WHAT IT DOES

What rc_compound does on RC Engine

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

WHY IT NEEDS A POLICY

Why rc_compound needs a policy

An AI agent can call rc_compound faster than any human can review — one bad instruction and it creates or modifies resources in RC Engine by the hundred, each call as confident as the last.

Verdict

rc_compound Rate-limited

rc_compound 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.
