Peer comms approval gate + async delegate_bot (fixes on top of #128) - #129
Conversation
Bots could already consult each other synchronously via ask_bot; this adds the two missing pieces of peer collaboration: - delegate_bot: fire-and-forget handoff — the target bot picks the work up after the source turn settles, no blocking, same mirrored channel and chips for visibility - approvePeerComms: per-bot opt-in gate that turns any peer contact into an Allow/Deny/Always-allow card answered by the human first Also fixes PATCH /api/bots/:id silently dropping approvePeerComms.
… merge Merges #128 (thanks @stephenlzc) with the fixes it needs to be safe. The design is right — the depth cap still holds, a denied ask_bot doesn't hang the caller, and async handoff never regains agents tools — but three defects would have bitten users, and two of them were found by reproducing them, not by reading. 1. The approval card was never settled. `resolvePeerComms` took an ApprovalBus it never used (`_bus`), and a harness-native card emits no `request.resolved`, so `answered`/`dismissed` stayed unset forever. The client keeps rendering an unanswered card and the composer is disabled behind it — so turning the toggle on and using it once left that bot's chat permanently unusable, and the card is persisted, so a restart didn't clear it. Cards now settle on answer AND on timeout, stale cards from a dead process are dismissed at boot, and deleting a bot cancels approvals naming it instead of making the caller wait out 15 minutes. 2. The drained delegation ran as an uncaught `void startTurn(...)`. startTurn rejects on ordinary conditions — busy target, deleted bot, unavailable provider — and an unhandled rejection is fatal on Node 24, which in the packaged app kills the harness child. Failures now land as a chip on the source thread. 3. Async removed the backpressure ask_bot got for free by making the caller wait, with nothing in its place. Queues are capped per turn, a failed or interrupted turn drops its queue (with a chip) instead of firing it later on an unrelated turn, and the busy check is re-taken after the approval await — a 15-minute-old snapshot must not start a turn on a bot that is now mid-turn, or mirror a "Messaged @x" chip for an exchange that never happens. Also: an unresolvable `fromBotId` was the cheapest way past the gate — it skipped approval AND mirroring while still running the peer turn — so it is now a 403; the channel and chips are created after the verdict, not before, so a denial leaves no trace of an exchange that didn't happen; and the tool's refusals say what to do instead of returning a bare enum. Tests: new server/peer-approval.test.ts pins the lifecycle (verified it fails without the settle fix). Suite 374 passed / 8 skipped. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The comment contradicts the code.
Line 529 states "Both bots run ask-peer". Line 532 assigns askerSelection to the askerDelegate instance, which runs FAKE_ACP_MODE=delegate-peer. Only Helper runs ask-peer. The regression signal the test describes still holds, because B is the bot that would recurse, but the comment misstates the setup.

waitFor returns immediately for boolean predicates.
The loop exits when v !== undefined. Callers at lines 168, 198, 251, and 287 pass predicates that return runTargetCalls.length === 1, which evaluates to false before the delegation lands. false !== undefined is true, so waitFor resolves on the first check and does not wait. Those tests currently pass only because await yields one microtask, which happens to be enough for the synchronous drain path. Any added await inside processOne breaks them.
Treat a falsy result as "not ready".

Attach a rejection handler to the fire-and-forget processOne call.
void processOne(...) discards the promise without a catch. processOne performs store writes, broadcasts, and an awaited approval. Any throw inside it becomes an unhandled rejection, which terminates the Node process by default. server/index.ts guards startTurn for exactly this reason at lines 476-491; the drain loop needs the same protection.

The throw propagates out of callTool, so line 113 never runs and the agent receives a JSON-RPC error instead of the guidance string, for example "delegation chains are limited to one hop — do this one yourself".
/api/internal/ask-bot already handles the equivalent case with 200 plus an error field at server/index.ts line 1196. Align the delegation endpoint with that pattern.

