`watchChatGit` proxies a live websocket to the workspace agent's git
watcher (`/api/v0/git/watch`), streaming repository diffs back through
the chat stream. Before this change it only enforced `chat:read` (via
`ExtractChatParam`) plus an implicit `workspace:read` from the dbauthz
wrapper on `GetWorkspaceAgentsInLatestBuildByWorkspaceID`. The sibling
`watchChatDesktop` handler already fetches the workspace and requires
`policy.ActionApplicationConnect` or `policy.ActionSSH` before dialing.
Built-in roles like **Template Admin** and **Org Admin** grant
`workspace:read` without SSH/ApplicationConnect, and **Owner** also
loses both under `DisableOwnerWorkspaceExec`. A chat owner whose
exec-level workspace access was revoked *after* the chat was bound could
therefore keep streaming repository content from the workspace agent
through the chat's git-watch endpoint.
Mirror `watchChatDesktop`: fetch the workspace and require
`ApplicationConnect || SSH` before any agent-tunnel activity. Adds one
real-coderdtest regression test (`TestWatchChatGitAuthz`) that demotes
the chat's owner to template-admin after binding and asserts the
git-watch endpoint returns 403; the mock-based `TestWatchChatGit` in
`coderd/workspaceagents_internal_test.go` continues to cover the
no-workspace / disconnected-agent / websocket-proxy paths.
Fixes CODAGT-184.
GetChildChatsByParentIDs sorted created_at ASC, but the cache
helper appended new children to the end. On refetch the API and
cache agreed on oldest-first, putting the just-created child at
the bottom. Users expect newest first, matching the root-chat
sidebar convention.
- SQL: change child sort to created_at DESC, id DESC.
- Cache: prepend instead of append in addChildToParentInCache
(renamed from appendChildToParentInCache to avoid leaking
position semantics).
- Test: update ordering assertion to expect newest-first.
Refs #24404
GetChats now returns only root chats (parent_chat_id IS NULL).
A new GetChildChatsByParentIDs query fetches children for visible
roots and embeds them in each parent's Children field. The
singular getChat endpoint does the same.
Archive invariant is one-way: parent archived implies child
archived. Parent archive/unarchive cascades via root_chat_id.
Individual child archive is permitted; child unarchive while the
parent is archived is rejected atomically (row lock on child,
re-read parent inside the transaction). Embedded children are
filtered by the caller's archive state so individually-archived
children stay hidden from active-parent views.
Gitsync MarkStale uses GetChatsByWorkspaceIDs directly;
MarkStaleParams.OwnerID removed (dead after the switch).
Frontend: buildChatTree reads from the embedded children field,
WebSocket handlers route child events into the parent's children
array, and archiving a child strips it from the parent cache.
Modifies chatloop error classification behaviour to treat the following as retryable:
* HTTP/2 `force closed`
* GOAWAY
* use of closed network connection
* Modfies user-facing retry banner to show "<provider> is temporarily
unavailable."

## Description
Makes AWS Bedrock credentials optional. When `AccessKey` and
`AccessKeySecret` are not set, AI Bridge falls back to the AWS SDK
default credential chain, which supports IAM Roles (instance profiles,
IRSA, ECS task roles), SSO, shared credentials files, and environment
variables.
This allows AI Bridge to authenticate with AWS Bedrock using:
- Permanent credentials (access key + secret) as before
- IAM Roles, shared config files, environment variables, SSO, etc, via
the SDK default credential chain

- Replaces the hard-coded 500ms reconnect timer for dialing chat relays with exponential backoff via `coder/retry`.
- `dialRelay` drops the `codersdk.ExperimentalClient.StreamChat` wrapper
and calls `websocket.Dial` directly so we can capture
`*http.Response.StatusCode` without parsing error strings.
- Adds `RelayDialError` that exposes the HTTP status from `websocket.Dial`
- Modifies retry logic: 401/403 tear the stream down immediately, 5xx/network/timeouts retry
then tear down on cap. Outer stream closes cleanly so the browser SDK
reconnects with a fresh cookie.
- Retry state resets on successful dial and on target-worker change, not
on every `closeRelay()`.

