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 | $0.00194 | $0.01155 |
| Opus 5 | $0.00097 | $0.00577 |
| Sonnet 5 | $0.00039 | $0.00231 |
| Haiku 4.5 | $0.00019 | $0.00115 |
Grade A, and why
flutter-layered-architecture-design-patterns 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 10d 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.

Flutter-Layered-Architecture / デザインパターン
Usecase 層・Data（Repository）層の 定番実装パターン を適用する。
レイヤー全体の地図は flutter-layered-architecture-design、本 SKILL はパターン詳細。
いつ使うか
- Usecase / Repository のインターフェース・実装を新規作成・改修するとき
- Request / Result（必要なら sealed Request）の形を決めるとき
- Repository と Usecase の相互依存を設計するとき
いつ使わないか
- どのレイヤーに置くかだけ →
flutter-layered-architecture-design - 画面 MVVM の実装手順 →
flutter-layered-architecture-screen-mvvm - 既存コードの所在調査 →
flutter-layered-architecture-code-search - extension type / コメント規約など言語面だけ →

作業手順
- 対象が Usecase か Repository かを決める
- 下の原則で IF / 命名 / Request・Result を決める
- 詳細は対応する
references/だけ読む - Riverpod の
Provider.dependenciesでクラス循環を避ける
Usecase パターン（要約）
- 1 インターフェース = 1 機能。メソッドは原則
execute()のみ（他名は例外扱い） - 命名は新規
{動詞}{カテゴリ}Usecase（例:SearchKanjiUsecase） - 入出力は Request / Result。複数引数パターンは sealed Request
- ステートレス（状態は Repository / Datasource 側）
- interface と実装は別 package。Riverpod Provider で結線
詳細 → references/usecase-pattern.md
Repository パターン（要約）
- 名称は
{機能グループ名}Repository - 同一機能グループなら複数メソッド可（Usecase の 1 機能原則とは違う）
- Read/Write・監視（
watch/Stream）を窓口として抽象化してよい - 入出力は Request / Result を基本とする
- interface / 実装は別 package。注入は DataInjection 等で一元化することが多い
詳細 → references/repository-pattern.md
Repository ↔ Usecase の依存
- usecase と data は同レベルのため、相互のインターフェース依存は可
- クラス循環は不可。
Provider.dependenciesを把握して組む - 実装 package 同士の密結合や、公開 IF への SDK リークを避ける
追加ドキュメント
| 参照 | 使うとき |
|---|---|
| usecase-pattern.md | Usecase IF・実装・Request/Result・package internal Usecase |
| repository-pattern.md | Repository IF・実装・監視・命名・テスト差し替え |
ナレッジベース
DO: Usecase は細かく切る、Repository は機能グループでまとめる
- Usecase を肥大化させず、Repository にデータ操作を寄せすぎない／散らしすぎないバランスを取る
- Repository / 画面の Delegate 共通処理は package internal Usecase に切る（Delegate in Delegate 禁止）
DO: 公開面は interface、詳細は実装 package
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.
- 10d ago First seen · 87 lines · 194 tokens per session scan A d2d4ab2fe914
flutter-layered-architecture-design-patterns is a skill published in the GitHub repository eaglesakura/agent-skills (2 stars, last pushed 5d ago), licensed MIT. It adds 194 tokens to every session and 1,155 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
