github-actions[bot] d825427cbc chore: release v4.4.5 (#3406)
## 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.

Matt Aitken 7c7d785552 Don't log waitpoint output when resolving (#3490)
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

nicktrn e2b9e0f9f5 feat(cli-v3): add --no-browser flag and examples to init/login --help (#3483)
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.

Eric Allam c69e939c34 feat: Sessions - bidirectional durable agent streams (#3417)
> ⚠️ **Not released yet.** This PR is the server-side foundation only.
The SDK changes that customers will actually use (`chat.agent`
migration, `chat.createStartSessionAction`, `useTriggerChatTransport`
updates) live on a separate branch and ship together in an upcoming
`@trigger.dev/sdk` prerelease. Until that prerelease is published, this
surface is reachable only via direct HTTP.

## What this gives Trigger.dev users

A new first-class primitive, **Session**, for durable, task-bound,
bidirectional I/O that outlives any single run. Sessions are the run
manager for `chat.agent` going forward, and they unblock anything else
that needs "one identifier, many runs over time" with a stable channel
pair the client can write to and subscribe to.

### Use cases unblocked

- **Chat agents that persist across many runs.** One session per chat
(keyed on your own `chatId` via `externalId`), turns 1..N attach to the
same Session, the UI subscribes once and keeps receiving output as new
runs take over.
- **Approval loops and long-running tasks with user feedback.** The task
waits on `.in`, the client writes to `.in`, the server enforces
no-writes-after-close.
- **Workflow progress streams that live past the run.** Subscribe to
`.out` after the task finishes to replay history.
- **Resume-next-day flows.** A session is a durable row, not a transient
stream. Send a message a day later and the server triggers a fresh run
on the same session.

### How it works (Session-as-run-manager)

A Session row is task-bound (`taskIdentifier` + `triggerConfig` are
required) and owns its current run via `currentRunId` +
`currentRunVersion` for optimistic claim. Three trigger paths:

1. **Session create** — `POST /api/v1/sessions` creates the row and
triggers the first run synchronously.
2. **Append-time probe** — `POST
/realtime/v1/sessions/:session/in/append` checks if the current run is
alive; if it has terminated (idle exit, crash, etc.), the server
triggers a new run before processing the append.
3. **End-and-continue handoff** — `POST
/api/v1/sessions/:session/end-and-continue`, called by the running
agent, triggers a fresh run and atomically swaps `currentRunId`. Used by
`chat.requestUpgrade()` for version handoffs.

Every triggered run is recorded in the `SessionRun` audit table with a
reason (`initial`, `continuation`, `upgrade`, `manual`).

## Public API surface

### Control plane

- `POST /api/v1/sessions` — create. Idempotent on `(env, externalId)`.
Triggers the first run, returns the session and a session-scoped public
access token. Returns 409 if the upserted row is already closed.
- `GET /api/v1/sessions/:session` — retrieve by friendlyId
(`session_abc...`) or by your own externalId (server disambiguates by
prefix).
- `GET /api/v1/sessions` — list with filters (`type`, `tag`,
`taskIdentifier`, `externalId`, derived `status` ACTIVE/CLOSED/EXPIRED,
created-at range) and cursor pagination. Backed by ClickHouse.
- `PATCH /api/v1/sessions/:session` — update tags / metadata /
externalId.
- `POST /api/v1/sessions/:session/close` — terminate. Idempotent,
hard-blocks new server-brokered writes.
- `POST /api/v1/sessions/:session/end-and-continue` — agent-only handoff
to a fresh run.

### Realtime

- `PUT /realtime/v1/sessions/:session/:io` — initialize a channel.
Returns S2 credentials in headers so high-throughput clients can write
direct to S2.
- `GET /realtime/v1/sessions/:session/:io` — SSE subscribe. Supports
Last-Event-ID resume and an opt-in `X-Peek-Settled: 1` header that
fast-closes the stream when the upstream is already settled
(`trigger:turn-complete`), eliminating long-poll wait on
reconnect-on-reload paths.
- `POST /realtime/v1/sessions/:session/:io/append` — server-side
appends.
- `POST /api/v1/runs/:runFriendlyId/session-streams/wait` — runs wait on
a session stream as a waitpoint, with a race-check to avoid suspending
if data already landed.

### Auth scopes

`sessions` is a new resource type. `read:sessions:{id}`,
`write:sessions:{id}`, `admin:sessions:{id}` flow through the existing
JWT validator. Session-scoped public access tokens minted by the server
replace browser-held trigger-task tokens for chat-style flows — the
browser never sees a run identifier or a run-scoped token in steady
state.

## What's coming after this PR

- **SDK + chat.agent migration**: separate branch, separate PR, ships in
the next `@trigger.dev/sdk` prerelease alongside this server deploy.
Customers using the prerelease `chat.agent` will follow the [upgrade
guide](https://github.com/triggerdotdev/trigger.dev/blob/docs/tri-7532-ai-sdk-chat-transport-and-chat-task-system/docs/ai-chat/upgrade-guide.mdx).
- **Dashboard surfaces**: dedicated agent list, agent playground, agent
view on the run dashboard. Tracking separately.

## Implementation notes

- **Postgres `Session` table**: scalar scoping columns (`projectId`,
`runtimeEnvironmentId`, `environmentType`, `organizationId`) without
FKs, matching the January TaskRun FK-removal decision. Point-lookup
indexes only — list queries go to ClickHouse. Terminal markers
(`closedAt`, `expiresAt`) are write-once.
- **ClickHouse `sessions_v1`**: ReplacingMergeTree, partitioned by
month, ordered by `(org_id, project_id, environment_id, created_at,
session_id)`. Tags indexed via `tokenbf_v1` skip index.
- **`SessionsReplicationService`**: mirrors `RunsReplicationService`
exactly — leader-locked logical replication consumer,
`ConcurrentFlushScheduler`, retry with exponential backoff + jitter,
identical metric shape. Dedicated slot + publication so the two consume
independently.
- **S2 keys**: `sessions/{addressingKey}/{out|in}`. The existing
`runs/{runId}/{streamId}` key format for run-scoped streams is
untouched.
- **Optimistic claim**: `ensureRunForSession` triggers a run upfront
(cheap to cancel if it loses the race), then attempts an `updateMany`
keyed on `currentRunVersion`. Loser cancels its triggered run and reuses
the winner's. No DB lock held across the trigger.

### What did NOT change

Run-scoped `streams.pipe` / `streams.input` and the existing
`/realtime/v1/streams/{runId}/...` routes are unchanged. Sessions are
net-new — not a reshaping of the current streams API.

## Deploy notes

- Set `SESSION_REPLICATION_CLICKHOUSE_URL` and
`SESSION_REPLICATION_ENABLED=1` to enable the replication consumer.
- The `Session` table needs `REPLICA IDENTITY FULL` set on the prod
source DB before the publication is created (same one-time DDL we did
for `TaskRun`). Required for delete events to carry full column values.
- Cross-form authorization on the `GET /api/v1/sessions/:session` loader
(a JWT minted for either form authorizes both URL forms). Action routes
are URL-form-specific, matching how the SDK mints PATs.

## Verification

- Webapp typecheck clean (10/10).
- `apps/webapp/test/sessionsReplicationService.test.ts` — round-trip
tests for insert/update/delete through Postgres logical replication into
ClickHouse via testcontainers.
- Live end-to-end against local dev: create + retrieve (both forms) +
update + close, `.out.initialize` + `.out.append` x2 + `.in.send` +
`.out.subscribe` over SSE, list with all filter combinations +
pagination, `end-and-continue` swap, `X-Peek-Settled` fast-close
(verified in browser via reconnect-on-reload and via curl). Replicated
row lands in ClickHouse within ~1s.
- Multi-round Devin + CodeRabbit review feedback addressed
(read-after-write paths use `prisma` writer, info-leak on auth-routes
masked as 403, peek-settled discriminator parsing fix, etc.).

