Claude Code Game Studios

Turns Claude Code into a full game studio: 49 agents and 72 workflow skills arranged like a real studio hierarchy.

Listed from the author's README. GameSkill has not run this end to end yet. Agent support and install steps are as documented by the author.

Install

Inside Claude Code Game Studios (recommended)
git clone https://github.com/Donchitos/Claude-Code-Game-Studios.git my-game
cd my-game
claude

The skill ships with the template. Run it as /prototype inside Claude Code; it reads project.yaml and works with the studio's agents.

Skill folder only
npx skills add Donchitos/Claude-Code-Game-Studios --skill prototype -a claude-code

Copies just this skill. It expects the studio template around it, so some steps may not work on their own.

Commands are copied from the project's README. Check the repository before running anything on your machine.

What you get

  • A verification step before the work is called done
  • Bundled 10 reference docs the agent reads when needed

Good fit

  • Testing a concept with a throwaway HTML, engine or paper prototype before writing GDDs
  • Getting a proceed, pivot or kill decision on an idea

Not for

  • Projects that don't use the Claude Code Game Studios template: the skill relies on its project.yaml and agents

Try this prompt

Prompt
Prototype our core loop and tell me whether to proceed, pivot or kill it.
