Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has zero parameters, so the description is not required to document parameters. However, it does not explicitly state that no parameters are needed, missing an opportunity to clarify usage. Baseline for no-param tool is 4, but the omission reduces it.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
