Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It mentions 'by ID' which clarifies the purpose of the productIds parameter, adding some semantic value. However, it doesn't explain the format of IDs, whether they must exist, or any constraints on batch size. With one parameter and partial clarification, this meets the baseline for adequate but incomplete documentation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
