What problem does it solve?

This Skill overcomes the limitations of traditional regex for code search and refactoring. It understands code structure, allowing you to find and transform patterns across multiple lines and languages, ignoring formatting differences, which saves immense time on large-scale refactorings.

Core Features & Use Cases

  • Structural Pattern Matching: Finds code patterns based on Abstract Syntax Tree (AST) structure, not just text, for precise results.
  • Smart Refactoring: Replaces code patterns while preserving formatting and semantic integrity across your codebase.
  • Use Case: Automatically migrate an old API call like user.getName() to user.profile.name across an entire codebase, ensuring all instances are updated correctly and consistently without manual review.

Quick Start

Example: Find all console.log statements in JavaScript files
