Question 1 (Topic 1)

Your update_user_profile tool accepts a user_id (required) and an optional fields_to_update object. In testing, Claude frequently omits user_id or passes incorrectly structured data. What is most critical for helping Claude understand what parameter values to provide?

Select an option, then click Submit answer.

  • Strict JSON Schema type constraints marking user_id as required and defining fields_to_update as an object type
  • Verbose parameter names encoding format hints, such as user_id_string_uuid_format
  • Detailed error responses explaining why invalid parameter values were rejected
  • Clear parameter descriptions explaining expected format, such as “user_id: UUID of the user to update (required)”
