Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description needs to compensate. It partially does by implying that 'query' is a keyword string ('Search ... using keywords'), but it does not mention the 'language' parameter at all. The parameter names and enum/default in the schema help, but the description does not carry enough weight for the low coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
