## 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.

Eric Allam 2dd9f37b40 fix(core,cli): stop chat.agent uncaught exception on mid-stream abort (#3792) 
## 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.

Eric Allam e9e2ec1cfc fix(sdk): re-apply tool toModelOutput across chat.agent turns (#3790) 
## 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`.

Daniel Sutton e1950778e2 feat(webapp): mollifier API mutations on buffered runs (#3756) 
## 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`
- `resetIdempotencyKey.server.ts`

Stacked on the reads PR.

Daniel Sutton 4745754a7a feat(webapp,run-engine): mollifier drainer replay + stale sweep + cancelled-run engine API (#3754) 
## 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`).

Stacked on the trigger-time decisions PR.

---

## 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.

Daniel Sutton 20a676d2ed fix(core,webapp): coerce numeric concurrencyKey to string (#3789) 
## 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.

Daniel Sutton 3924aa4adb feat(redis-worker,webapp): mollifier buffer extensions + snapshot type (#3752) 
## 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

## 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.

nicktrn c043c4a6ad fix(core): external trace context leaks across warm-started runs (#3768) 
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.

Iss 8399aa2052 fix(core): retry TASK_MIDDLEWARE_ERROR under the task's retry policy (#3676) 
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.

## 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.

    import { TriggerClient } from "@trigger.dev/sdk";

const prod = new TriggerClient({ accessToken:
process.env.TRIGGER_PROD_KEY });

Eric Allam 75679c7518 fix(sdk): chat HITL continuations no longer break the next LLM call (#3719) 
## 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

Eric Allam 832cf7220b feat(sdk,core): add TriggerClient for per-instance SDK configuration (#3683) 
## 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

Eric Allam 5ddb81ac8d fix(cli): stop chat.agent skills silently disappearing from trigger dev (#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

nicktrn dbf9b4e7e5 fix(core,cli): register tasks loaded via dynamic import during run (#3688) 
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)

`useChat` hook. Text streaming, tool calls, reasoning, and `data-*`

- 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

- 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

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

- 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))

    ```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 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.

Eric Allam 9ff410bfa4 feat(sdk): type chat.createStartSessionAction against your chat agent (#3684) 
## 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

Eric Allam d343727021 fix(webapp,sdk): keep chat.agent snapshots on one object store (#3679) 
(`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.

Eric Allam f91b96efb7 feat(sdk,core): preserve chat.agent context after cancel / OOM / crash (#3671) 2026-05-20 07:27:05 +01:00
Eric Allam 12d2125148 fix(sdk,core,build): SDK hardening pass (#3670) 
## 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.

Eric Allam 427d9e078a feat(sdk): functional baseURL and fetch override on chat transports (#3655) 
## 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.

Eric Allam 8b98e21b4b fix(sdk,core): cache realtime-stream credentials per slot with refresh on writer failure (#3658) 
## 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.

Daniel Sutton 906d5fafb6 feat(mollifier): trigger burst smoothing — Phase 1 (monitoring) (#3614) 
## 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`

Eric Allam 82853debea feat(webapp,core,sdk,cli): bound session.out via per-turn trim (#3644) 
## 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.

Eric Allam 55fa2d4967 fix(cli): TRIGGER_BUILD_SKIP_REWRITE_TIMESTAMP escape hatch for local self-hosted builds (#3618) 
## 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.

Eric Allam 627e059298 feat(trigger-sdk): add streamBaseURL to TriggerChatTransport (#3641) 
`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.

Eric Allam dfa3ede209 feat(ci): support release candidates via changesets pre mode (#3628) 
## 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.

