Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage, with 'dataset_id' documented as 'Dataset ID or username~dataset-name'. The description adds no additional meaning beyond this, such as examples of valid IDs or how to resolve conflicts. With high schema coverage, the baseline score of 3 is appropriate, as the schema already provides adequate parameter semantics.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
