Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so the description is not required to explain parameter semantics. The schema is empty and the description adds no parameter-related info, but the baseline for 0 parameters is 4. The description does add context about the output, which is useful but not parameter-specific.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
