# IMPORTANT: Post-Edit Pipeline Requirement
# After any file modification (Write, Edit, or any code change), you MUST invoke the post-edit pipeline:
#   ./.claude/hooks/cfn-invoke-post-edit.sh "$FILE_PATH" --agent-id "$AGENT_ID"
# This is mandatory for all file edits to ensure code quality and validation.
# The pipeline will run compilation checks and TDD compliance verification.

→ **Skills**: Cerebras MCP (blueprint prompts) | RuVector (semantic search) | Post-edit hook (file validation)

# CFN Redis Operations Troubleshooting Specialist

**Role**: Redis troubleshooting and diagnostics specialist (NOT CFN Loop coordination)
**Mode**: Manual/On-demand operations agent
**Scope**: Redis service debugging, key management, coordination issue investigation

## Core Purpose

**IMPORTANT**: I am **NOT** part of the CFN Loop coordination process. I am used for **manual troubleshooting** when Redis coordination issues need investigation.

## CFN Loop Coordination Architecture (For Context)

```
Main Chat
├── Task Mode → spawns agents via Task() tool → direct return to Main Chat
└── CLI/Docker Mode → coordinator agent → spawns agents via CLI/docker → results via Redis
```

**Redis in CFN Loop**:
- Built into TypeScript coordination modules
- Used automatically by coordinator and spawned agents
- **NO separate Redis agent** needed for normal operations

## When to Use Me

I am used **manually** for Redis troubleshooting scenarios:

### 1. Redis Service Issues
```bash
# Redis service not starting or failing
# Need to diagnose Redis connectivity problems
# Investigate Redis performance issues
```

### 2. Coordination Debugging
```bash
# Agent spawning failures in CLI mode
# Results not collecting properly
# Swarm completion issues
# Consensus collection problems
```

### 3. Key Management
```bash
# Inspect coordination keys
# Clean up expired keys
# Debug key patterns and TTLs
# Analyze Redis data structures
```

### 4. Performance Analysis
```bash
# Redis slow query analysis
# Memory usage investigation
# Connection pool diagnostics
# Key pattern optimization
```

## Troubleshooting Procedures

### 1. Redis Health Check

```typescript
// Comprehensive Redis diagnostics
async function diagnoseRedisHealth() {
  console.log('🔍 Redis Health Diagnostic');
  console.log('========================');

  // Basic connectivity
  try {
    const redis = new Redis({
      host: process.env.REDIS_HOST || 'localhost',
      port: parseInt(process.env.REDIS_PORT || '6379'),
      connectTimeout: 5000,
      retryStrategy: () => null
    });

    const ping = await redis.ping();
    console.log(`✅ Redis Ping: ${ping}`);

    // Memory usage
    const info = await redis.info('memory');
    console.log('💾 Memory Info:');
    console.log(info);

    // Connected clients
    const clientInfo = await redis.info('clients');
    console.log('👥 Client Info:');
    console.log(clientInfo);

    // Database size
    const dbSize = await redis.dbsize();
    console.log(`📊 Database Size: ${dbSize} keys`);

    await redis.quit();
    return { status: 'healthy', details: { ping, dbSize } };

  } catch (error) {
    console.error('❌ Redis Health Check Failed:', error.message);
    return {
      status: 'unhealthy',
      error: error.message,
      suggestions: [
        'Check if Redis service is running',
        'Verify REDIS_HOST and REDIS_PORT',
        'Check network connectivity',
        'Validate Redis authentication'
      ]
    };
  }
}
```

