Conversation
New discord-bot worker: members with an allowed role submit tasks from an allowed channel via /task (repo autocomplete). The bot opens a thread per task, posts the result there, and treats /task in a task thread as a follow-up. Sessions use the Claude Agent harness by default so a connected Claude subscription can pay for them. Control plane: register discord-bot as a service, actor namespace, callback destination, and message/spawn source; grant it actorless reads of repos, events, and artifacts. Terraform: enable_discord_bot and discord_* variables, worker, KV, service-auth secret, control-plane binding, and tests.
Post a status message in the task thread when a prompt is sent, edit it with elapsed time and recent steps as tool-call callbacks arrive (with a typing indicator), and mark it finished before posting the result.

[Automated Review] Requesting changes: the Discord package itself is tidy, but how it plugs into the existing system needs another pass.
packages/discord-bot is small and well-organized (no file near 300 lines, clean module boundaries, Zod at the edges), and Discord is registered correctly in SERVICE_NAMES, ASSERTION_RIGHTS, ACTOR_NAMESPACES, CALLBACK_DESTINATIONS, the permission ceilings and the Terraform/AWS secret wiring. The shared completionCallbackPayloadSchema/toolCallCallbackPayloadSchema factories are a nice extraction.
The issues are in the integration seams. Each finding is an inline comment below. Where possible I checked it with a throwaway probe test on 5f1889a (not committed) and say so in the comment.
Suggested order:
- Finish the callback route table so each route owns its post gate and denial behavior (control-plane
callback-notification-service.tsL92 + L227). This removes the remaining per-bot branches and gives Discord a way to stop showing "Working…" when a callback is refused. - Registration gaps: the hand-written spawn-source lists and the stale trace-export schema, the
team-ownership.tsrefusal list, and the coverage/smoke/docs/tftest files. - Discord-bot conformance: shared tool-status formatter (also fixes the URL-mangling bug),
_MSdurations +createKvCacheStore, thread-session store module, callback route hardening + tests,team_requiredmessaging, harness config. - Minor cleanups.

[Automated Review] Callback route table is only half-built: per-bot behavior still lives in branches around it.
The table is the right direction, but it only carries destination/binding/schemas. Bot-specific behavior is still scattered:
channelPostDenialbranches ondestination === "slack-bot"/"discord-bot"- the tool-call path checks
route.destination === "slack-bot" || route.destination === "discord-bot" args: route.toolCallSchema ? event.args : (event.args ?? EMPTY_TOOL_ARGS)(L824) uses schema presence as a proxy for "legacy Slack contract". Verified with a probe test: a Slack tool call without args is sent withargs: {}, the identical Discord call is dropped asinvalid_payload.- denial paths still call
hasSlackThreadCoordinates/notifySlackThreadClosedfor every route; for Discord they no-op only because the context happens to lack Slack fields.
Suggestion: let the route own its behavior, e.g. postGate(sessionId, context) and an optional onDenied(...) (Slack's thread-closed), plus an explicit defaultArgs/legacy flag if still needed. Key the table on MessageSource (Partial<Record<MessageSource, CallbackRoute>>) like ASSERTION_RIGHTS / SERVICE_PERMISSION_CEILINGS. channelPostDenial and the destination checks then disappear. Extracting the routes into callback-routes.ts would also keep this file (now 926 lines) well clear of 1k.

[Automated Review] Discord reuses slackPostGate(session, null), which overloads a Slack-specific concept and leaves the Discord status message stuck.
- Verified with a probe test: a workspace-visible, team-owned Discord session is refused with
reject_reason: "channel_team_mismatch", though Discord has no channel bindings. The PR's own test (callback-notification-service.test.ts L763-783) asserts the same. - In the refused case nothing at all reaches
DISCORD_BOT(verified for both completion and tool-call paths). The bot only finishes its status message from the completion callback, so it stays "⏳ Working…" forever.DISCORD.mddocuments that updates stop, but Slack gets athread_closednotice for this case and Discord gets no equivalent. - The
slackPostScopedependency now gates Discord too.
Suggestion: give Discord a named gate (e.g. teamlessPublicationGate) with its own reason code, rename the scope dep to something channel-neutral, and (with onDenied from the route-table comment) send Discord a coordinates-only "stopped" callback so the bot can mark the status message finished.

