The agent row tooltip showed "Error starting the agent" / "Something
went wrong during the agent startup" with a red border when a startup
script fails. This is misleading — the agent is started and functional,
only the startup script exited with a non-zero code.
Extracts shared message constants (`agentLifecycleMessages`,
`agentStatusMessages`) from `health.ts` so both the workspace-level
health classification and the per-agent-row tooltips reference the same
single source of truth. No more duplicated wording that can drift.
Changes:
- **`health.ts`**: Exports `agentLifecycleMessages` and
`agentStatusMessages` maps; `getAgentHealthIssue` now references them
instead of inline strings.
- **`AgentStatus.tsx`**: All lifecycle/status tooltip components
(`StartErrorLifecycle`, `StartTimeoutLifecycle`,
`ShutdownTimeoutLifecycle`, `ShutdownErrorLifecycle`, `TimeoutStatus`)
now import and render from the shared message constants.
`StartErrorLifecycle` icon changed from red (`errorWarning`) to orange
(`timeoutWarning`).
- **`AgentRow.tsx`**: `start_error` border changed from
`border-border-destructive` (red) to `border-border-warning` (orange).

- Add `chat-access` built-in role granting chat CRUD at User scope
- Exclude `ResourceChat` from member, org member, and org service
account `allPermsExcept` calls
- Allow system, owner, and user-admin to assign the new role
- Migration auto-assigns role to users who have ever created a chat
- Update RBAC test matrix: `memberMe` denied, `chatAccessUser` allowed
**Breaking change**: Members without `chat-access` lose chat creation
ability. Migration covers existing chat creators. Members who have never
created a chat do not get this role automatically applied.

While running scaletests I noticed the archived filter button on the
agents sidebar would disappear when the current filter had zero results.
This made it impossible to switch between active and archived views once
one side was empty.
The filter dropdown was only rendered inside the Pinned or first
time-group section header. When `visibleRootIDs` was empty, neither
header existed, so the filter had nowhere to attach.
This keeps the original dropdown placement on section headers when chats
exist. When the list is empty, the empty-state box itself now provides a
"View archived →" or "← Back to active" link so users can always switch
filters without needing the dropdown.

WebKit internally adjusts scrollTop during layout when content
above the viewport changes height, even with overflow-anchor:none.
These phantom adjustments fire scroll events where isNearBottom
returns false. The scroll handler was setting autoScrollRef =
nearBottom on every such event, permanently killing follow mode.
The scroll handler now only enables follow mode, never disables
it. When follow mode is active, the user is not wheel/touch
scrolling, and isNearBottom is false, this indicates a
browser-initiated scroll adjustment. Re-pin immediately and
set the restore guard so the pin's own scroll event is suppressed.
Disabling follow mode is exclusive to user-interaction handlers
(wheel, touch, scrollbar pointerdown) via handleUserInterrupt.
Guard-clear callbacks also check isNearBottom before dropping
the restoration flag, re-pinning if content grew between the
pin and the clear.
Updates the descriptive text in the proxy selection dropdown menu to be
clearer and more concise.

