flutter-layered-architecture-code-search

flutter-layered-architecture-code-search is a skill for Claude Code, Codex from eaglesakura/agent-skills. It costs 196 tokens per session (1,134 once invoked), scanned A, original, MIT.

A code-finding skill for Flutter projects that use layers such as data, domain, use cases, and screens. Flutter is a toolkit for building apps with Dart, and layered architecture separates code by responsibility.

In plain words
What is it for?
Use it to find the package, screen, use case, repository, or class behind a feature, list related files, and collect TODO or FIXME notes.
Why use it?
It helps locate code in large, multi-package Flutter projects when feature names and folder structures are not obvious. It also prevents searches from stopping at documentation headings or guessed paths.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

flutter-layered-architecture-code-search 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.

What it actually says

Flutter / コード検索(Layered Architecture)

レイヤードアーキテクチャ前提のリポジトリで、指定機能・レイヤーに関する コードと関連ドキュメントの所在 を調べ、決まった型のレポートにまとめる。 ワークスペース全体の慣習は flutter-layered-architecture-workspace と併用してよい。

いつ使うか

  • 「この機能の package / 画面 / usecase はどこ?」
  • アーキテクチャレイヤー(data / domain / usecase / screen 等)単位の配置調査
  • 関連ソースのツリー一覧、TODO/FIXME、コメント上の留意点の収集

いつ使わないか

  • Markdown の見出し TOC だけで docs を読む → markdown-search
  • 文書中の path/to/file を実パスに解決するだけ → workspace-resolve-file-path
  • 新規に画面 MVVM やレイヤー設計を書く → 該当 flutter-layered-architecture-*
  • Dart の言語規約だけの修正 → flutter-coding-rules

入力の解釈

プロンプトから調査対象を特定する。例:

  • リポジトリ内の機能名(画面名・ドメイン語)
  • アーキテクチャレイヤー
  • package 名
  • 具体的なクラス / ファイル

曖昧なら、見つかった候補を列挙してから深掘りする。

調査手順

  1. ルート pubspec.yaml の workspace: からローカル package 一覧を把握する
  2. 必要なら flutter-layered-architecture-workspace / design 等でレイヤー慣習を確認する
  3. 機能名・レイヤー名から候補 package を絞る(パス断片・package 名の一致)
  4. 候補配下を探索し、ツリー・要点・TODO/FIXME・コメント留意点を集める
  5. assets/report.md のテンプレートで報告する

探索のヒント

workspace が地図になる

workspace:
  - app
  - packages/data/database
  # ローカル package が列挙されている
  • ルートの workspace: が一次の地図である
  • レイヤー/機能の命名規則(例: …/usecase/…, …/screen/…)はリポジトリごとに違う。実在パスに合わせる

1クラス1ファイル

  • 基本は 1 ファイル 1 クラスのため、ファイル名の列挙で責務を推測できる
  • レポートのソース引用は関連部分だけに絞る(出力量の最適化)

報告

  • 出力は assets/report.md に従う
  • ファイルツリーは実在パスで書く(想像のディレクトリを作らない)
  • コード引用は省略記号で前後を落とし、根拠となる断片だけ示す

ナレッジベース

DO: まず workspace、次にレイヤー推測

  • 全ディスクを無秩序に grep する前に、workspace: と命名規則で候補を絞る

DO: 発見有無を明示する

  • 見つからない場合も「無し」と書き、探した範囲を短く残す

DO NOT: 存在しないパスをツリーに足す

  • 推測配置は文章で述べ、ツリーには確認できたパスだけを載せる
Files

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.

Changes

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.
