Michael Suchacz 8eb1e43f0b feat: apply reasoning effort and surface thinking blocks for Google chat models (#28273)
## Problem

Selecting a reasoning effort on a Google (Gemini) chat model either got
dropped or broke the request outright, and even when the request
succeeded, Gemini chats never showed thinking blocks:

- The native `fantasygoogle` path had no case in `applyReasoningEffort`
at all, so effort was silently ignored. With only `include_thoughts`
configured, Gemini 3+ models default to no thinking, so chats produced
zero reasoning tokens.
- The path chat generation actually uses today routes Google providers
through aibridge as openai-compat clients and forwarded the raw effort
string as `reasoning_effort`. Google's OpenAI-compatible endpoint
validates that value against the model's supported thinking levels
instead of clamping, so out-of-range efforts fail the whole request with
HTTP 400. Verified against the live Gemini API: `gemini-3.1-pro-preview`
accepts low/medium/high and rejects none/minimal/xhigh/max. Because the
config's default effort is sent whenever the user selects nothing, a
config whose default falls outside the model's supported set failed
every no-selection message.
- Google's OpenAI-compatible endpoint never emits thought text for
`reasoning_effort` requests. Thoughts require
`extra_body.google.thinking_config` with `include_thoughts`, which is
mutually exclusive with `reasoning_effort`, and even then the thought
deltas come back inline in `content` (marked
`extra_content.google.thought`, wrapped in `<thought>` markers) rather
than in the `reasoning_content` field OpenAI-compatible clients parse.
So no reasoning parts were ever produced, persisted, or rendered for
Gemini chats (verified live in UAT).

## Fix

Reasoning effort:

- Map the global reasoning effort scale onto Google's `thinking_level`
in `applyReasoningEffort`, gated to Gemini 3+ models and clamped to each
model's supported subset (3.0 Pro launched with LOW/HIGH only, 3.1 Pro
added MEDIUM, Flash accepts all four through 3.6 while 3.7 and the
latest flash aliases drop MINIMAL, image models accept HIGH plus MINIMAL
for flash). Pre-Gemini-3 models reject `thinking_level`, so effort
degrades to a no-op for them and a config-pinned level is dropped at
call time instead of failing every generation.
- Add `thinking_level` to `ChatModelGoogleThinkingConfig` so admins can
pin a level for configs without user-selectable effort. A resolved
per-turn effort overrides the pinned level; an explicit
`thinking_budget` wins over both since the Google API rejects requests
that set `thinking_budget` and `thinking_level` together, and config
validation now rejects that combination up front. The admin panel picks
up the new field automatically through the generated model-options
schema.

Thinking blocks on the openai-compat path (the path chat generation
uses), translated in both directions at the existing Gemini transport
seam:

- chatd's OpenAI-compat request patch swaps `reasoning_effort` for an
equivalent `extra_body.google.thinking_config` with `include_thoughts`
enabled: `thinking_level` on Gemini 3+ (clamped to the model's supported
subset), `thinking_budget` on earlier models (effort `none` maps to
budget 0, which disables thinking). Non-Gemini models and non-Google
routes are untouched.
- The same transport rewrites Google's responses so thought output
surfaces as `reasoning_content`, which fantasy already converts into
reasoning parts: streaming bodies are rewritten per SSE line (preserving
streaming latency), JSON bodies in place, with the
`<thought>`/`</thought>` markers stripped at the transitions.
- aibridge's chat-completions interception preserves the `extra_body`
passthrough that openai-go's typed params silently drop, forwarding it
to Google upstreams only, so the chatd -> aibridge -> Google route
carries the thinking config end to end.

## Validation

- `go test ./coderd/x/chatd/... ./aibridge/... ./internal/googleopenai
./codersdk` pass; golangci-lint clean on touched packages.
- New unit tests cover the effort-to-level mapping for every effort
value, per-model clamping on both paths, the effort-to-thinking_config
request swap (level, budget, pinned-config precedence, non-Gemini
passthrough), SSE and JSON thought-response rewriting (fixtures mirror
live captures, including tool-call and no-thought streams), an
end-to-end fake-SSE test through the fantasy pipeline proving reasoning
deltas emerge with markers stripped, and aibridge `extra_body`
preservation (including proof the typed round trip drops it).
- Verified live against `generativelanguage.googleapis.com` on
`gemini-3-flash-preview` and `gemini-2.5-flash` through the real
chatprovider stack: reasoning deltas stream through with markers
stripped and answer text intact.
- Live UAT on a dogfood deployment (remote Coder Agents chat, 4 rounds):
effort clamping verified end to end (rounds 1-2), the missing-thoughts
limitation isolated (round 3), and the fix validated (round 4):
expandable, readable thinking blocks render for
`gemini-3.1-pro-preview`, `gemini-3-flash-preview`, and
`gemini-2.5-flash` at effort=high; no `<thought>` marker leaks;
effort=none produces no block and no 400; multi-turn history replay
works with a thinking block on each turn.
- `make gen` regenerated `typesGenerated.ts` and
`chatModelOptionsGenerated.json`; `pnpm -C site lint:types` passes.

Susana Ferreira 50ecd6959f feat: add a source filter to the AI model price list (#28329)
## Description

With prices from the price book and prices set through the API both in the table, `list` showed only the price in effect and gave no way to tell where it came from. There was also no way to see the price book's entry for a model that had been overridden, since the listing resolves to the custom price.

This adds a `source` column to the output and a `--source` filter for narrowing to one source, or to every row with `all`.

Note: `--source` selects rows rather than models. A model carrying both a price book price and a custom one appears under either value, so the two filtered listings do not sum to the unfiltered one. `--source all` reports both rows at once.

## Changes

- Add `Source` to `codersdk.AIModelPrice` and `AIModelPricesFilter`, and map it in `db2sdk`, which previously dropped it.
- Filter `GetAIModelPrices` by source before resolution, so the price book's row for an overridden model stays reachable.
- Accept `all` as a source, which reports every price a model holds instead of resolving to one.
- Accept a `source` query parameter on the list endpoint, rejected with a 400 when outside the enum.
- Add `--source` to the list command and a `source` column to its output.
- Document the column and the filter, and lead the price section with `coder exp ai-model-prices list`.
- Distinguish a deployment's default prices from the price book that ships with each release.

Michael Suchacz 2f996d765a feat: remove task management MCP tools (#28354)
Removes the six task-management tools from the MCP tool surface in
`codersdk/toolsdk`:

- `coder_create_task`
- `coder_delete_task`
- `coder_list_tasks`
- `coder_get_task_status`
- `coder_send_task_input`
- `coder_get_task_logs`

Both the coderd-hosted MCP server (`coderd/mcp`) and the CLI `coder exp
mcp server` derive their tool list from `toolsdk.All`, so removing the
registry entries removes the tools from both servers with no server-side
changes.

The MCP server documentation (`docs/ai-coder/mcp-server.md`) is updated
to drop the task-management entry from the tool overview.

## What stays

- `coder_report_task` is intentionally kept: it is the agent-side
status-reporting mechanism (`WithTaskReporter`), already excluded from
the hosted MCP server, and required by `coder exp mcp server`, Claude
Code configuration, and scaletest.
- The `codersdk` Task SDK methods (`CreateTask`, `DeleteTask`, `Tasks`,
`TaskLogs`, etc.) and the Tasks feature (CLI, UI, API) are untouched;
this PR only removes MCP tool registration.
- The task-only `taskIDDescription` helper is deleted; `userDescription`
stays (used by `coder_create_workspace`).

The code change is deletion-only: 970 removed lines across `toolsdk.go`
and its test file, no added behavior.

## Validation

- `go build ./...`, `go test ./coderd/mcp/`, and targeted
`golangci-lint` pass. `go test ./codersdk/toolsdk/` passes all tests;
the package-level goleak failure (agentssh goroutines) reproduces
identically on unmodified `main` and is unrelated to this diff.
- `pnpm run lint-docs` passes on the docs change.
- Remote dogfood UAT ran against the toolsdk change and passed:
`tools/list` on both the hosted MCP endpoint and `coder exp mcp server`
confirms the six tools are absent and the remaining surface is intact
(34 hosted tools; CLI adds `search`/`fetch`), a `tools/call` of
`coder_get_authenticated_user` succeeds, and calling a removed tool
returns `-32602 unknown tool`. `coder_report_task` still registers in
the CLI server when `CODER_MCP_APP_STATUS_SLUG` is set.
- The failing `Pixel / Review` commit status is unrelated: this PR
contains no `site/` changes, and the same status fails on the last 8
`main` commits including this PR's merge base (`676b9bb06bf`).

Michael Suchacz 7ca7c30f40 feat: add group and user ACLs to MCP server configs (#27944)
Adds group and user ACLs to org-scoped MCP server configs so
organizations can restrict specific MCP servers to subsets of members,
mirroring the template ACL pattern.

## Summary

- Migration adds `group_acl`/`user_acl` JSONB columns (nested `{"<id>":
{"permissions": [...]}}` shape) and seeds every existing config with its
organization's Everyone group read entry (the Everyone group ID equals
the org ID), so member access is unchanged by default. Creation seeds
the same entry.
- The blanket org-member read grant from the base PR is replaced by ACL
evaluation: Rego requires org membership for every ACL grant, and
`GetAuthorizedMCPServerConfigs` compiles ACL-aware SQL filters.
- New `ActionShare` (org admins) gates `GET|PATCH
/api/experimental/organizations/{organization}/mcp-servers/{mcpserverconfig}/acl`
(nested under the organization like the rest of the config surface).
PATCH validates principals against the config's organization, merges
sparse updates under a row lock, stamps `updated_by`/`updated_at`, and
is audited as a Write with `Old` captured before authorization. A config
deleted concurrently between the middleware fetch and the locked
re-fetch is concealed as 404, matching the update and delete handlers.
ACL columns are tracked in the audit table.
- ACL management is available in all editions (no enterprise
entitlement), documented in the MCP servers page. Revoking an ACL does
not retro-strip already-selected configs from existing chats; new
selection is blocked at chat create.
- Force On respects the ACL: the forced set is loaded as the chat owner,
so a `force_on` server whose ACL denies the owner never attaches at
create, send, or generation time.
- No rolling-upgrade machinery: upgrades run in scheduled maintenance
downtime, so the migration only backfills existing rows; the API sets
the Everyone read grant explicitly on every insert.

Stacked on #27943. Part of the MCP org-separation stack.

Everyone-seed default visibility, group grant with Everyone removal
(non-member loses list/fetch/selection), foreign-principal rejection,

and audited ACL diffs.

Michael Suchacz 299e72ad30 feat: audit MCP server config changes (#27943)
Adds enterprise audit logging for MCP server config create, update, and
delete, with strict secret redaction. MCP configs hold credentials
(OAuth2 client secrets, API keys, custom headers), so admin changes to
them need an audit trail.

## Summary

- `enterprise/audit/table.go` gains an `MCPServerConfig` entry
enumerating every column: `oauth2_client_secret`, `api_key_value`, and
`custom_headers` are `ActionSecret` (never appear in diffs); dbcrypt
`*_key_id` bookkeeping, IDs, and timestamps are ignored; the remaining
config fields, including the endpoint URL fields, are tracked so
auditors can see which endpoints a config points at.
- Type registration in `coderd/audit` (diff, request, resource target
with org attribution), `codersdk/audit.go`, and a `resource_type` enum
migration.
- Handlers wire `audit.InitRequest`: create records `New`; update and
delete record `Old` from the param middleware before the
write-authorization check, so a readable-but-not-writable caller
produces an audited 403 while read-denied callers stay concealed as
unaudited 404s.
- Tests: create/update/delete audit entries, write-denied and
delete-denied 403 auditing, cross-org concealment producing zero
entries, and a serializer-level regression test proving none of the
three secret classes can reach a serialized diff.
- Review round: MCP config audit entries link to
`/ai/settings/mcp-servers/{id}`, audit table comments are trimmed per
review, and a fault-injection test pins that a config row surviving a
failed post-discovery credential update still gets its creation audit
entry.

