the Sessions primitive PR series (`be1a6cf8`).
- The next test cloud deploy failed because goose strict-mode refused to
apply a missing version *before* the current version:
```
goose run: error: found 1 missing migrations before current version 30:
version 29: 029_add_task_kind_to_task_runs_v2.sql
```
## Fix
1. **Rename to `031_*`** (next available number after 030). Goose now
treats it as a new migration after 030 and applies it cleanly on
test/prod where the column does not yet exist.
2. **Make the DDL idempotent** (`ADD COLUMN IF NOT EXISTS`). The
original 029 may have been applied in environments that ran goose with
`--allow-missing` (e.g. some local dev databases) — those would have the
column already, and the rename causes goose to see 031 as new and
re-attempt the ADD. Idempotent DDL keeps that path safe. The `Down`
mirrors with `DROP COLUMN IF EXISTS`.
## Test plan
- [ ] Test cloud deploy (after this lands) successfully runs the
ClickHouse migration step
- [ ] `task_kind` column shows up on `trigger_dev.task_runs_v2`
post-migration
- [ ] Local environments that had previously applied 029 do not error on
the next `goose up`
## Summary
Adds `.changeset/pre.json` to put the repo into changesets pre mode with
dist-tag `rc`. After this merges, the changesets bot regenerates the
existing release PR as `chore: release v4.5.0-rc.0`. Merging that PR
publishes the first release candidate of 4.5.0 to npm under `@rc`.
The pre-mode plumbing landed in #3628. The release content (chat.agent +
sessions + ai prompts + dashboard server-changes) landed in #3629.
## What ships when the bot PR merges
Under dist-tag `rc`:
-
`@trigger.dev/{sdk,core,build,react-hooks,redis-worker,plugins,python,rsc,schema-to-json}@4.5.0-rc.0`
- `trigger.dev@4.5.0-rc.0`
Plus:
- Docker image `ghcr.io/triggerdotdev/trigger.dev:v4.5.0-rc.0`
(immutable tag only — `:v4-beta` is not touched)
- Helm chart `oci://ghcr.io/triggerdotdev/charts/trigger.dev:4.5.0-rc.0`
- GitHub release `v4.5.0-rc.0` marked as Pre-release (no Latest badge)
What does NOT happen:
- npm `latest` stays at 4.4.6
- No marketing-site changelog PR (gated on `is_prerelease != 'true'`)
- Docker `:latest` not touched (we never push it anyway in this repo)
## Iteration
For subsequent rc.N: add a regular changeset to main, bot regenerates
the release PR as `v4.5.0-rc.N`. Merge to ship.
## Exiting pre mode
When ready to ship stable: `pnpm exec changeset pre exit`, push, merge
regenerated PR. That publishes `4.5.0` under `latest` and fires the
marketing-site dispatch.
## Summary
Refocuses the v4.5.0 changeset and server-changes content on the
public-facing AI features story, replacing the pre-release-internal diff
framing that had accumulated in `.changeset/` and `.server-changes/`.
Pairs with the RC support PR — the next bot regeneration will pick up
this content.
## What's in here
### Changeset rewrites
- **`chat-agent.md` rewritten as the headline AI Agents entry** —
written from the `docs/ai-chat/` surface (not from internal pre-release
diffs). Covers useChat integration, multi-turn durability via Sessions,
lifecycle hooks, stop generation, tool approvals (HITL), pending
messages + background injection, actions, typed state primitives,
`chat.toStreamTextOptions()`, multi-tab coordination, network
resilience, and the first-turn fast path (`chat.headStart`).
- **New `ai-prompts.md`** — announces the Prompts feature publicly for
the first time. Code-defined templates, deploy-versioning, dashboard
overrides, AI SDK telemetry integration, `chat.agent` integration via
`chat.prompt.set()` + `chat.toStreamTextOptions()`, full management SDK.
- **`sessions-primitive.md` expanded** — calls out
`tasks.triggerAndSubscribe()` and `sessions.list` as standalone
primitives (not just chat.agent infrastructure).
- **`chat-agent-on-boot-hook.md` trimmed** — drops "if you previously…"
pre-release migration framing.
- **Deletes 4 changesets** that described pre-release-internal
migrations or were circular ("groundwork for the upcoming chat.agent" —
chat.agent ships in the same release).
### Server-changes rewrites (`.server-changes/`)
Five new entries for the dashboard surface of the AI feature set:
- Agents list page
- Agent Playground
- Sessions dashboard
- Prompts dashboard (list with usage sparklines + detail with template /
Generations / Metrics / Versions tabs + override UI)
- Models registry (provider-grouped catalog with cross-tenant usage
metrics)
- AI generation span inspector on run traces
- Runs list Task source filter (Standard / Scheduled / Agent)
- Run-detail Agent view (segmented control)
Each entry is 1–2 sentences, no bullets, no implementation file paths —
fits as a single bullet in a future changelog.
Three older `.server-changes/` files were merged or split into the
cleaner taxonomy above and deleted.
## Out of scope
Non-AI-feature server-changes (admin-tabs, queue-length-cap fix,
worker-deployment race, streamdown upgrade, etc.) and changesets
(idempotency-key cap, sigsegv retry, locals-key fix, plugin auth, region
filters, etc.) are untouched.
## Summary
Enables shipping `X.Y.Z-rc.N` prereleases of `@trigger.dev/*` via
changesets pre mode. RCs publish under the `rc` npm dist-tag, never
claim `latest`, and don't trigger marketing-site changelog PRs. The
plumbing is hyphen-in-version detection in `release.yml` — no separate
workflow, no opt-in flag at publish time.
Validated end-to-end against a sandbox repo (real npm publishes, Docker
builds, Helm chart pushes, GitHub releases) before porting back. Full RC
lifecycle tested: pre enter → rc.0 → iterate to rc.1 → pre exit →
stable. Plus interaction with the existing release-branch hotfix flow.
## What changes
### `release.yml`
- New `is_prerelease` output (hyphen-in-version)
- GitHub release adds `--prerelease` flag for RC publishes (Pre-release
badge, not Latest)
- `dispatch-changelog` job gated on `is_prerelease != 'true'` — no
marketing-site PR per RC
### Docker workflows
- Removes the `:v4-beta` floating tag entirely from `publish-webapp.yml`
and `publish-worker-v4.yml`. v4 is GA; the tag is a misnomer and is
already inconsistent with the npm side (npm `v4-beta` dist-tag was
frozen at 4.0.4 months ago while Docker `:v4-beta` kept bumping).
Self-hosters should pin to a versioned tag going forward — the last
value of `:v4-beta` stays frozen wherever it currently points.
### CLI version-check fix
(`packages/cli-v3/src/utilities/initialBanner.ts`)
Switches the "new version available" comparison from JavaScript
`localeCompare` to `semver.lt`. The old comparison handled `X.Y.Z-rc.N`
vs `X.Y.Z` incorrectly — a user on `4.5.0-rc.0` would never be prompted
to upgrade once `4.5.0` stable shipped (lex order put the prerelease
ahead of the bare version). Real semver gets this right.
Stable users were never affected: the check queries the `@latest`
dist-tag, which by convention never points at a prerelease.
## How an RC actually publishes after this
1. `pnpm exec changeset pre enter rc` on main, push the `pre.json`
2. Bot regenerates the release PR as `chore: release v<X.Y.Z>-rc.0`
3. Merge → `release.yml` runs `changeset publish` which reads
`pre.json.tag` and publishes under `--tag rc`. GitHub release marked
Pre-release. No marketing-site dispatch.
4. Iterate by adding changesets normally; bot bumps to `rc.1`, `rc.2`, …
5. When ready: `pnpm exec changeset pre exit`, push, merge regenerated
PR → stable ships under `latest` and the marketing-site dispatch fires.
## Summary
Adds a Region column and Region filter (under More filters) to the runs
list dashboard, the same filter on the public runs list API
(`filter[region]`), and a matching `region` input on the MCP `list_runs`
tool. Each run's executing region is also surfaced as a new optional
`region` field on the runs list and run retrieve responses, populated
from the worker instance group's `masterQueue` identifier.
Useful when you run tasks across multiple regions and want to slice the
runs list — or your existing run-querying scripts — by where the run
actually executed.
## Design
The filter value in the URL / API is the `masterQueue` identifier (the
same string already persisted on `TaskRun` and replicated to ClickHouse
as `worker_queue`), so the query just becomes `worker_queue IN (...)`
with no server-side translation. The Region dropdown options come from a
new resource loader backed by `RegionsPresenter`, which now also exposes
`masterQueue` alongside the existing region metadata.
```ts
// public API
const runs = await runs.list({ region: ["us-east-1", "eu-west-1"] });
// each item: { id, status, ..., region?: "us-east-1" }
```
```ts
// MCP
list_runs({ environment: "prod", region: "us-east-1" })
```
## Summary
The trigger-task hotpath used to early-return without a DB query when a
caller passed both a queue override and a per-trigger TTL — the hottest
configuration on the trigger API. Adding `triggerSource` to the resolver
so the runs-list "Source" filter could distinguish STANDARD / SCHEDULED
/
AGENT runs removed those early-returns, costing +2 DB queries per
trigger
on non-locked calls and +1 on locked calls.
This change caches `BackgroundWorkerTask` metadata (`ttl`,
`triggerSource`,
`queueId`, `queueName`) in Redis so the resolver can satisfy every
caller
configuration with a single `HGET` on the warm path. PG fallback on miss
back-fills the cache.
Follow-up to #3542.
## Design
Two key spaces:
- `task-meta:env:{envId}` — the "current worker" view, refreshed at
every
deploy promotion. 24h safety TTL.
- `task-meta:by-worker:{workerId}` — used for `lockToVersion` triggers.
Immutable post-create. 30d sliding TTL so historical workers age out.
Cache writes use Lua scripts via `defineCommand` so `DEL` + `HSET` +
`EXPIRE` land atomically — concurrent readers never see the empty
intermediate state of a naive pipeline. Read-path back-fill uses
single-field upserts so concurrent back-fills don't wipe each other's
siblings.
The cache lives behind its own `TASK_META_CACHE_REDIS_*` env-var prefix
that falls back to the default `REDIS_*` set, so operators can route the
cache to a dedicated Redis instance if they want.
The service/instance file split (`taskMetadataCache.server.ts` for the
pure class, `taskMetadataCacheInstance.server.ts` for the env-wired
singleton) mirrors the existing `runsReplicationService` /
`runsReplicationInstance` pattern.
## Test plan
- [ ] `pnpm run typecheck --filter webapp`
- [ ] `pnpm run test ./test/engine/triggerTask.test.ts --run` — 8
existing tests untouched + 5 new tests covering warm cache, cold
miss with back-fill, queue + ttl path, by-worker vs env keyspace,
and the promotion cache write
- [ ] End-to-end against a dev worker: registering writes both keyspaces
with the expected TTLs, and `redis-cli HGETALL
"tr:task-meta:env:<envId>"`
returns the cached entries
## Benchmark
Measured `DefaultQueueManager.resolveQueueProperties` against a real
Postgres + Redis (vitest `containerTest`, single-host docker). 500
sequential calls and 2,000 parallel calls (concurrency=50) per scenario,
request shaped as `{ taskId, queue: "bench-queue", ttl: "5m" }` — the
hot path this PR restores.
```
sequential (one in flight at a time):

speedup (warm vs baseline, sequential): 16.95x
parallel (concurrency=50):

throughput speedup (warm vs baseline, parallel): 16.27x
```
Read:
- **Warm cache cuts resolver latency 17×** at p50 — from ~1.4 ms to ~78
µs per call.
- **Cold cache is on par with baseline** — the extra `HGET` miss adds
<50 µs against the two Postgres queries that follow, so the worst case
is not worse than today.
- **Under burst load (50 concurrent triggers)**, the baseline's p99
jumps to ~32 ms as Postgres connections queue up; warm stays at ~1.4 ms.
The cache moves the saturation point from ~5k ops/s (PG pool) to ~80k
ops/s (single-client Redis pipelining).
Caveats: single-host docker, local Postgres + Redis, resolver-only
measurement (excludes the rest of the trigger transaction). Prod adds
region-local Redis RTT (~0.3–0.8 ms) which shifts warm absolute numbers
up but keeps the ratio intact.
## Summary
A "Google auth conflict" Sentry alert fires whenever a user signs in via
Google whose Google account is linked to one user row but whose
Google-provided email is now on a *different* user row. The handler in
`apps/webapp/app/models/user.server.ts:236` already does the right thing
— it returns the existing auth-linked user and skips the update path so
neither row gets mutated — but it logs the situation with
`logger.error`, which routes to Sentry as an exception and pages the
on-call channel.
There's no exception to chase here: the branch is the intended outcome
for a known data shape (user changed their email on one account after
originally signing up via Google on another). Downgrading the call to
`logger.warn` keeps the diagnostic record in our logs (with all the same
context fields — email, both user IDs, authIdentifier) but stops it
firing the production error alert.
## Change
- `logger.error` → `logger.warn` for the conflict branch in
`findOrCreateGoogleUser`. Context payload is unchanged.
## Test plan
- [x] Typecheck only — there's no behavioural change to test, the log
level is the entire diff.
## Summary
`LocalsKey<T>` (the type returned by `locals.create()`) was branded with
a
module-level `declare const __local: unique symbol`. Each such
declaration
is its own nominal type, and `tshy` emits separate `.d.ts` files for the
ESM and CJS outputs — each gets its own `__local` symbol. Under certain
pnpm hoisting layouts a single TypeScript compilation can resolve
`LocalsKey` from both the ESM source path and the CJS dist path within
the same call site, producing two structurally-incompatible variants of
the same type. TS surfaces this as the misleading error:
```
Argument of type 'LocalsKey<X>' is not assignable to parameter of type
'LocalsKey<X>'. Property '[__local]' is missing in type 'LocalsKey<X>'
but required in type 'BrandLocal<X>'.
```
The error has been hitting CI on PRs opened since the chat.agent stack
landed (e.g. #3625 typecheck job), but doesn't reproduce on developer
machines where the pnpm node_modules layout was built up incrementally.
## Fix
Replace the `unique symbol` brand with an optional phantom field that
carries `T` at the type level:
```ts
// before
declare const __local: unique symbol;
type BrandLocal<T> = { [__local]: T };
export type LocalsKey<T> = BrandLocal<T> & {
readonly id: string;
readonly __type: unique symbol;
};
// after
export type LocalsKey<T> = {
readonly id: string;
readonly __type: symbol;
/** Phantom carrier for the value type — never read at runtime. */
readonly __valueType?: T;
};
```
The ESM and CJS `.d.ts` outputs now produce structurally identical
types,
so cross-output resolution no longer produces a mismatch. `T` is still
carried at the type level via the optional phantom field. The runtime
shape is unchanged — `manager.ts` was already casting via `as unknown`,
which is no longer needed.
## Test plan
- [ ] `pnpm run typecheck --filter @trigger.dev/core --filter
@trigger.dev/sdk`
- [ ] `pnpm run build --filter @trigger.dev/core --filter
@trigger.dev/sdk`
(clean rebuild) — confirms the ESM and CJS dist `.d.ts` outputs
no longer carry distinct `unique symbol` declarations
- [ ] `pnpm --filter @trigger.dev/core test test/mockTaskContext.test.ts
--run`
- [ ] `pnpm --filter @trigger.dev/sdk test test/mockChatAgent.test.ts
--run`
Follow-up to #3615. The `code` filter currently fires typecheck for any
change outside `docs/`, `.changeset/`, `hosting/`, or `.github/` - so a
docs-only PR like #3623 (touching `references/ai-chat/.env.example` +
`README.md`) triggered the typecheck job. None of the `references/*`
packages declare a `typecheck` script either, so even when a real code
change lands there, `turbo run typecheck` skips them. Running the job is
pure cost.
Tightens the filter to also exclude:
- `references/**` - playground projects, none of them contribute to
`turbo run typecheck` today
- `**/*.md` - markdown anywhere
- `**/.env.example` - example env files anywhere
Two known gaps left open:
- references/ have no real CI typecheck coverage. Separate question -
either add `typecheck` scripts to each (or top-level `tsc -p`), or
accept playground status.
- `changes` job still runs (it's a path-filter step) but the dependent
jobs all skip on irrelevant PRs.
## Summary
A complete Next.js reference project that exercises `chat.agent`
end-to-end, plus the CLI MCP tools that let Claude Code, Cursor, and
similar IDE agents drive a deployed `chat.agent` task from the editor.
Builds on #3545.
## Design
`references/ai-chat` is a full Next.js app: prisma-backed persistence,
multi-chat sidebar, per-chat model picker, debug panel, tool examples
(`getCurrentTime`, `searchHackerNews`, `createGithubIssue`, PR review
helpers, code sandbox), and smoke tests. It's intended both as a
copy-paste starting point and as a place to regression-test SDK changes.
The CLI gains MCP tools (`start_agent_chat`, `send_agent_message`,
`close_agent_chat`, `list_agents`) so an IDE agent can converse with a
deployed `chat.agent` task. The dev runtime adds one-shot OOM kill on
the run controller and skills bundling in the build pipeline.
Top of the chat.agent stack: a full Next.js reference project that

fix(cli): preserve lastEventId after sendMessage fallback to avoid stale turn-complete replay
## Summary
A chat-aware run inspector and a `/playground` UI for testing
`chat.agent` tasks interactively. Builds on #3543's runtime.
## Design
The run inspector grows a new tab that renders the conversation chain
for any `chat.agent`-kind run. It subscribes to the run's session
streams, threads chat parts through a per-message renderer, and uses a
shared markdown + Shiki component for code highlighting (also used by
the test-payload panel).
The playground is a standalone `/playground` route that lets you drive a
deployed chat agent from the dashboard — pick a task, send messages,
watch tool calls render, and see span detail on every turn. The matching
`/agents` list view shows all deployed agents in the project.
Concurrent `POST /api/v1/deployments` requests for the same environment
race on the `WorkerDeployment(environmentId, version)` unique
constraint. Both requests read the same latest deployment via
`findFirst`, compute the same next version via
`calculateNextBuildVersion`, and both attempt
`prisma.workerDeployment.create()` — one wins, the other crashes with
Prisma `P2002`. The bug is a classic TOCTOU between the version read and
the version write; it's been latent since the version-assignment logic
was first added but only fires when two deploys land within milliseconds
of each other (CI matrices, retried CLI calls, webhook-triggered
redeploys).
## Approach
Extracts the version assignment + create into a small helper
`createDeploymentWithNextVersion`
(`apps/webapp/app/v3/services/initializeDeployment/createDeploymentWithNextVersion.server.ts`).
The helper retries on `P2002 (environmentId, version)` up to 5 times
with randomised 5–50ms jitter so N concurrent racers don't loop in
lockstep. Each attempt re-reads the latest version, recomputes via
`calculateNextBuildVersion`, and re-runs the caller's `buildData`
callback so version-dependent fields (image ref tag, friendlyId) are
always consistent with the version actually persisted. A `logger.warn`
fires per collision so the retry rate is observable in production logs.
When retries are exhausted, the helper throws a dedicated
`DeploymentVersionCollisionError` carrying `environmentId`, `attempts`,
and `lastAttemptedVersion`, with the original
`PrismaClientKnownRequestError` attached as `cause`. Sentry walks the
`cause` chain natively, so contention exhaustion shows up as a
distinguishable wrapper exception linked to the underlying `P2002`
rather than a generic unique-constraint violation that looks identical
to every other duplicate-key bug.
The behavioural change is limited to "catch P2002 and retry instead of
crashing." The image ref computation stays inside the builder callback
(same call site as before the refactor), so ECR / non-ECR behaviour, S2
stream creation order, and all downstream side effects are unchanged.
## Non-goals
- No new database migrations, no schema changes, no isolation-level /
locking changes. A serialisable transaction or advisory lock would also
fix this; retry-on-conflict is the smaller change that keeps the
existing version-allocation logic intact.
- Does not touch the analogous `calculateNextBuildVersion` call in
`createBackgroundWorker.server.ts`, which likely has the same race shape
against `BackgroundWorker`'s unique constraint — flagged as a follow-up.
## Test plan
- [x] `pnpm run typecheck --filter webapp` passes (no new errors in the
modified files).
- [x] Three real-Postgres tests in
`apps/webapp/test/createDeploymentWithNextVersion.test.ts` via
`containerTest`:
- 5 concurrent calls all produce distinct, persistable versions
(`Set(versions).size === concurrency`). The naive read-then-create
version of the helper fails this test with the exact same `P2002` seen
in production; the retry version passes.
- Non-`P2002` errors raised from the `buildData` callback propagate
immediately without retry, builder invoked exactly once.
- With `maxRetries: 0`, concurrent racers surface the wrapped
`DeploymentVersionCollisionError` (not a raw `P2002`); `environmentId`,
`attempts`, `lastAttemptedVersion` are populated and `error.cause.code
=== "P2002"`.
- [x] Existing `apps/webapp/test/getDeploymentImageRef.test.ts` still
green (the file was untouched in the final diff).
## Follow-ups (not in this PR)
- `createBackgroundWorker.server.ts` likely has the same TOCTOU shape
against its background-worker version unique constraint — should use the
same helper.
- Sentry visibility check: confirm `error.cause` chain renders as a
linked exception in the Sentry UI when the wrapped error fires (requires
a sandboxed triggering of the exhaustion path).

