This is essentially the Claude code, unmodified. (I added a try-catch as recommended by Devin.)

check-types started failing as a strange side-effect, but it was easy to fix and the fixes also make sense.

I'd rather have a separate unofficial-types.ts (or similar) that we maintain, that only includes the unofficial types that we added, and that we specifically need.
