Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds no parameter information beyond what the input schema provides, but schema description coverage is 100%, documenting the single optional 'directory' parameter clearly. With only one parameter and high schema coverage, the baseline is strong, and the description doesn't need to compensate. However, it doesn't add extra meaning, such as examples or constraints, keeping it at a baseline level.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
