Does this skill provide a security score?

Yes, it generates a detailed report that includes a numerical score and a letter grade based on the strength of the site's header configuration.

Is this a replacement for a full penetration test?

While effective for header analysis, it should be used as one component of a broader security strategy including unit testing and code audits.

Which headers are checked by this skill?

The skill evaluates critical security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Content-Type-Options, and X-Frame-Options.

How does the Security Headers Analyzer work?

It fetches the HTTP response headers of a specified URL and compares them against security best practices to identify misconfigurations.

Can I use this for local development sites?

This skill requires the URL to be reachable via WebFetch, so it works best on publicly accessible domains or staging environments.
