## Overview

This repository is a knowledge library of 27 Unreal Engine C++ skills for AI coding agents, not a runtime software service. The main workflow is a developer asks an agent for UE help; the agent reads project context, applies relevant skill guidance, and helps produce code. The README documents that context-first relationship and skill cross-references; source excerpts were not provided, so other wiring is omitted.

Main entry points: [`skills/ue-project-context/SKILL.md`](https://github.com/quodsoler/unreal-engine-skills/blob/main/skills/ue-project-context/SKILL.md) (Project Context), [`skills/ue-cpp-foundations/SKILL.md`](https://github.com/quodsoler/unreal-engine-skills/blob/main/skills/ue-cpp-foundations/SKILL.md) (C++ Foundations), [`skills/ue-actor-component-architecture/SKILL.md`](https://github.com/quodsoler/unreal-engine-skills/blob/main/skills/ue-actor-component-architecture/SKILL.md) (Actor Components), [`skills/ue-module-build-system/SKILL.md`](https://github.com/quodsoler/unreal-engine-skills/blob/main/skills/ue-module-build-system/SKILL.md) (Module Build)