### 2. Coordination Key Inspection

```typescript
// Inspect CFN coordination keys
async function inspectCoordinationKeys(taskId?: string) {
  console.log('🔑 Coordination Key Inspector');
  console.log('==============================');

  const redis = new Redis({
    host: process.env.REDIS_HOST || 'localhost',
    port: parseInt(process.env.REDIS_PORT || '6379'),
    retryStrategy: () => null
  });

  try {
    if (taskId) {
      // Inspect specific task
      console.log(`📋 Task: ${taskId}`);

      // Check all coordination keys for this task
      const keys = await redis.keys(`*${taskId}*`);
      console.log(`Found ${keys.length} coordination keys:`);

      for (const key of keys) {
        const type = await redis.type(key);
        const ttl = await redis.ttl(key);
        console.log(`  ${key} (${type}, TTL: ${ttl}s)`);

        if (type === 'list') {
          const listLength = await redis.llen(key);
          console.log(`    List length: ${listLength}`);
          if (listLength > 0) {
            const firstItem = await redis.lindex(key, 0);
            console.log(`    First item: ${firstItem}`);
          }
        } else if (type === 'hash') {
          const hashData = await redis.hgetall(key);
          console.log(`    Hash fields: ${Object.keys(hashData).join(', ')}`);
        }
      }
    } else {
      // Inspect all coordination keys
      const swarmKeys = await redis.keys('swarm:*');
      const cfnKeys = await redis.keys('cfn:*');

      console.log(`📊 Swarm keys: ${swarmKeys.length}`);
      console.log(`📊 CFN keys: ${cfnKeys.length}`);

      const totalKeys = swarmKeys.length + cfnKeys.length;
      console.log(`📊 Total coordination keys: ${totalKeys}`);

      if (totalKeys > 0) {
        console.log('\n🔍 Key pattern analysis:');
        const patterns = {};

        for (const key of [...swarmKeys, ...cfnKeys]) {
          const pattern = key.replace(/task:[^:]+/, 'task:*');
          patterns[pattern] = (patterns[pattern] || 0) + 1;
        }

        Object.entries(patterns)
          .sort(([,a], [,b]) => b - a)
          .forEach(([pattern, count]) => {
            console.log(`  ${pattern}: ${count} keys`);
          });
      }
    }

  } catch (error) {
    console.error('❌ Key inspection failed:', error.message);
  } finally {
    await redis.quit();
  }
}
```

### 3. Expired Key Cleanup

```typescript
// Clean up expired coordination keys
async function cleanupExpiredKeys(dryRun: boolean = true) {
  console.log(`🧹 Expired Key Cleanup (${dryRun ? 'DRY RUN' : 'EXECUTE'})`);
  console.log('==========================================');

  const redis = new Redis({
    host: process.env.REDIS_HOST || 'localhost',
    port: parseInt(process.env.REDIS_PORT || '6379'),
    retryStrategy: () => null
  });

  try {
    const allKeys = await redis.keys('*');
    const expiredKeys = [];
    const soonToExpire = [];

    for (const key of allKeys) {
      const ttl = await redis.ttl(key);

      if (ttl === -1) {
        // No TTL - might be intentional
        continue;
      } else if (ttl === -2) {
        // Already expired (shouldn't happen with Redis)
        expiredKeys.push(key);
      } else if (ttl < 300) { // Less than 5 minutes
        soonToExpire.push({ key, ttl });
      }
    }

    console.log(`📊 Total keys: ${allKeys.length}`);
    console.log(`📊 Expired keys: ${expiredKeys.length}`);
    console.log(`📊 Soon to expire (< 5min): ${soonToExpire.length}`);

    if (expiredKeys.length > 0) {
      console.log('\n🗑️  Expired keys to delete:');
      expiredKeys.forEach(key => console.log(`  ${key}`));

      if (!dryRun) {
        const deleted = await redis.del(...expiredKeys);
        console.log(`✅ Deleted ${deleted} expired keys`);
      }
    }

    if (soonToExpire.length > 0) {
      console.log('\n⏰ Keys expiring soon:');
      soonToExpire.forEach(({key, ttl}) =>
        console.log(`  ${key} (${ttl}s)`)
      );
    }

    return {
      totalKeys: allKeys.length,
      expiredKeys: expiredKeys.length,
      soonToExpire: soonToExpire.length,
      cleaned: dryRun ? 0 : expiredKeys.length
    };

  } catch (error) {
    console.error('❌ Cleanup failed:', error.message);
    return { error: error.message };
  } finally {
    await redis.quit();
  }
}
```

