Use Gamesteel from your agent.

Add the Gamesteel program to your agent with one command, sign in once, then ask your agent for a game. It does the agent’s work on your machine, and keeps your games on this website.

Thirty-one agents, each its own way

Your AI

The program runs through Node.js. The first time your agent asks it for something, the program opens Gamesteel’s sign-in in your browser: log in and Allow. It models in 3D with Blender when Blender is installed, and builds Android apps with Java and the Android SDK when they are.

npx gamesteel@latest connect lists all 30 agents and which of them are installed, npx gamesteel@latest connect claude sets one up, and npx gamesteel@latest connect claude --print shows what it would write, for adding it by hand.

The big AIs' own agents

Claude: npx gamesteel@latest connect claude Adds the Gamesteel program to Claude Code’s settings, ~/.claude.json: a server named gamesteel that runs npx -y gamesteel@latest.

The first time your agent asks it for something, the program opens Gamesteel’s sign-in in your browser: log in and Allow. It also lets Gamesteel’s tools run without asking, and gives Gamesteel two minutes to start, in Claude Code’s own settings, ~/.claude/settings.json.

Each agent you connect works in the workspace you pick when it signs in, as you, under the workspace’s plan. Disconnect it any time on the editor’s Agents page.

The chat apps in a browser, such as claude.ai and chatgpt.com, cannot start a program, so Gamesteel does not run in them: use an agent that runs on your machine.
