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 | $0.00197 | $0.01926 |
| Opus 5.5 | $0.00079 | $0.00770 |
| Sonnet 5.5 | $0.00039 | $0.00385 |
| Haiku 4.5 | $0.00020 | $0.00193 |
Grade A, and why
flutter-layered-architecture-screen-mvvm 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.
How it starts
The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Flutter / Screen 層 MVVM
Screen 層の画面を Model–View–ViewModel で組む。状態は ViewModel、表示は Entity、操作は onXXXX()、見た目は Widget。
詳細は文脈に応じて references/ だけ追加ロードする（本 SKILL は地図と原則）。
いつ使うか
- 新規／改修で Screen の ViewModel・State・Entity・Event・Widget を設計するとき
- アクション（
onXXXX/ Delegate）や ViewModel Unit Test を書くとき - Riverpod での ViewModel DI・ライフサイクル（autoDispose）を揃えるとき
いつ使わないか
- 画面遷移・
*Factory/*Launcher/go_router隠蔽 →flutter-layered-architecture-screen-navigation - Usecase / Repository の Request&Result 定番だけ →
flutter-layered-architecture-design-patterns - どのレイヤーに置くかだけ →
flutter-layered-architecture-design - 既存コードの所在調査 →
flutter-layered-architecture-code-search - 言語規約だけ →
flutter-coding-rules
作業手順
- 対象が ViewModel / State・Entity・Event / Action / View(Widget) / Test のどれかを決める
- 下の原則で骨格を決める
- 詳細は対応する
references/だけ読む（全部を一度に読まない） - 画面遷移が必要なら
screen-navigationに委ねる（本 SKILL ではルーター直叩きしない）
原則（要約）
- 1 画面 = 1 ViewModel（タブ親子など、スコープが互いに素なら柔軟に）
- ViewModel は
@internal、private コンストラクタ、static final provider = Provider.autoDispose<...>（@riverpodは使わない） - Riverpod は DI とライフサイクルに限る。全フィールド
final。可変状態はMutableStateStream<ScreenState>のみ - 表示は
StateStream<ScreenEntity> entity（State→Entity は Delegate）。ワンショットはStream<ScreenEvent> event - Widget からの操作はすべて
onXXXX()拡張（onInitialize含む）。本体は.action.dartの part + 使い捨てOnXxxxxDelegate（execute） - ルート Widget は
{画面名}Screen（public）で VM watch／初期化／event 購読。見た目は{画面名}ScreenImpl。配下は Entity のみ watch、操作時はref.read
主なライブラリ
| 用途 | パッケージ |
|---|---|
| 状態・DI | flutter_riverpod / hooks_riverpod / flutter_hooks |
| State ストリーム | state_stream / state_stream_riverpod |
| 深い比較 watch | flutter_riverpod_watch_plus（watchBy） |
| 不変データ | freezed（State / Entity / Event） |
| VM テスト | riverpod_container_async_test 等 |

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.

flutter-layered-architecture-screen-mvvm is a skill published in the GitHub repository eaglesakura/agent-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 197 tokens to every session and 1,926 once invoked, about $0.0008 per session on Opus 5.5. 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.