Adds a nullable JSONB column `last_injected_context` to the `chats`
table that stores the most recently persisted injected context parts
(AGENTS.md context-file and skill message parts). The column is updated
only when `persistInstructionFiles()` runs — on first workspace attach
or when the agent changes — so there are no redundant writes on
subsequent turns.
Internal fields (`ContextFileContent`, `ContextFileOS`,
`ContextFileDirectory`, `SkillDir`) are stripped at write time so the
column only holds small metadata. No stripping needed on the read path.
<details>
<summary>Implementation notes</summary>
- New migration `000456` adds nullable `last_injected_context JSONB`
column.
- New SQL query `UpdateChatLastInjectedContext` writes the column
without touching `updated_at`.
- `persistInstructionFiles()` strips internal fields from parts via
`StripInternal()` before persisting.
- Sentinel path (no AGENTS.md) persists skill-only parts when skills
exist.
- `codersdk.Chat` exposes `LastInjectedContext []ChatMessagePart`
(omitempty).
- `db2sdk.Chat()` passes through the already-clean data.
</details>
Two ResizeObserver effects (content and container) each had their own
local restoreGuardRafId but both wrote to the shared
isRestoringScrollRef. Either observer's guard-clear RAF could fire
while the other's pin chain was in-flight, leaving isRestoringScrollRef
prematurely false.
scrollTranscriptToBottom also set isRestoringScrollRef without
cancelling any pending guard-clear, so a stale clear could drop
the flag mid-smooth-scroll animation.
Promote restoreGuardRafId to a single shared ref so all write
paths coordinate through one cancellation point.
## Problem
The `/agents` page frequently shows "Response startup is taking longer
than expected" even while the agent is actively working and messages are
appearing in the transcript.
## Root Cause
There's an inconsistency between `isActiveChatStatus` and
`shouldApplyMessagePart` during `"pending"` status (the state between
agent tool-call turns):
| Component | Treats `"pending"` as... |
|---|---|
| `isActiveChatStatus` | **active** — includes both `"running"` and
`"pending"` |
| `shouldApplyMessagePart` | **inactive** — drops all `message_part`
events during `"pending"` |
| Status handler | clears `streamState` to `null` on `"pending"` |
This creates a dead state during multi-turn tool-call cycles:
1. Agent finishes a turn → status = `"pending"` → `streamState` cleared
to `null`
2. `selectIsAwaitingFirstStreamChunk` returns `true` (status is
"active", stream is null, latest message isn't assistant)
3. Phase = `"starting"` → 15s timer starts
4. Stream parts from the server are **silently dropped**
(`shouldApplyMessagePart()` returns `false` for `"pending"`)
5. `streamState` stays `null` — phase is stuck at `"starting"`
6. Meanwhile, durable messages (tool calls, tool results) appear
normally in the transcript
7. After 15s → "Response startup is taking longer than expected" fires
## Fix
Narrow `selectIsAwaitingFirstStreamChunk` to only check `chatStatus ===
"running"` instead of `isActiveChatStatus(chatStatus)`. `"running"` is
the only status where the transport actually accepts stream parts, so
it's the only status where we should be showing the "starting"
indicator.
`isActiveChatStatus` is left unchanged since its other caller
(`shouldSurfaceReconnectState`) correctly needs to include `"pending"`.
scheduleBottomPin() cancelled any in-flight pin and restarted the
double-RAF chain on every ResizeObserver notification. When content
height changes on consecutive frames (e.g. during streaming where
SmoothText reveals characters each frame and markdown re-rendering
occasionally changes block height), the inner RAF that actually sets
scrollTop is perpetually cancelled before it fires. The scroll falls
behind the growing content.
Two fixes:
1. Make scheduleBottomPin() idempotent: if a pin is already in-flight,
skip. The inner RAF reads scrollHeight at execution time so it
always targets the latest bottom. User-interrupt paths (wheel,
touch) still cancel via cancelPendingPins().
2. Add overscroll-behavior:contain to the scroll container. Prevents
elastic overscroll from generating extra scroll events that could
flip autoScrollRef to false.
Replace the raw JSON dump for process_signal with the standard
ToolCollapsible + ToolIcon + ToolLabel pipeline, matching process_list
and other generic tools. A thin ProcessSignalRenderer promotes soft
failures (success=false, isError=false) so the generic renderer shows
the error indicator. ToolLabel distinguishes running, success, and
failure states. TerminalIcon used for consistency with other process
tools.
When a process is killed via process_signal, the execute and
process_output blocks show a red OctagonX icon with signal details
on hover. The killedBySignal field is set on MergedTool during the
existing cross-message parsing pass, no new abstractions.
Stories for process_signal (10) and killed indicators (8). Unit
tests for the cross-tool annotation logic (3). Humanized labels
and TerminalIcon for process_list.
## Problem
When the workspaces table transitions between states (loading →
populated, or populated → empty search results), the table column
headers visibly jump. This happens because the Actions column's width is
content-driven: when workspace rows are present, the action buttons give
it intrinsic width, shrinking the Name/Template/Status columns. When the
body is empty or loading, the Actions column collapses to zero, and the
other columns expand to fill the space.
## Solution
Hide the header content during loading and empty states using
`visibility: hidden` (Tailwind's `invisible` class), which preserves the
row's layout height but hides the text. This prevents the visual jump
since headers aren't visible during the states where column widths
differ.
- **Loading**: first column shows a skeleton bar matching the body
skeleton aesthetic; other columns are invisible
- **Empty search results**: all header content is invisible
- **Populated**: headers display normally

