ast-grep — синтаксический поиск и рефакторинг кода

engineering

ast-grep-find is a Claude Code skill that performs structural code search and refactoring via the ast-grep MCP server, matching syntax tree patterns rather than raw text. It locates function calls, class definitions, imports, and other constructs while skipping occurrences inside string literals and comments. Search scope can be narrowed with a directory path or a glob pattern, and multiple languages are supported — Python, JavaScript, TypeScript, Go, and more. The `--replace` flag with metavariables like `$NAME`, `$ ast-grep — синтаксический поиск и рефакторинг кода — Claude Code skill for software engineering , and `$_` enables precise codebase-wide refactoring, while `--dry-run` previews all changes before they are applied. It is the right choice when syntax-aware matching matters and a plain grep would produce false positives.
