Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% for all four parameters, each with a clear definition (URL, host, JSON, timezone). The description adds no relational meaning between these parameters and the classification concept, but the baseline of 3 applies because the schema fully documents the parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
