## Summary
- Add experimental personal skills API helpers and an Agents settings UI
for listing, creating, editing, deleting, and importing SKILL.md
content.
- Add docs, Storybook coverage, and unit tests for backend-compatible
SKILL.md parsing.
- Address review feedback by simplifying frontmatter scalar parsing,
clarifying the UI parser scope, defaulting personal skill queries to
`me`, and patching React Query caches after create, update, and delete.
- Merge latest `main` and resolve the Agents sidebar refactor conflicts.

Removes the coder_secret Terraform integration: the data.coder_secret
consumption path through provisionerdserver → provisioner.proto →
provisioner/terraform, the dynamic-parameter secret-requirement
validation, and the workspace-update / resolve-autostart surfaces that
depended on it. This is being done due to a product/feature direction
change (see PLAT-243). User-secret CRUD (DB, REST, CLI, UI, telemetry, audit)
and the agent-manifest secret-injection path are untouched.
The provisionerd API is bumped from v1.17 to v1.18 rather than rolled
back: v1.17 shipped in v2.33.x, so user_secrets field numbers are
reserved and the changelog documents both versions.
Generated with assistance from Coder Agents.
Adds options matching new AI Gateway naming.
New options are added as alias for old options. Old options are still
working.
Old options have deprecated message.
No conflict detection was added.
Updated documentation so it mentions only new options. Added note about
old options still working.
> Various AI tools where used to create this PR
When the execute tool runs a chained shell command, the UI previously
rendered the raw string. Long chains like "cd /repo && git pull &&
git add . && git commit -m fix" were hard to scan.
A new ChatMessagePart.ParsedCommands [][]string field on tool-call
parts carries one entry per simple command, parsed in chatd from args
via mvdan.cc/sh/v3/syntax. The frontend renders the joined list ("cd,
git pull, git add, git commit") in place of the raw command, and falls
back to the raw command when the field is absent.

## Stack Context
This PR is the storage, permissions, API, and SDK layer for experimental
personal skills. #25362 has landed on `main`, so this branch is
restacked directly on `main`.
Stack order:
1. #25363 storage, permissions, API, and SDK
2. #25365 API test coverage
3. #25366 chattool and chatd integration
4. #25066 settings UI and docs
5. #25386 personal skills slash menu
## What?
Adds the `user_skills` database table, generated queries, RBAC resources
and scopes, audit resource handling, experimental user-scoped CRUD
endpoints, SDK types, and generated API/site types.
Follow-up review and restack fixes:
- Enforce a bounded personal skill description in parser and database
constraints.
- Return `403 Forbidden` for unauthorized create and update attempts.
- Return explicit conflict responses when soft-deleted users are
targeted.
- Keep user admins out of personal skills, while site owners can read
and delete but not create or update.
- Document trigger-raised constraint names and keep schema constants
covered by tests.
- Reuse `UserSkillMetadata` in the full `UserSkill` SDK response type.
- Generate user skill IDs in Go instead of relying on a database
default.
- Rebase on latest `main` and renumber the user skills migration to
`000502_user_skills`.
## Why?
Personal skills need durable user-owned storage with owner
authorization, limited site-owner moderation, and a hidden API surface
before chatd can consume them.
## Validation
- `make gen`
- `go test ./coderd/database -run '^TestUserSkillSchemaConstants$'
-count=1`
- `go test ./coderd/database/dbauthz -run
'^TestMethodTestSuite/TestUserSkills$' -count=1`
- `go test ./coderd -run '^TestPatchUserSkill$' -count=1`
- `go test ./codersdk ./coderd/database/db2sdk`
- `make lint`
- pre-commit hook on `97fd58108d`
Add frontend API methods, mocks, and form helpers for user secrets CRUD. The new client methods cover list, get, create, update, and delete requests, including URL encoding for secret names used in route paths.
Add user secret form utilities for create and update payload construction, required create field checks, and structured API validation error mapping back to form fields. User secret name validation now lives in codersdk with tests, and coderd returns field-level validation errors for create, update, and uniqueness conflicts so the frontend can show backend-owned validation results consistently.
Records reasoning start and end times on persisted reasoning
`ChatMessagePart`s so reasoning duration can be computed for stored
chats. Backend-only: no SSE changes and no frontend rendering ship in
this PR.
The `created_at` field on `ChatMessagePart` is extended to also be
present on `reasoning` parts (it previously appeared only on `tool-call`
and `tool-result`), and a new `completed_at` field is added for
`reasoning` parts.
### How timestamps are recorded
- `StreamPartTypeReasoningStart`: stamp `startedAt = dbtime.Now()` on
the active reasoning state.
- `StreamPartTypeReasoningEnd`: stamp `completedAt = dbtime.Now()` and
append both into parallel `[]time.Time` slices on `stepResult`.
- Persistence reads the slices in occurrence order (reasoning has no
provider-side ID) and applies them to the matching `ChatMessagePart` via
`buildAssistantPartsForPersist`. The first reasoning block's stamps go
onto the first reasoning part, and so on.
- `flushActiveState` flushes partial reasoning interrupted before
`StreamPartTypeReasoningEnd` with `startedAt` from the active state and
`completedAt = dbtime.Now()` at the interruption.
### Why two fields, not one?
Tool calls and results are point events. The frontend computes their
duration by subtracting the call's `created_at` from the result's
`created_at`. Reasoning is one assistant part that brackets a span, so
we record both endpoints on the part itself.
### Why not stamp in `PartFromContent`?
Same rationale as #24101: `PartFromContent` is called during both SSE
publishing and persistence. Stamping there would yield incorrect
persistence-time timestamps for reasoning blocks that finished much
earlier in the step. Instead we capture in the chatloop and apply during
persistence.
