AST-Grep Find

Structural code search that understands syntax. Find patterns like function calls, imports, class definitions - not just text.

When to Use

• Find code patterns (ignores strings/comments)
• Search for function calls, class definitions, imports
• Refactor code with AST precision
• Rename variables/functions across codebase
