Adds a hidden `--chat-hook-allow-insecure` /
`CODER_CHAT_HOOK_ALLOW_INSECURE` deployment option (default `false`)
that allows the chat lifecycle hook URL to use plain HTTP for any host.
The HTTPS requirement is enforced at two points, and the flag relaxes
both: `DeploymentValues.Validate()` rejects `http` hook URLs at startup,
and the hook dispatcher's `validateHookURL` allows `http` only for
loopback hosts. With the flag set, any-host `http` is accepted; the
host, fragment/userinfo, secret, and timeout checks are unchanged, and
non-http(s) schemes still fail. This removes the need for an HTTPS
reverse proxy when testing a hook consumer on a trusted network.
Following security review feedback, the flag description and docs state
that plain HTTP lets an on-path attacker forge hook responses (which
control agent execution), and `coder server` logs a startup warning
(with a redacted hook URL) when hooks run over plain HTTP.
Docs, generated API types, and the server config golden are updated
accordingly.

## What
Adds CI enforcement that fails when docs Markdown contains invalid
inline HTML
the docs site silently drops or mangles, and fixes the remaining
generated-doc
placeholders at their source.
This is the tooling half of the docs-HTML audit. The hand-written fixes
it
guards landed in #27298 (kept small and separate so it reviewed fast);
this PR
carries everything that touches code, CI, or generated output.
## Changes
**Linter (`scripts/docshtmlcheck`), wired into `make lint` via
`lint/docs-html`.**
Markdown-aware: parses each file with goldmark and inspects only
raw-HTML nodes,
so angle brackets in fenced code blocks, inline code, HTML comments, and
`<https://…>` / `<user@host>` autolinks are ignored. Flags swallowed
placeholders (`<region>`), void-element end tags (`</br>`), unregistered
or
incorrectly capitalized component tags (`<Image>`), and unclosed
container tags (a
`<div class="tabs">` that leaks its wrapper). The one intentional
renderer
component, `<children>`, is allowed but still balance-checked.
**Generator-source placeholder fixes (regenerated via `make gen`).**
- `codersdk/chats.go`: backtick `<server>__` in the
`ChatContextTool.Name` doc
comment (it becomes the Swagger description, so it was swallowed in
`reference/api/{chats,schemas}.md`).
- `codersdk/deployment.go`: backtick `<region>` in the AWS Bedrock
region flag
help (swallowed in `reference/cli/server.md`); also updates `coder
server
--help` output and the golden files.
**Temporary allowlist.** `docs/reference/cli/agent-firewall.md`'s
`<host>` /
`<glob>` come from the external `github.com/coder/boundary` CLI help
(still
`v0.10.0` on `main`), so they are suppressed on that one file. The
suppression
is self-clearing: if an allowlisted tag stops appearing on a scanned
file, the
linter reports `stale-allowlist-entry` and fails until the dead entry is
removed, so a dead entry cannot silently mask a later regression of that
tag on
that page. (An entry whose file is deleted outright is never rescanned,
but a
missing file yields no findings, so nothing hides behind it either.)
## Review feedback addressed
This tool + generator work was reviewed by Coder Agents Review while it
was
bundled into #27298. Addressed here:
- **P1:** tokenize each raw-HTML node as a whole instead of per source
line, so
a tag whose attributes wrap across lines is no longer torn in half. This
fixes
both the missed multi-line unclosed `<div>` (a leaked wrapper that
