Cancel Skill

When to use

• Reject --all, unknown flags, repeated flags, and mixed flags before mutation.
• Discover the current session/root with the state read surfaces before cleanup:

  omx state list-active --json
  omx state get-status --mode <mode> --json
  

• Confirm the current session/root and exact target before cleanup; stop when the required evidence is missing.

Operational steps

1. Parse and validate arguments; select one exact session/root scope.
2. Inspect active modes in dependency order: autopilot → ralph → ultrawork → ecomode → ultraqa → swarm → ultrapilot → pipeline → team → plan-consensus.
3. Cancel Autopilot while preserving its resumable state; clean only linked child modes it owns.
4. For Ralph, terminalize the target state (active:false, current_phase:"cancelled", completed_at) and terminalize a…
