UE Gameplay Tags and Messaging

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

Gameplay Tags are a built-in runtime module, not a plugin: add "GameplayTags" to PublicDependencyModuleNames in your Build.cs and include GameplayTagContainer.h / NativeGameplayTags.h / GameplayTagsManager.h. This skill owns tag definition (native and ini), FGameplayTag, FGameplayTagContainer, FGameplayTagQuery, UGameplayTagsManager, editor filtering, and decoupled gameplay messaging — including the AsyncMessageSystem plugin (Experimental in 5.8).

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.
