## Summary
Several docs pages rendered identical `<title>` tags, which weakens
search indexing and makes results ambiguous. Each affected page now has
a unique, descriptive title while keeping its existing sidebar label
unchanged.
Alongside the retitles:
- Removed two stale build-system upgrade pages that were no longer in
the navigation, with redirects to the current package upgrade guide.
- Redirected the build-extensions group index to its overview page so
the two URLs stop sharing a title.
- Dropped a leftover orphaned API reference page (its old URL already
redirects to the management overview).
No links break: nothing in the docs points at the removed pages, and
every redirect target exists.
- Combine SDK and dashboard bulk actions docs
- Fix API reference pages for bulk actions
- Fix weird rendering on bulk actions page
## Todo
- [ ] not sure about having the SDK+dashboard combined and under "Using
the dashboard"... need to find the right place
Follow-up to #4194 (v3 execution app + core-helper removal). The v3
(engine V1) is end-of-lifed and enforced off in prod, so this removes a
self-contained slice of the remaining dead v3 code while **keeping every
user-facing deprecation message** - a user still on v3 must still be
told to upgrade.
## Legacy dev websocket
`app/v3/handleWebsockets.server.ts` backs the `/ws` transport used
**only** by the legacy v3 `trigger dev` CLI (v4 dev uses a different
transport). It's now authenticate-then-close with
`V3_DEV_DEPRECATION_MESSAGE`, so an old CLI is still told what to do -
only the legacy `AuthenticatedSocketConnection` / `DevQueueConsumer`
execution behind it (which can no longer run) is removed.
- Deleted `app/v3/authenticatedSocketConnection.server.ts` (its only
consumer).
- `engineDeprecation.server.ts` and the deprecation message constants
are untouched.
## Docs
Deleted the intentionally-legacy "Docker (legacy)" self-hosting page
(`open-source-self-hosting.mdx`) and redirected
`/open-source-self-hosting` (+ the existing
`/v3/open-source-self-hosting` alias) to `/self-hosting/overview`;
repointed the two inbound links. The current `self-hosting/*` docs
already describe the v4 (single supervisor) setup.
## Deliberately out of scope
Despite the branch name, this PR does **not** touch MarQS or the
socket.io coordinator/provider namespaces. Investigation found MarQS is
entangled with **live v2** queue/metrics/concurrency/project-cleanup
code (`runQueue`, `queueSizeLimits`, `taskRunConcurrencyTracker`,
`EnvironmentQueuePresenter`, `registerProjectMetrics`, `deleteProject`),
so it needs a per-file reviewed pass, not a bulk delete. That remainder
stays on TRI-11883.
refs TRI-11883
## What
Adds a new Example projects page: **ClickHouse chat agent** — a
`chat.agent()` that answers questions about your data by writing and
running SQL against ClickHouse Cloud via the official Node.js ClickHouse
client.
The page follows the existing example-project format (overview,
features, GitHub repo card, how-it-works with code excerpts, relevant
code links) and is registered in `docs.json` in alphabetical order.
## Note
The GitHub repo card links to
`triggerdotdev/examples/tree/main/clickhouse-chat-agent`, which lands in
a companion examples PR — merge that one first.
🤖 Generated with [Claude Code](https://claude.com/claude-code)
New `/billing-limits` page covering the full [billing limits
feature](https://trigger.dev/changelog/billing-limits) : the three limit
options (plan / custom / no limit), billing alerts (% of limit or dollar
thresholds), what happens when the limit is reached, the recovery flow,
the soft-limits caveat, and the billing limit marker on the Usage page.
## Summary
Adds SDK and API support for run bulk actions. You can now create bulk
cancel or replay actions from `@trigger.dev/sdk` using run IDs or the
same filters as `runs.list()`, then retrieve, list, poll, or abort the
action by its `bulk_` handle.
Tests, docs, changesets added.
## Design
The dashboard bulk action service now accepts structured filters instead
of reading directly from a dashboard request, so the dashboard and API
share the same creation path. Replay actions created through the API are
attributed with the existing `api` trigger source, while
dashboard-created actions keep `dashboard`.
The SDK exposes the new surface under `runs.bulk.*`, including
`targetRegion` for replay region overrides and cursor pagination for
listing bulk actions.
## Filters and runIds
Nuance on filters. If `filter` is provided, it MUST have at least one
key. This is to remove the footgun of passing no filter and selecting
all runs.