Eric Allam 4c42f6cc0b feat(webapp,core,cli): filter runs by region in dashboard, API, and MCP (#3612) 
## 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" })
```

Eric Allam ac02c0f709 fix(core): drop unique-symbol brand on LocalsKey to fix dual-package builds (#3626) 
## 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`

Eric Allam 16720a5e62 feat(sdk): chat.agent — runtime + browser transport 
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.

Eric Allam 979655c281 feat: Sessions dashboard, task_kind, and chat-ready hardening (1/4) (#3542) 
## 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.

## Stack

Part of a 4-PR stack. Merge bottom-up.

1. **This PR** (#3542) → `main`
2. #3543 → #3542 — `chat.agent` runtime + browser transport

Daniel Sutton 09f5354a03 fix(core): cap idempotencyKey length at the API boundary (#3560) 
`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.

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.

Matt Aitken e4981d1b11 feat(webapp): consolidate auth path + add comprehensive auth tests (#3499) 
## 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

Matt Aitken 8e675a4e93 fix(core): retry TASK_PROCESS_SIGSEGV under the user's retry policy (#3552) 
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.

## Test plan

- [x] `pnpm exec vitest run test/errors.test.ts` in `packages/core` —
26/26 pass (4 new)
- [x] `pnpm run build --filter @trigger.dev/core`
- [ ] CI green on PR

## 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.

Matt Aitken 62e006617e fix(cli): fail attempt on uncaught exception instead of hanging to maxDuration (TRI-9117) (#3529)
⚒️ Publish Worker (v4) / build (supervisor) (push) Has been cancelled
Details 
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.

Eric Allam b65a04eb37 fix(cli,core): stop dev workers spinning at 100% CPU after parent CLI disconnect (#3491) 
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.

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.

`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.

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
by `wait.forToken()` is unchanged.

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.
- [ ] `POST /api/v1/sessions` and verify the row replicates to
`trigger_dev.sessions_v1` within a couple of seconds.
- [ ] `POST /api/v1/sessions/:id/close`, then confirm `POST
/realtime/v1/sessions/:id/out/append` returns 400.
- [ ] Reuse a closed session's `externalId` on `POST /api/v1/sessions`
and confirm 409.
- [ ] `GET /realtime/v1/sessions/:id/out` with `X-Peek-Settled: 1` after
a turn completes and confirm `X-Session-Settled: true` response header +
immediate close.

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.

---

## 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)

13 |

## Notes

- **mcp-sdk chain**: `@vercel/sdk` in webapp imports `Vercel` API client
only; `mcp-server/*` subpath isn't loaded at runtime. cli-v3's MCP
server runs only via `trigger mcp` on developer machines. Bumping
`@modelcontextprotocol/sdk` to latest (1.29.0) wouldn't close these
alerts anyway - it ships hono ^4.11.4 which is still vulnerable - so
dismissal is the cleaner call.
- **References ignore list**: confirmed with current dependabot ignore
config; added `references/seed/package.json` (only gap).
- **undici** alerts (CVE-2026-1527, 4 alerts) will auto-close: lockfile
already at 6.25.0 > patched 6.24.0; just needs Dependabot rescan.
- **Effect 3.20 fix** is a runtime-only scheduler fix, no public API
changes - verified with research agent against our four `effect/*`
imports.
- **uuid 14** is ESM-only; we only call `validate`/`version` (no crypto
needed) so Node 20 requirement isn't load-bearing for us.
## Public packages (`packages/*`)

Minimal surface, deliberately. None of these change published runtime
behaviour - all changesets-worthy public package changes are deferred to
a regular release pass.

| Package | Change | Runtime impact |
|---|---|---|
| `packages/trigger-sdk` | Removed dead `uuid` dep (no source imports) |
None - dep was unused |
| `packages/cli-v3` | `tar` ^7.5.4 → ^7.5.13 | Patch bump within
already-allowed 7.x range; nothing CLI consumers see |
| `packages/core` / `packages/build` / `packages/python` /
`packages/rsc` / `packages/react-hooks` / `packages/schema-to-json` |
`rimraf` ^3.0.2 → ^6.0.1 in devDeps | Build-time only, no runtime change
|

No changeset added because nothing in these packages affects what
published consumers run.

## Validation

- Webapp typecheck (forced, no cache) passes after every commit
- Smoke-tested testcontainers v11 changes via real `postgresTest` +
`redisTest` (sync.test.ts, releaseConcurrency.test.ts) - both pass
- Webapp built + verified `require("uuid")` no longer in CJS server
output (now bundled inline)
- Test env webapp deployed at `dependabot-q2.rc0` (cloud#740) - no
issues observed
- Test suite run with package prerelease passed

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)
