Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, and each parameter (limit, scene, titleContains) is documented with enough meaning in the schema itself. The description does not add extra parameter-level semantics, which is acceptable given the baseline of 3 when the schema fully covers the parameter detail.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
