Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero parameters, making parameter semantics irrelevant. Since there are no parameters to explain, the baseline for a 0-parameter tool is 4, and the description does not need to add parameter-level detail. However, the description also does not help contextualize the tool's purpose, which would be beneficial even with no parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