## Test plan

- [ ] `pnpm run typecheck --filter webapp`
- [ ] `pnpm run test --filter webapp
./test/sessionsReplicationService.test.ts --run`
- [ ] Start the webapp with `SESSION_REPLICATION_CLICKHOUSE_URL` and
`SESSION_REPLICATION_ENABLED=1`. Confirm the slot and publication
auto-create on boot.

devin-ai-integration[bot] 4b28080ed4 feat: add isReplay to run context (#3454)
## Summary

Adds `isReplay` boolean to the run context (`ctx.run.isReplay`),
following the same pattern as the existing `isTest`. The value is
derived from the existing `replayedFromTaskRunFriendlyId` database
field, so no schema migration is needed.

##  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

- Verified `@trigger.dev/core` builds successfully
- Verified `webapp` typechecks successfully
- All new fields use `default(false)` for backwards compatibility

---

## Changelog

- Added `isReplay` to `TaskRun` and `V3TaskRun` schemas in `common.ts`
- Added `RUN_IS_REPLAY` semantic attribute and wired it in `taskContext`
- Propagated `isReplay` through the dequeue system, run attempt system,
and all execution context construction paths (V1 + V2)
- Added `isReplay` to `DequeuedMessage` and
`TaskRunExecutionLazyAttemptPayload` schemas
- Added patch changeset for `@trigger.dev/core`
- Updated docs: added `isReplay` to context reference, added "Detecting
replays" section to replaying page

Eric Allam 69acdc2b32 fix(core): truncate large error stacks and messages to prevent OOM (#3405)
## Summary

Large error stacks and messages can OOM the worker process when
serialized into OTel spans or `TaskRunError` objects. This was reported
when throwing an error with a massive `.stack` property from a chat
agent hook.

This adds frame-based stack truncation (similar to Sentry's approach)
plus message length limits, applied consistently across all error
serialization paths.

### What changed

**`packages/core/src/v3/errors.ts`**
- `truncateStack()` — parses `error.stack` into message lines + frame
lines, caps at 50 frames (keep top 5 closest to throw + bottom 45 entry
points, with "... N frames omitted ..." in between). Individual lines
capped at 1024 chars.
- `truncateMessage()` — caps error messages at 1000 chars
- Applied in `parseError()` and `sanitizeError()`

**`packages/core/src/v3/otel/utils.ts`**
- `sanitizeSpanError()` now uses `truncateStack` and `truncateMessage`
from `errors.ts` instead of duplicating truncation logic
- Non-Error values (strings, JSON) capped at 5000 chars

**`packages/core/src/v3/tracer.ts`**
- `startActiveSpan` catch block now delegates to `recordSpanException()`
instead of calling `span.recordException()` directly

### Limits

| What | Limit | Rationale |
|------|-------|-----------|
| Stack frames | 50 | Matches Sentry's `STACKTRACE_FRAME_LIMIT` |
| Top frames kept | 5 | Closest to throw site |
| Bottom frames kept | 45 | Entry points / framework frames |
| Per-line length | 1024 | Matches Sentry, prevents regex DoS |
| Message length | 1000 | Bounded but generous |
| Generic string (non-Error) | 5000 | Fallback for JSON/string errors in
spans |

## Test plan

- [x] 17 unit tests in `packages/core/test/errors.test.ts`
- [x] E2E: threw a 300-frame / 5000-char-message error in the ai-chat
reference app, verified truncated stack and message in span via
`get_span_details`
- [x] Verified the run survived the error (no OOM, continued waiting for
next message)

## Summary
12 new features, 59 improvements, 17 bug fixes.

## Highlights

- Add support for setting TTL (time-to-live) defaults at the task level
and globally in trigger.config.ts, with per-trigger overrides still
taking precedence
([#3196](https://github.com/triggerdotdev/trigger.dev/pull/3196))
- Large run outputs can use the new API which allows switching object
storage providers.
([#3275](https://github.com/triggerdotdev/trigger.dev/pull/3275))

## Improvements
- Add platform notifications support to the CLI. The `trigger dev` and
`trigger login` commands now fetch and display platform notifications
(info, warn, error, success) from the server. Includes discovery-based
filtering to conditionally show notifications based on project file
patterns, color markup rendering for styled terminal output, and a
non-blocking display flow with a spinner fallback for slow fetches. Use
`--skip-platform-notifications` flag with `trigger dev` to disable the
notification check.
([#3254](https://github.com/triggerdotdev/trigger.dev/pull/3254))
- Add `get_span_details` MCP tool for inspecting individual spans within
a run trace.
([#3255](https://github.com/triggerdotdev/trigger.dev/pull/3255))
- New `get_span_details` tool returns full span attributes, timing,
events, and AI enrichment (model, tokens, cost, speed)
- Span IDs now shown in `get_run_details` trace output for easy
discovery
- New API endpoint `GET /api/v1/runs/:runId/spans/:spanId`
- New `retrieveSpan()` method on the API client
- `get_query_schema` — discover available TRQL tables and columns
- `query` — execute TRQL queries against your data
- `list_dashboards` — list built-in dashboards and their widgets
- `run_dashboard_query` — execute a single dashboard widget query
- `whoami` — show current profile, user, and API URL
- `list_profiles` — list all configured CLI profiles
- `switch_profile` — switch active profile for the MCP session
- `start_dev_server` — start `trigger dev` in the background and stream
output
- `stop_dev_server` — stop the running dev server
- `dev_server_status` — check dev server status and view recent logs
- `GET /api/v1/query/schema` — query table schema discovery
- `GET /api/v1/query/dashboards` — list built-in dashboards
- `--readonly` flag hides write tools (`deploy`, `trigger_task`,
`cancel_run`) so the AI cannot make changes
- `read:query` JWT scope for query endpoint authorization
- `get_run_details` trace output is now paginated with cursor support
- MCP tool annotations (`readOnlyHint`, `destructiveHint`) for all tools
- `get_query_schema` now requires a table name and returns only one
table's schema (was returning all tables)
- `get_current_worker` no longer inlines payload schemas; use new
`get_task_schema` tool instead
- Query results formatted as text tables instead of JSON (~50% fewer
tokens)
- `cancel_run`, `list_deploys`, `list_preview_branches` formatted as
text instead of raw JSON
- Schema and dashboard API responses cached to avoid redundant fetches
- Adapted the CLI API client to propagate the trigger source via http
headers.
([#3241](https://github.com/triggerdotdev/trigger.dev/pull/3241))
- Propagate run tags to span attributes so they can be extracted
server-side for LLM cost attribution metadata.
([#3213](https://github.com/triggerdotdev/trigger.dev/pull/3213))
- New `get_span_details` tool returns full span attributes, timing,
events, and AI enrichment (model, tokens, cost, speed)

- Add optional `hasPrivateLink` field to the dequeue message
organization object for private networking support
([#3264](https://github.com/triggerdotdev/trigger.dev/pull/3264))
- Define and manage AI prompts with `prompts.define()`. Create typesafe
prompt templates with variables, resolve them at runtime, and manage
versions and overrides from the dashboard without redeploying.
([#3244](https://github.com/triggerdotdev/trigger.dev/pull/3244))

