Well yeah, and it wasn't, most of the pain was around rate limiting, lockouts and preventing exploits and making it work with this specific codebase.
I agree that with a clean codebase it will be simpler, maybe couple of days, just running code review workflow takes 15-30 minutes and then decisions llm makes for each problem is often not good and lead it into overengineering rabbit hole, which means I have to think about each problem and prevent it from escalating.
But yeah if "look, it sends the code and I can enter it to login" is enough validation then it can be made in 5 minutes, sure.