## Summary
Adds `chat.agent({...})`, a durable conversational task runtime, plus
the browser-side `TriggerChatTransport` + `AgentChat` that drive it from
a React or Next.js app. Conversations survive page refreshes, network
blips, idle suspend, and process restarts, with built-in tools, HITL
approvals, multi-turn state, and stop-mid-stream cancellation. Builds on
#3542.
## Design
Each `/in/append` request carries at most one new message. The agent
reconstructs prior history at run boot from an object-store snapshot
plus a `session.out` replay tail, so conversation context lives
server-side instead of bloating the wire. Awaited snapshot writes after
every `onTurnComplete` keep the chain durable across idle suspend.
Registering `hydrateMessages` short-circuits both paths for customers
who own their own conversation store.
Lifecycle hooks — `onChatStart`, `onTurnStart`, `onTurnComplete`,
`onAction`, `onValidateMessages`, `hydrateMessages` — cover validation,
persistence, and post-turn work. `chat.history` exposes read primitives
(`getPendingToolCalls`, `getResolvedToolCalls`, `extractNewToolResults`,
`findMessage`, `all`) for HITL flows. `chat.local` gives per-run typed
state with Proxy access and dirty tracking. `chat.headStart` bridges
first-turn TTFC via a customer HTTP handler. `oomMachine` opts a chat
into one-shot OOM-retry on a larger machine.
`TriggerChatTransport` is a `Transport` implementation for Vercel's
ai-sdk `useChat`: delta-only wire sends, SSE reconnection with
`lastEventId` resume, stop/abort cleanup, dynamic `accessToken` refresh,
`X-Peek-Settled` fast-close. `AgentChat` is the direct programmatic
equivalent. A cross-tab coordinator does leader election so multiple
open tabs share a single SSE.
```ts
import { chat } from "@trigger.dev/sdk/ai";
import { streamText } from "ai";
export const myChat = chat.agent({
id: "my-chat",
run: async ({ messages, signal }) =>
streamText({ model: openai("gpt-4o"), messages, abortSignal: signal }),
});
```
Adds the chat.agent({...}) task definition (server runtime) and the
browser-side TriggerChatTransport + AgentChat that drives it from a
React or Next.js app. The runtime sits on top of the Sessions primitive
and handles the durable conversational task lifecycle.
Server runtime:
- chat.agent({...}) — session-aware task definition
- Lifecycle hooks: onChatStart, onTurnStart, onTurnComplete, onAction,
onValidateMessages, hydrateMessages
- chat.history read primitives for HITL flows
- chat.local, chat.headStart, chat.handover, oomMachine
- Delta-only wire + S3 snapshot reconstruction at run boot
- Actions are no longer turns
Browser transport:
- TriggerChatTransport (ai-sdk Transport): delta-only wire sends,
SSE reconnection with lastEventId resume, stop/abort cleanup,
dynamic accessToken refresh
- AgentChat: direct programmatic API
- useTriggerChatTransport (React hook)
- chat-tab-coordinator: cross-tab leader election
Includes the chat-agent, chat-agent-delta-wire-snapshots,
chat-history-read-primitives, chat-head-start, chat-actions-no-turn,
chat-session-attributes, agent-skills, and mock-chat-agent-test-harness
changesets.
Adds a Mon 08:00 UTC workflow that posts a summary of open Dependabot
alerts and PRs to Slack. Uses env-scoped secrets so the alerts PAT and
Slack token are only available to this workflow.
The `code` paths filter currently matches `**` minus a tiny exclusion
list, so a PR that only touches `.github/workflows/*.yml` still flips
`code == true` and runs typecheck (~2 min on the runner).
Exclude `.github/**` from `code`, then re-include just `pr_checks.yml`
and `typecheck.yml` so a change to either of those still triggers the
full code check matrix.
Effect:
- workflow-only PRs (this one, future dependabot/codeql/etc.) skip
typecheck; `all-checks` treats the skipped job as non-failure so the
required status passes.
- modifying `pr_checks.yml` or `typecheck.yml` themselves still triggers
typecheck.
- the existing per-suite filters (`webapp`, `packages`, `internal`,
`cli`, `sdk`) already re-include the specific workflows that gate them,
so they're unaffected.
## Summary
A `/sessions` dashboard for inspecting durable Sessions, an `AGENT` /
`SCHEDULED` task-kind filter for the runs list, and the server-side
hardening (rate-limit exemption for packets, retry-with-backoff on
stream appends, typed too-large-chunk error) that the `chat.agent`
runtime in #3543 needs. Builds on the Sessions primitive shipped in
#3417.
## Design
The Sessions list + detail routes mirror the run inspector pattern.
`TaskTriggerSource` gains `AGENT` and `SCHEDULED` values, persisted on
`BackgroundWorker.taskKind` and `TaskRun.taskKind` (plus a matching
Clickhouse column), so the runs list can filter by kind.
New `@trigger.dev/core` modules — `sessionStreams`, `inputStreams`, a
`sessionStreamInstance` for realtime streams, and the
`realtime-streams-api` / `session-streams-api` surfaces — expose the
typed shapes that chat.agent will use to drive `session.out`.
`ChatChunkTooLargeError` lets the runtime drop oversized chunks with a
typed surface instead of failing the run. `s2Append` retries transient
failures with exponential backoff. `/api/v[12]/packets/*` is exempt from
customer rate limits so chat snapshot reads and writes don't get
throttled under load.

`tasks.trigger`, `tasks.batchTrigger`, `batch.create`,
`wait.createToken`, `wait.forDuration`, and the input/session stream
waitpoint endpoints all accept a caller-supplied `idempotencyKey` and
store it verbatim against a composite-unique index on `TaskRun`,
`BatchTaskRun`, or `Waitpoint`. The schemas had no length cap, so a
sufficiently long high-entropy key produced an index row larger than the
underlying storage layer can hold. The insert failed at the database,
and the caller saw a generic 500 from
`RunEngineTriggerTaskService.call()` / `CreateBatchService` / waitpoint
creation, depending on the endpoint.
Keys produced by `idempotencyKeys.create()` are 64-character SHA-256
hashes and never trip this — it only manifests for direct REST callers
(or SDK callers passing a raw string they generated themselves).
Low-entropy keys also sail through, because the storage layer compresses
repeated bytes before they reach the index, which is why the failure
mode is intermittent and tied to caller-side key shape.
## Fix
Add `.max(2048, "<field> must be 2048 characters or less")` to the seven
schemas that feed an indexed `idempotencyKey` column:
- `TriggerTaskRequestBody.options.idempotencyKey`
- `BatchTriggerTaskItem.options.idempotencyKey`
- `CreateBatchRequestBody.idempotencyKey`
- `CreateWaitpointTokenRequestBody.idempotencyKey`
- `CreateInputStreamWaitpointRequestBody.idempotencyKey`
- `CreateSessionStreamWaitpointRequestBody.idempotencyKey`
- `WaitForDurationRequestBody.idempotencyKey`
Plus the `idempotency-key` HTTP header on the trigger route (and the
three batch routes that re-export `HeadersSchema`). The header schema is
lifted out of `api.v1.tasks.$taskId.trigger.ts` into
`apps/webapp/app/v3/triggerHeaders.server.ts` so it can be exercised in
tests without dragging the route's import-time side effects.
The 2048 character ceiling is chosen to sit safely under the per-row
index limit while staying generous against existing callers — keys that
fit before still fit. Oversized keys now return a structured Zod 400
instead of a generic 500.
Limit is documented under `Idempotency key` in `docs/limits.mdx` and as
a `<Note>` on `docs/idempotency.mdx`.
## Test plan
- [x] 15 schema unit tests added
(`packages/core/src/v3/schemas/idempotencyKey.test.ts`,
`apps/webapp/test/routes/triggerHeaders.test.ts`) —
rejection-with-message + boundary acceptance for each capped schema. The
webapp test exercises the extracted `TriggerHeadersSchema` directly with
no mocks.
- [x] `pnpm run build --filter @trigger.dev/core`
- [x] `pnpm run typecheck --filter webapp`
- [x] End-to-end verified locally: baseline (small key) → 200; 3000-char
high-entropy header → 400 with the expected Zod error; same key at the
2048 boundary → 200; same key with the cap reverted → the database
rejected the insert and the route returned 500 to the caller. Cap
restored.

Adds Sessions, a durable, run-aware stream primitive that scopes
session.in / session.out records to a session (not a single run).
Records survive run boundaries; reconnect-from-last-event-id is built in.
Server foundation:
- New /realtime/v1/sessions/:session/:io/append + /records routes
- sessionRunManager + sessionsRepository + clickhouseSessionsRepository
- mintRunToken for short-lived per-session tokens
- s2Append retry-with-backoff + undici cause diagnostics
- /api/v[12]/packets/* exempt from customer rate limits
- BackgroundWorker schema gains taskKind enum (TASK, AGENT, SCHEDULED)
- TaskRun.taskKind column + clickhouse 029_add_task_kind_to_task_runs_v2
Core types:
- new sessionStreams, inputStreams, realtimeStreams packages in @trigger.dev/core
- session-streams-api / realtime-streams-api surface
Sessions dashboard UI (the primitive's own viewer):
- /sessions index + detail routes
- SessionsTable, SessionFilters, SessionStatus, CloseSessionDialog
- AGENT/SCHEDULED filter in RunFilters + TaskTriggerSource
Includes the sessions-primitive changeset.
Switching between the Users and Organizations tabs in the admin
dashboard now keeps the current `?search=` value, so you can flip
between the two without re-typing your filter. Other admin tabs don't
take `search` and so don't carry it.
`pr_checks` runs the full matrix on every PR. #3609 touched only
`apps/webapp/app/routes/admin.tsx` and still ran the 4-job CLI e2e
matrix and 5-job sdk-compat suite.
Adds a `changes` job using `dorny/paths-filter` and gates each tier:
- webapp + e2e-webapp: `apps/webapp/**`, `packages/**`,
`internal-packages/**`
- packages: `packages/**`
- internal: `internal-packages/**` + `packages/**` (cross-deps)
- e2e (cli-v3): `packages/{cli-v3,build,core,schema-to-json}/**`
- sdk-compat: `packages/{trigger-sdk,core}/**`
`.configs/**`, `package.json`, `pnpm-lock.yaml`, `pnpm-workspace.yaml`,
`turbo.json` are also included in every filter since they affect the
whole workspace.
Inlines the `units` reusable-workflow children so each can be gated
independently (status check names also flatten from `units / webapp /
...` to `webapp / ...`). `unit-tests.yml` is unaffected - still used by
`publish.yml`.
Adds an `all-checks` gate that always runs and short-circuits to success
when every dependent is success-or-skipped. With this in place a single
required status check (`All PR Checks`) is enough; before this,
`paths-ignore` would have left required checks Pending on docs/changeset
PRs ([gh
docs](https://docs.github.com/en/actions/managing-workflow-runs/skipping-workflow-runs)).
## Summary
- Recommend deploying NodeLocal DNS and lowering `ndots` to `1` in the
Kubernetes self-hosting guide.
- Recommend storing task events in ClickHouse
(`EVENT_REPOSITORY_DEFAULT_STORE=clickhouse_v2`) in both the Docker and
Kubernetes guides, plus a new row in the webapp env var reference.
## Summary
- Users on production are hitting `QuotaExceededError: Failed to execute
'setItem' on 'Storage'` when navigating runs, because their localStorage
is full of orphaned `panel-group-react-aria<n>-:<rid>:` entries.
- Each entry is a session-unique key written by the resizable panel
library; they accumulated to thousands per user over the last two months
and now block legitimate `setItem` calls (the run-view inspector can no
longer persist its layout, and the page crashes mid-render).
- This PR evicts the legacy entries once on client boot. The leak itself
is already plugged by the v1.1.3 upgrade in #XXXX — this is the cleanup
that recovers the wasted quota on existing users' machines.
## Root cause (already fixed, for context)
In v0.4.1 of the underlying library, `PanelGroupImpl` defaulted
`autosaveStrategy` to `"localStorage"` unconditionally — so *every*
`PanelGroup` wrote to localStorage on every autosave trigger, including
the four in `QueryEditor`, the one in `ReplayRunDialog`, the storybook
routes, etc. Without an `autosaveId`, the key fell back to
`panel-group-${useId()}`, and React Aria's `useId()` produces a new
session-unique prefix each visit. Result: entries accumulated without
bound across sessions.
The condition was introduced when
[#3282](https://github.com/triggerdotdev/trigger.dev/pull/3282) removed
the wrapper's explicit `autosaveStrategy="cookie"` override (to fix HTTP
431 cookie-size errors). That worked, but the library default that took
over silently caused this leak.
The v1.1.3 upgrade in the resizable-panel PR changed the default to
`autosaveStrategy = autosaveId ? "localStorage" : undefined`, so no new
entries are being written. Existing residue still needs to be removed
from users' browsers.
## Changes
- New file
[`apps/webapp/app/clientBeforeFirstRender.ts`](apps/webapp/app/clientBeforeFirstRender.ts)
— exports a `clientBeforeFirstRender()` function that runs
synchronously, before React hydrates. Encapsulates a small cleanup
helper that scans `localStorage` and removes:
- Every key starting with `panel-group-react-aria` (the legacy
auto-generated keys).
- The orphan `panel-run-parent-v2` key from before the autosaveId v2→v3
bump.
- [`apps/webapp/app/entry.client.tsx`](apps/webapp/app/entry.client.tsx)
— imports and invokes `clientBeforeFirstRender()` once, before
`hydrateRoot()`. This guarantees the cleanup completes before any
`ResizablePanelGroup` mounts and tries to write.
The cleanup is wrapped in `try/catch` so private-browsing /
disabled-storage scenarios fail silently. Idempotent: subsequent loads
find no matching keys and exit immediately.
## Test plan
- [x] Locally seed ~50 fake `panel-group-react-aria…` entries plus a
`panel-run-parent-v2` entry via DevTools console, hard reload → legacy
entries gone, real entries (`panel-run-parent-v3`, `panel-run-tree`)
preserved.
- [x] Idempotency: reload a second time, no errors, no state changes.
- [x] Add a control entry (`panel-run-parent-v3-but-different-suffix`) —
confirmed not over-matched.
- [x] Simulate broken `Storage.setItem` throwing — page still renders,
cleanup swallows the error.
- [x] Typecheck clean.
## Notes
- Customer report: `QuotaExceededError: Failed to execute 'setItem' on
'Storage': Setting the value of 'panel-run-parent-v3' exceeded the
quota.`
- The cleanup runs once per page load. Once a user has loaded the app
after this deploys, their localStorage is clean and the function becomes
a no-op forever.
## Summary
Follow-up to #3561. The drift-audit workflow timed out on PR #3542 (92
files, +5962 lines) by hitting `--max-turns 15` before reaching a
verdict, leaving a red ❌ on that PR with no sticky comment.
## Changes
- `--max-turns` bumped from 15 to 30.
- Prompt now opens with an explicit "Strategy" section: read REVIEW.md
once, scan the file-list only, open at most 5 files (3-5 on PRs >50
files), and bias toward finishing over exploring.
- Final rule: *"when in doubt between one more file read and finish now
— finish now."*
The audit is allowed to miss things. It is not allowed to time out and
leave a red X.
## Test plan
- [ ] Verify this PR's audit posts `✅ REVIEW.md looks current for this
PR.` (small diff)
- [ ] After merge, retry the audit on #3542 or a similarly large PR and
confirm it completes
## Summary
Local ClickHouse was burning ~325% CPU endlessly merging its own
telemetry tables (`metric_log`, `asynchronous_metric_log`, `part_log`,
`trace_log`) after the container had been running long enough to
accumulate hundreds of GB of system-log data. OrbStack Helper reflected
this on the host (~400% CPU).
These tables are not used by anything in the dev stack. They only exist
for ClickHouse to log itself, so disabling them eliminates the merge
churn entirely.
## Changes
- Adds `docker/config/clickhouse-disable-system-logs.xml`, mounted into
`/etc/clickhouse-server/config.d/`, that removes the noisy system log
tables via `<table remove="1"/>`.
- Mounts the override file in `docker/docker-compose.yml`.
After applying, idle CPU dropped from 325% to ~12% on my machine.
## Test plan
- [ ] `pnpm run docker` brings up the stack cleanly
- [ ] `docker stats clickhouse` shows low idle CPU
- [ ] App functionality unaffected (system log tables are not queried by
the webapp)
## Summary
Queues that use concurrency keys can no longer bypass the per-queue
length cap, and the "Queued | Running" columns in the dashboard now show
the true total across all CK variants instead of 0.
The cap and the dashboard both relied on `ZCARD` of the base queue key,
but CK-keyed runs live under `<base>:ck:<variant>` keys. Any queue that
used concurrency keys read 0 — letting a single CK variant grow
unbounded past the user's configured cap.
## Fix
Two per-base-queue counters are maintained inside the CK Lua scripts:
`<base>:lengthCounter` and `<base>:runningCounter`. Non-CK
enqueue/dequeue paths are untouched.
Counters are lazy-initialized the first time a CK enqueue (or nack)
lands on a queue: the Lua script sums `ZCARD` across the variants
tracked by `ckIndex`, sets the counter, then `INCR`s. Pre-existing CK
backlog on already-populated queues is captured automatically — no batch
migration required.
`INCR`/`DECR` is gated on `ZADD`/`SADD` returning 1 (a new entry vs an
idempotent no-op), so duplicate enqueues or re-dequeues don't inflate
the counter.
The counter is `SET` with a 24-hour TTL on init. `INCR`/`DECR` do not
extend the TTL, so the counter expires daily and the next CK operation
re-seeds it from `ckIndex`. This bounds any drift that accumulates
during the rolling-deploy overlap window — where old (un-Tracked) and
new (Tracked) webapp instances briefly coexist — to ≤24 hours, with no
admin sweep or background reconciler needed.
Read paths pipeline `ZCARD`/`SCARD` on the base key + `GET` on the
counter and sum. A missing counter is treated as 0, so pure non-CK
queues see the same answer as before.
The counter-aware scripts ship alongside the originals with a `Tracked`
suffix for rolling-deploy safety; a follow-up PR will drop the originals
once this has rolled out.
## Test plan
- [ ] `pnpm run test --filter @internal/run-engine` — 116 tests pass,
including a new `ckCounters.test.ts` covering lazy init from
pre-existing backlog, churn, floor-at-zero, the non-CK regression case,
mixed CK + non-CK on the same base queue, idempotent re-enqueue
(ZADD-already-exists), 24h TTL on the counter, and nack re-seeding after
counter expiry.
- [ ] Verified end-to-end against a live local environment:
- Triggered 24 CK enqueues across 4 variants → `lengthCounter=16`,
`runningCounter=8`, dashboard showed Queued=16 / Running=8 for the CK
queue.
- Set the env queue cap to 16, triggered 12 more enqueues → 8 succeeded,
4 rejected with `QueueSizeLimitExceededError`.
- Deleted the counter on a queue with 31 messages already sitting in CK
variants, triggered one more enqueue → counter materialized to 31 from
the `ckIndex` sum, then INCR'd.
## Summary
Consolidates the webapp's authentication and authorization into a small
set of route helpers, replacing the ad-hoc `requireUser` /
`requireUserId` / `authenticatedEnvironmentForAuthentication` calls
scattered across routes. Same security model, but the per-request flow
(authenticate → authorize → load) now lives in one place per route
family.
Introduces a plugin seam (`@trigger.dev/plugins`) that lets the cloud
build install a richer RBAC implementation without touching webapp code.
The OSS fallback keeps the pre-RBAC permissive behaviour intact, so
self-hosted deployments work unchanged.
Adds a comprehensive end-to-end auth test suite that didn't exist before
— 193 `it()` blocks (vitest reports ~199 after `it.each` expansion)
covering API key, PAT and JWT auth across the public API surface, plus
dashboard session auth for admin pages.
## Changes
### Plugin contract — `@trigger.dev/plugins`
`RoleBaseAccessController` interface authoritative for both OSS
(fallback) and cloud (enterprise plugin):
- `authenticateBearer(request, { allowJWT? })` — API-key / public-JWT
auth, returns env + ability
- `authenticateSession(request, { userId, organizationId?, projectId?
})` — dashboard auth, caller resolves `userId` from the session cookie
and passes it in (no `helpers.getSessionUserId` callback — decouples the
plugin host from session-cookie code)
- `authenticatePat(request, { organizationId?, projectId? })` — PAT
auth, returns identity + `lastAccessedAt` so the host can throttle the
per-request update
- `authenticateAuthorize*` variants for the auth-and-check-in-one-call
cases
- `isUsingPlugin(): Promise<boolean>` — capability flag for UI /
branching where plugin-present-ness matters; replaces the
sentinel-string coupling that had `personalAccessToken.server` matching
`"RBAC plugin not installed"` literally
### Dashboard auth (started, partial rollout)
Admin and settings pages migrated to a unified `dashboardLoader` /
`dashboardAction` helper that authenticates the session, runs an
authorization check, and exposes the result to the route. Other
dashboard routes still on the old pattern; remaining migration tracked
in TRI-8730.
Migrated routes:
- `admin.*` (14 admin / back-office / feature-flags / LLM-models /
notifications / orgs / concurrency pages)
- `_app.orgs.$organizationSlug.settings.team`
- `_app.orgs.$organizationSlug.settings.roles`
### API / realtime / engine auth (complete for the migrated families)
71 routes migrated to a unified `apiBuilder` that centralizes Bearer /
PAT / Public-JWT authentication and applies the per-route authorization
check before the handler runs. Includes:
- `api.v1.*` and `api.v2.*` and `api.v3.*` — tasks, runs, batches,
queues, prompts, deployments, query, sessions, waitpoints, packets,
workers, idempotency keys
- `realtime.v1.*` — runs, batches, sessions, streams
- `engine.v1.*` — dev / worker-action protocols
29 routes still on the legacy `authenticateApiRequest*` helpers —
tracked as a post-deploy follow-up in TRI-9228.
Multi-resource auth direction is now explicit at the call site via
`anyResource(...)` (OR) and `everyResource(...)` (AND). Bare arrays no
longer typecheck — fixes a class of bug where a JWT scoped to one
resource could implicitly access others under OR semantics.
PAT auth path consolidated: was three DB queries per request (legacy
`authenticateApiRequestWithPersonalAccessToken` findFirst +
`rbac.authenticatePat` join + `lastAccessedAt` update). Now one query in
the steady state — plugin returns `lastAccessedAt`, host smart-skips the
update via JS-side throttle when fresh.
Side effect: action aliases preserved historic JWT scope semantics where
the new model is stricter (e.g. a `write:tasks` JWT now also satisfies
`trigger` / `batchTrigger` / `update` actions on the same resource —
matched at the auth boundary, not in the route handler).
### Backwards-compat fixes
The strict-match model regressed several real-world JWT shapes. Each
preserved via explicit `anyResource(...)` entries in the route's authz
block:
- **Batch retrieve routes** (`api.v1.batches.$batchId`, `api.v2.*`,
`realtime.v1.batches.*`) accept `read:runs` JWTs again (pre-RBAC
literal-match superScope behaviour)
- **Runs list routes** (`api.v1.runs`, `realtime.v1.runs`) accept
type-level `read:tasks` / `read:tags` on unfiltered queries (matched the
legacy `Object.keys` iteration semantic)
- **PAT/OAT auth shape** normalized through `toAuthenticated` so all
auth methods return the same slim `AuthenticatedEnvironment` (was:
API-key returned the slim shape but PAT/OAT returned raw Prisma
`Decimal` / no `orgMember`)
- **Scope `:` preservation** in resource ids — `read:tags:env:staging`
now correctly identifies the tag id as `env:staging`, not `env`
### Slim `AuthenticatedEnvironment`
Extracted to `@trigger.dev/core/v3/auth/environment` — a structural
shape independent of `@trigger.dev/database`. The plugin contract
returns this; webapp consumers import from there; the cloud plugin
(Drizzle) returns the same shape without Prisma's `Decimal` class
leaking into the public surface. Lets internal-packages (run-engine,
etc.) refer to `AuthenticatedEnvironment` without pulling Prisma in.
### Auth test suite (new — `*.e2e.full.test.ts`)
193 e2e tests run against a real spawned webapp + Postgres (no mocks).
Coverage matrix:
- **API key auth** — read / write / trigger / batchTrigger / deploy
actions across runs, batches, deployments, prompts, queues, query,
sessions, input-streams, waitpoints, tasks, idempotency keys; multi-key
resources (a run carries batch / tag / task identifiers — auth must
accept any matching scope)
- **Personal Access Token auth** — comprehensive matrix: scope match,
scope mismatch, missing scope, expired token, malformed token
- **Public JWT auth** — sub-vs-URL environment resolution, expired JWTs,
signature verification, scope checking, otu (one-time-use) token
semantics, branch-environment signing-key fallback
- **Dashboard session auth** — admin-only pages reject non-admins;
per-action gating
- **Cross-cutting edge cases** — revoked API key grace window, JWT
cross-environment isolation, MissingResource branch behaviour
### Hygiene cleanups
- Deleted dead `app/services/authorization.server.ts` (legacy
`checkAuthorization` + types — no live consumers post-migration) and its
orphaned test
- Dropped the never-populated `scopes` field from
`ApiAuthenticationResultSuccess`
- `scheduleEmail` moved out of `email.server.ts` into its own module —
breaks a `commonWorker → marqs/V1` import chain that was poisoning the
auth test graph
- OSS Roles page shows a deployment-aware empty state ("Roles aren't
available in this self-hosted deployment" vs the plan-upsell copy) via
`rbac.isUsingPlugin()`
- Team action handler: explicit per-intent ability gates
(`manage:billing` for purchase-seats, `manage:members` for set-role +
remove-member with self-leave carve-out)
### Cross-repo coordination
All public-package contract changes paired in `triggerdotdev/cloud#763`
(rbac-packages branch) — the enterprise plugin implements the same
`RoleBaseAccessController` interface against Drizzle.
## Test plan
- [x] `pnpm run typecheck --filter webapp` clean
- [x] `pnpm --filter webapp exec vitest run --config
vitest.e2e.full.config.ts` — 193/193 pass (requires Docker for
testcontainers)
- [x] Spot-check an authed API endpoint with a valid + invalid API key
against a local stack
- [x] Spot-check the migrated admin pages render and gate non-admins

