查询教师的课程组
AI agents call query_teacher_groups to retrieve information from Xiaoya Teacher without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves course group information for a teacher without any capability to modify, delete, or execute side effects. It is a straightforward data lookup operation typical of educational management systems. The low severity reflects minimal risk if misused by an AI agent—it can only expose teacher course group data, not alter it or trigger external actions.
