Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description does not discuss parameters at all, but the input schema contains detailed descriptions for every property (name, rows, state, etc.), including examples and notes. Since schema description coverage is effectively high, the description need not compensate; the schema carries the load, so a baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
