# Cancel Skill

Intelligent cancellation that detects and cancels the active OMD mode.

**The cancel skill is the standard way to complete and exit any OMD 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

## Usage

```
/cancel
```

Or say: "cancelomc", "stopomc"

## Auto-Detection

The skill checks state files to determine what's active:
- `.omd/state/autopilot-state.json` → Autopilot detected
- `.omd/state/ralph-state.json` → Ralph detected
- `.omd/state/ultrawork-state.json` → Ultrawork detected
- `.omd/state/ecomode-state.json` → Ecomode detected
- `.omd/state/ultraqa-state.json` → UltraQA detected
- `.omd/state/swarm.db` → Swarm detected (SQLite database)
- `.omd/state/ultrapilot-state.json` → Ultrapilot detected
- `.omd/state/pipeline-state.json` → Pipeline detected
- `.omd/state/plan-consensus.json` → Plan Consensus detected
- `.omd/state/ralplan-state.json` → Plan Consensus detected (legacy)

If multiple modes are active, they're cancelled in order of dependency:
1. Autopilot (includes ralph/ultraqa/ecomode cleanup)
2. Ralph (includes linked ultrawork OR ecomode cleanup)
3. Ultrawork (standalone)
4. Ecomode (standalone)
5. UltraQA (standalone)
6. Swarm (standalone)
7. Ultrapilot (standalone)
8. Pipeline (standalone)
9. Plan Consensus (standalone)

## Force Clear All

To clear ALL state files regardless of what's active:

```
/cancel --force
```

Or use the `--all` alias:

```
/cancel --all
```

This removes all state files:
- `.omd/state/autopilot-state.json`
- `.omd/state/ralph-state.json`
- `.omd/state/ultrawork-state.json`
- `.omd/state/ecomode-state.json`
- `.omd/state/ultraqa-state.json`
- `.omd/state/swarm.db`
- `.omd/state/swarm.db-wal`
- `.omd/state/swarm.db-shm`
- `.omd/state/swarm-active.marker`
- `.omd/state/ultrapilot-state.json`
- `.omd/state/pipeline-state.json`
- `.omd/state/plan-consensus.json`
- `.omd/state/ralplan-state.json`

## 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

```bash
# Check which modes are active
AUTOPILOT_ACTIVE=false
RALPH_ACTIVE=false
ULTRAWORK_ACTIVE=false
ECOMODE_ACTIVE=false
ULTRAQA_ACTIVE=false

if [[ -f .omd/state/autopilot-state.json ]]; then
  AUTOPILOT_ACTIVE=$(cat .omd/state/autopilot-state.json | jq -r '.active // false')
fi

if [[ -f .omd/state/ralph-state.json ]]; then
  RALPH_ACTIVE=$(cat .omd/state/ralph-state.json | jq -r '.active // false')
fi

if [[ -f .omd/state/ultrawork-state.json ]]; then
  ULTRAWORK_ACTIVE=$(cat .omd/state/ultrawork-state.json | jq -r '.active // false')
fi

if [[ -f .omd/state/ecomode-state.json ]]; then
  ECOMODE_ACTIVE=$(cat .omd/state/ecomode-state.json | jq -r '.active // false')
fi

if [[ -f .omd/state/ultraqa-state.json ]]; then
  ULTRAQA_ACTIVE=$(cat .omd/state/ultraqa-state.json | jq -r '.active // false')
fi

PLAN_CONSENSUS_ACTIVE=false

# Check both new and legacy locations
if [[ -f .omd/state/plan-consensus.json ]]; then
  PLAN_CONSENSUS_ACTIVE=$(cat .omd/state/plan-consensus.json | jq -r '.active // false')
elif [[ -f .omd/state/ralplan-state.json ]]; then
  PLAN_CONSENSUS_ACTIVE=$(cat .omd/state/ralplan-state.json | jq -r '.active // false')
fi
```

### 3A. Force Mode (if --force or --all)

```bash
if [[ "$FORCE_MODE" == "true" ]]; then
  echo "FORCE CLEAR: Removing all OMD state files..."

  # Remove local state files
  rm -f .omd/state/autopilot-state.json
  rm -f .omd/state/ralph-state.json
  rm -f .omd/state/ultrawork-state.json
  rm -f .omd/state/ecomode-state.json
  rm -f .omd/state/ultraqa-state.json
  rm -f .omd/state/ralph-plan-state.json
  rm -f .omd/state/ralph-verification.json
  rm -f .omd/state/swarm.db
  rm -f .omd/state/swarm.db-wal
  rm -f .omd/state/swarm.db-shm
  rm -f .omd/state/swarm-active.marker
  rm -f .omd/state/ultrapilot-state.json
  rm -f .omd/state/pipeline-state.json
  rm -f .omd/state/plan-consensus.json
  rm -f .omd/state/ralplan-state.json

  echo "All OMD modes cleared. You are free to start fresh."
  exit 0
fi
```

