Why create_epic is rated Medium
This tool creates new data (an epic record) in ServiceNow, a mission-critical enterprise platform. While creation is reversible (unlike Destructive), the severity is high because an AI agent could create numerous spurious epics, polluting the project management system, causing workflow disruption, and requiring manual cleanup. It modifies shared organizational data without undo in normal circumstances.
From the tool's definition Tool name 'create_epic' and description explicitly states 'Create a new epic' — an irreversible creation operation in ServiceNow. Requires WRITE_ENABLED=true, confirming write capability.
Attacks that exploit this kind of access
The rule that runs create_epic safely

create_epic stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect NowAIKit — ServiceNow AI Toolkit, apply this rule, and every create_epic call is checked against it from then on.