<details><summary>Implementation plan</summary>
- `codersdk/chats.go`: extend `CreatedAt`'s `variants` to include
`reasoning?`; add `CompletedAt *time.Time` with `variants:"reasoning?"`.
- `coderd/x/chatd/chatloop/chatloop.go`: extend `reasoningState` with
`startedAt`; extend `stepResult` and `PersistedStep` with parallel
`[]time.Time` reasoning slices; stamp on
`ReasoningStart`/`ReasoningEnd`; thread the slices through all
`PersistStep` call sites including the interrupt-safe path; record
partial reasoning in `flushActiveState`.
- `coderd/x/chatd/attachments.go`: walk reasoning parts in occurrence
order and apply `step.ReasoningStartedAt[i]` to `part.CreatedAt` and
`step.ReasoningCompletedAt[i]` to `part.CompletedAt`.
### Tests
- `codersdk/chats_test.go` round-trips `created_at` + `completed_at` on
reasoning parts and verifies omission when absent and partial
interrupted parts.
- `coderd/x/chatd/chatprompt/chatprompt_test.go` asserts
`PartFromContent(ReasoningContent{})` does NOT stamp timestamps.
- `coderd/x/chatd/chatloop/chatloop_test.go`
`TestRun_ReasoningTimestamps` drives a stream with two reasoning blocks
and verifies parallel slices, monotonicity, ordering, non-zero values,
and content-block ordering.
`TestRun_InterruptedReasoningFlushesTimestamps` cancels mid-reasoning
and verifies `flushActiveState` records a non-zero pair.
- `coderd/x/chatd/attachments_test.go` covers
`buildAssistantPartsForPersist` for normal interleaved reasoning,
partial (zero `completed_at`), and missing slices.

## Stack Context
This stack splits experimental personal skills into smaller reviewable
PRs. Personal skills are user-owned `SKILL.md` files stored by Coder and
injected into chatd alongside workspace skills.
Stack order:
1. #25362 personal skill resolver
2. #25363 storage, permissions, API, and SDK
3. #25365 API test coverage
4. #25366 chattool and chatd integration
5. #25066 settings UI and docs
6. #25386 personal skills slash menu
## What?
Adds the shared personal skill parser and resolver package, plus
reusable skill-name validation exported from `workspacesdk`.
The parser enforces the full personal skill contract: max raw size,
kebab-case name, max name length, and non-empty body.
## Why?
The rest of the stack needs one source-aware resolver for personal and
workspace skills, including collision handling and qualified aliases.
Keeping personal skill constraints in the parser prevents callers from
accidentally parsing invalid personal skills.
## Validation
- `go test ./coderd/x/skills ./codersdk/workspacesdk`
- pre-commit hooks on this branch
Closes
https://linear.app/codercom/issue/AIGOV-284/add-group-budgets-table-and-crud-api
## Summary
Adds the `group_ai_budgets` table and the following endpoints:
- `GET /api/v2/groups/{group}/ai/budget`
- `PUT /api/v2/groups/{group}/ai/budget`
- `DELETE /api/v2/groups/{group}/ai/budget`
Each group may have at most one budget row. If no row exists, no budget
is enforced.
### Feature gate
Added `RequireFeatureMW(FeatureAIBridge)` on the `/ai/budget` sub-route.
## RBAC
Authorization reuses `rbac.ResourceGroup` with the existing
`.InOrganization(...).WithID(...)` scoping model.
The `dbauthz` wrappers load the parent `groups` row and authorize
against it.
No new resource type is introduced. As a result, anyone with
`group:update` permissions (Owner, OrgAdmin, or UserAdmin within the
organization) can manage AI budgets for that group.
## Read access for group members
`database.Group.RBACObject()` grants `policy.ActionRead` to all members
of the group through the group ACL:
```go
func (g Group) RBACObject() rbac.Object {
return rbac.ResourceGroup.WithID(g.ID).
InOrg(g.OrganizationID).
// Group members can read the group.
WithGroupACL(map[string][]policy.Action{
g.ID.String(): {
policy.ActionRead,
},
})
}
```
Because the `GET` endpoint authorizes against the same loaded `Group`
object, any group member can call:
```text
GET /api/v2/groups/{group}/ai/budget
```
`PUT` and `DELETE` remain admin-only. The group ACL grants only
`ActionRead`, so write operations continue to require role-based
`group:update` permissions.
## Alternative considered
A dedicated `rbac.ResourceGroupAiBudget` resource would allow budget
management to be separated from general group administration.
We decided not to add that complexity for now.
Follow-up to #25004. The merged change cycles only through messages
already loaded in the in-memory chat store (page size 50). Long chats
and chats whose oldest turns have rolled out of the page lose access to
their earlier prompts in the composer's up/down arrow cycle. This PR
adds a dedicated server endpoint that returns the full prompt history,
newest first, and rewires the composer to use it.
## What changed
### Endpoint
`GET /api/experimental/chats/{chat}/prompts?limit=N`
```go
type ChatPrompt struct { ID int64; Text string }
type ChatPromptsResponse struct { Prompts []ChatPrompt }
```
- `limit`: `0..2000`. `0` (the default) is treated as the server-side
default of 500; out-of-range values return `400`. Negative values are
rejected by the SDK's `PositiveInt32` parser before reaching the
handler.
- Auth: parent-chat read in `dbauthz`, mirroring
`GetChatMessagesByChatID`.
- The SQL filters `role='user'`, `deleted=false`, `visibility IN
('user','both')`, guards the lateral with `jsonb_typeof(content) =
'array'` so legacy V0 scalar-string rows are silently skipped, then
unrolls `content` JSONB with `WITH ORDINALITY` and concatenates only
`type='text'` parts in original order via `string_agg(... ORDER BY
ordinality)`. Messages whose joined text is whitespace-only are dropped
via `HAVING ... ~ '\S'` so cycling never lands on a blank entry.
