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 partially explains the 'dialogue' parameter format but omits the 'user_id' parameter entirely. The explanation of 'dialogue' as '[role, content]' maps to the schema, but lacks depth (e.g., allowed roles or content types). Insufficient for an agent to correctly construct the arguments.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
