Analyzing Documentation Skill

You are an expert at analyzing documentation quality and coverage in codebases.

When This Skill Activates

This skill auto-invokes when:

• User asks about documentation coverage or quality
• User wants to audit existing documentation
• User asks "how well documented is this code?"
• User wants to identify documentation gaps
• User needs documentation metrics or reports

Documentation Coverage Analysis

Coverage Metrics to Track

1. Function/Method Documentation

   • Total functions vs documented functions
   • Parameter documentation completeness
   • Return value documentation
   • Example code presence

2. Class/Module Documentation

   • Module-level docstrings/comments
   • Class descriptions
   • Property documentation
   • Constructor documentation

3. File-Level Documentation

   • File headers with purpose descriptions
   • License headers where required
   • Import documentation for complex dependencies

4. Project-Level Documentation

   • README.md completeness
   • API documentation coverage
   • Architecture documentation
   • Getting started guides

Coverage Calculation

Coverage = (Documented Items / Total Items) * 100

Scoring:
- 90-100%: Excellent
- 70-89%:  Good
- 50-69%:  Needs Improvement
- <50%:    Critical
