I am curious with the use cases for something like this might be. I feel like it's very rare nowadays to encounter a CLI/TUI program that doesn't have a "non-interactive" alternative, either in a different tool or built into the application itself.

I know that pexpect can be used for testing such applications though. Is this meant to be for a similar use case? Or were "interactive-only" tools more common at one time in the past?

I think automating nethack is sufficient reason for this tool.

There's no wrong way to play, but savescumming makes it a different kind of game!

Sadly the AIs (nethackchallenge.com) are not yet good enough to show us what closer to optimal play looks like.
