+## CRITICAL: File Editing on Windows
+
+### ⚠️ MANDATORY: Always Use Backslashes on Windows for File Paths
+
+When using Edit or MultiEdit tools on Windows, you MUST use backslashes (\) in file paths, NOT forward slashes (/).
+
+#### ❌ WRONG - Will cause errors:
+
+Edit(file_path: "D:/repos/project/file.tsx", ...)
+
+#### ✅ CORRECT - Always works:
+
+Edit(file_path: "D:\repos\project\file.tsx", ...)