## Bug fixes
- Fix dev CLI leaking build directories on rebuild, causing disk space
accumulation. Deprecated workers are now pruned (capped at 2 retained)
when no active runs reference them. The watchdog process also cleans up
`.trigger/tmp/` when the dev CLI is killed ungracefully (e.g. SIGKILL
from pnpm).
([#3224](https://github.com/triggerdotdev/trigger.dev/pull/3224))
- Fix `--load` flag being silently ignored on local/self-hosted builds.
([#3114](https://github.com/triggerdotdev/trigger.dev/pull/3114))
- Fixed `search_docs` tool failing due to renamed upstream Mintlify tool
(`SearchTriggerDev` → `search_trigger_dev`)
- Fixed `list_deploys` failing when deployments have null
`runtime`/`runtimeVersion` fields (#3139)
- Fixed `list_preview_branches` crashing due to incorrect response shape
access
- Fixed `metrics` table column documented as `value` instead of
`metric_value` in query docs
- Fixed dev CLI leaking build directories on rebuild — deprecated
workers now clean up their build dirs when their last run completes
- Fixed `search_docs` tool failing due to renamed upstream Mintlify tool
(`SearchTriggerDev` → `search_trigger_dev`)
- Fixed `list_deploys` failing when deployments have null
`runtime`/`runtimeVersion` fields (#3139)
- Fixed `list_preview_branches` crashing due to incorrect response shape
access
- Fixed `metrics` table column documented as `value` instead of
`metric_value` in query docs
- Fixed dev CLI leaking build directories on rebuild — deprecated
workers now clean up their build dirs when their last run completes

## Server changes

These changes affect the self-hosted Docker image and Trigger.dev Cloud:

- Add admin UI for viewing and editing feature flags (org-level
overrides and global defaults).
([#3291](https://github.com/triggerdotdev/trigger.dev/pull/3291))
- AI prompt management dashboard and enhanced span inspectors.
  
  **Prompt management:**
- Prompts list page with version status, model, override indicators, and
24h usage sparklines
- Prompt detail page with template viewer, variable preview, version
history timeline, and override editor
- Create, edit, and remove overrides to change prompt content or model
without redeploying
  - Promote any code-deployed version to current
- Generations tab with infinite scroll, live polling, and inline span
inspector
- Per-prompt metrics: total generations, avg tokens, avg cost, latency,
with version-level breakdowns
  
  **AI span inspectors:**
- Custom inspectors for `ai.generateText`, `ai.streamText`,
`ai.generateObject`, `ai.streamObject` parent spans
- `ai.toolCall` inspector showing tool name, call ID, and input
arguments
  - `ai.embed` inspector showing model, provider, and input text
- Prompt tab on AI spans linking to prompt version with template and
input variables
  - Compact timestamp and duration header on all AI span inspectors
  
  **AI metrics dashboard:**
- Operations, Providers, and Prompts filters on the AI Metrics dashboard
  - Cost by prompt widget
  - "AI" section in the sidebar with Prompts and AI Metrics links
  
  **Other improvements:**
  - Resizable panel sizes now persist across page refreshes
- Fixed `<div>` inside `<p>` DOM nesting warnings in span titles and
chat messages
([#3244](https://github.com/triggerdotdev/trigger.dev/pull/3244))
- Add allowRollbacks query param to the promote deployment API to enable
version downgrades
([#3214](https://github.com/triggerdotdev/trigger.dev/pull/3214))
- Pre-warm compute templates on deploy for orgs with compute access.
Required for projects using a compute region, background-only for
others.
([#3114](https://github.com/triggerdotdev/trigger.dev/pull/3114))
- Add automatic LLM cost calculation for spans with GenAI semantic
conventions. When a span arrives with `gen_ai.response.model` and token
usage data, costs are calculated from an in-memory pricing registry
backed by Postgres and dual-written to both span attributes
(`trigger.llm.*`) and a new `llm_metrics_v1` ClickHouse table that
captures usage, cost, performance (TTFC, tokens/sec), and behavioral
(finish reason, operation type) metrics.
([#3213](https://github.com/triggerdotdev/trigger.dev/pull/3213))
- Add API endpoint `GET /api/v1/runs/:runId/spans/:spanId` that returns
detailed span information including properties, events, AI enrichment
(model, tokens, cost), and triggered child runs.
([#3255](https://github.com/triggerdotdev/trigger.dev/pull/3255))
- Multi-provider object storage with protocol-based routing for
zero-downtime migration
([#3275](https://github.com/triggerdotdev/trigger.dev/pull/3275))
- Add IAM role-based auth support for object stores (no access keys
required).
([#3275](https://github.com/triggerdotdev/trigger.dev/pull/3275))
- Add platform notifications to inform users about new features,
changelogs, and platform events directly in the dashboard.
([#3254](https://github.com/triggerdotdev/trigger.dev/pull/3254))
- Add private networking support via AWS PrivateLink. Includes
BillingClient methods for managing private connections, org settings UI
pages for connection management, and supervisor changes to apply
`privatelink` pod labels for CiliumNetworkPolicy matching.
([#3264](https://github.com/triggerdotdev/trigger.dev/pull/3264))
- Reduce run start latency by skipping the intermediate queue when
concurrency is available. This optimization is rolled out per-region and
enabled automatically for development environments.
([#3299](https://github.com/triggerdotdev/trigger.dev/pull/3299))
- Extended the search filter on the environment variables page to match
on environment type (production, staging, development, preview) and
branch name, not just variable name and value.
([#3302](https://github.com/triggerdotdev/trigger.dev/pull/3302))
- Set `application_name` on Prisma connections from SERVICE_NAME so DB
load can be attributed by service
([#3348](https://github.com/triggerdotdev/trigger.dev/pull/3348))
- Fix transient R2/object store upload failures during batchTrigger()
item streaming.
  
- Added p-retry (3 attempts, 500ms–2s exponential backoff) around
`uploadPacketToObjectStore` in `BatchPayloadProcessor.process()` so
transient network errors self-heal server-side rather than aborting the
entire batch stream.
- Removed `x-should-retry: false` from the 500 response on the batch
items route so the SDK's existing 5xx retry path can recover if
server-side retries are exhausted. Item deduplication by index makes
full-stream retries safe.
([#3331](https://github.com/triggerdotdev/trigger.dev/pull/3331))
- Concurrency-keyed queues now use a single master queue entry per base
queue instead of one entry per key. Prevents high-CK-count tenants from
consuming the entire parentQueueLimit window and starving other tenants
on the same shard.
([#3219](https://github.com/triggerdotdev/trigger.dev/pull/3219))
- Reduce lock contention when processing large `batchTriggerAndWait`
batches. Previously, each batch item acquired a Redis lock on the parent
run to insert a `TaskRunWaitpoint` row, causing
`LockAcquisitionTimeoutError` with high concurrency (880 errors/24h in
prod). Since `blockRunWithCreatedBatch` already transitions the parent
to `EXECUTING_WITH_WAITPOINTS` before items are processed, the per-item
lock is unnecessary. The new `blockRunWithWaitpointLockless` method
performs only the idempotent CTE insert without acquiring the lock.
([#3232](https://github.com/triggerdotdev/trigger.dev/pull/3232))
- Strip `secure` query parameter from QUERY_CLICKHOUSE_URL before
passing to ClickHouse client. This was already done for the main and
logs ClickHouse clients but was missing for the query client, causing a
startup crash with `Error: Unknown URL parameters: secure`.
([#3204](https://github.com/triggerdotdev/trigger.dev/pull/3204))
- Fix `OrganizationsPresenter.#getEnvironment` matching the wrong
development environment on teams with multiple members. All dev
environments share the slug `"dev"`, so the previous `find` by slug
alone could return another member's environment. Now filters DEVELOPMENT
environments by `orgMember.userId` to ensure the logged-in user's dev
environment is selected.
([#3273](https://github.com/triggerdotdev/trigger.dev/pull/3273))

Matt Aitken 68e88d0d71 Object Storage seamless migration (#3275)
This allows seamless migration to different object storage.

