Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It mentions 'expected text' and implies a mode via 'exact', but does not explain the meaning of the 'exact' parameter (e.g., that false means contains). The default value is not clarified, and there is no additional semantic detail beyond what the parameter names hint.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
