[Documentation Layer] Documentation Quality & Coverage Analyzer

[gloomcheng]

Problem

No awareness of:

• Missing documentation (JSDoc/TSDoc)
• Outdated docs (code changed, docs didn't)
• Doc coverage (% of public APIs documented)
• Broken code examples in docs

Developer Pain Points

• Don't know what needs documentation
• Docs get out of sync with code
• No validation of doc examples
• Manual doc reviews required

Proposed Solution

Documentation Analyzer with:

1. Check for missing JSDoc/TSDoc
2. Validate code examples in docs
3. Track doc-to-code sync
4. Generate missing doc templates

Features

• Parse JSDoc/TSDoc from source
• Calculate documentation coverage
• Validate code examples (syntax check)
• Detect outdated documentation
• Auto-generate doc templates

MCP Tools

• doc-analyze: Analyze documentation coverage
• doc-missing: Find undocumented code
• doc-validate: Validate doc examples
• doc-generate: Generate missing docs

Priority

Medium

Effort Estimate

Implemented documentation quality & coverage analyzer with 4 MCP tools:

• doc-analyze: Analyze documentation coverage and quality metrics
• doc-missing: Find undocumented or partially documented code
• doc-validate: Validate code examples in @example blocks
• doc-generate: Generate JSDoc/TSDoc templates for missing docs

Features:

• Parse JSDoc/TSDoc from TypeScript/JavaScript source files
• Calculate coverage metrics by entity type (class, interface, function, etc.)
• Quality scoring (0-100) and ratings (excellent/good/fair/poor)
• Priority sorting for public API documentation
• Template generation with TODO placeholders
