Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is only 33% (only task_type is documented in the schema), and the description compensates well: it explains query as a free-form semantic search and supplies the actual enum values for task_type, which the schema lacks (0 enums). The 'limit' parameter remains undocumented in both schema and description, keeping it from a 5.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