```typescript
{ action: "cancel", runIds: ["run_1"] } // valid
{ action: "cancel", runIds: [] } // invalid, min(1)
{ action: "cancel", filter: { status: "FAILED" } } // valid
{ action: "cancel", filter: {} } // invalid
{ action: "cancel", filter: {}, runIds: ["run_1"] } // invalid
```

[https://triggerdev.featurebase.app/p/isolated-dev-sessions-for-multiple-local-trigger-dev-instances](https://triggerdev.featurebase.app/p/isolated-dev-sessions-for-multiple-local-trigger-dev-instances)
### Feature notes:
- CLI `trigger dev` works as before
- `trigger dev --branch my-branch` to create a new branch and run
against it.
- `trigger dev archive --branch my-branch` to archive (or in webapp).
- New webapp page to manage and archive dev branches, currently feature
flagged.
### Implementation details:
- No changes to data model, no backfill. `isBranchableEnvironment`
column is ignored for dev branches, we use `parentEnvironmentId IS NULL`
instead.
- `x-trigger-branch` overloaded for preview and dev branches
- New `TRIGGER_DEV_BRANCH` env var available locally.
`TRIGGER_PREVIEW_BRANCH` overloaded for child runs.
- Lots of new glue code to sanitise the branch checks.
### Rollout
- Deploy webapp/API changes (all backwards compatible)
- Manual tests on some orgs
- Deploy docs, release CLI, flip feature flag for webapp feature
### NB
- `api.v1.projects.$projectRef.environments.ts` will return
`isBranchableEnvironment: true` for all dev environments.
### Prerequisites
- [x] Typecheck will not pass until we make a new release of
`@trigger.dev/platform` and bump it here
## Summary
Adds an environment-scoped HTTP API over the Errors feature, mirroring
the runs API. Task-run failures are grouped by a fingerprint into "error
groups," and this exposes everything you can do with them in the
dashboard:
- `GET /api/v1/errors` lists error groups, with
`filter[taskIdentifier]`, `filter[version]`, `filter[status]`
(`unresolved`/`resolved`/`ignored`), `filter[search]`, a time range, and
cursor pagination.
- `GET /api/v1/errors/{errorId}` retrieves a single group (summary,
lifecycle state, affected versions).
- `POST /api/v1/errors/{errorId}/{resolve,ignore,unresolve}` changes its
state.
- `GET /api/v1/runs?filter[error]={errorId}` lists the runs behind a
group.
Request and response schemas are exported from `@trigger.dev/core/v3` so
the SDK can reuse them, and all endpoints are documented in the API
reference (OpenAPI). `errorId` is the `error_<fingerprint>` friendly id.
## Attribution
State changes record who made them. A plain environment API key has no
user, so `resolvedBy`/`ignoredByUserId` stay null. When the caller uses
an environment JWT obtained by exchanging a personal access token or a
delegated user token at `POST /api/v1/projects/:ref/:env/jwt`, that
exchange now stamps an `act` delegation claim, and the write endpoints
read `act.sub` to attribute the change to the acting user. This is the
first endpoint to consume the `act` claim, so two small pieces of
plumbing ride along: the exchange stamps `act` for personal-access-token
subjects too (it was delegated-token-only), and the public-JWT
bearer-auth path surfaces `act.sub` to the handler.
Built on the delegated-token work in #3997.
A batch of technical-SEO fixes across the docs, all reader-facing
(titles, links, redirects):
- Canonicalize the duplicate CLI command pages: the bare `/cli-dev` and
`/cli-deploy` paths now permanently redirect to their `-commands`
equivalents, and a duplicate navigation entry is removed.
- Give the three pages that all rendered as "Overview" distinct titles
(Building with AI, self-hosting overview, Management API overview), with
sidebar labels unchanged.
- Replace the generic "Learn more" links in the introduction's
build-extension list with descriptive anchor text.
- Switch two http links to https in the Supabase guides, point a
troubleshooting page's help link to Discord, and add missing meta
descriptions to three help and troubleshooting pages.
## Summary
New `/ai-chat/prompt-caching` guide covering how to cache a chat agent's
prompt prefix with Anthropic prompt caching: the system prompt, the
conversation history (a `prepareMessages` breakpoint), and how caching
interacts with compaction. It also shows how to verify cache hits via
usage and the dashboard, the prefix-stability footguns, and an "Other
providers" section (OpenAI and Google cache automatically; Amazon
Bedrock uses `cachePoint` through `systemProviderOptions`).
Registered under Features in the AI Agents nav, next to Compaction.

## Summary
Documents the Sessions HTTP API for non-SDK and server-to-server
callers, which until now appeared only in the conceptual
[ai-chat/sessions](https://trigger.dev/docs/ai-chat/sessions) page.
