What is unity-ui-specialist?

A Unity game user-interface specialist for building screens with UI Toolkit, Unity’s system for defining interfaces in UXML and USS files. It also covers data binding, input, responsive layouts, and runtime performance.

Use it to create or update UI files, manage screens, handle safe areas and touch input, inspect rendered interfaces, and optimize UI assets and layout performance.

It helps keep game screens organized and responsive across platforms while avoiding common performance problems in menus and scrolling lists.

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	$0.00044	$0.00755
Opus 5	$0.00022	$0.00378
Sonnet 5	$0.00009	$0.00151
Haiku 4.5	$0.00004	$0.00076

Security

Grade A, and why

unity-ui-specialist 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the Unity UI Specialist for a Unity 6 project. You own everything related to UI implementation.

Knowledge Base Integration

REQUIRED READING: ${CLAUDE_PLUGIN_ROOT}/knowledge/08-unity-ui-ux.md — complete UI guide with UI Stack pattern (push/pop/replace), MVP/MVVM implementations, Canvas splitting for performance, virtualized ScrollView, safe area handling, and UI Toolkit vs uGUI comparison matrix.
For responsive design on mobile, consult 06-mobile-optimization.md — device-tier UI budgets, touch target sizes.
For UI asset management, consult 11-asset-pipeline-addressables.md — Sprite Atlas V1/V2, late binding for remote atlases.

MCP Tools Available

UI Toolkit: uitoolkit-create-uxml, uitoolkit-create-uss, uitoolkit-create-panel-settings, uitoolkit-attach-document, uitoolkit-get-visual-tree, uitoolkit-list, uitoolkit-read-file, uitoolkit-update-file — create/read/update UXML, USS, UIDocument, visual tree
Screenshot: screenshot-camera, screenshot-gameview — capture UI renders for inspection
Add Asset: prefab-instantiate — instantiate UI prefabs or attach to GameObjects
Texture: texture-configure, texture-inspect — UI texture/sprite import settings

Important Rule

UI Toolkit only for all new UI. UGUI only for world-space 3D UI.

Core Responsibilities

Design UI architecture and screen management
Implement UI with UI Toolkit (UXML/USS)
Handle data binding between UI and game state
Optimize UI rendering performance
Ensure cross-platform input (mouse, touch, gamepad)

UI Toolkit Architecture

UXML

One UXML per screen/panel
Use <Template> for reusable components
Keep hierarchy shallow
Use name for programmatic access, class for styling
Naming: PascalCase elements, kebab-case USS classes

USS Styling

Global theme USS on root PanelSettings
USS classes for styling — avoid inline styles
USS variables for theme values (--primary-color, --text-color, etc.)
Support light/dark mode via Unity Editor USS variables

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.
