What is it?

Three.js Game Skills is a set of agent skills for Codex and Claude Code aimed at building browser games with Three.js. The entry point is threejs-game-director, which routes requests to specialist skills covering gameplay systems, graphics, UI, debugging, QA and release, plus 3D, image and audio asset generation. Each skill folder bundles its own SKILL.md, references, helper scripts and assets.

The package includes a Vite + TypeScript + Three.js scaffold. Generated games come with deterministic test hooks, a seeded RNG, and Playwright templates for smoke tests, visual-regression baselines and bot playtests, so an agent can check its own work in a browser. A canvas inspection helper reports pixel metrics and render-budget data, and an evidence checker validates a declared set of screenshots against a run ID.

External asset generation is optional. Tripo handles 3D models, Gemini handles images and ElevenLabs handles audio, each through its own API key. When keys are missing, the director falls back to procedural assets and reports the limitation.

Things to know

Works with Codex and Claude Code agents only, not as a standalone game engine.
Some asset generation features need paid API keys for Tripo, Gemini, or ElevenLabs; otherwise the agent falls back to procedural assets.
