What

With live relay on, a pod's agent messages now go out to the pod's bound Discord channel, the way Telegram and Slack already work. Mirror sends every agent line, attention sends only the addressed ones, and mute holds them. Discord is the third outbound ChatRelayAdapter (D249, after #3456 inbound).

How

• Sending. It uses the channel webhook the install already stores encrypted (webhookUrlRef, with ?wait=true). The URL has to match Discord's webhook pattern before anything is sent, and no bot token is used.
• Mentions. Every send carries allowed_mentions: { parse: [] }. @everyone and @here are defused and names are markdown-escaped, so an agent can't ping the server.
• Length. Lines read [Pod] **Agent**: text and are cut at 2000 characters without breaking an emoji. They are truncated, not split, as on Telegram and Slack.
• Rate limit. Each webhook gets one queue per replica, with sends at least 400 ms apart.
  • A short 429 gets one retry after retry_after.
  • A longer one starts a cooldown. Lines that arrive during it are dropped with a log line, and they stay in the pod.
• Failures. Codes 10003, 10015, 50001 and 50013 put the row into error with a reason a person can read. A 429 or 5xx never changes the row's status.
• The core stays generic. Each adapter declares directRows, and the dispatcher selects chatRelayDirectRowTypes(), so no platform is named there. Telegram dispatches as before.
• Who can turn it on. The rule from feat(discord): a bound channel relays its installer's messages live into the pod #3456 still applies: the row's creator, with a proven discordUserId. The send path checks linkedUserId === createdBy again.
• Connectors. A proven Discord row gets Manage, the Relay switch and Attention/Mirror, shown only to the creator. An unproven row says to add the bot again. The copy says the whole server can read the channel. Strings are in en and zh-CN.
• Gateway pre-filter. A cached discordUserId skips the per-line row read for every author except the installer.

Tests

• Written first, failing before the change: the new discordBridgeService.outbound.test.js, plus new cases in installableEventHandlers, connectorDeliveryFailureService, discordBridgeService and ConnectorsPage.channels.
• Telegram, Slack, decision cards and the bind rule: their suites pass unedited. Three assertions in chatRelayCore.test.js changed, because they asserted that outbound relay was Telegram and Slack only.
• Reverse checks:
  • dropping allowed_mentions fails the no-ping and decision-card tests;
  • dropping the mode filter fails the attention-mode test;
  • offering the switch on an unproven row fails the "no relay switch" test.
• Typecheck: backend and frontend tsc are clean.

Not covered

• No screenshots yet; the app wasn't run.
• Follow-ups:
  • a Discord row in error has no reconnect button (this predates this PR);
  • after a 10015 the bot has to be added again.

Walkthrough

Discord now supports outbound chat relay through the shared adapter registry. The change adds webhook delivery, identity and pod-membership checks, delivery-failure handling, and creator-gated relay controls in the connector interface.

Permanent Discord failures mark the matching row while retaining channelId. The tests and contract cover these behaviors.
Connector relay controls frontend/src/v2/connectors/channelModel.ts, frontend/src/v2/connectors/ChannelPanel.tsx, frontend/src/v2/connectors/useChannelConnectors.ts, frontend/src/i18n/locales/en.json, frontend/src/i18n/locales/zh-CN.json, frontend/src/v2/__tests__/ConnectorsPage.channels.test.tsx	Discord relay controls require creator identity and a proven Discord ID. The interface shows Discord-specific relay descriptions and bot-reinstallation guidance. English and Chinese strings and UI tests are added.

Merge Risk: Low · up to 7721b

Discord outbound relay now covers mirror and attention modes, with identity checks and a bounded send queue. A disconnected Discord row can still relay the installer's inbound messages into the pod, and a send already queued can post after disconnect if webhook deletion failed. The author reports that several earlier review concerns are already fixed. Both open issues are bounded, and the inbound one predates this PR, so address them before merge or soon after.

Explanation

The title names the main change: Discord agent lines now relay to the pod's bound Discord channel, with delivery depending on mode. It matches the changeset, which adds Discord as an outbound ChatRelayAdapter with mirror and attention modes. The title is long at 88 characters, but it stays specific and on topic.

Full details: Description check

Explanation

The description states the purpose: agent messages now go to the bound Discord channel through the stored webhook, with mirror, attention, and mute modes. It also covers the mention handling, length limits, rate limiting, failure codes, creator-only enablement, connector UI, tests, and follow-ups. These match the changeset files, which add the Discord outbound adapter, delivery-failure classification, gateway pre-filter, and connector controls.

HEAD: 408aaa6 — GATE: PASS

One review (Opus), read in code: PASS. The new test files weren't run locally (no ts-jest in a local checkout); CI covers them.

