What it does
unreal-engine-skills is a knowledge library about Unreal Engine for an agent that writes C++ and assembles a project itself. The skills give correct classes, real API signatures, patterns and gotchas with references into the engine source; there are no editor click-throughs or tool instructions. Each skill sits in a folder with a `SKILL.md` and optionally `references/`, `scripts/` and `assets/`, following the Agent Skills specification. The set has four categories: `core`, `metahuman`, `ultra-dynamic-sky` and `ultra-dynamic-weather`. The core covers UObject reflection, modules and `*.Build.cs`, memory and garbage collection, delegates, subsystems, Enhanced Input, the Gameplay Ability System, Blueprints and their link to C++, assets, materials, animation and Control Rig. Other skills plan game architecture, locate exact APIs in the engine source and apply Epic's coding standard. The target is Unreal Engine 5.8. `scripts/check-citations.mjs` verifies that every cited source path exists on disk, and `evals/tasks/` holds golden tasks for comparing agent output with and without a skill.
Who it is for. Unreal Engine 5 game developers who let Claude Code or Codex write gameplay C++ and set up Blueprints and materials.
Good fit when
- The agent writes a C++ class with UPROPERTY and UFUNCTION and needs correct macros, ownership and garbage collection behavior
- The project builds an ability system on GAS and cares about attributes, effects and tasks
- Enhanced Input has to be wired to a character with mapping contexts and actions
- A level needs time of day and weather on the Ultra Dynamic Sky and Ultra Dynamic Weather packs
Not a fit when
- The project runs on Unity or Godot: the skills are entirely about Unreal Engine
- The agent needs click-by-click editor steps: the skills contain none
- The engine is much older than 5.x: the skills target 5.8 APIs
Example request
Use the ue-gameplay-ability-system skill and add a dash ability with a cooldown to the character on GASLimitations
- The target engine is 5.8, and examples and reference paths assume it. For 5.7 the author keeps a separate install only for version diffing.
- Skills cite the engine source on disk, and the README paths are Windows ones (`E:\Program Files\Epic Games\UE_5.8`). The root can be set with `UE_ENGINE_ROOT`.
- The Ultra Dynamic Sky and Weather skills assume paid marketplace packs and rely on their documentation and asset paths.
- The README has no install command: copy the skill folders you need by hand. After an update, replace old copies because the folders gained the `ue-` prefix.
How to disable. Delete the copied `ue-*` folders from the agent's skills directory. The set leaves nothing else behind.
FAQ
How do I add unreal-engine-skills to Claude Code?
Clone the repository and copy the folders you need from `skills/` into the project's `.claude/skills/` or `~/.claude/skills/`. Folder names match the `name` field in `SKILL.md`, so the agent finds a skill by its description.
What topics do the skills cover?
C++ and reflection, modules and build, memory and GC, delegates, subsystems, Enhanced Input, GAS, Blueprints, assets, materials, animation, Control Rig, MetaHuman and the Ultra Dynamic Sky and Weather packs.
Do I need access to the engine source?
It helps: the skills cite real paths under `Engine/Source` and the agent cross-checks APIs against them. The root is set with `UE_ENGINE_ROOT`, and `scripts/check-citations.mjs` verifies that cited files exist.
How is it different from other Unreal sets?
These are pure engine knowledge with no editor control: the agent brings its own tooling, such as an MCP bridge to a live editor. Coverage is wide and includes MetaHuman and the paid sky and weather packs.
How can I tell whether a skill helps?
`evals/tasks/` holds golden tasks such as a GAS dash or replicated health. Run the agent with and without the set and compare the output against the acceptance criteria.

README in short
The README names an autonomous agent as the reader and lists the environment: Unreal Engine 5.8 and the engine source on disk. Then come the repository layout, an index of dozens of skills by group with statuses, a section on Ultra Dynamic pack skills, the `ue-` folder rename rules, authoring conventions, spec validation and the golden tasks.
