Add real-time or turn-based multiplayer to an existing browser game using PartyKit (Cloudflare Durable Objects). Scaffolds a room-based server, a NetworkManager client, EventBus events, GameState fields, Constants, and extends render_game_to_text(). Use when the user says "add multiplayer", "make this multiplayer", "add real-time co-op", "add online play", "scaffold multiplayer", or "add netcode". Do NOT use for solo leaderboards (use monetize-game), single-player AI opponents (use add-feature), or peer-to-peer/WebRTC games.
This skill does not declare a tool allowlist. The agent host applies whatever default tools are available at runtime.
