WHAT IT DOES

What renef_server_kill does on Renef

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

RISK

Why renef_server_kill is rated Critical

Killing a server process is an irreversible destructive action — it terminates the running process, which cannot be undone (the server must be manually restarted). This disrupts the dynamic instrumentation/reverse engineering session and any active hooks or memory operations. The blast radius is high as it would terminate all instrumentation activities on the device.
