## Problem
The `/agents/settings/insights` page was broken because
`InsightsContent` was calling `/api/v2/chats/insights/pull-requests`,
but the backend route is registered under
`/api/experimental/chats/insights/pull-requests` (the entire `/chats`
route block lives under `r.Route("/api/experimental", ...)` in
`coderd.go`).
Every other chat endpoint in the frontend correctly uses
`/api/experimental/chats/...`, but this one was missed.
## Fix
- Added `getPRInsights` method to the API client (`api.ts`) pointing to
`/api/experimental/chats/insights/pull-requests`
- Added a `prInsights` react-query helper in `api/queries/chats.ts`
(matching the pattern of `chatCostUsers`, etc.)
- Updated `InsightsContent.tsx` to use the query helper instead of a raw
`fetch()` with the wrong URL
Processes started via the agent process API inherited the agent's
own working directory (/tmp/coder.xxx) when no WorkDir was
specified. SSH sessions already use a fallback chain: configured
agent directory > $HOME. This wires the same manifest directory
closure into the process manager so the priority is now:
explicit req.WorkDir > agent configured dir > $HOME
The resolved directory is recorded on the process struct so
ProcessInfo.WorkDir and pathStore notifications reflect where
the process actually ran.
Replaces the singular `InsertChatMessage` query with
`InsertChatMessages` that uses PostgreSQL's `unnest()` for batch
inserts. This reduces the number of database round-trips when inserting
multiple messages in a single transaction.
## Changes
- **SQL**: New `InsertChatMessages :many` query using `unnest()` arrays
following the existing codebase pattern (e.g.,
`InsertWorkspaceAgentStats`). Preserves the CTE that updates
`chats.last_model_config_id` using the last non-null model config from
the batch. Uses `NULLIF` for UUID columns to handle NULL foreign keys.
- **Go layers**: Updated `querier.go`, `dbauthz.go`,
`dbmetrics/querymetrics.go`, `dbmock/dbmock.go`, and `queries.sql.go` to
use the new batch signature (`[]ChatMessage` return type, array params).
- **chatd.go**: All call sites converted to batch inserts:
- **CreateChat**: System prompt + user message batched into one call
- **persistStep**: Assistant message + tool messages batched into one
call
- **persistSummary**: Hidden summary + assistant + tool messages batched
into one call
- Single-message sites use the same API with single-element arrays
- **Helper**: New `appendChatMessage` function simplifies building batch
params at each call site.
- **Tests**: All test files updated to use the new API.

Two migrations were merged with the same number 000444:
- `000444_usage_events_ai_seats` (#22689, merged first at 09:30) — keeps
000444
- `000444_chat_message_runtime_ms` (#23219, merged second at 10:57) —
renumbered to **000445**
This collision causes `golang-migrate` to fail at runtime since it reads
both files as the same version.
**Fix:** Rename `000444_chat_message_runtime_ms.{up,down}.sql` →
`000445_chat_message_runtime_ms.{up,down}.sql`.

