# CFN Redis Data Extraction Skill

## Purpose

Extracts complete Redis coordination data from completed CFN Loop tasks and structures it into comprehensive JSON files for analysis, auditing, and performance tracking.

## When to Use

- **Mandatory**: Execute after each completed CFN Loop task
- **Timing**: After Product Owner decision, before Redis cleanup
- **Trigger**: Main Chat coordination after loop completion
- **Scope**: All Redis keys for a specific task ID

## Usage

```bash
# Extract data from completed CFN Loop
npx claude-flow-novice skill cfn-redis-data-extraction --task-id "cfn-cli-XXXXXXX-XXXXX"

# Extract with custom output directory
npx claude-flow-novice skill cfn-redis-data-extraction \
  --task-id "cfn-cli-XXXXXXX-XXXXX" \
  --output-dir "./analysis/loop-data"

# Extract multiple tasks
npx claude-flow-novice skill cfn-redis-data-extraction \
  --task-ids "cfn-cli-XXXXXXX-XXXXX,cfn-cli-YYYYYYY-YYYYY"

# Extract with detailed performance metrics
npx claude-flow-novice skill cfn-redis-data-extraction \
  --task-id "cfn-cli-XXXXXXX-XXXXX" \
  --include-performance=true
```

## Implementation

```bash
#!/bin/bash

## Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `--task-id` | string | Yes | Single CFN Loop task ID to extract |
| `--task-ids` | string | No | Comma-separated list of task IDs |
| `--output-dir` | string | No | Output directory (default: ./analysis/cfn-loop-data) |
| `--include-performance` | boolean | No | Include Redis performance metrics |
| `--verbose` | boolean | No | Enable verbose output |

## Output Structure

The skill generates two files per task:

### 1. Main JSON Data File
`cfn-loop-{task_id}-extracted.json`

```json
{
  "task_id": "cfn-cli-543042-13483",
  "extraction_timestamp": "2025-11-09T04:56:00Z",
  "extraction_version": "1.0.0",
  "redis_keys_analyzed": 44,
  "agents": {
    "cfn-v3-coordinator-1": {
      "agent_type": "coordinator",
      "loop": "coordination",
      "confidence": 0.85,
      "completion_signal": "complete",
      "messages": [...],
      "result": "..."
    },
    "agent-id-2": {
      "agent_type": "frontend-developer",
      "loop": "3",
      "confidence": 0.92,
      "completion_signal": "complete"
    }
  },
  "metadata": {
    "task_context": "...",
    "performance": {
      "redis_memory_usage": "2.5M",
      "redis_connected_clients": 12
    }
  },
  "summary": {
    "total_agents": 11,
    "completion_signals": 11,
    "average_confidence": 0.86,
    "extraction_status": "success"
  }
}
```

### 2. Summary Text File
`cfn-loop-{task_id}-summary.txt`

Human-readable summary with key statistics and agent information.

## Integration Points

### CFN Loop Completion Workflow
```bash
# After Product Owner decision, before Redis cleanup
./.claude/skills/cfn-redis-data-extraction/extract.sh \
  --task-id "$TASK_ID" \
  --output-dir "./analysis/loops" \
  --include-performance=true

# Then proceed with Redis cleanup
redis-cli DEL "cfn_loop:task:$TASK_ID:*" "swarm:$TASK_ID:*"
```

### Main Chat Automation
```bash
# Automatic extraction after loop completion
npx claude-flow-novice skill cfn-redis-data-extraction \
  --task-id "cfn-cli-XXXXXXX-XXXXX" \
  --verbose
```

## Error Handling

- **Redis Unavailable**: Graceful exit with error message
- **No Keys Found**: Warning message, continue processing
- **Invalid JSON**: Fallback to basic text extraction
- **Permission Issues**: Directory creation with appropriate permissions

## Performance Considerations

- **Large Key Sets**: Processes keys in batches to avoid memory issues
- **Concurrent Access**: Uses read-only Redis operations
- **File Size**: JSON files are compressed and structured efficiently
- **Extraction Time**: Typically <5 seconds per task

## Validation

The skill includes built-in validation:
- Redis connectivity check
- JSON structure validation
- Data completeness verification
- Output file creation confirmation

## Maintenance

- **Version Tracking**: Each extraction includes version metadata
- **Backward Compatibility**: Supports multiple extraction formats
- **Cleanup**: Old files can be archived or cleaned up automatically
- **Monitoring**: Integration with system monitoring for extraction success rates