## Summary
Adds `.claude/REVIEW.md` — a repo-specific source of truth for what AI /
agent code reviewers should treat as critical in this codebase
(rolling-deploy safety, hot-table indexes, recovery-path queries,
testcontainers usage, etc.). Pairs with a Claude-based PR audit that
flags drift between REVIEW.md and the code as it evolves.
## How the audit works
Mirrors the existing `.github/workflows/claude-md-audit.yml` pattern. On
non-draft, non-fork PRs that touch code, `anthropics/claude-code-action`
reads REVIEW.md, samples the PR diff, and posts a sticky comment with up
to 3 of:
- `[stale]` — rule cites a path / function / table that's been removed
or renamed
- `[contradiction]` — code in the PR violates a current rule
- `[missing]` — PR introduces a new pattern future reviewers should know
about
- `[obsolete]` — rule asserts a constraint the repo has moved past
If nothing's off, posts `✅ REVIEW.md looks current for this PR.`
## Test plan
- [ ] Convert this PR to ready-for-review, confirm the audit runs and
posts a sticky comment
- [ ] Verify the audit doesn't run on fork PRs (gated by
`head.repo.full_name == github.repository`)
- [ ] Verify suggestions are actionable on at least one follow-up PR
Closes
[TRI-9234](https://linear.app/triggerdotdev/issue/TRI-9234/retry-task-process-sigsegv-errors-respecting-user-retry-config)
## What this changes
SIGSEGV crashes (`TASK_PROCESS_SIGSEGV`) will now be **retried when an
attempt fails**, in line with the task's configured retry settings
(`retry.maxAttempts` etc.) — the same path SIGTERM and uncaught
exceptions already use. Previously SIGSEGV was hard-classified as
non-retriable and failed the run on the first segfault, ignoring the
user's retry policy.
Tasks without a retry policy still fail fast on the first SIGSEGV.
Behaviour is unchanged for OOM kills (separate machine-bump retry path)
and SIGKILL_TIMEOUT.
## Deploy
**Only the webapp needs to ship.** The retry decision lives entirely in
the webapp:
- V2 path: `internal-packages/run-engine` (bundled into the webapp)
- V1 path: `apps/webapp/app/v3/services/completeAttempt.server.ts`
No supervisor, CLI, SDK, or customer-task-image changes required.
Customers do not need to redeploy. The `@trigger.dev/core` changeset is
just keeping the public package in sync — the published npm version
isn't what makes the fix work.
## Why retry
SIGSEGV in Node tasks is frequently non-deterministic across processes:
- **Native addon races** (`sharp`, `canvas`, `better-sqlite3`,
`node-rdkafka`, `bcrypt`, …) — libuv thread-pool work stepping on V8
handles. Different heap layout / thread schedule on a fresh process →
retry often succeeds.
- **JIT / GC interaction** — V8 turbofan deopt or GC during a native
callback. Timing-dependent.
- **Near-OOM in native code** — when RSS approaches the cgroup limit,
native allocations fail and poorly-written addons dereference NULL →
SIGSEGV instead of clean OOM-kill.
- **Host / hardware issues** — bit flips, kernel quirks. Retry lands on
a different host.
The genuinely deterministic case (a user-code bug always tripping the
same addon) is real, but a subset — and `maxAttempts` bounds the damage.
## Pre-existing inconsistency this resolves
- `shouldRetryError` returned `false` for `TASK_PROCESS_SIGSEGV` →
`fail_run`.
- `shouldLookupRetrySettings` already listed `TASK_PROCESS_SIGSEGV` as
retry-config-aware — but that branch was unreachable because
`shouldRetryError` short-circuited first in `retrying.ts:86-90`.
- We already retry `TASK_RUN_UNCAUGHT_EXCEPTION` (clearly a user-code
bug) under the user's retry policy; refusing to retry SIGSEGV was the
odd one out.

## Summary
1 improvement, 1 bug fix.
## Improvements
- Fail attempts on uncaught exceptions instead of hanging to
`MAX_DURATION_EXCEEDED`. A Node `EventEmitter` (e.g. `node-redis`)
emitting `"error"` with no `.on("error", ...)` listener escalates to
`uncaughtException`, which the worker previously reported but did not
act on — runs drifted to maxDuration with empty attempts. They now fail
fast with the original error and status `FAILED`, and respect the task's
normal retry policy. You should still attach `.on("error", ...)`
listeners to long-lived clients to handle errors gracefully.
([#3529](https://github.com/triggerdotdev/trigger.dev/pull/3529))
## Bug fixes
- Fix dev workers spinning at 100% CPU after the parent CLI disconnects.
Orphaned `trigger-dev-run-worker` (and indexer) processes were caught in
an `uncaughtException` feedback loop: a periodic IPC send via
`process.send` would throw `ERR_IPC_CHANNEL_CLOSED` once the parent
closed the channel, which re-entered the same handler that itself called
`process.send`, scheduled via `setImmediate` and amplified by
source-map-support's `prepareStackTrace`. Fixed by (1) silently dropping
packets in `ZodIpcConnection` when the channel is disconnected, (2)
adding a `process.on("disconnect", ...)` handler in dev workers so they
exit cleanly when the CLI closes the IPC channel, and (3) wrapping all
`uncaughtException`-path `process.send` calls in a `safeSend` guard that
checks `process.connected` and swallows synchronous throws.

## Summary
Make `taskIdentifier` optional on the run-queue message schema. No
behavior change in this PR; readers continue to accept payloads that
include the field. A separate change will stop writing it on the wire to
shrink the per-run payload that lives in Redis while runs wait to be
dequeued.
## Design
The field is written into every payload at enqueue time but no consumer
reads it back on the dequeue path. Both the run-engine and supervisor
derive `taskIdentifier` from the loaded `TaskRun` row instead. Relaxing
the schema first means readers tolerate payloads that omit it, so the
writer-side change can ship without producing schema-parse errors during
a rolling deploy.
`projectId` is left required: `WorkerQueueResolver.#getOverride` reads
it for project-scoped runtime worker-queue overrides.
## Test plan
- [x] `pnpm run typecheck --filter @internal/run-engine`
- [x] `pnpm run typecheck --filter webapp`
- [x] `pnpm run test ./src/run-queue/tests/enqueueMessage.test.ts
./src/run-queue/tests/workerQueueResolver.test.ts --run` (28/28 passing)
## Summary
TTL expiration on queued runs was being scheduled twice: once via a
per-run `expireRun` worker job (the original implementation) and once
via the batch TTL system (added more recently). Both paths attempt to
flip the same run to `EXPIRED`. The per-run job almost always won the
race, leaving the batch consumer to observe runs already expired by the
older path.
This collapses TTL expiration onto the batch path so every queued TTLed
run goes through a single Redis-backed sorted set + batch consumer
instead of also getting its own scheduled redis-worker job.
## Design
`engine.trigger` and `delayedRunSystem.enqueueDelayedRun` no longer call
`ttlSystem.scheduleExpireRun`. The remaining `enqueueSystem.enqueueRun({
includeTtl: true })` already adds the run to the TTL sorted set;
`TtlSystem.expireRunsBatch` flips it to `EXPIRED` when the TTL fires.
Delayed runs get the same coverage by passing `includeTtl: true` on
their post-delay enqueue, so the TTL is armed from the moment the run
enters the queue (matching how the old job behaved —
`parseNaturalLanguageDuration` is evaluated at enqueue time).
The new path explicitly does not re-expire runs once they have been
allocated a concurrency slot. That is intentional: TTL is for runs that
are queued and have never started. Once a run has a slot it is on its
way to executing.
## Test plan
- [x] `pnpm run test --filter @internal/run-engine
./src/engine/tests/ttl.test.ts` — 15 tests, including a new "Re-enqueued
runs are not expired by TTL once they have started" that locks in the
queued-and-never-started contract.
- [x] `pnpm run test --filter @internal/run-engine
./src/engine/tests/delays.test.ts` — 5 tests, including "Delayed run
with a ttl" which now also asserts the TTL is armed from queue-enter
time, not `createdAt`.
- [x] `pnpm run test --filter @internal/run-engine
./src/engine/tests/lazyWaitpoint.test.ts` — 12 tests.
- [x] `pnpm run typecheck --filter @internal/run-engine`.
## Summary
- Adds admin-only editors on the back-office org page for
`Organization.maximumProjectCount` and
`Organization.batchRateLimitConfig`, alongside the existing API rate
limit editor.
- Splits the back-office org page into per-section components
(`ApiRateLimitSection`, `BatchRateLimitSection`, `MaxProjectsSection`)
so each tool is self-contained — adding new sections later doesn't bloat
the route.
- Generalizes the rate-limit form into a reusable `RateLimitSection`
component + `RateLimitDomain` server config so API and batch share the
same UI, validation, and action handler. Each domain only owns its env
defaults, DB column, and logger key.
- "Saved." banner and validation errors are scoped to the section that
submitted, not the page.
Heads-up: the API rate-limit log key was renamed
`admin.backOffice.rateLimit` → `admin.backOffice.apiRateLimit` for
symmetry with the new `admin.backOffice.batchRateLimit`.
## Test plan
- [ ] As an admin, visit `/admin/back-office/orgs/:orgId` and confirm
all three sections render with the org's current values (or system
defaults).
- [ ] Edit and save each section; confirm only that section shows the
"Saved." banner.
- [ ] Submit invalid input (e.g. `0` tokens, malformed interval);
confirm errors render in the offending form only and the other sections
stay closed.
- [ ] Confirm a non-admin user is redirected away from the route.
- [ ] After saving a rate-limit override, hit the org with traffic and
confirm the new limit is enforced (API rate limit + batch rate limit
code paths read the column at request time).
## Summary
When ElastiCache demotes a primary to replica — during a Multi-AZ
failover or a vertical node-type change — the demoting primary issues an
`UNBLOCKED` reply to any in-flight blocking commands (`BLPOP`, `BRPOP`,
`BLMOVE`, `XREADGROUP ... BLOCK`, etc.) to clear them before the role
flips. ioredis surfaces these as `ReplyError` to caller code.
The shared `defaultReconnectOnError` added in #3548 only matches
`READONLY` and `LOADING`. This extends it to `UNBLOCKED` so the
disconnect-reconnect-retry cycle handles BLPOP-shaped errors the same
way the existing two cases handle non-blocking-command errors.
## Fix
```ts
export function defaultReconnectOnError(err: Error): boolean | 1 | 2 {
const msg = err.message ?? "";
if (
msg.startsWith("READONLY") ||
msg.startsWith("LOADING") ||
msg.startsWith("UNBLOCKED")
) {
return 2;
}
return false;
}
```
Returning `2` tells ioredis to disconnect, reconnect, and re-issue the
command. For a BLPOP that means a fresh BLPOP against the new primary
instead of the `UNBLOCKED` error escaping to the caller.
## Test plan
- [ ] CI green
- [ ] Trigger a Multi-AZ failover or a vertical scale event on an
ElastiCache replication group whose clients are running blocking
commands and confirm no `UNBLOCKED` errors surface to caller code during
the cutover.
## Summary
During an ElastiCache role swap (failover) or node-type change (vertical
scale), the ioredis TCP/TLS connection stays open but the server starts
answering with `READONLY` (the client is talking to a node that became a
replica) or `LOADING` (node still loading data from disk). Without an
explicit hook, those errors surface to caller code as `ReplyError`
instances — every write op on the affected connection fails until the
cluster fully cuts over.
This PR adds `reconnectOnError` to every prod ioredis client so the
disconnect + reconnect + retry cycle absorbs these errors and caller
code never sees them.
## Fix
```ts
export function defaultReconnectOnError(err: Error): boolean | 1 | 2 {
const msg = err.message ?? "";
if (msg.startsWith("READONLY") || msg.startsWith("LOADING")) return 2;
return false;
}
```
Returning `2` tells ioredis to disconnect, reconnect, and re-issue the
failed command. After reconnect, DNS / SG state routes the new socket to
a writable node.
The helper lives in `@internal/redis` and is wired into both the shared
`createRedisClient` (which covers RunQueue, schedule-engine,
redis-worker, and every other internal-package consumer) and the direct
`new Redis(...)` call sites in the webapp.
V1-only marqs files are intentionally not migrated.
## Test plan
- [x] `pnpm run typecheck --filter webapp`
- [x] `pnpm run typecheck --filter @internal/run-engine`
- [x] Verified end-to-end against a live ElastiCache vertical-scale
event — caller-surfaced errors went from tens of thousands during the
cutover window down to a handful per ioredis client
- [ ] Confirm steady-state behavior unchanged after deploy
## Summary
- Run-view inspector panel was glitching out on Firefox: visual flicker
on close, locking up at min size, and intermittent `panelHasSpace`
invariant errors. Root cause is the underlying `react-window-splitter`
library's collapse animation, which uses `@react-spring/rafz` and
interacts poorly with Firefox.
- Disabled the library's collapse animation on Firefox only, app-wide
(every consumer of `RESIZABLE_PANEL_ANIMATION`). Chromium and Safari
behaviour is unchanged.
## Changes
- **Firefox animation skip** in `RESIZABLE_PANEL_ANIMATION` —
UA-detected at module load, resolves to `undefined` for Firefox so the
library's animation actor completes in one frame instead of running its
rAF loop.
- **Inspector min raised 50px → 250px** so dragging can't shrink the
panel into a near-useless width.
- **`autosaveId` bumped `v2` → `v3`** to invalidate stale persisted
snapshots (the library has a `// TODO` branch that ignores prop changes
for already-registered panels, so existing users would otherwise still
see the old 50px min).
- **`react-window-splitter` pinned** to exact `0.4.1` to protect the
patch from drifting if line offsets change in a patch release.
- **Two hunks added to the existing `@window-splitter/state` patch:**
- Removed the library's auto-collapse-on-drag block entirely. Every
collapsible panel in the app is parent-controlled, and that block was
triggering state-machine deadlocks when handlers were no-ops.
Drag-to-collapse is now disabled across the app; collapse is only
triggered explicitly (close button, ESC, URL change, etc.).
- In `getDeltaForEvent`, fall back to the panel's `default` before its
`min` when expanding — so the first ever click on a span opens the
inspector at 500px, not 250px.
## Local testing confirmed
- [x] Firefox: open a run, click various spans → panel opens instantly
at 500px, drags freely between 250px and max, closes instantly to 0. No
console errors.
- [x] Chrome/Chromium: same flow, but with smooth open/close animation
as before.
- [x] Safari: same as Chrome.
- [x] Reload mid-session → panel restores cleanly to the dragged size.
- [x] Other resizable panels in the app (logs, deployments, schedules,
batches, bulk-actions, runs index) still animate on Chromium/Safari.
## Notes
- Linear: TRI-8584
- Branch contains intermediate commits exploring an unsuccessful
snapshot-validator approach; they're reverted by the final commit.
Cumulative diff is 6 files. Squash on merge if you'd prefer a clean
history.

