Adds region-level gating so MICROVM regions are only visible and usable
by orgs with the `hasComputeAccess` feature flag. Admins and explicit
allowlist behavior unchanged.
- New shared helper (`regionAccess.server.ts`) with
`resolveComputeAccess`, `defaultVisibilityFilter`, and
`isComputeRegionAccessible`
- `RegionsPresenter` filters out MICROVM regions for non-compute orgs
- `SetDefaultRegionService` blocks setting a MICROVM region as default
without compute access
- `WorkerGroupService` blocks triggering runs in MICROVM regions without
compute access
- `computeTemplateCreation` refactored to use shared
`resolveComputeAccess`
- Updated snapshot callback schema
Sets `application_name` on the Prisma writer and replica connection
strings using the existing `SERVICE_NAME` env var, so DB load can be
attributed by service.
A single "fetch failed" from the object store was aborting the entire
batch stream with no retry. Added p-retry (3 attempts, 500ms-2s backoff)
around ploadPacketToObjectStore so transient network errors self-heal
server-side instead of propagating to the SDK.
### Text wrapping fix
- Fixes message text not wrapping on the run inspector if there were no
spaces in the text
- Fixes inspector title truncation
- Adds a copy text button for the Message property

This is a small improvement mainly with the UI Skills file:
- Animate open and close the Resizable panels
- Uses the built in animation hooks from react-window-splitter
- Includes a global variable for the animation easing and timing for
consistency

## Summary
- Drop all 8 foreign key constraints on TaskRun. The run listing path is
now fully ClickHouse-backed so we no longer need Postgres to enforce
referential integrity on this table. The FK constraints add write
overhead on every insert/update with no remaining benefit. Prisma
queries are unaffected.
- Remove PostgresRunsRepository and its associated feature flag
(runsListRepository), which was the last remaining code path querying
TaskRun directly for list/count operations.
- Drop three indexes that were only useful for the Postgres run list
path and have no remaining query consumers:
- TaskRun_runtimeEnvironmentId_id_idx — was the cursor pagination index
for PostgresRunsRepository; superseded by the (runtimeEnvironmentId,
createdAt DESC) composite index
- TaskRun_scheduleId_idx — redundant with the (scheduleId, createdAt
DESC) composite index; no direct Postgres queries filter by scheduleId
alone
- TaskRun_rootTaskRunId_idx — no queries filter TaskRun by rootTaskRunId
as a WHERE clause anywhere in the codebase
All index drops use CONCURRENTLY IF EXISTS to avoid table locks in
production.
## Test plan
- pnpm run db:migrate:deploy applies all migrations cleanly
- pnpm run typecheck --filter webapp passes
- Run list pages load correctly in the dashboard (ClickHouse path)
- Scheduled task runs still trigger and appear correctly
This allows seamless migration to different object storage.
Existing runs that have offloaded payloads/outputs will continue to use
the default object store (configured using `OBJECT_STORE_*` env vars).
You can add additional stores by setting new env vars:
- `OBJECT_STORE_DEFAULT_PROTOCOL` this determines where new run large
payloads will get stored.
- If you set that you need to set new env vars for that protocol.
Example:
```
OBJECT_STORE_DEFAULT_PROTOCOL=“s3"
OBJECT_STORE_S3_BASE_URL=https://s3.us-east-1.amazonaws.com
OBJECT_STORE_S3_ACCESS_KEY_ID=<val>
OBJECT_STORE_S3_SECRET_ACCESS_KEY=<val>
OBJECT_STORE_S3_REGION=us-east-1
OBJECT_STORE_S3_SERVICE=s3
```

## Summary
Currently, every triggered run follows a two-step path through Redis:
1. **Enqueue** — A Lua script atomically adds the message to a queue
sorted set (ordered by priority-adjusted timestamp)
2. **Dequeue** — A debounced `processQueueForWorkerQueue` job fires
~500ms later, checks concurrency limits, removes the message from the
sorted set, and pushes it to a worker queue (Redis list) where workers
pick it up via `BLPOP`
This means every run pays at least ~500ms of latency between being
triggered and being available for a worker to execute, even when the
queue is empty and concurrency is wide open.
### What changed
The enqueue Lua scripts now atomically decide whether to **skip the
queue sorted set entirely** and push directly to the worker queue. This
happens inside the same Lua script that handles normal enqueue, so the
decision is atomic with respect to concurrency bookkeeping.