### Partial index (migration `000494`)
```sql
CREATE INDEX idx_chat_messages_user_prompts
ON chat_messages (chat_id, id DESC)
WHERE deleted = false
AND role = 'user'
AND visibility IN ('user', 'both');
```
The partial WHERE matches the query's filter exactly and the key order
matches `ORDER BY id DESC`, so the planner gets both the filter and the
ordering from the index without a sort step.
`EXPLAIN ANALYZE` on a synthetic 51-chat × 5,000-message dataset (≈260k
rows, 10k user prompts in the target chat, `random_page_cost=1.1`):
| | Plan | Buffers hit | Time |
|---|---|---|---|
| Without index | `Index Scan Backward using chat_messages_pkey`,
**250,848 rows removed by filter** | 6,683 | 32.4 ms |
| With index | `Index Scan using idx_chat_messages_user_prompts`, no
filter | 38 | 1.3 ms |
≈25× faster, 175× fewer buffer hits.
### Frontend
- `chatPromptsKey` / `chatPromptsQuery` factories in
`site/src/api/queries/chats.ts` (`staleTime: 30s`, `enabled: chatId !==
""`, asks the server for 500 prompts).
- `ChatPageContent.tsx` replaces the in-memory derivation with
`useQuery(chatPromptsQuery(chatId ?? ""))`. The composer's existing
`cycleHistorySnapshotRef` anchors the in-flight cycle so a refetch
arriving mid-cycle cannot shift the indexed prompt out from under the
user.
- `getEditableUserMessagePayload` now concatenates user-message text
parts verbatim, mirroring the server's `string_agg(part->>'text', ''
ORDER BY ordinality)`, instead of routing through the streaming-oriented
`parseMessageContent` / `appendText` pipeline (which drops
whitespace-only chunks — correct for assistant streams, wrong for a
user's persisted message). This keeps the cycle and the edit path in
agreement on the same message. File blocks are still pulled separately
via
`parseMessageContent(...).blocks.filter(isEditableUserMessageFileBlock)`.
- Cache invalidation in `createChatMessage.onSuccess`,
`editChatMessage.onSettled`, and `useChatStore.upsertCacheMessages`
(only when an upserted message has `role === "user"`).
- Page-level stories pre-seed `chatPromptsKey(CHAT_ID)` from the same
`messagesData` to keep them offline.
## Tests
- New `TestGetChatUserPrompts` in `coderd/exp_chats_test.go` with five
subtests:
- `NewestFirstFiltering` — multi-part concatenation, non-text parts
skipped, whitespace-only filtered, soft-deleted excluded, `model`-only
visibility excluded, assistant-role excluded by `cm.role = 'user'`,
legacy V0 scalar row silently excluded by the `jsonb_typeof` guard,
ordering newest first.
- `LimitClampsResults` — explicit `limit=2` returns the two newest
prompts.
- `InvalidLimitRejected` — `limit=5000` is `400 Bad Request`.
- `NotFoundForOtherUsers` — a separate user in the same org gets `404`,
not the prompts.
- `EmptyResultIsJSONArray` — zero-message chat and assistant-only chat
both return `Prompts: []` (non-nil, empty).
- New unit test in `messageParsing.test.ts` asserting that
`getEditableUserMessagePayload(["hello", " ", "world"])` returns `"hello
world"`, locking in the agreement with the SQL `string_agg`.
- `dbauthz_test.go` adds the
`MethodTestSuite.TestChats/GetChatUserPromptsByChatID` entry, asserting
parent-chat `policy.ActionRead`.
- `pnpm test src/pages/AgentsPage` — 1159 passed, 2 skipped.
- `make gen` produces no diff.
## Manual verification
Seeded a dev chat with Claude Sonnet 4.6 via the aibridge Anthropic
provider and posted 20 user prompts end-to-end. Verified that the
`/prompts` endpoint returns 20 rows newest-first, that `limit=10` clamps
correctly, that `limit=0` uses the server default of 500, and that the
up/down keyboard cycle in the composer walks the same sequence (and
reverses correctly back to the empty draft).
## Out of scope
- Cross-chat history.
- Per-user opt-out for the cycle.
- File-reference / attachment cycling — the cycle continues to reproduce
plain text only, by design.

# CODAGT-319 Follow-up — Dedicated `/prompts` endpoint
## Context
The merged feature ([#25004](https://github.com/coder/coder/pull/25004)
/ [d32842f](https://github.com/coder/coder/commit/d32842f)) cycles only
through messages already loaded in the in-memory chat store, which is
capped at the first 50 messages of the current page. Long chats and
chats whose oldest turns have rolled out of the page can no longer
recall their full prompt history. This follow-up exposes a dedicated
server endpoint that returns the user-authored prompts in a chat, newest
first, and rewires the composer to use it.
## Design
### Endpoint
`GET /api/experimental/chats/{chat}/prompts?limit=N`
Returns:
```go
type ChatPrompt struct {
ID int64
Text string
}
type ChatPromptsResponse struct {
Prompts []ChatPrompt
}
```
- `limit`: `0..2000`. `0` (the default) → server-side default of 500.
The wire-level default is encoded in SQL as `COALESCE(NULLIF($limit, 0),
500)`. Negatives are rejected upstream by `PositiveInt32`; the handler
only caps the upper bound.
- Auth: parent-chat read in `dbauthz`, mirroring
`GetChatMessagesByChatID`.
- Listed under the experimental router so we can iterate without API
guarantees.
