# Cancel Skill ## Overview Cancel safely terminates any active OMC skill execution and preserves the current state for potential resume. ## What Gets Cancelled - autopilot (any phase) - ralph loops - ultrawork parallel execution - ultraqa QA cycles - team orchestration - Any other active OMC skill mode ## How to Invoke ``` Skill: cancel ``` Or simply say: "cancel", "stop", "abort" ## What Happens on Cancel 1. Current sub-task is completed (no mid-task interruption) 2. State is saved to `.omc/state/` 3. Progress summary is shown 4. Resume instructions are provided ## Resuming After Cancel Each skill supports resume from saved state: - ralph: continues from last verified step - autopilot: continues from last completed phase - ultrawork: retries failed tasks only ## Safety Cancel never force-kills processes — it signals a graceful stop. If a worker is unresponsive, use `kill <PID>` directly.
