It's not playing in-context of minecraft, it's playing in-context of an API to minecraft. You can see one of the limitations in its error condition when it tries to craft an "acacia axe" out of acacia planks and sticks, fails, and then replaces all the references to "wooden axe". Of course in the real world it doesn't matter what you call the axe you made, and it's pretty clear what an acacia axe is. Even if it did matter, you could also easily keep the function name and output message, and just make an "wooden axe" behind the scenes. The fact that the GPT is so tightly bound to the formalism of the API is an indication that this is a task the GPT can likely do quite well as this API is well-used and documented.
