## Memory Coordination

### Shared Memory Updates
```json
{
  "key": "aqe/swarm/workflow-cli-commands/progress",
  "value": {
    "command": "list|pause|cancel",
    "status": "completed",
    "timestamp": "2025-10-06T...",
    "workflowId": "wf-xxx"
  },
  "partition": "workflow_cli",
  "ttl": 3600
}
```

### Hook Notifications
1. **Task Completion:**
   ```bash
   npx claude-flow@alpha hooks post-task \
     --task-id "workflow-cli-commands" \
     --results '{"commands":3,"tests":50,"status":"completed"}'
   ```

2. **Agent Notification:**
   ```bash
   npx claude-flow@alpha hooks notify \
     --message "Workflow CLI commands implemented"
   ```

---

## Usage Examples

### List Workflows
```bash
# Basic list
aqe workflow list

# Filtered by status
aqe workflow list --status running,paused

# Detailed with table format
aqe workflow list --detailed --format table --limit 10
```

### Pause Workflow
```bash
# Graceful pause with reason
aqe workflow pause wf-001 --reason "Manual review required"

# Immediate pause
aqe workflow pause wf-001 --immediate
```

### Cancel Workflow
```bash
# Graceful cancel with cleanup
aqe workflow cancel wf-001 \
  --reason "Requirements changed" \
  --preserve-results

# Force cancel with confirmation
aqe workflow cancel wf-001 \
  --force \
  --confirm \
  --clean-memory
```

## Architecture Highlights

### Design Patterns
1. **Command Pattern:** Each command is a separate module
2. **Strategy Pattern:** Different pause/cancel modes
3. **Template Method:** Shared validation and error handling
4. **Observer Pattern:** Agent notification system
5. **Memento Pattern:** State preservation and checkpoints

### Best Practices
- ✅ TDD approach (tests written first)
- ✅ Comprehensive error handling
- ✅ Input validation
- ✅ State preservation
- ✅ Audit logging
- ✅ Memory coordination
- ✅ Hook integration
- ✅ Type safety (TypeScript)
- ✅ Modular design
- ✅ Extensive documentation

---

## Integration with Existing MCP Tools

Commands integrate with existing MCP handlers:
- `workflow-execute.ts` - Execution engine
- `workflow-checkpoint.ts` - Checkpoint management
- `workflow-resume.ts` - Resume functionality

**Coordination Flow:**
```
CLI Command → Memory Manager → MCP Handlers → Agents
     ↓              ↓               ↓           ↓
  Validation → Checkpoints → Execution → Notification
     ↓              ↓               ↓           ↓
Error Handling → Audit Log → Cleanup → Progress Update
```
