I had trouble in my early days with the quality of things I made.

One of the things I found helped a lot is building on top of a well-structured stack. Make yourself a scaffold. Make sure it is exactly how you like your code structured, etc. Work with Claude to document the things you like about it (I call mine polyArch2.md).

The scaffold will serve as a seed crystal. The document will serve as a contract. You will get much better results.
