Perfect example. You mean the C compiler that literally failed to compile a hello world [0] (which was given in it's readme)?

Hallucinating APIs for well documented libraries/interfaces, ignoring explicit instructions for how to do things, and making very simple logic errors in 30-100 line scripts.

As an example, I asked Claude code to help me with a Roblox game last weekend, and specifically asked it to "create a shop GUI for <X> which scales with the UI, and opens when you press E next to the character". It proceeded to create a GUI with absolute sizings, get stuck on an API hallucination for handling input, and also, when I got it unstuck, it didn't actually work.
