Six installable skills for Claude Code, Codex and any agent that reads SKILL.md files: game design, game feel, level design, game programming, XR and game audio.

Generic prompts get you generic games. This pack gives your agent the working rules game developers learn the slow way: how to tune a jump until it feels right, why players get lost in a level, which code patterns keep a project changeable, how to keep VR comfortable, and how to mix audio so it doesn’t tire the ear.

Each skill is a plain-text playbook distilled from the craft literature (design lenses and the Three Cs, game feel tuning, architectural level design, game programming patterns, VR human factors, game sound and mixing), rewritten as checklists your agent applies step by step and uses to review its own work.

Works with: Claude Code, Codex CLI, Cursor, Hermes/Pi, or paste into any chat model. Install: copy the folders into your agent’s skills directory (2 minutes; steps in the guide).
