What problem does it solve? Broken skill layouts — a missing SKILL.md, a mismatched name: field, a nested skill, or a catalog row that no longer matches the source tree — abort the build and block pull requests. This skill reports every such problem at once, read-only, so the tree can be fixed before building or before CI fails. ## Core Features & Use Cases - Layout validation: Detects non-directory entries, missing SKILL.md files, nested skills, and folder names that violate the hos-<name> naming pattern. - Frontmatter checks: Reports missing name: fields and name values that disagree with the folder name. - Catalog consistency: Compares docs/skills.md and docs/skills.ja.md tables and boundary bullets against the actual skills under kit/skills/, in both directions. - Use Case: Before opening a pull request that adds or renames a skill, run the audit to list every layout and catalog problem in one report instead of discovering them one build failure at a time. ## Quick Start Ask the agent to run the audit skill to check every skill under kit/skills/ and report any layout or catalog problems before opening the pull request.