## What
Adds a new admin-only **PR Insights** page for the `/agents` analytics
view — a dashboard for engineering leaders to understand code shipped by
AI agents.
### Backend
- `GET /api/v2/chats/insights/pull-requests` — admin-only endpoint
- 4 SQL queries in `chatinsights.sql` aggregating `chat_diff_statuses`
joined with chat cost data (via root chat tree rollup)
- Runs 5 parallel DB queries: current summary, previous summary (for
trends), time series, per-model breakdown, recent PRs
- SDK types auto-generate to TypeScript
### Frontend (`PRInsightsView`)
- **Stat cards**: PRs created, Merged, Merge rate, Lines shipped,
Cost/merged PR — with trend badges comparing to previous period
- **Activity chart**: Stacked area chart (created/merged/closed) using
git color tokens (`git-added-bright`, `git-merged-bright`,
`git-deleted-bright`)
- **Model performance table**: Per-model PR counts, inline merge rate
bars, diff stats, cost breakdown
- **Recent PRs table**: Status badges, review state icons, author info,
external links
- **Time range filter**: 7d/14d/30d/90d button group
- **4 Storybook stories**: Default, HighPerformance, LowVolume, NoPRs
### Data source
All PR data comes from the existing `chat_diff_statuses` table
(populated by the `gitsync.Worker` background job that polls GitHub
every 120s). No new data collection required.
### Screenshot
View in Storybook: `pages/AgentsPage/PRInsightsView`
## Summary
Adds a `runtime_ms` column to `chat_messages` that records the
wall-clock duration (in milliseconds) of each LLM step. This covers LLM
streaming, tool execution, and retries — the full time the agent is
"alive" for a step.
This is the foundation for billing by agent alive time. The column
follows the same pattern as `total_cost_micros`: stored per assistant
message, aggregatable with `SUM()` over time periods by user.
## Changes
- **Migration**: adds nullable `runtime_ms bigint` to `chat_messages`.
- **chatloop**: adds `Runtime time.Duration` field to `PersistedStep`,
measures `time.Since(stepStart)` at the beginning of each step (covering
stream + tool execution + retries).
- **chatd**: passes `step.Runtime.Milliseconds()` to the assistant
message `InsertChatMessage` call; all other message types (system, user,
tool) get `NULL`.
- **Tests**: adds `runtime > 0` assertion in chatloop tests.
## Billing query pattern
Once ready, aggregation mirrors the existing cost queries:
```sql
SELECT COALESCE(SUM(cm.runtime_ms), 0)::bigint AS total_runtime_ms
FROM chat_messages cm
JOIN chats c ON c.id = cm.chat_id
WHERE c.owner_id = @user_id
AND cm.created_at >= @start_time
AND cm.created_at < @end_time
AND cm.runtime_ms IS NOT NULL;
```
## Description
Implements the server-side merge logic for the `merge_strategy`
attribute added to `coder_env` in [terraform-provider-coder
v2.15.0](https://github.com/coder/terraform-provider-coder/pull/489).
This allows template authors to control how duplicate environment
variable names are combined across multiple `coder_env` resources.
Relates to https://github.com/coder/coder/issues/21885
## Supported strategies
| Strategy | Behavior |
|----------|----------|
| `replace` (default) | Last value wins — backward compatible |
| `append` | Joins values with `:` separator (e.g. PATH additions) |
| `prepend` | Prepends value with `:` separator |
| `error` | Fails the build if the variable is already defined |
## Example
```hcl
resource "coder_env" "path_tools" {
agent_id = coder_agent.dev.id
name = "PATH"
value = "/home/coder/tools/bin"
merge_strategy = "append"
}
```
## Changes
- **Proto**: Added `merge_strategy` field to `Env` message in
`provisioner.proto`
- **State reader**: Updated `agentEnvAttributes` struct and proto
construction in `resources.go`
- **Merge logic**: Added `mergeExtraEnvs()` function in
`provisionerdserver.go` with strategy-aware merging for both agent envs
and devcontainer subagent envs
- **Tests**: 15 unit tests covering all strategies, edge cases (empty
values, mixed strategies, multiple appends)
- **Dependency**: Bumped `terraform-provider-coder` v2.14.0 → v2.15.0
- **Fixtures**: Updated `duplicate-env-keys` test fixtures and golden
files
## Ordering
When multiple resources `append` or `prepend` to the same key, they are
processed in alphabetical order by Terraform resource address (per the
determinism fix in #22706).
When a chat is created via `chatd`, a system message is now inserted
informing the model whether the chat was created with or without a
workspace.
**With workspace:**
> This chat is attached to a workspace. You can use workspace tools like
execute, read_file, write_file, etc.
**Without workspace:**
> There is no workspace associated with this chat yet. Create one using
the create_workspace tool before using workspace tools like execute,
read_file, write_file, etc.
This is a model-only visibility system message (not shown to users) that
helps the model understand its available capabilities upfront —
particularly important for subagents spawned without a workspace, which
previously would attempt to use workspace tools and fail.
**Changes:**
- `coderd/chatd/chatd.go`: Added workspace awareness constants and
inserted the system message in `CreateChat` after the system prompt,
before the initial user message.
- `coderd/chatd/chatd_test.go`: Added
`TestCreateChatInsertsWorkspaceAwarenessMessage` with sub-tests for both
with-workspace and without-workspace cases.
## Summary
- add a hidden deployment config option for chat acquire batch size
(`CODER_CHAT_ACQUIRE_BATCH_SIZE` / `chat.acquireBatchSize`)
- thread the configured value into chatd startup while preserving the
existing default of `10`
- clamp the deployment value to the `int32` range before passing it into
chatd
- regenerate the API/docs/types/testdata artifacts for the new config
field
## Why
`chatd` currently acquires pending chats in batches of `10` via a
compile-time default. This change makes that batch size
operator-configurable from deployment config, so we can tune acquisition
behavior without another code change.
Both message parsers accepted untyped input and relied on scattered
asRecord/asString calls to extract fields at runtime. With the
discriminated ChatMessagePart union, both accept typed input directly
and narrow via switch (part.type).
parseMessageContent narrows from (content: unknown) to
(content: readonly ChatMessagePart[] | undefined), removing legacy
input shape handling the Go backend normalizes away.
applyMessagePartToStreamState narrows from Record<string, unknown>
to ChatMessagePart.
The SSE type guards had a & Record<string, unknown> intersection
that widened everything untyped downstream. Since the data comes
from our own API, the intersection was removed and all handlers in
ChatContext now use generated types directly.
Fixes tool_call_id and tool_name variant tags in codersdk/chats.go:
marked optional to match reality (Go guards against empty values,
omitempty omits them at the wire level).

