Stop feeding your AI agent entire engine manuals

What it does

This repository is a curated pack of 67 SKILL.md files—modular capability briefs for AI coding agents—covering ten game engines from Godot to Roblox. A router skill fingerprints your project files (a project.godot means Godot, a *.uproject means Unreal) and parses your natural-language request to load only the relevant briefs before the agent writes code. The result is targeted context instead of dumping an entire engine manual into the prompt window.

The interesting bit

The router composes skills additively: it picks one engine baseline, then layers on discipline and genre skills only if your task mentions them. There is also an art-direction workflow that locks a visual target and normalizes generated assets deterministically, rather than treating each sprite as a one-off prompt.

Key highlights

• 67 skills across 10 engines and cross-engine disciplines, each version-pinned to a stated engine release and validated by a script.
• The router detects your engine from project files and your task from plain language, loading exactly the matching skills and nothing else.
• Same SKILL.md format loads natively in Claude Code, Cursor, Kiro, Codex, Copilot, Gemini CLI, and dozens more without conversion.
• Includes a deterministic asset-production pipeline that checks generated art inside the game for cohesion.
• Every skill is written from primary documentation, not crowd-sourced guesswork.

Verdict

Worth a look if you use AI agents for game development and are tired of generic, context-heavy responses. Skip it if you prefer to hand-craft every prompt or aren’t using a supported agent.
