概要
The Semgrep Rule Creator skill enables developers and security researchers to build, test, and refine custom Semgrep rules with a high degree of precision. By enforcing a strict test-first methodology and utilizing AST (Abstract Syntax Tree) analysis, this skill helps users create robust detectors for both simple bug patterns and complex data flow vulnerabilities using taint mode. It streamlines the entire development lifecycle—from initial pattern identification to final optimization—ensuring that custom rules minimize false positives while maintaining high performance across large codebases.