[Automated Review] discord-bot was granted actorless /repos but not added to the ?teamId= refusal in routes/team-ownership.ts:66.
That check refuses ?teamId= from slack-bot and linear-bot by name. Verified with an integration probe against /repos?teamId=<team> (member actor):
- slack-bot: 404 actorless, 404 with actor (refused)
- discord-bot: 404 actorless, passes the team gate with an actor (then 500
SCM provider not configuredin the test env, i.e. it reached the handler)
This is latent today (the bot never sends an actor or teamId on /repos), and the passing case only exposes grants for a team the actor belongs to. But it's the kind of list the next bot will also miss. Please either add discord-bot there or, better, turn the check into an allow-list or derive it from a shared set.

[Automated Review] Spawn-source list extended by hand instead of consolidated.
pull-request-analytics-store.ts was correctly switched to spawnSourceSchema, but "discord-bot" was appended to two other hand-maintained copies: here and control-plane/src/session/http/handlers/session-init.handler.ts:22. Per AGENTS.md ("fix bad names or units in the same change rather than spreading the problem"), both should import spawnSourceSchema.
Related registration gaps (verified):
docs/schemas/trace-export.v2.schema.jsonwasn't regenerated. Runningpackages/control-plane/scripts/generate-trace-export-schema.mjsadds"discord-bot"(twice) and"discord". Nothing in CI checks it, so it drifts silently.control-plane/src/authorization/service-permissions.test.ts("does not grant bulk export to bot services") andshared/src/service-auth.test.ts(isServiceName) hard-code the older bot names. Runtime behavior for discord-bot is correct (verified), so this is a coverage gap: loop overSERVICE_NAMESinstead.

[Automated Review] A second, weaker tool-call → status-line formatter.
describeStep builds on summarizeToolCall + a local shortenPaths, while Slack already has a fuller formatToolStatus/compactPathPart in slack-bot/src/activity-status.ts. Verified differences with a probe:
glob→Used glob(Slack:Finding **/*.ts);list→Used listread /workspace/background-agents/README.md→Read …/background-agents/README.md(Slack strips/workspace/<repo>/→README.md)
Moving only toolCallFilePath to shared is a half-step. Suggest lifting the tool-name switch + path compaction into @open-inspect/shared and leaving each bot only its length limits/markup.

There was a problem hiding this comment.
[Automated Review] Harness is configured through Terraform, a new pattern for the bots.
GitHub and Linear resolve harness via /integration-settings (getValidHarnessOrDefault, linear-bot/src/utils/integration-config.ts with DEFAULT_HARNESS); Slack uses the default. Discord instead reads a HARNESS binding from Terraform and runs harnessIdSchema.parse on every task, so a bad value surfaces only as a generic per-task failure. The Terraform validation (contains(["claude","opencode"], …) plus the Anthropic-only pairing rule) also hand-copies HARNESS_CATALOG, and the defaults are restated in terraform.yml, variables.tf, terraform.tfvars.example and test-helpers.ts.
Please either move this to a discord integration-settings entry, or call it out explicitly as a v1 shortcut and validate once at startup instead of per request.

[Automated Review] A team_required refusal reaches the user only as an opaque trace ID.
Discord always creates sessions with teamId: null, so in a workspace with requireTeamOnCreate the control plane returns 400 team_required. Verified with a probe: the user-facing reply is only ⚠️ Couldn't start the task. Trace ID: …. The limitation is documented in DISCORD.md, but the bot knows exactly why it failed. Suggest mapping code: "team_required" to a TaskRejected with a clear message (e.g. "This workspace requires a team, which Discord tasks can't set yet").