Michael SuchaczandMathias Fredriksson 443e3b9b80 feat!: org-scope MCP server configs with RBAC (#27942)
Moves `mcp_server_configs` from deployment scope to organization scope
so each organization fully controls the MCP servers its members can use
with Coder Agents.

## Summary

- Migration: adds `organization_id` (NOT NULL, FK) and keeps existing
rows as the default organization's originals with credentials intact.
Other organizations start with no MCP servers and configure their own;
nothing is copied across organizations. Chats outside the default
organization keep any now-cross-organization `mcp_server_ids` entries;
the runtime already ignores IDs that do not resolve in the chat's
organization, so no data rewrite is needed. Slug uniqueness becomes
`(organization_id, slug)`.
- RBAC: new org-scoped `ResourceMCPServerConfig` with regosql converter
and `GetAuthorizedMCPServerConfigs`; org admins get in-org CRUD, org
members get read (replaced by ACL evaluation in the follow-up ACL PR in
this stack).
- API: all config routes nest under the organization, matching
templates: `POST|GET
/api/experimental/organizations/{organization}/mcp-servers` and
`GET|PATCH|DELETE .../mcp-servers/{mcpserverconfig}` (plus
`oauth2/connect`), resolved by a read-only param middleware that
conceals read-denied and cross-organization access as 404. Two routes
stay on the frozen `/api/experimental/mcp/servers/{mcpServer}` block:
the OAuth2 callback (the redirect URI baked into existing AS-side client
registrations) and `oauth2/disconnect`, which must remain reachable by
users removed from the organization so they can still revoke their token
grant.
- Chat runtime: selection validation and generation resolve configs
strictly by IDs, enabled state, and the chat's organization in SQL;
requested duplicates are normalized; invalid or cross-org IDs are
rejected with the precise ID list. IDs already persisted on a chat are
exempt from message-time rejection so disabling a selected server never
blocks sends; generation skips servers that are no longer usable.
- Frontend: API layer and admin settings pages target the new endpoints.
The admin page manages the default organization's servers; the org
picker is tracked separately (CODAGT-714).

- Security hardening from review: OAuth user grants are additionally
bound to `oauth2_revocation_url` (changing it invalidates grants, and a
racing OAuth callback gets 409 instead of recreating a grant).
Stack-wide SSRF protection for MCP config-directed traffic was split
into its own PR at the top of this stack (#28242) to keep this diff
reviewable; this PR keeps main's existing discovery IP-range guard.
OAuth2 auto-discovery now completes before the config row is inserted: a
failed discovery persists nothing, and there is no provisional row that
concurrent updates could race against.

Two follow-up PRs in this stack were split out to keep this diff
reviewable: #28064 completes the swagger annotations for the moved
routes (main already ships these experimental MCP handlers unannotated),
and #28065 carries hardening fixes and regression pins on top of the
cutover.

- Force On enforcement (landed on main mid-review) is org-scoped: the
forced set is read per chat organization
(`GetForcedMCPServerConfigsByOrganization`), so another organization's
`force_on` server never attaches to a chat.

## Breaking changes (experimental API)

The MCP server config endpoints move from the deployment-scoped
`/api/experimental/mcp/servers` block to organization-nested paths:
`POST|GET /api/experimental/organizations/{organization}/mcp-servers`
and `GET|PATCH|DELETE
/api/experimental/organizations/{organization}/mcp-servers/{mcpserverconfig}`
(plus `oauth2/connect`). The old paths are removed, so API consumers
must supply an organization. Two routes intentionally stay on the frozen
`/api/experimental/mcp/servers/{mcpServer}` block: the OAuth2 callback
(its redirect URI is baked into existing AS-side client registrations)
and `oauth2/disconnect` (must remain reachable by users removed from the
organization). These endpoints are under `/api/experimental`, so no
deprecation window is provided.

## Rolling upgrades

During a rolling deploy, an old replica creating an MCP config can fail
the new `NOT NULL organization_id` constraint until it is upgraded
(reads are unaffected: old binaries' generated queries select their own
column lists). This matches the repo's existing precedent for additive
NOT NULL migrations (000562) and affects only the admin config-create
path in the upgrade window.

Upgrades are expected to run in scheduled maintenance downtime with the
database locked during migration, so the migration ships no
rolling-upgrade compatibility machinery. The down migration deletes
organization-created configs (their chat references are cleaned by the
000510 delete trigger) and restores deployment-wide slug uniqueness.

Part of the MCP org-separation stack (CODAGT-711 -> CODAGT-717 audit ->
CODAGT-712 ACLs -> CODAGT-806 token RBAC).

Closes https://linear.app/codercom/issue/CODAGT-711

UAT: validated end to end on a two-org dogfood deployment, including a
real pre-migration to post-migration upgrade, cross-org isolation
(404s), same-slug-two-orgs, chat selection gating, and a live MCP tool
call through the org-scoped generation path. The migration was later
revised to keep existing rows in the default organization only (no
per-organization copies); that revision is covered by the migration test
suite.

Ben Potter 8a7e8d9d5b refactor: move chat prompt sanitization into codersdk (#28283)
Exports `SanitizePromptText` (and its helpers) from `codersdk` instead
of `coderd/x/chatd`, so API consumers can sanitize prompt text exactly
the way the server stores it.

## Why

coder/terraform-provider-coderd#412 adds a `coderd_chat_system_prompt`
resource whose `system_prompt` attribute compares values by their
sanitized forms (otherwise the trailing newline from
`file("system-prompt.md")` is perpetual drift, since the server stores
the sanitized value). That currently requires a mirrored copy of the
sanitizer in the provider, which can silently rot. Per review there
([discussion](https://github.com/coder/terraform-provider-coderd/pull/412#discussion_r3801110795)),
the sanitizer should be exported from `codersdk` and imported instead.

## What

- `coderd/x/chatd/sanitize.go` → `codersdk/promptsanitize.go` (pure
move; package + doc-comment note about why it lives in codersdk)
- `coderd/x/chatd/sanitize_test.go` → `codersdk/promptsanitize_test.go`
- Callsites updated (`exp_chats.go`, `chatd.go`, `subagent.go`,
`context_prompt.go`); no wrapper left behind, single source of truth
- No behavior change

Bobby Ho 663f41ffa9 feat: derive OAuth2 client type from token_endpoint_auth_method (#28043)
Adds an OAuth2 client type (public vs confidential, RFC 7591 §2) derived
from the requested auth method instead of hardcoded confidential. The
type is stored and guarded here, but no endpoint enforces on it yet;
public behavior at the token endpoint follows in the next PR in the
stack.

- Client type is derived once and reused by both registration and
redirect URI validation, so they can't disagree
- IsPublic() fails closed: an unrecognized or missing value reads as
confidential
- RFC 7592 update (PUT) now rejects moving a client between public and
confidential (400) instead of silently flipping it when the auth method
is omitted
- Discovery still doesn't advertise "none"; follows once the token
endpoint honors it

### Behavior by client shape

`client_type` is derived from `token_endpoint_auth_method` at POST and
pinned at PUT. RFC 7592 GET/PUT authenticate with the registration
access token, not the client secret, so neither endpoint reads a secret.

| Registered with | Stored `client_type` / method | GET reports | PUT
that flips the method |

|------------------------------------|---------------------------------------|-----------------------|-----------------------------------------|
| omitted, or `client_secret_basic` | `confidential` /
`client_secret_basic` | `client_secret_basic` | `none` → 400
`invalid_client_metadata` |
| `none` (new) | `public` / `none` | `none` | `client_secret_*` → 400
`invalid_client_metadata` |
| `none` (before this PR) | `confidential` / `none` | `none` | either →
200, type stays `confidential` |

- PUT still replaces every other RFC 7591 field. `client_type` is the
only pinned one; the method may move within a type
(`client_secret_basic` ↔ `client_secret_post`).
- Row 3 is the only shape where the two columns disagree. The guard
fires only on a method change that crosses the type line, so those
clients keep managing themselves instead of being locked out of their
own configuration endpoint.
- The token endpoint does not consult `client_type` yet, so every client
still authenticates with a secret and registration still issues one.

Jon Ayers 821d91fabd fix: log tailnet tunnel authorization decisions (#27819) 2026-08-18 18:21:50 -05:00
Mathias FredrikssonandMichael Suchacz d3f08b1983 feat: audit chat system instructions changes (#27668)
Adds an audit record for administrative events on the deployment-wide
chat instruction settings (system prompt, the include-default toggle,
and the plan-mode instructions), per CODAGT-719 and operator decision
D5. Each endpoint records under a stable identity: resource type
`chat_instruction_settings`, a fixed resource ID and a human-readable
target ("System prompt", "Plan mode instructions"), so two changes to
one setting share an ID and history-by-setting works. A real change
exports a Write entry with the old-to-new text visible; a
value-identical PUT still upserts and still returns 204 but records
nothing.

Attempts are recorded, not only transitions. Identity is assigned before
the authorization check, so a denied PUT exports a 403 row with an empty
diff (no request content reaches it), a validation failure exports a 400
row, and a write failure exports a 500 row, each with an empty diff; an
operator can tell "nothing changed" from "something changed and capture
degraded" by the status code.

The write path stays authoritative. The advisory lock and, on plan-mode,
the transaction exist only to serve change-detection; if any of that
machinery fails (lock, begin, commit, rollback), the handler runs main's
idempotent write path directly and derives the response from it, so a
member-visible failure of audit-only infrastructure can never replace
main's successful response. Accepted consequence: when the lock cannot
be taken, two concurrent identical writes can produce two rows instead
of one. That is audit degradation, which is allowed; changing a member's
response is not. Write failures keep the exact response the endpoint
produced before this wiring (transaction error for the system prompt,
which was always transactional; the raw write error for plan mode, which
was not), and the full transaction error is logged so rollback failures
cannot vanish.