## What's covered
- **Sessions API reference** —
`create`/`list`/`retrieve`/`update`/`close` added to the OpenAPI spec
and a new "Sessions API" group (`management/sessions/*`), mirroring the
Runs API.
- **Channel endpoints** — a reference page for the `.in`/`.out` realtime
HTTP endpoints (append, SSE read, records drain), the wire protocol,
`Last-Event-ID` resume, and the per-direction auth boundary (`.out`
append is secret-key only).
- **Session scopes** — `read:sessions:{id}` / `write:sessions:{id}` in
the authentication docs, with the capability boundary and the 1h token
TTL.
Cross-linked with the SDK-side `ai-chat/sessions` page. Verified by
rendering each page on the Mintlify dev server.
## Summary
Documents the two lower-level chat backend APIs and restructures the
Building agents section so it has a sane reading order.
**Custom agents page.** `chat.customAgent()` was effectively
undocumented (one passing mention) and `chat.createSession()` was buried
at the bottom of the Backend page, prompted by a customer asking whether
dropping down a level was supported at all. Both now live on one
dedicated page framed as a composition: register with `customAgent`,
then drive turns with the managed `createSession` iterator or a
hand-rolled primitives loop. The page covers the patterns the managed
lifecycle otherwise handles for you, each verified against a running
agent: seeding history on continuation runs (and why the seed must go
through the turn-0 `addIncoming`, which replaces the accumulator),
persisting the user message before streaming so a mid-stream reload
keeps it, racing `totalUsage` after a stop so the loop cannot wedge, and
the single-message wire shape.
**Backend page.** Now leads with a decision table across the three
abstraction levels and focuses on `chat.agent()`, routing to the new
page. Stale examples that read a plural `messages` field off the wire
payload are fixed (copy-pasting them broke turn accumulation), and the
ChatSessionOptions / ChatTurn reference tables gain their missing rows
(`compaction`, `pendingMessages`, usage fields, `setMessages`,
`prepareStep`).
**Anatomy page + reorder.** The Building agents group opened with the
long How it works mechanics page, a wall right after the Quick Start. A
short Anatomy page now leads the group: the three moving parts, one
annotated example where each region names the page that covers it, and a
routing table. How it works moves to the end of the group as the depth
payoff, matching where peer docs put their internals pages.
All pages visually verified against a local Mintlify build; cross-links
and anchors updated across the section.
## Summary
Docs follow-up for #3683 (`TriggerClient` for per-instance SDK
configuration). Adds a dedicated reference page and threads the new
pattern through the existing management + preview-branches docs.
## What's in
**New page** `docs/management/multiple-clients.mdx` — when to use
`TriggerClient` vs `configure()` vs `auth.withAuth`, env-var fallback
rules, isolation contract, namespace surface, `inheritContext` opt-in,
and a when-to-use-what table.
**Updated pages**
- `docs/management/authentication.mdx` — rewrote the `auth.withAuth`
section to reflect the now-ALS-backed semantics (the prior version
warned about concurrency races and pointed at issue #3298 as a tracked
fix; that fix landed in #3683). Added `tr_preview_*` to the key prefix
list. Reframed the multi-target use case to lead with `TriggerClient`,
with `auth.withAuth` as the temporary-override helper.
- `docs/management/overview.mdx` — added a `Multiple clients in one
process` subsection.
- `docs/deployment/preview-branches.mdx` — added a `Triggering across
multiple branches from one process` example.
- `docs/triggering.mdx` — one-liner pointing at the new page for
cross-project triggering.
- `docs/docs.json` — slotted `management/multiple-clients` into the
Management API nav, right after authentication.
Paired with #3683.
## Test plan
- [ ] Mintlify preview renders cleanly
- [ ] Code samples in each updated page run as documented
- [ ] Cross-page links resolve (`/management/multiple-clients`,
`/management/authentication`)
## Summary
A new guide for connecting a database to your tasks: where to create the
client, how to size the connection pool against your provider's limit,
when to reach for a pooler, and how to release connections at waits so
you don't hit "too many connections" or crash on resume.
It covers node-postgres, Prisma, Drizzle, and MongoDB, with researched
direct and pooled connection limits for the common Postgres providers
(Supabase, Neon, RDS, PlanetScale) and MongoDB Atlas. The page lives
under Documentation, Troubleshooting, and is linked from the chat agent
docs (overview, lifecycle hooks, chat.local, and the database
persistence pattern).
