Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% and the single testId parameter has no description in either schema or description. The phrase 'for a running usability test' loosely implies testId identifies the test, but no format or source is given. Acceptable given the trivial single-param surface, but not enriched.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