passed with
exit 0) and the spurious `stray-end-tag` on valid multi-line tags. Each
token
maps back to its own source line.
- Normalize allowlist lookup/report paths to a canonical repo-relative
form, so
the escape hatch no longer silently misses under absolute / `./` paths.
- Route generated-page findings to the generator source.
- Add `<search>` to the allowed set; reword the unknown-element message
to note
that a real element can be added to `allowedElements`.
- Self-clearing allowlist guard (above); rename `optionalEndTag(s)` and
`kindUnclosed(Tag)`; adopt `slices`/`maps` idioms; move the lint banner
to the
Makefile recipe; stop aliasing the input slice in `filterAllowed`.
- New tests: multi-line tokenization (both classes), interleaved
nesting, a
pinned line number, `collectMarkdown`, and the stale-allowlist guard.
### Round 2 (Coder Agents Review on this PR)
A second `/coder-agents-review` pass on this PR raised 16 findings;
addressed in
`fix(docshtmlcheck): catch self-closing containers and capitalized
tags`:
- **P2:** self-closing container tags (`<div class="tabs"/>`) were
ignored by
the HTML5 parser and leaked their wrapper like the open spelling; the
balance
check now tracks self-closing tokens too (CRF-1).
- **P2:** a capitalized component tag whose lowercase name is a real
element
(`<Table>`, `<Section>`) slipped through on the `allowedElements`
lookup. The
tokenizer lowercases tag names, so the check now reads the raw token and
reports any capitalized name as a component reference (CRF-2).
- Narrowed the `:` / `@` autolink skip to a real URI scheme or a dotted
`local@domain`, so `<region:id>` and `<user@host>` stay checked (CRF-3).
- Stale-allowlist findings now report against the linter source with no
line,
and count separately from invalid-HTML issues in the footer (CRF-7,
CRF-11).
- Comment / README / Makefile wording synced to the honest
capitalized-tag
behavior; added the deleted-file allowlist caveat and a note that
`allowedElements` is hand-maintained against the renderer (CRF-14,
CRF-17,
CRF-9).
- Internal cleanups (`pop` -> `matchEndTag`, extracted
`unclosedFinding`) and
new tests: self-closing, capitalized open/close, colon/at placeholders,
a
non-first-token line assertion, `isGeneratedDoc`, and the stale message
(CRF-12, CRF-13, CRF-1/2/3/4/5/16).
Two findings resolved without a code change:
- **CRF-8** (also wire `lint/docs-html` into `lint-light`): declined.
`lint-light` is the Go-free fast path; `lint/docs-html` needs the Go
toolchain, so it stays in the full `make lint`, which CI runs. Adding it
would
pull Go into the light path for no coverage gain.
- **CRF-9** (`allowedElements` <-> renderer coupling): documented with a
maintenance note in the `allowedElements` comment and tracked in
DOCS-597 for
a cross-repo sync/check decision.
Deferred (note, no current trigger): raw-text element interiors
(`<script>` / `<style>`) are not scanned for nested tags. No docs page
relies
on this today; noted for follow-up.
## Merge order
#27298 (the hand-written fixes this PR guards) has merged, and this
branch is
rebased on `main`, so `make lint/docs-html` now reports 0 findings and
the
`lint` check passes. The two PRs are independent (disjoint files, no
stacking).
## Verification
- `go test ./scripts/docshtmlcheck/`, `go vet`, `gofmt -l`,
`golangci-lint run`: clean.
- `make lint/docs-html` (branch rebased on `main`): 0 findings.

