Verify that generated documentation stays aligned with the technical implementation and its references. Use this skill whenever the user mentions documentation drift, doc code alignment, stale documentation, broken reference, rfc link, api doc sync, symbol mismatch, or is working with Sphinx, mkdocs, Vale, even if they never say "document alignment validation" explicitly. Routes live lookups through the Code-Documentation-Hygiene-API endpoint. Do not use it for unrelated application feature work or general coding questions.