<summary>CODAGT-66 plan entry: S1 (verbatim)</summary>

**S1 `feat: audit chat system instructions changes`** (CODAGT-719; base:
main)

- Struct: `database.ChatSystemPromptSettings{ID uuid.UUID; SystemPrompt
string; IncludeDefaultSystemPrompt bool; PlanModeInstructions string}`
in `coderd/database/types.go` (ticket-sketched shape; one struct, both
endpoints).
- Registration: union entry (diff.go), table.go entry (`id`
ActionIgnore, other three ActionTrack), `AuditActionMap` Write-only;
four request.go cases (`ResourceTarget` "", `ResourceID` from struct,
`ResourceType` new enum value `chat_system_prompt_settings`,
`ResourceRequiresOrgID` false with the "Artificial ID / deployment
singleton" comment convention).
- Migration: `ALTER TYPE resource_type ADD VALUE IF NOT EXISTS
'chat_system_prompt_settings';` comment-only no-op down (000558 shape);
number picked at push per the numbering constraint.
- codersdk: constant + prose `FriendlyString` ("chat system prompt
settings"); `TestAuditDBEnumsCovered` forces both. `coderd/audit.go`
presentation switches: rely on safe defaults (no link, generic
description); no FE changes (filter label falls back to capitalized
value; acceptable per precedent).
- Wiring `putChatSystemPrompt` and `putChatPlanModeInstructions`:
InitRequest with Action Write; artificial `ID: uuid.New()` on `New` only
when a change is detected; no-op suppression by leaving both aReq sides
unset (nil resource IDs skip the log, request.go skip rule); the write
path itself stays byte-identical (upserts still run unconditionally).
- `putChatSystemPrompt` (writes two keys conditionally in one existing
tx): inside that tx, read the pair via `GetChatSystemPromptConfig` for
`Old`, perform the conditional writes exactly as today, then RE-READ the
pair for `New`. The re-read is load-bearing:
`include_default_system_prompt` is computed from the toggle row AND the
prompt, so a prompt-only write can flip the effective value without the
request carrying the pointer. `PlanModeInstructions` stays zero on both
sides.
- `putChatPlanModeInstructions` (no tx exists today): wrap its
read-upsert in `InTx` (behavior-preserving: same single write);
`Old`/`New` populate only `PlanModeInstructions`; the two system-prompt
fields stay zero on both sides; no cross-key reads.
- Change detection compares the populated payload fields only (never the
artificial ID).
- Tests: handler-level coderdtest with `audit.NewMock()` asserting Write
entry on change and NO entry on a value-identical PUT, for both
endpoints (this also exercises `ResourceRequiresOrgID` end to end); the
fallback-flip case (no explicit include-default row, nonempty prompt set
to empty, effective boolean flips: entry emitted with the boolean diff);
diff assertions (old->new prompt text tracked, not secret) in
`enterprise/audit/diff_internal_test.go`; `TestAuditableResources`
passes by construction.
- Bookkeeping at PR open: correct CODAGT-719's no-op premise ("matches
the existing 204-on-unchanged behavior" does not exist on main;
suppression is new, write path unchanged).
- Review focus: Old capture and the New re-read inside the tx (three of
four existing singletons never set Old; do not copy them; and the

Note: the plan excerpt above predates operator decision D5 (2026-07-30),
which this PR implements: the resource type is
`chat_instruction_settings` (not `chat_system_prompt_settings`), each
setting carries a stable ID and a display-name target (not a per-write
artificial ID and an empty target), no-op suppression runs through
`InitRequestWithCancel` (not the nil-ID skip), and attempts (denied,
failed, capture-degraded) record rows with real statuses and empty
diffs. Ticket bookkeeping for CODAGT-719 was corrected on Linear at
kickoff: the ticket's "matches the existing 204-on-unchanged behavior"
premise does not exist on main; suppression is new, and the write path
is unchanged.

Michael Suchacz affeeaf9c8 feat: extend agent chat MCP tools for remote UAT evidence loops (#28233)
Extends the Agent-chat MCP tools so an unattended UAT evidence loop can
fetch artifacts, monitor long runs, and find prior runs without burning
model context.

## Backend

- New `chat_files_token` crypto key feature (migration 000571) with
rotator support and a dedicated signing keycache on coderd.
- `POST /api/experimental/chats/files/{file}/download-url`
(authenticated) mints a short-lived (5 min) signed URL and returns it
with `sha256`, `size_bytes`, `name`, `mime_type`, and `expires_at`.
- `GET /api/experimental/chats/files/{file}/download?token=` (no session
token) redeems the signed URL: verifies the JWS, requires the token's
`file_id` to match the path, and re-checks the minting user's RBAC
access live at redemption. Clients can `curl -o` artifacts with zero
credentials in the URL consumer.
- `ChatFileMetadata` gains `size_bytes` (via `octet_length`, no bytes
fetched).

## MCP tools (`codersdk/toolsdk`)

- `coder_download_chat_file`: by `file_id` or `chat_id`+`file_name`;
returns the signed URL plus checksum and size instead of base64.
- `coder_await_chat`: blocks (bounded `wait_secs`, 1-120) until a chat
leaves `running`/`interrupting`, using the existing watch stream with
subscribe-before-read.
- `coder_list_chats`: label, query, and limit filtering; chat
projections now include labels.
- `coder_get_chat_messages`: `after_id` forward cursor with
`next_after_id` (exact incremental reads), plus per-message `files`
metadata so artifact-bearing messages are identifiable.
- `coder_get_chat`: file listings now include `size_bytes` and
`created_at`.
- `coder_list_templates`: exposes `agents_allowed` for pre-flight
checks.

## Testing

- coderd: mint/redeem happy path with an unauthenticated client,
expired/tampered/file-mismatched tokens, auth still required on the
plain file endpoint, non-owner mint rejection.
- toolsdk: harness + integration coverage for all new/changed tools,
including signed-URL redemption with checksum verification,
forward-cursor exactness, await transition/timeout paths, and label
filtering.
- Remote dogfood UAT (dev.coder.com Coder Agent) passed all six
acceptance scenarios end to end over both MCP transports.

Note: `go test ./codersdk/toolsdk/` has a pre-existing goleak flake on
main (leaked `agentssh` non-PTY session goroutines from SSH exec tests;
reproduced 3/3 on clean `b4971bc49f1`). It is unrelated to this diff.

Michael Suchacz 7724ee281a feat: defer MCP tool schemas behind a find_tools search (#28225)
## Summary

When the `mcp-tool-search` experiment is enabled, chatd stops inlining
connected MCP tool schemas into every generation. It instead exposes a
built-in `find_tools` tool whose description carries a compact catalog
of the deferred tools, and only ships full JSON schemas for tools the
model has activated by searching or by calling them directly.

Closes [CODAGT-760](https://linear.app/coder/issue/CODAGT-760).

## Problem

Tool-heavy agent configurations (GitHub, Linear, Notion, and dev-tooling
MCP servers) inline over 100k tokens of tool schema definitions into
every generation. Initial uncached requests reached ~216k tokens with
time-to-first-token close to nine minutes, while the model typically
invokes only a handful of tools per turn.

## How it works

- `decideMCPToolSearch` defers external and workspace `.mcp.json` MCP
tools whenever the experiment is enabled. Native, dynamic, provider,
skill, and transport tools are never deferred.
- `find_tools` embeds a server-grouped catalog in its tool description
(degrading to names-only, then counts-only, then a constant-size summary
past a context-scaled size cap) and scores keyword matches across tool
names, descriptions, parameter schemas, and server metadata. Queries can
scope to one server with a `server:` prefix, and exact `names` arguments
always activate.
- Activation state is ephemeral: it is re-derived each generation from
surviving chat history (`find_tools` results and direct calls to
deferred tools), so activations naturally lapse when compaction
summarizes them away. Aggregate activated schema weight is capped at 10%
of the context window, shedding the least recently activated schemas
first; `find_tools` shares that budget across parallel calls in one
step. No new persistence.
- Deferred tools stay registered for execution, so the model can call a
cataloged tool directly without searching first; the schema is activated
for subsequent steps.
- Fail-open: the experiment being disabled, an empty candidate set, or
an MCP tool named `find_tools` all disable deferral, leaving today's
behavior byte-identical on the wire.
- Prometheus counters/histograms track `find_tools` calls, matches,
activations, and deferred token weight.
- The conversation timeline renders `find_tools` calls with a collapsed
search summary and expandable match list, falling back to the generic
renderer on malformed payloads.

## Validation

- Unit tests for the catalog, matcher, experiment-gated decision, and
activation derivation; end-to-end chatd generation tests covering
search-then-call, direct-call activation, experiment-off wire parity,
compaction lapse, and subagent tool gating.
- Storybook interaction tests for the timeline rendering and
malformed-payload fallback.
- Remote dogfood UAT on dev.coder.com passed: deferral with a real MCP
server and Anthropic model, direct calls without prior search,
activation persistence across turns, experiment-off parity, and clean
UI/console.

Michael Suchacz 119f2b1dd9 feat: limit concurrent chat agents with pooled admission (#27902)
Limits concurrent chat generation on capped deployments to 5 root chats
and 10 delegated subagent chats. The pools are deployment-wide and
independent, so delegated work can continue while root capacity is full.

The default caps live in AGPL code. Enterprise contributes only a
licensing unlock, so unlicensed deployments stay capped and cannot fail
open. Licensed deployments are uncapped while Agent Hours usage stays
below an explicit hard limit. Deployments without a hard limit remain
uncapped, and reaching the Agent Hours allocation only triggers
warnings.

Admission happens before a worker takes chat ownership. Capped
deployments serialize admission across replicas with a
transaction-scoped advisory lock and derive active and queued state from
current ownership plus fresh runner heartbeats, rather than persisted
queue markers or per-replica state. The acquisition query returns a
bounded, pool-interleaved candidate set instead of ranking the whole
backlog; a migration replaces the acquisition index with a pool-aware
one. Refused chats stay running but unowned, and interrupt requests
bypass admission so users can stop queued or over-cap chats.

The single-chat API derives `queued_for_capacity` from live pool state;
list endpoints do not report it. The UI polls that value every 5 seconds
while a chat is running and shows a callout when the chat is waiting for
capacity.

Updates the administrator documentation and deployment-wide Prometheus
gauges for active and queued agents. Replica-level values must be
aggregated with `max`, not `sum`.

Jaayden Halko fa8ffe4eda feat: report agent runtime hours usage in entitlements (#27985)
Populate `FeatureAgentRuntimeHours.Actual` on every entitlements refresh
for licenses that grant the feature. A new
`GetTotalUsageHBAgentRuntimeV1` query sums `runtime_ms` over the
license's usage period, reading `usage_events` directly:
`hb_agent_runtime_v1` is exactly one row per hourly bucket
deployment-wide with `created_at` at the bucket start, enforced by the
unique partial index introduced in #27983.

The measurement reuses the shared `measureUsage` policy from #27984
through a new `AgentRuntimeMsFn` closure (usage publisher subject):
failures publish the stable
`LicenseAgentRuntimeUsageUnavailableErrorText` and log the cause. Usage
is floored to whole hours, matching the unit of the
`agent_runtime_hours_*` claims, and at most one warning is emitted per
refresh: reaching the allocation supersedes the advisory soft limit. The
dashboard renders the soft-limit advisory muted without a sales link and
treats the runtime usage-unavailable text as a diagnostic.

**Precise usage.** `Feature.ActualMs` (JSON `actual_ms`), set only for
`agent_runtime_hours`, carries the exact stored milliseconds backing the
floored `Actual` so clients can render fractional hours (e.g. `10.3`).
It has the same freshness as `Actual`; the whole-hour warning thresholds
are unchanged.

**Unlimited licenses.** A license minted with the unlimited (`-1`)
allocation decodes to an enabled feature with a nil `Limit` (#27984), so
the warning write-back now guards the allocation dereference: no
thresholds can exist for an unlimited license, so no runtime hours
warning is ever emitted, while `Actual` is still measured and published.
`Feature.Compare` is unchanged; for usage-period features the
issued-at/end dates decide first, so a metered feature outranks an
unlimited one only on an exact timestamp tie, an edge pinned by a
`TestFeatureComparison` case and documented on
`decodeAgentRuntimeHours`.

**Grandfathered premium licenses.** Premium licenses without
`agent_runtime_hours_*` claims are now granted the feature disabled with
a zero limit over the license term, identical to an explicit
`allocation: 0`: usage is measured and published for every Premium
deployment, and chatd's pooled admission (#27902) caps concurrent
agentic chats until a license with a positive allocation is added. The
default carries a fixed early `UsagePeriod.IssuedAt` (2026-08-01, the
same mechanism as the managed-agents default) so any license actually
carrying the claims outranks it in the `AddFeature` merge regardless of
the licenses' relative issue dates; the constant must stay earlier than
the earliest legitimately issued claim-bearing license. Zero allocations
(explicit or grandfathered) emit no deployment-wide warning banner:
those deployments are steered by the in-page upgrade CTA and the
concurrency cap. Enterprise licenses are unchanged.