### SQL
The query lives in `coderd/database/queries/chats.sql` as
`GetChatUserPromptsByChatID`:
- Filters `role='user'`, `deleted=false`, `visibility IN
('user','both')` to mirror the composer's "what the user actually typed
and can re-send" contract.
- Guards the lateral with `jsonb_typeof(content) = 'array'` so legacy V0
rows whose content is a scalar JSON string (predates migration `000434`)
are silently excluded instead of raising `"cannot extract elements from
a scalar"`.
- Unrolls `content` JSONB with `jsonb_array_elements WITH ORDINALITY`
and concatenates only `type='text'` parts, preserving original order via
`string_agg(... ORDER BY ordinality)`.
- Casts the result to `text` so sqlc emits a `string` field instead of
`[]byte`.
- Drops whitespace-only prompts via `HAVING string_agg(...) ~ '\S'` so
cycling never lands on a blank entry.
- Orders by `cm.id DESC` (`id` is a sequence, so this is "newest first"
without relying on `created_at`).
### Index
New partial index added in migration `000494`:
```sql
CREATE INDEX idx_chat_messages_user_prompts
ON chat_messages (chat_id, id DESC)
WHERE deleted = false
AND role = 'user'
AND visibility IN ('user', 'both');
```
The partial WHERE clause matches the query's filter exactly, so the
planner can use the index for both filtering and ordering without a sort
step.
### Frontend
- `chatPromptsKey(chatId)` and `chatPromptsQuery(chatId)` factories in
`site/src/api/queries/chats.ts`. `staleTime: 30s`, `enabled: chatId !==
""`. Asks the server for 500 prompts (well below the 2000 max, plenty
for the cycle).
- `ChatPageContent.tsx` replaces the in-memory derivation with
`useQuery(chatPromptsQuery(chatId ?? ""))`. The composer's
`cycleHistorySnapshotRef` already takes a stable snapshot at cycle
entry, so a refetch arriving mid-cycle cannot shift the indexed prompt
out from under the user.
- `getEditableUserMessagePayload` extracts the edit-path text from raw
user-message parts (filter `type === "text"`, join verbatim) instead of
going through `parseMessageContent` / `appendText`, which is built for
assistant streams and intentionally drops whitespace-only chunks.
Without this, cycling and clicking Edit on the same message could
produce different draft text for messages with whitespace-only
interleaved text parts.
- Cache invalidation: `createChatMessage.onSuccess`,
`editChatMessage.onSettled`, and `useChatStore.upsertCacheMessages`
(when at least one upserted message has `role === "user"`) all
invalidate `chatPromptsKey(chatId)`.
### Tests
- `TestGetChatUserPrompts` (`coderd/exp_chats_test.go`) covers:
- `NewestFirstFiltering` — multi-part concatenation, non-text parts
skipped, whitespace-only filtered, soft-deleted excluded, `model`-only
visibility excluded, assistant-role excluded by `cm.role = 'user'`,
legacy V0 scalar row silently excluded by the `jsonb_typeof` guard,
ordering newest first.
- `LimitClampsResults` — explicit `limit=2` returns the two newest
prompts.
- `InvalidLimitRejected` — `limit=5000` is `400 Bad Request`.
- `NotFoundForOtherUsers` — a separate user in the same org gets `404`,
not the prompts.
- `EmptyResultIsJSONArray` — zero-message chat and assistant-only chat
both return `Prompts: []` (non-nil, empty).
- `messageParsing.test.ts` adds a unit test asserting that
`getEditableUserMessagePayload(["hello", " ", "world"])` returns `"hello
world"`, locking in the agreement with the SQL `string_agg`.
- `dbauthz_test.go` adds the
`MethodTestSuite.TestChats/GetChatUserPromptsByChatID` entry, asserting
the parent-chat `policy.ActionRead`.
## Out of scope
- Cross-chat history.
- Per-user opt-out for the cycle.
- File-reference / attachment cycling — the cycle still reproduces plain
text only, by design.

Part 1: Backend portion of a change broken into 2 PRs.
Part 2: #25077
Adds three new UserAppearanceSettings fields (theme_mode, theme_light,
theme_dark) on top of the existing theme_preference and terminal_font.
Replaces GetUserThemePreference and GetUserTerminalFont with a single
GetUserAppearanceSettings aggregate query. The PUT handler is wrapped in
db.InTx so sync-mode's mode + slot writes can never half-apply.
Adds `dynamicparameters.EvaluateSecretMismatch` as a shared helper on
top of the existing renderer, then wires it into the resolve-autostart
handler so the UI can surface unsatisfied `coder_secret` requirements in
a template alongside parameter mismatch for autostart.
The lifecycle executor changes will land in a follow-up that depend
on this helper. The UI changes that consume the new `secret_mismatch`
field is also a follow-up.
Generated with assistance from Coder Agents.
Editing a previous user message and selecting a different model in the
picker silently kept using the original model: the selection was dropped
on the frontend, in the SDK, and in the backend, so both the replacement
user message and the assistant turn that followed ran against the old
model.
Plumb the selected model through all three layers (`AgentChatPage`,
`codersdk.EditChatMessageRequest`, `chatd.EditMessageOptions` /
`Server.EditMessage`), defaulting to the original message's model when
the client does not specify one. The existing `InsertChatMessages` CTE
already advances `chats.last_model_config_id` when the inserted
message's model differs, so the assistant turn picks up the new
selection without further changes. The new model is validated inside the
transaction, so an unknown ID rolls the edit back and returns a 400
`Invalid model config ID.`, mirroring the `SendMessage` path.

