Is it safe to perform project-wide refactors with this tool?

Yes, ast-grep includes an interactive mode for reviewing changes one-by-one and uses AST logic to ensure variables and code structure are preserved correctly during rewrites.

What is the advantage of ast-grep over standard grep?

Unlike standard grep which uses text or regex, ast-grep understands the code's syntax tree, allowing it to match logical structures like 'all functions with three arguments' regardless of whitespace or formatting.

Which programming languages does this skill support?

It supports a wide range of popular languages including JavaScript, TypeScript, Python, Rust, Go, Java, C++, Ruby, C, and PHP.

Can I use this skill to automatically fix code issues?

Yes, the skill supports rewrite commands and a 'scan' mode using YAML rules that can detect issues and automatically apply fixes across your entire project.

Herramientas para Desarrolladores

Performs precise structural code searches and automated refactors using Abstract Syntax Tree (AST) patterns across multiple programming languages.

This skill integrates the power of ast-grep into Claude Code, enabling sophisticated code manipulation that transcends simple text-based search and replace. By matching code based on its underlying syntax tree rather than literal strings, it allows developers to perform complex tasks like finding specific function signatures, detecting structural anti-patterns, and executing project-wide refactors while safely preserving variable names. It is an essential tool for large-scale codebase migrations, API updates, and enforcing custom linting rules across diverse languages including JavaScript, TypeScript, Python, Rust, and Go.