Jaayden Halko d15800b494 feat: tolerate unusable runtime hours claims and decode -1 allocation as unlimited (#27984)
Two coupled changes to the license/entitlements layer, preparing for
runtime-hours usage reporting.

**Tolerate unusable runtime hour claims.** Unusable
`agent_runtime_hours_*` claim combinations no longer reject the whole
license: rejecting a signed license over a cosmetic threshold claim
would drop the deployment to unlicensed. `decodeAgentRuntimeHours` drops
the unusable claims, surfaces the stable
`LicenseAgentRuntimeHoursClaimsIgnoredWarningText` (deduplicated across
licenses), and logs the affected license and claims through the new
`FeatureArguments.Logger`; `validateAgentRuntimeHours` and its
license-invalidating errors are removed. The dashboard recognizes the
stable diagnostic text and renders it muted, with a "License notices"
heading instead of the exceedance heading and without a sales link.

**Unlimited allocation.** An `agent_runtime_hours_allocation` claim of
exactly `-1` (`AgentRuntimeHoursUnlimitedAllocation`, mirrored in
coder/license) is reserved to mean unlimited: it decodes to an enabled
feature with no `limit` in `/api/v2/entitlements`, the shape the UI
already renders as "Unlimited". Threshold claims alongside it have
nothing to threshold against, so they are dropped with the
claims-ignored warning, and any other negative allocation remains
unusable. The issuer-side counterpart (refusing to mint `-1` together
with threshold claims) is coder/license#49.

The managed agent measurement path is intentionally untouched: managed
agents are deprecated and slated for removal, so the shared
usage-measurement failure policy (`measureUsage`) now lands in #27985
next to its runtime-hours consumer instead of converting a doomed call
site here.

Michael Suchacz 8d4d0b35dd feat: add Coder Agents chat tools to the MCP toolsdk (#28025)
Exposes the experimental Coder Agents chats API through the MCP tool
registry, so MCP clients (the hosted `/api/experimental/mcp/http` server
and `coder exp mcp server`) can start and drive server-side coding
agents.

New tools in `codersdk/toolsdk`, all thin wrappers over existing
`codersdk.ExperimentalClient` methods:

| Tool | Wraps |
|---|---|
| `coder_create_chat` | `CreateChat` (prompt, optional org, model
config, labels) |
| `coder_get_chat` | `GetChat` (status, last error, last turn summary,
workspace, files) |
| `coder_get_chat_messages` | `GetChatMessages` (user-facing parts,
chronological, cursor pagination, queued prompts) |
| `coder_send_chat_message` | `CreateChatMessage` (queue or interrupt
busy behavior) |
| `coder_interrupt_chat` | `InterruptChat` |
| `coder_archive_chat` | `UpdateChat` with `archived: true` |
| `coder_list_chat_model_configs` | `ListChatModelConfigs` (enabled
configs with default flag) |

Both MCP servers register tools from `toolsdk.All`, so no additional
wiring is needed. Responses are trimmed to what an MCP caller needs (IDs
as strings, user-facing transcripts) rather than full SDK payloads. No
new endpoints and no database changes.

Also adds MCP
[prompts](https://modelcontextprotocol.io/specification/2026-07-28/server/prompts)
for the chat workflows, defined once in `codersdk/toolsdk` and
registered by both servers:

| Prompt | Purpose |
|---|---|
| `coder_agents_delegate` | delegate a task to a Coder Agents chat and
monitor it to completion |
| `coder_agents_check` | check the status and recent activity of an
existing chat |

Each prompt declares the tools its workflow needs; the stdio server
skips prompts whose tools are excluded by `--allowed-tools`.

Tests run the tools against a chat-enabled coderdtest instance (fake
OpenAI-compatible provider plus in-process AI bridge), covering the full
lifecycle, an interrupt against a blocked turn, pagination cursors,
permission-dependent model config filtering, and argument validation.
Prompt coverage spans SDK rendering, the hosted
`prompts/list`/`prompts/get` round trip, and the stdio server including
allowlist gating.

Susana Ferreira 2d9b6eda8f feat: add experimental CLI to price unpriced AI models (#27926)
## Description

AI Gateway computes the cost of an interception from `ai_model_prices`,
which is seeded on every server start from a price book embedded in the
binary. A model the price book does not cover records a NULL cost, so
its spend is invisible to cost reporting and is not enforced against
budgets. The only fix was to wait for a Coder release that added the
model.

This adds an experimental CLI, backed by an experimental HTTP endpoint,
for pricing those models. Models the price book already covers are
rejected, because the seeder re-applies the book on every start and
would overwrite an operator price. Support for custom pricing will be
handled in
https://linear.app/codercom/issue/AIGOV-589/extend-experimental-cli-command-to-set-custom-ai-model-prices.

## Commands

```
coder exp ai-model-prices list [--provider] [--model]
coder exp ai-model-prices update [file|-] [--provider] [--model] [--input-price] [--output-price] [--cache-read-price] [--cache-write-price] [--yes]
```

## Changes

- Add `GET` and `POST /api/experimental/ai/model-prices`, gated behind
the AI Bridge entitlement and the existing `ai_model_price` RBAC
resource.
- Add a `GetAIModelPrices` query with optional `provider` and `model`
filters applied in SQL.
- Validate the whole request before writing anything, so one bad entry
cannot leave the table half updated, and report every problem at once.
- Reject prices for models the embedded price book already covers,
through a new `prices.IsDefaultPriced`.
- Add the `coder exp ai-model-prices` command with `list` and `update`.
`update` accepts a JSON document or the single-model flags and prints a
plan, asking to confirm unless the document is piped in or `--yes` is
passed.
- Consolidate the supported provider list into
`coderd/aibridge/prices/providers` so the price generator and the server
share one definition.
- Add `codersdk` types and client methods for both endpoints, and bound
the request body at 1 MiB.
- Document the command in the AI Gateway cost controls page.

Bobby Ho 209d1ca498 fix: reject PKCE code_verifier below RFC 7636 length floor (#28003)
The token endpoint accepted any non-empty `code_verifier`, so a
one-character verifier was enough to authenticate. RFC 7636 §4.1
requires 43 to 128 characters from the unreserved set.

That fix plus the related gaps review surfaced in the same path:

- Enforce the length and charset floor on the verifier before the S256
comparison runs.
- Validate the challenge at the authorize endpoint too. It was only
checked for non-emptiness, so a malformed challenge was stored and then
failed late at token exchange, blaming the wrong parameter.
- A malformed verifier now returns `invalid_request` (RFC 6749 §5.2); a
well-formed but wrong one still returns `invalid_grant` (RFC 7636 §4.6).
Both looked identical before, so a client had no way to tell a syntax
error from a hash mismatch and would retry the same bad verifier
forever.
- Revoke the authorization code when a PKCE check fails. Without that, a
leaked code could be replayed with unlimited verifier guesses for its
remaining lifetime, and RFC 6749 §10.5 requires codes to be single use.
- Fix verifier generation in `scripts/oauth2/*.sh` and the docs example.
They deleted reserved base64 characters instead of translating them to
the URL-safe alphabet, so most runs produced verifiers under the new
floor.

Also carries #28041, which merged into this branch: public clients may
register bare custom schemes such as `vscode://` again, with `mailto`,
`tel`, and `sms` rejected.

Split out of #27873 (public OAuth2 client support). PKCE is already
mandatory for every client, so this stands on its own.

<details>
<summary>Manual verification</summary>

Ran against a local dev server on this branch, using a session token and
a throwaway app from `scripts/oauth2/setup-test-app.sh`.

1. Happy path unchanged: HTTP 200, verifier length 43.
2. `code_verifier=short`, and a 43-character verifier ending in `!`:
both HTTP 400 `invalid_request`, so charset is enforced and not just
length.
3. `code_challenge=tooshort` at authorize: HTTP 400 `invalid_request`,
no code issued. An empty challenge still hits the older "required and
cannot be empty" message.
4. Well-formed but wrong verifier: HTTP 400 `invalid_grant`, distinct
from the cases above.
5. Retrying that same code with the correct verifier: HTTP 400, code
already revoked by the failed check.
6. `generate-pkce.sh` produces a 43-character verifier (20 out of 20
runs); the docs example produces 128.
7. `scripts/oauth2/test-mcp-oauth2.sh` passes end to end. The two
bearer-token failures in its output are a pre-existing script bug
(`09c50559f3`, July 2025) that reuses a resource-scoped token against
the real API, not a regression here.

Michael Suchacz 1458d27d78 fix: allow manual chat compaction from the error state (#28022)
A chat that fails generation with a context overflow (for example `Input
length 262625 exceeds the maximum allowed input length of 262112
tokens`) is stuck in a catch-22: `POST /chats/{id}/compact` returns 409
because the `RequestCompaction` transition is only allowed from the
waiting state, and the only other way out of the error state is sending
or editing a message, which re-runs generation with the same oversized
prompt and fails again. Compaction is exactly the recovery a
context-overflowed chat needs, and it is unreachable exactly when it is
needed.

Three semantic changes:

- Allow `RequestCompaction` from the error states: `E0 -> R0` and `E1 ->
R1` (queued messages are preserved and processed after the compaction
turn).
- Clear `last_error` in `Tx.RequestCompaction`, matching the
architecture rule that transitions leaving `E0`/`E1` clear the stored
error. Without this a successful compaction would land in waiting with a
stale persisted error.
- Grant the compaction turn a fresh history epoch: a
`grant_history_epoch` flag on `UpdateChatExecutionState` sets
`history_version = snapshot_version`, resets `generation_attempt`, and
clears `retry_state` in the same atomic update that clears `last_error`
(mirroring the `chat_messages` trigger postcondition). The transition
inserts no history, so without this the turn inherits the failed turn's
spent retry budget, and resetting the counter alone could collide with
message part episode keys still retained on the erroring replica.

No frontend change is required: the chat input is already enabled in the
error state and `/compact` submission already handles both the success
and 409 paths. Also updates ARCHITECTURE.md (transition matrix,
endpoint, and manual compaction sections), the endpoint's swagger
description, and SDK comments.

J. Scott Miller 866e676320 feat: invalidate provisioner daemon sessions on key deletion (#26532)
## Summary

Closes PLAT-305.

When a provisioner key is deleted, the associated daemon kept operating
on its existing WebSocket connection, because authentication was only
checked at connection establishment and deletion was a bare `DELETE`
with no session invalidation.

