Today I did a change that was across two apps, different projects, client and server. I tested it as best I could for now, and it appears to work in both apps. But now I have an extra level of confidence because I asked Claude to do a code review, checking all my assumptions and it does find egregious mistakes, that in the past might have taken a day in a debugger to track down. Now it can happen in less than the time that it took for me to write this post. Now I’m going to check to see how it did.