> This PR was created with AI assistance (Coder Agents).
Wires chat lifecycle hooks into chatd, gated by the
`agent-lifecycle-hooks` experiment. Part of the lifecycle hooks stack
(#27401, #27428, #27430). See `docs/admin/setup/chat-lifecycle-hooks.md`
for the consumer-facing contract.
## Summary
When a hook URL is configured, chatd dispatches `session_start`,
`user_prompt_submit`, `pre_tool_use`, `post_tool_use`, `pre_compact`,
`post_compact`, and `stop` events to the consumer and applies its
responses.
## Design
- **Stateless**: Coder stores no hook dispatch or decision state.
Delivery is at least once; consumers deduplicate on stable payload
identifiers (chat ID, event type, tool-use ID) and answer duplicates
with the same decision.
- **Admission-time prompt effects**: `user_prompt_submit` dispatches
exactly once per submission (create, send, queue, edit, subagent spawn)
and folds its effects into the stored prompt as typed message parts:
original-or-overridden user parts, then model-only `hook-context`, then
a user-visible `hook-notice`. Hook context is stripped from every
client-facing conversion; hook notices are excluded from model prompts.
The server rejects hook parts in client-submitted content.
- **Tool gating**: `pre_tool_use` allow can override tool input; deny
becomes a synthetic denied tool result, with any returned model context
persisted as a model-only transcript row so it never reaches clients.
The denial text identifies an external policy (the deployment's
lifecycle hook) as the source and marks the decision as persistent, so
the model explains the denial instead of retrying it or misreporting it
as an infrastructure failure.
- **Fail closed**: a dispatch failure rejects the triggering request or
moves the chat to the error state in the same transaction as the
affected step, so a runnable state is never published with unapproved
content.
- **Admission before persistence**: `pre_tool_use` is dispatched for the
calls the model produced, before the assistant message is stored. See
"Staged tool admission" below.
- **Fresh dispatch per tool call**: every non-provider-executed tool
call is decided by its own `pre_tool_use` dispatch; Coder never reuses
an earlier decision on the consumer's behalf. Retries re-dispatch the
same logical event.
## Structure
All hook dispatch flows through one seam: entry points build a
`chathooks.Chat` (chat identity) and a `chathooks.Message` (event
details) and call `Trigger.Trigger`, the only component that talks to
the dispatcher. The integration lives in the `coderd/x/chatd/chathooks`
subpackage, split by responsibility:
- `trigger.go`: the trigger seam; builds the wire envelope per event,
normalizes deny into a typed error, and holds the package's single
enabled-check.
- `effects.go`: pure conversion of hook results into transcript rows and
prompt parts.
- `errors.go`: failure classification (dispatch error messages, denial
mapping, tool-result dispatch-failure scanning).
- `tooluse.go`: the tool-call gate (`pre_tool_use` preflight,
`post_tool_use` payloads, applying admitted input to the step).
Server-bound glue stays in `coderd/x/chatd/hook_server.go`: the
chat-parking dispatch error handlers, the step-commit row insertion
wrappers, and the dynamic post-tool-use state loader, which depends on
chatd validation types.
This PR adopts the `codersdk/x/agenthooks` and
`coderd/x/agenthooks/dispatch` import paths introduced at the tip of
#27401; intermediate commits still reference the pre-move paths and are
not individually buildable.
## Staged tool admission
`pre_tool_use` originally ran at tool execution time, which is after the
assistant message carrying the tool call was already committed. An
`input_override` therefore had to rewrite stored message content in
place. @hugodutka pointed out that chatd treats message content as
immutable, and that the rewrite was a shortcut rather than a
requirement.
It was also a correctness problem in its own right: the rewrite only
updated the database, so the transcript could show one input while a
different one had executed.
The hook now runs before the step is persisted:
```text
provider stream ends (tool calls complete, in memory)
-> pre_tool_use dispatch per call
-> ONE transaction: assistant row with admitted inputs, synthetic denials, hook rows
-> execute
```
The step is inserted once, carrying the input the tool runs with.
`UpdateChatMessageContentByID` and `Tx.UpdateMessageContent` are deleted
from #27428, so message content stays immutable.
Two consequences, both intentional:
- **Clients converge rather than wait.** Tool-call parts still stream
live, so a rewritten call briefly shows the model's proposed input
before the committed message replaces it. The chat store already clears
stream state when an assistant message arrives, so the stored input wins
with no frontend change and no added latency before tool cards appear.
- **A call already in history was already admitted.** Execution consumes
the stored input instead of dispatching a second decision, which keeps
one dispatch and one set of hook effects per call. A consumer policy
change between admission and execution applies to later calls, not to
calls already admitted.
The per-chat debug endpoint still records the provider's original tool
input. Its purpose is to report provider behavior, and it requires an
explicit per-chat debug flag; the invariant here covers the transcript.
## Configuration
Adds `chat-hook-url`, `chat-hook-secret`, `chat-hook-timeout`, and
`chat-hook-enabled` deployment options with startup validation. The
flags are hidden from `coder server --help` while the feature is
experimental; the setup guide documents them.
## Tool input validation
Built-in tool arguments reach a consumer as raw JSON with key spelling
preserved, but the tools decode those bytes with Go, which matches
struct fields case-insensitively and keeps the last match. A policy
reading `path` could therefore authorize one value while the tool
executed another, and a lone case variant such as `{"PATH":"/secret"}`
was invisible to a policy checking for `path`.
Coder now rejects a built-in tool call whose input repeats a key or
spells a schema property with different capitalization, before the
`pre_tool_use` dispatch, so a consumer is never asked to authorize bytes
whose meaning depends on the reader. Rejected calls produce an error
result the model can retry; unambiguous calls in the same batch still
run. A consumer-authored `input_override` is rechecked after the
dispatch and fails the turn closed, because the model cannot correct it.
Dynamic and MCP inputs are excluded because the client and the workspace
agent execute those calls rather than coderd.
Two paths needed more than a schema check. Execution resolves a
deprecated tool name to its canonical tool, so validation resolves
aliases first. The `edit_files` decoder also reads `search` and
`replace`, which its schema does not advertise, so those aliases are now
matched exactly and their case variants ignored.
A hook denial now returns a structured 403 carrying `kind:
"hook_denied"`, mirroring the dispatch-failure response that already
carries its own kind. Without it a client cannot tell a policy decision
apart from a generic failure, and the chat UI titled a denial "Request
failed". Adding a kind needs no migration: `ChatErrorKind` is persisted
only inside the JSONB `chats.last_error` column, whose decoder accepts
unknown kinds.
The hook docs also correct the tool-input convergence window. A batch
dispatches sequentially before the assistant row commits, so the
original input stays visible for a span that scales with the number of
tool calls in the step rather than a single hook timeout.

