Installation

Prerequisites:

Python 3.12 or newer.
uv.
tmux.
At least one supported agent CLI: Claude Code or Codex.

Node.js and npm are not required for the standard VibeGame setup.

First-time Claude Code users: VibeGame launches agents with claude --dangerously-skip-permissions. If you have never used this flag before, run it once in a terminal and accept the confirmation prompt — the first-run consent screen cannot be completed inside VibeGame's managed session, and agent startup will fail without it.

git clone https://github.com/tettethu/VibeGame
cd VibeGame

Tell your agent (Claude Code or Codex):

Read and follow the instructions in @docs/SETUP.md to set up this project for me.

Or set it up manually:

./setup.sh

setup.sh links the installed vibegame command to this checkout so the CLI
can use the bundled engine, templates, and Dashboard. Keep the checkout
available; pulling updates changes the installed CLI without reinstalling it.

Quick Start

mkdir my-game && cd my-game
vibegame init
vibegame start

Or start an existing project from another directory:

vibegame start --project ./my-game "Continue polishing the boss fight"

Use VibeGame's standard build workflow for an end-to-end game development goal:

/vibegame-build Build a compact roguelike dungeon with one boss encounter

Run or close the game directly:

vibegame run --port auto
vibegame close

VibeGame Dashboard

We provide a web dashboard for interacting more freely with the agent team and manually editing game properties.

Roadmap

Acknowledgments

We are inspired by the broader community exploring AI agents for game creation, game development, and gameplay. We thank the teams behind GameDevBench, OpenGame, GameCraft-Bench, and other open-source projects for advancing this field and sharing their work with the community.
