Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the single parameter courseId is self-explanatory and the description reinforces it by saying the course is retrieved 'by ID'. No additional format, source, or usage semantic is provided, but none is strictly needed for this simple parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
