Answer approvals with a typed outcome, and notice a bot repeating itself

[aivsomkar]

In plain language

Two small things about bots asking permission and bots getting stuck.

1. Answering an approval that's already gone no longer breaks (2.5).
Bots ask you "Allow / Deny" before running commands. If you answered after the moment had passed — you'd pressed Stop, the ask had timed out, or the engine had no way to take an answer — the app used to throw an error and the card just sat there open.

• What changes: the card quietly settles as dismissed and a small note appears: "Couldn't deliver that answer — the request is no longer open, so the action was not run." Nothing runs without a real answer. That's the "fail-closed" part.
• Under the hood every engine now reports what actually happened to your answer (allowed once / rejected / answered / unavailable) instead of "ok or crash", and the record of who decided (you, auto mode, a timeout, the app) is accurate — Codex used to label everything "you", including timeouts.

2. The app tells you when a bot is repeating itself (2.8).
Nothing watched for a bot running the same command with the same arguments over and over — and that's your money.

• What changes: after the 5th identical call in one turn (and again at 10 and 20) a note appears in the chat: "Same call repeated 5× — Bash: git status — it may be stuck." It doesn't stop anything — you have the Stop button; this is the nudge. It only counts calls whose arguments it can see (approval cards always carry the command; some engines' event titles do), so five different commands never trigger it.

For the reviewer — where to look

• server/contracts.ts — RequestOutcome; respondToRequest returns it; request.resolved gets typed behavior and source (unavailable and peer added).
• Drivers — claude.ts (broker answer() false → unavailable, no more throw), codex.ts (missing ask → unavailable; finish now carries the real source), acp/core.ts (same), antigravity.ts / grok.ts / boxagent.ts (no asks → unavailable instead of throwing), testing/fake-driver.ts.
• server/index.ts — answerRequest() used by both /respond endpoints: on unavailable, settle the card (answered: "unavailable", dismissed), drop the chip, return 200 { outcome }; the auto-approve path branches on the outcome; the repeat-detector subscriber (kept out of the main fold like the delegation drain).
• server/repeat-detector.ts — pure; callKey normalizes whitespace and rejects a bare tool name; thresholds fire once each; reset on turn.completed.
• Kept on purpose: the timeout note text (it's guidance to the model after a typed deny) and request.opened's own tool/summary (the itemId-drift risk is theoretical; not worth touching every driver's event shape).

Items 2.5 and 2.8 of docs/plans/agent-harness-upgrades-v2.md. Adapter contract grows by one return type only — no new required methods, the one-file driver promise holds.

Test plan

• repeat-detector.test.ts (4): key normalization / bare-name rejection; thresholds once each; threads and calls kept apart; reset on settle
• claude.test.ts: happy path resolves allowed-once; unknown ask and unknown thread resolve unavailable (was: throws)
• antigravity.test.ts: no-channel driver resolves unavailable (was: throws)
• pnpm typecheck clean; pnpm vitest run green (65 files, 531 passed)
• Manual: POST /respond with a never-asked requestId → 200 {"outcome":"unavailable"} and the chip appears; a real ask → Allow → runs

Summary by CodeRabbit

• New Features

  • Added warnings when tools or permission requests repeat beyond configured thresholds.
  • Approval activity now records how requests were resolved, including user decisions, timeouts, and system actions.
  • Responses now provide clear outcomes for approved, rejected, answered, or unavailable requests.

• Bug Fixes

  • Unavailable or already-resolved permission requests no longer cause errors.
  • Unavailable auto-approval requests are safely dismissed and surfaced for human review instead of leaving approval cards open.

Warning

Review limit reached

@milind-soni, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 35 minutes

Limit details: You’ve used all 3 included reviews currently available under your plan.

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The change adds typed request outcomes and resolution sources across provider adapters. The server centralizes request responses and handles unavailable requests. A repeat detector reports repeated tool calls and permission requests at configured thresholds.

Changes

Request resolution and repetition handling

Layer / File(s)	Summary
Request outcome contracts server/contracts.ts	request.resolved events now use literal behavior and source unions. respondToRequest returns the exported RequestOutcome union.
Provider resolution behavior server/drivers/*, server/testing/fake-driver.ts, server/drivers/*.test.ts	Adapters record user, timeout, and system sources. Missing or unsupported requests return "unavailable". Tests verify unavailable and successful outcomes.
Server request response flow server/index.ts	answerRequest centralizes provider responses, dismisses unavailable approval cards, updates auto-approval fallback, and returns outcomes from bot and thread endpoints.
Repeated call detection server/repeat-detector.ts, server/repeat-detector.test.ts, server/index.ts	The server tracks normalized calls per thread and reports threshold crossings at 5, 10, and 20 calls. State resets when a turn settles.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 1c306

This change improves expired approvals and detects repeated calls, but approval results can still be recorded inconsistently for some engine paths, and connected clients may not see dismissed cards or warnings without reloading. The PR is not merge-ready until these bounded correctness and UI-update issues are addressed or explicitly accepted.

199-218: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Normalize answer for permission requests.

When behavior is "answer" and isQuestion is false, Lines 209-213 send a denial. Line 215 records "answer", and Line 476 returns "answered". The provider action and the reported outcome then disagree.

Make finish return the normalized behavior. Derive both request.resolved.behavior and RequestOutcome from that value. Alternatively, reject "answer" for permission requests before calling finish.

Also applies to: 474-476

- Around line 444-445: Update the permission-resolution handling around
createPermissionBroker.close and request.resolved so broker shutdowns produce a
supported source at runtime: map "shutdown" to "system" before emitting or
normalize it in the consumer. Do not rely on the existing source type cast,
which does not transform the value; preserve the existing user, timeout, and
system mappings.

In `@server/index.ts`:
- Around line 307-318: Update the unavailable-request handling in
server/index.ts lines 307-318 so the message produced by store.patchMessage and
the activity produced by store.appendMessage are each broadcast to connected SSE
clients immediately after their mutations. Also update the repeat-warning
activity flow at server/index.ts lines 662-666 to broadcast its
store.appendMessage result; use the existing broadcast mechanism and preserve
the current message contents and ordering.
