Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description itself adds little parameter-level guidance, but schema description coverage is 100% and each parameter, including body, comment_id, task, workspace, and context, has a schema description. Therefore the schema carries the parameter semantics; the description does not need to compensate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
