Is this a replacement for a full penetration test?

No, this is a targeted tool for header configuration. It should be used as one part of a broader security strategy alongside other vulnerability scanners and code audits.

Can it help fix the issues it finds?

Yes, the report includes specific recommendations and implementation examples that you can use to resolve identified security gaps.

What headers does this skill analyze?

It checks for critical security headers including Content-Security-Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.

How does the grading system work?

The skill evaluates headers based on industry-standard security benchmarks, assigning a score and grade based on the presence, configuration, and effectiveness of your security headers.

Can I use this for internal development URLs?

As long as the URL is accessible via the WebFetch tool from Claude's environment, it can analyze the headers and provide a report.

安全与测试

Evaluates HTTP security headers of any domain to identify vulnerabilities and provide actionable hardening recommendations.

The Security Headers Analyzer is a specialized Claude Code skill designed to strengthen web application security by auditing HTTP response headers. It automatically fetches headers from a target URL, evaluates them against industry best practices—including HSTS, CSP, and X-Frame-Options—and generates a comprehensive report featuring a security grade and prioritized improvement steps. This skill is an essential tool for developers and security engineers performing rapid audits, ensuring compliance with web security standards, and mitigating risks like Cross-Site Scripting (XSS) and clickjacking.
