Documentation Sync

概要

Documentation Sync is a specialized tool for maintaining harmony between a project's implementation and its written guides. It treats documentation as 'guilty until proven innocent,' aggressively identifying discrepancies in API signatures, renamed parameters, and broken code examples by comparing them against the ground truth of the working codebase. By analyzing recent git commits for deletions and breaking changes, it helps developers update READMEs, contribution guidelines, and detailed documentation folders whenever code evolves, ensuring that users always have access to functional and accurate instructions.