Agents can already see workspace files and take screenshots, but users could not download those artifacts from chat. This PR adds durable chat attachments to chatd. `attach_file`, explicit `computer` screenshot actions (not the automatic post-action screenshots), and `propose_plan` now fetch bytes over the agent connection, store them in `chat_files`, link them to the chat, and carry attachment metadata in tool responses so `buildAssistantPartsForPersist` can materialize ordinary `type:"file"` assistant parts that the chat file APIs serve.
The same storage helpers are reused for other artifact-producing paths. `wait_agent` recordings and thumbnails are stored as chat files and linked back to the parent chat, with best-effort relinking so parent chats retain those artifacts without leaving orphaned rows when chat-file caps reject links. `storeChatAttachment` wraps insert + link in one transaction, files are capped at 10 MB each and 20 per chat, and serving defaults to `Content-Disposition: attachment` with an explicit inline-safe allowlist.
This PR also consolidates chat-file media policy in `coderd/chatfiles`. Uploads and tool-generated attachments share byte-based MIME detection, SVG blocking, inline-safety rules, and compatible `text/plain` refinement for JSON, CSV, and Markdown. Prompt construction still only inlines synthetic pasted text for model consumption; assistant-created attachments are persisted for the user and intentionally not replayed into later LLM turns.

The `DateRangePicker` accepts a `now` prop that stories and tests use to
pin preset ranges and future-date disabling to a deterministic clock,
but it never forwarded that value to the underlying `Calendar`.
`react-day-picker` then computed its own `today` from wall-clock time,
which drives both the "today" highlight modifier and the initial visible
month — causing stories like `TemplateInsightsControls:Day` to _flake_
as real time advanced.
Thread `currentTime` into `react-day-picker`'s `today` prop. When `now`
is omitted (production usage), `currentTime` falls back to `new Date()`,
which matches `react-day-picker`'s existing default, so there is no
runtime behavior change.

Fixes three classes of edit_files bugs and adds structured per-file
diff output for tool callers:
- New IncludeDiff flag on FileEditRequest; when set, the agent
returns FileEditResponse.Files[]{Path, Diff} with unified diffs
computed via go-udiff v0.4.1 Lines + ToUnified (not Unified,
which calls log.Fatalf on internal error).
- Fuzzy match comparators split each line into leading whitespace,
body, trailing whitespace, and ending. The splice substitutes at
each position: on agreement between search and replace the file's
bytes win; on disagreement the replacement's bytes are spliced
verbatim. Carve-outs for empty-body lines, multi-line EOF splices,
and level-aware indent translation for inserted lines.
- Indent-unit detection (GCD for spaces, tab-priority) lets a 4sp
LLM search insert correctly into tab or 2sp files. Falls back to
the previous cLead-inheritance path when units can't be detected
cleanly.
- Empty search is rejected with "search string must not be empty".
- Duplicate file paths in one request are rejected; symlink aliases
resolved via api.resolvePath before the dedup check.
- Frontend EditFilesRenderer consumes the structured files array by
explicit path (no label munging) with per-file synthetic fallback
for older agents or mismatched paths. On error, no diff is
rendered so the synthetic fallback doesn't misrepresent a
rejected edit as applied.
Breaking change: AgentConn.EditFiles changes from (ctx, req) error
to (ctx, req) (FileEditResponse, error) in codersdk/workspacesdk.
Source-breaking for external Go consumers; no compat shim per plan
owner.
Out of scope (tracked in CODAGT-214): level-aware indent for
middle-substituted splice lines. Locked in
TestEditFiles_FuzzyIndent_InsertionLevelAware's Lock_* cases plus
TestEditFiles_ReplaceAll_FuzzyIndentGap.
The shadcn-compatible CSS aliases (`--background`, `--foreground`,
`--muted`,
`--muted-foreground`, `--primary`, `--primary-foreground`) were added as
part
of the Coder agents work with hardcoded HSL values that duplicated
existing
semantic design tokens. These non-standard color classes (`bg-muted`,
`text-muted-foreground`, `text-foreground`) had started spreading
through
components like Table, MultiUserSelect, and WorkspacesTable.
This PR makes two changes:
1. **CSS aliases now derive from canonical tokens via `var()`
references**
instead of duplicating HSL values. The aliases remain for `streamdown`
and other external consumers, but `--background` now resolves to
`--surface-primary` (`#FFFFFF` in light, was `#FAFAFA`), and the rest
map to their semantic equivalents (`--content-primary`,
`--surface-secondary`, `--content-secondary`, `--content-link`).
2. **Component classes replaced with semantic equivalents:**
- `bg-muted` → `bg-surface-secondary`
- `text-muted-foreground` → `text-content-secondary`
- `text-foreground` → `text-content-primary`
- `text-amber-400` → `text-content-warning`
- `hsl(var(--background))` → `hsl(var(--surface-primary))`
- `hsl(var(--muted-foreground))` → `hsl(var(--content-secondary))`

