I "wrote" this DNS validator to help me migrate DNS from one service to another and make sure I didn't miss anything. I didn't write any code (or even the README or example BIND file) and just used AI (Anthropic's Claude 3.7 Sonnet) to write the initial version and iterate until I got all the features I think are needed. I have not reviewed the code (so there may be bugs) but it seems to work properly. For me this is a super eye-opener with what is going to happen next in the tech industry.