A run takes the **fast path** when all of these are true:
- **Fast path is enabled** for this worker queue (gated per
`WorkerInstanceGroup`)
- **No available messages** in the queue (`ZRANGEBYSCORE` finds nothing
with score ≤ now) — this respects priority ordering and allows fast path
even when the queue has future-scored messages (e.g. nacked retries with
delay)
- **Environment concurrency** has capacity
- **Queue concurrency** has capacity (including per-concurrency-key
limits for CK queues)
When the fast path is taken:
- The message is stored and pushed directly to the worker queue
(`RPUSH`)
- Concurrency slots are claimed (`SADD` to the same sets used by the
normal dequeue path)
- The `processQueueForWorkerQueue` job is **not scheduled** (no work to
do)
- TTL sorted set is skipped (the `expireRun` worker job handles TTL
independently)
When any condition fails, the existing slow path runs unchanged.
### Rollout gating
- **Development environments**: Fast path is always enabled
- **Production environments**: Gated by a new `enableFastPath` boolean
on `WorkerInstanceGroup` (defaults to `false`), allowing
region-by-region rollout
### Rolling deploy safety
Each process registers its own Lua scripts via `defineCommand`
(identified by SHA hash). Old and new processes never share scripts. The
Redis data structures are fully compatible in both directions — ack,
nack, and release operations work identically regardless of which path a
message took.
## Test plan
- [x] Fast path taken when queue is empty and concurrency available
- [x] Slow path when `enableFastPath` is false
- [x] Slow path when queue has available messages (respects priority
ordering)
- [x] Fast path when queue only has future-scored messages
- [x] Slow path when env concurrency is full
- [x] Fast-path message can be acknowledged correctly
- [x] Fast-path message can be nacked and re-enqueued to the queue
sorted set
- [x] Run all existing run-queue tests (ack, nack, CK, concurrency
sweeper, dequeue) to verify no regressions
- [x] Typecheck passes for run-engine and webapp
Add TTL (time-to-live) defaults at task-level and config-level, with
precedence: per-trigger > task > config > dev default (10m).
Docs PR: #3200 (merge after packages are released)
Adds a dialog to the admin orgs page for viewing and editing per-org
feature flag overrides. Flags are introspected from the catalog so the
UI stays in sync with available flags automatically. Also adds a new tab
for global flags.
Refactors featureFlags.server.ts to split catalog definition (shared)
from server-only runtime (flags(), makeSetMultipleFlags). The shared
module exports flag metadata and validation so both the UI and API
routes can use it without pulling in server dependencies.
Adds support for taint tolerations for scheduled runs. Useful for
selectively tolerating taints on dedicated node pools.
The new `KUBERNETES_SCHEDULED_RUN_TOLERATIONS` env variable accepts a
comma-separated list in the format key=value:effect (or key:effect for
the Exists operator).
Drive-by: renames all `KUBERNETES_SCHEDULE_*` affinity env vars to
KUBERNETES_SCHEDULED_RUN_* for clarity — this feature isn't used in
production yet or published in a tagged image; the name change is fine.
For human reviewer:
- Check if Redis connection + code makes sense
- Check CLI methods (it's on a hotpath)
- Check DB Migrations and new tables

💯
Adds three new top-level columns to the ClickHouse task_runs_v2 table
primarily for analytics:
- `trigger_source` / `root_trigger_source` - extracted from the existing
TaskRun.annotations JSON during WAL
replication
- `is_warm_start` - new nullable boolean on TaskRun in Postgres, set in
the existing taskRun.update() at attempt
start (no additional write). null until the first attempt starts.
Run region is already available via the existing `worker_queue` column
in ClickHouse.
Scheduled runs create predictable hourly spikes that compete with
on-demand runs for node capacity. Runs triggered "on-demand" via the
SDK, API, or dashboard, are more sensitive to cold start latency since
users are typically
waiting on the result. When a burst of scheduled runs lands at the top
of the hour, it can saturate the shared pool resources causing
contention, affecting cold starts across the board.
The idea in this change is to absorb these periodic spikes in a
dedicated pool without affecting the cold starts of on-demand runs.
Scheduled runs are inherently less sensitive to cold starts.
### Changes in this PR
Follows up on run annotations (#3241), which made trigger origin
available on every run in the tree. This PR exposes
annotations at dequeue time to the supervisor. This enables scheduling
decisions based on trigger source.
