Game-development expertise for AI coding agents — install once, and a router loads the right skill for whatever you're building.

Agent Skills are small capability files an AI agent loads only when it needs them. This repo gives your agent 66 game-dev skills and a router that picks the right ones for you. You describe what you're building; the agent loads the matching engine and task skills before it writes code.

• Cross-engine. Godot, Unity, Unreal, Phaser, PixiJS, three.js, Bevy, pygame, LÖVE, Roblox.
• You don't pick skills. The router detects your engine and task and loads only what fits.
• Built to trust. Every skill is written from primary docs, version-pinned to a stated engine release, and checked by a validator.

• Quick start
• What you can ask
• How the router picks skills
• Catalog
• Agent compatibility

One command, any agent. The skills CLI detects the coding agent you already use and installs the router plus all 66 skills into the right place:

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

Add --list to preview first, -g to install for every project, or -a <agent> to target a specific tool (-a cursor, -a claude-code, -a gemini-cli, …). The same SKILL.md files load natively in Claude Code, Cursor, Windsurf, Cline, Codex, Gemini CLI, GitHub Copilot, Kiro, and dozens more — there's nothing to convert.

Claude Code plugin (alternative). This repo is also a Claude Code plugin marketplace, so you can install it with Claude's own commands:

claude plugin marketplace add gamedev-skills/awesome-gamedev-agent-skills
claude plugin install gamedev@awesome-gamedev-agent-skills

Building in only one engine? Install a smaller bundle — router plus your engine:

claude plugin install router@awesome-gamedev-agent-skills
claude plugin install godot@awesome-gamedev-agent-skills    # or: unity · unreal · web-engines · other-engines

Prefer to copy the files by hand, or want the exact per-tool paths? See docs/INSTALLATION.md.

Then just talk to your agent — see below.

Describe the task in plain language. The router figures out the skills:

You never type the skill names on the right. That's the router's job.

You never name a skill. On each request the router does three things:

1. Detects your engine from project files — a project.godot means Godot, a *.uproject means Unreal, and so on. If it can't tell, it just asks.
2. Reads your request for the task — a concept (AI, shaders, saving), a genre (platformer, roguelike), or a shipping step (game jam, Steam).
3. Loads only the matching skills, in order: engine basics first, then the concept, then any genre glue. It re-routes if you switch to something new.

That's why "add a double jump to my Godot player" loads godot-2d-movement + platformer and nothing else.

66 skills across 8 categories — each links to its SKILL.md below.

Cross-engine concepts that load alongside the detected engine skill.

Compositional templates that orchestrate engine + discipline skills; they never re-teach primitives.

Every skill here is a plain SKILL.md folder in the Agent Skills open standard — metadata plus a Markdown playbook the agent reads on demand.

The same file loads natively across the ecosystem: Claude Code, Claude, Cursor, Windsurf, Cline, OpenAI Codex, Gemini CLI, GitHub Copilot, Kiro, Antigravity, VS Code, and many more. There are no editor-specific rule files to maintain and nothing to convert.

Install with one command. The universal CLI detects your agent and writes the skills to the right place:

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

Or copy by hand. Drop a skill's <name>/ folder into your agent's skills directory:

The exact per-agent paths, triggers, and the handful of optional fields that vary by agent are in docs/COMPATIBILITY.md.

One plain-English request goes in; the minimal right skills come out, then version-pinned code. Here's the shape of a single exchange (illustrative):

> add a double jump to my player

Detected Godot (project.godot). Loading godot-2d-movement for the controller
and platformer for jump feel — skipping the other 64 skills.

@export var speed := 220.0
@export var jump_velocity := -380.0
