I was doing this in a regular Claude Code session for a while, but wanted an all-in-one UI for it. Claude Code controls NetHack via tmux.

I have a NetHack skill installed that I update after each session.

My Claude's top score is 3302 (dungeon level 11).

It is interesting cause it mostly has trouble with spatial reasoning, even though it knows most/all the details of the game.

This absolutely CHEWS up tokens...lol.