This adds four layers of defense so a deleted key promptly stops doing
work:

1. **Publish on delete.** `deleteProvisionerKey` publishes to a new
per-key pubsub channel (`coderd/pubsub.ProvisionerKeyDeletedChannel`)
after a successful delete. Publish errors are logged but still return
`204`, since layer 3 is the durable backstop.
2. **Subscribe and tear down.** The daemon serve handler subscribes to
its key's channel and terminates the DRPC session on a deletion event.
Termination is deferred while a job claimed by the session is active:
the daemon may finish and report the in-flight job
(`UpdateJob`/`CompleteJob` have no key check), and the last active job's
completion performs the cancellation. Because Postgres `LISTEN`/`NOTIFY`
does not buffer for non-listeners, the handler also performs a
synchronous key-existence re-check immediately after subscribing to
close the race between auth and subscription. The subscription uses
`SubscribeWithErr` so that an `ErrDroppedMessages` signal (emitted when
the pubsub listener reconnects) triggers the same key re-check, closing
the listener-outage window in which a deletion notification could be
missed.
3. **Backstop on acquire.** `AcquireJob` and `AcquireJobWithCancel`
verify the key still exists before waiting for a job, and the `Acquirer`
claims jobs in a transaction that first locks the worker's deletable key
(`LockProvisionerKeyByIDForShare`, a `FOR KEY SHARE` row lock held until
commit) before running the `AcquireProvisionerJob` claim, so a claim
cannot commit after the key's deletion. This guards against a missed
pubsub message. A missing key row surfaces as its own result rather than
overloading the claim query's no-rows response: the acquire terminates
with `ErrProvisionerKeyDeleted` (terminating the session, with the same
active-job deferral) and hands the consumed wakeup to another waiting
daemon in the same domain, rather than silently re-parking and starving
peers of job postings.
4. **Heartbeat watchdog.** The per-session heartbeat loop (1m interval)
also re-checks the key, so even a session whose deletion notification
was silently lost terminates within one heartbeat interval instead of
living until the connection breaks (same active-job deferral as layer
2). Reserved keys skip the check.

A job that is claimed but never delivered (the session or connection
dies between the database claim and the stream send) is marked failed
immediately on a fresh context, instead of staying assigned to the
worker until the job reaper.

Reserved keys (built-in, user-auth, PSK) are exempt throughout, since
they are not deletable rows. The acquire-time lookup runs as
`dbauthz.AsSystemReadProvisionerDaemons`, because the provisionerd role
cannot read provisioner keys and a provisioner key's RBAC object is a
provisioner daemon.

A single key can back many daemons (and span HA replicas), so the
per-key channel fans out to invalidate all of them at once. Per-key
channels keep the `LISTEN` count proportional to distinct keys rather
than waking every daemon on unrelated deletions.

### Known limitations

- **`UpdateJob`/`CompleteJob` intentionally have no key check.** By the
time those RPCs arrive the work has already run; rejecting completion
would strand a build in "running" (until the job reaper fails it) with
real infrastructure left unreconciled. Session termination is deferred
while a job is active so the completion can be reported; the daemon may
not receive the final RPC response when the deferred termination fires,
but the job's outcome is already persisted.
- **After termination, the daemon process redials and receives 401s
until restarted.** The dial-time exit logic only triggers on 403, and
the auth middleware returns 401 for an invalid key; this dial behavior
predates this PR and is tracked as a follow-up in
[PLAT-452](https://linear.app/codercom/issue/PLAT-452) (return 403 for
invalid provisioner keys).

## Tests

- `coderd/provisionerdserver`: `TestAcquireJob_ProvisionerKeyDeleted`
(both RPC variants), `TestAcquireJob_ReservedProvisionerKey`,
`TestHeartbeat_ProvisionerKeyDeleted` (heartbeat watchdog cancels the
session after key deletion), `TestAcquirer_ProvisionerKeyDeleted` (a
dead-key acquiree exits terminally and its clearance is promoted to a
peer in the same domain), and `TestTerminateSession_Deferral`
(termination is immediate when idle and deferred until the last active
job finishes).
- `coderd/database`: `TestAcquireProvisionerJob/ProvisionerKeyLock`
covers the lock query against real Postgres: it returns the key ID while
the row exists and no rows once it is deleted. The lock-then-claim
composition is pinned by `TestAcquirer_ProvisionerKeyDeleted`.
- `enterprise/coderd`:
`TestProvisionerDaemonServe/KeyDeletionClosesSession` asserts an active
session closes after its key is deleted.
`KeyDeletedDuringSetupClosesSession` covers the post-subscribe re-check
when a key is deleted between auth and subscription, and
`DroppedMessageClosesSession` covers the `ErrDroppedMessages` re-check
when a deletion is missed during a listener outage.

## Validation

- `make` pre-commit (gen/fmt/lint/build) passed via git hooks.
- Targeted tests pass; existing acquire tests pass with no regression.
- Manual: brought up a dev deployment (coder-in-coder) with a Premium
license, created a deletable provisioner key, and started an external
daemon with `coder provisionerd start`. Confirmed it authenticated via
the key and connected, appearing as `idle` in both `coder provisioner
list` (with the key name) and the organization Provisioners UI.
- Manual, idle teardown: deleted the key while the daemon was idle. The
server logged `provisioner key deleted, terminating session`, the
daemon's session closed immediately, and it dropped from `coder
provisioner list` (then entered the known 401 redial loop, PLAT-452).
- Manual, deferred termination: ran a workspace build (tagged template,
`sleep 45` in `local-exec`) pinned to the external daemon and deleted
the key mid-build. The server logged `deferring session cancellation
until active jobs finish`; the heartbeat watchdog re-checked mid-build
and re-deferred rather than force-killing. The build ran to completion
(`Apply complete`, workspace `Started`) and only then did `canceling
session after job completion` fire. The documented caveat reproduced:
the daemon lost the final `CompleteJob` ack, and the build outcome was
still persisted correctly.

<details>
<summary>Implementation plan and design decisions</summary>

### Design

- **Per-key vs global channel:** chose per-key
(`provisioner_key_deleted:<keyID>`) so daemons do not wake on unrelated
deletions. The cost is one `LISTEN` per distinct key per replica on the
shared listener connection, which is negligible against Coder's existing
channels.
- **Missing-key behavior on acquire:** returns an error that tears down
the acquire rather than silently returning an empty job.
- **Subscribe-startup race:** ordering is `authorize ->
UpsertProvisionerDaemon -> Subscribe -> GetProvisionerKeyByID`. The
post-subscribe re-check handles a deletion that committed before the
`LISTEN` registered (Postgres does not buffer notifications for
non-listeners; the in-process buffer only smooths bursts and drops on
overflow).
- **`NewServer` change:** `KeyID` was added to
`provisionerdserver.Options` to avoid a positional signature change
across call sites. The in-memory (built-in) daemon leaves it unset and
is therefore exempt.

### Files

- `coderd/pubsub/provisionerkeydeleted.go` (new) — channel helper.
- `enterprise/coderd/provisionerkeys.go` — publish on delete.
- `enterprise/coderd/provisionerdaemons.go` — subscribe, re-check,
cancel session; pass `KeyID`.
- `coderd/provisionerdserver/provisionerdserver.go` — `KeyID` option and
acquire-time existence check.

Jaayden Halko 5bdabc95c8 fix(codersdk/licenses.go): read trial claim instead of misspelled trail (#28014)
## What this fixes

`codersdk.License.Trial()` looked up the JWT claim `"trail"` (a typo)
instead of `"trial"`, the actual claim name set by license issuance
(`enterprise/coderd/license/license.go`). Since no license contains a
`"trail"` claim, the method always returned `false`.

The only consumer is `coder licenses list` (via
`cli/cliutil/license.go`), so the CLI never reported a license as a
trial even when it was one. The web UI is unaffected because it reads
`claims.trial` directly.

## Changes

- Read the `"trial"` claim in `License.Trial()`.

## Testing

- `go build` / `go vet` on `codersdk` and `cli/cliutil`.
- `go test -run 'TestLicensesListFake|TestLicensesListReal'
./enterprise/cli` passes.

Steven Masley 9a57dfa642 feat: include agent metadata in workspace list responses (#27934)
Closes #27933. Related: #27897 (single-agent GET).

Agent metadata is only readable via a per-agent watch stream, so reading
it across N workspaces costs N+1 requests. This adds a batch read to the
list endpoint:

```text
GET /api/v2/workspaces?q=param:"pool=demo" include_agent_metadata:task_status
```

- New `include_agent_metadata` search key, repeatable and key-scoped. It
expands the response, it does not filter workspaces.
- `GetWorkspaces` aggregates the requested keys as JSON behind a `CASE`:
without opt-in the response is unchanged and the subquery never runs.
Runs only for the returned page, inside the same authorized query.
- Agents in the response gain `metadata`
(`[]codersdk.WorkspaceAgentMetadata`, `omitempty`), mapped by the
`workspace_agent_id` each element carries. The collection script is
omitted; it can be long.
- `codersdk.WorkspaceFilter` gains `IncludeAgentMetadata []string`.
- No wildcard, no schema change, no migration.

dylanhuff-at-coder 9b27d12929 chore: forbid direct response body JSON decode in codersdk (#27859)
Add a ruleguard rule forbidding direct
`json.NewDecoder(res.Body).Decode(...)` on `*http.Response` in codersdk
packages, so new typed endpoints use `codersdk.ReadBodyAsJSON` and keep
returning structured errors for non-JSON bodies. The rule matches both
the chained call form and decoders assigned to a variable first.

Intentional raw-body paths carry documented `//nolint:gocritic`
exceptions: the 16 agent-direct HTTP decodes in
`workspacesdk/agentconn.go` route through a single `decodeAgentJSON`
helper (agent-direct over tailnet, so `ReadBodyAsJSON`'s reverse
proxy/SSO error guidance does not apply), and the Azure IMDS
attested-document decode in `agentsdk/azure.go` keeps an inline
exception.

The two `UseNumber` decoders in `licenses.go` are migrated to a new
`codersdk.ReadBodyAsJSONUseNumber`, so `coder licenses add/list` also
return structured errors for non-JSON bodies instead of `invalid
character '<' looking for beginning of value`.

Note for local verification: golangci-lint caches results, so run
`golangci-lint cache clean` after modifying `scripts/rules.go` or the
rule may silently not fire.

Final PR of the stack on #27804, #27857, and #27858. Refs #27044.


Stack plan

Inventory (full-tree audit): 280 migratable call sites across 47 files;
17 excluded (16 agent-direct HTTP sites in `workspacesdk/agentconn.go`,
1 Azure IMDS decode in `agentsdk/azure.go`).

1. **#27857** `refactor(codersdk): use ReadBodyAsJSON in typed
endpoints`: mechanical migration of all sites except `chats.go` (224
sites, 46 files).
2. **#27858** `refactor(codersdk): use shared error helpers in chat
endpoints`: migrate the 56 `chats.go` sites and consolidate the
duplicated `readRawBodyAsError`/`newResponseError` helpers onto the
shared `client.go` error path, with regression tests for the 409
usage-limit flow.
3. **#27859** `chore: forbid direct response body JSON decode in

raw-body paths, plus `ReadBodyAsJSONUseNumber` for the `licenses.go`
decoders.

Ethan d2f9280138 chore: remove legacy chat template allowlist (#27515)
Relates to CODAGT-713

Depends on #27514

Removes the legacy deployment-wide allowlist now that the API and frontend use per-template `agents_allowed`: the experimental `/template-allowlist` routes, SDK methods and generated types, site config queries, frontend bindings, and the now-unused `xjson` utility.

Migration `000563` deletes the obsolete `agents_template_allowlist` value. It's irreversible for deployments that configured an allowlist, which I think is fine, since `000562` already drops `agents_allowed` on the way down, and this release ships `000548` and `000555` with the same property.

Two side effects of the model change worth writing down, both from #27514 rather than here. The value used to need `ActionRead` on `ResourceDeploymentConfig` to read and deployment config update to write. `AgentsAllowed` is now a plain field on the template response, readable by anyone who can read the template, and it's set with a template update, so org admins manage it themselves. That's the delegation we wanted, and it's tracked in the audit log.

The rest of the stack adds `--agents-allowed` to the CLI and updates the platform controls docs.

