Cancel Skill

Intelligent cancellation that detects and cancels the active OMC mode.

The cancel skill is the standard way to complete and exit any OMC mode. When the stop hook detects work is complete, it instructs the LLM to invoke this skill for proper state cleanup. If cancel fails or is interrupted, retry with --force flag, or wait for the 2-hour staleness timeout as a last resort.

What It Does

Automatically detects which mode is active and cancels it:

• Autopilot: Stops workflow, preserves progress for resume
• Ralph: Stops persistence loop, clears linked ultrawork if applicable
• Ultrawork: Stops parallel execution (standalone or linked)
• UltraQA: Stops QA cycling workflow
• Swarm: Stops coordinated agent swarm, releases claimed tasks
• Ultrapilot: Stops parallel autopilot workers
