Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 77%, and several parameters have individual descriptions (request_id, clinic_id, patient_ref, chief_complaint). The tool description does not add parameter-specific detail, but the baseline 3 applies because the schema handles most parameter semantics. 'No-memory' hints at request-scoped data but not tied to any parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