[Automated Review] Callback routes are thinner than the sibling bots'.
- Missing secret: verified with a probe that with
SERVICE_AUTH_SECRETunset,/callbacks/completereturns 401unauthorized, so a deployment misconfiguration looks like a forged request. Linear returns 500not configured(linear-bot/src/callbacks/reject-invalid-callback.ts:21-32), and Slack has a test for it. - No
x-trace-idpickup and nohttp.requestlog withduration_ms, which Slack and Linear emit. - No
callbacks.test.ts(bad signature, bad payload, missing secret); Slack and Linear both have one. rejectInvalidCallbackalready exists separately in slack-bot and linear-bot. Rather than add a third variant, consider lifting it into@open-inspect/sharedand using it here.

[Automated Review] Requesting changes, but this is close: nearly every prior ask is resolved, and what's left is small.
Re-reviewed at c8a47c8d against the 2026-10-24 review. The follow-up commits addressed the integration-seam feedback thoroughly:
- The route table owns its gate, denial and legacy args.
- Discord has a named gate with its own reason codes and a coordinates-only
publication_stoppedcallback. - The registration lists are consolidated or made exhaustive (
Record<ServiceName, …>). - The bot reuses the shared tool-status formatter,
createKvCacheStoreand the shared callback-auth helper.
Thank you.
⚠️ Rebase needed
A trial git merge origin/main (main @ b1d915c8) conflicts in one file:
docs/GETTING_STARTED.md: the GitHub Actions settings table (~L1445). Main widened the table and added rows. Take main's table, re-add the 5 Discord rows (ENABLE_DISCORD_BOT…DISCORD_ALLOWED_ROLE_IDS), then runnpm run format.
About 30 other files merge cleanly but were changed on both sides. Please re-run typecheck and tests after rebasing. The likeliest to need a look:

Prior asks
| # | Ask | Status |
|---|---|---|
| 1 | Route table owns post gate + denial | ✅ Resolved. callback-routes.ts is keyed on MessageSource and carries postGate, denial and defaultArgs. Discord has teamlessPublicationGate with its own reason codes, the scope dependency is renamed to publicationScope, and Discord gets a publication_stopped callback so the status message no longer sticks on "Working…". The service file is down to 857 lines. |
| 2 | Registration gaps | ✅ Resolved. spawnSourceSchema is now a leaf module used by teams.ts and session-init.handler.ts. The trace schema is regenerated, with a --check step in CI. SERVICE_TEAM_CATALOG_POLICY is a Record<ServiceName, …>, so the compiler flags the next bot. Tests loop over SERVICE_NAMES. Also added: coverage policy, baseline and workflow; the compose-smoke exclusion and its test; docs meta.json and discord.mdx; bot_default_model.tftest.hcl. |
| 3a | Shared tool-status formatter / URL bug | ✅ Resolved. shared/completion/tool-status.ts is used by Slack and Discord, and URLs and shell arguments are no longer path-rewritten. |
| 3b | _MS durations + createKvCacheStore |
✅ Resolved |
| 3c | Thread-session store module | ✅ Resolved |
| 3d | Callback route hardening + tests | ✅ Resolved. A missing secret returns 500, x-trace-id is picked up, http.request is logged with duration_ms, and callbacks.test.ts is added. The shared getCallbackAuthRejection is adopted by all three bots. |
| 3e | team_required messaging |
✅ Resolved |
| 3f | Harness config | ✅ Resolved via the "v1 shortcut" option. launch-config.ts validates once per bindings object, checks against the shared catalog, and returns an actionable LaunchConfigError. Terraform still hand-copies the harness list and the Anthropic pairing rule, but the comments say so. |
| 4 | Minor cleanups | ✅ Resolved |
Required before merge

