Does it support my programming language?

Yes, it automatically detects your stack and supports C/C++, Python, JavaScript, Java, Go, Ruby, PHP, Rust, and more.

Does it integrate with other security frameworks?

Yes, every finding is cross-referenced with OWASP Top 10 categories, STRIDE threat modeling letters, and MITRE ATT&CK techniques.

Can it help me fix the security issues it finds?

Absolutely. By using the --fix flag, the skill provides inline code suggestions to remediate identified vulnerabilities directly within your workflow.

How does it handle false positives?

The skill performs context analysis, tracing data flows and checking for existing mitigations to ensure findings are relevant and actionable rather than just simple pattern matches.

What is the SANS/CWE Top 25 skill?

It is a security analysis tool for Claude Code that scans your project for the 25 most dangerous software weaknesses as defined by SANS and MITRE.

Security & Testing

Analyzes codebases for the SANS/CWE Top 25 most dangerous software weaknesses to identify and fix critical security vulnerabilities.

The SANS/CWE Top 25 skill is a specialized security dispatcher for Claude Code designed to perform deep vulnerability scans based on the most recent SANS/CWE framework. It automatically detects your project's technology stack—including languages like C++, Python, Java, and JavaScript—to apply relevant security checks for injection, memory safety, authentication, and data handling. Beyond simple pattern matching, it performs context analysis to reduce false positives, ranks findings by severity, and provides cross-references to OWASP and STRIDE, making it an essential tool for developers conducting security audits or preparing for production releases.
