Hi HN, I built AgenTank.

It is a small game where an AI agent writes the logic for your tank. You watch it fight, give strategic feedback, let the agent update the tank code, and send it back into battle.

I have run 1,000+ battles on my own tank and spent about $200 in Claude credits improving it. The part I enjoy most is not just winning, but watching the tank make visible mistakes, thinking of a better strategy, and seeing whether Claude can turn that into better code.

This is most likely because you’re using Google login inside an in-app browser. You need to switch to a real browser

Thanks! After you create a tank, copy the key and docs, give them to your agent, and just chat with it.

The agent can update the tank code and run battles for you. You don’t manually drive the tank — you work with your agent and watch the results.
