Map the XSS attack surface of a target URL. Analyze security headers, client-side frameworks, JavaScript patterns, and DOM structure to identify what makes XSS possible, easier, or harder.
This skill does NOT inject payloads or test for XSS. It performs passive observation only (HTTP requests + source analysis). For active XSS testing, use /xss-finder.
