Spot checking, I don't see any issues.

e.g. https://github.com/ad-si/Woxi/blob/main/tests/list_tests.rs

  #[test]
  fn first() {
    assert_eq!(interpret("First[{1, 2, 3}]").unwrap(), "1");
    assert_eq!(interpret("First[{a, b, c}]").unwrap(), "a");
    assert_eq!(interpret("First[{True, False, False}]").unwrap(), "True");
  }

A very young project written by AI means you haven't reviewed the code and nobody has used it in anger. It might work perfectly, but my experience of AI so far says that it won't.
