Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% for the single optional 'limit' parameter, with minimum, maximum, default, and cap explanation already present. The description does not need to repeat parameter details, so a baseline 3 is appropriate. It adds no new parameter-specific semantics but does not need to.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
