What problem does it solve? Documentation drifts out of sync with code as implementations change, leaving READMEs, docstrings, and API specs describing functions, flags, and endpoints that no longer exist. This Skill compares repository documentation against the actual implementation, detects every divergence, and updates the docs to match the code. ## Core Features & Use Cases - Divergence Detection: Scans Markdown files, docstrings, OpenAPI/Swagger specs, and example config files, then cross-checks them against real function names, CLI flags, API endpoints, and config keys in the code. - Bulk Auto-Update: Applies all detected fixes in one pass while preserving the original language, style, and formatting of each document. - Dry-Run Preview: The --dry-run flag reports detected divergences with before/after previews without modifying any files. - Use Case: After renaming CLI flags and adding a required API field, run the Skill on the repo to find every stale reference in README.md and docs/api.md and rewrite them to match the current implementation. ## Quick Start Ask the AI to check the repository documentation against the current implementation and update any outdated sections, optionally with --dry-run to preview changes first.
