WHEN AI AGENTS USE THIS TOOL

AI agents call supported_languages to perform operations in Semgrep. 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 SUPPORTED_LANGUAGES

Applying a policy to supported_languages 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.
