Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has no parameters (0 params, 100% coverage per schema). With zero parameters, the baseline is 4. The description adds value by detailing the return values (form name, ID, field definitions), which compensates for the absence of parameter documentation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
