WHAT IT DOES

What remove_user_from_group does on NowAIKit — ServiceNow AI Toolkit

AI agents call remove_user_from_group to permanently remove resources in NowAIKit — ServiceNow AI Toolkit, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why remove_user_from_group is rated Critical

Removing a user from a group revokes their access and permissions, which is a destructive action from an access-control perspective. While technically data could be re-added, unauthorized removal can immediately break access for users and is difficult to detect/reverse quickly, placing it closer to Destructive than Write. The blast radius is high given potential security and operational impact.

From the tool's definition 'Remove a user from a group' — removal of group membership is an irreversible access-control change that cannot easily be undone; requires WRITE_ENABLED=true
