What problem does it solve? Keeping a multi-plugin repository's documentation in sync with its skills and agents is error-prone: long-form docs drift from SKILL.md frontmatter, indexes miss new entities, and cross-references break after renames. This skill automates that audit so every doc stays accurate after changes. ## Core Features & Use Cases - Branch-scoped or full-sweep audits: On a feature branch it audits only entities the branch touched; on the default branch it sweeps every skill, agent, index, and root doc. - Source-of-truth verification: Reads each SKILL.md or agent file first, then checks the long-form doc, index entries, and CLAUDE.md catalog against it, treating contradictions as functional bugs. - Cross-reference and bidirectional-link checks: Verifies sibling boundary statements, Related documentation pairings, and count-free references in README and concepts docs. - Use Case: After renaming a skill on a feature branch, run the skill to update the skill's long-form doc, the skills index, the CLAUDE.md catalog, and every sibling doc that referenced the old name. ## Quick Start Ask the assistant to run /han-update-documentation to audit and refresh the Han plugin docs for the changes on the current branch.