The affinities are soft preferences at schedule time, so runs fall back
gracefully if the target pool is out out of capacity.
Queue limit ServiceValidationErrors were being logged at error level.
These are
expected validation rejections, not bugs.
- Add logLevel property to ServiceValidationError (webapp + run-engine)
- Set logLevel: warn on all queue limit throws
- Schedule engine: detect queue limit failures and log as warn
- Redis-worker: respect logLevel on thrown errors
Adds an `annotations` JSONB column to task runs that captures where and
how each run was triggered.
This enables filtering and analyzing trigger origins without querying up
the run tree. Also enables making scheduling decisions based on the
trigger source, e.g., use separate affinities for scheduled runs.
Each run records:
- **triggerSource**: who initiated it (sdk, api, dashboard, cli, mcp,
schedule)
- **triggerAction**: what kind of action (trigger, replay, test)
- **rootTriggerSource**: the trigger source of the root ancestor,
propagated through the entire run
tree
- **rootScheduleId**: schedule id, in case the run tree was triggered
from a schedule
Currently the main motivation for annotations it to determine whether a
run is part of a schedule-originated tree without traversing ancestors.
### A couple of design considerations
- **Decoupled source from method**: triggerSource and triggerAction are
separate fields to avoid
combinatorial explosion (every new source × every new action)
- **Server-side first**: all annotation values are primarily determined
on the server, only a minor SDK change needed
- **Forward-compatible**: annotation fields use
`z.enum([...]).or(anyString)` so new values can be
added without breaking validation; we currently don't need an explicit
version field for annotations.
Note: `metadata` would have been a more fitting name for the db column,
as it is consistent with other tables where we store this type of
information. It is already in use to store user metadata though, so we
go with `annotations` instead.
- Full prompt management UI: list, detail, override, and version
management for AI prompts defined with `prompts.define()`
- Rich AI span inspectors for all AI SDK operations with token usage,
messages, and prompt context
- Real-time generation tracking with live polling and filtering
## Prompt management
Define prompts in your code with `prompts.define()`, then manage
versions and overrides from the dashboard without redeploying:
```typescript
import { task, prompts } from "@trigger.dev/sdk";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";
import { z } from "zod";
const supportPrompt = prompts.define({
id: "customer-support",
model: "gpt-4o",
variables: z.object({
customerName: z.string(),
plan: z.string(),
issue: z.string(),
}),
content: `You are a support agent for Acme SaaS.
Customer: {{customerName}} ({{plan}} plan)
Issue: {{issue}}
Respond with empathy and precision.`,
});
export const supportTask = task({
id: "handle-support",
run: async (payload) => {
const resolved = await supportPrompt.resolve({
customerName: payload.name,
plan: payload.plan,
issue: payload.issue,
});
const result = await generateText({
model: openai(resolved.model ?? "gpt-4o"),
system: resolved.text,
prompt: payload.issue,
...resolved.toAISDKTelemetry(),
});
return { response: result.text };
},
});
```
The prompts list page shows each prompt with its current version, model,
override status, and a usage sparkline over the last 24 hours.
From the prompt detail page you can:
- **Create overrides** to change the prompt template or model without
redeploying. Overrides take priority over the deployed version when
`prompt.resolve()` is called.
- **Promote** any code-deployed version to be the current version
- **Browse generations** across all versions with infinite scroll and
live polling for new results
- **Filter** by version, model, operation type, and provider
- **View metrics** (total generations, avg tokens, avg cost, latency)
broken down by version
## AI span inspectors
Every AI SDK operation now gets a custom inspector in the run trace
view:
- **`ai.generateText` / `ai.streamText`** — Shows model, token usage,
cost, the full message thread (system prompt, user message, assistant
response), and linked prompt details
- **`ai.generateObject` / `ai.streamObject`** — Same as above plus the
JSON schema and structured output
- **`ai.toolCall`** — Shows tool name, call ID, and input arguments
- **`ai.embed`** — Shows model and the text being embedded
For generation spans linked to a prompt, a "Prompt" tab shows the prompt
metadata, the input variables passed to `resolve()`, and the template
content from the prompt version.
All AI span inspectors include a compact timestamp and duration header.