Fixes AIGOV-141
The `coder support bundle` command previously required admin permissions
(`Read DeploymentConfig`) and would abort entirely for non-admin
`member` users with:
```
failed authorization check: cannot Read DeploymentValues
```
This change makes the command **degrade gracefully** instead of failing
outright.
<details>
<summary>
Changes
</summary>
### `support/support.go`
- **`Run()`**: The authorization check for `Read DeploymentValues` is
now a soft warning instead of a hard gate. Unauthenticated users (401)
still fail, but authenticated users with insufficient permissions
proceed with reduced data.
- **`DeploymentInfo()`**: `DeploymentConfig` and `DebugHealth` fetches
now handle 403/401 responses gracefully, matching the existing pattern
used by `DeploymentStats`, `Entitlements`, and `HealthSettings`.
- **`NetworkInfo()`**: Coordinator debug and tailnet debug fetches now
check response status codes for 403/401 before reading the body.
### `cli/support.go`
- **`summarizeBundle()`**: No longer returns early when `Config` or
`HealthReport` is nil. Instead prints warnings and continues summarizing
available data (e.g., netcheck).
### Tests
- `MissingPrivilege` → `MemberNoWorkspace`: Asserts member users can
generate a bundle successfully with degraded admin-only data.
- `NoPrivilege` → `MemberCanGenerateBundle`: Asserts the CLI produces a
valid zip bundle for member users.
- All existing tests continue to pass (`NoAuth`, `OK`, `OK_NoWorkspace`,
`DontPanic`, etc.).
## Behavior matrix
| User type | Before | After |
|---|---|---|
| **Admin** | Full bundle | Full bundle (no change) |
| **Member** | Hard error | Bundle with degraded admin-only data |
| **Unauthenticated** | Hard error | Hard error (no change) |

## Summary
The `AgentsPageView: Opens Analytics For Admins` story was flaky because
the analytics header renders a rolling 30-day date range in the
top-right corner. Since that range was based on the current date, the
story output changed every day.
This change makes the story deterministic by:
- adding an optional `analyticsNow` prop to `AgentsPageView`
- passing that value through to `AnalyticsPageContent` when the
analytics panel is shown
- setting a fixed local-noon timestamp in the story so the rendered
range label stays stable across timezones
## Summary
- include the current agent chat ID in VS Code and Cursor deep links
opened from the agent detail page
- extend `getVSCodeHref` so `chatId` is added only when provided
- add focused tests for deep-link generation with and without `chatId`
## Testing
- `pnpm -C site run format -- src/modules/apps/apps.ts
src/modules/apps/apps.test.ts src/pages/AgentsPage/AgentDetail.tsx`
- `pnpm -C site run check -- src/modules/apps/apps.ts
src/modules/apps/apps.test.ts src/pages/AgentsPage/AgentDetail.tsx`
- `pnpm -C site exec vitest run src/modules/apps/apps.test.ts`
- `pnpm -C site run lint:types`

