Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description provides excellent parameter semantics that fully compensate for the 0% schema description coverage. It explains each of the 8 parameters with Korean names, English translations, format examples, and default values. The schema only shows parameter names and types, while the description adds crucial context about what each parameter represents (e.g., '시군구코드' = city/county/district code, '5자리' = 5 digits) and how to format them.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
