Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must compensate. It adds some meaning by explaining that 'job_id' identifies a single job and 'all_jobs' deletes the whole queue. However, it does not detail the types (string, boolean) or behaviors (e.g., required vs optional), which are partly in the schema. The added value is moderate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