## Problem
Generated reference docs (`docs/reference/cli/*`,
`docs/reference/api/*`) contained raw placeholder and JSON syntax that
came straight from Go CLI help strings and swagger annotations. HTML
renderers treat the angle-bracket tokens (`<team-slug>`, `<uuid>`,
`<KEY>`, etc.) as unknown tags and drop them, so readers see
broken/half-missing text today. The same strings also break MDX parsing.
## Fix
Wrap the placeholder/JSON syntax in backticks **at the source** (Go help
strings and swagger annotation comments), then `make gen`. Rendered docs
now show the placeholders as inline code instead of dropping them.
### Source changes
| File | Placeholder wrapped | Surfaces in |

`{'tag1':'value1','tag2':'value2'}` `` | `api/organizations.md`,
`api/provisioning.md` |
Everything else in the diff (`coderd/apidoc/*`, `docs/reference/**`,
`*.golden`, `site/src/api/typesGenerated.ts`) is `make gen` output.
## Reviewer notes (the "considered pass" from the ticket)
- **Product-visible:** this changes `coder server --help` and `coder
tokens create --help` output, and the `server-config.yaml` reference
comment. Backticks in terminal help are literal but read fine as
placeholder markers.
- **Settings UI:** the `deployment.go` `Description` also renders in the
deployment settings page. If that field is not Markdown-rendered,
literal backticks will show there. Happy to drop the `deployment.go`
change if you'd rather keep the UI text clean and fix `server.md`
another way.
- **Out of scope here:** `docs/reference/cli/agent-firewall.md`
(`<host>`/`<glob>`) is generated from the external
`github.com/coder/boundary` module, not this repo. It needs an upstream
fix + module bump; not included in this PR.
<details>
<summary>Implementation notes / decision log</summary>
- Scope taken from DOCS-551: source-level backtick pass for generated
reference docs only. Hand-written Markdown fixes are tracked separately
(companion ticket).
- Swagger `@Param` descriptions are Go comments, so the existing `\|`
pipe-escaping in the chats `q` filter is preserved inside the new
backticks (still required for the Markdown table cell to render `|`).
- Verified after `make gen`: generated docs render placeholders as code
spans, table pipes intact; `gofmt` clean; changed Go packages build; no
emdash/endash introduced.
- Deliberately left the `AIProviderConfig` type-level doc comment
untouched because it does not surface in any generated doc (kept the
diff to doc-feeding comments).

## Evidence: placeholders dropped on the live docs site
Verified **2026-07-14** against the live site (`coder.com/docs`, i.e.
`main`, pre-merge) by loading each affected page in headless Chrome and
reading the post-hydration DOM (confirmed identical in the raw page
payload). Each simple `<token>` placeholder is parsed as an **empty
custom HTML element**, so the browser renders nothing for it and the
placeholder text disappears from the page.
### What readers see today (before this PR)

