How does git-derive-docs find undocumented features?

It analyzes commit messages tagged as 'feat', large directory additions, and coordinated multi-file changes, then cross-references them with existing files in your documentation directories to find gaps.

Can I use this on a specific branch or time period?

Yes, you can use the --since= flag to analyze commits after a specific date or --depth= to limit the number of commits scanned.

Will it automatically overwrite my existing files?

No. The skill is designed to find gaps and suggest new documents. You can also use the --dry-run flag to see a report of findings without any files being created.

What is the benefit of deriving .claude/rules?

By deriving rules from your actual commit history and file structures, Claude can better understand and adhere to your project's specific naming conventions, tool configurations, and testing patterns.

학습 및 문서화

Analyzes Git commit history to automatically surface and generate missing documentation, architectural decisions, and project rules.

This skill scans your repository's Git history to identify documentation debt—features, architectural shifts, and coding conventions that were implemented but never officially documented. By parsing commit patterns, file changes, and naming conventions, it can automatically draft Product Requirement Documents (PRDs), Architecture Decision Records (ADRs), and .claude/rules files. It helps maintain a clean, well-documented codebase by closing the gap between implementation and documentation, ensuring that the rationale behind every major change is preserved for future development and team onboarding.