## Summary
Skills are now discovered once on the first turn (or when the workspace
agent changes) and persisted as `skill` message parts alongside
`context-file` parts. On subsequent turns, the skill index is
reconstructed from persisted parts instead of re-dialing the workspace
agent.
This makes skills consistent with the AGENTS.md pattern and is
groundwork for a future `/context` endpoint that surfaces loaded
workspace context to the frontend.
## Changes
- Add `skill` `ChatMessagePartType` with `SkillName` and
`SkillDescription` fields
- Extend `persistInstructionFiles` to also discover and persist skills
as parts
- Add `skillsFromParts()` to reconstruct skill index from persisted
parts on subsequent turns
- Update `runChat()` to use `skillsFromParts` instead of re-dialing
workspace for skills
- Frontend: handle new `skill` part type (skip rendering, hide
metadata-only messages)
## Before / After
| | AGENTS.md | Skills |
|---|---|---|
| **Before** | Persist as `context-file` parts, reconstruct from parts |
In-memory `skillsCache` only, re-dial workspace on cache miss |
| **After** | Persist as `context-file` parts, reconstruct from parts |
Persist as `skill` parts, reconstruct from parts |
The in-memory `skillsCache` remains for `read_skill`/`read_skill_file`
tool calls that need full skill bodies on demand.
<details><summary>Design context</summary>
This is the first step toward a unified workspace context
representation. Currently:
- Context files are persisted as message parts (works)
- Skills were only in-memory (inconsistent)
- Workspace MCP servers are cached in-memory (future work)
Persisting skills as parts means a future `/context` endpoint can query
both context files and skills from the same message parts in the DB,
without depending on ephemeral server-side caches.

Previously, generating a new agent title used a page-global pending
state, so one in-flight regeneration disabled the action for every chat
in the Agents UI.
This change tracks regenerations by chat ID, updates the Agents page
contracts to use `regeneratingTitleChatIds`, and adds sidebar story
coverage that proves only the active chat is disabled.
## Problem
The context-usage indicator ring in the agents chat uses a Radix UI
`Tooltip`, which only opens on hover. On mobile/touch devices there is
no hover event, so tapping the indicator does nothing.
## Fix
On mobile viewports (`< 640 px`, matching the existing
`isMobileViewport()` helper), render a `Popover` instead of a `Tooltip`
so that tapping the ring toggles the context-usage info. Desktop
behavior (hover tooltip) is unchanged.
- Extract the trigger button and content into shared variables to avoid
duplication
- Conditionally render `Popover` (mobile) or `Tooltip` (desktop) based
on viewport width
- Both `Popover` and `PopoverContent` were already imported in the file

This pull-request implements a `<ClientFilter />` to our `Request Logs`
page for AI Bridge. This will allow the user to select a client which
they wish to filter against. Technically the backend is able to actually
filter against multiple clients at once however the frontend doesn't
currently have a nice way of supporting this (future improvement).

Split out from #23000.
## Problem
`openAppInNewWindow()` opens workspace apps in a slim popup without
`noopener`, leaving `window.opener` intact. Since workspace apps can
proxy arbitrary user-hosted content under the dashboard origin, this
exposes the Coder dashboard to tabnabbing and same-origin DOM access.
We cannot simply pass `"noopener"` to `window.open()` because the WHATWG
spec mandates that `window.open()` returns `null` when `"noopener"` is
present — indistinguishable from a blocked popup — which would break the
popup-blocked error toast.
## Solution
Use a two-step approach in `openAppInNewWindow()`:
1. Open `about:blank` first (without `noopener`) so we can detect popup
blockers via the `null` return
2. If the popup succeeded, sever the opener reference with `popup.opener
= null`
3. Navigate the popup to the target URL via `popup.location.href`
This preserves popup-block detection while eliminating the security
exposure.
## Tests
A vitest case in `AppLink.test.tsx` asserts that `open_in="slim-window"`
anchors do not carry `target` or `rel` attributes (since slim-window
opening is handled programmatically via `onClick` / `window.open()`, not
anchor attributes).

