What are the odds :) I made this two weeks ago, also with Claude.
This one's a straight port, paip-python's[0] Prolog interpreter. (Itself based on Norvig's Paradigms of Artificial Intelligence Programming book, originally in Lisp.)[1]

It was in the web ui, so I expected it to give me a code block, but it spun up a vm, set up a npm project, generated tests... ran them. I was quite surprised.
Your version is the opposite of mine, in a very good way. Your one is mostly tests! My version's tests are... well, you'll see ;)
Both are surprisingly short. 700-ish for mine, ~1200-ish for yours (as far as the actual interpreter goes), right?
That seems like a lot of bang per buck for something as powerful as a Prolog interpreter! I don't know very much about Prolog though, so maybe there's a lot of crucial parts missing here.
At any rate the original is a teaching device, and the book[1] goes into some length on the limitations of Prolog, both this version and in general.

If the project is about testing Claude's capabilities, the prompts will be more interesting to have.
Have you considered asking for a version in assembly?
Here's an idea.
There have been over a dozen commits in the last 2 hours. If you are actually "vibe coding" a Prolog, then post the prompts you have used in the last 2 hours here.
If it helps to have a specific starting point, commit 7bbe652[0] is as good as any.
