## Frequently Asked Questions

### How does the Cloudflare security audit skill work?

It executes a multi-phase static inspection checking for hardcoded credentials, unchecked query parameters, missing auth guards, and insecure CORS headers.

### Can these skills prevent API key leaks?

Yes. They instruct agents to verify that sensitive tokens remain exclusively in environment variables and never get committed to client-side bundles.