# CODAGT-345: Editing an earlier message cannot change model
## Problem
When editing a previous user message in a chat, the user can change the
model in the model picker, but the backend keeps using the original
message's model. The model selection is dropped at three layers:
1. **Frontend:** `AgentChatPage.tsx`'s edit branch builds an
`EditChatMessageRequest` that omits `model_config_id`. The new-message
branch (a few lines below) does include it.
2. **SDK:** `codersdk.EditChatMessageRequest` has no `ModelConfigID`
field at all.
3. **Backend:** `chatd.EditMessageOptions` has no model field, and
`Server.EditMessage` always copies the original message's
`ModelConfigID` into the replacement message.
Once the replacement user message is inserted with the original model,
the `InsertChatMessages` CTE leaves `chats.last_model_config_id`
unchanged, so the assistant turn that follows runs against the old
model.
## Fix
Plumb the selected model through all three layers, defaulting to the
original message's model when the client doesn't override it. This
mirrors the `SendMessage` path, which already accepts a
`model_config_id` and validates it via
`resolveSendMessageModelConfigID`.
### Backend
- `codersdk/chats.go`: add `ModelConfigID *uuid.UUID` to
`EditChatMessageRequest`.
- `coderd/x/chatd/chatd.go`:
- Add `ModelConfigID uuid.UUID` to `EditMessageOptions`.
- In `EditMessage`, after fetching the edited message, resolve the
model: if `opts.ModelConfigID != uuid.Nil`, validate it exists with
`tx.GetChatModelConfigByID` (using `chatdModelConfigLookupContext`),
otherwise keep `editedMsg.ModelConfigID.UUID`. Pass the resolved ID into
`newChatMessage(...)`.
- Reuse the existing `ErrInvalidModelConfigID` sentinel.
- `coderd/exp_chats.go` (`patchChatMessage`):
- Read `req.ModelConfigID` (nil-safe), pass into
`chatd.EditMessageOptions`.
- Add a `case xerrors.Is(editErr, chatd.ErrInvalidModelConfigID)` arm
returning 400 `Invalid model config ID.`, matching the
`postChatMessages` handler.
### Frontend
- `site/src/pages/AgentsPage/AgentChatPage.tsx`:
- In the edit branch, set `model_config_id: effectiveSelectedModel ||
undefined` on the `EditChatMessageRequest`.
- On success, persist the chosen model to `lastModelConfigIDStorageKey`
so the next chat from this browser keeps the same default. Mirrors the
new-message branch.
### Generated
- `make site/src/api/typesGenerated.ts` and `make
coderd/apidoc/swagger.json` produce the updated `EditChatMessageRequest`
schema in `typesGenerated.ts`, `coderd/apidoc/{docs.go,swagger.json}`,
and `docs/reference/api/{chats.md,schemas.md}`.
## Tests
- `coderd/x/chatd/chatd_test.go`:
- `TestEditMessageWithModelConfigOverride`: edit with a different model
-> replacement message and `chats.LastModelConfigID` use the new model.
- `TestEditMessagePreservesModelConfigByDefault`: edit without
`ModelConfigID` -> original model preserved.
- `TestEditMessageRejectsUnknownModelConfig`: passes a random UUID ->
`ErrInvalidModelConfigID`, original message still present,
`LastModelConfigID` unchanged (rollback).
- `coderd/exp_chats_test.go` (under `TestPatchChatMessage`):
- `ChangesModel`: end-to-end via SDK; `edited.Message.ModelConfigID` and
`chat.LastModelConfigID` both match the new model.
- `InvalidModelConfigID`: random UUID -> 400 `Invalid model config ID.`.

Adds an Agents General setting to require Cmd/Ctrl+Enter before sending
chat messages. When enabled, plain Enter inserts a newline in agent chat
inputs while the send button remains available.
The preference is now persisted server-side through
`/api/v2/users/{user}/preferences`, alongside the existing user
preference settings, and is applied to both the create-agent input and
existing chat composer. Storybook and API coverage verify the setting,
keyboard behavior, validation, and persistence.

Stream advisor output into the advisor tool card while the nested
advisor call is still running.
This keeps the advisor implementation intentionally advisor-specific:
the parent model still receives the same final structured tool result,
while the frontend receives transient `tool-result.result_delta` parts
to render partial advisor text in the expanded card. The final persisted
chat history remains unchanged.

- Forward those deltas through `chatadvisor.Tool` with the parent
advisor tool call ID.
- Emit transient `ChatMessagePartTypeToolResult` websocket parts with
`ResultDelta` from `chatd`.
- Add `result_delta` to the generated tool-result TypeScript variant.
- Accumulate tool result deltas in frontend stream state and keep the

Closes https://github.com/coder/coder/issues/13112
**Breaking Change**: Removed status code `StatusNotModified` when no
diffs occur in a patch. Now the patch is always applied and a template
is always returned.
Closes
[CODAGT-317](https://linear.app/codercom/issue/CODAGT-317/pr-workspaces-sometimes-require-name-confirmation-to-delete).
## Problem
The `/agents` archive-and-delete molly-guard (typing the workspace name)
was firing for chats that had clearly created their own workspace. The
heuristic in `resolveArchiveAndDeleteAction` decides whether
confirmation is needed by comparing the workspace's `created_at` against
the chat's `created_at`:
```ts
return new Date(workspaceCreatedAt) >= new Date(chatCreatedAt);
```
That assumption breaks for **prebuilt workspaces**.
`ClaimPrebuiltWorkspace` rewrites `owner_id`, `name`, `updated_at`,
`last_used_at`, etc., but **never touches `created_at`**, which still
reflects when the prebuild was provisioned by the reconciler, often
hours before the chat exists. Result: every prebuild-claimed workspace
looks pre-existing, so the molly-guard fires.
