I decided to try to use it up over the weekend using (mostly) my phone and vibe coded a Prolog interpreter.
Now I'm seeing how far I can push it.
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.

An easy way to find out if your implementation works is to try out the `likes.pl`[1] example found in the SWI-Prolog "Getting started quickly"[0] documentation.

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.

Since you've submitted a "Show HN: Vibe Prolog" and shared in the repo:
I was working on something else and as a side effect
accidently vibe coded a prolog interpretor on my phone over
the weekend.
Especially since there have been 82 commits in the span of 3 days.
EDIT:
And I am really interested in how you "vibe coded" the commit[0] which made this singular change:
- uv run pytest tests/ttest_additional_builtins.py -v
+ uv run pytest tests/test_additional_builtins.py -v