When a PR is detected for a chat, display a compact PR badge in the
AgentDetail TopBar. On mobile it is always visible; on desktop it is
hidden when the sidebar panel is open (which already surfaces PR info)
and shown when the panel is closed.
The badge shows a state-colored icon (open, draft, merged, closed) and
the PR title or number, linking to the PR URL. Only URLs confirmed as
real PRs (via explicit `pull_request_state` or a `/pull/<number>`
pathname) trigger the badge.
## Changes
- **`TopBar.tsx`** — Added `diffStatusData` prop, `PrStateIcon` helper,
and a PR link badge between the title and actions area. Hidden on
desktop when the sidebar panel is open.
- **`AgentDetailView.tsx`** — Pass `diffStatusData` through to
`AgentDetailTopBar`.
- **`TopBar.stories.tsx`** — Added stories for open, draft, merged, and
closed PR states.
Our dogfood image already included chrome. Since we run dogfood
workspaces in Docker, chrome requires some compatibility flags to run
properly. If you launch chrome without them, some webpages crash and
fail to load.
The newest release of https://github.com/coder/portabledesktop added an
icon dock. This PR edits the chrome `.desktop` files so when you open
chrome from the dock it runs with the correct flags.

RenderBlock's file-reference variant diverged from the API (camelCase
vs snake_case), and both file variants were defined inline duplicating
the generated ChatFilePart and ChatFileReferencePart types. The
thinking and file-reference variants carried dead fields (title, text)
that were never populated by the backend.
Replace inline definitions with references to generated types, remove
dead fields, and simplify ReasoningDisclosure (disclosure button path
was dead without title).

Addresses five documentation gaps identified from an internal agents
briefing Q&A, specifically around what permissions an agent inherits
from the user:
1. **No privilege escalation** — Added explicit statement that the agent
has the exact same permissions as the user. No escalation, no shared
service account.
2. **Cross-user workspace isolation** — Added statement that agents
cannot access workspaces belonging to other users.
3. **Default-state warning** — Added WARNING callouts that agent
workspaces inherit the user's full network access unless templates
explicitly restrict it.
4. **Tool boundary statement** — Added explicit statement that the agent
cannot act outside its defined tool set and has no direct access to the
Coder API.
5. **Template visibility scoped to user RBAC** — Clarified that template
selection respects the user's role and permissions.

## Problem
When a user cancels a streaming chat response mid-stream, the partial
content disappears entirely — both from the UI and the database. The
streamed text vanishes as if the response never happened.
## Root Causes
Three issues combine to prevent partial message persistence on
interrupt:
### 1. StreamPartTypeError only matched `context.Canceled`
(`chatloop.go`)
The interrupt detection in `processStepStream` checked:
```go
errors.Is(part.Error, context.Canceled) && errors.Is(context.Cause(ctx), ErrInterrupted)
```
But some providers propagate `ErrInterrupted` directly as the stream
error rather than wrapping it in `context.Canceled`. This caused the
condition to fail, so `flushActiveState` was never called and partial
text accumulated in `activeTextContent` was lost.
### 2. No post-loop interrupt check (`chatloop.go`)
If the stream iterator stops yielding parts without producing a
`StreamPartTypeError` (e.g., a provider that silently closes the
response body on cancel), there was no check after the `for part :=
range stream` loop to detect the interrupt and flush active state.
### 3. Worker ownership check blocked interrupted persists (`chatd.go`)
`InterruptChat` → `setChatWaiting` clears `worker_id` in the DB
**before** the chatloop detects the interrupt. When
`persistInterruptedStep` (using `context.WithoutCancel`) tried to write
the partial message, the ownership check:
```go
if !lockedChat.WorkerID.Valid || lockedChat.WorkerID.UUID != p.workerID {
return chatloop.ErrInterrupted // always blocks!
}
```
unconditionally rejected the write. The error was silently logged as a
warning.
## Fix
- **Broaden the `StreamPartTypeError` interrupt detection** to match
both `context.Canceled` and `ErrInterrupted` as the stream error.
- **Add a post-loop interrupt check** in `processStepStream` that
flushes active state when the context was canceled with
`ErrInterrupted`.
- **Allow `persistStep` to write when the chat is in `waiting` status**
(interrupt) even if `worker_id` was cleared. The `pending` status (from
`EditMessage`, where history is truncated) still correctly blocks stale
writes.
## Testing
Added `TestInterruptChatPersistsPartialResponse` — an end-to-end
integration test that:
1. Streams partial text chunks from a mock LLM
2. Waits for the chatloop to publish `message_part` events (confirming
chunks were processed)
3. Interrupts the chat mid-stream
4. Verifies the partial assistant message is persisted in the database
with the expected text content
## Summary
- add shared MCP annotation metadata to toolsdk tools
- emit MCP tool annotations from both coderd and CLI MCP servers
- cover annotation serialization in toolsdk, coderd MCP e2e, and CLI MCP
tests
## Why
- Coder already exposed MCP tools, but it did not populate MCP tool
annotation hints (`readOnlyHint`, `destructiveHint`, `idempotentHint`,
`openWorldHint`).
- Hosts such as Claude Desktop use those hints to classify and group
tools, so without them Coder tools can get lumped together.
- This change adds a shared annotation source in `toolsdk` and has both
MCP servers emit those hints through `mcp.Tool.Annotations`, avoiding
drift between local and remote MCP implementations.
## Testing
- Tested locally on Cladue Desktop and the tools are categorized
correctly.

