This skill solves the difficulty of performing precise, shape-aware code searches and refactors that standard text-based grep tools cannot handle, such as matching specific function call patterns or complex structural declarations.
Use the ast-grep skill to find all instances of the connect method called on any receiver in the current rust codebase.

Structural code search parses source code into abstract syntax tree (AST) nodes to identify specific syntax patterns, ignoring formatting variations and comments. This allows precise matching of function call shapes or complex declarations.
Automated refactoring uses pattern-based replacement templates to safely rewrite code patterns globally. You can modernize deprecated APIs by replacing old method signatures with new ones across an entire repository.
AST-based code search supports multiple programming languages including Rust, Python, and TypeScript. The integrated engine parses source code from these languages into AST nodes for accurate structural matching.
Structural code search is shape-aware, overcoming standard text-based grep limitations. It matches specific function call patterns or complex structural declarations accurately, ignoring formatting variations and comments.
To find all instances of a method call, use structural search to match the receiver and method name pattern. This targets the specific function call syntax across the codebase, regardless of variable names.
AST refactoring requires an integrated ast-grep binary to parse source code into AST nodes. This binary is necessary for the engine to accurately identify and modify specific syntax patterns.
