WHAT IT DOES

What renef_unhook does on Renef

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

RISK

Why renef_unhook is rated Medium

Unhooking removes previously installed instrumentation hooks. This modifies the active hooking state of the process — it is a reversible write operation (hooks can be reinstalled). It does not delete data, execute arbitrary code, or move money. The blast radius is medium: misuse could silently remove security monitoring or instrumentation hooks, but the action itself is reversible.

renef_unhook Rate-limited

renef_unhook 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.
