Build a Superyacht Docking Game with Claude Code & Opus 5.5 | three.js, JavaScript | No Game Engine

🛥️ Claude Opus 5.5 built this superyacht docking game inside Claude Code: a 46 m yacht with twin engines, bow and stern thrusters, gusting crosswinds, and a Mediterranean harbour town generated entirely from code. Reverse into a gap barely wider than the boat. Every bump costs a star. It runs in your browser with three.js. No game engine, no 3D models, zero lines of code written by hand. 🚀 PROJECT & DEMO ✨ Play the game (live demo): https://vibe-harbor-master.pages.dev 💻 Source code (free, MIT): https://github.com/hirosichen/ai-harbor-ma... 🤖 Watch the AI dock the yacht itself: https://vibe-harbor-master.pages.dev/?auto... 🧩 The Claude Code skill used (free): https://github.com/hirosichen/ai-harbor-ma... ✈️ Also built this way: an island air-race game    • Build a 3D Flight Racing Game with Claude ...   and an F1 racing game    • Build an F1 Racing Game with Claude Code &...   🛠️ TOOLS USED • Claude Code + Claude Opus 5.5 (type /model to switch) • A Claude Code skill with the game workflow (research → build → test hooks → verify → fix → ship) • three.js r186 from a CDN (no npm install, no build step) 💬 THE PROMPT (translated) "Make me a new game.
