Also use when the user mentions 'UE C++', 'garbage collection', 'CDO', 'smart pointers' or 'specifiers'.

SKILL.md

UE C++ Foundations

Target engine: UE 5.8. APIs below are verified against the 5.8 headers; older forms are listed under "Deprecated — do not use".

This skill covers the C++ layer every Unreal module is built on: reflection macros (UCLASS, UPROPERTY, UFUNCTION, USTRUCT, UENUM, UINTERFACE), containers, delegates, string types, object lifetime and garbage collection, CDO access, and the subsystem family. All of it lives in the Core, CoreUObject and Engine modules (PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine" });). Editor subsystems additionally need EditorSubsystem and UnrealEd in an editor-only module.

Context

Read .agents/ue-project-context.md if it exists (module names, conventions, enabled plugins, GAS/networking setup). Do not stop if it is missing.

Identify the area from the request and the codebase. Ask only when two plausible readings would produce different code.