Concrete example from a real chat:
| Field | Value |
|---|---|
| `chat.created_at` | `2026-05-07T15:12:23Z` |
| `workspace.created_at` (provision) | `2026-05-07T14:22:24Z` |
| `latest_build.created_at` (claim) | `2026-05-07T15:19:09Z` |
`14:22:24 < 15:12:23` so `isWorkspaceAutoCreated` returned false even
though the chat issued the claim.
## Fix (frontend-only)
Derive the moment a workspace was acquired from existing build history
rather than relying on `workspace.created_at`:
- Build #1 initiator = prebuilds system user → workspace was a prebuild
→ use `build_2.created_at` (the claim build) as the acquisition time.
- Build #1 initiator = real user → workspace was created from scratch →
use `workspace.created_at` (unchanged behavior).
- Unclaimed prebuild or no build history → return `null` (force
confirmation; safe degradation for a destructive flow).
The resolver fetches the build list via the existing
`getWorkspaceBuilds` endpoint when the dialog might fire. No new column,
no migration, no schema change. Works retroactively for all existing
claimed prebuilds; no backfill needed.
The prebuilds system user UUID is exposed via
`codersdk.PrebuildsSystemUserID` and typegen'd to `typesGenerated.ts`.
`coderd/database.PrebuildsSystemUserID` parses that constant via
`uuid.MustParse` so the two cannot drift; if the codersdk literal ever
changes, package init fails fast.
## History
The first draft of this PR added a `workspaces.claimed_at` column
populated by `ClaimPrebuiltWorkspace`. After review feedback from
@johnstcn pointing out that the same fact is already implicit in build
history, I pivoted to the frontend-only approach. Subsequent review
notes consolidated the prebuilds system user UUID into a single
typegen'd constant.
## Why not the other open PRs
- **#25055** (`chatKey` cache fallback) only fixes a different
cache-miss path; it explicitly notes it does not address `created_at <
chat.created_at`.
- **#25053** (`chats.workspace_auto_created` boolean) puts the truth on
the wrong side of the schema: "this workspace was claimed at time T" is
a property of the workspace, not the chat. The MCP plumbing it adds is
also unnecessary now that the same answer is available from build
history.
## Test plan
- `pnpm vitest run --project=unit
src/pages/AgentsPage/utils/agentWorkspaceUtils.test.ts` — 40/40 pass;
new cases cover prebuild claim before/after chat, unclaimed prebuild,
missing-build-history fallback, and the fetch-skip when the chat is not
in cache.
- `pnpm lint:types`, `pnpm check`, `make pre-commit`.

# Summary
Implements
https://linear.app/codercom/issue/AIGOV-282/add-ai-model-price-table-and-seed-generator
This PR lays the groundwork for AI Bridge cost controls (per the AI
Governance RFC). It adds the foundation needed for future cost tracking:
a place to store per-model token prices, a way to keep those prices in
sync with upstream pricing data, and a startup mechanism that ensures
every deployment has prices loaded before AI Bridge starts processing
requests.
The price data comes from [models.dev](https://models.dev/), a
community-maintained catalogue of AI provider pricing. A generator
script fetches the latest prices, filters to Anthropic and OpenAI for
now, and produces a seed file checked into the repository.
On every server startup the seed is applied to the database, so new
releases automatically pick up any price corrections that landed since
the previous one. Existing rows are overwritten with the latest prices;
rows for models no longer in the seed are left untouched.
# Batching the AI model price seed: three approaches
Context: at server startup we seed the `ai_model_prices` table from an
embedded JSON price book (~70 rows today, will grow as we add providers,
potentially 4000+).
Each row is:
```text
(provider, model, input_price, output_price, cache_read_price, cache_write_price)
```
Any of the four price columns can be:
- `NULL` → “price unknown for this dimension”
- explicit `0` → “free”
The batch must be an UPSERT so re-running is idempotent and existing
rows pick up new prices.
We considered three implementations.
---
## Approach 1 — Per-row UPSERT in a Go loop
```go
for _, row := range rows {
if err := db.UpsertAIModelPrice(ctx, database.UpsertAIModelPriceParams{
Provider: row.Provider,
Model: row.Model,
InputPrice: nullInt64(row.InputPrice),
// ...
}); err != nil {
return err
}
}
```
### Pros
- Trivial.
- NULL handling falls out naturally from `sql.NullInt64`.
### Cons
- `N` round-trips per seed.
- With ~70 rows that means ~70 statement executions on every startup,
even inside a transaction.
- Doesn't scale gracefully as the price book grows, potentially 4000+.
---
## Approach 2 — `UNNEST` with parallel arrays
Pass each column as a separate Go slice. Postgres unnests them in
parallel into a virtual table, then `INSERT ... SELECT`.
```sql
INSERT INTO ai_model_prices (
provider,
model,
input_price,
output_price,
cache_read_price,
cache_write_price
)
SELECT
UNNEST(@providers::text[]),
UNNEST(@models::text[]),
NULLIF(UNNEST(@input_prices::bigint[]), -1),
NULLIF(UNNEST(@output_prices::bigint[]), -1),
NULLIF(UNNEST(@cache_read_prices::bigint[]), -1),
NULLIF(UNNEST(@cache_write_prices::bigint[]), -1)
ON CONFLICT (provider, model) DO UPDATE SET
input_price = EXCLUDED.input_price,
output_price = EXCLUDED.output_price,
cache_read_price = EXCLUDED.cache_read_price,
cache_write_price = EXCLUDED.cache_write_price,
updated_at = NOW();
```
Go side: flatten rows into six parallel slices.
Use a sentinel (`-1`) for “missing”, since `lib/pq` can't encode `NULL`
into a `bigint[]` element.