Removes the `font-semibold` class applied to unread chat titles in the
`/agents` sidebar. The unread indicator dot already provides sufficient
visual distinction for unread chats.
## Summary
Adds read/unread tracking for chats so users can see which agent
conversations have new assistant messages they haven't viewed.
## Backend Changes
- Adds `last_read_message_id` column to the `chats` table (migration
000439).
- Computes `has_unread` as a virtual column in `GetChatsByOwnerID` using
an `EXISTS` subquery checking for assistant messages beyond the read
cursor.
- Exposes `has_unread` on the `codersdk.Chat` struct and auto-generated
TypeScript types.
- Updates `last_read_message_id` on stream connect/disconnect in
`streamChat`, avoiding per-message API calls during active streaming.
- Uses `context.WithoutCancel` for the deferred disconnect write so the
DB update succeeds even after the client disconnects.
## Frontend Changes
- Bold title (`font-semibold`) for unread chats in the sidebar.
- Small blue dot indicator next to the relative timestamp.
- Suppresses unread indicator for the currently active chat via
`isActive` from NavLink.
## Design Decisions
- Only `assistant` messages count as unread — the user's own messages
don't trigger the indicator.
- No foreign key on `last_read_message_id` since messages can be deleted
(via rollback/truncation) and the column is just a high-water mark.
- Zero API calls during streaming: exactly 2 DB writes per stream
session (connect + disconnect).
- Unread state refreshes on chat list load and window focus. The
`watchChats` WebSocket optimistically marks non-active chats as unread
on `status_change` events, but does not carry a server-computed
`has_unread` field. Navigating to a chat optimistically clears its
unread indicator in the cache.
`onChatReady` now waits for the store to have all fetched messages (not
just query success), so the DOM has content when the parent frame acts
on the signal. Removed the `scroll-to-bottom` round-trip from
`onChatReady`, the embed page no longer needs the parent to echo a
scroll command back.
Also moved `autoScrollRef` check before the `widthChanged` guard in
`ScrollAnchoredContainer`'s ResizeObserver. The width guard is only
relevant for scroll compensation (user scrolled up); it should never
prevent pinning to bottom when auto-scroll is active. Also tightened the
store sync guard to `storeMessageCount < fetchedMessageCount`.
Addresses chat page rendering performance. Profiling with React Profiler
showed `AgentChat` actual render times of 20–31ms (exceeding the
16ms/60fps
budget), with `StickyUserMessage` as the #1 component bottleneck at
35.7%
of self time.
## Changes
**Hoist `createComponents` to module scope** (`response.tsx`):
Previously every `<Response>` instance called `createComponents()` per
render, creating a fresh components map that forced Streamdown to
discard
its cached render tree. Now both light/dark variants are precomputed
once
at module scope.
**Wrap `StickyUserMessage` in `memo()`** (`ConversationTimeline.tsx`):
Profile-confirmed #1 bottleneck. Each instance carries
IntersectionObserver
+ ResizeObserver + scroll handlers; skipping re-render avoids all that
setup.
**Wrap `ConversationTimeline` in `memo()`**
(`ConversationTimeline.tsx`):
Prevents cascade re-renders from the parent when props haven't changed.
**Remove duplicate `buildSubagentTitles`** (`ConversationTimeline.tsx` →
`AgentDetailContent.tsx`): Was computed in both `AgentDetailTimeline`
and
`ConversationTimeline`. Now computed once and passed as a prop.

