Agent Skill — Development skill for Claude Code

ast-grep Plugin Marketplace for AI Agents

A Claude Code plugin marketplace containing the ast-grep skill for powerful structural code search using Abstract Syntax Tree (AST) patterns. Search your codebase based on code structure rather than just text matching.

What is This?

This is a **Claude Code plugin marketplace** that provides the **ast-grep plugin**. The plugin includes a skill that teaches Claude how to write and use ast-grep rules to perform advanced code searches. Unlike traditional text-based search (grep, ripgrep), ast-grep understands the structure of your code, allowing you to find patterns like:

• "Find all async functions that don't have error handling"
• "Locate all React components that use a specific hook"
• "Find functions with more than 3 parameters"
• "Search for console.log calls inside class methods"