Existing runs that have offloaded payloads/outputs will continue to use
the default object store (configured using `OBJECT_STORE_*` env vars).

You can add additional stores by setting new env vars:
- `OBJECT_STORE_DEFAULT_PROTOCOL` this determines where new run large
payloads will get stored.
- If you set that you need to set new env vars for that protocol.
  
Example:

```
OBJECT_STORE_DEFAULT_PROTOCOL=“s3"
OBJECT_STORE_S3_BASE_URL=https://s3.us-east-1.amazonaws.com
OBJECT_STORE_S3_ACCESS_KEY_ID=<val>
OBJECT_STORE_S3_SECRET_ACCESS_KEY=<val>
OBJECT_STORE_S3_REGION=us-east-1
OBJECT_STORE_S3_SERVICE=s3
```

Saadi Myftija d4772b5f60 feat: run annotations (#3241)
Adds an `annotations` JSONB column to task runs that captures where and
how each run was triggered.
This enables filtering and analyzing trigger origins without querying up
the run tree. Also enables making scheduling decisions based on the
trigger source, e.g., use separate affinities for scheduled runs.

Each run records:
- **triggerSource**: who initiated it (sdk, api, dashboard, cli, mcp,
schedule)
- **triggerAction**: what kind of action (trigger, replay, test)
- **rootTriggerSource**: the trigger source of the root ancestor,
propagated through the entire run
 tree
- **rootScheduleId**: schedule id, in case the run tree was triggered
from a schedule

Currently the main motivation for annotations it to determine whether a
run is part of a schedule-originated tree without traversing ancestors.

### A couple of design considerations
- **Decoupled source from method**: triggerSource and triggerAction are
separate fields to avoid
combinatorial explosion (every new source × every new action)
- **Server-side first**: all annotation values are primarily determined
on the server, only a minor SDK change needed
- **Forward-compatible**: annotation fields use
`z.enum([...]).or(anyString)` so new values can be
added without breaking validation; we currently don't need an explicit
version field for annotations.

Note: `metadata` would have been a more fitting name for the db column,
as it is consistent with other tables where we store this type of
information. It is already in use to store user metadata though, so we
go with `annotations` instead.

Eric Allam 54d95ee4b9 feat: AI prompt management dashboard and enhanced span inspectors (#3244)
- Full prompt management UI: list, detail, override, and version
management for AI prompts defined with `prompts.define()`
- Rich AI span inspectors for all AI SDK operations with token usage,
messages, and prompt context
- Real-time generation tracking with live polling and filtering

## Prompt management

Define prompts in your code with `prompts.define()`, then manage
versions and overrides from the dashboard without redeploying:

```typescript
import { task, prompts } from "@trigger.dev/sdk";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";
import { z } from "zod";

const supportPrompt = prompts.define({
  id: "customer-support",
  model: "gpt-4o",
  variables: z.object({
    customerName: z.string(),
    plan: z.string(),
    issue: z.string(),
  }),
  content: `You are a support agent for Acme SaaS.
Customer: {{customerName}} ({{plan}} plan)
Issue: {{issue}}
Respond with empathy and precision.`,
});

export const supportTask = task({
  id: "handle-support",
  run: async (payload) => {
    const resolved = await supportPrompt.resolve({
      customerName: payload.name,
      plan: payload.plan,
      issue: payload.issue,
    });

    const result = await generateText({
      model: openai(resolved.model ?? "gpt-4o"),
      system: resolved.text,
      prompt: payload.issue,
      ...resolved.toAISDKTelemetry(),
    });

    return { response: result.text };
  },
});
```

The prompts list page shows each prompt with its current version, model,
override status, and a usage sparkline over the last 24 hours.

From the prompt detail page you can:

- **Create overrides** to change the prompt template or model without
redeploying. Overrides take priority over the deployed version when
`prompt.resolve()` is called.
- **Promote** any code-deployed version to be the current version
- **Browse generations** across all versions with infinite scroll and
live polling for new results
- **Filter** by version, model, operation type, and provider
- **View metrics** (total generations, avg tokens, avg cost, latency)
broken down by version

## AI span inspectors

Every AI SDK operation now gets a custom inspector in the run trace
view:

- **`ai.generateText` / `ai.streamText`** — Shows model, token usage,
cost, the full message thread (system prompt, user message, assistant
response), and linked prompt details
- **`ai.generateObject` / `ai.streamObject`** — Same as above plus the
JSON schema and structured output
- **`ai.toolCall`** — Shows tool name, call ID, and input arguments
- **`ai.embed`** — Shows model and the text being embedded

For generation spans linked to a prompt, a "Prompt" tab shows the prompt
metadata, the input variables passed to `resolve()`, and the template
content from the prompt version.

All AI span inspectors include a compact timestamp and duration header.

## Other improvements

- Resizable panel sizes now persist across page refreshes (patched
`@window-splitter/state` to fix snapshot restoration)
- Run page panels also persist their sizes
- Fixed `<div>` inside `<p>` DOM nesting warnings in span titles and
chat messages
- Added Operations and Providers filters to the AI metrics dashboard

Eric Allam 1cfc296c6b feat(ai): LLM metrics tracking and AI span inspector (#3213)
- Automatic LLM cost enrichment for AI SDK spans (streamText,
generateText, generateObject) or any other spans that use semantic
gen_ai attributes with support for 145+ models
- New AI span inspector sidebar showing model, tokens, cost, messages,
tool calls, and response text
- LLM metrics dual-write to ClickHouse `llm_metrics_v1` table for
analytics
- LLM metrics built-in dashboard (unlinked at the moment)
- Provider cost fallback — uses gateway/OpenRouter reported costs from
`providerMetadata` when registry pricing is unavailable
- Prefix-stripping for gateway/OpenRouter model names (e.g.
`mistral/mistral-large-3` matches `mistral-large-3` pricing)
- Admin dashboard for managing LLM model pricing (list, create, edit,
delete, search, test pattern matching)
- Missing models detection page — queries ClickHouse for unpriced models
with sample spans and Claude Code-ready prompts for adding pricing
- AI span seed script (`pnpm run db:seed:ai-spans`) with 51 spans across
12 provider systems for local dev testing
- UI fixes: `completionTokens`/`promptTokens` aliases,
`ai.response.object` display for generateObject, cache read/write token
breakdown

Eric Allam dbbe9f77f9 feat(cli): Expand and improve the MCP server and dev CLI command (#3224)
## Summary

Major expansion of the MCP server (14 → 25 tools), context efficiency
optimizations, new API endpoints, and a fix for the dev CLI leaking
build directories on disk.

