Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It adds that matter_id is a 'GUID', which clarifies the expected format beyond the schema's plain string type. However, it does not explain how to obtain the GUID, acceptable value ranges, or uniqueness constraints. The addition is helpful but minimal.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