Verified

• Who can send. Only a Discord row with live relay on and a proven discordUserId, whose creator is its linked user. The key fields are server-owned. The PATCH runs through liveRelayRefusalFor. F143 and F90 are unchanged.
• Webhook URL. It comes from the encrypted ref, or from server-owned fallbacks, and is checked against an anchored Discord-host pattern. No log prints it.
• Mentions. There is one send path, with allowed_mentions: { parse: [] }. @everyone and @here are defused before truncation.
• Rate limiting. One short retry on a 429; longer waits cool down and expire on their own.
• Generic core. Telegram and Slack dispatch is unchanged, and the edited assertions only add discord.
• Classifier. Only 10003, 10015, 50001 and 50013 flip a row; 429 and 5xx never do.
• Echo. The webhook's own copy is dropped in both the gateway and the bridge.
• Strings. en and zh-CN follow the glossary.

Being fixed in a push on this PR (none of these blocks the merge):

• Medium: the relay keeps sending after the installer leaves the pod, and a guild channel is shared.
• Low: the "add the bot again" note shows to viewers who aren't the creator, and the toggle shows to admins who aren't the creator.
• Low: a 401 with code 50027 (revoked webhook token) never marks the row.
• Low: [, ] and ( in a pod or agent name can form a link.
• Low: the send queue has no cap.

GATE: PASS

In attention mode, shouldEscalate also sends every message from the configured lead agent. This row label says only escalations reach the channel.

Add webhook allowlist cases that reflect the real bypass shapes.

The only negative case is https://example.com/collect. The allowlist regex is the single control that stops agent text going to an attacker-chosen URL, because config.webhookUrl is a legacy field that may have come from a request body. A test with one obviously foreign host would still pass if the regex lost its anchors or its host escape.

Add test.each cases for:

• http://discord.com/api/webhooks/1/x
• https://discord.com.evil.example/api/webhooks/1/x
• https://discord.com@evil.example/api/webhooks/1/x

Bound the per-webhook lane queue.

Each call chains onto current.tail. Only a 429 cooldown drops lines. If Discord returns 5xx or hangs, each queued send can take up to the 10 s axios timeout. The sends run serially. relayAgentMessageThroughAdapter awaits adapter.send, so every waiting caller stays pending. In mirror mode with a chatty pod, the backlog grows without limit. Lines then reach the channel minutes late, out of context.

Track a pending count on the lane. When the count exceeds a small cap, return a dropped result immediately and log it. The doc already presents "dropped and logged" as the designed under-delivery behavior. Extend it to this case, and add a test for it.

Test identity propagation through the cache refresh.

The current tests provide discordUserId directly and mock ensureChannelCache(). Add a test that calls the real ensureChannelCache() and uses an Integration.find(...).select(...).lean() chain whose projection omits config.discordUserId when that field is not selected. Then relay a proven author’s message and assert that the relay succeeds. The test must fail if the projection drops config.discordUserId.

@coderabbitai, on the body points from your review at 408aaa6 (all in 7721bed unless noted):

• Attention label: fixed. en and zh-CN now say the lead agent's lines also reach the channel. The row mark has no renderer on the v2 page, so the assertion checks both locale files.
• INTEGRATION_CONTRACT.md:176: fixed. Outbound runs on the server through the stored config.webhookUrlRef, with no bot token. 50027 is listed too.
• ChannelVerdict: fixed. 'discord' is in CHANNEL_VERDICT_PROVIDERS, with a test that creates, reads back and validates a Discord verdict.
• Allowlist negatives: added the five bypass shapes plus a foreign host as a test.each, each asserting that nothing is sent.
• Lane queue bound: covered in e74ab43. The queue holds at most 20 lines, the hanging send included, and the rest are dropped and logged. The test uses a hanging post.
• Cache-refresh identity: added. The real ensureChannelCache runs against a projection-honouring find(), and the test fails if config.discordUserId is dropped from the projection.

Review comments at @backend/services/discordBridgeService.ts:
- Line 108: Update the inbound relay guard that checks integration.status so it
accepts messages only when the status is connected, preventing relay after
disconnect; add a gateway-path test confirming messages are not written to the
pod after disconnect.

Other comments:
Review comments at @backend/services/discordBridgeService.ts:
- Line 282: Recheck the integration status in sendThroughLane immediately before
each postToWebhook call, including after a 429 retry delay, and stop the send if
the integration is disconnected. Alternatively, cancel queued sends when
DiscordService.disconnect() starts, ensuring no queued or retrying send posts
after disconnect.

@lilyshen0722 Thanks. Source inspection confirms all six reported follow-ups:

• Both attention labels include the lead agent, with assertions for both locales.
• The contract documents server-side delivery through config.webhookUrlRef, no outbound bot token, and error 50027.
• ChannelVerdict accepts Discord, with create/read/validate coverage.
• All six invalid webhook URL cases assert no send.
• The queue-bound test uses a hanging send and checks that excess lines are dropped and logged. The configured limit is 20, including the in-flight send.
• The cache-refresh test uses the real refresh and a projection-honoring mock to protect config.discordUserId.

These changes address the six body points. I inspected the source and test assertions; I did not run the tests.