## Summary
Adds a Redis pub/sub reload path to the webapp's in-memory LLM pricing
registry. When enabled on a process, the registry reloads from the
database whenever a publish lands on the configured channel — instead of
waiting for the existing 5-minute interval. Lets pricing/model changes
propagate to cost enrichment within seconds.
Subscription is **off by default** and opt-in per process. Only
OTel-ingesting services need real-time freshness; dashboard and worker
services run fine on the periodic interval and shouldn't pile onto each
publish with a full-table reload.
## Design
When `LLM_PRICING_RELOAD_PUBSUB_ENABLED=true`, subscribes via
`createRedisClient` against `COMMON_WORKER_REDIS_*` and listens on
`LLM_PRICING_RELOAD_CHANNEL` (default `llm-registry:reload`). The
5-minute periodic reload stays as a backstop, and a SIGTERM/SIGINT
handler closes the subscription cleanly.
The publisher side lives outside this PR — any process running in the
same Redis namespace can trigger a reload by `PUBLISH
llm-registry:reload <anything>`. Includes a `.server-changes/` note for
the changelog.
### Debounced reload
Bursts of publishes are coalesced. The first publish schedules a reload
at T+`LLM_PRICING_RELOAD_DEBOUNCE_MS` (default 1s); subsequent publishes
during that window are no-ops because the trailing reload picks up
everything when it queries the DB. Bounds reload rate to at most 1 per
debounce window regardless of publisher chattiness, so a runaway
upstream publisher can't fan out into a flood of full-table-scan
reloads.
## Test plan
- [ ] With `LLM_PRICING_RELOAD_PUBSUB_ENABLED=false` (default):
`redis-cli PUBSUB NUMSUB llm-registry:reload` returns `0` while the
webapp is up
- [ ] With it set to `true`: returns `>= 1`
- [ ] `redis-cli PUBLISH llm-registry:reload test` returns `1` (one
subscriber received) on a subscribed process
- [ ] Mutate an `LlmModel` row externally, publish on the channel,
observe the registry's match() picks up the change without waiting for
the 5-min tick
- [ ] Publish 100x in rapid succession; confirm only one reload fires
within the debounce window
When a webapp API route's catch-all 500 branch handles a non-typed
exception, it returns the raw `error.message` to the caller. If the
exception originates from an internal subsystem (the ORM client, an
infra dependency, etc.) the server-side error string is surfaced
verbatim in the response body — exposing implementation details the API
surface shouldn't carry.
The leak shows up in three shapes across the routes:
- `return json({ error: error.message }, { status: 500 })`
- `return json({ error: error instanceof Error ? error.message :
"Internal Server Error" }, { status: 500 })`
- ``return json({ error: `Internal server error: ${error.message}` }, {
status: 500 })``
(plus a couple of analogous neverthrow-Result variants on admin routes.)
## Fix
Across 19 webapp routes, replace each leaking branch with a generic body
(`"Something went wrong"` / `"Internal Server Error"` to match the
file's existing fallback) and add `logger.error(...)` so full visibility
is preserved server-side. Catch blocks that branch on typed user-input
errors (`ServiceValidationError`, `EngineServiceValidationError`,
`OutOfEntitlementError`, `PrismaClientKnownRequestError`) are left
intact — those messages are constructed deliberately and intended to be
customer-facing.
## Test plan
- [x] `pnpm run typecheck --filter webapp`
- [x] Per-route manual probe: inject a synthetic `Error` at the top of
the catch'd `try` block (or fake the wrapped call's rejection / Result
error), curl the route with the dev API key, confirm the response body
changed from the synthetic message verbatim → generic body. 21/21 leak
sites verified end-to-end.
- [x] 4xx-typed-error paths spot-checked: throwing
`ServiceValidationError` from inside the catch'd try still surfaces its
message at 422 as intended.
## Summary
Stamps the active OpenTelemetry `trace_id` and `span_id` onto every
Sentry event captured from the webapp, so engineers can copy a
`trace_id` from a Sentry issue and search for the corresponding trace in
any OTel-aware backend. Also adds an `otel_sampled` tag to indicate
whether the trace was head-sampled — a cheap signal for whether the link
will resolve to span data or hit a missing trace.
## Why
Sentry and OTel were OTel-disconnected: `apps/webapp/sentry.server.ts`
initialised Sentry with `skipOpenTelemetrySetup: true`, and no
error-capture site (`logger.server.ts`, the Remix-wrapped `handleError`,
the root `ErrorBoundary`) attached OTel context to the event. With many
spans/sec across services, getting from a Sentry issue to its trace was
guesswork.
## Approach
Single global Sentry event processor, registered immediately after
`Sentry.init`. On each event it reads
`trace.getActiveSpan()?.spanContext()` via `@opentelemetry/api`, then
writes:
- `event.contexts.trace.trace_id` and `event.contexts.trace.span_id`
(Sentry's native trace context fields)
- `event.tags.otel_sampled` = `"true"` | `"false"` (derived from
`traceFlags`)
If no active span (module-load errors, scheduled timers without a
context, primary cluster process), the processor returns the event
unmodified — Sentry's default propagation context fills in.
Implementation is co-located in `apps/webapp/sentry.server.ts` (no
separate helper module — `sentry.server.ts` is built standalone by
esbuild and a separate import would have required a new bundling step).
Helper functions are exported so the unit tests can reach them without
re-running `Sentry.init`.
## Non-goals (deliberate)
- No sample rate change. ~95% of Sentry events will carry a `trace_id`
that returns no spans in the tracing backend (head-sampled out). The
`otel_sampled` tag makes that obvious at a glance. Raising find-rate is
a separate conversation with cost trade-offs.
- No user/org tags or `Sentry.setUser` (would need auth-helper +
per-request scope wiring across multiple worker entrypoints — separate
ticket).
- Webapp image only. No changes to supervisor or CLI workers.
## Test plan
- [x] Unit tests in `apps/webapp/test/sentryTraceContext.server.test.ts`
— 9 tests covering: helper returns \`undefined\` with no active span;
returns \`traceId\`/\`spanId\`/\`sampled=true\` for a recording span;
returns \`sampled=false\` for a non-recording span; processor leaves the
event unchanged with no active span; processor stamps
\`trace_id\`/\`span_id\` onto \`contexts.trace\`; preserves existing
\`contexts.trace\` fields; tags \`otel_sampled\` correctly for both
sampled and non-sampled cases; never throws if \`@opentelemetry/api\`
access throws.
- [x] \`pnpm run typecheck --filter webapp\` passes.
- [x] Manually verified end-to-end against a sandboxed Sentry project:
confirmed both sampled and non-sampled traces correctly populate
\`contexts.trace.trace_id\` matching the OTel ids logged from the
loader, and the \`otel_sampled\` tag appears with the expected value.

## Summary
Both Claude Code workflows (`claude.yml` and `claude-md-audit.yml`)
authenticated via `CLAUDE_CODE_OAUTH_TOKEN`, which broke when the org
disabled Claude subscription access for Claude Code:
> Your organization has disabled Claude subscription access for Claude
Code · Use an Anthropic API key instead, or ask your admin to enable
access
This switches both workflows to `anthropic_api_key: ${{
secrets.ANTHROPIC_API_KEY }}` (secret already added to the repo).
## Test plan
- [ ] Confirm `📝 CLAUDE.md Audit` runs to completion on this PR
- [ ] Confirm `@claude` mention in a PR comment still triggers the
`Claude Code` workflow successfully
When a Node EventEmitter (e.g. node-redis) emits an "error" event with
no
listener attached, Node escalates it to process.on("uncaughtException")
in
the task worker. The worker reported the error via the
UNCAUGHT_EXCEPTION
IPC event but did not exit, and the supervisor-side handler in
taskRunProcess only logged the message at debug level — leaving the
run()
promise orphaned until maxDuration fired and producing empty attempts
(durationMs=0, costInCents=0).
The supervisor now rejects the in-flight attempt with an
UncaughtExceptionError and gracefully terminates the worker (preserving
the OTEL flush window) on UNCAUGHT_EXCEPTION. The attempt fails fast
with
TASK_EXECUTION_FAILED, surfacing the original error name, message, and
stack trace, and falls under the normal retry policy. This mirrors the
existing indexing-side behavior in indexWorkerManifest. Apply the same
handling to unhandled promise rejections, which Node already routes
through uncaughtException by default.
- Tags webapp images by full commit SHA on `main` pushes
(`ghcr.io/triggerdotdev/trigger.dev:<sha>`) so any commit can be
resolved to a digest easily.
- Adds OCI labels (`source`, `revision`, `version`, `created`) so
`docker inspect`, vulnerability scanners, and
registry browsers see source/commit/version directly.
- Signs each pushed digest with SLSA build provenance via
`actions/attest-build-provenance@v4.1.0` (pinned by SHA), enabling `gh
attestation verify oci://...` against the source commit and workflow.
Large deploys (projects with many tasks or source files) blocked the
webapp event loop for several seconds inside Prisma's client-side
serializer on `BackgroundWorker.create`, tail-latencying every other
in-flight request on the same Node process. The `metadata` JSON column
was being written with the full deploy manifest — every task's config,
every queue and prompt, and the full source of every file — all of which
already live on dedicated columns or in dedicated tables.
Fix: project the manifest to `{ packageVersion, contentHash, tasks: [{
id, filePath, schedule }] }` on insert. The only post-write read site is
`changeCurrentDeployment`, which feeds `tasks[].schedule` into
`syncDeclarativeSchedules` at deploy promotion. The retained top-level
keys and per-task `filePath` are kept solely so
`BackgroundWorkerMetadata.safeParse` still succeeds on read.
## Test plan
- [ ] Deploy a project with declarative schedules; verify schedules are
created on first deploy
- [ ] Modify / remove schedules across subsequent deploys; verify sync
- [ ] Roll back to a previous deploy; verify `changeCurrentDeployment`
re-syncs schedules
- [ ] Inspect `BackgroundWorker.metadata` on a fresh deploy — should be
a small object, not the full manifest
`dac9c83bd` added `ignoreErrors: /^ServiceValidationError(?::|$)/` in
`apps/webapp/sentry.server.ts` to drop SVEs before they reach Sentry.
The
filter only matches when the captured event's *type* is
`ServiceValidationError`, but nine call sites in the webapp catch SVE
(and
analogous user-input error types — `OutOfEntitlementError`,
`CreateDeclarativeScheduleError`, `QueryError`) and call
`logger.error("wrapper message", { error: e })` *before* the type check.
The captured event is then titled with the wrapper message, with the
inner
error buried in `extra.error` — invisible to the SDK filter. Result: a
steady stream of expected user-input failures escalating as
`error`-level
events when they should be `warn`.
Each catch block now type-discriminates first, logs expected types at
`warn`,
and keeps unknown-error fall-throughs at `error`. For service sites that
wrap into SVE (`createBackgroundWorker`,
`createDeploymentBackgroundWorkerV4`),
the inner error is logged at `error` before wrapping — mirrors the
`waitpointCompletionPacket.server.ts` pattern from `dac9c83bd`.

Fixes#3520. The bundled bitnami clickhouse subchart was pinned at
`9.3.7` (clickhouse `25.6.1-debian-12-r0`), which hits a memory-tracker
accounting bug under sustained ingest - the global counter overflows to
~7 EiB and every query gets rejected by OvercommitTracker until the pod
is restarted. Self-hosters running 4.0.5 through 4.4.5 are exposed
regardless of chart version since the subchart pin hadn't moved.
Bumping to `9.4.4` (clickhouse `25.7.5-debian-12-r0`) pulls in the
25.7.x memory-tracker fixes. This is also the latest publicly packaged
release at `oci://registry-1.docker.io/bitnamicharts` - that registry
has been frozen since 2025-08-28 (Bitnami catalog changes), but the
chart source remains under Apache 2 on `bitnami/charts`. The image
continues to resolve via `bitnamilegacy/clickhouse` per the existing
`values.yaml` override, since `bitnami/clickhouse` itself moved to
paid-only.
Verified locally: `helm dependency update` + `helm lint` + `helm
template` + kubeconform across all 57 rendered manifests. Rendered
statefulset image is
`docker.io/bitnamilegacy/clickhouse:25.7.5-debian-12-r0`.
## Summary
Move from a single shared S2 basin to **per-org basins** with retention
tied to the org's billing plan. Stops S2 from deleting streams out from
under live chat sessions when basin retention fires before the chat
ends, and unlocks per-org cost attribution.
OSS / s2-lite installs are unaffected: provisioning is gated by
`REALTIME_STREAMS_PER_ORG_BASINS_ENABLED` (default `false`), and the
read precedence falls back to the global basin env var when an entity
has no stamped basin.
```
basin = run.streamBasinName ?? session.streamBasinName ?? env.REALTIME_STREAMS_S2_BASIN
```
## Design
Three nullable `streamBasinName` columns (`Organization`, `TaskRun`,
`Session`) plus a provisioner that idempotently creates the basin and
reconfigures retention on plan changes. The trigger and session-create
paths stamp the org's basin onto new rows; the realtime read path picks
the basin from the entity context.
Admin routes back-fill existing orgs and force-reconfigure a single org.
## Test plan
- [x] `pnpm run typecheck --filter webapp --filter @internal/run-engine`
- [x] Backfill admin route end-to-end (provision + DB stamp + S2 basin
config).
- [x] Reconfigure on plan change (all retention tiers).
- [x] chat.agent multi-turn drives streams into the per-org basin.
- [x] Legacy fallback when entity has no stamped basin.
- [x] Provisioner is a no-op when the flag is off.
Adds zizmor alongside the actionlint job from #3503. Both now run as
parallel jobs in a single `.github/workflows/workflow-checks.yml`,
triggered on `.github/workflows/**` and `.github/actions/**` changes.
Zizmor is configured with `unpinned-uses: hash-pin` policy via
`.github/zizmor.yml`, so any future unpinned action will fail CI.
Findings upload SARIF to the Security tab alongside CodeQL.
Bulk of the diff is cleanup of the findings zizmor surfaced on first
run. `zizmor --fix=all` handled most of them mechanically; the rest were
judgment calls.

## Performance
- **Per-request DB hit**: `getUserId` runs `getEffectiveSessionDuration`
(User lookup + Org `aggregate`) on *every* authenticated request,
including each fetcher poll. Consider caching the effective duration in
the session cookie with a short TTL (e.g. 60s) and revalidating in the
background.
- **Double session commit in `root.tsx`**: `getUser` already runs the
expiry check; then `commitAuthenticatedSessionLazy` commits the cookie
again. Fine, but doubles `Set-Cookie` headers on every page load — worth
a quick perf check.
## Correctness / Edge cases
- **Lazy backfill assumes a root.tsx hit first**: users whose first
post-deploy request is a fetcher/API route (`/resources/*`) skip the
backfill until they navigate to a page. Not a security hole, but
`getUserId` could backfill itself for completeness.
- **No upper bound on `Organization.maxSessionDuration`**: admin API
accepts `1` second, which would instant-logout every member on next
request. Add a `min(60)` (or `min(300)` to match the lowest user option)
to the Zod schema.
- **No clock-skew tolerance**: `isSessionExpired` is exact-millisecond.
Multi-instance deploys with skewed clocks could log users out a few
seconds early/late. Probably fine for the 5-min minimum, but worth
noting.
## Security
- **Auto-logout audit log lacks IP/orgId**: HIPAA forensics typically
wants source IP and which org context. Currently logs only `userId` +
path. IP isn't PII for audit purposes; orgIds help correlate. Add both.
- **Cookie `Max-Age` is 1 year regardless of user's setting**:
intentional (server-side `issuedAt` is the source of truth), but
reviewers will ask. Add a one-line comment on the cookie config
explaining why.
## API surface
- **`maxSessionDuration` is admin-PAT only**: no in-app UI for org
owners to set/change their own cap. If this is "Trigger staff sets it
during HIPAA onboarding", say so in the PR description; otherwise add an
org-settings UI.
- **Auto-submit dropdown has no confirmation**: misclicking "5 minutes"
immediately shortens the user's session window with no undo. Consider a
save button or 3-sec undo toast.
## Schema / migration
- **`User.sessionDuration NOT NULL DEFAULT 31556952`**: instant on PG
11+ (metadata-only), but call out in the PR description so reviewers
don't worry about a table rewrite on the User table.
- **No DB-level constraint matching `SESSION_DURATION_OPTIONS`**: if the
option list changes, existing users keep orphaned values. The dropdown's
tag-along behaviour hides this — fine for now, but if you ever drop an
option you'll need a backfill.
## UX
- **Session expiry only fires on next request**: an idle authenticated
tab keeps showing UI past the cap (until SSE/polling catches it, ~60s).
Add a client-side timer based on the user's effective duration that
triggers a fetcher to `/account` or `/logout` at expiry.
- **No "you were signed out" message on logout**: users hitting their
cap are bounced to `/` with no explanation. Was intentionally reverted
in this PR — call that out so reviewers don't request it.
## Tests
- Unit coverage on `sessionDuration.server.ts` is solid (215 lines).
Missing: integration test for `getUserId` → expired session → redirect
to `/logout`, and one for the loader's clamping fix (the most recent
bug). Add at least the second one to lock in the regression.

