I completely agree. My first intervention with this person was to try to get them to set up a test driven development framework. Unfortunately, that's also when I learned he didn't know what that was. He also just copied "do TTD" into Claude. It was definitely my mistake, and probably over optimism about what AI might be able to do, that we didn't enforce that a lot earlier, and have been working on making sure to enforce a lot more gates going forward.