### New MCP tools

- **Query & analytics**: `get_query_schema`, `query`, `list_dashboards`,
`run_dashboard_query` — query your data using TRQL directly from AI
assistants
- **Profile management**: `whoami`, `list_profiles`, `switch_profile` —
see and switch CLI profiles per-project (persisted to
`.trigger/mcp.json`)
- **Dev server control**: `start_dev_server`, `stop_dev_server`,
`dev_server_status` — start/stop `trigger dev` and stream build output
- **Task introspection**: `get_task_schema` — get payload schema for a
specific task (split out from `get_current_worker` to reduce context)

### New API endpoints

- `GET /api/v1/query/schema` — discover TRQL tables and columns
(server-driven, multi-table)
- `GET /api/v1/query/dashboards` — list built-in dashboard widgets and
their queries

### New features

- **`--readonly` flag** — hides write tools (`deploy`, `trigger_task`,
`cancel_run`) so agents can't make changes
- **`read:query` JWT scope** — new authorization scope for query
endpoints, with per-table granularity (`read:query:runs`,
`read:query:llm_metrics`, etc.)
- **Paginated trace output** — `get_run_details` now paginates trace
events via cursor, caching the full trace in a temp file so subsequent
pages don't re-fetch
- **MCP tool annotations** — all tools now have
`readOnlyHint`/`destructiveHint` annotations for clients that support
them
- **Project-scoped profile persistence** — `switch_profile` saves to
`.trigger/mcp.json` (gitignored), automatically loaded on next MCP
server start

### Context optimizations

- `get_query_schema` requires a table name — returns one table's schema
instead of all tables (60-80% fewer tokens)
- `get_current_worker` no longer inlines payload schemas — use
`get_task_schema` for specific tasks
- Query results formatted as text tables instead of JSON (~50% fewer
tokens for flat data)
- `cancel_run`, `list_deploys`, `list_preview_branches` formatted as
text instead of raw `JSON.stringify()`
- Schema and dashboard API responses cached (1hr and 5min respectively)

### Bug fixes

- Fixed `search_docs` failing due to renamed upstream Mintlify tool
(`SearchTriggerDev` → `search_trigger_dev`)
- Fixed `list_deploys` failing when deployments have null
`runtime`/`runtimeVersion` fields (fixes #3139)
- Fixed `list_preview_branches` crashing due to incorrect response shape
access
- Fixed `metrics` table column documented as `value` instead of
`metric_value` in query docs
- Fixed `/api/v1/query` not accepting JWT auth (added `allowJWT: true`)

### Dev CLI build directory fix

The dev CLI was leaking `build-*` directories in `.trigger/tmp/` on
every rebuild, accumulating hundreds of MB over time (842MB observed).
Three layers of protection added:

1. **During session**: deprecated workers are pruned (capped at 2
retained) when no active runs reference them, preventing unbounded
accumulation
2. **On SIGKILL/crash**: the watchdog process now cleans up
`.trigger/tmp/` when it detects the parent CLI was killed
3. **On next startup**: existing `clearTmpDirs()` wipes any remaining
orphans

## Test plan

- [ ] `pnpm run mcp:smoke` — 17 automated smoke tests for all read-only
MCP tools
- [ ] `pnpm run mcp:test list` — verify 25 tools registered (21 in
`--readonly` mode)
- [ ] `pnpm run mcp:test --readonly list` — verify write tools hidden
- [ ] Manual: start dev server, trigger task, rebuild multiple times,
verify build dirs stay capped at 4
- [ ] Manual: SIGKILL the dev CLI, verify watchdog cleans up
`.trigger/tmp/`
- [ ] Verify new API endpoints return correct data: `GET
/api/v1/query/schema`, `GET /api/v1/query/dashboards`

Eric Allam 436f20efc6 feat(cli): auto-cancel dev runs on CLI exit via detached watchdog (#3191)
When the dev CLI exits (e.g. ctrl+c via pnpm), runs that were
mid-execution
previously stayed stuck in EXECUTING status for up to 5 minutes until
the
heartbeat timeout fired. Now they are cancelled within seconds.

The dev CLI spawns a lightweight detached watchdog process at startup.
The
watchdog monitors the CLI process ID and, when it detects the CLI has
exited,
calls a new POST /engine/v1/dev/disconnect endpoint to cancel all
in-flight
runs immediately (skipping PENDING_CANCEL since the worker is known to
be dead).

Watchdog design:
- Fully detached (detached: true, stdio: ignore, unref()) so it survives
  even when pnpm sends SIGKILL to the process tree
- Active run IDs maintained via atomic file write
(.trigger/active-runs.json)
- Single-instance guarantee via PID file (.trigger/watchdog.pid)
- Safety timeout: exits after 24 hours to prevent zombie processes
- On clean shutdown, the watchdog is killed (no disconnect needed)

Disconnect endpoint:
- Rate-limited: 5 calls/min per environment
- Capped at 500 runs per call
- Small counts (<= 25): cancelled inline with pMap concurrency 10
- Large counts: delegated to the bulk action system
- Uses finalizeRun: true to skip PENDING_CANCEL and go straight to
FINISHED

Run engine change:
- cancelRun() now respects finalizeRun when the run is in EXECUTING
status,
skipping the PENDING_CANCEL waiting state and going directly to FINISHED

# trigger.dev v4.4.2

## Summary
2 new features, 2 improvements, 8 bug fixes.

## Improvements
- Add input streams for bidirectional communication with running tasks.
Define typed input streams with `streams.input<T>({ id })`, then consume
inside tasks via `.wait()` (suspends the process), `.once()` (waits for
next message), or `.on()` (subscribes to a continuous stream). Send data
from backends with `.send(runId, data)` or from frontends with the new
`useInputStreamSend` React hook.
([#3146](https://github.com/triggerdotdev/trigger.dev/pull/3146))
- Add PAYLOAD_TOO_LARGE error to handle graceful recovery of sending
batch trigger items with payloads that exceed the maximum payload size
([#3137](https://github.com/triggerdotdev/trigger.dev/pull/3137))

## Bug fixes
- Fix slow batch queue processing by removing spurious cooloff on
concurrency blocks and fixing a race condition where retry attempt
counts were not atomically updated during message re-queue.
([#3079](https://github.com/triggerdotdev/trigger.dev/pull/3079))
- fix(sdk): batch triggerAndWait variants now return correct
run.taskIdentifier instead of unknown
([#3080](https://github.com/triggerdotdev/trigger.dev/pull/3080))

## Server changes

These changes affect the self-hosted Docker image and Trigger.dev Cloud:

- Two-level tenant dispatch architecture for batch queue processing.
Replaces the
single master queue with a two-level index: a dispatch index (tenant →
shard)
and per-tenant queue indexes (tenant → queues). This enables O(1) tenant
selection and fair scheduling across tenants regardless of queue count.
Improves batch queue processing performance.
([#3133](https://github.com/triggerdotdev/trigger.dev/pull/3133))
- Add input streams with API routes for sending data to running tasks,
SSE reading, and waitpoint creation. Includes Redis cache for fast
`.send()` to `.wait()` bridging, dashboard span support for input stream
operations, and s2-lite support with configurable S2 endpoint, access
token skipping, and S2-Basin headers for self-hosted deployments. Adds
s2-lite to Docker Compose for local development.
([#3146](https://github.com/triggerdotdev/trigger.dev/pull/3146))
- Speed up batch queue processing by disabling cooloff and increasing
the batch queue processing concurrency limits on the cloud:
  
  - Pro plan: increase to 50 from 10.
  - Hobby plan: increase to 10 from 5.
- Free plan: increase to 5 from 1.
([#3079](https://github.com/triggerdotdev/trigger.dev/pull/3079))
- Move batch queue global rate limiter from FairQueue claim phase to
BatchQueue worker queue consumer for accurate per-item rate limiting.
Add worker queue depth cap to prevent unbounded growth that could cause
visibility timeouts.
([#3166](https://github.com/triggerdotdev/trigger.dev/pull/3166))
- Fix a race condition in the waitpoint system where a run could be
blocked by a completed waitpoint but never be resumed because of a
PostgreSQL MVCC issue. This was most likely to occur when creating a
waitpoint via `wait.forToken()` at the same moment as completing the
token with `wait.completeToken()`. Other types of waitpoints (timed,
child runs) were not affected.
([#3075](https://github.com/triggerdotdev/trigger.dev/pull/3075))
- Fix metrics dashboard chart series colors going out of sync and
widgets not reloading stale data when scrolled back into view
([#3126](https://github.com/triggerdotdev/trigger.dev/pull/3126))
- Gracefully handle oversized batch items instead of aborting the
stream.
  