## Other improvements
- Resizable panel sizes now persist across page refreshes (patched
`@window-splitter/state` to fix snapshot restoration)
- Run page panels also persist their sizes
- Fixed `<div>` inside `<p>` DOM nesting warnings in span titles and
chat messages
- Added Operations and Providers filters to the AI metrics dashboard

## Summary
Major expansion of the MCP server (14 → 25 tools), context efficiency
optimizations, new API endpoints, and a fix for the dev CLI leaking
build directories on disk.
### New MCP tools
- **Query & analytics**: `get_query_schema`, `query`, `list_dashboards`,
`run_dashboard_query` — query your data using TRQL directly from AI
assistants
- **Profile management**: `whoami`, `list_profiles`, `switch_profile` —
see and switch CLI profiles per-project (persisted to
`.trigger/mcp.json`)
- **Dev server control**: `start_dev_server`, `stop_dev_server`,
`dev_server_status` — start/stop `trigger dev` and stream build output
- **Task introspection**: `get_task_schema` — get payload schema for a
specific task (split out from `get_current_worker` to reduce context)
### New API endpoints
- `GET /api/v1/query/schema` — discover TRQL tables and columns
(server-driven, multi-table)
- `GET /api/v1/query/dashboards` — list built-in dashboard widgets and
their queries
### New features
- **`--readonly` flag** — hides write tools (`deploy`, `trigger_task`,
`cancel_run`) so agents can't make changes
- **`read:query` JWT scope** — new authorization scope for query
endpoints, with per-table granularity (`read:query:runs`,
`read:query:llm_metrics`, etc.)
- **Paginated trace output** — `get_run_details` now paginates trace
events via cursor, caching the full trace in a temp file so subsequent
pages don't re-fetch
- **MCP tool annotations** — all tools now have
`readOnlyHint`/`destructiveHint` annotations for clients that support
them
- **Project-scoped profile persistence** — `switch_profile` saves to
`.trigger/mcp.json` (gitignored), automatically loaded on next MCP
server start
### Context optimizations
- `get_query_schema` requires a table name — returns one table's schema
instead of all tables (60-80% fewer tokens)
- `get_current_worker` no longer inlines payload schemas — use
`get_task_schema` for specific tasks
- Query results formatted as text tables instead of JSON (~50% fewer
tokens for flat data)
- `cancel_run`, `list_deploys`, `list_preview_branches` formatted as
text instead of raw `JSON.stringify()`
- Schema and dashboard API responses cached (1hr and 5min respectively)
### Bug fixes
- Fixed `search_docs` failing due to renamed upstream Mintlify tool
(`SearchTriggerDev` → `search_trigger_dev`)
- Fixed `list_deploys` failing when deployments have null
`runtime`/`runtimeVersion` fields (fixes#3139)
- Fixed `list_preview_branches` crashing due to incorrect response shape
access
- Fixed `metrics` table column documented as `value` instead of
`metric_value` in query docs
- Fixed `/api/v1/query` not accepting JWT auth (added `allowJWT: true`)
### Dev CLI build directory fix
The dev CLI was leaking `build-*` directories in `.trigger/tmp/` on
every rebuild, accumulating hundreds of MB over time (842MB observed).
Three layers of protection added:
1. **During session**: deprecated workers are pruned (capped at 2
retained) when no active runs reference them, preventing unbounded
accumulation
2. **On SIGKILL/crash**: the watchdog process now cleans up
`.trigger/tmp/` when it detects the parent CLI was killed
3. **On next startup**: existing `clearTmpDirs()` wipes any remaining
orphans
## Test plan
- [ ] `pnpm run mcp:smoke` — 17 automated smoke tests for all read-only
MCP tools
- [ ] `pnpm run mcp:test list` — verify 25 tools registered (21 in
`--readonly` mode)
- [ ] `pnpm run mcp:test --readonly list` — verify write tools hidden
- [ ] Manual: start dev server, trigger task, rebuild multiple times,
verify build dirs stay capped at 4
- [ ] Manual: SIGKILL the dev CLI, verify watchdog cleans up
`.trigger/tmp/`
- [ ] Verify new API endpoints return correct data: `GET
/api/v1/query/schema`, `GET /api/v1/query/dashboards`

## Adds 2 self serve features
### 1. self serve preview branches
- Copies the patterns of the self serve concurrency
- Self serve only available on Pro plan (otherwise you are linked to the
billing plans page)
- Global self serve branches limit: 180 (+20 for the Pro plan). It can
be overridden per Org
- You need to archive branches before reducing the number of extra
branches you're paying for
- Branches are removed immediately but remain billed until the end of
the billing cycle like extra concurrency
### 2. self serve team members
- Copies the patterns of the self serve concurrency
- Self serve only available on Pro plan (otherwise you are linked to the
billing plans page)
- Global self serve members is unlimited but can be limited with the
same env var quota and overridden per org if needed
- You need to remove team members before reducing the number of members
you pay for
- Team members are removed immediately but remain billed until the end
of the billing cycle like extra concurrency
When the dev CLI exits (e.g. ctrl+c via pnpm), runs that were
mid-execution
previously stayed stuck in EXECUTING status for up to 5 minutes until
the
heartbeat timeout fired. Now they are cancelled within seconds.
