My notebook AI Robocoop is able to 1-shot whole notebooks now. By importing other notebooks you can add them to the context and then it has good examples of how to achieve something. I used to use it one cell at a time but now it seems to be able to do a crazy amount now without making a mistake (GPT 5.2). I think literate notebooks are a better medium for AI because of the prose and that it can see runtime values as well as the code.
