Every game on this page came from the same three-paragraph prompt. You don’t steer it — you set a bar and let the agent run the gauntlet.
Read the method
The Gauntlet Loop in eight minutes: give the agent a real bar, split the work, and never let the builder grade itself. Read it here.
Copy the prompt
The exact prompt behind Claude of Duty is open source — three short paragraphs. Swap in whatever game you want.
Let it loop
Run it in Claude Code with Opus 5, turn on ultracode, and walk away. Stop the run when you love what you see.
