How do I start a security scan using Claude?

You can trigger the scanner by using the shortcut command '/xss' or by asking Claude to 'scan for XSS vulnerabilities' in a specific file or directory.

Does this skill provide code fixes?

Yes, after identifying a vulnerability, the skill provides a detailed report including the affected code snippet and specific remediation steps, such as using sanitization libraries.

What types of XSS can this skill detect?

This skill is designed to identify the three primary types of Cross-Site Scripting: Reflected, Stored, and DOM-based XSS vulnerabilities.

Can I use this for production security audits?

While highly effective for identifying vulnerabilities during development and staging, it is best used as part of a comprehensive security strategy alongside manual penetration testing.

Which file types does the XSS scanner analyze?

The scanner analyzes web-related files including HTML, JavaScript, CSS, and server-side code that handles URL parameters or user-generated content.
