The official installer, Claude Code plugin manifest, and release host for ongame — an AI game-making assistant that runs as a CLI + Claude Code plugin.
This repository is deliberately small. It contains no application source — only the pieces needed
to install and keep the real ongame-cli binary up to date:
install.sh— the one-line installer..claude-plugin/— the Claude Code plugin manifest + marketplace listing (a static shim that points at the installed binary; it is not the application itself).bin/ongame-launcher— a small, dependency-free launcher that self-updates the binary and hands off to it.codex/config-snippet.toml— the MCP server registration block for OpenAI Codex CLI users.
The actual ongame-cli binary (and everything it talks to) is closed source. See
LICENSE.
curl -fsSL https://cli.ongame.ai/install.sh | sh
This detects your OS/arch, downloads and checksum-verifies the matching ongame-cli binary from
this repo's Releases, installs it to
~/.ongame/bin, adds it to your PATH, and — if it finds claude or a Codex CLI install on your
machine — wires up the MCP integration for you.
install.sh registers the marketplace and installs the plugin automatically when claude is on
your PATH — nothing to paste. If a Claude Code session is already open, run /reload-plugins
there; otherwise just start one and type /make-game <your game idea>. (Manual fallback, only if
the automatic step reported a failure: /plugin marketplace add gamebyte-ai/ongame-cli then
/plugin install ongame@ongame-cli.)
If ~/.codex/ exists, install.sh already patched ~/.codex/config.toml for you. To do it by
hand instead, copy codex/config-snippet.toml into your own config.
You never need to re-run the installer or update the plugin by hand. ongame-cli checks for a
newer release on every launch and swaps itself in place (checksum-verified) before running — the
Claude Code plugin manifest itself almost never changes. A new version takes effect on your next
Claude Code / Codex session, the same way any other config change would.