### Profiler Metrics
| Metric | Value |
|--------|-------|
| INP (Interaction to Next Paint) | 82ms |
| Processing duration (event handlers) | 52ms |
| AgentChat actual render | 20–31ms (budget: 16ms) |
| AgentChat base render (no memo) | ~100ms |
### Top Bottleneck Components (self-time %)
| Component | Self Time | % |

| Presence (radix-ui) | 2.0ms | 6.5% |
| AgentChatInput | 1.4ms | 4.5% |
### Decision log
- Chose module-scope precomputation over `useMemo` for
`createComponents`
because there are only two possible theme variants and they're static.
- Did not add virtualization — sticky user messages + scroll anchoring
make it complex. The memoization fixes should be measured first.
- Did not wrap `BlockList` in `memo()` — the React Compiler (enabled for
`pages/AgentsPage/`) already auto-memoizes JSX elements inside it.
- Phase 2 (verify React Compiler effectiveness on
`parseMessagesWithMergedTools`)
and Phase 3 (radix-ui Tooltip lazy-mounting) deferred to follow-up PRs.

Add a per-MCP-server `model_intent` toggle that wraps tool schemas with
a
`model_intent` field, requiring the LLM to provide a human-readable
description of each tool call's purpose. The intent string is shown as a
status label in the UI instead of opaque tool names, and is
transparently
stripped before the call reaches the remote MCP server.
Built-in tools have rich specialized renderers (terminal blocks, file
diffs,
etc.) and don't need this. MCP tools hit `GenericToolRenderer` which
only
shows raw tool names and JSON — that's where model_intent adds value.
The model learns what to provide via the JSON Schema `description` on
the
`model_intent` property itself — no system prompt changes needed.
<details>
<summary>Implementation details</summary>
### Architecture
Inspired by the `withModelIntent()` pattern from `coder/blink`, adapted
for
Go + React. The wrapping is entirely in the `mcpclient` layer — tool
implementations never see `model_intent`.
**Schema wrapping** (`mcpToolWrapper.Info()`): When enabled, wraps the
original tool parameters under a `properties` key and adds a
`model_intent`
string field with a rich description that teaches the model inline.
**Input unwrapping** (`mcpToolWrapper.Run()`): Strips `model_intent` and
unwraps `properties` before forwarding to the remote MCP server. Handles
three input shapes models may produce:
1. `{ model_intent, properties: {...} }` — correct format
2. `{ model_intent, key: val, ... }` — flat, no wrapper
3. Malformed — falls through gracefully
**Frontend extraction**: `streamState.ts` extracts `model_intent` from
incrementally parsed streaming JSON. `messageParsing.ts` extracts it
from
persisted tool call args.
**UI rendering**: `GenericToolRenderer` shows the capitalized intent
string
as the primary label when available, falling back to the raw tool name.
### Changes
- Database: `model_intent` boolean column on `mcp_server_configs`
- SDK: `ModelIntent` field on config/create/update types
- API: pass-through in create/update handlers + converter
- mcpclient: schema wrapping in `Info()`, input unwrapping in `Run()`
- Frontend: extraction from streaming + persisted args
- UI: intent label in `GenericToolRenderer`, toggle in admin panel
- Tests: 6 new tests (schema wrapping, unwrapping, passthrough,
fallback)
### Decision log
- **Option lives on MCPServerConfig, not model config**: Built-in tools
already have rich renderers; only MCP tools benefit from model_intent.
- **No system prompt changes**: The JSON Schema `description` on the
`model_intent` property teaches the model inline.
- **Pointer bool on update request**: Follows existing pattern (`*bool`)
so PATCH requests don't reset the value when omitted.
</details>
## Summary
Fixes two issues with pinned chat drag-to-reorder in the agents sidebar:
1. **Missing optimistic reorder**: After dragging a pinned chat to a new
position, the sidebar flashed back to the old order while waiting for
the server response, then snapped to the new order. Now the react-query
cache is updated optimistically in `onMutate` so the reorder is visually
instant.
2. **Post-drag navigation on upward drag**: Dragging a pinned chat
**upward** caused unintended navigation to that chat on drop. The
browser synthesizes a click from the final `pointerup`, and the previous
suppression listener was attached too low in the DOM tree to reliably
intercept it after items reorder.
## Changes
### Optimistic cache reorder (`site/src/api/queries/chats.ts`)
`reorderPinnedChat.onMutate` now extracts all pinned chats from the
cache, reorders them to match the new position, and writes the updated
`pin_order` values back via `updateInfiniteChatsCache`. The server
response still reconciles on `onSettled`.
### Document-level click suppression (`AgentsSidebar.tsx`)
- Moved click suppression from the pinned container div to
`document.addEventListener('click', handler, true)`. This fires before
any element-level handlers regardless of DOM reordering during drag.
Scoped via `pinnedContainerRef.contains(target)` so it only affects
pinned rows.
- Replaced `recentDragRef` (boolean cleared by `setTimeout(100ms)`) with
`lastDragEndedAtRef` (`performance.now()` timestamp checked against a
300ms window). This eliminates the race where the timeout fires before
the synthetic click arrives.

