How does it handle Content Security Policy (CSP)?

The skill provides compliant CSP strings that adhere to MV3's restriction against remote code execution and unsafe-eval.

Can I use this for Edge or Brave extensions?

Yes, because Edge and Brave are Chromium-based, the Manifest V3 standards provided by this skill are largely compatible across those browsers.

What are the biggest changes in Manifest V3 covered by this skill?

This skill covers the shift from persistent background pages to ephemeral service workers, the new declarativeNetRequest API, and stricter Content Security Policies.

Does this skill help with Manifest V3 permissions?

Yes, it provides a full reference of API permissions and host permissions, which are now separated in the MV3 specification for better security.
