Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has one parameter, exerciseTemplateId (string), with no description. The phrase 'by its id' clarifies that this parameter is the identifier of the exercise template, adding some meaning beyond the raw schema. However, it does not explain how to obtain the ID, whether it should be a UUID or any other format, or any validation rules. Given the schema coverage is 0%, the description partially compensates but not fully.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