When an NDJSON batch item exceeds the maximum size, the parser now emits
an error marker instead of throwing, allowing the batch to seal
normally. The oversized item becomes a pre-failed run with
`PAYLOAD_TOO_LARGE` error code, while other items in the batch process
successfully. This prevents `batchTriggerAndWait` from seeing connection
errors and retrying with exponential backoff.
  
Also fixes the NDJSON parser not consuming the remainder of an oversized
line split across multiple chunks, which caused "Invalid JSON" errors on
subsequent lines.
([#3137](https://github.com/triggerdotdev/trigger.dev/pull/3137))
- Require the user is an admin during an impersonation session.
Previously only the impersonation cookie was checked; now the real
user's admin flag is verified on every request. If admin has been
revoked, the session falls back to the real user's ID.

Eric Allam 540e1c86a4 feat: Input Streams - Bidirectional task communication (#3146)
Input streams enable sending typed data to executing tasks from external
callers — backends, frontends, or other tasks. This unlocks interactive
use cases like approval UIs, cancel buttons, chat interfaces, and
human-in-the-loop AI workflows where the task needs to receive data
while running.

Three consumption patterns inside a task:

* `.wait()` — Suspend the task until data arrives (process freed, most
efficient)
* `.once()` — Wait for the next message (process stays alive)
* `.on()` — Subscribe to a continuous stream of messages

One send pattern from outside:

* `.send(runId, data)` — Send typed data to a specific run's input
stream

## User-facing API

### Define a typed input stream

```ts
import { streams, task } from "@trigger.dev/sdk";

const approval = streams.input<{ approved: boolean; reviewer: string }>({ id: "approval" });
```

### Consume inside a task

```ts
export const myTask = task({
  id: "my-task",
  run: async () => {
    // Pattern 1: Suspend until data arrives (most efficient — frees the process)
    const result = await approval.wait({ timeout: "5m" });

    // Pattern 2: Wait for next message (process stays alive)
    const data = await approval.once().unwrap();

    // Pattern 3: Subscribe to multiple messages
    approval.on((data) => { /* handle each message */ });
  },
});
```

### Send from outside

```ts
// From a backend (using secret API key)
await approval.send(runId, { approved: true, reviewer: "alice" });

// From a frontend (using public JWT token from trigger response)
const { send } = useInputStreamSend("approval", runId, { accessToken });
send({ approved: true, reviewer: "alice" });
```

Eric Allam 469b039090 feat: OTEL metrics pipeline for task workers (#3061)
- Adds an end-to-end OTEL metrics pipeline: task workers collect and
export metrics via OpenTelemetry, the webapp ingests them into
ClickHouse, and they're queryable through the existing dashboard query
engine
- Workers emit process CPU/memory metrics (via
`@opentelemetry/host-metrics`) and Node.js runtime metrics (event loop
utilization, event loop delay, heap usage)
- Users can create custom metrics in their tasks via
`otel.metrics.getMeter()` from `@trigger.dev/sdk`
- Metrics are automatically tagged with run context (run ID, task slug,
machine, worker version) so they can be sliced per-run, per-task, or
per-machine
- The TSQL query engine gains metrics table support with typed attribute
columns, `prettyFormat()` for human-readable values, and per-schema time
bucket thresholds
- Includes reference tasks
(`references/hello-world/src/trigger/metrics.ts`) demonstrating
CPU-intensive, memory-ramp, bursty workload, and custom metrics patterns

## What changed

### Metrics collection (packages/core, packages/cli-v3)
- **Metrics export pipeline** — `TracingSDK` now sets up a
`MeterProvider` with a `PeriodicExportingMetricReader` that chains
through `TaskContextMetricExporter` (adds run context attributes) and
`BufferingMetricExporter` (batches exports to reduce overhead)
- **Host metrics** — Enabled `@opentelemetry/host-metrics` for process
CPU, memory, and system-level metrics
- **Node.js runtime metrics** — New `nodejsRuntimeMetrics.ts` module
using `performance.eventLoopUtilization()`, `monitorEventLoopDelay()`,
and `process.memoryUsage()` to emit 6 observable gauges
- File system and diskio metrics
- **Custom metrics** — Exposed `otel.metrics` from `@trigger.dev/sdk` so
users can create counters, histograms, and gauges in their tasks
- **Machine ID** — Stable per-worker machine identifier for grouping
metrics
- **Dev worker** — Drops `system.*` metrics to reduce noise, keeps
sending metrics between runs in warm workers

### Metrics ingestion (apps/webapp)
- **OTEL endpoint** — `otel.v1.metrics.ts` accepts OTEL metric export
requests (JSON and protobuf), converts to ClickHouse rows
- **ClickHouse schema** — `017_create_metrics_v1.sql` with 10-second
aggregation buckets, JSON attributes column, 60-day TTLs

### Query engine (internal-packages/tsql, apps/webapp)
- **Metrics query schema** — Typed columns for metric attributes
(`task_identifier`, `run_id`, `machine_name`, `worker_version`, etc.)
extracted from the JSON attributes column
- **`prettyFormat()`** — TSQL function that annotates columns with
format hints (`bytes`, `percent`, `durationSeconds`) for frontend
rendering without changing the underlying data
- **Per-schema time buckets** — Different tables can define their own
time bucket thresholds (metrics uses tighter intervals than runs)
- **AI query integration** — The AI query service knows about the
metrics table and can generate metric queries
- **Chart improvements** — Better formatting for byte values,
percentages, and durations in charts and tables

### Reference project
- **`references/hello-world/src/trigger/metrics.ts`** — 6 example tasks:
`cpu-intensive`, `memory-ramp`, `bursty-workload`, `sustained-workload`,
`concurrent-load`, `custom-metrics`

## Test plan

- [ ] Build all packages and webapp
- [ ] Start dev worker with hello-world reference project
- [ ] Run `cpu-intensive`, `memory-ramp`, and `custom-metrics` tasks
- [ ] Verify metrics in ClickHouse: `SELECT DISTINCT metric_name FROM
metrics_v1`
- [ ] Query via dashboard AI: "show me CPU utilization over time"
- [ ] Verify `prettyFormat` renders correctly in chart tooltips and
table cells
- [ ] Confirm dev worker drops `system.*` metrics but keeps `process.*`
and `nodejs.*`

# Releases
## @trigger.dev/sdk@4.4.0

### Minor Changes

- Added `query.execute()` which lets you query your Trigger.dev data
using TRQL (Trigger Query Language) and returns results as typed JSON
rows or CSV. It supports configurable scope (environment, project, or
organization), time filtering via `period` or `from`/`to` ranges, and a
`format` option for JSON or CSV output.
([#3060](https://github.com/triggerdotdev/trigger.dev/pull/3060))

    ```typescript
    import { query } from "@trigger.dev/sdk";
    import type { QueryTable } from "@trigger.dev/sdk";

    // Basic untyped query
const result = await query.execute("SELECT run_id, status FROM runs
LIMIT 10");

