Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema defines zero properties and allows arbitrary additional properties, so the schema itself provides no parameter documentation. The description does not compensate by explaining what parameters the tool expects (e.g., pan value, clip identifier). Schema coverage is technically 100% because there are no properties, but this is meaningless without parameter descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
