Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description has to carry the load. It explains publish_at (ISO date-time or 'next_slot') and the conditional use of integration_id well, and implies article_id. The required idempotency_key is never mentioned, leaving one of four parameters undocumented anywhere.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
