Can I use this for internal enterprise registries?

Yes, it includes specialized configurations for internal registries, custom proxies, and corporate network requirements like private CDNs.

How does this skill prevent prompt injection attacks?

It enforces strict network isolation, ensuring that even if a malicious prompt is processed, the sandbox cannot exfiltrate data to unauthorized external domains.

Does this skill handle my API keys and secrets?

The skill provides a framework for secure management, specifically recommending that secrets are stored in .env.local and never hardcoded in sandbox configurations.

Is it compatible with standard developer tools?

Yes, it includes pre-configured access for major package and container registries including NPM, GitHub, Docker Hub, PyPI, and RubyGems.

What network modes are available?

It supports three modes: Trusted (approved domains only), None (complete network isolation), and Custom (user-defined whitelist).
