Add a Stop button over terminals while an agent turn runs - #15234
teamleaderleo wants to merge 31 commits into
Conversation
Behind the new agentActions.turnControl setting (off by default), a Stop pill appears in a terminal pane's bottom-trailing corner while Claude Code or Codex is running a turn there. Clicking it sends Escape through the same named-key path the TextBox uses, then journals the interrupt as a turn completion for the pane's active hook session: agents run no Stop hook when interrupted, so the pane would otherwise stay running. Part of #15223. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Review fixes for the Stop button: - The interrupt now settles every session the journal consumer has running on the surface (AgentLifecycleReducerState.userInterruptDrafts), instead of guessing the newest hook-store entry. A nested `claude -p` session or a relay session no longer gets a phantom idle session while the parent keeps running, and a click no longer parses the hook store on main. - Only Claude Code settles through the journal. Codex journals lifecycle at prompt submit and Stop only, so a settle could leave a still-working Codex pane idle for the rest of its turn. - Stop holds for 1.5 s after a click, so a double click sends one Escape (a second Escape at Claude's idle prompt opens its rewind menu). - The pill is raised above the find overlay whenever that overlay is. - tests/test_cmux_settings_supported_paths.py knows the agentActions section.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Bound the journal poll by a deadline, not an iteration count.
If the journal consumer runs slowly, 100 sleeps can finish before it records the interrupt. The test then fails even though the interrupt is recorded later. Keep the event predicate, but await a completion signal or poll it until a generous clock deadline. As per coding guidelines, a poll bounded by an iteration count rather than a deadline is not deterministic.
Proposed deadline-bound poll
- for _ in 0..<100 where interrupt == nil {
+ let clock = ContinuousClock()
+ let deadline = clock.now.advanced(by: .seconds(10))
+ while interrupt == nil && clock.now < deadline {
try await Task.sleep(for: .milliseconds(20))📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Keep synthetic interrupt timestamps in the session’s causal time domain.
AgentJournalStore.append stores occurredAtMs unchanged. userInterruptDrafts currently uses local Date(). Both AgentNotificationReconciler and AgentLifecycleReducer can then reject a later turnStarted whose relay timestamp is lower. The interrupt has already moved the session to idle, so the pane can remain idle after the agent resumes.
Set each generated interrupt draft to that session’s accepted lastOccurredAtMs, then add a regression test with a local-time interrupt followed by a later relay hook whose timestamp is lower than the local time but later than the accepted relay timestamp.

Route per-panel lifecycle updates through targeted refreshes.
Workspace.setAgentLifecycle mutates one panel at Sources/Workspace+AgentLifecycle.swift:499, but its computed setter scans every panel ID. The underlying setter already compares the complete maps, so this change adds another O(P) pass to each event.
DockSplitStore.setAgentLifecycle also mutates one panel at Sources/DockSplitStore+RestoredAgentLifecycle.swift:306-308. mutateAgentRuntime writes that panel back to agentRuntimeByPanelId, whose new observer scans every Dock panel. A sequence of P per-panel events can add O(P²) work.
Route ordinary lifecycle mutations through owner methods that refresh only the changed panel. Keep one full diff for bulk replacement, transfer, restore, or reset operations.

Make workspace.create retries idempotent.
openTerminal() reuses the top-level request ID, but the control-socket handler reads idempotency from params.operation_id. If the first request times out after v2WorkspaceCreate adds the workspace, the retry can create a second workspace. The test uses the second response and tearDown() terminates the app, so this does not by itself invalidate the assertions. It still leaves unintended duplicate state during the test.

Add a descriptionKey for turnControl using
schemaDescriptions.agentActions.turnControl, then add the matching localized
message to each of the 20 locale catalogs. Keep the localized text aligned with
the schema description’s behavior: the Stop button interrupts an active turn by
sending Escape and marks it stopped.

Add translations for every catalog locale.
sidebar.extensions.action.noSpaceForPane has translations for only 9 of the catalog’s 20 locales. The same gap affects cli.restore.notice.routedLauncherUnavailable, cli.focus.defaultHelp, cli.help.openFocusFlags, settings.app.compactAgentStatus and its subtitle, settings.search.alias.setting.app.compact-agent-status, sidebar.agentStatus.glyph.tooltip, and sidebar.compactStatus.profile.
Add translations for bs, da, it, km, nb, pl, pt-BR, ru, th, tr, and uk to each entry. As per coding guidelines, “additions include complete translations for all existing locale codes in the touched catalog.” The path instruction also requires production user-facing text across “every locale already supported by its catalog.”