Note: Done using Coder Agents, reviewed and tested by human locally
The flat ChatMessagePart interface had 20+ optional fields, preventing
TypeScript from narrowing types on switch(part.type). Each consumer
needed runtime validation, type assertions, or defensive ?. chains.
Add `variants` struct tags to ChatMessagePart fields declaring which
union variants include each field. A codegen mutation in apitypings
reads these tags via reflect and generates per-variant sub-interfaces
(ChatTextPart, ChatReasoningPart, etc.) plus a union type alias.
A test validates every field has a variants tag or is explicitly
excluded, and every part type is covered.
Remove dead frontend code: normalizeBlockType, alias case branches
("thinking", "toolcall", "toolresult"), legacy field fallbacks
(line_number, typedBlock.name/id/input/output), and result_delta
handling. Add test coverage for args_delta streaming, provider_executed
skip logic, and source part parsing.
Transient 'No such file or directory' errors from disappearing
overlay2 layers during container operations pollute the displayed
metadata value. Redirect stderr to /dev/null.
Adds a new `site_config` entry that controls whether the virtual desktop
feature for Coder Agents is enabled. It can be set via a new
`/api/experimental/chats/config/desktop-enabled` endpoint, which will be
used by the frontend.
## Summary
Two targeted performance improvements to the chatd server, identified
through benchmarking.
### 1. RWMutex for instruction cache
The instruction cache is read on every chat turn to fetch the home
instruction file for a workspace agent. Writes only occur on cache
misses (once per agent per 5-minute TTL window), making the access
pattern ~90%+ reads.
Switching from `sync.Mutex` to `sync.RWMutex` and using
`RLock`/`RUnlock` on the read path allows concurrent readers instead of
serializing them.
**Benchmark (200 concurrent chats):**
| | ns/op |
|---|---|
| Mutex | 108 |
| RWMutex | 32 |
| **Speedup** | **3.4x** |
### 2. Hoist JSON marshaling out of persistStep transaction
`MarshalParts`, `PartFromContent`, `CalculateTotalCostMicros`, and the
`usageForCost` struct population are pure CPU work that ran inside the
`FOR UPDATE` transaction in `persistStep`. They have zero dependency on
the database transaction.
Moving all marshal and cost-calculation calls above `p.db.InTx()` means
the row lock is held only for `GetChatByIDForUpdate` +
`InsertChatMessage` calls.
**Benchmark (16 goroutines contending on same lock):**
| Tool calls | Inside lock | Outside lock | Speedup |
|---|---|---|---|
| 1 | 13,977 ns/op | 1,055 ns/op | 13x |
| 5 | 38,203 ns/op | 3,769 ns/op | 10x |
| 10 | 67,353 ns/op | 7,284 ns/op | 9x |
| 20 | 145,864 ns/op | 14,045 ns/op | 10x |
No behavioral changes in either commit.