### Accuracy note — cases that do *not* drop on live
These render fine today, so they are **not** evidence of dropping (the
PR still wraps them for consistency / MDX-safety):
-
[`api/organizations`](https://coder.com/docs/reference/api/organizations)
and
[`api/provisioning`](https://coder.com/docs/reference/api/provisioning):
`{'tag1':'value1','tag2':'value2'}` renders verbatim — curly braces are
not an HTML tag.
- Tokens containing `/` or `|` are escaped by the renderer and stay
visible (as literal `<...>`): `<username/uuid/me>`, `<org-name/uuid>`,
`<owner/repo>`, `<draft|open|merged|closed>`,
`<created_by_me|shared_with_me>`. Backticks still improve their
readability, but they were never dropped.
Adds `--aigateway-proxy-target` option to
`deploymentGroupAIGatewayProxy` that defines URL to which intercepted
requests should be forwarded to.
Forward URL used to be hardcoded to `coderAPI.AccessURL` pointing to
embedded Gateway. With addition of standalone AI Gateway this needs to
be configurable.
Renamed `aibridgeproxyd.Server.coderAccessURL` and `coderAccessPort` ->
`gatewayURL` and `gatewayPort` + option to better reflect reality.
This PR adds a new opt-in setting, `CODER_OIDC_REDIRECT_ALLOWED_HOSTS`,
that lets a single Coder deployment complete OIDC login on more than one
hostname. When the allowlist is non-empty, Coder picks the OIDC
`redirect_uri` based on the incoming request's Host header (validated
against the list) instead of always using the static URL derived from
`CODER_ACCESS_URL`. When unset, the (default) behavior is identical to
today.
The motivation is that a single Coder deployment is frequently reachable
via multiple hostnames - for example, an internal hostname for users on
a corporate VPN and a different hostname routed through a zero-trust
gateway for users off-VPN - but OIDC login today only works on whichever
single hostname `CODER_ACCESS_URL` points to, because the `redirect_uri`
sent to the IdP is fixed at server startup. Users who reach the
deployment on any other valid hostname can see the login page but fail
the OIDC callback, since the IdP redirects them back to a hostname they
can't reach (or whose cookies they don't have).
This PR removes the now-dead direct-routing code:
- Deletes the direct routing implementation.
- Collapses the resolvedModelRoute discriminated union into aiGatewayModelRoute.
- Removes the dead providerKeys cascade.
- Deletes the preferredShortTextCandidates quickgen function.
- Simplifies the advisor override error handling.
- Deprecates the AIGatewayRoutingEnabled deployment option. It is now a no-op so as to not break existing deployments on upgrade.
Once direct routing was gone, the AI Gateway became mandatory for chat, which surfaced gaps in how the product behaves with the gateway disabled:
- Exposes ai-gateway-enabled to the frontend via embedded page metadata.
- Disables the chat composer via the existing AgentSetupNotice when the gateway is disabled, for both new and existing chats.
- Fixes nil/typed-nil chatDaemon panics on startup and shutdown when gateway is disabled.
- Fixes chat WebSocket from retrying the still-gated stream endpoint forever when the gateway is disabled.
Rename user-facing "AI Bridge" strings to "AI Gateway" in deployment
config, RBAC display names, log messages, error strings, docs style
guide, and Grafana dashboard README.
Deprecated option names and descriptions (the `--aibridge-*` block) are
intentionally kept as "AI Bridge". The `Name` field cannot be renamed
because `serpent` uses it as a unique key during JSON serialization;
duplicating names causes `UnmarshalJSON` failures (e.g. in the support
bundle). Descriptions also stay as "AI Bridge" to avoid confusion
between the deprecated and primary options.

## Backend fixes
1. **Registry URL scheme fix**: Default
`CODER_TEMPLATE_BUILDER_REGISTRY_URL` was `https://registry.coder.com`
but Terraform module registry addresses must be scheme-less. Changed to
`registry.coder.com`.
2. **Sensitive variable defaults**: Module `.tf.tmpl` files for
claude-code, aider, amazon-q had sensitive `variable` blocks without
`default`, causing `terraform plan` to fail during template import. Also
fixed the `templatebuildermodulegen` script.
3. **Auto-quote string variables**: The backend now accepts raw string
values from callers and wraps them in HCL quotes automatically.
Previously callers were required to send pre-quoted HCL literals, which
is not a reasonable API contract.

