Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the schema provides no parameter descriptions. The description adds basic semantics by listing parameters with brief explanations (e.g., '用户的JSESSIONID' for JSESSIONID, '课程ID' for course_id), which helps clarify what each parameter represents. However, it doesn't provide format details, constraints, or examples, leaving gaps in understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
