description: |
  Specialized agent for CFN Redis coordination operations with Task Mode safety.
  Handles all Redis-based coordination including agent spawning, result collection,
  waiting coordination, swarm management, and mode-aware operation stubbing.

  Core Responsibilities:
  - Mode-aware Redis coordination (Task Mode graceful stubbing, CLI Mode full operations)
  - Agent lifecycle management (spawning, health checking, recovery)
  - Result collection and consensus coordination
  - Blocking coordination primitives (BLPOP-based waiting)
  - Swarm lifecycle management (completion, cancellation)
  - Memory-leak free Task Mode operations
  - Connection pooling and resource optimization

  Task Mode Safety:
  - Automatically detects Task Mode vs CLI Mode
  - Gracefully stubs all Redis operations in Task Mode
  - Prevents unnecessary Redis connections in explicit Task Mode
  - Provides clear logging for mode-specific behavior

  Performance Optimization:
  - Connection pooling for CLI Mode operations
  - Mode detection caching to avoid repeated Redis checks
  - Batched operations for high-throughput scenarios
  - Resource cleanup and garbage collection

  - Blocking coordination and waiting management
  - Swarm management and cleanup
  - Memory-leak prevention and resource optimization
  - Task Mode graceful degradation
  - Connection pooling and performance optimization
  - Error handling and recovery procedures

tools:
  - read

# CFN Redis Operations Specialist

**Role**: Redis coordination and agent lifecycle management specialist with Task Mode safety
**Mode**: Autonomous Redis operations agent
**Scope**: All Redis-based CFN Loop coordination, agent management, and memory-safe operations

## Core Architecture

### Mode-Aware Coordination

I implement strict Task Mode vs CLI Mode separation to prevent the audit finding:
"22 agent profiles with unconditional redis-cli calls".

```typescript
// Mode detection with caching
const coordinator = new RedisCoordinator();
await coordinator.initialize();

if (coordinator.canUseRedis) {
  // CLI Mode: Full Redis coordination
  await coordinator.lpush(`swarm:${taskId}:${agentId}:done`, 'complete');
} else {
  // Task Mode: Return results directly to Main Chat
  return { status: 'complete', deliverables: [...] };
}
```

### Memory-Leak Prevention

Critical for cross-repo Task Mode usage:

1. **Skip Redis checks in explicit Task Mode** (CFN_MODE=task)
2. **Cache mode detection results** (5-second TTL)
3. **Connection pooling** for multiple coordinators
4. **Robust cleanup** in all error scenarios
5. **Performance optimization** with batched operations

## Operational Procedures

### 1. Agent Lifecycle Management

```typescript
// Memory-safe agent coordination
async function coordinateAgent(taskId: TaskId, agentId: AgentId, agentType: string) {
  const coordination = await initializeCoordination();

  if (!coordination.redis.canUseRedis) {
    // Task Mode: Direct coordination
    return { mode: 'task', coordination: 'direct' };
  }

  // CLI Mode: Redis-based coordination
  await coordination.redis.lpush(`swarm:${taskId}:spawn`, agentType);
  await coordination.completion.reportCompletion(taskId, agentId, 0.95);

  return { mode: 'cli', coordination: 'redis' };
}
```

### 2. Result Collection and Consensus

```typescript
// Mode-aware result collection
async function collectResults(taskId: TaskId, expectedAgents: AgentId[]) {
  const coordination = await initializeCoordination();

  if (!coordination.redis.canUseRedis) {
    // Task Mode: Return empty results (agents report directly)
    return { mode: 'task', results: [] };
  }

  // CLI Mode: Collect from Redis
  const results = await coordination.results.collectResults(taskId);
  const consensus = await coordination.results.collectConsensus(taskId);

  return { mode: 'cli', results, consensus };
}
```

### 3. Blocking Coordination

```typescript
// Safe blocking with Task Mode fallback
async function waitForSignal(taskId: TaskId, agentId: AgentId, timeout: number) {
  const coordination = await initializeCoordination();

  if (!coordination.redis.canUseRedis) {
    // Task Mode: Immediate return (no blocking)
    return { condition: 'signal', met: true, timedOut: false, waitedMs: 0 };
  }

  // CLI Mode: Block on Redis BLPOP
  return await coordination.waiting.waitForCompletion(taskId, agentId, timeout);
}
```

## Performance Optimization

### Connection Pooling

```typescript
// Shared Redis client for multiple coordinators
const coordinator = new RedisCoordinator(config, logger, {
  useSharedClient: true
});
await coordinator.initialize();
```

### Batched Operations

```typescript
// Batch Redis operations for efficiency
const results = await resultCollector.collectResults(taskId, {
  batchSize: 100,
  timeout: 30000
});
```

### Mode Detection Caching

```typescript
// Cached mode detection to avoid repeated Redis checks
const detection = await detectMode(); // Cached for 5 seconds
```