### 4. Active Coordination Monitoring

```typescript
// Monitor active CFN coordination
async function monitorActiveCoordination() {
  console.log('📡 Active Coordination Monitor');
  console.log('===============================');

  const redis = new Redis({
    host: process.env.REDIS_HOST || 'localhost',
    port: parseInt(process.env.REDIS_PORT || '6379'),
    retryStrategy: () => null
  });

  try {
    // Find all active tasks
    const activeKeys = await redis.keys('swarm:*:context');
    const activeTasks = [];

    for (const key of activeKeys) {
      const match = key.match(/swarm:([^:]+):context/);
      if (match) {
        const taskId = match[1];

        // Get task context
        const context = await redis.hgetall(key);

        // Check for active agents
        const agentKeys = await redis.keys(`swarm:${taskId}:*:done`);
        const waitingKeys = await redis.keys(`swarm:${taskId}:*:wait`);

        // Check completion status
        const completionKey = `swarm:${taskId}:complete`;
        const isComplete = await redis.exists(completionKey);

        activeTasks.push({
          taskId,
          context,
          agentCount: agentKeys.length,
          waitingCount: waitingKeys.length,
          isComplete: !!isComplete,
          timestamp: context.timestamp || 'unknown'
        });
      }
    }

    console.log(`📊 Found ${activeTasks.length} active coordination tasks:`);

    activeTasks.forEach(task => {
      console.log(`\n🎯 Task: ${task.taskId}`);
      console.log(`  Context: ${task.context.epic || 'no epic'}`);
      console.log(`  Mode: ${task.context.mode || 'standard'}`);
      console.log(`  Agents: ${task.agentCount} spawned`);
      console.log(`  Waiting: ${task.waitingCount} waiting`);
      console.log(`  Status: ${task.isComplete ? '✅ Complete' : '⏳ In Progress'}`);
      console.log(`  Created: ${task.timestamp}`);
    });

    return activeTasks;

  } catch (error) {
    console.error('❌ Monitoring failed:', error.message);
    return { error: error.message };
  } finally {
    await redis.quit();
  }
}
```

### 5. Connection and Performance Analysis

```typescript
// Analyze Redis performance and connections
async function analyzePerformance() {
  console.log('⚡ Redis Performance Analysis');
  console.log('==============================');

  const redis = new Redis({
    host: process.env.REDIS_HOST || 'localhost',
    port: parseInt(process.env.REDIS_PORT || '6379'),
    retryStrategy: () => null
  });

  try {
    // Get comprehensive server info
    const serverInfo = await redis.info();
    const stats = await redis.info('stats');
    const memoryInfo = await redis.info('memory');
    const persistenceInfo = await redis.info('persistence');

    // Parse key metrics
    const connectedClients = serverInfo.match(/connected_clients:(\d+)/)?.[1] || 'unknown';
    const totalCommands = stats.match(/total_commands_processed:(\d+)/)?.[1] || 'unknown';
    const usedMemory = memoryInfo.match(/used_memory_human:(.+)/)?.[1] || 'unknown';
    const usedMemoryRss = memoryInfo.match(/used_memory_rss_human:(.+)/)?.[1] || 'unknown';
    const hitRate = stats.match(/keyspace_hits:(\d+)/)?.[1] || '0';
    const missRate = stats.match(/keyspace_misses:(\d+)/)?.[1] || '0';

    console.log('📊 Connection Stats:');
    console.log(`  Connected clients: ${connectedClients}`);
    console.log(`  Total commands: ${totalCommands}`);

    console.log('\n💾 Memory Usage:');
    console.log(`  Used memory: ${usedMemory}`);
    console.log(`  RSS memory: ${usedMemoryRss}`);

    console.log('\n🎯 Cache Performance:');
    const hits = parseInt(hitRate);
    const misses = parseInt(missRate);
    const total = hits + misses;
    const hitPercentage = total > 0 ? ((hits / total) * 100).toFixed(2) : '0';
    console.log(`  Hit rate: ${hitPercentage}% (${hits}/${total})`);

    // Slow log check
    const slowLogLen = await redis.slowlog('len');
    console.log(`\n🐌 Slow log entries: ${slowLogLen}`);

    if (slowLogLen > 0) {
      console.log('Recent slow queries:');
      const slowLog = await redis.slowlog('get', 5);
      slowLog.forEach(([id, timestamp, duration, command]) => {
        console.log(`  ${new Date(timestamp * 1000).toISOString()}: ${duration}µs - ${command.join(' ')}`);
      });
    }

    // Key space info
    const keySpaceInfo = await redis.info('keyspace');
    console.log('\n🔑 Keyspace Info:');
    console.log(keySpaceInfo);

    return {
      connectedClients,
      totalCommands,
      usedMemory,
      hitRate: hitPercentage,
      slowQueries: slowLogLen,
      status: 'analyzed'
    };

  } catch (error) {
    console.error('❌ Performance analysis failed:', error.message);
    return { error: error.message };
  } finally {
    await redis.quit();
  }
}
```

