--- name: cancel description: Cancel any active OMX mode (autopilot, ralph, ultrawork, ecomode, ultraqa, swarm, ultrapilot, pipeline, team) --- # Cancel Skill Intelligent cancellation that detects and cancels the active OMX mode. **The cancel skill is the standard way to complete and exit any OMX 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) - **Ecomode**: Stops token-efficient parallel execution (standalone or linked to ralph) - **UltraQA**: Stops QA cycling workflow - **Swarm**: Stops coordinated agent swarm, releases claimed tasks - **Ultrapilot**: Stops parallel autopilot workers - **Pipeline**: Stops sequential agent pipeline - **Team**: Sends shutdown inbox to all workers, waits for exit, kills tmux session, clears linked ralph if present - **Team+Ralph (linked)**: Cancels team first (tmux shutdown + state cleanup), then clears ralph state ## Usage ``` /cancel ``` Or say: "cancelomc", "stopomc" ## Auto-Detection `/cancel` follows the session-aware state contract: - By default the command inspects the current session via `state_list_active` and `state_get_status`, navigating `.omx/state/sessions/{sessionId}/…` to discover which mode is active. - When a session id is provided or already known, that session-scoped path is authoritative. Legacy files in `.omx/state/*.json` are consulted only as a compatibility fallback if the session id is missing or empty. - Swarm is a shared SQLite/marker mode (`.omx/state/swarm.db` / `.omx/state/swarm-active.marker`) and is not session-scoped. - The default cleanup flow calls `state_clear` with the session id to remove only the matching session files; modes stay bound to their originating session. Active modes are still cancelled in dependency order: 1. Autopilot (includes linked ralph/ultraqa/ecomode cleanup) 2. Ralph (cleans its linked ultrawork or ecomode) 3. Ultrawork (standalone) 4. Ecomode (standalone) 5. UltraQA (standalone) 6. Swarm (standalone) 7. Ultrapilot (standalone) 8. Pipeline (standalone) 9. Team (tmux-based) 10. Plan Consensus (standalone) ## Force Clear All Use `--force` or `--all` when you need to erase every session plus legacy artifacts, e.g., to reset the workspace entirely. ``` /cancel --force ``` ``` /cancel --all ``` Steps under the hood: 1. `state_list_active` enumerates `.omx/state/sessions/{sessionId}/…` to find every known session. 2. `state_clear` runs once per session to drop that session’s files. 3. A global `state_clear` without `session_id` removes legacy files under `.omx/state/*.json`, `.omx/state/swarm*.db`, and compatibility artifacts (see list). 4. Team artifacts (`.omx/state/team/*/`, tmux sessions matching `omx-team-*`) are best-effort cleared as part of the legacy fallback. Every `state_clear` command honors the `session_id` argument, so even force mode still uses the session-aware paths first before deleting legacy files. Legacy compatibility list (removed only under `--force`/`--all`): - `.omx/state/autopilot-state.json` - `.omx/state/ralph-state.json` - `.omx/state/ralph-plan-state.json` - `.omx/state/ralph-verification.json` - `.omx/state/ultrawork-state.json` - `.omx/state/ecomode-state.json` - `.omx/state/ultraqa-state.json` - `.omx/state/swarm.db` - `.omx/state/swarm.db-wal` - `.omx/state/swarm.db-shm` - `.omx/state/swarm-active.marker` - `.omx/state/swarm-tasks.db` - `.omx/state/ultrapilot-state.json` - `.omx/state/ultrapilot-ownership.json` - `.omx/state/pipeline-state.json` - `.omx/state/plan-consensus.json` - `.omx/state/ralplan-state.json` - `.omx/state/boulder.json` - `.omx/state/hud-state.json` - `.omx/state/subagent-tracking.json` - `.omx/state/subagent-tracker.lock` - `.omx/state/rate-limit-daemon.pid` - `.omx/state/rate-limit-daemon.log` - `.omx/state/checkpoints/` (directory) - `.omx/state/sessions/` (empty directory cleanup after clearing sessions) ## Implementation Steps When you invoke this skill: ### 1. Parse Arguments ```bash # Check for --force or --all flags FORCE_MODE=false if [[ "$*" == *"--force"* ]] || [[ "$*" == *"--all"* ]]; then FORCE_MODE=true fi ``` ### 2. Detect Active Modes The skill now relies on the session-aware state contract rather than hard-coded file paths: 1. Call `state_list_active` to enumerate `.omx/state/sessions/{sessionId}/…` and discover every active session. 