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 | $0.00158 | $0.01512 |
| Opus 5 | $0.00079 | $0.00756 |
| Sonnet 5 | $0.00032 | $0.00302 |
| Haiku 4.5 | $0.00016 | $0.00151 |
Grade A, and why
flutter-maintenance-check-latest-version 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 11d 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 — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Flutter / 最新バージョン調査
Flutter SDK(flutter/flutter)のリリース済みバージョンと変更点を調べ、現在のローカル SDK との差を把握する。
Dart / pub 依存の更新手順そのものは対象外である(隣接 SKILL へ委ねる)。
コマンド例はツール本体(flutter / gh)で示す。mise / fvm 等のラッパーはリポジトリの AGENTS.md やローカル規約に任せ、本 SKILL には埋め込まない。
いつ使うか
- Stable 等の最新 Flutter SDK バージョンを知りたいとき
- メジャー/マイナー(例:
3.x)に絞った候補一覧が欲しいとき - 現在の
flutter --versionと対象バージョンの CHANGELOG 差分を要約したいとき
いつ使わないか
flutter pub outdatedやdependency_overridesの更新 →flutter-layered-architecture-library-update- アプリ起動・ランタイムデバッグ →
flutter-app-debug - 文言/L10n →
flutter-monolith-localization
手順概要
- ローカルの現在バージョンを把握する
flutter/flutterの tag からリリース済み候補を列挙する(必要ならメジャーで絞る)CHANGELOG.md(master)から対象バージョンの変更サマリを取る- assets/report.md の型で報告する
1. 現在バージョン
flutter --version
- Framework / Channel / リビジョンを控える
- ユーザーが「今のバージョン」を既に示していればそれを優先してよい
2. リリース済みバージョン一覧(tags)
出典: flutter/flutter
# 一覧
gh api repos/flutter/flutter/tags --paginate --jq '.[].name'
# 例: 3.x に絞る
gh api repos/flutter/flutter/tags --paginate --jq '.[].name' | rg '^3\.'
- tag 名がリリース済みバージョンの一次情報である
- 必要に応じて
rgでメジャー/プレフィックスを絞る - 最新候補を提示するときは、プレリリース風の tag と Stable 向けの差分に注意する(ユーザーのチャネル要求を優先)
3. 変更サマリ(CHANGELOG)
- CHANGELOG.md を
masterから取得する- Stable の直近リリース済み情報は、通常これで足りる
- 各バージョンのブランチを個別に取る必要はない(特別な要求が無い限り)
gh api repos/flutter/flutter/contents/CHANGELOG.md?ref=master \
--jq '.content' | base64 --decode
- 現在バージョンから対象バージョンまでの見出しを抜き出す
- 報告本文は次節のテンプレートに従い、要約で削らず翻訳して伝える
4. 報告の型
報告は assets/report.md をテンプレートとして埋めて出力する。
- テンプレートを読む(またはコピーする)
{major}.{minor}.{patch}を実バージョンに置き換える- 最新バージョン: 調査で選んだ候補(例: 指定メジャー内の最新 / Stable 最新)
- ローカルバージョン:
flutter --version(またはユーザー提示値)
## CHANGELOG以下に、ローカル版の次から最新版までを 1 バージョンずつ###見出しで並べる- 各バージョンの本文は CHANGELOG の内容を省略せず、必要なら日本語へ翻訳する(意訳で削らない。翻訳のみ)
- プレースホルダの空

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-maintenance-check-latest-version is a skill published in the GitHub repository eaglesakura/agent-skills (2 stars, last pushed 5d ago), licensed MIT. It adds 158 tokens to every session and 1,512 once invoked, about $0.0008 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.