The dev CLI spawns a lightweight detached watchdog process at startup.
The
watchdog monitors the CLI process ID and, when it detects the CLI has
exited,
calls a new POST /engine/v1/dev/disconnect endpoint to cancel all
in-flight
runs immediately (skipping PENDING_CANCEL since the worker is known to
be dead).
Watchdog design:
- Fully detached (detached: true, stdio: ignore, unref()) so it survives
even when pnpm sends SIGKILL to the process tree
- Active run IDs maintained via atomic file write
(.trigger/active-runs.json)
- Single-instance guarantee via PID file (.trigger/watchdog.pid)
- Safety timeout: exits after 24 hours to prevent zombie processes
- On clean shutdown, the watchdog is killed (no disconnect needed)
Disconnect endpoint:
- Rate-limited: 5 calls/min per environment
- Capped at 500 runs per call
- Small counts (<= 25): cancelled inline with pMap concurrency 10
- Large counts: delegated to the bulk action system
- Uses finalizeRun: true to skip PENDING_CANCEL and go straight to
FINISHED
Run engine change:
- cancelRun() now respects finalizeRun when the run is in EXECUTING
status,
skipping the PENDING_CANCEL waiting state and going directly to FINISHED
### Fixes and improvements to the onboarding questions:
**This change is worth double checking @matt-aitken**
- Update to the Button.tsx file: it now takes `isLoading` that shows a
spinner in the middle of the button (replacing the button text and any
icons) and sets it to `disabled`. It does this nicely by keeping the
button width the same so there's no layout shift.
**Other fixes**
- Fixes an issue where if you type a custom option in the "What
technologies do you use" question, it doesn't check the list to see if
it matches. Now it checks the box if you've typed an option from that
list.
- When we randomize the list of onboarding question options, we now
store the position they appeared in the list

Add a tabbed sidebar to the Test page for standard tasks, reusing the
ClientTabs pattern from the Query page.
- Options tab: existing sidebar content (machine, version, queue, etc.)
- AI tab: AI-powered payload generation with streaming, supports JSON
Schema, inferred schema from recent runs, and task source code lookup
via tool calling for tasks without schemas
- Schema tab: displays payload JSON Schema (from schemaTask), inferred
schema (from recent runs via @jsonhero/schema-infer), or empty state
with schemaTask docs and example code
Data layer changes:
- Surface payloadSchema and inferredPayloadSchema from TestTaskPresenter
- Add payloadSchema and fileId to WorkerDeploymentWithWorkerTasks type
- Decompress zlib-deflated source files for AI context
A top-level Errors page that aggregates errors from failed runs with
occurrences metrics.
https://github.com/user-attachments/assets/8f0ef55e-90dd-4faa-9051-59f4665181e4
Errors are “fingerprinted” so similar errors are grouped together (e.g.
has an ID in the error message).
You can view an individual error to view a timeline of when it fired,
the runs, and bulk replay them.
The global rate limiter was being applied at the FairQueue claim phase,
consuming 1 token per queue-claim-attempt rather than per item
processed.
With many small queues (each batch is its own queue), consumers burned
through tokens on empty or single-item queues, causing aggressive
throttling well below the intended items/sec limit.
Changes:
- Move rate limiter from FairQueue claim phase to BatchQueue worker
queue
consumer loop (before blockingPop), so each token = 1 item processed
- Replace the FairQueue rate limiter with a worker queue depth cap to
prevent unbounded growth that could cause visibility timeouts
- Add BATCH_QUEUE_WORKER_QUEUE_MAX_DEPTH env var (optional, disabled by
default)
