Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage and no enums or required fields. The description mentions example fields (type, value, due_date) and hints that `extra` holds additional official API fields, and 'receita ou despesa' gives a clue about type values. However, it does not explain formats for value/due_date, constraints, or how extra merges with named fields.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