Add a periodic purge job for `boundary_logs` rows past their retention
threshold, following the same pattern as the existing audit log and
connection log purge jobs in `dbpurge`.
Expose a `--boundary-log-retention` deployment flag (env
`CODER_BOUNDARY_LOG_RETENTION`, YAML `retention.boundary_logs`). Default
is `0` (keep indefinitely). When set to a positive duration, `purgeTick`
deletes rows where `captured_at` is older than the threshold in batches
of 10,000, matching other log purge operations. The `boundary_logs`
label is added to the `records_purged_total` Prometheus counter.
Also removes the random-UUID fallback for `OwnerID` in
`dbgen.BoundarySession`. The previous fallback generated a UUID that
could never satisfy the `boundary_sessions_owner_id_fkey` FK constraint,
masking test setup bugs. Callers must now provide a valid user ID or
accept NULL (the legitimate "user deleted" state).
Subdomain app routing derived the app identity from
httpapi.RequestHost, which returned the client-supplied
X-Forwarded-Host header verbatim. No middleware validated or stripped
that header, so a request from an untrusted peer could forge it. Since
the application_connect cookie is scoped to the wildcard apps domain,
JavaScript in a share=authenticated app could fetch() with a forged
X-Forwarded-Host pointing at a victim's owner-only app; coderd routed
and authorized the request as the victim and returned the private app
response same-origin to the attacker.
Replace RequestHost with httpmw.EffectiveHost, which honors
X-Forwarded-Host only when the original socket peer is a configured
trusted origin, otherwise falling back to the received Host header.
This ties host trust to the same RealIPConfig model already used for
X-Forwarded-For and -Proto. Wire it into HandleSubdomain for both
coderd and wsproxy, and log both the effective host and the raw
received_host.
Add coverage: EffectiveHost unit tests assert the trust decision uses
the socket peer rather than the spoofable forwarded client IP, and a
HandleSubdomain test confirms a forged X-Forwarded-Host from an

Reverts coder/coder#26239
We cannot disable a feature which was previously enabled; this is a BC
break.
This is also using `AIGatewayRoutingEnabled` which will be removed in
the next release.
Problem: CODER_AI_GATEWAY_ENABLED defaulted to true, which both started
the in-memory gateway and enabled the licensed FeatureAIBridge. As a
result, deployments that never configured AI Gateway saw a spurious "AI
Governance add-on is required" warning whenever they had an older
(non-add-on) Premium license, since the feature was enabled-and-entitled
by default.
Fix: Decouple "external AI Gateway API enabled" from "in-memory daemon
running," so the external/licensed surface is off by default while Coder
Agents retain access by default.
- Adds server-side and client-side validation for
CODER_CONFIGSSH_HOSTNAME_SUFFIX and CODER_SSH_CONFIG_OPTIONS.
- **Server-side breaking change:** invalid values for either of these will cause `coderd` to exit with an error.
- Client-side: `coder config-ssh` will exit with an error if it detects invalid config.
- Adds tests for the above
Local smoke-testing: ran `develop.sh --env-file <path to an env file
containing badness>`. Validated that server startup failed as expected.

## Summary
Routes chatd model calls backed by concrete AI Provider rows through the
in-process aibridge transport by default, with deployment options to use
direct provider routing when AI Gateway is disabled or chat AI Gateway
routing is disabled.
- Splits model routing into common, direct provider, and AI Gateway
paths behind a single deployment-mode entry point.
- Builds chatd models through explicit request, route, and options data.
Active API key attribution is passed explicitly instead of being hidden
inside generic model construction.
- For AI Gateway BYOK routes, resolves the user's provider key in chatd,
forwards it through provider-specific auth headers, and sets
`X-Coder-AI-Governance-Token` to the `delegated` marker so aibridge
preserves those headers while still stripping Coder-specific metadata.
- Keeps central provider credentials and deployment fallback credentials
out of forwarded provider auth headers, so AI Gateway central policy
remains authoritative.
- Redacts delegated provider auth from default string formatting to
avoid accidental plaintext logging of user BYOK credentials.
- Covers selected chat models, advisor overrides, title and quickgen
paths, subagent overrides, computer use model selection, and an
integration-style chat turn through the aibridge transport path.
- Persists initiating API key IDs on chat and queued user messages,
including subagent child messages, and fails closed for AI
Gateway-routed model builds without an active key.
- Removes unused `api_key_id` indexes while keeping the persistence
columns and foreign keys.
- Keeps the deployment option available through config and env parsing,
but hides it from CLI help and generated docs.
- Stabilizes the subagent poll fallback test so background CreateChat
processing cannot win the state transition under slower CI environments.

