WHY IT NEEDS A POLICY

Why update_teacher_role needs a policy

This tool modifies teacher role records but does not delete them or execute arbitrary code. Updates are reversible through subsequent modifications, placing it in the Write category. Severity is medium because unauthorized role changes could grant unintended permissions or access to educational resources, but the impact is limited to a single teacher's role configuration and is remediable.

From the tool's definition Tool name 'update_teacher_role' and description 'Update a teacher role' indicate modification of existing data. The 'update' verb confirms this is a Write operation that changes teacher role properties reversibly.