```go
providers := make([]string, len(rows))
models := make([]string, len(rows))
inputs := make([]int64, len(rows))
outputs := make([]int64, len(rows))
cacheR := make([]int64, len(rows))
cacheW := make([]int64, len(rows))
for i, r := range rows {
providers[i] = r.Provider
models[i] = r.Model
inputs[i] = -1
if r.InputPrice != nil {
inputs[i] = *r.InputPrice
}
outputs[i] = -1
if r.OutputPrice != nil {
outputs[i] = *r.OutputPrice
}
cacheR[i] = -1
if r.CacheReadPrice != nil {
cacheR[i] = *r.CacheReadPrice
}
cacheW[i] = -1
if r.CacheWritePrice != nil {
cacheW[i] = *r.CacheWritePrice
}
}
return db.UpsertAIModelPrices(ctx, database.UpsertAIModelPricesParams{
Providers: providers,
Models: models,
InputPrices: inputs,
OutputPrices: outputs,
CacheReadPrices: cacheR,
CacheWritePrices: cacheW,
})
```
### Pros
- Single round-trip.
### Cons
- The generated `sqlc` params become plain `[]int64`, which can't
represent `NULL`.
---
## Approach 3 — `jsonb_array_elements` over a single `@seed::jsonb`
(chosen)
Pass the raw seed JSON as one parameter; let Postgres expand and parse
it.
```sql
INSERT INTO ai_model_prices (
provider,
model,
input_price,
output_price,
cache_read_price,
cache_write_price
)
SELECT
elem->>'provider',
elem->>'model',
(elem->>'input_price')::bigint,
(elem->>'output_price')::bigint,
(elem->>'cache_read_price')::bigint,
(elem->>'cache_write_price')::bigint
FROM jsonb_array_elements(@seed::jsonb) AS elem
ON CONFLICT (provider, model) DO UPDATE SET
input_price = EXCLUDED.input_price,
output_price = EXCLUDED.output_price,
cache_read_price = EXCLUDED.cache_read_price,
cache_write_price = EXCLUDED.cache_write_price,
updated_at = NOW();
```
Go side reduces to:
```go
return db.UpsertAIModelPrices(ctx, seedJSON)
```
### Pros
- Single round-trip.
- NULLs fall out naturally:
- `(elem->>'cache_write_price')::bigint` becomes `NULL`
- no sentinels
- The seed is already JSON:
- Existing precedent:
- `jsonb_array_elements` is already used elsewhere in the codebase
### Cons
- Less type-safe at the SQL boundary than `UNNEST`
- Slightly less standard than `UNNEST`
- Readers need familiarity with:
- `jsonb_array_elements`
- `->>` extraction syntax
- Postgres pays JSON parse cost
- negligible at our scale
---
---
# Decision
We picked Approach 3.
It collapses the round-trips like `UNNEST` does, but without:
- nullable-array workarounds
- sentinel values
Anthropic rejects inline images over 5,242,880 bytes, but our upload
endpoint accepts images up to 10 MiB — so 5–10 MiB images were
reaching the provider and failing. This adds two layers of
protection: the browser resizes oversized images before upload, and
the server rejects any that still slip through before an upstream
request is issued.
Client-side resizing uses `createImageBitmap` with
`resizeWidth`/`resizeHeight` to clamp the decoded bitmap at decode
time, then iteratively shrinks on an `OffscreenCanvas` (falling back
to `HTMLCanvasElement`) until the output fits the applicable budget.
Anthropic (and Bedrock-hosted Claude — fantasy's bedrock provider is
a thin wrapper around the Anthropic client) uses a ~5 MiB budget;
other providers use a ~10 MiB budget to stay under the server cap.
Doing the resize in the browser avoids decoding attacker-controlled
image bytes in `coderd` (image-bomb DoS surface).
Server-side, `chatFileResolver` now takes a provider string and
looks up the inline-image cap via a new
`chatprovider.InlineImageByteCap`
helper; oversized `image/*` files for capped providers are rejected
with a pre-classified `chaterror` before the SDK call. The backstop
fires for older clients, direct API callers, or any image that was
committed to the composer before the user switched to a stricter
provider.
Attachments commit to composer state synchronously with a new
`"processing"` `UploadState` so paste+Enter can't dispatch before
the resize finishes; the `"uploading"` send gate now covers both
states. Dismissed-while-resizing attachments are tracked in a
`WeakSet` so a late swap can't resurrect a removed file.
Closes CODAGT-215
## Summary
When a workspace build fails because the user is over their group quota,
the chat tools currently surface the failure as a bare `"workspace build
failed: insufficient quota"` string with no machine-readable error code
and no visibility into the user's current usage. Agents and the UI
cannot distinguish quota failures from any other Terraform error, so
users see an opaque message and have no clear path to recovery.
This PR tags quota failures with a typed error code at the source and
propagates it through the chat tool layer so callers can react to it
explicitly.
Relates to CODAGT-20
## Changes
**Provisioner runner**
- Add `InsufficientQuotaErrorCode = "INSUFFICIENT_QUOTA"` and set it
explicitly at the `commitQuota` failure site via a new
`failedWorkspaceBuildfCode` helper, so `provisioner_jobs.error_code` is
populated only on the genuine quota path. The substring matcher used for
externally produced sentinels (e.g. `"missing parameter"`, `"required
template variables"`) is intentionally not extended; provider errors
that happen to mention "insufficient quota" stay classified as generic
build failures.
**SDK and API contract**
- Add `JobErrorCodeInsufficientQuota` and a
`JobIsInsufficientQuotaErrorCode` helper to `codersdk`.
- Extend the swagger `enums` tag on `ProvisionerJob.ErrorCode` to
include `INSUFFICIENT_QUOTA`.