### 3B. Smart Cancellation (default)

#### 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 .omd/state/autopilot-state.json ]]; then
  # Clean up ralph if active
  if [[ -f .omd/state/ralph-state.json ]]; then
    RALPH_STATE=$(cat .omd/state/ralph-state.json)
    LINKED_UW=$(echo "$RALPH_STATE" | jq -r '.linked_ultrawork // false')

    # Clean linked ultrawork first
    if [[ "$LINKED_UW" == "true" ]] && [[ -f .omd/state/ultrawork-state.json ]]; then
      rm -f .omd/state/ultrawork-state.json
      echo "Cleaned up: ultrawork (linked to ralph)"
    fi

    # Clean ralph
    rm -f .omd/state/ralph-state.json
    rm -f .omd/state/ralph-verification.json
    echo "Cleaned up: ralph"
  fi

  # Clean up ultraqa if active
  if [[ -f .omd/state/ultraqa-state.json ]]; then
    rm -f .omd/state/ultraqa-state.json
    echo "Cleaned up: ultraqa"
  fi

  # Mark autopilot inactive but preserve state
  CURRENT_STATE=$(cat .omd/state/autopilot-state.json)
  CURRENT_PHASE=$(echo "$CURRENT_STATE" | jq -r '.phase // "unknown"')
  echo "$CURRENT_STATE" | jq '.active = false' > .omd/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 .omd/state/ralph-state.json ]]; then
  # Check if ultrawork is linked
  RALPH_STATE=$(cat .omd/state/ralph-state.json)
  LINKED_UW=$(echo "$RALPH_STATE" | jq -r '.linked_ultrawork // false')

  # Clean linked ultrawork first
  if [[ "$LINKED_UW" == "true" ]] && [[ -f .omd/state/ultrawork-state.json ]]; then
    UW_STATE=$(cat .omd/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 .omd/state/ultrawork-state.json
      echo "Cleaned up: ultrawork (linked to ralph)"
    fi
  fi

  # Clean ralph state
  rm -f .omd/state/ralph-state.json
  rm -f .omd/state/ralph-plan-state.json
  rm -f .omd/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 .omd/state/ultrawork-state.json ]]; then
  # Check if linked to ralph
  UW_STATE=$(cat .omd/state/ultrawork-state.json)
  LINKED=$(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 .omd/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 .omd/state/ultraqa-state.json ]]; then
  rm -f .omd/state/ultraqa-state.json
  echo "UltraQA cancelled. QA cycling workflow stopped."
fi
```

#### No Active Modes

```bash
echo "No active OMD modes detected."
echo ""
echo "Checked for:"
echo "  - Autopilot (.omd/state/autopilot-state.json)"
echo "  - Ralph (.omd/state/ralph-state.json)"
echo "  - Ultrawork (.omd/state/ultrawork-state.json)"
echo "  - UltraQA (.omd/state/ultraqa-state.json)"
echo ""
echo "Use --force to clear all state files anyway."
```

| Ralph | "Ralph cancelled. Persistent mode deactivated." |
| Ultrawork | "Ultrawork cancelled. Parallel execution mode deactivated." |
| Ecomode | "Ecomode cancelled. Token-efficient execution mode deactivated." |
| UltraQA | "UltraQA cancelled. QA cycling workflow stopped." |
| Swarm | "Swarm cancelled. Coordinated agents stopped." |

## What Gets Preserved

| Mode | State Preserved | Resume Command |
|------|-----------------|----------------|
| Autopilot | Yes (phase, files, spec, plan, verdicts) | `/autopilot` |
| Ralph | No | N/A |
| Ultrawork | No | N/A |

## Notes

- **Dependency-aware**: Autopilot cancellation cleans up Ralph and UltraQA
- **Link-aware**: Ralph cancellation cleans up linked Ultrawork or Ecomode
- **Safe**: Only clears linked Ultrawork, preserves standalone Ultrawork
- **Local-only**: Clears state files in `.omd/state/` directory
- **Resume-friendly**: Autopilot state is preserved for seamless resume
