AI agents call get_teacher_role to retrieve information from Eduframe without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about a teacher role from the Eduframe API. It performs a simple data lookup with no state changes, side effects, or irreversible actions. The blast radius of misuse is minimal—an attacker could only view teacher role information that may already be accessible through other means. This is a straightforward Read category tool with low severity.
