Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00057 | $0.01068 |
| Opus 5 | $0.00028 | $0.00534 |
| Sonnet 5 | $0.00011 | $0.00214 |
| Haiku 4.5 | $0.00006 | $0.00107 |
Grade A, and why
ue5-ui-umg-slate 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 12d 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.
This is a copy
100% identical to ue5-ui-umg-slate — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Quick Start
- Identify whether feature belongs to UMG, Slate, or hybrid bridge.
- Define data source component/subsystem and UI binding point.
- Output widget tree intent and runtime binding sequence.
UE5.7 API Anchors
- UMG lifecycle and viewport anchors:
UUserWidget::NativeConstruct(),UUserWidget::NativeDestruct()UUserWidget::AddToViewport(...)UWidget::RemoveFromParent()UWidget::SetVisibility(...)UWidget::SetKeyboardFocus()
- UMG input mode anchors:
UWidgetBlueprintLibrary::SetInputMode_UIOnlyEx(...)UWidgetBlueprintLibrary::SetInputMode_GameAndUIEx(...)UWidgetBlueprintLibrary::SetInputMode_GameOnly(...)
- UMG/Slate bridge anchors:
UWidget::TakeWidget()for Slate bridge hand-offSCompoundWidget,SLATE_BEGIN_ARGS(...)FSlateApplication::SetKeyboardFocus(...),SetUserFocus(...)
- Viewport geometry anchor:
UGameViewportClient::GetViewportSize(...)
UI Stage Contract
- Every UI task must define:
- UI layer ownership (UMG-only, Slate-only, or hybrid bridge)
- data source and update trigger (pull, push, event, or mixed)
- focus and input ownership transition
- viewport-safe placement behavior for tooltip/popup
- teardown/cleanup path for unbinds and widget removal
- If any item is missing, the UI implementation is incomplete.
Workflow
1) UI Architecture Decision
- Select UMG for standard game HUD/menu work.
- Select Slate for custom rendering/input behavior that UMG cannot express cleanly.
- Select hybrid when a
UWidgethost needs to embed custom Slate content.
2) Construct and Lifetime
- Initialize widget bindings in construct/init path.
- Register event listeners once and store handles when required.
- Define destruct/unregister logic explicitly to avoid stale bindings.
3) Data Binding and Refresh
- Bind runtime data from one authoritative source (subsystem/component/view model).
- Use event-driven refresh for high-frequency data where possible.
- Keep display widgets read-only for gameplay state mutation.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ue5-ui-umg-slate is a skill published in the GitHub repository teixasalone/UnrealEngine5-Skills (17 stars, last pushed 2d ago), licensed MIT. It adds 57 tokens to every session and 1,068 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to ue5-ui-umg-slate, differing in 0 lines, and is treated as a copy.
Other skills, from other repositories
3d_object
Judge whether a generated mesh is fit to ship in a browser game, from the same rendered sheet the orientation review uses.
3d_scene
Choose how to build a 3dscene asset. Do not default to one pipeline for every task: what the user specified about the scene's appearance matters more than the scene type, and generative reconstruction is the least stable route here.
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
audio
Use this Skill when a game plan requires dialogue, voice lines, sound effects, foley, ambience, or other offline WAV assets. This is asset generation, not a runtime audio-playback contract; use the selected engine context after an asset has passed review.
image
Use this Skill when a game plan needs a single-subject concept image, a character reference cleaned for image-to-3D, or a front-facing transparent T-pose image for downstream character reconstruction. T-pose generation is an image-generation and image-editing task; it is not a separate asset category.
game-cg-director
Convert game CG intent and optional media references into validated, model-specific directing envelopes for opening, cutscene, ultimate, or promo clips. Use for standalone CG prompt direction or as a child capability of a game-generation Harness. Supports T2VA/text-only, I2VA/first-frame image…