Ethan 0ac23e3ee1 feat: add per-template Coder Agents access control (#27285)
Relates to CODAGT-713

Depends on #27284

This makes the per-template `agents_allowed` field authoritative in the API and chatd. It adds optional create and metadata update fields with the intended default and omission semantics, supports `agents-allowed:` template search, includes the value in telemetry, and makes `list_templates`, `read_template`, and `create_workspace` read the template row directly. Existing-workspace retries remain idempotent, and blocked same-organisation templates return an actionable message.

The experimental `/template-allowlist` routes remain temporarily because the shipped AI Settings page still calls them, but they no longer control chatd enforcement. #27514 moves that page to per-template metadata, #27515 removes the legacy storage, routes, SDK types, and utility, #27517 adds the CLI flags, and #27518 updates the platform controls documentation for the per-template model, directly addressing CRF-5 and CRF-6. The stack is intended to merge as a unit.

Michael Suchacz 4b9880afa6 feat: add --chat-hook-allow-insecure to allow plain HTTP chat hook URLs (#27896)
Adds a hidden `--chat-hook-allow-insecure` /
`CODER_CHAT_HOOK_ALLOW_INSECURE` deployment option (default `false`)
that allows the chat lifecycle hook URL to use plain HTTP for any host.

The HTTPS requirement is enforced at two points, and the flag relaxes
both: `DeploymentValues.Validate()` rejects `http` hook URLs at startup,
and the hook dispatcher's `validateHookURL` allows `http` only for
loopback hosts. With the flag set, any-host `http` is accepted; the
host, fragment/userinfo, secret, and timeout checks are unchanged, and
non-http(s) schemes still fail. This removes the need for an HTTPS
reverse proxy when testing a hook consumer on a trusted network.

Following security review feedback, the flag description and docs state
that plain HTTP lets an on-path attacker forge hook responses (which
control agent execution), and `coder server` logs a startup warning
(with a redacted hook URL) when hooks run over plain HTTP.

Docs, generated API types, and the server config golden are updated
accordingly.

Nick Vigilante 9dcb75cd56 chore: add docs inline-HTML linter and backtick generated placeholders (#27399)
## What

Adds CI enforcement that fails when docs Markdown contains invalid
inline HTML
the docs site silently drops or mangles, and fixes the remaining
generated-doc
placeholders at their source.

This is the tooling half of the docs-HTML audit. The hand-written fixes
it
guards landed in #27298 (kept small and separate so it reviewed fast);
this PR
carries everything that touches code, CI, or generated output.

## Changes

**Linter (`scripts/docshtmlcheck`), wired into `make lint` via
`lint/docs-html`.**
Markdown-aware: parses each file with goldmark and inspects only
raw-HTML nodes,
so angle brackets in fenced code blocks, inline code, HTML comments, and
`<https://…>` / `<user@host>` autolinks are ignored. Flags swallowed
placeholders (`<region>`), void-element end tags (`</br>`), unregistered
or
incorrectly capitalized component tags (`<Image>`), and unclosed
container tags (a
`<div class="tabs">` that leaks its wrapper). The one intentional
renderer
component, `<children>`, is allowed but still balance-checked.

**Generator-source placeholder fixes (regenerated via `make gen`).**
- `codersdk/chats.go`: backtick `<server>__` in the
`ChatContextTool.Name` doc
  comment (it becomes the Swagger description, so it was swallowed in
  `reference/api/{chats,schemas}.md`).
- `codersdk/deployment.go`: backtick `<region>` in the AWS Bedrock
region flag
help (swallowed in `reference/cli/server.md`); also updates `coder
server
  --help` output and the golden files.

**Temporary allowlist.** `docs/reference/cli/agent-firewall.md`'s
`<host>` /
`<glob>` come from the external `github.com/coder/boundary` CLI help
(still
`v0.10.0` on `main`), so they are suppressed on that one file. The
suppression
is self-clearing: if an allowlisted tag stops appearing on a scanned
file, the
linter reports `stale-allowlist-entry` and fails until the dead entry is
removed, so a dead entry cannot silently mask a later regression of that
tag on
that page. (An entry whose file is deleted outright is never rescanned,
but a
missing file yields no findings, so nothing hides behind it either.)

## Review feedback addressed

This tool + generator work was reviewed by Coder Agents Review while it
was
bundled into #27298. Addressed here:

- **P1:** tokenize each raw-HTML node as a whole instead of per source
line, so
a tag whose attributes wrap across lines is no longer torn in half. This
fixes
both the missed multi-line unclosed `<div>` (a leaked wrapper that
passed with
exit 0) and the spurious `stray-end-tag` on valid multi-line tags. Each
token
  maps back to its own source line.
- Normalize allowlist lookup/report paths to a canonical repo-relative
form, so
the escape hatch no longer silently misses under absolute / `./` paths.
- Route generated-page findings to the generator source.
- Add `<search>` to the allowed set; reword the unknown-element message
to note
  that a real element can be added to `allowedElements`.
- Self-clearing allowlist guard (above); rename `optionalEndTag(s)` and
`kindUnclosed(Tag)`; adopt `slices`/`maps` idioms; move the lint banner
to the
  Makefile recipe; stop aliasing the input slice in `filterAllowed`.
- New tests: multi-line tokenization (both classes), interleaved
nesting, a
  pinned line number, `collectMarkdown`, and the stale-allowlist guard.

### Round 2 (Coder Agents Review on this PR)

A second `/coder-agents-review` pass on this PR raised 16 findings;
addressed in
`fix(docshtmlcheck): catch self-closing containers and capitalized
tags`:

- **P2:** self-closing container tags (`<div class="tabs"/>`) were
ignored by
the HTML5 parser and leaked their wrapper like the open spelling; the
balance
  check now tracks self-closing tokens too (CRF-1).
- **P2:** a capitalized component tag whose lowercase name is a real
element
(`<Table>`, `<Section>`) slipped through on the `allowedElements`
lookup. The
tokenizer lowercases tag names, so the check now reads the raw token and
  reports any capitalized name as a component reference (CRF-2).
- Narrowed the `:` / `@` autolink skip to a real URI scheme or a dotted
`local@domain`, so `<region:id>` and `<user@host>` stay checked (CRF-3).
- Stale-allowlist findings now report against the linter source with no
line,
and count separately from invalid-HTML issues in the footer (CRF-7,
CRF-11).
- Comment / README / Makefile wording synced to the honest
capitalized-tag
  behavior; added the deleted-file allowlist caveat and a note that
`allowedElements` is hand-maintained against the renderer (CRF-14,
CRF-17,
  CRF-9).
- Internal cleanups (`pop` -> `matchEndTag`, extracted
`unclosedFinding`) and
new tests: self-closing, capitalized open/close, colon/at placeholders,
a
non-first-token line assertion, `isGeneratedDoc`, and the stale message
  (CRF-12, CRF-13, CRF-1/2/3/4/5/16).

Two findings resolved without a code change:

- **CRF-8** (also wire `lint/docs-html` into `lint-light`): declined.
  `lint-light` is the Go-free fast path; `lint/docs-html` needs the Go
toolchain, so it stays in the full `make lint`, which CI runs. Adding it
would
  pull Go into the light path for no coverage gain.
- **CRF-9** (`allowedElements` <-> renderer coupling): documented with a
maintenance note in the `allowedElements` comment and tracked in
DOCS-597 for
  a cross-repo sync/check decision.

Deferred (note, no current trigger): raw-text element interiors
(`<script>` / `<style>`) are not scanned for nested tags. No docs page
relies
on this today; noted for follow-up.

## Merge order

#27298 (the hand-written fixes this PR guards) has merged, and this
branch is
rebased on `main`, so `make lint/docs-html` now reports 0 findings and
the
`lint` check passes. The two PRs are independent (disjoint files, no

Michael Suchacz 6b8f820493 feat: remove native chat cost tracking in favor of AI Gateway cost data (#27330)
## Stack Context

This stack makes AI Gateway data and budgets the source of truth for AI
spend controls.

1. Re-back the per-chat cost endpoint with AI Gateway data (#27328,
merged).
2. Remove native chat usage limits (#27329, merged).
3. **This PR, now based on `main`:** remove native chat cost tracking
and its dedicated admin UI.

## Summary

Removes native per-message price calculation, model pricing fields, cost
persistence, aggregate cost queries, and admin cost API types. It also
deletes the Analytics and Spend pages plus their legacy redirects. The
AI Gateway-backed per-chat cost row and compact budget indicators
remain.

The spend documentation is renamed to `spend-management.md` and updated
for the remaining surfaces, group budget APIs, CSV export, upgrade
handling for native pricing and cost history, and the absence of a
deployment-wide spend dashboard. The per-chat cost API documents that
data follows AI Gateway retention and reports zero after all matching
requests are purged.

No schema is dropped in this release. `chat_messages.total_cost_micros`
remains nullable and unwritten so replicas from the previous release can
continue inserting messages during rolling upgrades. #27600 tracks
removal after the compatibility window.

2. **This PR:** remove native chat usage limits.
3. Remove native chat cost tracking and its dedicated admin UI (#27330).

## Summary

Removes the native usage-limit API, SDK types, SQL, and chat enforcement
for deployment, user, and group chat limits. Compact AI Gateway budget
indicators remain in the Agents sidebar, user menu, and group settings.
Gateway budget rejections and provider quota failures continue to
classify as usage-limit errors, including a 409 response for synchronous
title generation.

Budget-period labels now use the API's UTC boundaries, so users see the
same dates in every browser timezone. The documentation explains the AI
Gateway replacement, its licensing requirements, and the differences
from native limits.

No schema is dropped in this release. The usage-limit table, index, user
and group columns, constraints, audit mappings, and generated scan
fields remain for mixed-version rolling upgrades. #27600 tracks their
removal after the compatibility window.

## Breaking change

Native day, week, and month chat spend limits are removed and are not
migrated. AI Gateway budgets are month-based, group-scoped with per-user
overrides, and require the AI Gateway entitlement. Deployments without
that entitlement no longer have chat spend enforcement.

Michael Suchacz c6cee10e8b feat: add per-model OpenAI Responses API toggle (#27683)
chatd hardcoded `WithUseResponsesAPI()`, so the provider SDK's static
known-model list decided whether an OpenAI model spoke the Responses API
or Chat Completions. A model absent from that list silently fell back to
Chat Completions until the fantasy fork was patched.

This exposes the SDK's `WithResponsesAPIFunc` hook as a per-model
setting, `openai_config.use_responses_api`, stored in the existing
`chat_model_configs.options` JSONB. Unset keeps the known-model list,
`true` forces Responses, `false` forces Chat Completions. There is no
migration.

It sits in a new construction-time `openai_config` section rather than
in `provider_options.openai` because it selects the API when the client
is built, while `provider_options` holds per-request parameters. That
placement is also load-bearing: a config setting only this field would
otherwise materialize an OpenAI request-options struct and turn on
provider-side response storage, since `Store` defaults to true there.

Three places independently decided the transport and would silently
disagree with the client actually built:

| Site | Effect when it disagrees |
| --- | --- |
| `ModelFromConfig` | the transport being overridden |
| `AcceptsFilePartMediaType` | text attachments dropped, since Responses
natively accepts only images and PDFs |
| `UsesResponsesOptions` | the SDK type-asserts the concrete options
struct, so every OpenAI option is discarded |

They share one predicate here, `chatopenai.UsesResponsesAPI`, with the
override threaded to each. The rest of the stack removes that threading
by resolving the transport once and carrying it. Compaction overrides
and the quickgen debug model built clients without `ConfigOptions`, so
they now pass it and pick up both this setting and the existing
Anthropic beta headers.

