The `/archive` and `/desktop` chat endpoints had swagger route comments
(`@Summary`, `@ID`, `@Router`, etc.) that would cause them to appear in
generated API docs. Since these live under `/experimental/chats`, they
should not be documented.
This removes the swagger annotations and adds the standard `//
EXPERIMENTAL: this endpoint is experimental and is subject to change.`
comment to `archiveChat` (the `watchChatDesktop` handler already had it,
just needed the swagger block removed).
Adds `docs/ai-coder/agents/chat-api.md` — a concise guide for the
experimental `/api/experimental/chats` endpoints.
**What's included:**
- Authentication
- Quick start curl example
- Core workflow (create → stream → follow-up)
- All major endpoints: create, messages, stream, list, get, archive,
interrupt
- File uploads
- Chat status reference
Also marks all Coder Agents child pages as `early access` in
`docs/manifest.json`.
The release calendar was outdated — it still showed v2.30 as Mainline
and v2.31 as Not Released.
This runs the `scripts/update-release-calendar.sh` script and manually
re-adds the ESR rows that the script doesn't handle:
**Changes:**
- v2.28: Security Support → Not Supported
- v2.29: Stable + ESR → Security Support + ESR (v2.29.8)
- v2.30: Mainline → Stable (v2.30.3)
- v2.31: Not Released → Mainline (v2.31.5)
- Added 2.32 as Not Released
- Kept 2.24 as Extended Support Release
- Updated latest patch versions for all releases
- Removed 2.25 (no longer in the rolling window)

Adds a new **Enable Coder Agents** section to the Early Access doc
explaining how to activate the `agents` experiment flag via
`CODER_EXPERIMENTS` or `--experiments`.
## Changes
### `docs/ai-coder/agents/early-access.md`
- New **Enable Coder Agents** section with env var and CLI flag
examples.
- Note that the `agents` flag is excluded from wildcard (`*`) opt-in.
- Quick-start checklist: dashboard → Admin → configure provider/model →
start chatting.
- Link to GitHub issues for feedback.
### `docs/ai-coder/agents/index.md`
- Updated **Product status** from "internal preview" to "Early Access"
with a link to the early-access page for enablement instructions.
Restore PR title validation that was removed in 828f33a when
cdr-bot was expected to handle it. That bot has since been disabled.
The new title job in contrib.yaml validates:
- Conventional commit format (type(scope): description)
- Type from the same set used by release notes generation
- Scope validity derived from the changed files in the PR diff
- All changed files fall under the declared scope
Uses actions/github-script (no third-party marketplace actions).
Also fixes feat(api) examples across docs (no api folder exists)
and consolidates commit rules into CONTRIBUTING.md as the single
source of truth.
This PR adds a `WatchAllWorkspaces` function with `watch-all-workspaces`
endpoint, which can be used to listen on a single global pubsub channel
for _all_ workspace build updates, and makes use of it in the autostart
scaletest.
This negates the need to use a workspace watch pubsub channel _per_
workspace, which has auth overhead associated with each call. This is
especially relevant in situations such as the autostart scaletest, where
we need to start/stop a set of workspaces before we can configure their
autostart config. The overhead associated with all the watch requests
skews the scaletest results and makes it harder to reason about the
performance of the autostart feature itself.
The autostart scaletest also no longer generates its own metrics nor
does it wait for all the workspaces to actually start via autostart. We
should update the scaletest dashboard after both PRs are merged to
measure autostart performance via the new metrics.
The new function/endpoint and its usage in the autostart scaletest are
gated behind an experiment feature flag, this is something we should
discuss whether we want to enable the endpoint in prod by default or
not. If so, we can remove the experiment.