Bound settlement reconciliation after startup replay failure.
When readPage fails, reduceStartupReplay returns nil, so the replay branch does not advance reconciledThroughSequence. A later .settleInterrupt then scans from sequence 0 through the journal head and calls reconcile(..., deliver: true) for every unreconciled row. Each row can perform MainActor.run work, which can stall the consumer and churn the main actor.
claimNotification durably rejects existing claims, so already-claimed notifications are not re-delivered. This does not remove the scan cost, and unclaimed historical notification rows can still enter the delivery path.
Bound the recovery scan to the sequence range needed for the captured live sessions instead of treating cursor 0 as a full-history settlement. Changing only deliver to false would not remove lifecycle application or notification-admission work.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Fix the claim that every click marks the turn stopped.
The description says one click sends Escape "and marks the turn stopped" for both Claude Code and Codex. AgentTurnInterruptTarget.settlesTurnInJournal is true only for .claudeCode (Sources/AgentTurnInterruptTarget.swift Line 35). interruptAgentTurn returns before recordUserInterrupt() for Codex (Sources/Panels/TerminalPanel+AgentTurnControl.swift Line 57). For Codex, the pane stays running until Codex emits its own hook. The schema and settings docs therefore promise behavior that does not occur for Codex.
Scope the second claim to Claude Code. Apply the same correction to the translated schemaDescriptions.agentActions.turnControl strings in every web/messages/*.json locale.
Proposed wording
- "turnControl": "Show a Stop button over a terminal while Claude Code or Codex is working on a turn. Clicking it sends Escape, the agent's own interrupt key, and marks the turn stopped."
+ "turnControl": "Show a Stop button over a terminal while Claude Code or Codex is working on a turn. Clicking it sends Escape, the agent's own interrupt key. For Claude Code, cmux also marks the turn stopped."📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Review: codex review found a P2 in AgentTurnInterruptTarget.resolve: an unsupported running agent such as OpenCode could be ignored, allowing Stop to target Claude without foreground proof. Fixed: resolution now treats every running lifecycle key as an ambiguity, requires explicit foreground ownership when multiple agents run, and returns only a supported target; added regression coverage for Claude plus OpenCode. Left: local CmuxAgentJournal package execution was unavailable because this Linux environment lacks the SQLite3 module; CI provides the native lane. The refreshed branch also retains main's Ghostty pin and normalized project file. |

Summary
First slice of #15223 (clickable agent actions). With Settings > Terminal > Agent Stop Button on (
agentActions.turnControl, off by default), a small Stop pill sits in a terminal pane's bottom-trailing corner while Claude Code or Codex is running a turn in that pane. Clicking it interrupts the turn.claude_codeorcodexisrunning, the same state the TextBox checks before it forwards Escape. Other agents get no button until their interrupt key is verified. Toggling the setting mid-turn shows or hides the pill at once; it listens for defaults changes only while an agent is running.TerminalPanel.sendNamedKeyResult, the named-key path the TextBox andmobile.chat.interruptalready use. The click is re-checked against the current lifecycle first, so a late click after the turn ended sends nothing.running: Claude Code runs no Stop hook when a turn is interrupted (Sidebar 'Running' status stays on after user interrupts an agent turn #4389), so the pane would keep showing Running and the button would stay up. After sending Escape, cmux asks the agent journal to settle every Claude session its own fold has running on that surface: each gets aturnCompletedevent (AgentJournalEventDraft.userInterrupt, native eventcmux.user_interrupt) with no notification, so no "done" alert fires. Settling from the fold rather than the hook store means nestedclaude -psessions and relayed sessions are handled correctly. If Claude keeps working, its next PreToolUse hook declares the pane running again. Codex is not settled this way: it journals lifecycle only at prompt submit and Stop, so a settle could leave a still-working Codex pane idle.TerminalAgentTurnControlView, an AppKit overlay mounted inGhosttySurfaceScrollViewbeside the password-input badge and raised above the find overlay. Only the button takes clicks; the rest of the overlay passes hit-testing through to the terminal. Workspace and Dock lifecycle writes both refresh it.agentActionssection in the catalog,cmux.json({"agentActions": {"turnControl": true}}), the schema, and settings search. Later categories from the RFC add one key each.Testing
swift test --package-path Packages/macOS/CmuxAgentJournal --filter AgentJournalUserInterruptTests(local, 3 passed): turnStarted, interrupt, turnStarted gives running, idle with no notification identity, then running, forclaudeandcodex; the fold's interrupt drafts cover only live running sessions on the surface (including a session without an id) and settle it to idle without touching another surface.swift test --package-path Packages/macOS/CmuxSettings --filter SettingCatalogTests(local, passed): the key defaults off and matches its section prefix.cmuxTests/TerminalAgentTurnControlTests.swift(added, runs in CI): the pill shows only while enabled and running, hides mid-turn when the setting turns off, stays hidden by default, two quick Stop clicks enqueue exactly one key event, and a click after the agent stopped enqueues none. A journal-center test checks thatrecordUserInterruptjournals the interrupt for the session the center has running on the surface.python3 tests/test_cmux_settings_supported_paths.py(local, passed).python3 scripts/verify-local.py: 15/15 selected checks passed (localization parity, xcstrings, schema, project and test wiring).scripts/ui-test AgentActionPillUITestsat 6c11b3e (run, both tests passed): with the setting on, journaling anagent.turn.startedfor a Claude Code session on a terminal over the socket shows the Stop pill; clicking it hides the pill, so the interrupt settled the turn. With the setting off, the same event shows no pill. The turn is journaled directly, so a live Claude process was not interrupted.Changelog
Added: An optional Stop button over a terminal interrupts a running Claude Code or Codex turn (Settings > Terminal > Agent Stop Button).
