vrc-udon-ui-menu

vrc-udon-ui-menu is a skill for Codex from sechiro/VRCUdonSkills-for-Codex. It costs 116 tokens per session (557 once invoked), scanned A, original, MIT.

A design and implementation guide for menus and world-space interfaces in VRChat UdonSharp. It covers fixed and handheld interfaces, page changes, closing and back navigation, and differences between desktop and VR controls.

In plain words
What is it for?
Use it to design page transitions, handheld or pickup-linked interfaces, close and back behavior, and the separation between pickup and UI interaction areas.
Why use it?
It prevents confusing navigation, input conflicts, and inconsistent display state when the same interface must work for different VRChat input modes.

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00116 $0.00557
Opus 5.5 $0.00046 $0.00223
Sonnet 5.5 $0.00023 $0.00111
Haiku 4.5 $0.00012 $0.00056

Measured 2mo ago against content hash 32cd004be19a, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

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 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.

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

  1. references/menu-patterns.md を読む。
  2. UI が固定設置か、手持ちか、Pickup 連動かを最初に決める。
  3. 画面遷移は公開メソッド名を揃える。
  4. 画面の正本は 1 つの Controller に寄せる。
  5. 入力差は Desktop / VR で分けて考える。
  6. 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
Files

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.

Changes

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.
