Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. The description only adds meaning for one parameter (queue_rank: null explicitly un-ranks). The other seven parameters (body, slug, tags, title, pinned, status, post_id) receive no semantic clarification beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