The post-approval re-check does not handle a deleted target.
Line 1223 reads store.bot(toBotId)?.busy. If the user deletes the target while the card is open, store.bot(toBotId) is null, ?.busy is undefined, and the handler continues with the stale target record. getOrCreateChannel and mirrorExchange then append messages to the deleted bot's thread, which recreates the transcript file that Store.deleteBot just unlinked. processOne in server/delegations.ts handles this case correctly at lines 148-150.

Pass the source thread ID to /api/internal/delegate-bot.
RoutineManager creates detached tasks with createTask(..., false), while startTurn(..., { threadId: task.threadId }) emits turn.completed for that detached thread. The proxy sends only fromBotId, so queueDelegation uses the bot's active thread instead. drainDelegations and discardDelegations then miss the queued delegation. Include the calling thread ID in the proxy request, endpoint body, and queue key.

Stale-card cleanup skips every non-active task thread.
dismissStalePeerCards scans only bot.threadId, which is the active task's thread. A bot can own several task threads (bot.tasks). A peer card left in a background task thread is never settled at boot. The user switches back to that task and the composer stays disabled behind an unanswerable card — the exact failure this function prevents.

Merges #128 by @stephenlzc with the fixes it needs. The design is right — I verified the depth cap still holds (
MAX_COMMS_DEPTH=1, comms-invoked turns get no agents tools, so async does not re-open the recursion the cap closed), a deniedask_botdoesn't hang the caller, and group turns can't launder depth through theA ⇄ Broom.Three defects would have bitten users. Two were reproduced, not just read.
1. The approval card was never settled — this bricked the thread
resolvePeerCommstook anApprovalBusit never used (the parameter is literally_bus), and a harness-native card emits norequest.resolved, soanswered/dismissedstayed unset forever.PendingApprovalkeeps matching the unanswered card andComposerdisables input behind it — turn the toggle on, use it once, and that bot's chat is permanently unusable. The card is persisted, so restarting didn't clear it; after the 15-minute timeout, Allow/Deny fell through to the provider adapter and threwno such pending request, leaving no way to dismiss it at all.Now: cards settle on answer and on timeout; stale cards from a dead process are dismissed at boot; deleting a bot cancels approvals naming it rather than making the caller wait out the timeout; the timer is
unref'd so a waiting card can't hold the process open.2. An ordinary delegation failure killed the harness process
The drain ran
void startTurn(...)with no.catch— the only unguardedstartTurncall site. It rejects on busy target, deleted bot, and unavailable provider, and an unhandled rejection is fatal on Node 24, which in the packaged app takes down the server child. Failures now land as a chip on the source thread.3. Async removed backpressure with nothing in its place
ask_botgot backpressure for free by making the caller wait. Fire-and-forget doesn't. Added: a per-turn queue cap; a failed or interrupted turn drops its queue with a chip (previously it survived and fired later on an unrelated turn — not what someone who hit Stop expects); and the target'sbusycheck is re-taken after the approval await, since a 15-minute-old snapshot must not start a turn on a bot that's now mid-turn, or mirror a "Messaged @x" chip for an exchange that never happens.Also
fromBotIdwas the cheapest way past the gate — it skipped approval and all mirroring while still running the peer turn. Now a 403, so every peer turn has an accountable sender."delegation chains are limited to one hop — do this one yourself") instead of returning a baretoo_deep.broadcastsignature to match main's resumable-stream work (this was the only real merge conflict).Verification
server/peer-approval.test.ts(new) pins the card lifecycle — settle on allow/deny, cancel-on-delete, boot sweep idempotence. Confirmed the tests fail without the settle fix (2 fail, 4 pass) and pass with it.Known follow-up (not blocking)
The delegated turn's reply isn't mirrored back into the
A ⇄ Bchannel —mirrorReplyis only called on theask_botpath — so the channel is complete for asks but request-only for delegations. Worth a follow-up: prior art (A2A, MCP Tasks, buzz) is unanimous that every terminal state of an async handoff should be visible where the human is looking.🤖 Generated with Claude Code