    // Type-safe query using QueryTable to pick specific columns
const typedResult = await query.execute<QueryTable<"runs", "run_id" |
"status" | "triggered_at">>(
      "SELECT run_id, status, triggered_at FROM runs LIMIT 10"
    );
    typedResult.results.forEach((row) => {
      console.log(row.run_id, row.status); // Fully typed
    });

    // Aggregation query with inline types
const stats = await query.execute<{ status: string; count: number }>(
      "SELECT status, COUNT(*) as count FROM runs GROUP BY status",
      { scope: "project", period: "30d" }
    );

    // CSV export
    const csv = await query.execute("SELECT run_id, status FROM runs", {
      format: "csv",
      period: "7d",
    });
    console.log(csv.results); // Raw CSV string
    ```

### Patch Changes

- Add `maxDelay` option to debounce feature. This allows setting a
maximum time limit for how long a debounced run can be delayed, ensuring
execution happens within a specified window even with continuous
triggers.
([#2984](https://github.com/triggerdotdev/trigger.dev/pull/2984))

    ```typescript
    await myTask.trigger(payload, {
      debounce: {
        key: "my-key",
        delay: "5s",
maxDelay: "30m", // Execute within 30 minutes regardless of continuous
triggers
      },
    });
    ```

- Aligned the SDK's `getRunIdForOptions` logic with the Core package to
handle semantic targets (`root`, `parent`) in root tasks.
([#2874](https://github.com/triggerdotdev/trigger.dev/pull/2874))

- Export `AnyOnStartAttemptHookFunction` type to allow defining
`onStartAttempt` hooks for individual tasks.
([#2966](https://github.com/triggerdotdev/trigger.dev/pull/2966))

- Fixed a minor issue in the deployment command on distinguishing
between local builds for the cloud vs local builds for self-hosting
setups.
([#3070](https://github.com/triggerdotdev/trigger.dev/pull/3070))

-   Updated dependencies:
    -   `@trigger.dev/core@4.4.0`

## @trigger.dev/build@4.4.0

### Patch Changes

-   Updated dependencies:
    -   `@trigger.dev/core@4.4.0`

## trigger.dev@4.4.0

### Patch Changes

- Fix runner getting stuck indefinitely when `execute()` is called on a
dead child process.
([#2978](https://github.com/triggerdotdev/trigger.dev/pull/2978))
- Add optional `timeoutInSeconds` parameter to the
`wait_for_run_to_complete` MCP tool. Defaults to 60 seconds. If the run
doesn't complete within the timeout, the current state of the run is
returned instead of waiting indefinitely.
([#3035](https://github.com/triggerdotdev/trigger.dev/pull/3035))
- Fixed a minor issue in the deployment command on distinguishing
between local builds for the cloud vs local builds for self-hosting
setups.

maxDelay: "30m", // Execute within 30 minutes regardless of continuous
triggers
      },
    });
    ```

- Fixed a minor issue in the deployment command on distinguishing
between local builds for the cloud vs local builds for self-hosting
setups.
([#3070](https://github.com/triggerdotdev/trigger.dev/pull/3070))

- fix: vendor superjson to fix ESM/CJS compatibility
([#2949](https://github.com/triggerdotdev/trigger.dev/pull/2949))

Bundle superjson during build to avoid `ERR_REQUIRE_ESM` errors on
Node.js versions that don't support `require(ESM)` by default (&lt;
22.12.0) and AWS Lambda which intentionally disables it.

- Add Vercel integration support to API schemas: `commitSHA` and
`integrationDeployments` on deployment responses, and `source` field for
environment variable imports.
([#2994](https://github.com/triggerdotdev/trigger.dev/pull/2994))

Saadi Myftija 7af789bc3e fix(deployments): external build token generation issue (#3070)
Fixes an issue introduced in #3024.

The behavior for local builds in older CLI versions relies on
`externalBuildData` to be defined to distinguish from the self-hosting
local build path, even though it doesn't actually use the token.

Matt Aitken d4cd34094e Query API and SDK (#3060)
Summary
- Add API endpoint to run TRQL queries
- Implement SDK function for executing queries

## SDK
Added `query.execute()` which lets you query your Trigger.dev data using
TRQL (Trigger Query Language) and returns results as typed JSON rows or

Eric Allam 062bcaece8 feat(mcp): add timeout parameter to wait_for_run_to_complete tool (#3035)
## Summary

- Adds an optional `timeoutInSeconds` parameter (default 60s) to the
`wait_for_run_to_complete` MCP tool
- If the run doesn't complete within the timeout, returns the current
run state instead of blocking indefinitely
- Uses `AbortSignal.timeout()` combined with the existing MCP signal

Fixes #3032

nicktrn 279102c17c fix(cli): reject execute() immediately when child process is dead (#2978)
## Summary
- When a child process crashes and a retry (`RETRY_IMMEDIATELY`) is
attempted on the same `TaskRunProcess`, `execute()` hangs forever
because the IPC send is silently skipped and the attempt promise can
never resolve
- This caused runner pods to stay up indefinitely with no heartbeats or
polls
- Fix: reject the attempt promise immediately when the child is not
connected, so the controller can proceed to warm start or exit

## Test plan
- [x] Added `taskRunProcess.test.ts` — verifies `execute()` rejects
promptly instead of hanging when the child process is dead
- [x] Deploy and verify no more stuck runner pods accumulate over time

nicktrn 70c8d6d14b fix(react-hooks): prevent onComplete from firing prematurely when stream disconnects (#2929)
## Summary

Fixes #2856 - The `onComplete` callback in `useRealtimeRun` was firing prematurely

## Root Cause

The callback was triggered when the long-poll stream ended, regardless
of whether the run had actually completed. Reverse proxies often close
idle connections, causing the stream to end prematurely. In this case it
was caused by fetch abort due to React strict mode.

## Fix

Changed the condition from checking if `run` exists to checking if
`run?.finishedAt` exists, ensuring `onComplete` only fires when the run
has reached a terminal state.

Eric Allam 31e4753122 fix(sdk): handle locked ReadableStream when retrying batch trigger (#2917)
When fetch crashes mid-stream during batch item upload (e.g., connection
reset, timeout), the request stream may remain locked by fetch's
internal reader. Attempting to cancel a locked stream throws 'Invalid
state: ReadableStream is locked', causing the batch operation to fail.

Added safeStreamCancel() helper that gracefully handles locked streams
by catching and ignoring the locked error. The stream will be cleaned up
by garbage collection when fetch eventually releases the reader.

Fixes customer issue where batchTrigger failed with ReadableStream
locked error during network instability.

Eric Allam 36168b3eb6 feat(sdk): expose user-provided idempotency key and scope in task context (#2903)
## Summary
- Store the original user-provided idempotency key and scope alongside
the hash
- Expose `ctx.run.idempotencyKey` as the user-provided key (not the
hash)
- Add `ctx.run.idempotencyKeyScope` to show the scope ("run", "attempt",
or "global")

<img width="539" height="450" alt="CleanShot 2026-01-19 at 11 40 46"
src="https://github.com/user-attachments/assets/b6f42991-697e-4314-a164-aef77b8fd25c"
/>

  ## Problem
Idempotency keys were hashed (SHA-256) before storage, making debugging
difficult since users couldn't see the value they originally set or
search for runs by idempotency key.

