Use when implementing save/load systems, player progress persistence, or data serialization in Unreal Engine. Triggers on: save game, USaveGame, FArchive, serialization, SaveGameToSlot, config, persist data, save file, load game. See references/save-system-architecture.md for full slot management and multi-user patterns.
Use when implementing collision detection, trace queries, physics simulation, or physical interactions in Unreal Engine. Triggers on: 'collision', 'trace', 'LineTrace', 'line trace', 'overlap', 'physics', 'hit result', 'sweep', 'collision channel', 'physics body', 'Chaos', 'raytrace', 'OnHit', 'OnBeginOverlap'. See related skills for component architecture and AI navigation.
Use when working with DataAsset, DataTable, soft reference, hard reference, TSoftObjectPtr, async loading, Asset Manager, StreamableManager, or game data structures in Unreal Engine. See references/asset-loading-patterns.md for async loading and StreamableManager patterns. See references/data-driven-design.md for data-driven gameplay architecture. For serialization, see ue-serialization-savegames. For C++ foundations, see ue-cpp-foundations.
Use when writing automation tests, functional tests, or any test in Unreal Engine. Also use when the user asks about "UE_LOG", logging, log categories, assertion, check, ensure, verify, DrawDebug, debug draw, console command, profiling, Unreal Insights, stat commands, or debugging techniques. See ue-module-build-system for test module setup, and ue-cpp-foundations for general C++ logging patterns.
Use this skill when working with Unreal Engine's gameplay framework classes: GameMode, GameState, PlayerController, PlayerState, Pawn, Character, or GameInstance. Also use when the user mentions 'gameplay framework', 'game rules', 'player management', 'match flow', or 'player spawning'. See references/framework-class-map.md for the full authority/presence matrix. For networking/replication, see ue-networking-replication. For input setup, see ue-input-system.
Use this skill when implementing player input with Unreal Engine's Enhanced Input system. Also use when the user mentions 'Enhanced Input', 'input', 'input action', 'InputAction', 'mapping context', 'InputMappingContext', 'input binding', 'key binding', 'input trigger', 'input modifier', 'gamepad', or 'keyboard'. Covers ETriggerEvent, built-in triggers (Hold, Tap, Pulse, ChordAction, Combo), built-in modifiers (DeadZone, Scalar, Negate, SwizzleAxis), and custom trigger/modifier authoring. See references/input-action-reference.md for the full catalogue. For UI input modes, see ue-ui-umg-slate.
Use this skill when working with Mass Entity, MassEntity, Mass AI, MassProcessor, MassFragment, MassTag, MassObserver, MassSpawner, MassCrowd, Mass ECS, entity archetype, ForEachEntityChunk, FMassEntityQuery, FMassEntityManager, ISM crowd, or large-scale entity simulation in Unreal Engine. See references/mass-entity-patterns.md for processor and observer templates. See references/mass-fragment-reference.md for built-in fragment types.
Use this skill when working with UMG, UI, widget, UserWidget, Slate, HUD, BindWidget, Common UI, menu, or UMG binding in Unreal Engine. See references/widget-types.md for widget type reference and references/common-ui-setup.md for Common UI plugin setup. For Slate in editor tools, see ue-editor-tools. For input mode management, see ue-input-system.
Use this skill when working with World Partition, level streaming, level travel, OpenLevel, ServerTravel, data layer, world subsystem, level instance, sub-level, seamless travel, open world, or HLOD. See references/streaming-patterns.md for configuration patterns by game type.
Use when the user is working with material, shader, MID, dynamic material, material instance, post-process, render target, parameter collection, decal, Nanite, Lumen, or rendering in Unreal Engine. See references/material-parameter-reference.md for parameter patterns and references/post-process-settings.md for post-process settings. For particle rendering, see ue-niagara-effects.
Use when working with Build.cs, Target.cs, module creation, plugin setup, or build errors in Unreal Engine — including "unresolved external symbol," "cannot open include file," IWYU violations, missing API macros, or dependency configuration. See also ue-cpp-foundations for UObject macro patterns.
When the user wants to create or update their Unreal Engine project context document. Use when the user says 'project context,' 'set up context,' 'UE context,' 'configure project,' or wants to avoid repeating their project setup across UE development tasks. Creates `.agents/ue-project-context.md` that all other UE skills reference. See related skills footer for skills that depend on this context.
