WHAT IT DOES

What codebrain_init does on CodeBrain

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

WHY IT NEEDS A POLICY

Why codebrain_init needs a policy

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

Verdict

codebrain_init Rate-limited

codebrain_init 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.
