Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There is a single optional parameter whose schema description coverage is 100% ('Página (por defecto 1)'), so the schema already documents it. The description adds no page-size, ordering, or filtering semantics beyond what the schema provides, making the baseline 3 appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
