Box step is a beginner-level dance movement targeting the full body, written in Posecode, a small open-source language that LLMs like ChatGPT, Claude, and Gemini can write to describe human movement as text. Every joint angle below is hard-clamped to a safe range of motion.

1. Step forward-right0.9s · ease-in-out Step the right foot forward and out to the corner
2. Close the feet0.7s · ease-in-out Bring the left foot to meet it, standing tall on the corner
3. Step back-left0.9s · ease-in-out Step the left foot back to the start on the diagonal
4. Close home0.7s · ease-in-out Close the feet together, back home and ready to repeat
