Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the Args block fully compensates by explaining every parameter: query length limit, top_k default and max, mode options with plan requirements, document_type example, language format with ISO 639-1 examples, and quality_grade allowed values. This is far more informative than the raw schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
