Learn AI Agents
By Playing Games
Build a prompt layer by layer, run it through a live AI game, and see exactly what each change is worth.
Prompt Anatomy
Seven lessons. Each one adds a new layer to your prompt and runs it against a live AI game.

Build, Run, Measure
Every challenge follows the same loop. You write, the AI plays, and the scoreboard shows what changed.
Build your prompt
Each challenge unlocks a new section — identity, principles, strategies, examples. Your prompt grows layer by layer.
Run it live
Your prompt drives an AI agent through Word Guess in real time. Every move traces back to what you wrote.
Measure the difference
Compare models side by side. Inspect full replays. Know exactly which layer made the score jump.
Built to Teach by Doing
You write every line
Build a real AI agent from scratch. Your prompt drives every decision it makes in a live game.
Every edit has a score
Word accuracy, rounds solved, turns per solve — all updating in real time as your prompt improves.
One concept at a time
Each lesson builds on the last. You always have a working prompt to start from and a clear next step.
