Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, meaning none of the 5 parameters have descriptions in the schema. The tool description adds no parameter information beyond what's implied by 'list test case execution results'—it doesn't explain what 'fqn', 'start_ts', 'end_ts', etc., mean or how they affect the listing. This fails to compensate for the schema gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