Reported by external contributor. The supervisor template hardcoded a
short DNS name for `OTEL_EXPORTER_OTLP_ENDPOINT`, which the supervisor
then propagates verbatim into runner pods
(`apps/supervisor/src/workloadManager/kubernetes.ts:196`). When runners
are spawned in a different namespace via
`supervisor.config.kubernetes.namespace`, the short name doesn't resolve
and span/log export silently fails - runs complete fine but the
dashboard shows nothing.
Same FQDN pattern the chart already uses for
`TRIGGER_WORKLOAD_API_DOMAIN` (line 203). Verified with `helm template
trigger . --namespace my-ns` - renders
`http://trigger-webapp.my-ns.svc.cluster.local:3030/otel`.

## Summary
Delete 34 `.server-changes/*.md` files that should have been cleaned up
automatically when v4.4.5 (#3406) was merged but were stranded by a
workflow race.
## Why these are stale
The `update-lockfile` job in `.github/workflows/changesets-pr.yml` is
what cleans up consumed `.server-changes/*.md` files on the release
branch. When v4.4.5 was merged on 2026-05-01, the post-merge workflow
run on `main` failed at `pnpm install --frozen-lockfile` (stale lockfile
in the merge commit), and `cancel-in-progress: true` cancelled the
in-flight run from the previous push — so `update-lockfile` never
reached the cleanup step.
Result: the 34 files described changes that v4.4.5 already shipped, and
they were re-appearing in the v4.4.6 release PR (#3501) under "Server
changes" plus showing up as deletions in its diff.
## What this PR keeps
- `fix-rollback-schedule-sync.md` — genuinely new for v4.4.6 (#3468),
the only server change introduced after v4.4.5
- `README.md`, `.gitkeep` — directory infrastructure
- `dev-cli-disconnect-md` — leaving alone (typo'd filename from March,
no `.md` extension, not picked up by the cleanup glob anyway)
## After merge
The next run of `changesets-pr.yml` will refresh #3501 with a "Server
changes" section that only lists the v4.4.6 entry, and the only
`.server-changes/` deletion in its diff will be
`fix-rollback-schedule-sync.md`.
## Related
- #3505 is the proper underlying fix — collapses the three-job graph
into a single atomic commit by `changesets/action` so this race can't
strand the cleanup again. This PR is just the one-time catch-up for the
files that already got stranded.
Follow-up to the v4.4.5 release incident where the release PR (#3406)
was merged with a stale lockfile and stale Chart.yaml, breaking npm +
helm releases. The two automation jobs (`update-lockfile`,
`bump-chart-version`) got cancelled mid-flight by `cancel-in-progress`
when the merge fired the workflow again on `main`.
This restructures `changeset:version` so all the post-version-bump
fixups happen in the same script and end up in a single atomic commit on
`changeset-release/main`, via `changesets/action`'s normal commit step.
Pattern borrowed from Cloudflare workers-sdk, Astro, shadcn/ui.
## Before
```
push: main
└── release-pr (changeset version → bumps package.jsons, opens PR)
└── update-lockfile (separate job, separate commit)
└── bump-chart-version (separate job, separate commit)
```
Three jobs, three commits to the release branch.
## After
```
push: main
└── release-pr
└── changesets/action runs:
changeset version
pnpm install --lockfile-only
node scripts/bump-helm-chart.mjs
node scripts/cleanup-server-changes.mjs
...all staged and committed as ONE commit by the action
```
One job, one commit.
Adds an `actionlint` job that runs on changes to `.github/workflows/**`
and `.github/actions/**`. Catches workflow bugs at PR time — expression
typos, deprecated runner labels, broken matrices, and shellcheck issues
in `run:` blocks.
Run from the official `docker://rhysd/actionlint` image, digest-pinned
alongside everything else.
Existing workflows had 6 shellcheck findings, all fixed.
Updates the compute private beta page with the May 1 release entry, plus
a deploy-time warning when `us-east-1-next` is the project default.
The new What's new entry, verbatim:
### May 1, 2026
- **Cold starts are faster across all machine sizes.** Every preset
starts faster, including `micro` and `small-1x` - there's no longer a
cold-start penalty for picking a smaller machine.
- **First runs after a deploy are faster on every preset.** Boot
snapshot creation is significantly quicker across the board, so the cold
path is consistently snappier.
- **`large-1x` and `large-2x` no longer hard-fail.** They're still not
recommended - cold-start performance trails the smaller presets and
we're ironing out reliability issues.
Follow-up to #3472 and #3479.
Orphaned `trigger-dev-run-worker` processes were pinning CPU at 100%
after the dev CLI exited — stuck in an uncaughtException feedback loop
where a closed IPC channel kept throwing `ERR_IPC_CHANNEL_CLOSED` back
into a handler that itself called `process.send`.
Fix:
- `ZodIpcConnection` no-ops sends when the channel is disconnected.
- Dev workers exit on `process.disconnect` instead of being re-parented
to init.
- All worker `uncaughtException` handlers route through a `safeSend`
guard so the handler can never re-enter itself.
Verified end-to-end: `kill -9` of the dev CLI now cleans up all child
workers within ~2s.
Last action still firing the Node 20 deprecation warning after #3494.
`buildjet/setup-node@v4.0.4` (the latest tag) declares `runs: using:
'node20'` and the repo hasn't shipped a node24 update.
Workflows here run on `ubuntu-latest` (not buildjet runners), so the
buildjet fork wasn't giving us anything we don't get from
`actions/setup-node` directly. Swapping to `actions/setup-node@v6.4.0`
(node24 runtime) silences the warning.
## Summary
Each successful PAT (`PersonalAccessToken`) or OAT
(`OrganizationAccessToken`) authentication issues a `prisma.X.update({
lastAccessedAt: new Date() })` to bump the timestamp. For tokens used at
high frequency (CLI clients, integrations) this generates a per-request
DB write that is mostly redundant — the `lastAccessedAt` field is only
surfaced on the settings page so users can decide which tokens to
revoke, and "within the last 5 minutes" is plenty of granularity for
that.
## Design
Replace each unconditional `update` with a conditional `updateMany`
whose `WHERE` requires the existing `lastAccessedAt` to be `NULL` or
strictly older than 5 minutes:
```ts
await prisma.personalAccessToken.updateMany({
where: {
id: personalAccessToken.id,
OR: [
{ lastAccessedAt: null },
{ lastAccessedAt: { lt: new Date(Date.now() - PAT_LAST_ACCESSED_THROTTLE_MS) } },
],
},
data: { lastAccessedAt: new Date() },
});
```
The conditional runs inside the SQL `UPDATE`, so concurrent auths can't
race into a double-write.
No schema change. No migration. No new infrastructure. Throttle is a
hardcoded constant (`5 * 60 * 1000`) — easy to revisit.
## Test plan
- [x] `pnpm run typecheck --filter webapp`
- [x] `pnpm vitest run ./test/services/personalAccessToken.test.ts
./test/services/organizationAccessToken.test.ts` — 6/6 pass, verifying
the throttle `WHERE` clause is constructed correctly and the `update` is
skipped on token-not-found / wrong-prefix paths
Follow-up to v4.4.5 release. The `bump-chart-version` job on the release
PR was cancelled before it could run, so Chart.yaml was merged still
pointing at 4.4.4. The helm release job ([failed
run](https://github.com/triggerdotdev/trigger.dev/actions/runs/25218553990/job/73947054128))
caught it via its version-match guard.
Once this merges I'll re-run the helm release workflow manually.
## ✅ Checklist
- [x] I have followed every step in the [contributing
guide](https://github.com/triggerdotdev/trigger.dev/blob/main/CONTRIBUTING.md)
- [x] The PR title follows the convention.
- [x] I ran and tested the code works
---
## Testing
- Reviewed the code flow for deployment rollback
(`ChangeCurrentDeploymentService`) and confirmed it was missing schedule
sync
- Verified all 4 callers of `ChangeCurrentDeploymentService` (UI
rollback, UI promote, API promote, finalize deployment) are now covered
- Ran `pnpm run typecheck --filter webapp` — passes cleanly
---
## Changelog
When rolling back (or manually promoting) a deployment, declarative
schedules were not being synced to match the target deployment's worker
metadata. Schedules remained as configured by the most recent deployment
rather than reflecting the target version's schedule configuration.
This fix adds a call to `syncDeclarativeSchedules` in
`ChangeCurrentDeploymentService` after the deployment promotion is
updated. It parses the target deployment's stored
`BackgroundWorkerMetadata` to restore the correct schedule state. This
covers both rollback and promote paths (UI and API). Errors are handled
gracefully so they don't block the deployment change itself.
---
## Screenshots
N/A — backend-only change.

## Summary
The v4.4.5 release PR (#3406) was merged before the automated
lockfile-update job in
[\`changesets-pr.yml\`](.github/workflows/changesets-pr.yml) could push
its commit. As a result main now has \`package.json\` bumped to
\`4.4.5\` but \`pnpm-lock.yaml\` still pinned to \`4.4.4\`.
This blocks every subsequent \`pnpm install --frozen-lockfile\` run,
including:
- \`release.yml\` for v4.4.5 publish ([run
#25217579660](https://github.com/triggerdotdev/trigger.dev/actions/runs/25217579660))
— never published packages to npm
- \`changesets-pr.yml\` on the next push to main ([run
#25217579645](https://github.com/triggerdotdev/trigger.dev/actions/runs/25217579645))
## Root cause (from CI logs)
\`\`\`
ERR_PNPM_OUTDATED_LOCKFILE Cannot install with "frozen-lockfile" because
pnpm-lock.yaml is not up to date with <ROOT>/packages/build/package.json
- @trigger.dev/core (lockfile: workspace:4.4.4, manifest:
workspace:4.4.5)
\`\`\`
Regenerated via \`pnpm install --lockfile-only\` against current main.
The diff is exactly what the canceled \`update-lockfile\` job would have
produced:
- 12 \`workspace:4.4.4\` → \`workspace:4.4.5\` specifier bumps
- pnpm metadata refresh (deprecation annotations on transitive deps, one
optional \`bufferutil\` peer resolution on \`react-email\`)
No new direct dependencies, no version drops.
## Follow-ups (separate PRs)
1. **Re-run release.yml** via \`workflow_dispatch\` (\`type: release\`,
\`ref\` = merge commit on main once this lands) to actually publish
4.4.5 to npm.
2. **Workflow fix** to prevent recurrence: fold the lockfile update into
\`changeset:version\` so the \`release-pr\` job creates a single commit
with version bumps + lockfile in sync. Removes the race window where the
release PR is mergeable before \`update-lockfile\` runs.
Dependabot's first auto-bump PR (#3495) was auto-closed because
`dependabot[bot]` isn't in the vouch list and isn't exempt from the
require-draft check.
Two changes:
- Add `dependabot[bot]` to `.github/VOUCHED.td` so the vouch check
passes.
- Add `dependabot[bot]` to the require-draft exception in
`vouch-check-pr.yml` (alongside `devin-ai-integration[bot]`) so its PRs
aren't closed for being non-draft.
Without both, dependabot bumps will keep getting closed and we lose the
weekly action update flow that #3494 set up.
## Summary
8 new features, 18 improvements, 11 bug fixes.
## Breaking changes
- Add server-side deprecation gate for deploys from v3 CLI versions
(gated by `DEPRECATE_V3_CLI_DEPLOYS_ENABLED`). v4 CLI deploys are
unaffected.
([#3415](https://github.com/triggerdotdev/trigger.dev/pull/3415))
## Improvements
- Add `--no-browser` flag to `init` and `login` to skip auto-opening the
browser during authentication. Also error loudly when `init` is run
without `--yes` under non-TTY stdin (previously default-and-exited
silently, leaving the project half-initialized). Both commands now show
an `Examples` section in `--help`.
([#3483](https://github.com/triggerdotdev/trigger.dev/pull/3483))
- Add `isReplay` boolean to the run context (`ctx.run.isReplay`),
derived from the existing `replayedFromTaskRunFriendlyId` database
field. Defaults to `false` for backwards compatibility.
([#3454](https://github.com/triggerdotdev/trigger.dev/pull/3454))
- Redact the `resolveWaitpoint` runtime log so it only emits `id` and
`type` instead of the full completed waitpoint. Previously the log
printed the entire waitpoint (including `output`) to stdout in
production runs, which could leak sensitive payloads. The value returned
by `wait.forToken()` is unchanged.
([#3490](https://github.com/triggerdotdev/trigger.dev/pull/3490))
- Add `SessionId` friendly ID generator and schemas for the new durable
Session primitive. Exported from `@trigger.dev/core/v3/isomorphic`
alongside `RunId`, `BatchId`, etc. Ships the
`CreateSessionStreamWaitpoint` request/response schemas alongside the
main Session CRUD.
([#3417](https://github.com/triggerdotdev/trigger.dev/pull/3417))
- Truncate large error stacks and messages to prevent OOM crashes. Stack
traces are capped at 50 frames (keeping top 5 + bottom 45 with an
omission notice), individual stack lines at 1024 chars, and error
messages at 1000 chars. Applied in parseError, sanitizeError, and OTel
span recording.
([#3405](https://github.com/triggerdotdev/trigger.dev/pull/3405))
## Server changes
These changes affect the self-hosted Docker image and Trigger.dev Cloud:
- Add a "Back office" tab to `/admin` and a per-organization detail page
at `/admin/back-office/orgs/:orgId`. The first action available on that
page is editing the org's API rate limit: admins can save a
`tokenBucket` override (refill rate, interval, max tokens) and see a
plain-English preview of the resulting sustained rate and burst
allowance. Writes are audit-logged via the server logger.
([#3434](https://github.com/triggerdotdev/trigger.dev/pull/3434))
- Optional `DEPLOY_REGISTRY_ECR_DEFAULT_REPOSITORY_POLICY` env var to
apply a default repository policy when the webapp creates new ECR repos
([#3467](https://github.com/triggerdotdev/trigger.dev/pull/3467))
- Ship the Errors page to all users, with a polish + bug-fix pass:
pinned "No channel" item in the Slack alert channel picker,
viewer-timezone alert timestamps via Slack's `<!date^>` token, Activity
sparkline peak tooltip, centered loading spinner and bug-icon empty
state on the error detail page, ellipsis on the Configure alerts
trigger.
([#3477](https://github.com/triggerdotdev/trigger.dev/pull/3477))
- Configure the set of machine presets to build boot snapshots for at
deploy time via `COMPUTE_TEMPLATE_MACHINE_PRESETS` (CSV of preset names,
default `small-1x`). Use `COMPUTE_TEMPLATE_MACHINE_PRESETS_REQUIRED`
(CSV, default = full PRESETS list) to scope which preset failures fail a
required-mode deploy. Optional preset failures are logged and don't
block the deploy.
([#3492](https://github.com/triggerdotdev/trigger.dev/pull/3492))
- Regenerating a RuntimeEnvironment API key no longer invalidates the
previous key immediately. The old key is recorded in a new
`RevokedApiKey` table with a 24 hour grace window, and
`findEnvironmentByApiKey` falls back to it when the submitted key
doesn't match any live environment. The grace window can be ended early
(or extended) by updating `expiresAt` on the row.
([#3420](https://github.com/triggerdotdev/trigger.dev/pull/3420))
- Add the `Session` primitive — a durable, task-bound, bidirectional I/O
channel that outlives a single run and acts as the run manager for
`chat.agent`. Ships the Postgres `Session` + `SessionRun` tables,
ClickHouse `sessions_v1` + replication service, the `sessions` JWT
scope, and the public CRUD + realtime routes (`/api/v1/sessions`,
`/realtime/v1/sessions/:session/:io`) including `end-and-continue` for
server-orchestrated run handoffs and session-stream waitpoints.
([#3417](https://github.com/triggerdotdev/trigger.dev/pull/3417))
- Add `KUBERNETES_POD_DNS_NDOTS_OVERRIDE_ENABLED` flag (off by default)
that overrides the cluster default and sets `dnsConfig.options.ndots` on
runner pods (defaulting to 2, configurable via
`KUBERNETES_POD_DNS_NDOTS`). Kubernetes defaults pods to `ndots: 5`, so
any name with fewer than 5 dots — including typical external domains
like `api.example.com` — is first walked through every entry in the
cluster search list (`<ns>.svc.cluster.local`, `svc.cluster.local`,
`cluster.local`) before being tried as-is, turning one resolution into
4+ CoreDNS queries (×2 with A+AAAA). Using a lower `ndots` value reduces
DNS query amplification in the `cluster.local` zone.
Note: before enabling, make sure no code path relies on search-list
expansion for names with dots ≥ the configured value — those names will
hit their as-is form first and could resolve externally before falling
back to the cluster search path.
([#3441](https://github.com/triggerdotdev/trigger.dev/pull/3441))
- Vercel integration option to disable auto promotions
([#3376](https://github.com/triggerdotdev/trigger.dev/pull/3376))
- Make it clear in the admin that feature flags are global and should
rarely be changed.
([#3408](https://github.com/triggerdotdev/trigger.dev/pull/3408))
- Admin worker groups API: add GET loader and expose more fields on
POST. ([#3390](https://github.com/triggerdotdev/trigger.dev/pull/3390))
- Add 60s fresh / 60s stale SWR cache to `getEntitlement` in
`platform.v3.server.ts`. Eliminates a synchronous billing-service HTTP
round trip on every trigger. Reuses the existing `platformCache` (LRU
memory + Redis) pattern already used for `limits` and `usage`. Cache key
is `${orgId}`. Errors return a permissive `{ hasAccess: true }` fallback
(existing behavior) and are also cached to prevent thundering-herd on
billing outages.
([#3388](https://github.com/triggerdotdev/trigger.dev/pull/3388))
- Show a `MicroVM` badge next to the region name on the regions page.
([#3407](https://github.com/triggerdotdev/trigger.dev/pull/3407))
- Increase default maximum project count per organization from 10 to 25
([#3409](https://github.com/triggerdotdev/trigger.dev/pull/3409))
- Merge execution snapshot creation into the dequeue taskRun.update
transaction, reducing 2 DB commits to 1 per dequeue operation
([#3395](https://github.com/triggerdotdev/trigger.dev/pull/3395))
- Add per-worker Node.js heap metrics to the OTel meter —
`nodejs.memory.heap.used`, `nodejs.memory.heap.total`,
`nodejs.memory.heap.limit`, `nodejs.memory.external`,
`nodejs.memory.array_buffers`, `nodejs.memory.rss`. Host-metrics only
publishes RSS, which overstates V8 heap by the external + native
footprint; these give direct heap visibility per cluster worker so
`NODE_MAX_OLD_SPACE_SIZE` can be sized against observed heap peaks
rather than RSS.
([#3437](https://github.com/triggerdotdev/trigger.dev/pull/3437))
- Tag Prisma spans with `db.datasource: "writer" | "replica"` so
monitors and trace queries can distinguish the writer pool from the
replica pool. Applies to all `prisma:engine:*` spans (including
`prisma:engine:connection` used by the connection-pool monitors) and the
outer `prisma:client:operation` span.
([#3422](https://github.com/triggerdotdev/trigger.dev/pull/3422))
- Clarify the cross-region intent in the Terraform and AI-prompt helpers
on the Add Private Connection page. Both already default
`supported_regions` to `["us-east-1", "eu-central-1"]`; added an inline
comment / parenthetical so the user understands why both regions are
listed (Trigger.dev runs in both, so the service must be consumable from
either).
([#3465](https://github.com/triggerdotdev/trigger.dev/pull/3465))
- Add `RUN_ENGINE_READ_REPLICA_SNAPSHOTS_SINCE_ENABLED` flag (default
off) to route the Prisma reads inside `RunEngine.getSnapshotsSince`
through the read-only replica client. Offloads the snapshot polling
queries (fired by every running task runner) from the primary. When
disabled, behavior is unchanged.
([#3423](https://github.com/triggerdotdev/trigger.dev/pull/3423))
- Stop creating TaskRunTag records and _TaskRunToTaskRunTag join table
entries during task triggering. The denormalized runTags string array on
TaskRun already stores tag names, making the M2M relation redundant
write overhead.
([#3369](https://github.com/triggerdotdev/trigger.dev/pull/3369))
- Stop writing per-tick state (`lastScheduledTimestamp`,
`nextScheduledTimestamp`, `lastRunTriggeredAt`) on `TaskSchedule` and
`TaskScheduleInstance`. The schedule engine now carries the previous
fire time forward via the worker queue payload, eliminating ~270K
dead-tuple-driven autovacuums per year on these hot tables and the
associated `IO:XactSync` mini-spikes on the writer. Customer-facing
`payload.lastTimestamp` semantics are unchanged.
([#3476](https://github.com/triggerdotdev/trigger.dev/pull/3476))
- Replace the expensive DISTINCT query for task filter dropdowns with a
dedicated TaskIdentifier registry table backed by Redis. Environments
migrate automatically on their next deploy, with a transparent fallback
to the legacy query for unmigrated environments. Also fixes duplicate
dropdown entries when a task changes trigger source, and adds
active/archived grouping for removed tasks. Moves BackgroundWorkerTask
reads in the trigger hot path to the read replica.
([#3368](https://github.com/triggerdotdev/trigger.dev/pull/3368))
- Public Access Tokens (PATs) minted before an API key rotation now keep
working during the 24h grace window. `validatePublicJwtKey` falls back
to any non-expired `RevokedApiKey` rows for the signing environment when
the primary signature check against the env's current `apiKey` fails.
The fallback query only runs on the failure path, so the hot success
path is unchanged.
([#3464](https://github.com/triggerdotdev/trigger.dev/pull/3464))
- Batch items that hit the environment queue size limit now fast-fail
without
retries and without creating pre-failed TaskRuns.
([#3352](https://github.com/triggerdotdev/trigger.dev/pull/3352))
- Show the cancel button in the runs list for runs in `DEQUEUED` status.
`DEQUEUED` was missing from `NON_FINAL_RUN_STATUSES` so the list hid the
button even though the single run page allowed it.
([#3421](https://github.com/triggerdotdev/trigger.dev/pull/3421))
- Reduce 5xx feedback loops on hot debounce keys by quantizing
`delayUntil`,
adding an unlocked fast-path skip, and gracefully handling redlock
contention in `handleDebounce` so the SDK no longer retries into a herd.
([#3453](https://github.com/triggerdotdev/trigger.dev/pull/3453))
- Fix RSS memory leak in the realtime proxy routes. `/realtime/v1/runs`,
`/realtime/v1/runs/:id`, and `/realtime/v1/batches/:id` called `fetch()`
into Electric with no abort signal, so when a client disconnected mid
long-poll, undici kept the upstream socket open and buffered response
chunks that would never be consumed — retained only in RSS, invisible to
V8 heap tooling. Thread `getRequestAbortSignal()` through
`RealtimeClient.streamRun/streamRuns/streamBatch` to `longPollingFetch`
and cancel the upstream body in the error path. Isolated reproducer
showed ~44 KB retained per leaked request; signal propagation releases
it cleanly.
([#3442](https://github.com/triggerdotdev/trigger.dev/pull/3442))
- Fix memory leak where every aborted SSE connection pinned the full
request/response graph on Node 20, caused by `AbortSignal.any()` in
`sse.ts` retaining its source signals indefinitely (see
nodejs/node#54614, nodejs/node#55351). Also clear the
`setTimeout(abort)` timer in `entry.server.tsx` so successful HTML
renders don't pin the React tree for 30s per request.
([#3430](https://github.com/triggerdotdev/trigger.dev/pull/3430))
- Preserve filters on the queues page when submitting modal actions.
([#3471](https://github.com/triggerdotdev/trigger.dev/pull/3471))
- Fix Redis connection leak in realtime streams and broken abort signal
propagation.
**Redis connections**: Non-blocking methods (ingestData, appendPart,
getLastChunkIndex) now share a single Redis connection instead of
creating one per request. streamResponse still uses dedicated
connections (required for XREAD BLOCK) but now tears them down
immediately via disconnect() instead of graceful quit(), with a 15s
inactivity fallback.
**Abort signal**: request.signal is broken in Remix/Express due to a
Node.js undici GC bug (nodejs/node#55428) that severs the signal chain
when Remix clones the Request internally. Added getRequestAbortSignal()
wired to Express res.on("close") via httpAsyncStorage, which fires
reliably on client disconnect. All SSE/streaming routes updated to use
it. ([#3399](https://github.com/triggerdotdev/trigger.dev/pull/3399))
- Prevent dashboard crash (React error #31) when span accessory item
text is not a string. Filters out malformed accessory items in
SpanCodePathAccessory instead of passing objects to React as children.
([#3400](https://github.com/triggerdotdev/trigger.dev/pull/3400))
- Upgrade Remix packages from 2.1.0 to 2.17.4 to address security
vulnerabilities in React Router
([#3372](https://github.com/triggerdotdev/trigger.dev/pull/3372))
- Fix Vercel integration settings page (remove redundant section
toggles) and improve the Vercel onboarding flow so the modal closes
after connecting a GitHub repo and the marketplace `next` URL is
preserved across the GitHub app install redirect.

