Unreal Engine Skills (quodsoler)
31 Unreal Engine C++ skills checked against the UE 5.8 headers: gameplay framework, GAS, animation, networking, rendering, AI, UI, tools and more.
Listed from the author's README. GameSkill has not run this end to end yet. Agent support and install steps are as documented by the author.
Install
npx skills add quodsoler/unreal-engine-skills --skill ue-project-context ue-cpp-foundationsInstalls this skill plus ue-project-context, which writes the project document every skill in this pack reads first. Add -a claude-code (puts it in .claude/skills/), -a codex or -a cursor (.agents/skills/) to choose the agent, and -g to install it for your user instead of the project.
Commands are copied from the project's README. Check the repository before running anything on your machine.
Install for a specific agent
| Agents | -a | Folder |
|---|---|---|
| Claude Code | claude-code | .claude/skills/ |
| Codex | codex | .agents/skills/ |
| Cursor | cursor | .agents/skills/ |
| Gemini CLI | gemini-cli | .agents/skills/ |
| GitHub Copilot | github-copilot | .agents/skills/ |
| OpenCode | opencode | .agents/skills/ |
| Windsurf | windsurf | .windsurf/skills/ |
Add -a <flag> to the command. These are project folders; add -g to install for your user account instead.
What you get
- A pitfalls section with the mistakes to avoid
- Bundled 3 reference docs the agent reads when needed
- Written for Unreal Engine 5.8
Good fit
- Writing Unreal Engine C++ that touches the reflection system or core types
Not for
- Actor and component lifecycle: use UE Actor & Component Architecture instead
- Blueprint-facing functions and latent actions: use UE Blueprint and C++ Interop instead

Good to know
Skills in Unreal Engine Skills read .agents/ue-project-context.md, which the ue-project-context skill writes from your project's modules and conventions. Every API is checked against the UE 5.8 headers.
Requirements
- Unreal Engine 5.8
- Unreal Engine 5.8 C++ project
