  • Line-based text editing with string or regex support - Preview edits with a dry run feature - Two-step approval process for safer editing - Tools for searching files and retrieving specific lines - Intelligent whitespace handling and pattern matching
  1. Making complex modifications to JavaScript or TypeScript files.
  2. Updating configurations while preserving file structure.
  3. Searching files for specific components or patterns before editing.
