If anyone is “vibe coding without even knowing it”, which is highly dubious to begin with, that person will be terribly inexperienced anyway. They will not make mistakes which are “very hard to notice during a code review”. They will in fact be trivial to detect, if not by the code then by the description of the changes.
There’s no point to you spending the time adding the “guardrails” that will only in fact make your review harder. If 100% vibe-code is “nightmare fuel” to you, then making it harder to detect makes zero sense.