Implement the backend for the desktop feature for agents.
- Adds a new `/api/experimental/chats/$id/desktop` endpoint to coderd
which exposes a VNC stream from a
[portabledesktop](https://github.com/coder/portabledesktop) process
running inside the workspace
- Adds a new `spawn_computer_use_agent` tool to chatd, which spawns a
subagent that has access to the `computer` tool which lets it interact
with the `portabledesktop` process running inside the workspace
- Adds the plumbing to make the above possible
There's a follow up frontend PR here:
https://github.com/coder/coder/pull/23006
Add cost tracking for LLM chat interactions with microdollar precision.
## Changes
- Add `chatcost` package for per-message cost calculation using
`shopspring/decimal` for intermediate arithmetic
- **Ceil rounding policy**: fractional micros round UP to next whole
micro (applied once after summing all components)
- Database migration: `total_cost_micros` BIGINT column with historical
backfill and `created_at` index
- API endpoints: per-user cost summary and admin rollup under
`/api/experimental/chats/cost/`
- SDK types: `ChatCostSummary`, `ChatCostModelBreakdown`,
`ChatCostUserRollup`
- Fix `modeloptionsgen` to handle `decimal.Decimal` as opaque numeric
type
- Update frontend pricing test fixtures for string decimal types
## Design decisions
- `NULL` = unpriced (no matching model config), `0` = free
- Reasoning tokens included in output tokens (no double-counting)
- Integer microdollars (BIGINT) for storage and API responses
- Price config uses `decimal.Decimal` for exact parsing; totals use
`int64`
Frontend: #23037
_Disclaimer: implemented by a Coder Agent using Claude Opus 4.6._
Marks the injected MCP approach in AI Bridge as deprecated across the
codebase.
## Changes
- **`codersdk/deployment.go`**: Deprecated `ExternalAuthConfig.MCPURL`,
`.MCPToolAllowRegex`, `.MCPToolDenyRegex` fields; deprecated and hid the
`--aibridge-inject-coder-mcp-tools` server flag; deprecated
`AIBridgeConfig.InjectCoderMCPTools`.
- **`coderd/externalauth/externalauth.go`**: Deprecated `Config.MCPURL`,
`.MCPToolAllowRegex`, `.MCPToolDenyRegex`.
- **`enterprise/aibridgedserver/aibridgedserver.go`**: Added runtime
deprecation warning when `CODER_AIBRIDGE_INJECT_CODER_MCP_TOOLS` is
enabled; deprecated `getCoderMCPServerConfig`.
- **`enterprise/aibridged/mcp.go`**: Deprecated `MCPProxyBuilder`
interface and `MCPProxyFactory` struct.
- **`docs/ai-coder/ai-bridge/mcp.md`**: Added deprecation warning
banner.
WaitBuffer is a thread-safe io.Writer that supports blocking until
accumulated output matches a substring or custom predicate. It
replaces ad-hoc safeBuffer/syncWriter types and time.Sleep-based
poll loops in tests with signal-driven waits.
- WaitFor/WaitForNth/WaitForCond for blocking on output
- Replace custom buffer types in cli/sync_test.go and
provisionersdk/agent_test.go
- Convert time.Sleep poll loops to require.Eventually/require.Never
in cli/ssh_test.go, coderd/activitybump_test.go,
coderd/workspaceagentsrpc_test.go, workspaceproxy_test.go, and
scaletest tests
The pre-push hook was removed in #22956. This restores it with a
reduced scope (tests + site build) and an allowlist so it only runs
for developers who opt in.
Two opt-in mechanisms:
- git config coder.pre-push true (local, not committed)
- CODER_WORKSPACE_OWNER_NAME allowlist in the hook script
git config takes priority and also supports explicit opt-out for
allowlisted users (git config coder.pre-push false).

placeholders
- apply default pricing when admins leave pricing fields blank
## Summary
- remove the `pre-push` git hook script from the repository
- remove the `make pre-push` target and related Makefile documentation
- update contributor and agent docs so they only describe the remaining
`pre-commit` hook
## Validation
- `make pre-commit`
- `git diff --check`

## Changes
- Add `"state": ["early access"]` to all child pages under Coder Agents
in `docs/manifest.json` (Architecture, Models, Platform Controls, Early
Access).
- Point the Coder Agents video `<source>` directly at
`raw.githubusercontent.com` instead of the `github.com/blob/` URL with
`?raw=true`.
The chat API is experimental (behind `ExperimentAgents`) and not ready
for public documentation yet. This removes swagger annotations from the
chat handlers so they no longer appear in the generated API reference at
https://coder.com/docs/reference/api/chats.
## Changes
- Remove `@swagger` annotations from 5 chat handlers in
`coderd/chats.go`
- Regenerate `coderd/apidoc/swagger.json` and `docs.go`
- Delete `docs/reference/api/chats.md`
- Remove Chats entry from `docs/manifest.json`
Adds a new child page at `/docs/ai-coder/agents/early-access` describing
the Coder Agents Early Access, including what it includes, what it does
not include, feature scope, licensing, and how to provide feedback.
The codex registry module v4.2.0 wires `enable_state_persistence`
through to agentapi, completing session resume support. Combined with
the `--type codex` flag added in v4.1.2, Codex now fully preserves
conversation context across pause and resume cycles.

