What it does
- Every terminal is a real agent. Claude Code, Antigravity (Gemini), OpenAI Codex, xAI Grok, Kimi Code, Gemini CLI, Qwen, OpenCode, Crush, pi.dev, GitHub Copilot CLI, Cursor, or a custom command, each in its own node-pty PTY, rendered with xt
- Every agent is an avatar. A Pixi.js office floor where agents walk to stations, envelopes fly desk to desk, and avatar state reflects real work.
- A GOD orchestrator you talk to. It routes tasks, adjudicates traffic, and escalates only what needs a human. Or press Talk and run the floor by voice.
- Per-agent git worktrees. Optional isolation so parallel agents never collide on branches.
- More than one floor (0.5.3). File, New Floor opens another office on its own folder, in its own window, with its own agents, board and memory. A folder only ever opens in one floor, and one licence covers them all.
