The correct thing to do is to annotate the code and the PR with comments. You shouldn't be submitting code you don't understand in the first place. These comments will contain the reasoning in the prompts. Giving me a list of prompts would just be annoying and messy, not informative.

Also, we should not be submitting huge PRs in general. It is difficult to be thorough in such cases. Changes will be less well understood and more bugs will sneak their way into the code base.