## trigger.dev@4.4.5
### Patch Changes
- Add `--no-browser` flag to `init` and `login` to skip auto-opening the
browser during authentication. Also error loudly when `init` is run
without `--yes` under non-TTY stdin (previously default-and-exited
silently, leaving the project half-initialized). Both commands now show
an `Examples` section in `--help`.

## @trigger.dev/core@4.4.5
### Patch Changes
- Add `isReplay` boolean to the run context (`ctx.run.isReplay`),
derived from the existing `replayedFromTaskRunFriendlyId` database
field. Defaults to `false` for backwards compatibility.
([#3454](https://github.com/triggerdotdev/trigger.dev/pull/3454))
- Redact the `resolveWaitpoint` runtime log so it only emits `id` and
`type` instead of the full completed waitpoint. Previously the log
printed the entire waitpoint (including `output`) to stdout in
production runs, which could leak sensitive payloads. The value returned
by `wait.forToken()` is unchanged.
([#3490](https://github.com/triggerdotdev/trigger.dev/pull/3490))
- Add `SessionId` friendly ID generator and schemas for the new durable
Session primitive. Exported from `@trigger.dev/core/v3/isomorphic`
alongside `RunId`, `BatchId`, etc. Ships the
`CreateSessionStreamWaitpoint` request/response schemas alongside the
main Session CRUD.
([#3417](https://github.com/triggerdotdev/trigger.dev/pull/3417))
- Truncate large error stacks and messages to prevent OOM crashes. Stack
traces are capped at 50 frames (keeping top 5 + bottom 45 with an
omission notice), individual stack lines at 1024 chars, and error
messages at 1000 chars. Applied in parseError, sanitizeError, and OTel
span recording.

The webapp's compute template creation hardcoded a single machine preset
(`small-1x`) at deploy time, regardless of which presets a project
actually uses. Tasks running on any other preset paid full cold-snapshot
creation cost on first run.
Two new env vars:
- `COMPUTE_TEMPLATE_MACHINE_PRESETS` - CSV of preset names to build boot
snapshots for during deploy. Defaults to `small-1x` so existing deploys
don't change behavior.
- `COMPUTE_TEMPLATE_MACHINE_PRESETS_REQUIRED` - CSV of presets whose
failure fails a required-mode deploy. Defaults to the full `PRESETS`
list. Optional preset failures are logged but don't block the deploy.
The compute client now sends the multi-config request shape; the service
evaluates per-preset outcomes against the required set and surfaces a
combined failure message when a required preset fails.
Both env vars are validated at boot via the env schema - unknown preset
names or `_REQUIRED` entries that aren't a subset of `_PRESETS` fail
loudly at startup rather than silently per-deploy.
Most actions in this repo were several major versions behind, which is
why every CI run has been emitting Node 20 deprecation warnings.
Pinning every action to a commit SHA (with the version as a trailing
comment) means each CI run uses the exact code that was reviewed when
the bump landed, instead of whatever a maintainer last pointed the major
tag at. Dependabot is configured to group all action bumps into one
weekly PR with a 7-day cooldown.
Worth flagging:
- The Claude Code action ships ~daily but the model is set separately
via `--model` in `claude_args`, so SHA-pinning the action gives
reproducibility without locking the model.
- The kubeconform container is digest-pinned
(`docker://image:tag@sha256:...`). Dependabot's github-actions ecosystem
doesn't track `docker://` references ([explicit TODO in
dependabot-core](https://github.com/dependabot/dependabot-core/blob/main/github_actions/lib/dependabot/github_actions/file_parser.rb)),
so it needs manual bumps either way - but the digest pin protects
against tag repointing for free.
Redact the `resolveWaitpoint` runtime log so it only emits `id` and
`type` instead of the full completed waitpoint. Previously the log
printed the entire waitpoint (including `output`) to stdout in
production runs, which could leak sensitive payloads. The value returned
by `wait.forToken()` is unchanged.
The Activity peak count tooltip in the errors list rendered a `<button>`
(from `SimpleTooltip`'s default `TooltipTrigger`) inside the row's `<a>`
link (`TableCell to={errorPath}`). Interactive content nested inside
other interactive content is invalid HTML and triggers accessibility
warnings. Adding `asChild` to `SimpleTooltip` makes the existing
`<span>` the trigger directly, removing the nested `<button>`.
Closes the most common friction point hit while setting up a fresh
project from an agent harness: the CLI auto-opens the user's default
browser during auth and there is no supported way to skip it (the
existing `isLinuxServer()` path only triggers when `xdg-open` is missing
entirely).
`--no-browser` on `login` and `init` prints the URL and waits to be
visited from any browser. The flag threads through the embedded
`login()` call inside `init`.
While here:
- `init` now errors loudly when stdin is non-TTY without `--yes` instead
of default-and-exiting silently at the first prompt (which left the
project half-initialized: deps installed, no config or example file).
- Both commands gain an `Examples` block in `--help` rendered between
the description and the arguments/options list, so `--help | head`
surfaces the common invocations.
Other commands also call `login()` embedded and would benefit from
`--no-browser` too, but kept this PR scoped to the cases the friction
log called out.
## Summary
Each scheduled-task tick previously issued **3 Prisma `UPDATE`s**
against
`TaskSchedule.lastRunTriggeredAt`,
`TaskScheduleInstance.lastScheduledTimestamp`,
and `TaskScheduleInstance.nextScheduledTimestamp`. All three were pure
denormalization — every value can be derived without persisting.
After this PR `TaskSchedule` and `TaskScheduleInstance` become **near
read-only**:
writes happen only on schedule create / update / delete (rare admin
actions),
so the per-tick autovacuum churn on these hot tables disappears.
## Design
The previous fire time travels forward through the **schedule worker
payload**,
not through the database. Concretely:
- The `schedule.triggerScheduledTask` worker payload gains an optional
`lastScheduleTime: z.coerce.date().optional()` field.
- When the engine fires a schedule, it re-enqueues the next tick with
`lastScheduleTime = scheduleTimestamp` (the just-fired time).
- When the next tick dequeues, `payload.lastTimestamp` is sourced from
`params.lastScheduleTime` directly. No DB round-trip, no cron-derivation
drift across DST boundaries, no caveats around recently-edited cron
expressions.
`payload.lastTimestamp` keeps its `Date | undefined` SDK shape.
First-ever
fires still report `undefined`, so customer `if
(!payload.lastTimestamp)`
first-run patterns keep working.
For Redis jobs that were enqueued **before** this change (which lack
`lastScheduleTime` in their payload), the engine falls back to
`instance.lastScheduledTimestamp` once. Once those drain, the column is
never read again. Revert is code-only; the columns stay in place and can
be dropped in a follow-up once the rollout is stable.
## Files
- `internal-packages/schedule-engine/*` — engine refactor,
`workerCatalog`
schema field, `TriggerScheduleParams` extension, tests updated to assert
on the worker-payload flow rather than DB readbacks.
- `internal-packages/database/prisma/schema.prisma` — `/// @deprecated`
triple-slash docstrings on the three columns. No migration.
- `apps/webapp/app/presenters/v3/ScheduleListPresenter.server.ts` —
drops
the `lastRunTriggeredAt` Prisma select; "Last run" cell is approximated
from the cron expression's previous slot, gated on `schedule.createdAt`
so brand-new schedules show "–". UI is best-effort; the runs page is the
source of truth.
- `apps/webapp/app/v3/utils/calculateNextSchedule.server.ts` — adds a
`previousScheduledTimestamp` helper for the UI cell above. Public API
responses (`api.v1.schedules.*`) already compute `nextRun` from cron and
don't expose `lastTimestamp` — no public API change.
- `references/scheduled-tasks/` — new reference project with declarative
schedules at multiple cadences and three throw-on-fail validators
(`first-fire-detector`, `interval-validator`, `upcoming-validator`) for
E2E-verifying the worker-payload flow.
Refs TRI-8891
## Test plan
- [x] `pnpm run typecheck --filter @internal/schedule-engine --filter
webapp`
- [x] `pnpm run build --filter @trigger.dev/core`
- [x] `pnpm run test --filter @internal/schedule-engine` — integration
test
asserts first-fire `lastTimestamp === undefined`, second fire carries
the previous fire's timestamp exactly.
- [x] E2E against local webapp via `references/scheduled-tasks`:
- Fresh schedules attached → all three deprecated columns stay `NULL`
after
multiple fires.
- Redis payload at second fire contains
`"lastScheduleTime":"<previous fire timestamp>"`.
- `TaskRun.payload` and the every-minute task's returned output both
confirm
`lastTimestamp = null` on first fire and `lastTimestamp = <prev fire>`
on
second fire, exactly 60s apart.
- All three throw-on-FAIL validators completed successfully on every
non-first fire.
- [x] Schedules REST API end-to-end (`POST` / `GET` / `PUT` / `activate`
/
`deactivate` / `DELETE`) — `nextRun` recomputed live from cron + tz on
every response, no reads of deprecated columns.
## What this does
Polish + bug-fix pass on the Errors page so it can ship to everyone.
Touches the Slack alert config UX, errors list, error detail page, and
unhides the SideMenu entry for non-admins.
## Decisions
**"No channel" item over standalone Remove button**
Chose pinning a `<XMarkIcon /> No channel` `SelectItem` above the
channel list. Rejected the standalone "Remove channel" link in a
`<Hint>` — color/hover behaviour clashed with the sibling `<TextLink>`,
and "channel selection" is the right context for clearing. Server action
already deletes the channel when `slackChannel=""` is submitted.
**Slack `<!date^>` token over per-user TZ field for alerts**
Chose Slack's native `<!date^TS^…>` token so each viewer sees timestamps
in their own timezone (UTC fallback). Rejected per-user/per-org TZ
schema work — works for multi-region channels for free. Email/dashboard
TZ source-of-truth filed as TRI-8885 / TRI-8886.
**Make errors GA**
## Summary
`POST /api/v1/sessions` was secret-key-only because the customer browser
flow runs through `chat.createStartSessionAction` (server-side, holds
the secret key). But the `cli-v3` MCP `start_agent_chat` tool is itself
a server-side surface — developer's CLI/IDE acting as their own server —
and only holds a JWT minted from the user's PAT. Without JWT support on
this route the entire MCP agent toolkit (`start_agent_chat`,
`send_agent_message`, `close_agent_chat`) is blocked at session
creation.
Add `allowJWT: true` plus an `authorization` block requiring the
`write:sessions` (or `admin`) super-scope.
## Why a wildcard `sessions` resource
Resource scoping by `taskIdentifier` isn't possible at auth-resolve time
— action routes don't pass `body` to the `resource` callback, and the
task name only lives in the body. So the resource is `sessions: "*"` and
the super-scope does the actual gating. The JWT-issuer (cli-v3 MCP,
customer servers wrapping their own auth helpers, etc.) decides which
scopes to mint, which is where per-task narrowing lives.
## Test plan
- [x] Verified end-to-end against local:
`mcp__trigger__start_agent_chat` → `send_agent_message("pong")` →
`send_agent_message("echo")` → `close_agent_chat` all succeed. Two
assistant turns reuse the same runId (continuation in the idle window).
- [ ] Browser-mediated `chat.createStartSessionAction` flow continues to
work unchanged (still uses secret-key path under the hood).
- [ ] Loader (GET) and other session routes — unchanged, no scope drift.
## Notes
This unblocks T17 in the [ai-chat e2e smoke
catalog](https://github.com/triggerdotdev/trigger.dev/blob/feature/tri-7532-ai-sdk-chat-transport-and-chat-task-system/.claude/skills/ai-chat-e2e/SMOKE-TESTS.md)
(which lives in the feature branch's skill catalog, not this repo).
Pairs with the cli-v3 MCP fix on the feature branch (`feat: AI SDK
custom useChat transport & chat.task harness`, PR #3173) — that PR's
`agentChat.ts` change makes the call shape correct (`taskIdentifier` +
`triggerConfig`); this PR opens the door for the JWT to actually pass.
## Summary
Self-hosters that operate the webapp's ECR account separately from the
account running the EKS workers (e.g., a shared platform account that
hosts the registry plus per-team accounts that host clusters) currently
hit a 403 Forbidden the first time **any** project is deployed:
```
Failed to pull image "<acct-A>.dkr.ecr.<region>.amazonaws.com/<namespace>/proj_…:…":
unexpected status from HEAD request to .../v2/.../manifests/sha256:…: 403 Forbidden
```
`ensureEcrRepositoryExists` in
`apps/webapp/app/v3/getDeploymentImageRef.server.ts` calls
`CreateRepository` and `PutLifecyclePolicy`, but never
`SetRepositoryPolicy` — so the new repo inherits the AWS default (only
the registry-owner account can read/pull). Workers in the cluster
account get 403 every single deploy. The only workarounds today are
running a one-off post-create script or pre-creating every repo by hand.
## Proposed change
Add an optional env var:
```
DEPLOY_REGISTRY_ECR_DEFAULT_REPOSITORY_POLICY (V4 mirror: V4_DEPLOY_REGISTRY_ECR_DEFAULT_REPOSITORY_POLICY)
```
Raw IAM policy JSON. When set, the webapp calls `SetRepositoryPolicy`
immediately after `CreateRepository` so every new repo carries that
policy from creation. Operators control the principal/actions; we don't
bake in any opinions about cross-account boundaries.
Example value (for the typical self-host case — grant pull to the
cluster account):
```json
{
"Version": "2012-10-17",
"Statement": [{
"Sid": "AllowClusterAccountPull",
"Effect": "Allow",
"Principal": {"AWS": "arn:aws:iam::<cluster-account-id>:root"},
"Action": [
"ecr:GetDownloadUrlForLayer",
"ecr:BatchGetImage",
"ecr:BatchCheckLayerAvailability"
]
}]
}
```
## Why env var (not a chart-level field)
- Mirrors the shape of the sibling vars (`DEPLOY_REGISTRY_ECR_TAGS`,
`DEPLOY_REGISTRY_ECR_ASSUME_ROLE_ARN`, etc.) which are already
operator-supplied via `webapp.extraEnvVars` in self-host setups.
- Cloud is unaffected — the env var is optional, unset by default;
existing behavior unchanged.
- Existing repos are unaffected — only newly-created repos get the
policy.
- `RepositoryCreationTemplate` from the AWS provider isn't an
alternative here: it only applies to repos created via
pull-through-cache or replication, not to `ecr:CreateRepository` API
calls.
## Implementation
- `apps/webapp/app/env.server.ts` — declare
`DEPLOY_REGISTRY_ECR_DEFAULT_REPOSITORY_POLICY` and the V4 fallback.
- `apps/webapp/app/v3/registryConfig.server.ts` — propagate
`ecrDefaultRepositoryPolicy` to `RegistryConfig`.
- `apps/webapp/app/v3/getDeploymentImageRef.server.ts` —
`createEcrRepository` accepts the policy; if set, calls
`SetRepositoryPolicy` after `PutLifecyclePolicy`.
- `docs/self-hosting/env/webapp.mdx` — documentation row added under
**Deploy & Registry**.
## Verification
Verified end-to-end against a self-hosted Trigger.dev on EKS where the
ECR account is separate from the cluster account:
- **Without the env var** (current `main`): the new project's first run
pod stays in `ImagePullBackOff` with `403 Forbidden`.
- **With the env var set** to a JSON granting
`ecr:BatchGetImage`/`GetDownloadUrlForLayer`/`BatchCheckLayerAvailability`
to the cluster account: a fresh `trigger.dev deploy --env prod` followed
by a `hello-world` run completes in ~5s end-to-end on the first try.
Manually also confirmed that existing repos are untouched (the call only
fires inside `createEcrRepository`, which only runs when
`DescribeRepositories` returned `RepositoryNotFoundException`).
## Out of scope
- Chart values surface for this — operators already pass the existing
ECR vars via `webapp.extraEnvVars`, so this follows the same pattern.
Happy to add a first-class chart field in a follow-up if that's the
preferred direction.
- IAM-policy validation in the webapp — we forward the JSON verbatim to
AWS and surface AWS's error messages on misuse, matching how
`DEPLOY_REGISTRY_ECR_TAGS` is handled today.
This is a draft pending CI / CodeRabbit pass — happy to iterate on
direction (e.g., split into per-action env vars, or extend the chart
values schema) if any of the above choices feels off.

