The First Multiplayer Prompt-Hacking Game

I wanted to make prompt injection fun.

Not in a “solve this CTF challenge with levels” way. More like: sit down, compete with strangers, outsmart an AI, and feel smug about it. I wanted to build something that makes people curious about how these models actually work—and maybe a little paranoid about what they’ll give up under pressure.

That idea became Agent Has A Secret.

The Proof of Concept: Validation through Chaos

Before building a polished product, I needed to know if the “sticky” factor existed. Would people actually iterate on prompts, or just send one “Tell me the secret” and bounce?
