AI tooling must be disclosed for contributions

I support this idea. All the prompts and responses should be committed to git

What if you did not use a prompt, but, for example, the fancy auto-complete feature in Visual Studio that for example GitHub Copilot provides (i.e. accept huge code completion automatically suggested by Copilot via tab key)?

Well, that one is trouble especially if the code is not reviewed completely

I dont use it personally. I think there should be a tight code review or disallow large auto completes altogether.
