What is floatsoda-device-test?

A testing process for FloatSoda features that require SteamVR and a headset, plus behaviours that differ from the Flutter library it follows. SteamVR is the software that runs compatible virtual-reality headsets.

Use it to list VR-only and Flutter-comparison scenarios, decide which belong in automated xUnit tests or headset testing, build the headset test harness, and investigate failures.

Ordinary automated tests cannot cover headset-only behaviour such as controller rays, overlay events, or graphics running on the render thread. The process also exposes differences that could otherwise be mistaken for bugs or intended design choices.

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	$0.00286	$0.03920
Opus 5	$0.00143	$0.01960
Sonnet 5	$0.00057	$0.00784
Haiku 4.5	$0.00029	$0.00392

Security

Grade A, and why

floatsoda-device-test 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.

FloatSoda デバイステスト

このスキルが存在する理由

FloatSoda には 84 のテストファイルがあるが、WidgetBinding を一気通貫で駆動しているのはそのうち 2つ(tests/FloatSoda.Test/Core/PointerInputIntegrationTest.cs と tests/FloatSoda.Test/Core/WidgetBindingTest.cs)だけ。src/FloatSoda.OVR と src/FloatSoda.Engine は事実上テストされていない。SteamVR が稼働しているときにしか存在しないもの — オーバーレイハンドル、コントローラーレイの座標、レンダースレッド上の GL コンテキスト、ダッシュボードの開閉イベント — にはカバレッジが一切なく、dotnet test から得る手段もない。

それとは別に、FloatSoda は Flutter の三層ツリーモデルを鏡写しにしており、docs も Flutter の語彙で概念を教えている。そのため利用者(と、利用者のために書く LLM)は Flutter の挙動を期待してやって来る。移植が乖離している箇所では、乖離がバグでも意図的な設計判断でも、利用者が払うコストは同じ。 だから移植差異は、VR 専用の欠陥クラスと並べて列挙する価値のある、それ自体独立した欠陥クラスになる。

このスキルは、この両方を場当たりな VR セッションではなく反復可能なプロセスにする。

以下のすべてを規定する経済性

デバイス実行はこのプロジェクトで最も高価なテスト。HMD を被り、SteamVR を起動し、手で操作し、目で判定する。だから:

網羅性は列挙の段階で達成する。実行は意図的に絞る。

この2つを同じサイズにしないこと。40 シナリオを列挙して 34 をヘッドレス xunit に、6 を HMD に振り分けられたら、それは不足ではなく成功。

オーケストレーションとハードストップ

Claude Code が主導する: Codex への brief の作成、Codex の報告内容の検証、振り分け、ハーネスの構築、失敗のトリアージ、Issue の起票。

次の3つはオーナーだけのもの:

VR での実行 — 物理的に委任できない。
最終的な設計判断 — 差異を受け入れるか修正するか。
コミット / push / タグ — 必ず確認を取る。

Issue の起票に確認は不要(リポジトリの既存慣行)。ただしここは公開リポジトリなので、デバイステストのログやスタックトレースを Issue に貼る前に、リポジトリ自身の規約が求めるとおり、ローカル環境の情報 — 絶対パス、マシン名、ユーザー名 — を取り除くこと。

ワークフロー

1. 列挙する — Codex に委任、2つの軸で

brief には references/codex-enumeration-prompt.md を使う。task-codex-subagent スキル (subagent_type: "codex-runner")でバックグラウンド起動し、読み取り専用の意図で実行する: Codex が書くのはちょうど1ファイル(スクラッチパッド内のシナリオリスト)だけで、リポジトリには何も触れない。コードもテストも書かせない。

brief には必ず次を含める:

軸A — VR 専用: オーバーレイのライフサイクル、コントローラーポインタの座標、デバイストラッキング、SteamVR イベント、アクションマニフェスト、GL コンテキスト / レンダースレッド / フレームペーシング。
軸B — Flutter 移植差異: Elements/、RenderObjects/RenderObject.cs、Core/WidgetBinding.cs、 Gesture/ を、~/code_reading/flutter_reference の Flutter クローンと突き合わせる。 references/known-divergences.md を渡し、再発見ではなくリストの拡張をさせる。
既知 Issue の除外リスト(後述)。起票済みバグの再発見に列挙の労力を使わせないため。
シナリオごとの必須フィールド: 識別子(--scenario 引数に使える形)/ 壊れる理由の仮説 / file:line / HEADLESS か VR かとその根拠 / 再現手順 / 期待結果。軸B のエントリには対応する Flutter 本家実装のファイルパスも併記する。
ハルシネーション対策の条項: すべての file:line は実際にファイルを読んだ結果であること。未確認のものはその旨を明記させる。

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.
