Add stop thread keybinding command

[jakeleventhal]

Summary

Screen.Recording.2026-07-22.at.4.36.45.PM.mov

• add a typed thread.stop keybinding command without assigning a default shortcut
• expose all static commands, including unbound ones, in the keybinding picker
• route the command through the focused thread's existing turn-interrupt behavior

Testing

• vp test run packages/contracts/src/keybindings.test.ts apps/web/src/keybindings.test.ts apps/web/src/components/settings/KeybindingsSettings.logic.test.ts (58 tests)
• vp run typecheck in packages/contracts
• vp run typecheck in apps/web
• targeted vp fmt --check and vp lint for all changed files
• integrated browser verification with a real running Codex turn and a custom thread.stop binding; the turn returned to ready with no active turn or error

Note

Add thread.stop keybinding command to interrupt running thread turns

• Adds thread.stop to the thread command registry in the keybinding contract, with no default shortcut assigned. Users must bind it in Keybindings settings.
• Introduces buildRunningThreadTurnInterruptInput in ChatView.logic.ts, which only produces interrupt input when the UI phase and thread session are both running; it preserves the existing optional active-turn behavior, allowing a thread-only request before a turn ID is projected.
• Updates ChatView to use a memoized interrupt callback behind the new guard and handle thread.stop in the keyboard shortcut handler, adding preview focus and preview-open state to the keybinding context.
• Behavioral Change: thread.stop is ignored when interruption is unavailable and repeated keydown events do not trigger multiple interrupts; interrupt requests are now sent only when both the current phase and thread session are running.

Note

Low Risk
Client-side shortcut and interrupt wiring only; reuses existing interruptThreadTurn behavior with stricter gating when the thread is not running.

Overview
Adds a thread.stop keybinding command (no default shortcut) so users can interrupt the active thread turn from the keyboard after assigning a binding in Settings or keybindings.json.

ChatView wires thread.stop through the global shortcut handler: it only runs when both the UI session phase and the thread session are running, ignores key repeat, and does not consume the key when stop is unavailable so contextual shortcuts (e.g. Escape closing a dialog) still work. Interrupt logic is centralized in buildRunningThreadTurnInterruptInput, which delegates to existing turn-interrupt input building (including the case where a running session has not projected activeTurnId yet). Shortcut resolution also gains previewFocus / previewOpen context for when expressions.

Contracts, keybinding resolution tests, settings command-picker expectations, user docs, and ChatView logic tests are updated accordingly; thread.stop appears among static assignable commands even though it is not in default resolved bindings.

Summary by CodeRabbit

• New Features

  • Added a thread.stop command to interrupt the active turn in the focused thread.
  • Users can assign custom shortcuts for this command in Settings → Keybindings.
  • Shortcut handling respects preview focus and only interrupts when a turn is running.

• Documentation

  • Documented the thread.stop keybinding command and its configuration.

📝 Walkthrough

Walkthrough

The change adds the thread.stop keybinding, validates running-thread interruption inputs, and connects the command to guarded interruption handling in ChatView. Tests cover command parsing, resolution, settings, and turn-state scenarios.

Changes

Thread stop interruption

Layer / File(s)	Summary
Interrupt contract and validation packages/contracts/src/keybindings.ts, packages/contracts/src/keybindings.test.ts, apps/web/src/components/ChatView.logic.ts, apps/web/src/components/ChatView.logic.test.ts	The keybinding contract accepts thread.stop. The new helper returns an interrupt input only for running sessions. Tests cover active, missing, non-running, and unprojected turns.
ChatView interruption handling apps/web/src/components/ChatView.tsx	ChatView resolves preview context, handles thread.stop, prevents repeated events, and invokes interruption only when the active thread can be interrupted.
Keybinding settings and coverage apps/web/src/components/settings/KeybindingsSettings.logic.test.ts, apps/web/src/keybindings.test.ts, docs/user/keybindings.md	Settings include thread.stop without a default binding. Tests cover Escape and preview-focus conditions. Documentation describes the command.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 6c083

The new configurable stop command interrupts focused running turns; its session-status guard lacks one targeted regression case, creating limited risk of a future change allowing interruption outside the intended running state.

Approvability

Verdict: Approved at 6c0830c

Macroscope's review found this PR approvable — Adds an unbound thread.stop command that users must explicitly configure, while reusing the existing interrupt behavior and leaving default shortcuts unchanged. The implementation is small, guarded, and covered by focused tests, with documentation and contract updates only.

Dismissing prior approval to re-evaluate cd01855

[Mnigos]

Ran this locally and it holds up. All four touched test files pass, and if I swap the logic file and the contract back to main, exactly the four new tests fail, so they actually pin the behavior. Merges clean, typecheck clean.

I went in expecting one problem and didn't find it: since the shared onInterrupt now requires session.status === "running", I thought the composer's Stop button might silently do nothing in some window. It can't, derivePhase only reports running for a running session, and the null activeTurnId case still works.

Two tiny nits, ignore freely: that session.status check is already implied by derivePhase, and the docs paragraph feels lost next to filePicker instead of the other thread.* commands. One heads up for whoever merges: adding previewFocus/previewOpen to the shortcut context changes how when resolves for every command, which I think is the right call, just not only about thread.stop.

Cover the running-phase, ready-session case.

Lines 1301-1302 fail the phase guard and do not test the session-status guard. Pass "running" as the phase for this ready-session case. This verifies that thread.session.status !== "running" still prevents an interrupt.

Proposed test change

-      buildRunningThreadTurnInterruptInput(makeThread({ session: readySession }), "ready"),
+      buildRunningThreadTurnInterruptInput(makeThread({ session: readySession }), "running"),