## Summary
Adds a "Generate new title" action that lets users manually regenerate a
chat's title using richer conversation context than the automatic
first-message title path.
## Changes
### Backend
- **New endpoint:** `POST
/api/experimental/chats/{chatID}/title/regenerate` returns the updated
Chat with a regenerated title
- **Manual title algorithm:** Extracts useful user/assistant text turns
→ selects first user turn + last 3 turns → builds context with gap
markers → renders prompt with anti-recency guidance → calls lightweight
model → normalizes output
- **Helpers:** `extractManualTitleTurns`,
`selectManualTitleTurnIndexes`, `buildManualTitleContext`,
`renderManualTitlePrompt`, `generateManualTitle` — all private, with the
public `Server.RegenerateChatTitle` method
- **SDK:** `ExperimentalClient.RegenerateChatTitle(ctx, chatID) (Chat,
error)`
- Persists title via existing `UpdateChatByID` and broadcasts
`ChatEventKindTitleChange`
### Frontend
- API client method + React Query mutation with cache invalidation
- "Generate new title" menu item (with wand icon) in both TopBar and
Sidebar dropdown menus
- Loading/disabled state while regeneration is in-flight
- Error toast on failure
- Stories updated for both menus
### Tests
- `quickgen_test.go`: Table-driven tests for all 4 helper functions
(turn extraction, index selection, context building, prompt rendering)
- `exp_chats_test.go`: Handler tests (ChatNotFound,
NotFoundForDifferentUser, NoDaemon)
## Design notes
- The existing auto-title path (`maybeGenerateChatTitle`, `titleInput`)
is completely unchanged
- Manual regeneration uses richer context (first user turn + last 3
turns + gap markers) vs the auto path's single first message
- Endpoint is experimental and marked with `@x-apidocgen {"skip": true}`
Converts the Agents page transcript from reverse-scroll
(\`flex-col-reverse\`) to normal top-to-bottom document flow with
explicit auto-scroll pinning.
The previous \`flex-col-reverse\` approach (from #23451) required
browser-specific workarounds for Chrome vs Firefox \`scrollTop\` sign
conventions, and compensation logic that could fight user scroll intent
during streaming. This replaces it with standard scroll math
(\`scrollHeight - scrollTop - clientHeight\`) while keeping the proven
\`ScrollAnchoredContainer\` observer machinery.
Changes:
- \`AgentDetailView.tsx\`: layout flip to \`flex-col\`, standard bottom
detection, explicit prepend restoration via \`pendingPrependRef\`
snapshot, sentinel moved inside content wrapper, initial mount bottom
pin, \`scrollToBottomRef\` imperative API for send/edit, user-interrupt
guard with \`isNearBottom\` check
- \`AgentDetailView.stories.tsx\`: all scroll stories updated for
normal-flow semantics, new \`ScrollAnchorPreservedOnOlderHistoryLoad\`
story with deterministic \`IntersectionObserver\` mock
- \`AgentsSkeletons.tsx\` + \`AgentDetailLoadingView\`: removed
\`flex-col-reverse\` so loading state matches the real transcript layout
- \`AgentDetail.tsx\`: replaced \`scrollTop = 0\` on send/edit with
imperative \`scrollToBottomRef\` call
Supersedes #23576 (which was reverted in #23638). Same behavioral goals
but keeps scroll logic local to \`ScrollAnchoredContainer\` rather than
extracting a separate hook.
