How do I test if my network security policy is working?

The skill includes validation commands such as attempting to install a package from a trusted registry versus using curl on an untrusted domain to verify the blocks are active.

How does this skill handle sensitive secrets like API keys?

The skill enforces a security best practice of never storing secrets in sandbox configurations. It provides patterns for using .env.local files and environment variable references instead.

What is the recommended network mode for general development?

The 'Trusted Network Access' mode is the recommended default, allowing Claude to access pre-approved, safe domains like npmjs.org, github.com, and common container registries.

Does this skill protect against prompt injection attacks?

Yes, it mitigates data exfiltration risks from prompt injection by strictly blocking all outbound network traffic that doesn't match your explicit whitelist of trusted domains.

Can I configure this skill to work with a corporate proxy?

Yes, it includes specialized templates for enterprise proxy settings, including HTTP/HTTPS proxy URLs, noProxy lists for internal domains, and system credential handling.