This change adds support for image attachments to chat via add button
and clipboard paste. Files are stored in a new `chat_files` table and
referenced by ID in message content. File data is resolved from storage
at LLM dispatch time, keeping the message content column small.
Upload validates MIME types via content type or content sniffing against
an allowlist (png, jpeg, gif, webp). The retrieval endpoint serves files
with immutable caching headers. On the frontend, uploads start eagerly
on attach with a background fetch to pre-warm the browser HTTP cache so
the timeline renders instantly after send.
This change adds git hooks and Makefile targets that mirror CI required
checks locally, catching issues before they reach CI.
This is for use by AI agents (documented in AGENTS.md).
- **pre-commit** (every commit): gen, fmt, lint, typos, slim binary
build. Fast checks without Docker or Playwright.
- **pre-push** (before push): full CI suite including site build, tests,
sqlc-vet, offlinedocs.
To use:
```sh
git config core.hooksPath scripts/githooks
```
Works in worktrees (where `.git` is a file). Bypass with `--no-verify`.
Adds real-time git status watching for workspace agents, so the frontend
can subscribe over WebSocket and show
git file changes in near real-time.
1. Subscription is scoped to a **chat** via `GET
/api/experimental/chats/{chat}/git/watch`.
2. The workspace agent automatically determines which paths to watch
based on tool calls made by the chat (and its ancestor chats).
3. Workspace agent polls subscribed repo working trees on a 30s
interval, on tools calls, and on explicit `refresh` from the client.
4. Scans are rate-limited to at most once per second.
5. Edited paths are tracked **in-memory** inside the workspace agent.
There is no database persistence — state is lost on agent restart. This
will be addresses in a future PR.
6. Messages sent over WebSocket include a full-repo snapshot (unified
diff, branch, origin). A new message is emitted only when the snapshot
changes.
This PR was implemented with AI with me closely controlling what it's
doing. The code follows a plan file that was updated continuously during
implementation. Here's the file if you'd like to see it:
[project.md](https://gist.github.com/hugodutka/8722cf80c92f8a56555f7bc595b770e2).
It reflects the current state of the PR.
This PR does three things:
- Exports derp expvars to the pprof endpoint
- Exports the expvar metrics as prometheus metrics in both coderd and
wsproxy
- Updates our tailscale to a fix I also had to make to avoid a data race
condition
I generated this with mux but I also manually tested that the metrics
were getting properly emitted
Adds a docs page under /docs/ai-coder/agents describing our philosophy
on platform team control over agent behavior: admin-level configuration,
zero developer options, enforcement over defaults. Covers what's
available today (providers, models, system prompt, template routing) and
where we're headed (usage analytics, infra-level enforcement, tool
customization).
## Description
Documents the new TLS listener support for AI Bridge Proxy.
Updates `setup.md` with a new "Proxy TLS Configuration" section covering self-signed and corporate CA certificate setup, rewrites "Security Considerations" to reflect TLS as the recommended approach for encrypting client connections, and updates "Client Configuration" with `HTTPS_PROXY` defaults and combined certificate trust instructions.
Updates `copilot.md` to default all proxy URL examples to `https://`, add TLS certificate trust guidance for each client (CLI, VS Code, JetBrains), and document the MCP server trust store requirement for Copilot CLI.
Closes: https://github.com/coder/internal/issues/1335
## Description
Adds optional TLS support for the AI Bridge Proxy listener. When TLS cert and key files are provided, the proxy serves over HTTPS instead of plain HTTP.
## Changes
* New configuration options to enable TLS on the proxy listener
* Wraps the TCP listener in `tls.NewListener` when configured
* Tests for validation errors, invalid files, and full integration (tunneled + MITM) through a TLS listener
Note: Documentation for TLS listener setup and client configuration will be handled in a follow-up PR.
Related to: https://github.com/coder/internal/issues/1335
## Description
Renames internal fields, variables, and comments related to the proxy's certificate/key configuration to explicitly reference their MITM CA purpose.
The AI Bridge Proxy uses a CA certificate to sign dynamically generated leaf certificates during MITM interception of HTTPS traffic from AI clients. With the upcoming introduction of TLS listener certificates (for serving the proxy itself over HTTPS, implemented upstack https://github.com/coder/coder/pull/22411), the previous generic naming would become ambiguous. This refactor makes it clear which certificate is which.
No user-facing flags, environment variables, YAML keys, or JSON fields were changed, this is purely an internal rename to avoid confusion going forward.

Adds a new child page under **Coder Agents**
(`/docs/ai-coder/agents-architecture`) that explains how the agent in
the control plane communicates with workspaces.
## Core message
The Coder Agent interacts with workspaces using the exact same
connection path as a developer's IDE, web terminal, or SSH session — no
special protocol, no sidecar, no new ports.
## Changes
- Removed the Coder Agents entry from the middle of the children array
in `docs/manifest.json`.
- Added the Coder Agents entry back at the end of the children array to
improve the organization of the documentation structure.

