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 | $0.00200 | $0.01309 |
| Opus 5 | $0.00100 | $0.00655 |
| Sonnet 5 | $0.00040 | $0.00262 |
| Haiku 4.5 | $0.00020 | $0.00131 |
Grade A, and why
flutter-monolith-localization 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 7d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
monolith / L10n 対応
Flutter アプリで、monolith 経由のローカライゼーション(CSV → 生成コード)を扱うときはこの SKILL に従う。
実装の細部・DO/DO NOT は references/localization.md を読む。
コマンド例は dart run … 本体で示す。mise / fvm 等のラッパーはリポジトリ規約に任せ、本 SKILL には埋め込まない。
いつ使うか
res/strings.csvへの文言追加・変更dart run monolith_runner:localizationによるコード生成- パッケージ内
stringsアクセサ(L10nStringsMixin)の実装 - Unit Test / Widget Preview / Golden Test への文言注入(
StringsTestHelper)
いつ使わないか
- Flutter 標準
gen-l10n/ ARB 手編集のみ(monolith を使わない場合) - Dart の一般的なコーディング規約だけ →
flutter-coding-rules - アプリ起動・DTD デバッグ →
flutter-app-debug
データレイアウト
各 package ごと(必要に応じて):
path/to/package
├── lib
│ ├── gen
│ │ └── strings.dart # 自動生成(手編集しない)
│ └── src
│ └── strings.dart # 手書き: L10nStringsMixin を mixin
├── pubspec.yaml
├── res
│ └── strings.csv # 真実源
└── test
集約言語の正本(ARB / gen-l10n / L10nHelper)は app_runner(app/runner) に出力される。
feature アプリは package:app_runner/app_runner.dart 経由で L10nHelper を利用する。
.secrets/monolith.secrets.yaml に localization.app.package_name がある場合は app_runner に揃える(secrets が優先)。
作業手順
res/strings.csvを編集する(ヘッダーid,{言語コード},description)- ルートから生成する:
dart run monolith_runner:localization - パッケージの
lib/src/strings.dartで生成 mixin を使う(exportしない、@internal) - テスト/Preview が必要なら
StringsTestHelper+LocalizeStringDelegate.injectDelegateForTest
依存ライブラリ
| パッケージ | 置き場所 |
|---|---|
| monolith | dart workspace ルートの dev_dependencies |
| monolith_localization | 同上 |
| monolith_localization_runtime | 個別 package に必要 |
個別 package に monolith / monolith_localization を足す必要はない。
StringsTestHelper(Test / Preview / Golden)
monolith.yaml の localization.test_helper は省略可。省略時はヘルパーを生成しない。
localization:
languages:
- ja
test_helper:
package_name: foundation_resources # required
test_helper_class_name: StringsTestHelper # optional
test_helper_path: lib/gen/strings_test_helper.dart # optional
What ships with it
1 file 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.

flutter-monolith-localization is a skill published in the GitHub repository eaglesakura/agent-skills (2 stars, last pushed 2d ago), licensed MIT. It adds 200 tokens to every session and 1,309 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.
