The skills use the portable SKILL.md format and are organized around game-engine and production tasks.
The catalog lists support for Godot, Unity, Unreal Engine, Phaser, PixiJS, three.js, Bevy, pygame, LÖVE, and Roblox. Its repository also includes a router intended to direct a request to relevant skills, alongside installation material for agents including Claude Code and Codex.
The project describes skills covering areas such as graphics, character animation, performance work, and Steam publishing. It is an open-source catalog rather than a single game-building agent or a hosted service.
The repository does not establish the quality of every skill, benchmark their outcomes, or prove compatibility with every listed engine and agent configuration. Those claims require testing in a particular project environment.