Add `isReplay` boolean to the run context (`ctx.run.isReplay`), derived from the existing `replayedFromTaskRunFriendlyId` database field. Defaults to `false` for backwards compatibility.
Add Agent Skills for `chat.agent`. Drop a folder with a `SKILL.md` and any helper scripts/references next to your task code, register it with `skills.define({ id, path })`, and the CLI bundles it into the deploy image automatically — no `trigger.config.ts` changes. The agent gets a one-line summary in its system prompt and discovers full instructions on demand via `loadSkill`, with `bash` and `readFile` tools scoped per-skill (path-traversal guards, output caps, abort-signal propagation).
Built on the [AI SDK cookbook pattern](https://ai-sdk.dev/cookbook/guides/agent-skills) — portable across providers. SDK + CLI only for now; dashboard-editable `SKILL.md` text is on the roadmap.
**AI Prompts** — define prompt templates as code alongside your tasks, version them on deploy, and override the text or model from the dashboard without redeploying. Prompts integrate with the Vercel AI SDK via `toAISDKTelemetry()` (links every generation span back to the prompt) and with `chat.agent` via `chat.prompt.set()` + `chat.toStreamTextOptions()`.
```ts
import{prompts}from"@trigger.dev/sdk";
import{generateText}from"ai";
import{openai}from"@ai-sdk/openai";
import{z}from"zod";
exportconstsupportPrompt=prompts.define({
id:"customer-support",
model:"gpt-4o",
config:{temperature: 0.7},
variables: z.object({
customerName: z.string(),
plan: z.string(),
issue: z.string(),
}),
content:`You are a support agent for Acme.
Customer: {{customerName}} ({{plan}} plan)
Issue: {{issue}}`,
});
constresolved=awaitsupportPrompt.resolve({
customerName:"Alice",
plan:"Pro",
issue:"Can't access billing",
});
constresult=awaitgenerateText({
model: openai(resolved.model??"gpt-4o"),
system: resolved.text,
prompt:"Can't access billing",
...resolved.toAISDKTelemetry(),
});
```
**What you get:**
- **Code-defined, deploy-versioned templates** — define with `prompts.define({ id, model, config, variables, content })`. Every deploy creates a new version visible in the dashboard. Mustache-style placeholders (`{{var}}`, `{{#cond}}...{{/cond}}`) with Zod / ArkType / Valibot-typed variables.
- **Dashboard overrides** — change a prompt's text or model from the dashboard without redeploying. Overrides take priority over the deployed "current" version and are environment-scoped (dev / staging / production independent).
- **Resolve API** — `prompt.resolve(vars, { version?, label? })` returns the compiled `text`, resolved `model`, `version`, and labels. Standalone `prompts.resolve<typeof handle>(slug, vars)` for cross-file resolution with full type inference on slug and variable shape.
- **AI SDK integration** — spread `resolved.toAISDKTelemetry({ ...extra })` into any `generateText` / `streamText` call and every generation span links to the prompt in the dashboard alongside its input variables, model, tokens, and cost.
- **`chat.agent` integration** — `chat.prompt.set(resolved)` stores the resolved prompt run-scoped; `chat.toStreamTextOptions({ registry })` pulls `system`, `model` (resolved via the AI SDK provider registry), `temperature` / `maxTokens` / etc., and telemetry into a single spread for `streamText`.
- **Dashboard** — prompts list with per-prompt usage sparklines; per-prompt detail with Template / Details / Versions / Generations / Metrics tabs. AI generation spans get a custom inspector showing the linked prompt's metadata, input variables, and template content alongside model, tokens, cost, and the message thread.
See [/docs/ai/prompts](https://trigger.dev/docs/ai/prompts) for the full reference — template syntax, version resolution order, override workflow, and type utilities (`PromptHandle`, `PromptIdentifier`, `PromptVariables`).
Adds AI SDK 7 support. The `ai` peer range now includes v7, and the `chat.agent` / chat surfaces work against v7's ESM-only build. On v7, install `@ai-sdk/otel` alongside `ai` and the SDK registers it for you so `experimental_telemetry` spans keep flowing into your run traces (v7 stopped emitting them from `ai` core). v5 and v6 keep working unchanged.
Add `ai.toolExecute(task)` so you can wire a Trigger subtask in as the `execute` handler of an AI SDK `tool()` while defining `description` and `inputSchema` yourself — useful when you want full control over the tool surface and just need Trigger's subtask machinery for the body.
```ts
constmyTool=tool({
description:"...",
inputSchema: z.object({...}),
execute: ai.toolExecute(mySubtask),
});
```
`ai.tool(task)` (`toolFromTask`) keeps doing the all-in-one wrap and now aligns its return type with AI SDK's `ToolSet`. Minimum `ai` peer raised to `^6.0.116` to avoid cross-version `ToolSet` mismatches in monorepos.
Fix `chat.agent` skills silently missing in `trigger dev` for projects whose task files read `process.env` at module top level (e.g. a third-party SDK client initialized at import). Skill folders now bundle into `.trigger/skills/` reliably regardless of which env vars are set when the CLI launches.
Reject overlong `idempotencyKey` values at the API boundary so they no longer trip an internal size limit on the underlying unique index and surface as a generic 500. Inputs are capped at 2048 characters — well above what `idempotencyKeys.create()` produces (a 64-character hash) and above any realistic raw key. Applies to `tasks.trigger`, `tasks.batchTrigger`, `batch.create` (Phase 1 streaming batches), `wait.createToken`, `wait.forDuration`, and the input/session stream waitpoint endpoints. Over-limit requests now return a structured 400 instead.
Reliability fixes for `chat.agent`. A user message sent while the agent is streaming is no longer delivered twice (which could run a duplicate turn), input appends now carry an idempotency key so a retried send can't duplicate a message, stopping a generation clears the streaming state so a page reload doesn't replay the stopped turn, and runs can now carry the full set of dashboard tags instead of being silently truncated. `onTurnComplete` now fires on errored turns (with the thrown error attached) and the failed turn's user message is persisted so it isn't lost on the next run. Custom agents and manual `chat.writeTurnComplete` callers now trim the output stream, sending a custom action no longer leaves a second stream reader running, and a long-lived `watch` subscription no longer grows its dedupe set without bound.
Adds `onBoot` to `chat.agent` — a lifecycle hook that fires once per worker process picking up the chat. Runs for the initial run, preloaded runs, AND reactive continuation runs (post-cancel, crash, `endRun`, `requestUpgrade`, OOM retry), before any other hook. Use it to initialize `chat.local`, open per-process resources, or re-hydrate state from your DB on continuation — anywhere the SAME run picking up after suspend/resume isn't enough.
Use `onBoot` (not `onChatStart`) for state setup that must run every time a worker picks up the chat — `onChatStart` fires once per chat and won't run on continuation, leaving `chat.local` uninitialized when `run()` tries to use it.
Add a `tools` option to `chat.agent`. Declaring your tools here threads them into the SDK's internal `convertToModelMessages`, so each tool's `toModelOutput` is re-applied when prior-turn history is re-converted.
**AI Agents** — run AI SDK chat completions as durable Trigger.dev agents instead of fragile API routes. Define an agent in one function, point `useChat` at it from React, and the conversation survives page refreshes, network blips, and process restarts.
- **AI SDK `useChat` integration** — a custom [`ChatTransport`](https://sdk.vercel.ai/docs/ai-sdk-ui/transport) (`useTriggerChatTransport`) plugs straight into Vercel AI SDK's `useChat` hook. Text streaming, tool calls, reasoning, and `data-*` parts all work natively over Trigger.dev's realtime streams. No custom API routes needed.
- **First-turn fast path (`chat.headStart`)** — opt-in handler that runs the first turn's `streamText` step in your warm server process while the agent run boots in parallel, cutting cold-start TTFC by roughly half (measured 2801ms → 1218ms on `claude-sonnet-4-6`). The agent owns step 2+ (tool execution, persistence, hooks) so heavy deps stay where they belong. Web Fetch handler works natively in Next.js, Hono, SvelteKit, Remix, Workers, etc.; bridge to Express/Fastify/Koa via `chat.toNodeListener`. New `@trigger.dev/sdk/chat-server` subpath.
- **Multi-turn durability via Sessions** — every chat is backed by a durable Session that outlives any individual run. Conversations resume across page refreshes, idle timeout, crashes, and deploys; `resume: true` reconnects via `lastEventId` so clients only see new chunks. `sessions.list` enumerates chats for inbox-style UIs.
- **Auto-accumulated history, delta-only wire** — the backend accumulates the full conversation across turns; clients only ship the new message each turn. Long chats never hit the 512 KiB body cap. Register `hydrateMessages` to be the source of truth yourself.
- **Lifecycle hooks** — `onPreload`, `onChatStart`, `onValidateMessages`, `hydrateMessages`, `onTurnStart`, `onBeforeTurnComplete`, `onTurnComplete`, `onChatSuspend`, `onChatResume` — for persistence, validation, and post-turn work.
- **Stop generation** — client-driven `transport.stopGeneration(chatId)` aborts mid-stream; the run stays alive for the next message, partial response is captured, and aborted parts (stuck `partial-call` tools, in-progress reasoning) are auto-cleaned.
- **Tool approvals (HITL)** — tools with `needsApproval: true` pause until the user approves or denies via `addToolApprovalResponse`. The runtime reconciles the updated assistant message by ID and continues `streamText`.
- **Steering and background injection** — `pendingMessages` injects user messages between tool-call steps so users can steer the agent mid-execution; `chat.inject()` + `chat.defer()` adds context from background work (self-review, RAG, safety checks) between turns.
- **Actions** — non-turn frontend commands (undo, rollback, regenerate, edit) sent via `transport.sendAction`. Fire `hydrateMessages` + `onAction` only — no turn hooks, no `run()`. `onAction` can return a `StreamTextResult` for a model response, or `void` for side-effect-only.
- **Typed state primitives** — `chat.local<T>` for per-run state accessible from hooks, `run()`, tools, and subtasks (auto-serialized through `ai.toolExecute`); `chat.store` for typed shared data between agent and client; `chat.history` for reading and mutating the message chain; `clientDataSchema` for typed `clientData` in every hook.
- **`chat.toStreamTextOptions()`** — one spread into `streamText` wires up versioned system [Prompts](https://trigger.dev/docs/ai/prompts), model resolution, telemetry metadata, compaction, steering, and background injection.
- **Multi-tab coordination** — `multiTab: true` + `useMultiTabChat` prevents duplicate sends and syncs state across browser tabs via `BroadcastChannel`. Non-active tabs go read-only with live updates.
- **Network resilience** — built-in indefinite retry with bounded backoff, reconnect on `online` / tab refocus / bfcache restore, `Last-Event-ID` mid-stream resume. No app code needed.
See [/docs/ai-chat](https://trigger.dev/docs/ai-chat/overview) for the full surface — quick start, three backend approaches (`chat.agent`, `chat.createSession`, raw task), persistence and code-sandbox patterns, type-level guides, and API reference.
Continuation chat boots no longer stall for around 10 seconds before the first turn. The `session.in` resume cursor is now found with a non-blocking records read instead of draining an SSE long-poll (which always waited out its full 5 second inactivity window, twice per boot), the boot reads run concurrently, and chat snapshots carry the cursor so subsequent boots skip the scan entirely.
Fix `chat.headStart` when `hydrateMessages` is registered. The warm route's step-1 partial now reaches the agent's accumulator on the hydrate path, so `onTurnComplete` carries the full first turn (the head-start user message included), tool-call handovers resume from step 2 instead of re-running step 1, and the assistant `messageId` stays stable across the handover.
Preserve reasoning parts across the `chat.headStart` handover. Extended-thinking models' step-1 reasoning now lands in the durable session history (and `onTurnComplete`) under the same assistant `messageId`, with provider metadata intact so Anthropic thinking signatures survive replays.
Add read primitives to `chat.history` for HITL flows: `getPendingToolCalls()`, `getResolvedToolCalls()`, `extractNewToolResults(message)`, `getChain()`, and `findMessage(messageId)`. These lift the accumulator-walking logic that customers building human-in-the-loop tools were re-implementing into the SDK.
Use `getPendingToolCalls()` to gate fresh user turns while a tool call is awaiting an answer. Use `extractNewToolResults(message)` to dedup tool results when persisting to your own store — the helper returns only the parts whose `toolCallId` is not already resolved on the chain.
```ts
constpending=chat.history.getPendingToolCalls();
if(pending.length>0){
// an addToolOutput is expected before a new user message
Stamp `gen_ai.conversation.id` (the chat id) on every span and metric emitted from inside a `chat.task` or `chat.agent` run. Lets you filter dashboard spans, runs, and metrics by the chat conversation that produced them — independent of the run boundary, so multi-run chats correlate cleanly. No code changes required on the user side.
Fix `chat.agent` HITL continuations on reasoning-heavy turns. Two changes that work together:
- The per-turn merge now overlays the wire copy's tool-part state advancement onto the agent's existing chain — `state` + the matching resolution field (`output` / `errorText` / `approval`) come from the wire, everything else (text, reasoning, tool `input`, provider metadata) stays whatever the snapshot or `hydrateMessages` returned. Previously a full-message replace overwrote those fields with whatever the client shipped, so a slimmed wire copy landed a tool call with no `arguments` on the next LLM call. Covers `output-available` / `output-error` (HITL `addToolOutput`) and `approval-responded` / `output-denied` (approval flow).
-`TriggerChatTransport.sendMessages` and `AgentChat.sendRaw` now slim assistant messages that carry advanced tool parts. The wire payload is just `{ id, role, parts: [<state + resolution field>] }` for `submit-message` continuations; everything else passes through. Reasoning blobs and full tool inputs no longer ride the wire on every `addToolOutput` / `addToolApproveResponse`, so continuation payloads stay well under the `.in/append` cap on long agent loops.
Note: `onValidateMessages` receives the slim wire on HITL turns. If you call `validateUIMessages` from `ai` against the full `messages` array it will reject the slim assistant; filter to user messages (or skip on HITL turns) — see the updated docstring on `onValidateMessages` for the recommended pattern.
For `hydrateMessages` hooks that persist the chain, this release also adds a small helper to the `@trigger.dev/sdk/ai` surface:
It pushes fresh user messages by id, no-ops on HITL continuations (the incoming shares an id with the existing assistant — the runtime overlays the new tool-state advance), and skips on non-`submit-message` triggers. Returns `true` if it mutated `stored` so the caller knows whether to persist.
Net effect: `chat.addToolOutput(...)` / `chat.addToolApproveResponse(...)` on multi-step reasoning agents (OpenAI Responses with `store: false`, Anthropic extended thinking, etc.) no longer blows the cap and no longer corrupts the LLM input.
`ChatStartSessionParams` gains a typed `clientData` field — folded into the first run's `payload.metadata` so `onPreload` / `onChatStart` see the same shape per-turn `metadata` carries via the transport. The opaque session-level `metadata` field is unchanged.
`trigger init` now sets up your AI coding assistant as part of project setup: pick the MCP server, the agent skills, or both, then scaffold with the CLI or hand off to your assistant. Adds a new `getting-started` agent skill that teaches assistants how to bootstrap Trigger.dev (install the SDK, write `trigger.config.ts`, create a first task, run `trigger dev`), so the AI-driven setup path works end to end. It ships in the CLI alongside the existing skills, version-matched to your SDK.
Coerce numeric `concurrencyKey` values to string at the API boundary across `tasks.trigger`, `tasks.batchTrigger`, and the Phase-2 streaming batch endpoint.
Fix two `chat.createSession()` bugs: stopping a generation no longer wedges the run (the turn loop raced a `totalUsage` promise that never settles after a stop-abort), and continuation runs now wait for the next message instead of invoking the model with an empty prompt.
Record client-side dequeue API latency in the supervisor consumer pool as a Prometheus histogram (`queue_consumer_pool_dequeue_duration_seconds`, labelled by `outcome`: success/empty/error).
`dev` and `deploy` now fail with a clear error when two tasks are defined with the same id, including across different task types (e.g. a scheduled task and a regular task sharing an id). Previously the second definition silently overwrote the first, so one of the tasks would vanish with no warning. Task ids are detected as duplicates during indexing (naming each offending id and the files it was found in), and the same rule is enforced server-side when the background worker is registered.
Fix `@trigger.dev/core` build: cast the underlying log record exporter when calling `forceFlush` so it typechecks against the updated OpenTelemetry `LogRecordExporter` type (which no longer declares `forceFlush`).
`envvars.upload` now accepts an optional `isSecret` flag, letting you create the imported variables as secret (redacted) environment variables. When omitted, variables default to non-secret.
Offload large trigger payloads to object storage before sending the trigger API request. The SDK uploads packets at or above the existing 128KB limit and sends an `application/store` pointer instead of embedding large JSON in the request body. `TriggerTaskRequestBody` now validates that `application/store` payloads are non-empty storage paths.
Payload uploads use the same resolved `ApiClient` as the trigger call (including `requestOptions.clientConfig`), not only the global `apiClientManager.client` — so custom `baseURL`, access token, and preview branch apply to both presign and trigger.
Fix `LocalsKey<T>` type incompatibility across dual-package builds. The phantom value-type brand no longer uses a module-level `unique symbol`, so a single TypeScript compilation that resolves the type from both the ESM and CJS outputs (which can happen under certain pnpm hoisting layouts) no longer sees two structurally-incompatible variants of the same type.
The CLI MCP server's agent-chat tools (`start_agent_chat`, `send_agent_message`, `close_agent_chat`) now run on the new Sessions primitive, so AI assistants driving a `chat.agent` get the same idempotent-by-`chatId`, durable-across-runs behavior the browser transport gets. Required PAT scopes go from `write:inputStreams` to `read:sessions` + `write:sessions`.
The MCP server no longer tells the AI agent to wait for a run to complete after every `trigger_task` call. Waiting is now opt-in: the agent only waits when you ask it to (for example "trigger and then wait for it to finish"). This avoids burning tokens polling runs you didn't need to block on and keeps responses clearer.
Unit-test `chat.agent` definitions offline with `mockChatAgent` from `@trigger.dev/sdk/ai/test`. Drives a real agent's turn loop in-process — no network, no task runtime — so you can send messages, actions, and stop signals via driver methods, inspect captured output chunks, and verify hooks fire. Pairs with `MockLanguageModelV3` from `ai/test` for model mocking. `setupLocals` lets you pre-seed `locals` (DB clients, service stubs) before `run()` starts.
The broader `runInMockTaskContext` harness it's built on lives at `@trigger.dev/core/v3/test` — useful for unit-testing any task code, not just chat.
Pipeline the per-entry `HGETALL` fetches in `MollifierBuffer.listEntriesForEnv`. The previous serial implementation issued one Redis round-trip per runId returned by `LRANGE`, which dominated stale-sweep wall-time at any meaningful backlog (at the sweep's default maxCount=1000, this is ~1000 RTTs per env per pass). Behaviour is unchanged — entries are still skipped when the entry hash has been torn down by a concurrent drainer ack/fail between the LRANGE and the HGETALL.
Make mollifier buffer and drainer internals configurable. `MollifierBuffer` now accepts `ackGraceTtlSeconds`, `maxRetriesPerRequest`, `reconnectStepMs`, and `reconnectMaxMs` options, and `MollifierDrainer` accepts `maxBackoffMs` and `backoffFloorMs`. All default to their previous hardcoded values, so existing behaviour is unchanged.
`MollifierDrainer` accepts a `drainBatchSize` option (default 1) that controls how many entries are popped per env per tick — in-flight handlers remain capped by the global `concurrency`. `MollifierBuffer` also gains `getDrainingCount()` / `listStaleDraining()`, backed by a new `mollifier:draining` ZSET maintained atomically with pop/ack/fail/requeue (observability-only).
Add MollifierBuffer and MollifierDrainer primitives for trigger burst smoothing.
MollifierBuffer (`accept`, `pop`, `ack`, `requeue`, `fail`, `evaluateTrip`) is a per-env FIFO over Redis with atomic Lua transitions for status tracking. `evaluateTrip` is a sliding-window trip evaluator the webapp gate uses to detect per-env trigger bursts.
MollifierDrainer pops entries through a polling loop with a user-supplied handler. The loop survives transient Redis errors via capped exponential backoff (up to 5s), and per-env pop failures don't poison the rest of the batch — one env's blip is logged and counted as failed for that tick. Rotation is two-level: orgs at the top, envs within each org. The buffer maintains `mollifier:orgs` and `mollifier:org-envs:${orgId}` atomically with per-env queues, so the drainer walks orgs → envs directly without an in-memory cache. The `maxOrgsPerTick` option (default 500) caps how many orgs are scheduled per tick; for each picked org, one env is popped (rotating round-robin within the org). An org with N envs gets the same per-tick scheduling slot as an org with 1 env, so tenant-level drainage throughput is determined by org count rather than env count.
Mollifier `mutateSnapshot` now enforces a tag cap: an `append_tags` patch carrying `maxTags` returns `"limit_exceeded"` (writing nothing) when the deduped tag count would exceed the limit, so a buffered run can't accumulate more tags via the tags API than the trigger validator allows at creation.
Update the bundled OpenTelemetry packages to their latest releases (`@opentelemetry/sdk-node` 0.218.0, `@opentelemetry/core` 2.7.1, `@opentelemetry/host-metrics` 0.38.3).
Add `GetProjectEnvironmentsResponseBody` and `ProjectEnvironment` schemas for the new `GET /api/v1/projects/{projectRef}/environments` endpoint, which lists the parent environments (dev, staging, preview, prod) a personal access token can access for a project. Dev is scoped to the token owner and branch (preview child) environments are excluded.
Fix `COULD_NOT_FIND_EXECUTOR` when a task's definition is loaded via `await import(...)` from inside another task's `run()`. The runtime workers now register such tasks with a sentinel file context, and the catalog logs a one-time warning per task id.
Retry `TASK_MIDDLEWARE_ERROR` under the task's retry policy instead of failing the run on the first attempt. The error was already classified as retryable by `shouldRetryError`, but `shouldLookupRetrySettings` did not include it, so the retry flow fell through to `fail_run`. Fixes #3231.
Retry `TASK_PROCESS_SIGSEGV` task crashes under the user's retry policy instead of failing the run on the first segfault. SIGSEGV in Node tasks is frequently non-deterministic (native addon races, JIT/GC interaction, near-OOM in native code, host issues), so retrying on a fresh process often succeeds. The retry is gated by the task's existing `retry` config + `maxAttempts` — same path `TASK_PROCESS_SIGTERM` and uncaught exceptions already use — so tasks without a retry policy still fail fast.
Add `region` to the runs list / retrieve API: filter runs by region (`runs.list({ region: "..." })` / `filter[region]=<masterQueue>`) and read each run's executing region from the new `region` field on the response.
Bump `@s2-dev/streamstore` to `0.22.10` to fix a `TASK_RUN_UNCAUGHT_EXCEPTION` ("Invalid state: Unable to enqueue") when a `chat.agent` turn is aborted mid-stream.
Add `SessionId` friendly ID generator and schemas for the new durable Session primitive. Exported from `@trigger.dev/core/v3/isomorphic` alongside `RunId`, `BatchId`, etc. Ships the `CreateSessionStreamWaitpoint` request/response schemas alongside the main Session CRUD.
**Sessions** — a durable, run-aware stream channel keyed on a stable `externalId`. A Session is the unit of state that owns a multi-run conversation: messages flow through `.in`, responses through `.out`, both survive run boundaries. Sessions back the new `chat.agent` runtime, and you can build on them directly for any pattern that needs durable bi-directional streaming across runs.
```ts
import{sessions,tasks}from"@trigger.dev/sdk";
// Trigger a task and subscribe to its session output in one call
See [/docs/ai-chat/overview](https://trigger.dev/docs/ai-chat/overview) for the full surface — Sessions powers the durable, resumable chat runtime described there.
Add `TriggerClient` for running multiple SDK clients side-by-side, each with its own auth, preview branch, and baseURL. Useful when a single process needs to trigger tasks or read runs across multiple projects, environments, or preview branches without mutating shared global state.
`trigger skills` installs Trigger.dev agent skills into your coding agent so it knows how to write tasks, schedules, realtime, and chat.agent code. The skills ship with the CLI and are copied into each tool's native skills directory (Claude Code, Cursor, GitHub Copilot, and Codex / AGENTS.md), and `trigger dev` offers to install them on first run.
```bash
trigger skills --target claude-code
```
Replaces the previous `install-rules` command, which stays as an alias.
Truncate large error stacks and messages to prevent OOM crashes. Stack traces are capped at 50 frames (keeping top 5 + bottom 45 with an omission notice), individual stack lines at 1024 chars, and error messages at 1000 chars. Applied in parseError, sanitizeError, and OTel span recording.
Fix `TypeError` in `unflattenAttributes` when the input attribute map contains conflicting dotted key paths (e.g. both `a.b` set to a scalar and `a.b.c` set to a value). The path-walk loop now applies last-write-wins when a prior key wrote a primitive, null, or array at an intermediate slot, matching the existing precedent in `AttributeFlattener.addAttribute`. Callers no longer crash when handed malformed external attribute inputs.
Fix external trace context leaking across runs on warm-started workers with `processKeepAlive` enabled. Every subsequent run's attempt span was being exported with the first run's `traceId` and `parentSpanId`, breaking causal-chain navigation in external APM tools. Runs without an external trace context are unaffected.
Repo-specific signal for anyone (human or agent) reviewing a PR in this codebase. Calibrates what counts as critical, what to always check, and what to skip.
## What makes a 🔴 Important finding here
Reserve 🔴 for things that would page someone or block a rollback. In this codebase, that means:
- **Rolling-deploy breakage.** Old and new versions of the webapp/supervisor run side-by-side during deploys. A change is broken if:
- A Lua script's behavior changes for a given key set without versioning (rename the script with a behavior-descriptive suffix like `Tracked` rather than `V2` — both versions must coexist safely).
- A Redis data shape used by both versions changes in place. New shapes need a new key namespace.
- A migration is not backward-compatible with the prior image.
- **Schema / migration safety.** Prisma migrations must be backward-compatible with the prior deploy. Adding NOT NULL without a default, dropping a column an old image still reads, renaming a column — all 🔴.
- **ClickHouse migration ordering + idempotency.** Goose runs in strict mode in the deploy pipeline and refuses to apply a missing version below the current version — slotting a new file in below the latest already-applied version blocks the deploy. New ClickHouse migration files MUST use the next available number (`max(files in internal-packages/clickhouse/schema/) + 1`); if main has added migrations while you've been on a branch, renumber yours. DDL must also be idempotent (`ADD COLUMN IF NOT EXISTS`, `DROP COLUMN IF EXISTS`, `CREATE TABLE IF NOT EXISTS`, `ADD INDEX IF NOT EXISTS`) so a partial / `--allow-missing` apply elsewhere doesn't fail on retry. Either fault is 🔴 — both break test/prod deploys. Rules live in `internal-packages/clickhouse/CLAUDE.md`.
- **Queue / concurrency correctness.** RunQueue, MarQS (V1, legacy), redis-worker — any change to enqueue / dequeue / locking semantics. Re-derive the invariant on paper before flagging or accepting.
- **Missing index on a hot table.** New Prisma queries against `TaskRun`, `TaskRunExecutionSnapshot`, `JobRun`, `Project`, etc. must use an existing index. Check `internal-packages/database/prisma/schema.prisma` for the relevant `@@index` lines — don't guess and don't propose `EXPLAIN`.
- **Recovery-path queries.** Any `TaskRun.findFirst` / `findMany` added to a schedule, run-recovery, or restart loop. Recovery fan-outs (Redis crash, restart storms) turn "rare indexed query" into a DB incident. 🔴 even if indexed.
- **Aggregations on hot tables.** No `COUNT` / `GROUP BY` on `TaskRun` or other multi-million-row tables. Use Redis or ClickHouse for counts.
- **Prod Redis blast-radius.** New code paths that `SCAN` with broad patterns (`*foo*`) on prod-shaped Redis, or `EVAL` Lua with `SCAN` loops inside. Both are 🔴.
- **`@trigger.dev/core` direct import** from anywhere outside the SDK package. Always import from `@trigger.dev/sdk`. Core direct imports are 🔴 — they break the public API contract.
- **Heavy execute-deps imported into request-handler bundles.** Specifically `chat.handover` and similar split-bundle entry points must not transitively import the agent task's execute path. Watch for new imports added at module top-level of route files.
- **V1 engine code modified in a "V2 only" PR.** The `apps/webapp/app/v3/` directory contains both. If the PR description says V2-only but it touches `triggerTaskV1`, `cancelTaskRunV1`, `MarQS`, etc. — 🔴.
## Always check
- **Tests use testcontainers, not mocks.** Vitest with `redisTest` / `postgresTest` / `containerTest` from `@internal/testcontainers`. Any new `vi.mock(...)` on Redis, Postgres, BullMQ, or other infra is wrong here — 🔴 if added in production-path tests, 🟡 if isolated unit test.
- **Public-package changes have a changeset.** `pnpm run changeset:add` produces `.changeset/*.md`. Required for any edit under `packages/*`. Missing → 🟡; missing on a breaking change → 🔴.
- **Server-only changes have `.server-changes/*.md`.** Required for `apps/webapp/`, `apps/supervisor/` edits with no public-package change. Body should be 1-2 sentences (it has to fit as one bullet in a future changelog). Missing → 🟡.
- **Lua script naming.** Coexisting scripts use behavior-descriptive suffixes (`Tracked`), never `V2`. Old name must keep working until the next deploy clears it.
- **RunQueue payload shape.** V2 run-queue payload's `projectId` is consumed by `workerQueueResolver` for override matching. If a PR drops it from the payload, 🔴.
- **`safeSend` scope.** Defensive IPC wrappers belong on loop / interval / handler contexts, not one-shot terminal sends. If the PR adds `safeSend` to a single terminal call for consistency, 🟡 with a "remove this" suggestion.
- **Zod version.** Pinned to `3.25.76` monorepo-wide. New package adding zod with a different version or range — 🔴.
## Skip (do NOT flag)
- Anything Prettier / ESLint catches. CI runs both.
- TypeScript style preferences (`type` vs `interface`) — already covered by repo standards.
- Test coverage exhortations as a generic suggestion. Only flag missing tests when a specific code path is genuinely untested and the path has prior incidents.
-`agentcrumbs` markers (`// @crumbs`, `// #region @crumbs`) and `agentcrumbs` imports — these are temporary debug instrumentation stripped before merge.
-`// removed comments for removed code`, renamed `_unused` vars, re-exported types as "backwards compatibility shims" — also covered by repo standards.
- Suggestions to "add error handling" without naming a specific scenario that breaks.
The `apps/webapp/app/v3/` directory name is misleading — most code there is V2. Only specific files are V1-only legacy: `MarQS` queue, `triggerTaskV1`, `cancelTaskRunV1`, and a handful of others (see `apps/webapp/CLAUDE.md` for the exact list). Don't flag "you should refactor this to use V2" on those — they're frozen.
## Confidence calibration for this repo
The most common false-positive pattern: speculating about race conditions in code paths the agent doesn't have runtime visibility into. If the only evidence is "this *could* race", drop it. If you can point to a specific interleaving with file:line for each step, surface it.
When adding a new dependency to any package.json in the monorepo:
1.**Look up the latest version** on npm before adding:
```bash
pnpm view <package-name> version
```
If unsure which version to use (e.g. major version compatibility), confirm with the user.
2. **Edit the package.json directly** — do NOT use `pnpm add` as it can cause issues in the monorepo. Add the dependency with the correct version range (typically `^x.y.z`).
3. **Run `pnpm i` from the repo root** after editing to install and update the lockfile:
```bash
pnpm i
```
Always run from the repo root, not from the package directory.

