1	# UE Editor Tools
2
3	You are an expert in extending the Unreal Editor with custom tools and workflows.
4
5	## Context
6
7	Read `.agents/ue-project-context.md` for editor module structure, engine version, team workflows, and project-specific conventions before providing guidance.
8
9	## Before You Start
10
11	Ask which area the user needs if not clear:
12	- Editor Utility Widget — UMG panel run from editor right-click
13	- Blutility — UAssetActionUtility or UActorActionUtility scripted actions
14	- Detail Customization — Custom property panel (IDetailCustomization / IPropertyTypeCustomization)
15	- Custom Editor Mode — Viewport mode with specialized interaction (FEdMode)
16	- Asset Type Actions — Content Browser integration for a custom asset type
17	- Editor Subsystem — Editor-lifetime singleton (UEditorSubsystem)
18	- Menu / Toolbar Extension — UToolMenus additions to main menu, toolbars, context menus
19

21
22	## Editor Module Setup
23
24	All editor-extending code must live in a module with `"Type": "Editor"`. Never put `UnrealEd` / `PropertyEditor` includes in a Runtime module without `#if WITH_EDITOR` guards.
25
26	```json
27	{ "Name": "MyGameEditor", "Type": "Editor", "LoadingPhase": "PostEngineInit" }
28	```
29
30	```csharp
31	// MyGameEditor.Build.cs — key dependencies
32	PrivateDependencyModuleNames.AddRange(new string[] {
33	"Core", "CoreUObject", "Engine", "UnrealEd",
34	"Slate", "SlateCore", "EditorStyle",
35	"PropertyEditor", // IDetailCustomization, IPropertyTypeCustomization
36	"EditorSubsystem", // UEditorSubsystem
37	"Blutility", // UEditorUtilityWidget, UAssetActionUtility
38	"ToolMenus", // UToolMenus
39	"AssetTools", // FAssetTypeActions_Base
40	"MyGame"
41	});
42	```
43	Module skeleton — every registration in `StartupModule` must be mirrored in `ShutdownModule`:
44	```cpp
45	IMPLEMENT_MODULE(FMyGameEditorModule, MyGameEditor)
46
47	void FMyGameEditorModule::StartupModule()
48	{
49	FPropertyEditorModule& PropMod =
50	FModuleManager::LoadModuleChecked<FPropertyEditorModule>("PropertyEditor");
51	PropMod.RegisterCustomClassLayout(
52	UMyDataAsset::StaticClass()->GetFName(),
53	FOnGetDetailCustomizationInstance::CreateStatic(
54	&FMyDataAssetCustomization::MakeInstance));
55	PropMod.NotifyCustomizationModuleChanged();
56
57	UToolMenus::RegisterStartupCallback(
58	FSimpleMulticastDelegate::FDelegate::CreateRaw(
59	this, &FMyGameEditorModule::RegisterMenus));
60	}
61
62	void FMyGameEditorModule::ShutdownModule()
63	{
64	if (FModuleManager::Get().IsModuleLoaded("PropertyEditor"))
65	{
66	FModuleManager::GetModuleChecked<FPropertyEditorModule>("PropertyEditor")
67	.UnregisterCustomClassLayout(UMyDataAsset::StaticClass()->GetFName());
68	}
69	UToolMenus::UnRegisterStartupCallback(this);
70	if (UToolMenus* TM = UToolMenus::TryGet()) { TM->UnregisterOwner(this); }
71	}
72	```

78	## Editor Utility Widgets
79
80	`UEditorUtilityWidget` (from `EditorUtilityWidget.h`) extends `UUserWidget` for editor-only UMG panels. Create as a Blueprint subclass (right-click Content Browser > Editor Utilities > Editor Utility Widget). Run: right-click the widget asset > Run Editor Utility Widget. Or subclass in C++:
81
82	```cpp
83	#pragma once
84	#include "EditorUtilityWidget.h"
85	#include "MyEditorUtilityWidget.generated.h"
86
87	UCLASS()
88	class MYGAMEEDITOR_API UMyEditorUtilityWidget : public UEditorUtilityWidget
89	{
90	GENERATED_BODY()
91	public:
92	UFUNCTION(BlueprintCallable, Category = "My Tools")
93	void BatchRenameSelectedAssets(const FString& Prefix);
94	};
95
96	// .cpp
97	void UMyEditorUtilityWidget::BatchRenameSelectedAssets(const FString& Prefix)
98	{
99	for (UObject* Asset : UEditorUtilityLibrary::GetSelectedAssets())
100	{
101	if (Asset)
102	{
103	const FString Src = Asset->GetOutermost()->GetName(); // e.g. /Game/Folder/OldName
104	UEditorAssetLibrary::RenameAsset(Src, FPaths::GetPath(Src) / Prefix + TEXT("_") + Asset->GetName());
105	}
106	}
107	}
108	```
109
110	Key `UEditorUtilityLibrary` functions (from `EditorUtilityLibrary.h`):
111
112	\| Function \| Purpose \|
113	\|---\|---\|
114	\| `GetSelectedAssets()` \| Currently selected Content Browser assets \|
115	\| `GetSelectedAssetsOfClass(UClass*)` \| Filter selection by class \|
116	\| `UEditorAssetLibrary::DeleteAsset(Path)` \| Delete asset; `RenameAsset` for move/rename \|
117	\| `GetSelectionSet()` \| Selected level actors \|
118	\| `SyncBrowserToFolders(TArray<FString>)` \| Sync content browser view \|
119
120	Content browser filters: Use `FARFilter` with `IAssetRegistry::GetAssets` for programma
