What problem does it solve? It ensures every markdown document in the mj-agent docs tree conforms to the Meta v2.1, Code_Side v1.1, and Agent_Side v1.1 documentation standards before commits or PRs, catching schema violations, broken wikilinks, and format drift early. ## Core Features & Use Cases - Frontmatter schema validation: Runs scripts/check_frontmatter.py to verify required fields (type, summary, owner, created, updated, state, track) and the 4-value track enum. - Wikilink integrity checks: Runs scripts/check_wikilinks.py to confirm internal [[...]] links resolve, with living vs frozen archive path judgment per ADR-011. - Semi-automated OB checks: Reports PASS/FAIL/WARN/SKIP for OB1-OB5 quality dimensions (length, tense, content boundary, summary quality, internal consistency) plus track-specific A1-A14 checks. - Use Case: After editing a GUIDE document in docs/, run this skill to confirm frontmatter passes, all wikilinks resolve, and INDEX.md/CLAUDE.md sync requirements are flagged before opening a PR. ## Quick Start Ask the assistant to validate the documentation in the mj-agent repo by running the doc-validate checks on docs/ and report any FAIL or WARN items.
