Have been using gpt4 and just copying all the relevant files in with something along the lines of
```
Given these X files, help me assess how best to implement feature Y. Ask any clarifying questions that may assist with writing a best practice solution.
*File 1*
*File 2*
*File 3*
...
```
If the context length is a problem I'll use claude-100k.
Pretty much always results in good quality code.
I'll then typically open a new window context and get it to review according to best practices highlighting missing e.g. error handling or possible edge cases.
