More times than I'd care to admit, I've skimmed terraform plan/apply and missed important details. Either due to fatigue from so many lines, naively thinking that I was only making a small change, or just general carelessness, something like this would have saved me a few times now.I made sure to still output the full diffs, but just include a summary at the end, right before the confirmation for apply.
Basic implementation is just OpenAI models, but I've built it with expanding to other model providers in mind.
