WHAT IT DOES

What switch_update_set does on NowAIKit — ServiceNow AI Toolkit

AI agents use switch_update_set to create or update resources in NowAIKit — ServiceNow AI Toolkit, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your NowAIKit — ServiceNow AI Toolkit environment.

RISK

Why switch_update_set is rated Medium

Switching the active Update Set changes which customizations are captured and tracked in ServiceNow's change management system. This is a Write operation because it modifies state (the active context) reversibly — the previous Update Set context can be restored.

From the tool's definition Tool description states 'Switch the active Update Set context' — this modifies the active state/context within ServiceNow, which is a reversible configuration change. The [Scripting] tag indicates it affects code/customization tracking.
