Security testing will be the most important.

I've done a couple of tiny projects that I didn't feel like coding. So far, I have not been terribly impressed. Well, it is impressive that it can make something functional at all, and in one case, what it made was fine enough to use as the temporary project it was intended (sharing christmas music with friends/family - reading files from a directory and writing a javascript player to play them in a shuffled order).

In the other case, replicating a simple text-based old DOS game with simple rules (think a space-based game around the complexity of checkers or so), it failed to think of so many things that while it did what I told it for the most part, it wasn't a playable game. It was close, and fun enough for a nostalgic moment, but I had to work with it on logic like "If two fleets of ships arrive at the same planet in the same turn, you have to see how the first battle goes. If the first battle captures the planet, the second fleet is not attacking the first fleet's ships - we won the planet at that point". Very simple concepts that sure, you'd have to think of as a programmer, but if you were telling another person about how the game should work, were things I felt another person would think about.

I hope AI works well for you. Anywhere security it needed like database sanitation or user credentials....... I hope you test thoroughly and I hope you can tell it enough to remind it to implement things like sanitation and other safety measures. An app can certainly appear to be working, but give many many fronts for attack. That's my main worry with AI code. I worry enough on the little projects I do if I'm being secure enough myself.