## Summary
Remove the `hidden` tag from the `PromptCacheKey` field on
`ChatModelOpenAIProviderOptions` so the auto-generated JSON schema
no longer marks it as hidden. This allows the admin model
configuration UI to render a "Prompt Cache Key" text input for
OpenAI models alongside other visible options like Reasoning Effort,
Service Tier, and Web Search.
## Changes
- **`codersdk/chats.go`**: Remove `hidden:"true"` from `PromptCacheKey`
struct tag.
- **`site/src/api/chatModelOptionsGenerated.json`**: Regenerated via
`make gen` — `hidden: true` removed from the `prompt_cache_key` entry.
- **`modelConfigFormLogic.test.ts`**: Extend existing "all fields set"
tests to cover extract and build roundtrip for `promptCacheKey`.
## How it works
The `hidden` Go struct tag propagates through the code generation
pipeline:
1. Go struct tag → `scripts/modeloptionsgen` →
`chatModelOptionsGenerated.json`
2. The frontend `getVisibleProviderFields()` filters out fields with
`hidden: true`
3. Removing the tag makes the field visible in the schema-driven form
renderer
No new UI components are needed — the existing `ModelConfigFields`
component
automatically renders the field as a text input based on the schema
(`type: "string"`, `input_type: "input"`).
The field appears as **"Prompt Cache Key"** with description
"Key for enabling cross-request prompt caching" in the OpenAI provider
section of the admin model configuration form.
Fixes#18573
## Changes
When a `coder_app` resource sets `open_in = "tab"`, clicking the app
link now opens in a new browser tab instead of navigating in the same
tab.
`target="_blank"` and `rel="noreferrer"` are set inline on the
`<a>` elements in `AppLink.tsx`, gated on `app.open_in === "tab"`. This
follows the codebase convention of co-locating `target` and `rel` at the
render site.
`noreferrer` suppresses the Referer header to avoid leaking workspace IDs
to destination servers and implies `noopener`.
`noopener` prevents tabnabbing — without it, the opened page can
redirect the Coder dashboard tab via `window.opener`. This is especially
relevant for same-origin path-based apps, which would otherwise have
full DOM access to the dashboard.
> **Future enhancement**: template admins could opt into sending the
referrer via a `coder_app` setting, enabling feedback pages built around
workspace context.
## Tests
A vitest case is added in `AppLink.test.tsx` (rather than a Storybook
story, since the assertions are purely behavioral with no visual
component):
- **`sets target=_blank and rel=noopener noreferrer when open_in is
tab`** — renders the app link with `open_in: "tab"` and asserts
`target="_blank"` and `rel="noreferrer"` are present on the
anchor.
## Slim-window behavior
The `slim-window` test case and the `openAppInNewWindow()` comment in
`apps.ts` have been split out into a follow-up PR for separate review,
since the `window.open()` / `noopener` tradeoffs there deserve dedicated
discussion.

## Summary
Fixes four interrelated issues that caused scroll position jumps and
phantom scroll growth when paginating older chat messages.
## Changes
### 1. Removed client-side message windowing (`useMessageWindow`)
There were two competing sentinel systems: server-side pagination and
client-side windowing. The client windowing sentinel was nested deep
inside the timeline with no explicit IntersectionObserver `root`,
causing scroll position jumps when messages were prepended. Blink
(coder/blink) has no client-side windowing. Removed it entirely; server
pagination + `contentVisibility` handled performance.
### 2. Removed `contentVisibility: "auto"` from message sections
Each section had `contentVisibility: "auto"` with `containIntrinsicSize:
"1px 600px"`, causing the scroll region to grow/shrink as the browser
swapped 600px placeholders for actual heights while scrolling. This
created phantom scroll growth with no fetch involved.
### 3. Gated WebSocket on initial REST data
The WebSocket `Subscribe` snapshot calls `GetChatMessagesByChatID` (no
LIMIT) which returns every message when `afterMessageID` is 0. The
WebSocket effect opened before the REST page resolved, so
`lastMessageIdRef` was undefined, causing the server to replay the
entire history and defeating pagination. Added `initialDataLoaded` guard
so the socket waits for the first REST page.
### 4. Manual scroll position restoration
Replaced unreliable CSS scroll anchoring in `flex-col-reverse` with a
`ScrollAnchoredContainer` that snapshots `scrollHeight` before fetch and
restores `scrollTop` via `useLayoutEffect` after render. Disabled
browser scroll anchoring (`overflow-anchor: none`) to prevent conflicts.
