Yes, gpt 5.4 always tries to compile/check my c++ code after every prompt. Despite it being in my AGENTS.md to never run builds. Then I have to explicitly mention it, but it will do it again randomly after.

What this means is the training/RL was trained with this workflow ;) But as you can tell, this workflow has no uses outside programming. Its just a hack to make it seem like the model is smart, but in fact its just them performing loops to get it right.
