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 | $0.00071 | $0.04079 |
| Opus 5 | $0.00036 | $0.02039 |
| Sonnet 5 | $0.00014 | $0.00816 |
| Haiku 4.5 | $0.00007 | $0.00408 |
Grade A, and why
unity-ui 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 2d 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 unity-ui — 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 — 487 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unity UI Systems
Unity provides three UI frameworks. UI Toolkit is the recommended system for new projects. uGUI remains supported for legacy and certain runtime use cases. IMGUI is strictly for Editor tooling and debugging.
UI System Comparison
| Feature | UI Toolkit | uGUI (Canvas) | IMGUI |
|---|---|---|---|
| Recommended for new projects | Yes | No (legacy) | No |
| Runtime game UI | Yes | Yes | Not recommended |
| Editor extensions | Yes | No | Yes |
| Approach | Web-inspired (UXML + USS + C#) | GameObject + Component | Code-only (OnGUI) |
| Layout system | Flexbox (Yoga) | RectTransform + Anchors | Immediate mode |
| Styling | USS stylesheets | Per-component properties | GUIStyle / GUISkin |
| Visual authoring | UI Builder | Scene View | None |
| Performance | Optimized retained mode | Canvas batching | Redraws every frame |
| Data binding | SerializedObject + Runtime binding | Manual via code | Manual via code |
| World-space UI | Supported | Canvas World Space mode | Not supported |
| Input integration | Pointer/Keyboard events | EventSystem + Raycasters | Event.current |
Decision guide:
- New runtime UI (menus, HUD, inventory) --> UI Toolkit
- New Editor windows / inspectors --> UI Toolkit
- Existing project with uGUI --> Continue with uGUI, migrate incrementally
- Quick debug overlays in Editor --> IMGUI
- World-space UI on 3D objects --> Either UI Toolkit or uGUI World Space Canvas
UI Toolkit
UI Toolkit is Unity's modern UI framework inspired by web technologies. It uses UXML for structure, USS for styling, and C# for logic.
Core Architecture
UIDocument (MonoBehaviour on GameObject)
--> VisualTreeAsset (.uxml) -- defines structure
--> StyleSheet (.uss) -- defines appearance
--> C# script -- defines behavior
All UI elements inherit from VisualElement. The root is accessed via rootVisualElement.
UXML Structure
UXML defines the UI hierarchy declaratively:
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.

unity-ui is a skill published in the GitHub repository IdoCohen560/claude-unity-game-studio (17 stars, last pushed 1mo ago), licensed MIT. It adds 71 tokens to every session and 4,079 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to unity-ui, differing in 0 lines, and is treated as a copy.
Other skills, from other repositories
swarm
Run a multi-agent audit of a codebase by spawning specialized parallel subagents (security, performance, tests, architecture, dead-code), then synthesize their findings into a single prioritized action plan. Use this whenever the user runs /swarm, asks to "audit the repo," "review this codebase," "find issues across…
memory-loop-setup
Bootstrap the memory loop into any repo or Obsidian vault. Triggers: (1) "set up the memory loop / second brain / warm layer here" or "install this structure in another repo/vault", (2) a new project asking "make the AI remember across sessions and surfaces".
discord-intent-application
Helps write the justification text for Discord Developer Portal privileged intent applications (Message Content, Server Members, Presence) for a specific bot. Takes a plain-text description of the bot's functionality and/or an uploaded/local codebase, screens the bot's features against Discord's known rejection…
plan-qa
Post-implementation QA planning — independent of /review (the developer chooses whether to run them sequentially or in parallel), only when the change has a running surface worth driving. Interviews the developer to turn the specs and the diff into an executable QA specification (specs/qa/QA- - .md) that /execute-qa…
review
Phase 5 of 5 — triage-first review orchestrator; dispatches up to 17 domain checks in parallel and compiles one report. Use only when the user asks to run Phase 5 or review a PR, branch, or set of changes — never trigger automatically after writing code.
session-audit
Audit Claude Code session logs (/.claude/projects) for token waste and produce a ranked, attributed efficiency report (habit / skillfile / config). Use when the user asks to audit session efficiency, analyze token waste or cost blowups, review Claude Code usage cost, or asks "where are my tokens going".