The toggle also makes transport-conditional option handling
admin-switchable, so two hardening changes ride along.
`ServiceTierFromChat` now maps every tier the codersdk enum advertises
(`auto`, `default`, `flex`, `scale`, `priority`); it previously returned
nil for `default` and `scale`, so flipping a model to Responses silently
dropped a configured `service_tier` that the API accepts (fantasy
forwards the value unchanged). And a new
`TestProviderOptionsTransportParity` pins, per `provider_options.openai`
field, which transport honors it, against a table in ARCHITECTURE.md, so
a field honored on one transport and silently ignored on the other fails
the test unless recorded as intentional.

Review rounds also caught two lifecycle gaps around the new field.
`isZeroChatModelCallConfig` now inspects `OpenAIConfig`, so a stored
options blob whose only setting is this toggle survives into GET/list
responses instead of reading as `model_config: null`;
`TestIsZeroChatModelCallConfigCoversEveryField` sets each config field
in isolation and fails if any field is invisible to the zero check. And
the model editor's update path sends an explicit empty `model_config`
when an edit clears the last field, since an omitted property preserves
the stored options server-side; covered by the
`EditClearingLastOptionSendsEmptyConfig` story.

Azure keeps following the known-model list, because the Azure provider
exposes no equivalent hook. The model editor renders Azure with the
OpenAI option schema, so instead of shipping a visible but inert
control, the option schema generator gains a `providers` struct tag that
it emits as `visible_for_providers`. Gating uses the raw provider type
rather than the alias table, so the control appears only for
openai-typed providers. No hand-written frontend field: the editor
renders it from the generated schema.

Steven Masley 52423eb87b feat: promote MinimumImplicitMember experiment to GA (#27472)
Promotes the `minimum-implicit-member` experiment to GA and removes it.

## What changes

- The `minimum-implicit-member` experiment constant, its
`RoleOptions.MinimumImplicitMember` toggle, and the global
`rbac.MinimumImplicitMember()` accessor are deleted. The minimal-member
behavior is now the only behavior: `organization-member` and
`organization-service-account` carry only the floor (read-self records,
notifications, and similar) and grant **no workspace permissions**.
Workspace access lives exclusively on the
`organization-workspace-access` role.
- The experiment gate on customizing `default_org_member_roles` (`PATCH
/organizations/{org}`) is removed; the built-in-roles-only validation
remains.
- The dashboard's Default Roles section and the implied-roles display on
the members page are no longer experiment-gated.
- Admin docs: new "Default member roles" section in
`docs/admin/users/organizations.md`, cross-linked from
`groups-roles.md`.

## Why this is safe for existing deployments

Migration `000516` (shipped earlier) backfilled
`default_org_member_roles` with `['organization-workspace-access']` on
every organization. Members therefore keep exactly the effective
permissions they had with the experiment off; the workspace elevation
flows through the default role instead of being baked into
`organization-member`.

**Rollback caveat:** rolling back past this release restores the bundled
elevation, silently re-granting workspace access to members of
organizations that cleared their default roles.

## Review

Deep-review R1 findings are addressed in `chore: address deep-review

Michael Suchacz df1c0f9710 feat: show what a chat lifecycle hook changed (#27655)
## Stack Context

Follow-up fixes from live UAT of the merged chat lifecycle hooks stack
(#27430). Two PRs:

1. **This PR**: make hook effects visible and correctly attributed in
the transcript.
2. [`mike/chat-hooks-uat/dispatch-capacity`]: reserve dispatch capacity
so an admission burst can't fail running turns.

## Why?

UAT found three ways the transcript misrepresented what a lifecycle hook
did. All three are user-visible and share the same surface
(`chathooks/effects.go`, `codersdk.ChatMessagePart`, the conversation
timeline), so they're reviewed together.

**A prompt `input_override` silently discarded attachments.**
`ComposeUserPromptContent` replaced the entire submitted part list with
one text part, dropping `file` and `file-reference` parts along with
their `chat_file_links`. The user saw their attachments vanish with no
explanation. The override now replaces submitted *text* parts only and
preserves non-text parts in order. A consumer that wants to block
attachments uses `deny`, which is the documented mechanism for refusing
a submission.

**Every user-visible `system` row was labelled "Lifecycle hook".** The
timeline keyed the notice off `role === "system"`. That was correct only
by accident, because the hook `user_message` was the sole client-visible
system row. The backend now emits the notice as a typed `hook-notice`
part and the timeline renders on that, so a future system row can't be
mislabelled as a policy notice.

**Nothing marked a tool call the hook had rewritten.** A consumer could
replace tool input via `input_override` and the transcript showed the
rewritten input as if the model had produced it. `ChatMessagePart` gains
`hook_rewritten`, set from `preflight.Overrides` on the same path that
already carries `ToolCallCreatedAt`, and the tool row renders a
"Modified by policy" badge.

`ToolCall.PolicyProvider` renders the badge itself, at four wrap sites:
the `Tool` dispatch wrapper, the `ReadFilesTool` aggregate and its
per-file rows, and `ReadFileTimelineBlock` (grouped and single
`read_file` rows bypass `Tool`). Renderer props do not include the flag;
descendants consume it through the provider context.

The badge is emitted by the provider rather than by the shared header
because several renderer branches return early without one, including
the auth-required `execute` card, a completed `ask_user_question`, and
an empty question payload. Those branches would drop the attribution
with no type or runtime error, and the gap is not greppable: every
renderer file contains a header somewhere, only individual branches do
not. Emitting at the provider removes the possibility instead of
enumerating the cases.

A rewritten call is wrapped in a group labelled by its badge, so one
rewritten file inside a merged read is attributed on its own rather than
inheriting the group's badge. `HeaderButton` still appends the policy
wording to an explicit `ariaLabel`, since an explicit `aria-label`
replaces the name computed from descendants.

Provider-executed calls are excluded from attribution. Hooks never see
them, and duplicate tool-call ID rejection deliberately skips them, so a
reused ID would otherwise mark a provider-executed call as
policy-rewritten.

## Testing

Go: `coderd/x/chatd/...`, `coderd/x/agenthooks/...`, `codersdk/...`, and
`coderd -run 'Hook|Chat'`. Frontend: `tsc` plus every `AgentsPage`
story; the only failures are `MCP Tool Completed` and `Scroll To Bottom
Button Works With Inverse Scroll`, both of which fail on trunk.

A registry-wide story asserts every registered renderer shows the badge,
verified against three inverted toggles: removing the badge, hiding it
with `display:none`, and skipping the provider for one renderer (which
names that renderer). Storybook also covers the rewritten subagent
spawn, a completed empty question payload, a non-hook system message,
and a failed `read_file` guarding the accessible name.

Ethan 4dbb3a236c test: fix tailnet connection teardown flake (#27768)
Closes https://github.com/coder/internal/issues/1620
Closes ENG-3043

The callback cleanup added in #20687 stops new node callbacks, but it
can still race with one that's already in flight. That callback may call
`UpdatePeers` after the destination `tailnet.Conn` closes, so the test
fails with `connection closed` even though the redirect behaviour is
correct.

To fix, we'll just ignore `tailnet.ErrConnClosed` in the asynchronous
`stitch` helpers, whilst continuing to assert on every other error.

Sas SwartandClaude Opus 4.8 8886a5749a feat: add network calls list to AI session threads API (#27425)
The AI session threads API returned only a network call *summary*
(total/blocked counts + top domains). This adds the per-call list so the
session detail can render individual Agent Firewall network calls.

`ListAIBridgeSessionNetworkCalls` reuses the same sequence-number
windowing as the existing summary and includes all protocols. The list
is exposed as `network_call_logs` on the threads response and is capped
server-side at 100 rows. The summary (`network_calls.total`/`blocked`)
remains authoritative for whole-session totals: the list length and its
blocked count equal the summary only when a session has at most 100
calls, and are truncated beyond that.

Backend for the AI session network summary. Exposes total/blocked
network calls and top destination domains on the session threads
endpoint (`GET /api/v2/ai-gateway/sessions/{id}`).

Total and blocked reuse the existing Agent Firewall aggregation from the
sessions list query, so the numbers match the sessions table. Top
domains are a new server-side aggregation
(`GetAIBridgeSessionTopDomains`) over boundary logs, using the same
interception-window correlation. There is no network-error state,

Michael Suchacz 95a2c2ba02 feat: back the per-chat cost endpoint with AI Gateway data (#27328)
## Stack Context

This stack removes native chat cost tracking and native chat usage
limits, making the AI Gateway the single source of AI spend data and
budget enforcement.

1. **This PR:** re-back the per-chat cost endpoint with AI Gateway data.
2. Remove native chat usage limits end to end, rewiring the sidebar
indicator to gateway spend.
3. Remove native chat cost tracking end to end, deleting the
Analytics/Spend cost UI.

## What?

`GET /api/experimental/chats/{chat}/cost` summed
`chat_messages.total_cost_micros`, which native chat cost tracking
maintained. It now aggregates AI Gateway interception data instead, and
has no native fallback.

- New `GetAIBridgeChatCost` query, authorized through the root chat so
members can read their own chat's cost without gaining access to raw
interception rows.
- Response fields renamed: `priced_message_count` -> `request_count`,
`unpriced_messages_having_usage_count` -> `unpriced_request_count`.
- The chat summary sidebar keys its cost cache by root chat, and hides
the cost row where the AI Gateway is off or unlicensed. The root cost is
invalidated when a chat leaves an active status and when a generated
title lands, since title generation bills its own gateway request.

`GetChatModelUsageCostByChatID` and the rest of native cost tracking are
untouched here; PR 3 removes them.

## Why?

Native cost tracking duplicates what the AI Gateway already records, and
the two disagree. Repointing the endpoint first means the cost UI keeps
working while the native implementation is deleted later in the stack.

Two behaviour changes follow from gateway semantics and are intentional:

- **Requests, not messages.** The gateway records interceptions, so
counts are requests. Title-generation traffic now counts.
- **Whole-tree totals.** The gateway records the *spawning* chat's ID as
the interception session ID, so a subagent's requests are attributed to
its immediate parent, not always the root. Only a whole chat tree can be
summed, so the query resolves the root and aggregates the tree, and
every chat in a tree reports the same total. Native returned per-subtree
totals.

## Attribution and counting semantics

The aggregate groups token usage per interception before counting, so
the reported numbers are per request even though a request records one
usage row per provider response:

- `RequestCount` counts finished `Coder Agents` interceptions in the
tree, including unpriced ones.
- `UnpricedRequestCount` counts requests with at least one usage row the
gateway could not price. It is a subset of `RequestCount`.
- `TotalCostMicros` omits only unpriced usage, so a partially priced
request still contributes its priced portion. The sidebar therefore says
`Excludes unpriced usage from N request(s)` rather than claiming whole
requests were dropped.

A recorded cost of zero is a free request, not an unpriced one. Usage
without an effective group is excluded, matching what never reached
`ai_user_daily_spend`.

## Authorization

Reads go through `ExtractChatParam` plus `ResourceChat`, with no
cost-specific RBAC widening. `TestGetChatCost/MemberCanReadOwnChat`
covers a scoped `agents-access` member reading their own chat's cost,
and `MemberCannotReadOtherUsersChat` still asserts 404 for a non-owner.
Plain members without `agents-access` cannot create or read chats at
all, so they never reach this endpoint.

## Known limitation

AI Gateway data has its own retention period, 60 days by default and
configured independently of chat retention, so spend for requests older
than that is no longer reported. A chat whose gateway records have all
been purged reports zero cost, which is indistinguishable from genuinely
free usage under this contract. The endpoint documents the caveat;
#27330 documents it on the Spend Management page.

