Since gdevelop can use Javascript I recommend using Fallow (handles typescript and javascript, css and tailwind):
However you are asking AI to help you code you basically tell it that the code/step/phase cannot pass unless it meets the following Fallow output:
Average maintainability: 92–95+ acceptable range
Unused files: 0
Unused exports: 0
Unresolved imports: 0
Circular dependencies: 0
Boundary violations: 0
unused dev dependencies added: 0
This forces it to create 0 slop since the above things listed at 0 are AI’s weakness. And the maintainability score will only be achievable if it doesn’t create giant functions the other big weakness of AI.
If you do this at the start of your project you will never have slop. If you try and implement it after you start project. Backup the entire project and you will probably need a paid AI to refactor the code till get it to pass. And it might take a handful to a dozen passed depending on how large your code is etc.