GitHub rotates refresh tokens on use, invalidating the old token
immediately. If post-refresh validation fails (e.g. rate-limited
403 from /user), the new token was silently discarded because the
DB save only happened after successful validation. The next refresh
attempt would use the stale refresh token, fail permanently, and
destroy the token.
Move the UpdateExternalAuthLink call to immediately after
TokenSource.Token() succeeds. The post-validation save block is
removed (dead code after the early save). The DB write uses a
detached context (context.WithoutCancel) so a canceled request
cannot prevent persistence of the already-consumed refresh token.

- Log file write errors without blocking workspace startup
After password login, `navigate('/')` performed a client-side SPA
navigation, leaving the pre-authentication `<meta>` tags (including
`userAppearance`) empty in the DOM. The `ThemeProvider` read empty
metadata and fell through to `DEFAULT_THEME` until the API query
resolved, causing a visible flash of the wrong theme. A page refresh
fixed it because the server re-rendered HTML with the session cookie
present.
Replace `navigate('/')` with `window.location.href` so the server
re-renders HTML with all metadata tags populated (`userAppearance`,
`user`, `permissions`, etc.) via the new session cookie. This matches
the pattern already used for API route redirects on the same page. Also
uses `redirectTo` instead of hardcoded "/" so the redirect query
parameter is respected for password login.

Introduce Explore mode, a read-only subagent modality for delegated
discovery and code investigation.
## What
Adds a `spawn_explore_agent` tool that creates child chats restricted to
read-only operations. An admin can optionally configure a
deployment-wide
model override so Explore subagents use a model optimized for large
context
or reasoning without changing the root chat's model.
### Backend
- New `ChatModeExplore` enum value (migration 000471).
- `spawn_explore_agent` tool definition with read-only allowlist:
`read_file`, `execute`, `process_output`, `read_skill`,
`read_skill_file`.
Write tools, file editors, and nested subagent spawning are blocked.
- Deployment config storage for the Explore model override
(`agents_chat_explore_model_override` in `site_configs`).
- Model resolution hierarchy: configured override, then current turn
model,
then global default. Silent fallback with warning log when the override
becomes unavailable.
- RBAC: `AsChatd` for daemon reads, `ActionRead` and `ActionUpdate` on
`ResourceDeploymentConfig` for admin API calls.
- Plan mode root chats can use `spawn_explore_agent` for read-only
research,
matching the planning prompt guidance.
- The Explore override config API now reports malformed saved overrides
as
"treated as unset" so admins can clear them explicitly.
### Frontend
- `ExploreModelOverrideSettings` component in admin agent behavior
settings.
Uses `ModelSelector`, handles unavailable model warnings, and supports
explicit Save and Clear actions.
- Malformed saved overrides show a warning and require an explicit Save
to
clear, instead of Clear auto-submitting behind the scenes.
### Tests
- Integration: `TestExploreSubagentIsReadOnly` (full spawn flow, tool
verification, prompt overlay, DB state).
- Unit: tool allowlist tests for explore, plan, and default modes.
- Internal: model override resolution with valid, invalid UUID,
disabled, and
unconfigured override scenarios.
- RBAC: `dbauthz_test.go` for `GetChatExploreModelOverride` and
`UpsertChatExploreModelOverride`.
- API: admin set and clear, malformed stored override reporting,
disabled
model rejection, non-admin denial.
Add a new template to dev.coder.com for developing the coder/vscode-coder
VS Code extension.
The Docker image is based on node:24-slim (pinned by digest) with git, gh
CLI, dbus, and sudo. Electron system libraries are installed at workspace
startup via playwright install-deps so they stay in sync with the project's
Electron version without Dockerfile changes.
The template includes IDE selection (VS Code Desktop, code-server, Cursor,
etc.), filebrowser, dotfiles, and Claude Code for AI tasks.