You are auditing this PR for drift against `.claude/REVIEW.md`.
## Context
`.claude/REVIEW.md` is the repo's source of truth for what AI / agent code reviewers should treat as critical findings (rolling-deploy safety, hot-table indexes, recovery-path queries, testcontainers usage, Lua versioning, etc.). It is consumed by review agents to calibrate severity. If REVIEW.md goes stale, every future agent review degrades.
## Strategy — read this first
You have a hard turn budget. Spend it on signal, not coverage. The audit is allowed to miss things; it is NOT allowed to time out.
1. Read `.claude/REVIEW.md` once, in full.
2. Run `git diff origin/main...HEAD --name-only` to get the list of changed files. Do NOT read the diff content yet.
3. Scan the file-list for relevance to REVIEW.md scope. Relevance signals: changes to Prisma schema, Redis / queue / Lua code, hot tables, recovery / restart loops, new packages, deletions of paths REVIEW.md cites. Skim everything else.
4. Open at most **5 files** total — only the ones most likely to surface a real signal. If nothing in the file-list looks relevant to any REVIEW.md rule, do NOT read any files; go straight to the verdict.
5. Form a verdict and stop. Do not exhaust the turn budget exploring.
Large PRs (>50 files changed) are a strong signal to be MORE selective, not more thorough. Pick 3-5 files at most.
## What to look for
- **Stale references** — does any REVIEW.md rule cite a file, directory, function, table, Prisma model, or package name that has been removed or renamed in this PR (or is already gone from `main`)?
- **Contradictions** — does code in this PR clearly violate a current REVIEW.md rule? (Don't re-review the PR. Only flag if REVIEW.md and the PR plainly disagree.)
- **Missing rules** — does this PR introduce a new pattern future reviewers should know about? Examples: a new hot table, a new Lua-script versioning convention, a new safety wrapper, a new "must always check" invariant.
- **Obsolete rules** — has the repo moved past a constraint REVIEW.md still asserts? (e.g. a deprecated path is gone, a pattern is now linted, V1 code is deleted.)
## Response format
If nothing needs changing:
✅ REVIEW.md looks current for this PR.
Otherwise:
📝 **REVIEW.md updates suggested:**
- **[stale]** `<rule excerpt>` — <what's stale and why>
- **[contradiction]** `<rule excerpt>` — <what in this PR disagrees>
- **[missing]** under `## <section>` — <one-sentence draft rule>
- **[obsolete]** `<rule excerpt>` — <why this rule no longer applies>
## Rules
- Maximum 3 suggestions per audit. Pick the highest-signal ones.
- Only flag things that would actually mislead a future reviewer. Style and wording do not count.
- Do NOT review the PR itself. Do NOT propose rules outside REVIEW.md's existing sections.
- Do NOT propose rules for one-off PR specifics that don't generalize to future PRs.
- If REVIEW.md does not exist in the repo, respond with `(skip)` and stop.
- When in doubt between "one more file read" and "finish now" — finish now.

The body text (below the frontmatter) is a one-line description of the change. Keep it concise — it will appear in release notes.
### Writing guidance
These entries are public-facing - they ship verbatim in user-visible release notes. A few rules to keep them clean:
- **One sentence is usually enough.** The body is the bullet in the changelog. If you need a paragraph, you're probably describing the implementation rather than the change.
- **Describe behavior, not implementation.** Skip internal scopes, middleware names, library specifics, framework internals. Users care about what's different for them, not how it's wired.
- **Never name internal tools or infra.** Observability stacks, internal services, infra components, monitoring backends, CI surfaces, AWS specifics - none of these belong in user-facing notes.
## Lifecycle
1. Engineer adds a `.server-changes/` file in their PR
Add a "Back office" tab to `/admin` and a per-organization detail page at `/admin/back-office/orgs/:orgId`. The first action available on that page is editing the org's API rate limit: admins can save a `tokenBucket` override (refill rate, interval, max tokens) and see a plain-English preview of the resulting sustained rate and burst allowance. Writes are audit-logged via the server logger.
Admin worker groups API: add GET loader and expose more fields on POST.
