Skills Analyzer

When to Use

This is Step 1 of the refactoring workflow:

1. analyze ← You are here
2. extract → Run after analysis identifies issues
3. validate → Run after extraction completes

Workflow

Step 1: Scan Skills

Locate all SKILL.md files in .claude/skills/ or ~/.claude/skills/.

Step 2: Check Issues

For each SKILL.md, check lint rules (frontmatter, content, naming, reference, security).

Rule details: references/lint-rules.md

Step 3: Detect Duplicates

Compare content across all SKILL.md files for exact (100%), near (≥80%), or structural duplicates.

Detection patterns: references/duplicate-patterns.md

Step 4: Calculate Quality Score

Score = 100 - (Errors × 10) - (Warnings × 5) + Bonus (max 100)

Score details: references/lint-rules.md#quality-score-calculation

Output

# Analysis Report