Adds `coder exp agents`, an interactive terminal UI for managing Coder
AI agent chats. Built with bubbletea/lipgloss/glamour, the TUI provides
parity with the web dashboard for chat management, model selection, and
real-time tool execution visibility.
## What it does
- **Chat list view**: tree-based navigation with nested subagent
expansion, search filtering, windowed scrolling, and pagination.
- **Active chat view**: viewport-based transcript with markdown
rendering, WebSocket streaming, and a text input composer for sending
messages.
- **Model picker overlay**: cached model catalog with fuzzy selection.
- **Diff drawer overlay**: git changes inspection with unified diff
rendering.
- **Tool call rendering**: humanized argument summaries, consecutive
duplicate collapsing, and status indicators.
## Key implementation details
- Session lifecycle uses a monotonic `chatGeneration` counter so async
responses from stale sessions are dropped on chat switch.
- Draft mode guards prevent duplicate chat creation on double-Enter.
- Error and loading states render inline without collapsing the TUI
chrome.
- Glamour renderer access is mutex-protected (not thread-safe).
- Intentional WebSocket close is distinguished from dropped connections
to prevent spurious reconnects.
## Testing
~220 unit tests covering rendering, state transitions, keyboard
dispatch, and edge cases. 4-scenario PTY-based E2E suite covers boot,
navigation, search, and direct chat open.
14 new files, ~7,400 lines added.

## Summary
- add an enabled chat model config lookup by ID for internal callers
- keep `spawn_agent` unchanged while threading an internal model
override through child subagent chat creation
- extend chatd coverage for inherited bindings, plan mode, and internal
override behavior
## Validation
- `go test ./coderd/x/chatd ./coderd/database/dbauthz`
- `make lint`
Two `InsertChatParams` blocks in `startworkspace_test.go` were missing
the `ClientType` field. Since the `chat_client_type` enum column is `NOT
NULL`, Postgres rejects the Go zero value (`""`), causing
`TestStartWorkspace` subtests `StoppedWorkspaceReportsAutoUpdate` and
`ManualUpdateRequired` to fail with:
```
pq: invalid input value for enum chat_client_type: ""
```
Closes https://github.com/coder/internal/issues/1471
## Problem
When a template has `require_active_version` enabled and the chat agent
tries to start a workspace that is stopped on an older template version,
the agent gets stuck in an infinite loop: `start_workspace` fails with a
403 (the old version is not the active version and the user lacks
`ActionUpdate` on the template), then `create_workspace` sees the
existing stopped workspace and tells the agent to use `start_workspace`,
repeat forever.
The root cause is that `chatStartWorkspace()` passes the start build
request through without setting `TemplateVersionID`, so `wsbuilder`
defaults to the previous build's template version — which RBAC rejects
when `RequireActiveVersion` is true.
## Fix
In `chatStartWorkspace()` (`coderd/exp_chats.go`), when the template's
access control has `RequireActiveVersion` enabled, explicitly set
`req.TemplateVersionID` to `template.ActiveVersionID` before calling
`postWorkspaceBuildsInternal()`. This mirrors how the autobuild executor
handles the same scenario (`coderd/autobuild/lifecycle_executor.go`).
If the new active version introduces required parameters that cannot be
resolved automatically (no defaults, no previous values), the build
fails at parameter validation before a provisioner job is created. In
that case, a clear error message tells the user to update and start the
workspace from the UI instead of surfacing a raw internal error.
On successful auto-update, the tool response includes
`updated_to_active_version`, `update_reason`, and a human-readable
`message` so the model can explain to the user what happened.

