Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description carries the burden of explaining parameters, but it mentions none. Property names like subject, message, order_id, and confirmation_id are somewhat self-explanatory, but the description does not clarify which fields are required, how they relate, or when the optional identifiers should be supplied.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