In-flight interceptions are excluded, since cost is only known once the
response is recorded. A chat's cost therefore lags the active turn by
one request.

## Rebase note

Rebased onto `main` after #27579 removed the `ai-gateway-cost-control`
experiment. The per-chat cost row is now gated on the `aibridge` feature
alone, matching how #27579 degated the other cost-control surfaces.

Susana Ferreira 3deecb481e chore: remove ai-gateway-cost-control experiment flag (#27579)
## Description

Closes
[AIGOV-443](https://linear.app/codercom/issue/AIGOV-443/remove-ai-gateway-cost-control-experiment-flag-once-feature-is-stable).

The AI Gateway cost control feature is planned for GA on the upcoming
release, so this removes the `ExperimentAIGatewayCostControl` experiment
and all of its gating. The cost control API endpoints remain gated by
the `FeatureAIBridge` license feature (the AI Governance add-on), so
this only drops the experiment layer.

## Changes

- **`codersdk/deployment.go`**: remove the
`ExperimentAIGatewayCostControl` const, its `DisplayName()` case, and
its `ExperimentsKnown` entry.
- **`enterprise/coderd/coderd.go`**: remove the
`httpmw.RequireExperiment(...)` gating from the AI cost control routes.
They keep `RequireFeatureMW(codersdk.FeatureAIBridge)`. Affected
endpoints:
  - `GET /organizations/{organization}/groups/ai/spend`
- `GET
/organizations/{organization}/groups/{groupName}/members/ai/spend`
  - `GET /organizations/{organization}/ai/spend/export`
  - `GET /groups/{group}/members/ai/spend`
  - `GET /groups/{group}/ai/spend`
- `GET/PUT/DELETE /users/{user}/ai/budget/override` and `GET
/users/{user}/ai/spend`
- **`enterprise/coderd/aibridge_test.go`**: drop the experiment from
test setup and remove the now-obsolete `RequiresExperiment`
negative-path tests.
- **Frontend (`site/src/...`)**: remove the `ai-gateway-cost-control`
experiment checks from the cost control UI (Groups pages, user dropdown)
and their stories/mocks. The feature is now driven solely by the
`aibridge` feature visibility.
- **Generated**: regenerated `coderd/apidoc/*`,
`docs/reference/api/schemas.md`, and `site/src/api/typesGenerated.ts`.

## Out of scope

The dogfood `CODER_EXPERIMENTS` config lives in a separate infra repo,
not `coder/coder`. Leaving `ai-gateway-cost-control` there is harmless:
unknown experiment values are logged as `"ignoring unknown experiment"`
at startup and otherwise ignored, so no ordering dependency or breakage.
That cleanup can be a follow-up.

<details>
<summary>Implementation notes</summary>

- Verified how unknown experiments are handled in `coderd/coderd.go`
`ReadExperiments`: unknown values produce a warning log and are inert,
so removing the definition before the dogfood config is updated is safe.
- Noticed the group `ai/budget` routes (`/groups/{group}/ai/budget`)
were already gated only by `FeatureAIBridge`, never by the experiment.
After this change all cost control routes are uniformly feature-gated,
resolving that inconsistency.
- Removed an obsolete `RequiresExperiment` subtest in
`TestUserAISpendStatus` that only asserted a 403 from the experiment
gate; with the gate gone it would no longer be blocked pre-RBAC.

Susana Ferreira d6a5c8e9f8 refactor: make user AI budget and spend endpoints consistent (#27611)
## Description

Makes the user AI cost control endpoints consistent.

## Changes

- Replaces the flat `spend_limit_micros` and `limit_source` fields on
`GET /users/{user}/ai/spend` with a nested `effective_budget`, reusing
the type behind `group_budget`. The flat pair made it possible to encode
a limit without a source.
- Renames `AIGroupBudget` to `AIBudgetLimit`, since it also carries
`user_override` limits and is no longer group-specific. The type name is
not part of the wire format.
- Moves `/users/{user}/ai/budget` to `/users/{user}/ai/budget/override`.
The endpoint only ever managed the per-user override, which the type,
the handlers, and the operation IDs all already said; the path was the
only place that didn't.

Susana Ferreira e71249a821 fix: ai cost control cap configurable AI spend limit (#27640)
## Problem

A configured AI spend limit was only validated as `gte=0`, with no upper
bound. The group spend query multiplies the per-member limit by the
number of attributed members, so a large enough limit overflows `bigint`
and fails the whole query, returning an error for every group in the
request rather than just the misconfigured one.

## Changes

- Add `MaxAISpendLimitMicros`, $1,000,000 per member per budget period.
- Reject group budgets and per-user overrides above the maximum with a
400 naming the limit.
- Bound both budget forms in the UI so they show the valid range before
submitting.

Michael Suchacz c17bed25e0 feat: wire chat lifecycle hooks into chatd (#27429)
Wires chat lifecycle hooks into chatd, gated by the
`agent-lifecycle-hooks` experiment. Part of the lifecycle hooks stack
(#27401, #27428, #27430). See `docs/admin/setup/chat-lifecycle-hooks.md`
for the consumer-facing contract.

## Summary

When a hook URL is configured, chatd dispatches `session_start`,
`user_prompt_submit`, `pre_tool_use`, `post_tool_use`, `pre_compact`,
`post_compact`, and `stop` events to the consumer and applies its
responses.

## Design

- **Stateless**: Coder stores no hook dispatch or decision state.
Delivery is at least once; consumers deduplicate on stable payload
identifiers (chat ID, event type, tool-use ID) and answer duplicates
with the same decision.
- **Admission-time prompt effects**: `user_prompt_submit` dispatches
exactly once per submission (create, send, queue, edit, subagent spawn)
and folds its effects into the stored prompt as typed message parts:
original-or-overridden user parts, then model-only `hook-context`, then
a user-visible `hook-notice`. Hook context is stripped from every
client-facing conversion; hook notices are excluded from model prompts.
The server rejects hook parts in client-submitted content.
- **Tool gating**: `pre_tool_use` allow can override tool input; deny
becomes a synthetic denied tool result, with any returned model context
persisted as a model-only transcript row so it never reaches clients.
The denial text identifies an external policy (the deployment's
lifecycle hook) as the source and marks the decision as persistent, so
the model explains the denial instead of retrying it or misreporting it
as an infrastructure failure.
- **Fail closed**: a dispatch failure rejects the triggering request or
moves the chat to the error state in the same transaction as the
affected step, so a runnable state is never published with unapproved
content.
- **Admission before persistence**: `pre_tool_use` is dispatched for the
calls the model produced, before the assistant message is stored. See
"Staged tool admission" below.
- **Fresh dispatch per tool call**: every non-provider-executed tool
call is decided by its own `pre_tool_use` dispatch; Coder never reuses
an earlier decision on the consumer's behalf. Retries re-dispatch the
same logical event.

## Structure

All hook dispatch flows through one seam: entry points build a
`chathooks.Chat` (chat identity) and a `chathooks.Message` (event
details) and call `Trigger.Trigger`, the only component that talks to
the dispatcher. The integration lives in the `coderd/x/chatd/chathooks`
subpackage, split by responsibility:

- `trigger.go`: the trigger seam; builds the wire envelope per event,
normalizes deny into a typed error, and holds the package's single
enabled-check.
- `effects.go`: pure conversion of hook results into transcript rows and
prompt parts.
- `errors.go`: failure classification (dispatch error messages, denial
mapping, tool-result dispatch-failure scanning).
- `tooluse.go`: the tool-call gate (`pre_tool_use` preflight,
`post_tool_use` payloads, applying admitted input to the step).

Server-bound glue stays in `coderd/x/chatd/hook_server.go`: the
chat-parking dispatch error handlers, the step-commit row insertion
wrappers, and the dynamic post-tool-use state loader, which depends on
chatd validation types.

This PR adopts the `codersdk/x/agenthooks` and
`coderd/x/agenthooks/dispatch` import paths introduced at the tip of
#27401; intermediate commits still reference the pre-move paths and are
not individually buildable.

## Staged tool admission

`pre_tool_use` originally ran at tool execution time, which is after the
assistant message carrying the tool call was already committed. An
`input_override` therefore had to rewrite stored message content in
place. @hugodutka pointed out that chatd treats message content as
immutable, and that the rewrite was a shortcut rather than a
requirement.

It was also a correctness problem in its own right: the rewrite only
updated the database, so the transcript could show one input while a
different one had executed.

The hook now runs before the step is persisted:

```text
provider stream ends (tool calls complete, in memory)
  -> pre_tool_use dispatch per call
  -> ONE transaction: assistant row with admitted inputs, synthetic denials, hook rows
  -> execute
```

The step is inserted once, carrying the input the tool runs with.
`UpdateChatMessageContentByID` and `Tx.UpdateMessageContent` are deleted
from #27428, so message content stays immutable.

Two consequences, both intentional:

- **Clients converge rather than wait.** Tool-call parts still stream
live, so a rewritten call briefly shows the model's proposed input
before the committed message replaces it. The chat store already clears
stream state when an assistant message arrives, so the stored input wins
with no frontend change and no added latency before tool cards appear.
- **A call already in history was already admitted.** Execution consumes
the stored input instead of dispatching a second decision, which keeps
one dispatch and one set of hook effects per call. A consumer policy
change between admission and execution applies to later calls, not to
calls already admitted.

The per-chat debug endpoint still records the provider's original tool
input. Its purpose is to report provider behavior, and it requires an
explicit per-chat debug flag; the invariant here covers the transcript.

## Configuration

Adds `chat-hook-url`, `chat-hook-secret`, `chat-hook-timeout`, and
`chat-hook-enabled` deployment options with startup validation. The
flags are hidden from `coder server --help` while the feature is
experimental; the setup guide documents them.

## Tool input validation

Built-in tool arguments reach a consumer as raw JSON with key spelling
preserved, but the tools decode those bytes with Go, which matches
struct fields case-insensitively and keeps the last match. A policy
reading `path` could therefore authorize one value while the tool
executed another, and a lone case variant such as `{"PATH":"/secret"}`
was invisible to a policy checking for `path`.

Coder now rejects a built-in tool call whose input repeats a key or
spells a schema property with different capitalization, before the
`pre_tool_use` dispatch, so a consumer is never asked to authorize bytes
whose meaning depends on the reader. Rejected calls produce an error
result the model can retry; unambiguous calls in the same batch still
run. A consumer-authored `input_override` is rechecked after the
dispatch and fails the turn closed, because the model cannot correct it.
Dynamic and MCP inputs are excluded because the client and the workspace
agent execute those calls rather than coderd.

Two paths needed more than a schema check. Execution resolves a
deprecated tool name to its canonical tool, so validation resolves
aliases first. The `edit_files` decoder also reads `search` and
`replace`, which its schema does not advertise, so those aliases are now
matched exactly and their case variants ignored.

A hook denial now returns a structured 403 carrying `kind:
"hook_denied"`, mirroring the dispatch-failure response that already
carries its own kind. Without it a client cannot tell a policy decision
apart from a generic failure, and the chat UI titled a denial "Request
failed". Adding a kind needs no migration: `ChatErrorKind` is persisted
only inside the JSONB `chats.last_error` column, whose decoder accepts
unknown kinds.

The hook docs also correct the tool-input convergence window. A batch
dispatches sequentially before the assistant row commits, so the
original input stays visible for a span that scales with the number of
tool calls in the step rather than a single hook timeout.
