Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, and the schema is an empty object, so schema coverage is complete. The description's mention of 'profile and configuration settings' provides context for what the tool operates on, but with no parameters to explain, the baseline of 4 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
