-## Type Safety Improvements
-
-### Add Return Type Annotations to Transformer Methods
-- **Priority**: High
-- **Description**: Add proper TypeScript return type annotations to all transformer methods in v15-to-v16.ts (and other transformers)
-- **Benefit**: Would catch structural issues like double-wrapping at compile time instead of runtime
-- **Example**: 
-  ```typescript
-  TypeName(node: PG15.TypeName, context: TransformerContext): { TypeName: PG16.TypeName } {
-    // implementation
-  }
-  ```
-- **Impact**: Prevents bugs like the double-wrapping issue we encountered where `{"TypeName": {"TypeName": {...}}}` was produced instead of `{"TypeName": {...}}`
-
-### Improve Type Definitions
-- Add stricter typing for node transformation methods
-- Consider using mapped types for consistent return type patterns
-- Add compile-time validation for node wrapping consistency
-
-## Testing Improvements
-- Add unit tests for individual transformer methods
-- Create focused test cases for edge cases like empty Integer nodes
-- Improve error messages in transformation mismatches
-
-## Documentation
-- Document transformation patterns and conventions
-- Add examples of proper node wrapping
-- Document debugging strategies for transformation issues
+- [ ] add skip file that annotates which files for full transform to skip, including reason and versions
