What is unreal-asset-operation?

A skill for finding and managing assets in Unreal Engine, the game and 3D development platform. It works through UCP, a protocol for communicating with the Unreal Editor.

Use it to search assets, inspect dependencies and referencers, get selected assets, open or close asset editors, and create, update, rename, or delete assets.

It gives an agent a defined way to inspect asset relationships and perform editor asset operations while the required Unreal setup is running.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00055	$0.04175
Opus 5.5	$0.00022	$0.01670

Security

Grade A, and why

unreal-asset-operation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Unreal Asset Operations

Operate on Unreal Engine assets through UCP's call command. The core approach is to obtain the IAssetRegistry instance and call its rich API directly, combined with engine asset libraries for CRUD operations.

Prerequisite: The unreal-client-protocol skill must be available and the UE editor must be running with the UCP plugin enabled.

Custom Function Library

UAssetEditorOperationLibrary (Editor)

CDO Path: /Script/UnrealClientProtocolEditor.Default__AssetEditorOperationLibrary

Function	Params	Returns	Description
`GetAssetRegistry`	(none)	`IAssetRegistry` object	Returns the AssetRegistry instance. Call its functions directly via UCP `call`.
`ForceDeleteAssets`	`AssetPaths` (array of string)	`int32` — number deleted	Force-deletes assets ignoring references. Wraps `ObjectTools::ForceDeleteObjects`.
`FixupReferencers`	`AssetPaths` (array of string)	`bool`	Cleans up redirectors left after rename/consolidate. Wraps `IAssetTools::FixupReferencers`.

Getting the AssetRegistry

{"object":"/Script/UnrealClientProtocolEditor.Default__AssetEditorOperationLibrary","function":"GetAssetRegistry"}

The returned object path can then be used as the object parameter for subsequent calls to IAssetRegistry functions.

Alternatively, you can use the engine helper directly:

{"object":"/Script/AssetRegistry.Default__AssetRegistryHelpers","function":"GetAssetRegistry"}

Force-deleting assets

{"object":"/Script/UnrealClientProtocolEditor.Default__AssetEditorOperationLibrary","function":"ForceDeleteAssets","params":{"AssetPaths":["/Game/OldAssets/M_Unused","/Game/OldAssets/T_Unused"]}}

Fixing up redirectors

After renaming or consolidating assets, redirectors may be left behind. Use FixupReferencers to resolve them:

{"object":"/Script/UnrealClientProtocolEditor.Default__AssetEditorOperationLibrary","function":"FixupReferencers","params":{"AssetPaths":["/Game/Materials/M_OldName"]}}

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
