I suppose that would just be an interactive CLI. Usually I think of them as one-and-done invocations like sed. It's definitely not an ideal mode as evidenced by the current popularity of vim over ed, but it's better than a program being unusable.
claude code would fit this model as the most important point is the prompt. Just make the rest of the interactions be commands.
