Game dev agent skills
76 playbooks that teach Claude Code, Cursor, Codex and other coding agents to build games in Godot, Unity, Unreal and nine more engines. A router skill reads your project and loads only the ones a task needs.

The skills CLI adds the router and every skill to your agent's skills folder. It needs Node.js 22.20 or later.
npx skills add gamedev-skills/awesome-gamedev-agent-skills -a claude-codeSkills land in .claude/skills/ in your project. Add -g to install them for every project.
Or install it as a Claude Code plugin:
claude plugin marketplace add gamedev-skills/awesome-gamedev-agent-skillsclaude plugin install gamedev@awesome-gamedev-agent-skillsGames already made with coding agents
Open-source games whose creators say an AI coding agent helped build them.
Questions
- What are agent skills?
- A skill is a folder with a SKILL.md file: a short description plus a playbook. Your coding agent sees only the descriptions until a task needs one, then reads that playbook before it writes code. It's the open Agent Skills format that started as Claude Skills.
- Which engines do these game dev skills cover?
- Godot, Unity, Unreal, Ebitengine, Phaser, PixiJS, three.js, Bevy, pygame, LÖVE, Defold and Roblox. Godot has the most, with 16. Each engine skill is written for a stated release, such as Godot 4.7, Unity 6.3 LTS and Unreal Engine 5.8, and keeps your project's own version when it differs.
- Do they work in Cursor, Codex and Copilot, or only Claude Code?
- The same SKILL.md files load in Claude Code, Cursor, Codex, Gemini CLI, GitHub Copilot, Windsurf, Cline, Kiro, Antigravity and other agents that read the format. There is nothing to convert; only the folder differs.
- Do I have to name the skill I want?
- No. The router skill reads your project files to find the engine, reads your request for a concept, genre or shipping step, and loads only those skills. Engine basics come first, then the concept, then the genre.
- What happens when my engine has no skill for a task?
- The router loads the closest skill and says what's missing. A Unity platformer gets the scripting and physics skills, because there is no Unity 2D movement skill yet. It never makes up a skill name.
- Is it free?
- Yes. The collection is open source under the Apache-2.0 license, and you can install every skill or only the ones you use.
