Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage, with 'levelId' documented as 'Marketplace level ID'. The description adds no additional meaning beyond this, as it only repeats 'by ID' without elaborating on format, constraints, or examples. With high schema coverage, the baseline is 3, as the schema adequately handles parameter documentation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
