Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description adds virtually nothing about the two parameters (query, maxMatches). No information about query format, whether maxMatches is optional, its default behavior, or its upper/lower bounds. With 2 undocumented parameters and zero description coverage, the description must compensate but does not.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
