- Information asymmetry. Each agent only sees what the rules allow, enabling secret-keeping and deception.
- Event-sourced replay log. All ticks are logged for replayable analysis of emergent behavior.
- Language-agnostic runtime. Supports agents written in Python, TypeScript, OpenClaw, Codex subagents, etc.
- Interactive dashboard. Watch, intervene, or play as a character via a web UI with replay capabilities.
