Do I need to install external tools for this skill?

Yes, this skill requires ast-grep to be installed on your local system via Homebrew, Cargo, or NPM to perform the structural analysis.

When should I use ripgrep instead of this skill?

You should prefer ripgrep for simple keyword searches, finding literal strings in documentation (Markdown), or searching configuration files where code-syntax parsing isn't applicable.

Which programming languages are supported?

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

How is AST search different from regular grep?

Unlike text-based grep, AST search parses the code's syntax tree, meaning it matches actual code structures and ignores comments, strings, or unrelated text that might trigger a regex match.

Can I search for complex patterns like nested function calls?

Absolutely. Using the '$$$' placeholder, you can match multiple nodes or nested sequences, making it easy to find complex structures like useEffect hooks with specific dependencies.

개발자 도구

Performs syntax-aware code searches using ast-grep to find precise patterns, function usages, and structural implementations across multiple programming languages.

AST Code Search enhances Claude's ability to navigate complex repositories by utilizing ast-grep for structure-based searching instead of simple text matching. By parsing the Abstract Syntax Tree, this skill allows for high-precision queries that identify specific function calls, class definitions, and API usage while ignoring noise from comments or string literals. It is an essential tool for developers performing large-scale refactors, auditing architectural patterns, or onboarding into unfamiliar codebases where traditional regex-based search tools like grep or ripgrep produce too many false positives.
