Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Both parameters are fully described in the schema (100% coverage). The description adds little beyond the schema, though it reinforces the conditional need for claim_id based on multiple_answers. Since schema already explains when claim_id is needed, the description provides no extra semantic value, so baseline of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
