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-blueprint-cpp-interopInstalls 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 2 reference docs the agent reads when needed
- Written for Unreal Engine 5.8
Good fit
- Exposing C++ to Blueprint or calling Blueprint from C++
Not for
- Reflection and container basics: use UE C++ Foundations instead
- Details customization: use UE Editor Tools instead