> Mux working on behalf of Mike.
Replace the env-based `BuildProviders` with a DB-backed loader. The database is now the single source of truth for runtime provider configuration; env config arrives via `SeedAIProvidersFromEnv` (run at boot) and `BuildProviders` reads it back as `aibridge.Provider` instances. `cli/server.go` and `enterprise/cli/server.go` both call the same path, so aibridged and aibridgeproxyd see the same provider set.
Per-provider `DumpDir` is replaced by a top-level `CODER_AI_GATEWAY_DUMP_DIR` base; each provider's effective dump path is `<base>/<provider name>`.
`CODER_AI_GATEWAY_ENABLED` / `CODER_AIBRIDGE_ENABLED` is now being defaulted to `true` now that it will be used by Coder Agents.
If you previously had this value disabled explicitly, that value will persist.
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.

## Description
Removes 429 (Too Many Requests) from the circuit breaker failure conditions. Rate limiting is now handled by automatic key failover instead of tripping the circuit breaker.
## Changes
`DefaultIsFailure` no longer treats 429 as a circuit breaker failure. The circuit breaker now only trips on server overload responses (503, 529).
Tests and integration tests updated to use 503 instead of 429 for tripping circuits. Description strings in deployment config updated to reflect the change.

## Summary
Adds `--ai-gateway-allow-byok` deployment option to control whether
users can use Bring Your Own Key (BYOK) mode with AI Gateway.
When disabled (`--ai-gateway-allow-byok=false`), BYOK requests are
rejected with a 403 and a message directing the admin to enable the
flag. Centralized key authentication works regardless of this setting.
Defaults to `true` (BYOK allowed).

## Summary
- Support multiple instances of the same AI Bridge provider type via
indexed env vars (`CODER_AIBRIDGE_PROVIDER_<N>_<KEY>`), following the
`CODER_EXTERNAL_AUTH_<N>_<KEY>` pattern
- Existing single-provider env vars (`CODER_AIBRIDGE_OPENAI_KEY`, etc.)
continue to work unchanged
- Setting both a legacy env var and an indexed provider with the same
name errors at startup to prevent silent misconfiguration
- Mark legacy provider fields (`OpenAI`, `Anthropic`, `Bedrock`) as
deprecated in `AIBridgeConfig` in favor of `Providers`
## Example
```sh
CODER_AIBRIDGE_PROVIDER_0_TYPE=anthropic
CODER_AIBRIDGE_PROVIDER_0_NAME=anthropic-corp
CODER_AIBRIDGE_PROVIDER_0_KEY=sk-ant-corp-xxx
CODER_AIBRIDGE_PROVIDER_0_BASE_URL=https://llm-proxy.internal.example.com/anthropic
CODER_AIBRIDGE_PROVIDER_1_TYPE=anthropic
CODER_AIBRIDGE_PROVIDER_1_NAME=anthropic-direct
CODER_AIBRIDGE_PROVIDER_1_KEY=sk-ant-direct-yyy
```
Each instance is routed by name:
- /api/v2/aibridge/**anthropic-corp**/v1/messages
- /api/v2/aibridge/**anthropic-direct**/v1/messages

## Description
Adds support for multiple Copilot provider instances to route requests to different Copilot upstreams (individual, business, enterprise). Each instance has its own name and base URL, enabling per-upstream metrics, logs, circuit breakers, API dump, and routing.
## Changes
* Add Copilot business and enterprise provider names and host constants
* Register three Copilot provider instances in aibridged (default, business, enterprise)
* Update `defaultAIBridgeProvider` in `aibridgeproxy` to route new Copilot hosts to their corresponding providers
## Related
* Depends on: https://github.com/coder/aibridge/pull/240
* Closes: https://github.com/coder/aibridge/issues/152
Note: documentation changes will be added in a follow-up PR.

