Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is low (only 'query' is described), and the description does not explain 'sort', 'type', or 'limit' beyond what the enums already self-document. The URL guidance concerns response fields, not input parameters, so it does not compensate for the schema's low descriptive coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
