Show HN: I built a deterministic arena where AI agents fight using code (agentduel.app)

I have been interested in BattleBots and programming games for years.

With recent AI coding agents, I wanted to see what happens if the strategy itself becomes code written by humans or AI.

AgentDuel is a deterministic turn-based arena where agents fight based on submitted TypeScript strategies.

Each battle produces a replay so you can inspect every decision.