Non-blocking (inline)
- Give each route a typed

callbackContextwhenbody.sourcematches the calling service (callback-signing.ts:12). - Validate Discord IDs as snowflakes in the shared context schema (
session-api.ts:162).
Minor, not inlined:
scripts/terraform-discord-defaults.shis a Discord-named shim that the generic plan/apply steps now source. Avoiding restated defaults is the right goal, but this adds a second convention next to the inline|| 'default'the other bots use. Either make it generic (take the variable names as arguments) or follow the existing convention..github/workflows/coverage.ymlhas ~40 lines of unrelated line-wrapping churn. Please revert it to keep this 132-file diff focused.summarizeToolCall(extractor.ts, past tense) andformatToolStatus(tool-status.ts, present tense) are still two tool-name switches side by side. A follow-up could share oneclassifyToolCall(tool, args)with two renderers.
Security assessment
- Discord request signatures: ✅
- Ed25519 is verified via WebCrypto over the raw
timestamp + body, before any parsing. - Malformed hex, wrong key or signature lengths, and timestamps more than 5 minutes off are rejected.
- PING is answered only after verification.
- KV replay dedupe is best-effort, and documented as non-atomic.
- Ed25519 is verified via WebCrypto over the raw
- Role and channel restrictions: ✅
- An empty role list fails closed.
- The channel allow-list also covers threads under those channels, via
channel.parent_id. - Autocomplete returns no repositories to disallowed users.
- Role IDs are global snowflakes, so the role gate also pins the guild. An explicit
guild_idcheck against a configured guild would be cheap extra defense.
- DM rejection: ✅
isGuildCommandrequiresguild_id,channel_idandmember, and DMs get an ephemeral refusal (tested). - Terraform secrets: ✅
discord_bot_tokenissensitiveand bound as a worker secret.- A per-service
random_passwordgoes to both the bot (SERVICE_AUTH_SECRET) and the CP (SERVICE_AUTH_SECRET_DISCORD_BOT), and to the AWS secret list. - The public key and application ID are plain text and format-validated.
- Nothing sensitive is in outputs.
- Callback authentication: ✅
- The HMAC is checked on the original object before the strict schema parse.
- A missing secret returns 500; a bad signature returns 401.
- Strict schemas keep the callback kinds apart, so a signed payload for one route can't be replayed on another.
publication_stoppedcarries coordinates only and has a freshness window.
- Permissions: the
discord-botceiling is repo read/use plus session create/read/collaborate, with no export. Role holders are auto-enrolled as workspace Members, whichaccess.tsandDISCORD.mdcall out clearly. - Gaps: the read-time publication check (required item 2), plus the two defense-in-depth items above (source-to-service binding, snowflake IDs).

[Automated Review] The completion read isn't held to Discord's publication rule, so a session moved to a team can still be posted.
The control plane checks teamlessPublicationGate once, right before it sends /callbacks/complete. The bot then reads the session's events and artifacts here as an actorless discord-bot, with no channel scope and no read purpose. For that kind of read, admission only refuses private sessions:
control-plane/src/routing/route-admission.ts:641-665setsserviceReadPurposeonly forslack-bot.control-plane/src/authorization/session-admission.ts:94-97applies the publication gate only for"slack-post".shared/src/types/session-access.ts:196-200(checkServiceSessionAccess) lets a service viewer withteamId: nullread team-ownedworkspaceandteamsessions.
So if the session is moved to a team between the CP's gate check and this read, its summary and PR link still go to a public Discord channel. DISCORD.md L53-55 says the opposite: "If someone makes the session private or moves it to a team, the bot stops publishing session content". The window is short, but Slack closes the same gap with readPurpose: "slack-post" (slack-bot/src/completion/extractor.ts:32), which re-runs slackPostGate at read time. Tool-call callbacks are fine: they carry args directly and are gated on every call.
Suggestion: generalize the read purpose instead of adding a second one-off.
- Turn
serviceReadPurposeinto a publication purpose, e.g.purpose=publish. - In
evaluateSessionAdmission, look up the calling service's gate instead of hard-codingslackPostGate. That'steamlessPublicationGatefordiscord-bot, the same rule as itsCALLBACK_ROUTESentry. - Pass
readPurposehere. - Add an integration test: a
discord-botevents read with the purpose, against a team-owned workspace session, returns 404.
If you'd rather keep this PR's scope as is, narrow the DISCORD.md wording to what is enforced today (progress updates stop; a completion already in flight may still post), and we'll track the read-side gate as a follow-up. Please say in your reply which you choose.

