About
The Security Fixer skill serves as an automated security engineer within Claude Code, specializing in the remediation of critical vulnerabilities across various programming languages and frameworks. It transforms security triage findings into production-ready patches using the unified diff format, ensuring that fixes are minimal, secure by default, and backward-compatible. By applying industry-standard patterns for SQL injection, cross-site scripting (XSS), and weak cryptography, this skill helps developers accelerate their remediation workflows while maintaining code quality and functional integrity through structured validation and testing guidance.
