What types of vulnerabilities does this skill detect?

It detects major security flaws including SQL Injection, Command Injection, XSS, hardcoded secrets, unsafe deserialization, and path traversal risks.

Is it specific to one programming language?

While the examples focus on Python and JavaScript/React, the logic applies to any modern web development stack vulnerable to these patterns.

How does it handle API keys and passwords?

The skill identifies hardcoded credentials and suggests moving them to environment variables or dedicated secret management services.

Can it help with network and API security?

Yes, it flags missing timeouts in HTTP requests and broad exception handling that could mask critical network failures or security breaches.

Does it only identify bugs or does it provide fixes?

It provides both the detection of vulnerable code patterns and specific, copy-pasteable examples of safe, secure implementation alternatives.

Security & Testing

Identifies and blocks common security vulnerabilities while suggesting secure coding alternatives and best practices.

The Security Patterns skill for Claude Code acts as an automated security auditor, providing real-time detection of high-risk vulnerabilities like SQL injection, XSS, and hardcoded secrets. It categorizes code risks into critical blocks and warning flags, offering immediate safe alternatives to ensure production applications remain secure. This skill is essential for developers looking to implement robust security logic and prevent common attack vectors during the development lifecycle.