## Summary
Documents the new `tools` option on `chat.agent` (companion to #3790).
Adds a dedicated [Tools](/ai-chat/tools) guide: the three places tools
show up (config, `toStreamTextOptions`, `streamText`), why declaring
them on the config matters for `toModelOutput` across turns, static vs
per-turn tools, the typed `run()` payload,
`InferChatUIMessageFromTools`, the relationship to skills, and the
manual `convertToModelMessages` path for `customAgent` loops.
Threads the option through the rest of the guide: the reference tables,
a happy-path section on the backend page, the types page, and the HITL /
skills / tool-result-auditing patterns. Corrects the sub-agents guide,
where the `toModelOutput` compression was implied to work across turns
but silently degraded from turn 2 without config tools.
Also unstacks the three callouts that were piled under the
`chat.agent()` header on the backend page, and adds a changelog entry.
## Summary
Lands the full AI Agents documentation surface alongside the v4.5
release candidate of `@trigger.dev/sdk`. Covers `chat.agent` end to end
— defining agents, lifecycle hooks, the frontend transport, sub-agents,
recovery from cancel/crash/OOM, AI Prompts integration — and the
Sessions primitive that backs it.
## Coverage
- **Conceptual**: Overview, Quick Start, How it works.
- **Building agents**: Backend (`chat.agent` / `chat.createSession` /
raw primitives), Lifecycle hooks, Frontend transport, Server-side
`AgentChat`, Sessions reference, `chat.local` state primitive,
TypeScript types.
- **Features**: AI Prompts integration, Fast starts (Preload + Head
Start), Compaction, Pending Messages (steering), Background Injection
(`chat.inject` + `chat.defer`), Actions (undo / regenerate / edit),
Error handling.
- **Patterns (13)**: Sub-agents, Branching conversations, Code sandbox,
Database persistence, Persistence and replay, HITL, Tool result
auditing, Large payloads, Agent skills, OOM resilience, Recovery boot,
Trusted edge signals, Version upgrades.
- **Reference**: API Reference, Client Protocol (wire format), Testing
harness (`mockChatAgent`), MCP server tools, Upgrade guide, Changelog.
## Structure changes
- Top-level nav: AI → **Agents**, with sub-groups for *Building agents /
Features / Patterns / Reference*.
- New RC banner snippet on every page links to the supported AI SDK
versions table on the API Reference.
- All examples use Anthropic with `stopWhen: stepCountIs(15)`.

* Add manual monorepo setup guide for Trigger.dev
This commit introduces a new "Manual setup" guide for setting up Trigger.dev in projects, specifically focused on monorepo configurations. The guide outlines two primary approaches for monorepos: creating a dedicated tasks package and integrating tasks directly within apps. This detailed documentation aims to help developers manually configure their projects, bypassing automated steps, and understanding the setup better.
- Provides step-by-step instructions for both 'Tasks as a package' and 'Tasks in apps' approaches.
- Includes example configurations for various package managers, environment setups, and runtime options.
- Enhances user understanding of Trigger.dev's configuration requirements in complex monorepo environments.
The purpose of adding this guide is to enable developers to seamlessly integrate Trigger.dev into their monorepos, whether they choose to abstract tasks into packages or embed them within individual applications. This flexibility supports diverse project structures while maintaining consistency with Trigger.dev's operational prerequisites.
* Correct tasks usage in documentation
The 'tasks as package' section in the documentation had an incorrect example under 'Use tasks in your apps' which needed correction to align with the actual package usage.
- Fixed incorrect import of tasks by updating to the correct import from '@repo/tasks/trigger'.
- Updated the syntax to use 'tasks.trigger' with type parameters, following the new pattern established for triggering tasks with TypeScript.
- Added error handling to catch and log errors during task execution, returning a meaningful error message instead of just failing silently.
This update ensures developers have an accurate reference when implementing tasks in their applications, especially given the breaking changes in TypeScript compatibility due to recent package updates.
* Update package configuration for Zod 3-4 compatibility
The recent Zod package updates from version 3 to 4 introduce breaking changes in TypeScript compatibility that require adjustments in our project configuration files. The primary updates involve adding type annotations and modifying import statements to support the shift without breaking existing functionality.
- Updated `package.json` and initialization files to align with new compatibility requirements.
- Modified server task examples to explicitly use type imports for improved error handling and consistency.
- Adjusted workspace and project settings to maintain compatibility and improve configuration clarity.
- Provided references to current examples for better implementation guidance.
* More manual setup guide steps
* Fix bun docs link
