Prompt for your agent

Goal: Ship my three.js experiment as a real iOS game.
Setup: agents used in source: Codex; tools/MCPs stated: iOS.
Steps:
1. Start from the three.js web experience built around your 3D scan.
2. Have Codex port it to a native iOS app.
3. Add features: leaderboards and competing with friends for the cleanest cut.
Rules: ask me before anything irreversible (sending, posting, paying, deleting); don’t invent data, results or tools I haven’t given you; tell me what you couldn’t verify.