Adds a new documentation page at `docs/ai-coder/agents.md` describing
Coder Agents — the built-in chat interface, API, and lightweight AI
coding agent that runs in the Coder control plane.
## What's included
- Overview of what Coder Agents is and who it's for (regulated
industries, platform teams, existing Coder deployments)
- How the architecture works (agent loop in coderd, outbound to LLM
providers, connects to workspaces via existing daemon connection)
- Key features: automatic template/workspace selection, sub-agents, chat
persistence, message queuing
- Security benefits of the control plane architecture (no API keys in
workspaces, simpler network boundaries, centralized enforced control,
user identity attached)
- LLM provider support table (verified against
`coderd/chatd/chatprovider/chatprovider.go`)
- Built-in tools reference
- Comparison to Coder Tasks
- Product status (internal preview, early access next)

# Summary
This PR resolves a flaky test that was sensitive to DST transitions in
various time zones. The root of the flake was:
* a bug; the query and its tests assume 24 hours per day
* the tests used local system time, which resulted in failures for dates
proximal to DST transitions
# Changes
Query:
The original query assumed 24 hour intervals between each day, which is
not a valid assumption. It now increments `1 day` at a time.
Database tests:
Database level tests for the query all assumed 24 hour days. They now
increment in DST-aware days instead. Instead of using time.Now() as a
base for testing, the test uses a series of dates over the course of an
entire year, to ensure that DST transition dates are present in every
test run.
# API Endpoint
The endpoint that delivers the user status chart now accepts an IANA
timezone name as a parameter and passes it, keeping the existing offset
as a fallback, to the database query.
API level tests were added to ensure the correct response form and error
behaviour. Correctness of content is tested at the database level.
Add Prometheus metrics to the boundary log proxy for observability:
- batches_dropped_total (reason: buffer_full, forward_failed)
- logs_dropped_total (reason: buffer_full, forward_failed,
boundary_channel_full, boundary_batch_full)
- batches_forwarded_total
Also add BoundaryStatus to the BoundaryMessage envelope so boundary
can report dropped log counts as a separate wire message. The agent
records these as Prometheus metrics, making boundary-side data loss
visible. Backwards compatibility for older versions of boundary is maintained.

relates to #21335
Enables the agent socket by default and updates docs to strike references to having to enable it.
The PRs in this stack change the MCP server that Tasks use to update their status to rely on the agent socket, rather than directly dialing Coderd with the agent token.
Default disable was a reasonable default when it was only used for the experimental script ordering features, but now that we want to use it for Tasks, it should be default on.
The pause/resume endpoints were only registered under /api/experimental
but the frontend and Go SDK were calling /api/v2, resulting in 404s.
Register the routes in the v2 group, update the SDK client paths, and
fix swagger annotations (Accept → Produce) since these POST endpoints
have no request body.
This pull-request follows up #22060
Felt wrong to only make use of Geist when there is a Monospace variant
here too. Felt best we default to this as the default font as its inline
with the rest of the application. This also updates the lower line for
Workspace Statistics 🙂
## Summary
The UI has always labeled the action as "Archive agent" but the backend
was performing a hard `DELETE`, permanently destroying chats and all
their messages.
This change replaces the hard delete with a soft archive, consistent
with the pattern used by template versions.
## Changes
### Database
- **Migration 000423**: Add `archived boolean DEFAULT false NOT NULL`
column to `chats` table
- Replace `DeleteChatByID` query with `ArchiveChatByID` (`UPDATE SET
archived = true`)
- Add `UnarchiveChatByID` query (`UPDATE SET archived = false`)
- Filter archived chats from `GetChatsByOwnerID` (`WHERE archived =
false`)
### API
- Remove `DELETE /api/experimental/chats/{chat}`
- Add `POST /api/experimental/chats/{chat}/archive` — archives a chat
and all its descendants
- Add `POST /api/experimental/chats/{chat}/unarchive` — unarchives a
single chat (API only, no UI yet)
### Backend
- `archiveChatTree()` recursively archives child chats (replaces
`deleteChatTree()` which hard-deleted)
- Chat daemon's `ArchiveChat()` archives the full chat tree in a
transaction
- Authorization uses `ActionUpdate` instead of `ActionDelete`
### SDK
- Replace `DeleteChat()` with `ArchiveChat()` and `UnarchiveChat()`
- Add `Archived` field to `Chat` struct
### Frontend
- `archiveChat` API call uses `POST .../archive` instead of `DELETE`
- No UI changes — the "Archive agent" button now actually archives
instead of deleting
## Design Decision
This follows the **template version archive pattern** (Pattern B in the
codebase):
- `archived boolean` column (not `deleted boolean`)
- Dedicated `POST .../archive` and `POST .../unarchive` routes (not
repurposing `DELETE`)
- Reversible — users can unarchive via the API (UI for this will come
later)
