Open-Source Game Development Skills Pack Expands to 76 Playbooks

An open-source collection of game-development guidance for AI coding agents spans engines from Godot and Unity to Unreal and Phaser. It was described as a 74-skill pack; the project’s current catalog lists 76 skills, alongside a router that selects guidance for an engine and task. The collection is aimed at tools including Claude Code and Codex, and covers production tasks such as art direction, animation, performance work and publishing to Steam. The project repository describes the files as portable SKILL.md playbooks that compatible agents can load without converting them into a tool-specific format.
