Clear the stale Needs input badge when Claude's permission is decided in the terminal - #15170
Conversation
Claude Code runs its PermissionRequest hook beside its own permission dialog and auto-mode classifier. When either decides first, Claude keeps the abandoned hook waiting until the hook's own timeout, so the Feed request and its "Needs input" sidebar overlay stay up next to "Running". This test fails until a later hook from the same agent retires it. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Claude Code runs its PermissionRequest hook beside its own permission dialog and auto-mode classifier and never cancels it when either one decides first. The `cmux hooks feed` process kept waiting on feed.push until its ~115 s timeout, and the Feed-owned "Needs input" overlay (cmux.feed.attention:claude_code) stayed next to the agent's own "Running" status for that whole time. The hook CLI now stamps each Feed frame with its send time and subagent identity. A blocking request is stamped only after its ordering barrier delivered every earlier hook, which includes the tool's own PreToolUse. When a later-stamped PreToolUse, PostToolUse, UserPromptSubmit, Stop, or SessionEnd from the same Claude session and agent arrives, Feed retires the request: the hook returns no decision, the card expires, and the overlay and banner clear.

Use a strictly increasing hook-order value.
FeedWaiterRegistry.supersede(by:) retires a request only when requestedAtMs < observedAtMs. Both values use millisecond wall-clock timestamps, so sends within one millisecond can compare equal. A later Claude event can then fail to retire the request, leaving its attention state pending until timeout.
Use a strictly increasing sequence, or another ordering value that guarantees a later send compares greater than the request stamp.

Remove the wall-clock assertion on _hook_sent_at_ms.
Line 119 reads Date(). Line 140 then asserts sentAtMs >= startedAtMs. The test guidelines ban reading Date() in an assertion. The comparison also mixes two clocks: the CLI process clock and the test clock. An NTP step between the two reads makes a correct build fail. Assert on presence and a positive value instead.
Proposed fix
- let startedAtMs = Int64(Date().timeIntervalSince1970 * 1000)
...
- #expect(sentAtMs >= startedAtMs, "event=\(event)")
+ #expect(sentAtMs > 0, "event=\(event)")As per coding guidelines: "Reading Date() / Date.now / ... in an assertion."

Remove the elapsed-duration assertion.
Line 842 asserts startedAt.duration(to: .now) < .seconds(4). The test guidelines ban assertions on a measured wall-clock duration. The done wait with a deadline and the .unavailable result already prove that supersession happened before the 5-second timeout. A timeout would return .timedOut, not .unavailable.
Proposed fix

Problem
The sidebar showed "Needs input" (bell) next to "Running" (bolt) while Claude Code was visibly working. It was most common in auto mode and whenever a permission prompt was answered in the terminal.
The stale entry is the Feed-owned overlay (
cmux.feed.attention:claude_code), not the agent'sclaude_codestatus. The two keys render side by side. Event log from a live repro (session c4cf405a, cmux NIGHTLY):Root cause: Claude Code runs the PermissionRequest hook in parallel with its own dialog and auto-mode classifier. It passes only the tool-use abort signal and ignores its "already decided" callback, so the hook is never cancelled when the user answers in the terminal or the classifier decides. The
hooks feedprocess keeps waiting until its timeout.FeedCoordinatorconcludes the overlay only on a Feed reply, a timeout, or journal invalidation, so the overlay outlives the decision by up to about two minutes.Fix
_hook_sent_at_msand the subagentagent_id(sendFeedTelemetry). An actionable request is stamped only afterwaitForPriorAgentHookDeliveriessucceeds (runFeedHook). By then every hook the agent published earlier, including the tool's own PreToolUse, has already been sent.FeedCoordinator.retirePendingDecisionsSuperseded(by:)runs on each accepted Feed event. It handles a Claude PreToolUse (excluding AskUserQuestion/ExitPlanMode), PostToolUse, PostToolUseFailure, UserPromptSubmit, Stop, or SessionEnd that was stamped after a pending request from the same session and agent. Such an event proves the decision was made elsewhere, soFeedWaiterRegistry.supersede(by:)retires the request. The hook then returns no decision, the card expires, the overlay concludes, and the banner and semantic notification clear. The journal also records the resolution, the same way a Feed reply does.Tests
FeedCoordinatorTests.laterClaudeHookRetiresPermissionDecidedOutsideFeedis the behavior-level regression. Earlier and subagent hooks leave the request live, and a later main-agent PreToolUse releases the blocked hook with no decision and expires the card. Commit 1 adds only this test, so CI should be red there.FeedWaiterRegistryTests: ordering, session, source, and subagent scoping, plus unstamped requests.ClaudeHookFeedTelemetrySwiftTests.feedTelemetryCarriesSendStampAndAgentIdentity: the CLI stamps telemetry frames.Localization: no user-facing strings added or changed.

Summary by cubic
Fixes the stale "Needs input" sidebar badge that appeared next to "Running" when a Claude permission prompt was answered in the terminal or auto-mode decided. The abandoned PermissionRequest hook kept the Feed-owned overlay up for up to two minutes.
Now, a later-stamped tool, prompt, or stop hook from the same Claude session and agent retires the blocking request: the hook returns no decision, the card expires, and the overlay and banner clear.
Written for commit 6790398. Summary will update on new commits.