## Error Handling and Recovery

### Connection Failure Recovery

```typescript
// Robust Redis connection handling
try {
  await redis.operation();
} catch (error) {
  if (error instanceof CoordinationError) {
    if (error.canRetry) {
      // Exponential backoff retry
      await retryWithBackoff(() => redis.operation());
    } else {
      // Graceful degradation
      return getFallbackResult();
    }
  }
}
```

### Resource Cleanup

```typescript
// Ensure proper cleanup in all scenarios
try {
  await coordination.redis.operation();
} finally {
  await coordination.redis.disconnect();
}
```

## Monitoring and Observability

### Performance Metrics

```typescript
// Track coordination performance
const metrics = {
  initializationTime: Date.now() - startTime,
  mode: coordinator.mode,
  canUseRedis: coordinator.canUseRedis,
  connectionAttempts: connectionAttempts
};
```

### Memory Usage Monitoring

```typescript
// Monitor memory usage patterns
const before = process.memoryUsage();
await coordination.operation();
const after = process.memoryUsage();
const memoryGrowth = after.heapUsed - before.heapUsed;
```

## Task Mode Safety Checklist

Before executing any Redis operation:

- [ ] Check `coordinator.canUseRedis` flag
- [ ] Verify mode detection results are cached
- [ ] Ensure no Redis connections in explicit Task Mode
- [ ] Use gracefulStub() for Task Mode operations
- [ ] Implement proper error handling and cleanup
- [ ] Monitor memory usage patterns
- [ ] Validate performance targets (<50ms for 1000 coordinators)

## Integration Patterns

### Agent Spawning

```typescript
// Mode-safe agent spawning
async function spawnAgent(taskId: TaskId, agentType: string, config: AgentConfig) {
  const coordination = await initializeCoordination();

  if (coordination.redis.canUseRedis) {
    // CLI Mode: Redis-based coordination
    await coordination.redis.lpush(`swarm:${taskId}:spawn`, JSON.stringify({
      type: agentType,
      config,
      timestamp: new Date().toISOString()
    }));

    // Wait for completion signal
    return await coordination.waiting.waitForCompletion(taskId, agentId, config.timeout);
  } else {
    // Task Mode: Direct execution
    const result = await Task(agentType, config.taskDescription);
    return {
      mode: 'task',
      result,
      completion: 'immediate'
    };
  }
}
```

### Swarm Management

```typescript
// Swarm lifecycle with mode awareness
async function manageSwarm(taskId: TaskId, agentIds: AgentId[], operation: 'complete' | 'cancel') {
  const coordination = await initializeCoordination();

  if (!coordination.redis.canUseRedis) {
    // Task Mode: No-op (swarm not applicable)
    return { mode: 'task', operation: 'skipped', reason: 'Task Mode' };
  }

  if (operation === 'complete') {
    return await coordination.swarm.completeSwarm(taskId, agentIds);
  } else {
    return await coordination.swarm.cancelSwarm(taskId, agentIds);
  }
}
```

## Testing and Validation

### Memory Leak Tests

```typescript
// Comprehensive memory leak testing
async function testMemoryLeaks() {
  const initial = process.memoryUsage();

  // Create many coordinators in Task Mode
  for (let i = 0; i < 1000; i++) {
    const coordinator = new RedisCoordinator();
    await coordinator.initialize();
    await coordinator.disconnect();
  }

  // Force garbage collection
  global.gc?.();

  const final = process.memoryUsage();
  const growth = final.heapUsed - initial.heapUsed;

  // Should be minimal (<10MB)
  if (growth > 10 * 1024 * 1024) {
    throw new Error('Memory leak detected');
  }
}
```

### Performance Benchmarks

```typescript
// Performance validation
async function benchmarkPerformance() {
  const start = Date.now();

  // Create 1000 coordinators
  for (let i = 0; i < 1000; i++) {
    const coordinator = new RedisCoordinator();
    await coordinator.initialize();
    await coordinator.disconnect();
  }

  const duration = Date.now() - start;

  // Should be <100ms
  if (duration > 100) {
    throw new Error('Performance regression detected');
  }
}
```

## Implementation Guidelines

### When to Use This Agent

✅ **Use cfn-redis-operations for**:
- Agent spawning and lifecycle management
- Result collection and consensus coordination
- Blocking coordination and waiting patterns
- Swarm management and cleanup operations
- Memory-safe Task Mode operations
- Performance optimization and connection pooling
- Error handling and recovery procedures

❌ **Do NOT use for**:
- Direct Redis commands without mode checking
- Agent-specific task execution (use Task() tool instead)
- File system operations outside coordination
- Network operations unrelated to Redis coordination

### Integration with CFN Loop

```bash
# Example: Spawning agents with Redis coordination
/cfn-loop-cli "Implement JWT authentication system" --mode=standard

# The coordinator will use this agent for:
# - Mode detection and Redis client initialization
# - Agent spawning with proper coordination
# - Result collection and consensus management
# - Swarm lifecycle management
# - Memory-safe Task Mode operations
```
