WHEN AI AGENTS USE THIS TOOL

AI agents call config_helper to perform operations in CircleCI. While the risk category is not fully classified, applying a rate limit gives you visibility into how often the tool is called and prevents unexpected bursts of activity from autonomous agents.

WHY ENFORCE A POLICY ON CONFIG_HELPER

Applying a policy to config_helper gives you an audit trail of every call an AI agent makes. Even for low-risk tools, visibility into agent behaviour helps you debug issues, optimise workflows, and maintain compliance with your organisation's security requirements.

RECOMMENDED POLICY

Apply a rate limit to control usage and monitor for unexpected behaviour.

circleci.yaml 
tools:
  config_helper:
    rules:
      - action: allow
        rate_limit:
          max: 60
          window: 60
