Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage, with the parameter 'collection' clearly documented as 'Collection name'. The description adds no additional meaning beyond this, such as examples or constraints, but since the schema provides adequate information, the baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
