awesome-gamedev-agent-skills: Game-Dev Skills for 12 Engines

Overview

awesome-gamedev-agent-skills is a collection of Agent Skills, the open standard for on-demand agent instructions, plus a router that chooses relevant skills for a game-development task. It is built for AI coding agents working with 12 engines, including Godot, Unity, Unreal, Roblox, Bevy, Phaser, PixiJS and three.js. The aim is to avoid loading irrelevant guidance: the router identifies the engine and task, then selects a small set of skills before the agent writes code.

The skills cover engine-specific work as well as cross-engine disciplines, genres and workflows. This suits developers who want an AI coding agent to help with an existing game project or a new one without manually choosing from a large catalog. The repository says its guidance is based on official engine documentation and that examples were run or compiled on real toolchains for 10 of the 12 engines.

Key Features

• Router detects the project engine from files such as project.godot and *.uproject, then selects matching skills.
• Engine guidance for 12 engines, from Godot, Unity and Unreal to Ebitengine, Phaser, Bevy and Roblox.
• Cross-engine skills for areas such as saving, game AI, procedural generation, audio, input and performance.
• Genre and workflow guidance for projects such as platformers, roguelikes, game jams and publishing to Steam or itch.io.
• A game-asset workflow covering visual direction, asset families, normalization and in-game checks.
• Skills use the Agent Skills SKILL.md format and are available to compatible agents including Claude Code, Cursor, Codex, Gemini CLI and GitHub Copilot.
• Validation tooling and tests support skill authoring and maintenance.

Use Cases

• A Godot developer can ask an agent to add a player movement feature and have it combine engine-specific movement guidance with platformer design advice.
• A small team prototyping in an unfamiliar supported engine can give its coding agent focused, version-aware implementation guidance.
• A solo developer can use cross-engine skills for game systems such as saves, dialogue, procedural generation or input without writing those instructions from scratch.
• A game-jam participant can ask for help scoping work and checking a build against the jam workflow.
• A developer preparing a release can use the Steam or itch.io publishing skills for platform-specific shipping steps.

Getting Started

Install with the Skills CLI, which requires Node.js 22.20 or later:

npx skills add gamedev-skills/awesome-gamedev-agent-skills

See the README for targeted and Claude Code plugin installation options, compatibility details and the full skill catalog.

Considerations

The repository is less than six months old and is changing quickly. Recent activity includes frequent commits and releases, and reported issue and pull-request handling is brisk, but most contributions come from one person. That concentration is worth considering if your team depends on ongoing updates or wants to maintain the collection over time.

Guidance is pinned to stated engine versions, so confirm that the relevant skill matches your project's actual version and workflow. The repository reports that examples have been run or compiled on real toolchains for 10 engines, leaving two without that same stated level of validation. Installation through the universal CLI requires Node.js 22.20 or later; the README also documents manual and agent-specific alternatives. The project uses Apache-2.0, with attribution and trademark notes in its NOTICE file.
