Students do something akin to vibe coding I guess. It may seem impressive at first glance but if anything breaks you are so, so lost. Maybe that’s it, break the student’s code, see how they fix it. The vibe coding student is easily separate from the real one (of course this real coder can also use AI, just not yoloing it).

I guess you can apply similar mechanics to reports. Some deeper questions and you will know if the report was self written or if an AI did it.
