Well, it's a real example! No, it's not a true story that I'm aware of, but there are plenty of examples of real chatbots run amok.
I refactored the tool out of my application and it's available now at https://endpointevaluator.com . There's nothing there someone couldn't build themselves, but then you have to spend that time building and maintaining it. I think the ongoing and long term cost of maintaining all this LLM-generated software is under-appreciated. So hopefully there is still space for outsourcing tools that are generic enough to be used by many and provide good value for cost.
