unity-asset

A workflow for managing Unity project assets, such as scenes, prefabs, scripts, and data files. It examines dependencies, references, prefabs, and installed packages.

In plain words
What is it for?
Use it to inspect assets, list what they use and what uses them, create prefabs or data objects, and add or remove Unity packages.
Why use it?
It helps find broken references, understand which files depend on each other, and avoid removing or changing assets that other parts of the project need.

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.

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.

Security

Grade A, and why

unity-asset 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.

What it actually says

unity-asset

PREREQUISITE: ../unity-shared/SKILL.md(Relay Server 経由で Unity Editor が起動/アクティブであること)

skill 経由のコマンドは必ず -i <instance> を付ける (unity-shared #インスタンス指定)。

調査フロー

1. アセット情報   u -i <instance> asset info <path>
2. 依存関係      u -i <instance> asset deps <path>
3. 参照元        u -i <instance> asset refs <path>
4. 問題検出 → 修正 → /unity-verify

コマンド

アセット操作

u -i <instance> asset info "Assets/Prefabs/Player.prefab"    # 基本情報
u -i <instance> asset deps "Assets/Prefabs/Player.prefab"    # 依存先一覧
u -i <instance> asset refs "Assets/Prefabs/Player.prefab"    # 参照元一覧
u -i <instance> asset prefab "Assets/Prefabs/X.prefab" --target "X"  # Prefab 化
u -i <instance> asset scriptable-object "Assets/Data/Config.asset" --type "GameConfig"

パッケージ管理

u -i <instance> package list                           # インストール済みパッケージ
u -i <instance> package add com.unity.inputsystem      # 追加
u -i <instance> package remove com.unity.inputsystem   # 削除

CLI 非対応操作

unity-shared のフォールバック順に従う:

  1. u -i <instance> api schema --type AssetDatabase で対応メソッドを検索 (107メソッド)
  2. u -i <instance> api call で実行
  3. .meta インポート設定は YAML 直接編集

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.
