# Knowledge Base Skill (Mega-Skill)

**Version:** 1.0.0
**Purpose:** Organizational learning from CFN Loop execution
**Status:** Production
**Consolidates:** workflow-codification, cfn-playbook
**Confidence:** 7.0/10 (dual learning systems)

---

## Overview

This mega-skill provides organizational learning:
- **Workflow** - Track edge cases, failures, cost metrics, ROI
- **Playbook** - Store successful patterns, agent configs, iteration strategies

---

## Learning System

- **Successes** → Playbook (what worked)
- **Failures** → Workflow codification (what to avoid)
- Combined: Complete organizational memory

## Usage

### Main Entry Point
```bash
# Initialize databases
./execute.sh init

# Query for patterns
./execute.sh query 'authentication'

# Store new learning
./execute.sh store playbook '{"task_type": "auth", "pattern": "..."}'

# Show help
./execute.sh help
```

### Advanced CLI Usage
```bash
# Direct CLI access
./cli/knowledge-base.sh --help

# Query workflow patterns
./cli/knowledge-base.sh query-workflow --pattern 'auth'

# Query playbook entries
./cli/knowledge-base.sh query-playbook --task-type bugfix

# Store learning with metadata
./cli/knowledge-base.sh store-learning \
  --type workflow \
  --category edge-case \
  --data '...' \
  --confidence 0.85
```