- Regenerate `coderd/apidoc`, `docs/reference/api/*`, and
`site/src/api/typesGenerated.ts`.
**chattool create_workspace / start_workspace**
- `waitForBuild` now returns a typed `*workspaceBuildError` carrying
both the message and the `JobErrorCode`, instead of a bare error string.
- New `quotaerror.go` introduces a structured `quotaErrorResult` (with
`error_code`, `title`, `message`, `build_id`, and optional `quota`) and
a best-effort `workspaceQuotaDetails` lookup that wraps owner
authorization internally and fetches `credits_consumed` and `budget`
from the database. Quota lookup failures (including authorization
failures) never block the failure payload.
- On quota-coded build failures, both `create_workspace` and
`start_workspace` now return the structured response (with the recovery
guidance inlined into `message`) instead of the bare `"insufficient
quota"` string. This applies to all three failure paths: post-creation,
an in-progress existing build, and a freshly triggered start build.
Non-quota build failures continue to use the existing
`buildToolResponse` / `newBuildError` path.
- Owner authorization is wrapped only on the call sites that need it
(the `CreateFn` and `StartFn` invocations and the quota-detail lookup),
so idempotent fast paths (already running, already in progress,
existing-workspace early returns) do not pay for an extra RBAC
round-trip or fail when role lookup is transient.
## Out of scope
- No changes to quota math, allowances, or bypass behavior.
- No automatic retries.
- No new quota-inspection tools and no changes to MCP
`coder_create_workspace` (which returns immediately and never observed
the build outcome here).
- No frontend UI changes; those will land in a follow-up PR that
consumes the new `INSUFFICIENT_QUOTA` code.
Previously, the `CreateWorkspaceBuild` toolsdk tests only exercised a
start where the workspace's prior template version was also the
template's active version, so they did not prove that a plain start
keeps using the previously built version.
Replace that tautological coverage with an isolated fixture that
advances the template's active version and asserts a start without
`TemplateVersionID` still reuses the prior build's version.
Persists the agent-generated turn-end summary on `chats` and shows it as
the Agents sidebar subtitle when present, falling back to the model
name. Errors still take precedence.
> Mux is acting on Mike's behalf.
## What changes
**Storage.** New nullable `last_turn_summary` column on `chats`
(migration `000486`). New `UpdateChatLastTurnSummary` query normalizes
blank/whitespace input to `NULL`, preserves `updated_at` (so the chat
does not jump to the top of the sidebar on summary writes), and uses an
`expected_updated_at` stale-write guard so an older async summary cannot
overwrite a newer turn.
**Backend.** `coderd/x/chatd/chatd.go` decouples summary generation from
webpush. Generated summaries persist for completed parent turns even
when webpush is unconfigured or has no subscriptions. The same generated
text is reused as the webpush body when webpush is configured, so the
summary model is not called twice. Generic fallback push text is no
longer persisted; it clears any stale summary instead.
Error/interrupt/pending-action terminal paths clear `last_turn_summary`
for the latest turn.
**Frontend.** `AgentsSidebar.tsx` subtitle priority is now `errorReason
|| lastTurnSummary || modelName`, normalized via the existing
`asNonEmptyString` helper from `blockUtils.ts`.
## Tests
- `TestUpdateChatLastTurnSummary` (database): success,
whitespace-to-NULL, stale guard rejects, `updated_at` preserved.
- `TestUpdateLastTurnSummaryRejectsStaleWrites` (chatd internal): direct
stale-`expected_updated_at` test.
- `TestSuccessfulChatPersistsTurnSummaryWithoutWebPush`: persistence
works without webpush subscriptions.
- `TestSuccessfulChatSendsWebPushWithSummary`: same generated text
drives both DB and push body.
-
`TestSuccessfulChatSendsWebPushFallbackWithoutSummaryForEmptyAssistantText`:
fallback text is not persisted.
- `TestErroredChatClearsLastTurnSummaryAndSendsWebPush`: error path
clears the field.
- `TestInterruptChatDoesNotSendWebPushNotification`: interrupt path
clears the field, no push fires.
- `AgentsSidebar.test.tsx`: subtitle priority for summary-present,
error-wins, no-summary fallback, whitespace fallback.
- `AgentsSidebar.stories.tsx`: `ChatWithTurnSummary` and
`ChatWithTurnSummaryAndError`.
## Notes
- No backfill. Existing chats keep showing the model name until their
next turn completes.
- Parent chats only in this iteration; the field is rendered on any
`Chat` if a future change extends generation to children.
- Decoupling generation from webpush adds quickgen model calls for
completed parent turns that previously skipped generation when no
subscriptions existed. Existing parent-only, assistant-text-present,
`PushSummaryModel` configured, and bounded-timeout gates keep this
behavior bounded.
Moves the chat error kind taxonomy from `coderd/x/chatd/chaterror` into
`codersdk.ChatErrorKind` and types `ChatError.Kind` /
`ChatStreamRetry.Kind` so generated TypeScript exposes an SDK-owned
union, including `usage_limit`. Backend chat classification now
references the SDK constants directly while preserving the existing JSON
string values.
Keeps chat usage-limit admission failures on their existing 409 response
shape. The frontend maps structured usage-limit responses to the
SDK-owned `usage_limit` kind, uses generated `TypesGen.ChatErrorKind`
directly, and removes the local string union and alias.
> Mux is acting on Mike's behalf.
Adds configurable retention for chat debug data, including the purge
query, updated_at index, site config, experimental API, SDK types,
frontend lifecycle setting, and docs.
The purge deletes debug runs older than the configured retention window
and relies on existing cascades to delete steps. The default retention
is 30 days, and setting the value to 0 disables the purge.
