agent empire

live

An 8-bit real time strategy game about agent architecture

Command the orchestrator base. Incidents spawn and escalate in real time: ticket storms, latency spikes, risky refunds. Spend your token budget dispatching the right pattern-agent — 11 real patterns from RAG and ReAct to sagas, HITL gates, and sub-agents — and when you pick wrong the game stops the clock and tells you exactly why that pattern fails. Every scenario is drawn from real life experience building agent systems.

Ask the US Census anything, get auditable SQL back
