Skill Refactor: Meta-Skill for Skill System Evolution

A self-analyzing skill that audits, evaluates, and refactors the entire skill ecosystem.

When to Activate

Use this skill when:

• "Analyze our skills" or "audit skill system"
• "Find redundant content across skills"
• "Score skill atomicity" or "are skills atomic enough?"
• "Map skill dependencies" or "composability graph"
• "Refactor skill architecture"
• Planning skill system evolution

Philosophy

Radical Atomicity: Each skill should do ONE thing exceptionally well.

Composability: Skills are Lego blocks - AI orchestrates them dynamically.

State-Awareness: Skills read live project state, not static snapshots.

Step 1: Discover & Parse Skills

1.1 Find All Skills

import re
from pathlib import Path

    skills = []
    for root, dirs, files in os.walk(skills_dir):

1.2 Parse Skill Metadata

def parse_skill(skill_path):

            if ':' in line:
                key, value = line.split(':', 1)
                frontmatter[key.strip()] = value.strip()

    # Extract structure
    sections = re.findall(r'^#{1,3}\s+(.+)$', content, re.MULTILINE)
    code_blocks = re.findall(r'```\w*\n(.*?)```', content, re.DOTALL)

# Analyze single skill

# Generate skill dependency graph

Example 4: Detect Redundancy

# Find duplicate content
skills = discover_skills()
all_data = [parse_skill(s['path']) for s in skills]
redundancies = detect_redundancy(all_data)

print(f"Found {len(redundancies)} redundancy instances:")

Atomicity Report

📊 Atomicity Scores

🟢 Excellent (90-100):
  - data-cleaning-standards: 95/100
  - field-validation: 92/100

🟡 Good (70-89):
  - vue-component-dev: 78/100 (file too long: 500+ lines)

🔴 Needs Refactoring (<70):
  - analyzing-auto-insurance-data: 45/100
    ⚠️ Multiple topics (data, API, business logic)
    ⚠️ File too long (800+ lines)
    💡 Recommendation: Split into 3 skills:
       - insurance-data-analysis
       - insurance-api-patterns
       - insurance-business-rules

Redundancy Report

🔄 Redundancy Detection

Found 5 instances of duplicate content:

1. Code Duplication
   Skills: data-cleaning-standards ↔ backend-data-processor
   Overlap: 3 code blocks (80%+ similar)
   Sample: "def handle_missing_values(df)..."

2. Section Overlap
   Skills: testing-and-debugging ↔ deployment-and-ops
   Common sections: ["Troubleshooting", "Common Issues"]

💡 Recommendation: Extract to shared "common-patterns" skill

Refactoring Decision Tree

Is atomicity < 70?
├─ Yes → Should split?
│   ├─ File > 500 lines → Split by sections
│   ├─ Multiple topics → Split by domain
│   └─ Too many code blocks → Extract to reference docs
└─ No → Check redundancy
    ├─ >3 redundancies → Extract shared skill
    └─ OK → Check composability
        ├─ Orphan skill → Add references
        └─ OK → Check state-awareness
            ├─ Score < 40 → Replace static content
            └─ OK → ✅ Skill is optimal

🔄 Complete Intelligent Agent Workflow

user_task = "我想优化数据加载性能"

# Step 3: Agent decomposes task

🎯 What Changed in v2.0

Dimension	v1.0	v2.0
Activation	User calls manually	Proactive monitoring
Analysis	5 static layers	7 layers + real-time perception
Output	Analysis report	Actionable recommendations
Learning	None	Persistent memory system
Orchestration	None	Task decomposition engine
State	Analyzes snapshots	Queries live project state
Intelligence	Reactive	Autonomous Agent

Impact: This upgrade transforms the skill system from a "library of documentation" into a self-aware, learning, orchestrating intelligence.
