WHAT IT DOES

What delete_actors does on Uefn

AI agents call delete_actors to permanently remove resources in Uefn, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_actors is rated Critical

This tool permanently removes actors from the Unreal Editor for Fortnite project, an action that cannot be undone programmatically. Deletion is irreversible and falls squarely into the Destructive category. High severity reflects the potential for an AI agent to accidentally remove critical game assets or scenes. The confidence is high because the name and description are explicit and unambiguous.

From the tool's definition Tool name is 'delete_actors' and description states 'Delete actors by their labels.' The verb 'Delete' directly indicates irreversible removal of data.
