Even the most advanced LLMs still make mistakes.

I firmly believe that before solving other people's pain points, you must first solve your own!

I've recently been turning my Excel ledger into an app. Once I finished the entire app architecture, I handed my Excel ledger over to Claude Code to input the data into the app and verify for errors. The good news is that it successfully filled in most of the answers correctly; the bad news is that in some ambiguous areas, even though I thought the data I provided was quite comprehensive, it still made mistakes! Fortunately, it wasn't anything major; everything is still fixable, and I can truly understand where it tends to go wrong.

I still rely on it and trust it.
