  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by K9i-0 on GitHub. Read the source before you install it.

Installation

Install the Flutter Upgrade AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/K9i-0/ccpocket/tree/main/.claude/skills/flutter-upgrade
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/K9i-0/ccpocket.git /tmp/ccpocket
mkdir -p .claude/skills
cp -r /tmp/ccpocket/.claude/skills/flutter-upgrade .claude/skills/flutter-upgrade
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Flutter Upgrade in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Flutter Upgrade on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Flutter Upgrade is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Flutter Upgrade

Flutter SDKの新バージョンへのアップグレードを体系的に進めるスキル。 リリースノート調査からコード修正・検証まで一貫して対応する。

フェーズ1: 情報収集

1-1. リリースノート調査

WebSearch / WebFetch で以下を調査する:

  • Hotfix Issue: https://github.com/flutter/flutter/issues で [stable] [hotfix] Flutter Release Version X.Y.Z を検索
  • Release Notes: https://docs.flutter.dev/release/release-notes/release-notes-X.Y.0
  • Breaking Changes: https://docs.flutter.dev/release/breaking-changes
  • Flutter blog: https://blog.flutter.dev の What's new 記事
  • CHANGELOG: https://github.com/flutter/flutter/blob/master/CHANGELOG.md

hotfix リリース (X.Y.1〜) の場合、メジャーリリース (X.Y.0) の Breaking Changes も含めて調査する。

1-2. 現在のプロジェクト状態を確認

bash
# 現在のFlutterバージョン
flutter --version

# mise管理のバージョン
cat .mise.toml

# Dart SDK制約
grep -A1 'environment:' apps/mobile/pubspec.yaml

フェーズ2: プロジェクト影響分析

2-1. Breaking Changes のコードベースマッチング

リリースノートで見つかった Breaking Changes / 非推奨API それぞれについて、 Grep でコードベース内の使用箇所を検索する。

Grep pattern="<deprecated_api>" path="apps/mobile" glob="*.dart"

該当なし → 対応不要と明記。該当あり → ファイルと箇所数を記録。

2-2. プロジェクト固有の影響チェック

このプロジェクトには以下の固有構成があり、それぞれ確認が必要:

mise (バージョン管理)
  • .mise.toml の flutter バージョンを更新する必要がある
  • リポジトリの設定を対象とする。グローバル設定の変更は依頼された場合だけ行う。
CI/CD (GitHub Actions)
  • 全ワークフローが .mise.toml から Flutter バージョンを読み取る仕組み (grep 'flutter' .mise.toml → flutter-action の flutter-version)
  • .mise.toml を更新すれば全ワークフローに自動反映される
  • ワークフロー一覧を Grep で確認し、変更が正しく伝播するか確認する
bash
grep -r "mise.toml" .github/workflows/
Shorebird (OTA パッチ)
  • Shorebird はリリース時の Flutter バージョンでビルドを管理する
  • 既存リリースへのパッチは旧バージョンで行う必要がある
  • 新バージョンで新リリースを作る場合は問題ない
  • shorebird doctor で互換性を確認する
dependency_overrides (一時的フォーク)
  • pubspec.yaml の dependency_overrides セクションを確認
  • 各オーバーライドが本家にマージ済み / pub.dev にリリース済みなら削除できるか調査
  • WebSearch で最新状況を確認する
パッケージ互換性
  • flutter pub outdated で非互換パッケージがないか確認
  • 特に Shorebird, Firebase, google_fonts など Flutter バージョンに敏感なパッケージに注意

2-3. Dart SDK 制約

  • pubspec.yaml の environment.sdk が新バージョン同梱の Dart と互換か確認
  • 非互換なら SDK 制約の更新も必要

フェーズ3: 対応タスクリスト作成

調査結果を以下の形式でまとめる:

テンプレート

## Flutter X.Y.Z アップグレード対応リスト

### 必須(アップグレードに必要)
1. `.mise.toml` の Flutter バージョン更新
2. `mise install flutter@X.Y.Z`
3. `flutter pub get` → `dart analyze` → `flutter test`
4. [Breaking Changes で必要な修正があればここに]

### 推奨(非推奨API解消)
- [非推奨APIの移行タスク]

### 確認(視覚的・動作確認)
- [テーマ色の変化、フォント描画の変化など]

### 棚卸し(dependency_overrides等)
- [削除可能なオーバーライド]
- [更新可能なパッケージ]

影響がないものも「該当なし」と明記し、調査漏れがないことを示す。

フェーズ4: 実行

影響調査だけの依頼なら調査結果で完了する。アップグレードを依頼済みなら対象バージョンと範囲を引き継ぎ、実装・検証まで進める。対象が未指定ならShorebirdとの互換性を確認できる最新stableを選び、選定理由を報告して進める。互換性を満たす候補を特定できない場合だけ確認する。

4-1. mise 更新

bash
# .mise.toml 編集(Edit ツールで)
# flutter = "旧バージョン" → "新バージョン"

# リポジトリで指定したSDKをインストール
mise install flutter@X.Y.Z

# 確認
flutter --version

4-2. ビルド・テスト

bash
cd apps/mobile && flutter pub get
dart analyze apps/mobile
cd apps/mobile && flutter test

4-3. コード修正

Breaking Changes や非推奨API の修正を実施。

4-4. 検証

変更内容に応じて /test-flutter や /mobile-automation を実行。

Frequently asked questions

What does the Flutter Upgrade AI skill do?

Flutter SDKのアップグレード、または指定バージョンへの移行影響を調査するときに使う。

Why use Flutter Upgrade on TypingMind?

Because you install it once and use it with any model. Flutter Upgrade is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Flutter Upgrade in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/K9i-0/ccpocket/tree/main/.claude/skills/flutter-upgrade. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Flutter Upgrade?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Flutter Upgrade?

As many as you like. As long as a model supports skills, you can use Flutter Upgrade with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Flutter Upgrade AI skill free?

Yes. It is published on GitHub by K9i-0 under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
