Why it's useful
A director skill hands work to specialists for gameplay, graphics, UI, debugging and release checks. Games come with a Vite starter, a seeded random generator and Playwright tests, including bot playtests, so the agent can check its own work instead of telling you it's done.
What it needs
Claude Code or Codex, and Node.js. The optional 3D, image and audio skills need Tripo, Gemini or ElevenLabs keys; the rest works without them.
