Make a Maimbrain game with your agent

Games are small Rust → WebAssembly programs. You describe the game; your agent (Claude Code) builds it with the Maimbrain skill and uploads it as a private draft. You play the draft on your iPhone, and when it's right you submit it for review.

1. Install the mb tool

   macOS or Linux:

   curl -fsSL https://maimbrain.com/install.sh | sh

   Windows (PowerShell):

   irm https://maimbrain.com/install.ps1 | iex

   It also needs Rust (rustup) with the wasm32-unknown-unknown target; mb doctor checks everything and says how to install what's missing on your system.

2. Add the Maimbrain plugin to Claude Code

   /plugin marketplace add maimbrain-com/maimbrain-kit
   /plugin install maimbrain@maimbrain-kit

   It carries the maimbrain-game skill: the spec, a design guide for what works in the feed, a starter template, and tools for pixel art and 8-bit sound.

3. Sign in from your terminal

   mb login

   It shows a code; approve it at https://maimbrain.com/device (sign in first).

4. Ask your agent for a game

   Use the maimbrain-game skill to make a game: a frog that has to catch flies by tilting the phone,
   with a hungry boss fly every 30 seconds. Start with `mb new`, follow the skill's workflow
   and checklists, and when it's done run `mb publish`.

5. Play the draft on your iPhone

   mb publish uploads a draft that only you, and anyone you invite to test it, can play. In the Maimbrain app it's first in your feed, with a My Game Studio button on its card, and under Account → My Game Studio. Fix what you find and run mb publish again: the new upload replaces the draft. Tell players what it is with mb describe mygame "…" (or in My Game Studio); a description isn't part of the bundle, so you can change it any time.

6. Submit it for review

   mb submit mygame

   Or tap Submit in My Game Studio in the app, or use the button below. A moderator plays it; once approved it's in everyone's feed. If an older version is live, it stays live until then.
