Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is only 20%, so the description must compensate. It does explain the purpose of user_intent (complete intent) and provider_hint (only when named), and hints at answers via 'every public service detail already stated'. However, it does not clarify idempotency_key or the structure of nested answers beyond what the schema keys show. The description adds some meaning but leaves gaps for agents.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