  ## Solution
Attach metadata to the `String` object returned by
`idempotencyKeys.create()` using a Symbol, extract it in the SDK before
the API call, and store it in the database alongside the hash.

  ```typescript
const key = await idempotencyKeys.create("my-key", { scope: "global" });
  await childTask.triggerAndWait(payload, { idempotencyKey: key });

  // In child task:
  ctx.run.idempotencyKey      // "my-key" (previously showed the hash)
  ctx.run.idempotencyKeyScope // "global"
```

  Test plan

  - Trigger task with idempotencyKeys.create() using different scopes (run, attempt, global)
  - Verify ctx.run.idempotencyKey returns user-provided key
  - Verify ctx.run.idempotencyKeyScope returns correct scope
  - Verify PostgreSQL stores idempotencyKeyOptions JSON
  - Verify ClickHouse receives idempotency_key_user and idempotency_key_scope via replication

Eric Allam 936bddf198 fix: upgrade Node.js to 20.20.0 to address async_hooks DoS vulnerability (#2890)
## Summary

- Upgrades Node.js from 20.19.0 to 20.20.0 (and 22.12.0 to 22.22.0 for
supervisor) to address the async_hooks stack overflow DoS vulnerability
- Adds `maxDepth` parameter (default 128) to `flattenAttributes` and
`unflattenAttributes` to prevent stack overflow on maliciously deep
nested structures

## Details

The vulnerability (patched in Node.js 20.20.0, 22.22.0, 24.13.0, 25.3.0)
causes unrecoverable crashes (exit code 7) when stack overflow occurs
during async_hooks callbacks. Since the webapp uses `AsyncLocalStorage`,
it was theoretically vulnerable.

### Changes

**Node.js version updates:**
- `docker/Dockerfile`: 20.11.1 → 20.20.0
- `apps/supervisor/Containerfile`: 22-alpine → 22.22.0-alpine
- `.nvmrc`: 20.19.0 → 20.20.0
- `apps/supervisor/.nvmrc`: 22.12.0 → 22.22.0
- `references/prisma-7/.nvmrc`: 20.19.0 → 20.20.0
- All GitHub workflows: 20.19.0 → 20.20.0

**Defense in depth:**
- Added `maxDepth` parameter to `flattenAttributes()` and
`unflattenAttributes()` in `packages/core` to prevent stack overflow on
deeply nested user input

## Test plan

- [x] All existing `flattenAttributes` tests pass (50 tests)
- [x] New tests for depth limiting added
- [x] Verify Docker builds work with new base images

Eric Allam 3875bb292a feat(engine): run debounce system (#2794)
Adds support for **debounced task runs** - when triggering a task with a
debounce key, subsequent triggers with the same key will reschedule the
existing delayed run instead of creating new runs. This continues until
no new triggers occur within the delay window.

## Usage

```typescript
await myTask.trigger({ userId: "123" }, {
  debounce: {
    key: "user-123-update",
    delay: "5s",
    mode: "leading", // default
  }
});
```

- **key**: Scoped to the task identifier
- **delay**: How long to wait before executing (supports duration
strings like `"5s"`, `"1m"`)
- **mode**: Either `"leading"` or `"trailing"`. Leading debounce will
use the payload and options from the first run created with the debounce
key. Trailing will use payload and options from the last run.

### "trailing" mode overrides

When using `mode: "trailing"` with debounce, the following options are
updated from the **last** trigger:

- **`payload`** - The task input data
- **`metadata`** - Run metadata
- **`tags`** - Run tags (replaces existing tags)
- **`maxAttempts`** - Maximum retry attempts
- **`maxDuration`** - Maximum compute time
- **`machine`**  - Machine preset (cpu/memory)

## Behavior

- **First run wins**: The first trigger creates the run, subsequent
triggers push its execution time later
- **Idempotency keys take precedence**: If both are specified,
idempotency is checked first
- **Max duration**: Configurable via `DEBOUNCE_MAX_DURATION_MS` env var
(default: 10 minutes)

Works with `triggerAndWait` - parent runs correctly block on the
debounced run.

Eric Allam a999d9ea3f feat(engine): Batch trigger reloaded (#2779)
New batch trigger system with larger payloads, streaming ingestion,
larger batch sizes, and a fair processing system.

This PR introduces a new `FairQueue` abstraction inspired by our own
`RunQueue` that enables multi-tenant fair queueing with concurrency
limits. The new `BatchQueue` is built on top of the `FairQueue`, and
handles processing Batch triggers in a fair manner with per-environment
concurrency limits defined per-org. Additionally, there is a global
concurrency limit to prevent the BatchQueue system from creating too
many runs too quickly, which can cause downstream issues.

For this new BatchQueue system we have a completely new batch trigger
creation and ingestion system. Previously this was a single endpoint
with a single JSON body that defined details about the batch as well as
all the items in the batch.

We're introducing a two-phase batch trigger ingestion system. In the
first phase, the BatchTaskRun record is created (and possibly rate
limited). The second phase is another endpoint that accepts an NDJSON
body with each line being a single item/run with payload and options.

At ingestion time all items are added to a queue, in order, and then
processed by the BatchQueue system.

## New batch trigger rate limits

This PR implements a new batch trigger specific rate limit, configured
on the `Organization.batchRateLimitConfig` column, and defaults using
these environment variables:

- `BATCH_RATE_LIMIT_REFILL_RATE` defaults to 10
- `BATCH_RATE_LIMIT_REFILL_INTERVAL` the duration interval, defaults to
`"10s"`
- `BATCH_RATE_LIMIT_MAX` defaults to 1200

This rate limiter is scoped to the environment ID and controls how many
runs can be submitted via batch triggers per interval. The SDK handles
the retrying side.

## Batch queue concurrency limits

The new column `Organization.batchQueueConcurrencyConfig` now defines an
org specific `processingConcurrency` value, with a backup of the env var
`BATCH_CONCURRENCY_LIMIT_DEFAULT` which defaults to 10. This controls
how many batch queue items are processed concurrently per environment.

There is also a global rate limit for the batch queue set via the
`BATCH_QUEUE_GLOBAL_RATE_LIMIT` which defaults to being disabled. If
set, the entire batch queue system won't process more than
`BATCH_QUEUE_GLOBAL_RATE_LIMIT` items per second. This allows
controlling the maximum number of runs created per second via batch
triggers.

## Batch trigger settings

- `STREAMING_BATCH_MAX_ITEMS` controls the maximum number of items in a
single batch
- `STREAMING_BATCH_ITEM_MAXIMUM_SIZE` controls the maximum size of each
item in a batch
- `BATCH_CONCURRENCY_DEFAULT_CONCURRENCY` controls the default
environment concurrency
- `BATCH_QUEUE_DRR_QUANTUM` how many credits each environment gets each
round for the DRR scheduler
- `BATCH_QUEUE_MAX_DEFICIT` the maximum deficit for the DRR scheduler
- `BATCH_QUEUE_CONSUMER_COUNT` how many queue consumers to run
- `BATCH_QUEUE_CONSUMER_INTERVAL_MS` how frequently they poll for items
in the queue

### Configuration Recommendations by Use Case

**High-throughput priority (fairness acceptable at 0.98+):**

```env
BATCH_QUEUE_DRR_QUANTUM=25
BATCH_QUEUE_MAX_DEFICIT=100
BATCH_QUEUE_CONSUMER_COUNT=10
BATCH_QUEUE_CONSUMER_INTERVAL_MS=50
BATCH_CONCURRENCY_DEFAULT_CONCURRENCY=25
```

**Strict fairness priority (throughput can be lower):**

```env
BATCH_QUEUE_DRR_QUANTUM=5
BATCH_QUEUE_MAX_DEFICIT=25
BATCH_QUEUE_CONSUMER_COUNT=3
BATCH_QUEUE_CONSUMER_INTERVAL_MS=100
BATCH_CONCURRENCY_DEFAULT_CONCURRENCY=5
```
