Unreal Engine Skills for AI Agents

A collection of 31 AI agent skills for Unreal Engine C++ development. Built for game developers who want AI coding agents to help write correct, production-quality UE5 C++ code. Works with Claude Code, Cursor, Windsurf, and any agent that supports the Agent Skills spec.

Target engine: Unreal Engine 5.8. Every API in every skill was checked against the UE 5.8 headers and source, and every C++ example compiles against 5.8. Where an API changed, each skill carries a "Deprecated — do not use" table mapping the old form to the 5.8 form, so an agent stops emitting the old one.

What are Skills?

Skills are markdown files that give AI agents specialized knowledge and workflows for specific tasks. When you add these to your project, your agent can recognize when you're working on an Unreal Engine task and apply the right patterns, APIs, and best practices.

How Skills Work Together

Skills reference each other and build on shared context. The ue-project-context skill is the foundation — it captures your project's modules, target platforms, and conventions so other skills can give relevant advice.
