How does it determine if documentation is outdated?

The skill analyzes recent Git commits and file diffs. If core logic or API endpoints have changed but the corresponding documentation files haven't been updated recently, it flags a potential gap.

Does this skill automatically update my documentation files?

No, this skill is designed for read-only analysis. It generates a comprehensive report of gaps and recommendations, which you can then use to guide updates manually or with other documentation tools.

Which programming languages and frameworks does it support?

It is language-agnostic but includes optimized search patterns for popular frameworks like Django, FastAPI, Express, React, and Vue to better identify components.

Can I use this for API documentation specifically?

Yes, it specifically scans for OpenAPI/Swagger specs and identifies new routes or schema changes that haven't been reflected in your markdown or YAML docs.

Learning & Documentation

Audits code repositories to identify documentation gaps and assess the impact of recent code changes on technical guides.

The Documentation Analyzer is a specialized skill for Claude Code that automates the auditing of project documentation. By scanning git history, cataloging markdown files, and analyzing code changes—such as new API endpoints, data models, or UI components—it detects missing, outdated, or inconsistent information. It generates structured reports with severity-based prioritization, helping developers maintain high-quality, synchronized documentation that accurately reflects the current state of their codebase without manual cross-referencing.
