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 | $0.00116 | $0.00557 |
| Opus 5 | $0.00058 | $0.00279 |
| Sonnet 5 | $0.00023 | $0.00111 |
| Haiku 4.5 | $0.00012 | $0.00056 |
Grade A, and why
vrc-udon-ui-menu 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.
What it actually says
VRC Udon UI Menu
役割
ワールド空間 UI とメニュー導線を、VR と Desktop の両方で破綻しにくい形にまとめる。ページ切り替え、閉じる戻る、手持ち UI、Pickup と UI の関係整理を担当する。
この Skill を使う場面
- ワールド空間 UI を作る
- ページ切り替えや戻る閉じる導線を設計する
- Pickup と UI の干渉を整理したい
この Skill を使わない場面
- ネットワークの責務や同期仕様を決めるだけの場合:
vrc-udon-networking-rules - モジュールの構造設計から始める場合:
vrc-udon-core-module
進め方
references/menu-patterns.mdを読む。- UI が固定設置か、手持ちか、Pickup 連動かを最初に決める。
- 画面遷移は公開メソッド名を揃える。
- 画面の正本は 1 つの Controller に寄せる。
- 入力差は Desktop / VR で分けて考える。
- Networking が絡むなら
$vrc-udon-networking-rulesを追加で読む。
担当範囲
- UI レイアウト責務の整理
- 画面遷移イベントの整理
- Pickup と UI の干渉回避
- Desktop / VR 入力差の整理
注意点
- 表示状態の正本を複数箇所に持たない
- Pickup Collider と UI Collider の役割を混ぜない
- Close だけで戻れない画面を作らない
- 手持ち UI は姿勢崩れと誤操作を前提にする
What ships with it
2 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.
