Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description carries full responsibility for parameter meaning. It maps 'valor' to value, 'vencimento' to due_date, and 'status' to status, explicitly names 'extra' for additional fields, and mentions 'ids' for bulk. It also implies that id is the required identifier. This fully compensates for the schema's lack of descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