[Automated Review] This pushes variables.tf past 1k lines: 920 → 1026 here, and about 1,067 once rebased onto main's 961.
The Discord block (L341-446) is self-contained. Please move it to terraform/environments/production/variables-discord.tf. Terraform loads every *.tf file in the directory, so nothing else changes, and discord_bot.tftest.hcl / bot_default_model.tftest.hcl keep working as they are. Moving it also takes these lines out of the rebase overlap with main's edits to this file.

[Automated Review] Nice: the route table now owns the gate, denial and legacy args, which resolves the previous ask. One more step would remove the hand-written context guards. (non-blocking)
postGate and denial.notification both take context: unknown, so each route re-checks the shape by hand:
- Slack's gate (L53) and denial (L65-71) use
isRecord+typeofchecks. - Discord's denial (L107-121) picks fields off an untyped record and then
safeParses them.
For Discord, the context has already passed discordCompletionCallbackPayloadSchema / discordToolCallCallbackPayloadSchema before the gate runs.
Suggestion: give each route a contextSchema and parse once in the service. For Slack, use a minimal loose { channel, threadTs? } so its legacy contract doesn't tighten. postGate and notification then receive typed context, and:
- the
isRecordguards disappear; - this file and
callback-notification-service.tsstop carrying twoisRecordhelpers that treat arrays differently (L44 here vs. service L72); - the Discord denial becomes a plain object literal.
While you're here: the service's private resolveCallbackRoute() (callback-notification-service.ts:215) wraps this module's resolveCallbackRoute() but returns a different shape. Renaming it (e.g. resolveDelivery) avoids the shadowing.
Fine as a follow-up.

[Automated Review] Optional hardening: adding discord-bot here lets it attach a callback context for any source, not just discord. (non-blocking; the same gap already exists between Slack and Linear)
mayAttachCallbackContext (routing/identity-enforcement.ts:205) only checks that the caller is in this list, and handleSessionPrompt uses body.source as sent. So:
- A
discord-botprompt withsource: "slack"and a Slack context makes the CP sign a callback with the Slack secret and deliver it toSLACK_BOT. - A
slack-botprompt withsource: "discord"makes the Discord bot post, with its bot token, to whateverchannelIdthe context names.
Now that the route table carries destination, this is a one-line check in session-prompt.ts: accept callbackContext only when, for example, resolveCallbackRoute(body.source ?? null).destination === ctx.principal.service. A leaked secret for one bot then can't drive another bot's outbound channel. Happy to take this as a follow-up.

[Automated Review] Validate the Discord IDs as snowflakes. (non-blocking, defense in depth)
channelId, threadId, statusMessage.id and userId are only checked as non-empty strings. The bot puts them straight into REST paths that it calls with its bot token (/channels/${channelId}/messages/${messageId} in discord-api.ts) and into <@${userId}> mentions.
Today only the bot itself produces these values. But this schema is also what the CP accepts and signs (see the callback-signing.ts comment), and fetch normalizes a value like 123/../../guilds/… into a different Discord endpoint. A shared discordSnowflakeSchema = z.string().regex(/^\d{17,20}$/) used for these four fields costs nothing and closes that. Terraform already uses the same pattern for discord_application_id.
Summary
This adds discord bot support. It closes the loop on the fixes and feedback from #2045 which appears to have stalled after receiving feedback.
