name: cancel description: Cancel any active OMX mode (autopilot, ralph, ultrawork, ecomode, ultraqa, swarm, ultrapilot, pipeline, team)

Cancel Skill

When to use

Use /cancel (or cancelomc / stopomc) to stop an active OMX mode and perform its documented cleanup. Read AGENTS.md#durable-runtime-invariants-canonical-ssot first; it is the invariant authority for scope, ownership, hooks, and Team cleanup.

Inputs and preconditions

• Accepted forms are /cancel and /cancel --force.
• 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 proven linked Ultrawork/Ecomode state in the same scope. Confirm the post-conditions in docs/contracts/ralph-cancel-contract.md.
5. Clear standalone modes only after proving they are not linked to another active mode.
6. For Team, inspect the runtime with omx team status <team> --json; use omx team shutdown <team> after the normal completion gate, or follow the explicit abort path.
7. Clear only the selected mode/session state through the state API, for example:

   omx state clear --input '{"mode":"<mode>","session_id":"<session>"}' --json
   

8. With --force, perform its documented native-stop cleanup. Report rollback or cleanup failures rather than claiming success.

Exit and evidence

Report one result per selected mode: mode, scope/session, terminal phase, preserved state, linked cleanup, and any refusal reason. A clean no-op reports No active OMX modes detected. Include Team status and shutdown evidence when Team was selected.
