Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 50%, and the description adds zero parameter-level information. However, each parameter inside the nested 'data' object has its own description (tags, type, field, degree, etc.). The id parameter is described as 'エントリID (UUID)' and data as an object type. The description adds nothing beyond schema, but the schema itself documents parameters reasonably, so a baseline-adjacent score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
