Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 100% coverage for the only parameter 'id', but the description adds nothing about it. More critically, the schema shows additionalProperties: false, implying no body fields, but a PATCH update typically expects updatable properties. The description does not clarify what can be updated, so the parameter semantics are incomplete.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
