 title: "AutoGrep: Automated Generation and Filtering of Semgrep Rules from Vulnerability Patches"
 ---
-## Abstract
-
 This article presents [AutoGrep](https://github.com/lambdasec/autogrep), an automated system for generating and filtering high-quality security rules for static analysis tools. Motivated by recent licensing changes in the Semgrep ecosystem, AutoGrep addresses the critical need for maintaining and expanding permissively licensed security rules. By leveraging Large Language Models (LLMs) and a multi-stage filtering pipeline, AutoGrep transforms vulnerability patches into precise, generalizable security rules while eliminating duplicates and overly specific patterns.
