Dev majidmanzarpour updated his open-source Three.js game development agent skills pack (2.2k GitHub stars) for Codex and Claude Code. Nine skills are routed by a 'director' skill covering gameplay, graphics, UI, asset generation, audio, debugging, and release verification. This update: tuned for Claude Opus 5.5, adds ElevenLabs AI music generation, cuts QA screenshot output 10x and mobile cost 5x, with skill routing tested over 80+ runs. Generated games ship with deterministic test hooks, seeded RNG, and Playwright templates for smoke tests, visual regression, and bot playtests.