/>
### Changes
- **`coderd/exp_chats.go`**: `chatStartWorkspace()` loads the template,
checks `RequireActiveVersion` via `AccessControlStore`, and pins the
build to the active version when required. New
`isChatStartWorkspaceManualUpdateRequiredError()` classifies parameter
validation failures from both the dynamic parameters path
(`DiagnosticError`) and the classic path (`ErrParameterValidation`
sentinel).
- **`coderd/wsbuilder/wsbuilder.go`**: New `ErrParameterValidation`
sentinel error, wrapped into the classic parameter validation
`BuildError` so callers can use `errors.Is` instead of string matching.
- **`coderd/x/chatd/chattool/startworkspace.go`**:
`waitForAgentAndRespond` now returns `map[string]any` instead of
`fantasy.ToolResponse`, letting the caller annotate the result (e.g.
auto-update metadata) before converting. Error handling for `StartFn`
checks for `httperror.Responder` errors to surface clean messages for
the manual-update case.
- **`coderd/x/chatd/chattool/startworkspace_test.go`**: Two new tests —
`StoppedWorkspaceReportsAutoUpdate` (verifies auto-update fields in
response) and `ManualUpdateRequired` (verifies clean error message
without internal wrapping).
### Follow-up
The manual-update error message could include a direct link to the
workspace settings page, but the chattool layer does not currently have
access to the deployment's access URL. Plumbing it through is
straightforward but out of scope for this fix.
Closes CODAGT-192
Replace the old `InTx` ruleguard rule in `scripts/rules.go` with a
custom in-tree `go/analysis` analyzer under `scripts/intxcheck/`. The
new analyzer catches the same direct and pass-through misuse classes as
before, plus two new classes the pattern-matcher couldn't reach:
- **Indirect same-package helper misuse** — flags `p.someHelper(ctx)`
inside `InTx` when the helper body uses the outer store (the PR #24369
bug class).
- **Nested dangerous closures** — descends into `go func() { ... }()`,
`defer func() { ... }()`, and immediately-invoked function literals.
The analyzer uses semantic `types.Object` identity instead of raw
expression string comparison, which avoids false positives from
closure-local shadowing and catches simple aliases like `outer := s.db`
and `alias := s`.
This PR also fixes three real outer-store-inside-transaction bugs the
new analyzer surfaced:
- `coderd/wsbuilder/wsbuilder.go`: `FindMatchingPresetID` and
`getWorkspaceTask` now use the inner transaction store instead of
`b.store`.
- `enterprise/dbcrypt/dbcrypt.go`: `ensureEncrypted` now calls
`s.InsertDBCryptKey` (the tx-wrapped store) instead of
`db.InsertDBCryptKey`. The `dbCrypt.InTx` method wraps the raw tx in a
new `*dbCrypt`, so `s.InsertDBCryptKey` still dispatches through the
encryption layer.
Two call sites need `// intxcheck:ignore` suppressions. Both are one-off
patterns that only look like misuse because the analyzer doesn't track
assignments — proving them safe would require full dataflow analysis,
which is well beyond what a targeted lint like this should attempt:
- `coderd/database/dbfake/dbfake.go` — `b.db` is reassigned to `tx` on
the preceding line, so `b.doInTX()` actually uses the transaction. The
analyzer sees the original `b.db` identity and flags it.
- `coderd/database/db_test.go` — test intentionally passes the outer
store to `require.Equal` to assert that nested `InTx` returns the same

Suppressions use `// intxcheck:ignore` instead of `//nolint:intxcheck`
because `intxcheck` runs as a standalone `go/analysis` tool outside
golangci-lint. golangci-lint's `nolintlint` checker flags `//nolint`
directives for linters it doesn't control, so we use a custom comment
prefix to avoid that conflict.
