type:audit

Audit a website's HTTP security headers and cookie flags — CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP/COEP, version-leaking banners, and Secure/HttpOnly/SameSite cookies. Use when the user asks to "check my site's security headers", "audit HTTP headers", "is my CSP/HSTS configured right", or "scan a URL for header misconfigs".

From the source SKILL.md

Checks a site's response headers against modern web-security best practices and returns prioritized findings with concrete fixes. The analysis core is pure and offline-testable; live scanning uses only Python's stdlib urllib.
