pre-commit-docs

To keep CLAUDE.md and documentation in sync before a git commit, use a pre-commit validation flow that analyzes staged changes across API, config, and module boundaries to detect discrepancies and produce minimal doc updates automatically.

Project reference documentation drifts out of date because staged code modifications are not automatically mapped to their corresponding documentation targets. Validating specific CLAUDE.md sections against the codebase before finalizing commits prevents this stale guidance.

To verify CLAUDE.md architecture and API sections match the current codebase, run a targeted verification check that compares modules, tech stack, configuration, and patterns against staged changes, flagging only contradictory or missing information for update.

Pre-commit documentation checking works for API and config scaling changes by detecting modified code paths in those areas, determining which docs need updates, and applying only the precise corrections required to maintain project synchronization.

The best way to enforce minimal documentation updates on git commit is running a PreToolUse hook that maps changed code areas to specific documentation targets, ensuring only sections with actual discrepancies are rewritten instead of entire files.

You can manually invoke documentation synchronization as a fallback invocation if the automatic pre-commit hook does not run, ensuring staged changes are still analyzed for documentation and CLAUDE.md reference discrepancies before finalizing.
