Scanning For Xss Vulnerabilities
This skill empowers Claude to proactively identify and report XSS vulnerabilities within your codebase. By leveraging advanced detection techniques, including context-aware analysis and WAF bypass testing, this skill ensures your web applications are resilient against common XSS attack vectors. It provides detailed insights into vulnerability types and offers guidance on remediation strategies.
Install
/plugin marketplace add jeremylongshore/claude-code-plugins-plus-skills
/plugin install xss-vulnerability-scanner@claude-code-plugins-plusRun these inside Claude Code. The skill comes with its plugin.
What this skill does
This skill enables Claude to automatically scan for XSS (Cross-Site Scripting) vulnerabilities in code. It is triggered when the user requests to "scan for XSS vulnerabilities", "check for XSS", or uses the command "/xss". The skill identifies reflected, stored, and DOM-based XSS vulnerabilities. It analyzes HTML, JavaScript, CSS, and URL contexts to detect potential exploits and suggests safe proof-of-concept payloads. This skill is best used during code review, security audits, and before deploying web applications to production.
Trigger phrases
Claude loads this skill automatically when you say things like:
How it works
- Code Analysis: The plugin analyzes the codebase, identifying potential XSS vulnerabilities across different contexts (HTML, JavaScript, CSS, URL).
- Vulnerability Detection: The plugin detects reflected, stored, and DOM-based XSS vulnerabilities by injecting various payloads and analyzing the responses.
- Reporting: The plugin generates a report highlighting identified vulnerabilities, their location in the code, and recommended remediation steps.
When to use it
- Perform a security audit of your web application.
- Review code for potential XSS vulnerabilities.
- Ensure compliance with security standards.
- Test the effectiveness of your Content Security Policy (CSP).
- Identify and mitigate XSS vulnerabilities before deploying to production.
Best practices
- Content Security Policy (CSP): Implement a strong CSP to restrict the sources from which the browser can load resources, mitigating the impact of XSS vulnerabilities.
- Regular Updates: Keep your web application framework and libraries up to date to patch known XSS vulnerabilities.

Scanning Input Validation Practices
jeremylongshore/claude-code-plugins-plus-skills
This skill enables Claude to automatically scan source code for potential input validation vulnerabilities. It identifies areas where user-supplied data is not properly sanitized or validated before being used in operations, which could lead to security exploits like SQL injection, cross-site scripting (XSS), or command injection. Use this skill when the user asks to "scan for input validation issues", "check input sanitization", "find potential XSS vulnerabilities", or similar requests related to securing user input. It is particularly useful during code reviews, security audits, and when har
