Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is only 20% across 5 parameters (nested answers object), so the description must carry the load. It clarifies only provider_hint ('only for an explicitly named company'); user_intent, idempotency_key, and the answers sub-fields (brand, model, zip_code, appliance_type, problem_description) get no added meaning beyond their bare schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
