AI agents call get_all_semester_grades to retrieve information from Qldt Hanu without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves academic records (grades) without modifying, deleting, or executing operations. It is a read-only query of personal educational data. Severity is medium rather than low because unauthorized access to grades could harm student privacy and enable identity fraud or impersonation within the academic system, though the tool itself does not create financial obligations or permanently damage data.
From the tool's definition Tool name 'get_all_semester_grades' and description 'Get all semester grades' indicate a retrieval operation with no modification of data. The requirement to be logged in first suggests this accesses authenticated student records.
