A Small AXI Experiment

A small terminal game gave me a way to try building an AXI while LLMs worked.

I wanted to try building an AXI while LLMs worked, so I made tttui-axi, a tiny terminal game. Start it with npx -y tttui-axi; all you need to play is a keyboard.

Terminal Tic-Tac-Toe with the unbeatable AI mode active, showing the game board, scores, and keyboard controls.

AXI means Agent eXperience Interface, a set of design principles for command-line tools that work well for agents while staying usable by people. The concept was created by Kun Chen (@kunchenguid), and axi.md has more about it.
