Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one required parameter ('worksheet_name') with 0% description coverage. The description does not explain what 'worksheet_name' means or any constraints (e.g., uniqueness, length). Since there is only one parameter, the baseline is 4, but the description adds no value beyond the schema, so a 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