2. For each session id, call `state_get_status` to learn which mode is running (`autopilot`, `ralph`, `ultrawork`, etc.) and whether dependent modes exist. 3. If a `session_id` was supplied to `/cancel`, skip legacy fallback entirely and operate solely within that session path; otherwise, consult legacy files in `.omx/state/*.json` only if the state tools report no active session. Swarm remains a shared SQLite/marker mode outside session scoping. 4. Any cancellation logic in this doc mirrors the dependency order discovered via state tools (autopilot → ralph → …). ### 3A. Force Mode (if --force or --all) Use force mode to clear every session plus legacy artifacts via `state_clear`. Direct file removal is reserved for legacy cleanup when the state tools report no active sessions. ### 3B. Smart Cancellation (default) #### If Team Active (tmux-based) Teams are detected by checking for config files in `.omx/state/team/`: ```bash # Check for active teams ls .omx/state/team/*/config.json 2>/dev/null ``` **Two-pass cancellation protocol:** **Pass 1: Graceful Shutdown** ``` For each team found in .omx/state/team/: 1. Read config.json to get team_name and workers list 2. For each worker: a. Write shutdown inbox to .omx/state/team/{name}/workers/{worker}/inbox.md b. Send short trigger via tmux send-keys c. Wait up to 15 seconds for worker tmux pane to exit d. If still alive: mark as unresponsive ``` **Pass 2: Force Kill** ``` After graceful pass: 1. For each remaining alive worker: a. Send C-c via tmux send-keys b. Wait 2 seconds c. Kill the tmux window if still alive 2. Destroy the tmux session: tmux kill-session -t omx-team-{name} ``` **Cleanup:** ``` 1. Strip AGENTS.md team worker overlay () 2. Remove team state directory: rm -rf .omx/state/team/{name}/ 3. Clear team mode state: state_clear(mode="team") 4. Check for linked ralph: state_read(mode="ralph") — if linked_team is true: a. Clear ralph state: state_clear(mode="ralph") b. Clear linked ultrawork if present: state_clear(mode="ultrawork") 5. Emit structured cancel report ``` **Structured Cancel Report:** ``` Team "{team_name}" cancelled: - Workers signaled: N - Graceful exits: M - Force killed: K - tmux session destroyed: yes/no - State cleaned up: yes/no ``` **Implementation note:** The cancel skill is executed by the LLM, not as a bash script. When you detect an active team: 1. Check `.omx/state/team/*/config.json` for active teams 2. For each worker in config.workers, write shutdown inbox and send trigger 3. Wait briefly for workers to exit (15s timeout) 4. Force kill remaining workers via tmux 5. Destroy tmux session: `tmux kill-session -t omx-team-{name}` 6. Strip AGENTS.md overlay 7. Remove state: `rm -rf .omx/state/team/{name}/` 8. `state_clear(mode="team")` 9. Report structured summary to user #### If Autopilot Active Call `cancelAutopilot()` from `src/hooks/autopilot/cancel.ts:27-78`: ```bash # Autopilot handles its own cleanup + ralph + ultraqa # Just mark autopilot as inactive (preserves state for resume) if [[ -f .omx/state/autopilot-state.json ]]; then # Clean up ralph if active if [[ -f .omx/state/ralph-state.json ]]; then RALPH_STATE=$(cat .omx/state/ralph-state.json) LINKED_UW=$(echo "$RALPH_STATE" | jq -r '.linked_ultrawork // false') # Clean linked ultrawork first if [[ "$LINKED_UW" == "true" ]] && [[ -f .omx/state/ultrawork-state.json ]]; then rm -f .omx/state/ultrawork-state.json echo "Cleaned up: ultrawork (linked to ralph)" fi # Clean ralph rm -f .omx/state/ralph-state.json rm -f .omx/state/ralph-verification.json echo "Cleaned up: ralph" fi # Clean up ultraqa if active if [[ -f .omx/state/ultraqa-state.json ]]; then rm -f .omx/state/ultraqa-state.json echo "Cleaned up: ultraqa" fi # Mark autopilot inactive but preserve state CURRENT_STATE=$(cat .omx/state/autopilot-state.json) CURRENT_PHASE=$(echo "$CURRENT_STATE" | jq -r '.phase // "unknown"') echo "$CURRENT_STATE" | jq '.active = false' > .omx/state/autopilot-state.json echo "Autopilot cancelled at phase: $CURRENT_PHASE. Progress preserved for resume." echo "Run /autopilot to resume." fi ``` #### If Ralph Active (but not Autopilot) Call `clearRalphState()` + `clearLinkedUltraworkState()` from `src/hooks/ralph-loop/index.ts:147-182`: ```bash if [[ -f .omx/state/ralph-state.json ]]; then # Check if ultrawork is linked RALPH_STATE=$(cat .omx/state/ralph-state.json) LINKED_UW=$(echo "$RALPH_STATE" | jq -r '.linked_ultrawork // false') # Clean linked ultrawork first if [[ "$LINKED_UW" == "true" ]] && [[ -f .omx/state/ultrawork-state.json ]]; then UW_STATE=$(cat .omx/state/ultrawork-state.json) UW_LINKED=$(echo "$UW_STATE" | jq -r '.linked_to_ralph // false') # Only clear if it was linked to ralph if [[ "$UW_LINKED" == "true" ]]; then rm -f .omx/state/ultrawork-state.json echo "Cleaned up: ultrawork (linked to ralph)" fi fi # Clean ralph state rm -f .omx/state/ralph-state.json rm -f .omx/state/ralph-plan-state.json rm -f .omx/state/ralph-verification.json echo "Ralph cancelled. Persistent mode deactivated." fi ``` #### If Ultrawork Active (standalone, not linked) Call `deactivateUltrawork()` from `src/hooks/ultrawork/index.ts:150-173`: ```bash if [[ -f .omx/state/ultrawork-state.json ]]; then # Check if linked to ralph UW_STATE=$(cat .omx/state/ultrawork-state.json) LINKED=$(echo "$UW_STATE" | jq -r '.linked_to_ralph // false') if [[ "$LINKED" == "true" ]]; then echo "Ultrawork is linked to Ralph. Use /cancel to cancel both." exit 1 fi # Remove local state rm -f .omx/state/ultrawork-state.json echo "Ultrawork cancelled. Parallel execution mode deactivated." fi ``` #### If UltraQA Active (standalone) Call `clearUltraQAState()` from `src/hooks/ultraqa/index.ts:107-120`: ```bash if [[ -f .omx/state/ultraqa-state.json ]]; then rm -f .omx/state/ultraqa-state.json echo "UltraQA cancelled. QA cycling workflow stopped." fi ``` #### No Active Modes ```bash echo "No active OMX modes detected." echo "" echo "Checked for:" echo " - Autopilot (.omx/state/autopilot-state.json)" echo " - Ralph (.omx/state/ralph-state.json)" echo " - Ultrawork (.omx/state/ultrawork-state.json)" echo " - UltraQA (.omx/state/ultraqa-state.json)" echo "" echo "Use --force to clear all state files anyway." ``` ## Implementation Notes The cancel skill runs as follows: 1. Parse the `--force` / `--all` flags, tracking whether cleanup should span every session or stay scoped to the current session id. 2. Use `state_list_active` to enumerate known session ids and `state_get_status` to learn the active mode (`autopilot`, `ralph`, `ultrawork`, etc.) for each session. 3. When operating in default mode, call `state_clear` with that session_id to remove only the session’s files, then run mode-specific cleanup (autopilot → ralph → …) based on the state tool signals. 4. In force mode, iterate every active session, call `state_clear` per session, then run a global `state_clear` without `session_id` to drop legacy files (`.omx/state/*.json`, compatibility artifacts) and report success. Swarm remains a shared SQLite/marker mode outside session scoping. 5. Team artifacts (`.omx/state/team/*/`, tmux sessions matching `omx-team-*`) remain best-effort cleanup items invoked during the legacy/global pass. State tools always honor the `session_id` argument, so even force mode still clears the session-scoped paths before deleting compatibility-only legacy state. Mode-specific subsections below describe what extra cleanup each handler performs after the state-wide operations finish. ## Messages Reference | Mode | Success Message | |------|-----------------| | Autopilot | "Autopilot cancelled at phase: {phase}.