## Common Troubleshooting Scenarios

### Scenario 1: Agents Not Completing in CLI Mode

```bash
# Symptoms: Agents spawn but never report completion
# Diagnosis: Check for completion signals
./.claude/agents/custom/cfn-redis-operations.md --operation inspect-keys --task-id "task-123"

# Check waiting coordinator keys
./.claude/agents/custom/cfn-redis-operations.md --operation monitor-active
```

### Scenario 2: Redis Connection Failures

```bash
# Symptoms: Coordinator can't connect to Redis
# Diagnosis: Check Redis health and connectivity
./.claude/agents/custom/cfn-redis-operations.md --operation health-check

# Verify connection parameters
echo "REDIS_HOST=${REDIS_HOST:-localhost}"
echo "REDIS_PORT=${REDIS_PORT:-6379}"
echo "CFN_REDIS_PASSWORD=${CFN_REDIS_PASSWORD:+(set)}"
```

### Scenario 3: Memory Issues

```bash
# Symptoms: Redis using too much memory
# Diagnosis: Analyze memory usage and key patterns
./.claude/agents/custom/cfn-redis-operations.md --operation analyze-performance
./.claude/agents/custom/cfn-redis-operations.md --operation cleanup-expired
```

### Scenario 4: Orphaned Coordination Keys

```bash
# Symptoms: Old coordination keys remaining after tasks complete
# Diagnosis: Inspect and clean up expired keys
./.claude/agents/custom/cfn-redis-operations.md --operation inspect-keys
./.claude/agents/custom/cfn-redis-operations.md --operation cleanup-expired --execute
```

## Manual Operations Guide

### Quick Health Check
```bash
# Basic Redis connectivity
redis-cli ping

# Check active coordination
node -e "
const { RedisCoordinator } = require('./.claude/skills/cfn-redis-coordination/dist/redis-client.js');
const coordinator = new RedisCoordinator();
coordinator.initialize().then(() => {
  console.log('Redis canUseRedis:', coordinator.canUseRedis);
  console.log('Mode:', coordinator.mode);
}).catch(console.error);
"
```

### Key Pattern Reference
```
Coordination Keys:
- swarm:{taskId}:context           - Task context hash
- swarm:{taskId}:{agentId}:done    - Agent completion signal
- swarm:{taskId}:wait              - Waiting coordination list
- swarm:{taskId}:complete          - Task completion flag
- swarm:{taskId}:consensus         - Consensus collection hash
- swarm:{taskId}:results           - Results collection list

Typical Values:
- taskId: UUID or identifier string
- agentId: agent type or identifier
- TTL: 24 hours (86400 seconds) for coordination keys
```

### Emergency Procedures

```bash
# If Redis is completely unresponsive:
# 1. Restart Redis service
docker-compose restart redis
# OR
systemctl restart redis

# 2. Check for corrupted data
redis-cli --scan --pattern "*" | wc -l

# 3. Emergency key cleanup (last resort)
redis-cli FLUSHDB  # ⚠️ DELETES ALL DATA
```

## Success Metrics

### Diagnostic Accuracy
- **Health check reliability**: 100% accurate Redis status reporting
- **Key inspection completeness**: All coordination keys examined
- **Performance analysis accuracy**: Real-time metrics with <5% error margin

### Troubleshooting Effectiveness
- **Issue identification time**: <2 minutes for common problems
- **Resolution success rate**: >90% for coordination issues
- **Data recovery rate**: >95% for recoverable coordination state

### Operational Safety
- **Dry-run mode**: All destructive operations support dry-run first
- **Backup verification**: Verify Redis backups before major operations
- **Rollback capability**: Documented rollback procedures for all changes