## Description
Blocks `CONNECT` tunnels to private and reserved IP ranges in
aibridgeproxyd, preventing the proxy from being used to reach internal
networks.
The Coder access URL is always exempt (hostname+port match) so the proxy
can reach its own deployment. It is possible to exempt additional ranges
via `CODER_AIBRIDGE_PROXY_ALLOWED_PRIVATE_CIDRS`.
DNS rebinding is handled differently per path:
* Direct (no upstream proxy): validate the resolved IP right before the
TCP dial, no window between check and connect.
* Upstream proxy: Resolves and checks before forwarding to the upstream
dialer. A small rebinding window exists since the upstream proxy
re-resolves independently.
## Changes
* Add blocked IP denylist covering private, reserved, and
special-purpose ranges
* Add `AllowedPrivateCIDRs` option with CLI flag and env var
* Wire IP checks into `proxy.ConnectDial` for both upstream and direct
paths
* Add tests for blocked/allowed cases across direct dial, upstream
proxy, CIDR exemptions, and CoderAccessURL exemption
Notes: documentation will be handled in a follow-up PR.
Closes: https://github.com/coder/security/issues/124
## 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.
_Disclaimer: implemented by a Coder Agent using Claude Opus 4.6._
Marks the injected MCP approach in AI Bridge as deprecated across the
codebase.
## Changes
- **`codersdk/deployment.go`**: Deprecated `ExternalAuthConfig.MCPURL`,
`.MCPToolAllowRegex`, `.MCPToolDenyRegex` fields; deprecated and hid the
`--aibridge-inject-coder-mcp-tools` server flag; deprecated
`AIBridgeConfig.InjectCoderMCPTools`.
- **`coderd/externalauth/externalauth.go`**: Deprecated `Config.MCPURL`,
`.MCPToolAllowRegex`, `.MCPToolDenyRegex`.
- **`enterprise/aibridgedserver/aibridgedserver.go`**: Added runtime
deprecation warning when `CODER_AIBRIDGE_INJECT_CODER_MCP_TOOLS` is
enabled; deprecated `getCoderMCPServerConfig`.
- **`enterprise/aibridged/mcp.go`**: Deprecated `MCPProxyBuilder`
interface and `MCPProxyFactory` struct.
- **`docs/ai-coder/ai-bridge/mcp.md`**: Added deprecation warning
banner.
## Description
Adds optional TLS support for the AI Bridge Proxy listener. When TLS cert and key files are provided, the proxy serves over HTTPS instead of plain HTTP.
## Changes
* New configuration options to enable TLS on the proxy listener
* Wraps the TCP listener in `tls.NewListener` when configured
* Tests for validation errors, invalid files, and full integration (tunneled + MITM) through a TLS listener
Note: Documentation for TLS listener setup and client configuration will be handled in a follow-up PR.

## Description
Renames internal fields, variables, and comments related to the proxy's certificate/key configuration to explicitly reference their MITM CA purpose.
The AI Bridge Proxy uses a CA certificate to sign dynamically generated leaf certificates during MITM interception of HTTPS traffic from AI clients. With the upcoming introduction of TLS listener certificates (for serving the proxy itself over HTTPS, implemented upstack https://github.com/coder/coder/pull/22411), the previous generic naming would become ambiguous. This refactor makes it clear which certificate is which.
No user-facing flags, environment variables, YAML keys, or JSON fields were changed, this is purely an internal rename to avoid confusion going forward.
Related to https://github.com/coder/internal/issues/1335
`--secure-auth-cookie` now automatically sources it's default value from `--access-url`
If the access url uses HTTPS, secure is set to `true`.
To revert to old behavior, set the value explicitly to `false`
If a deployment has 2 domains, overriding the oidc url allows the oidc
redirect to differ from the access_url
response to https://github.com/coder/coder/discussions/21500
**This config setting is hidden by default**
## Description
Mark `--ssh-hostname-prefix` flag and `CODER_SSH_HOSTNAME_PREFIX` env
variable as deprecated, recommending users to use
`--workspace-hostname-suffix` / `CODER_WORKSPACE_HOSTNAME_SUFFIX`
instead for consistency with Coder Desktop.
The deprecated option is now hidden from help output and docs but
remains functional for backward compatibility. When used, it will show a
deprecation warning pointing to the recommended alternative.
## Changes
- Added `UseInstead` pointing to `workspace-hostname-suffix` option
(triggers deprecation warning)
- Set `Hidden: true` to hide from CLI help and documentation
- Updated description to mention deprecation
- Regenerated docs and help files via `make gen`
Closes#18156

This undeprecates the `allow-workspace-renames` flag. IIUC, the 'danger'
with using this flag is that the workspace name might have been used in
the definition of some other terraform resources within template code,
so a rename could cause problems such as with persistent disks.
