Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents job_id, every override field, the subject enum, and the assessment_date caveat. The description only restates the override group at a high level ('optionally override the detected identity (title/subject/board/year)'); it notably omits assessment_date from that list and adds no formatting detail beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
