local-RAG-backend: Instructions file for Claude Code

CLAUDE.md

local-RAG-backend CLAUDE.md is an instructions file for Claude Code from suwa-sh/local-RAG-backend. It costs 5,262 tokens per session, scanned A, original, MIT.

A repository instruction file for Claude Code, written for the suwa-sh/local-RAG-backend project. It sets Japanese communication, planning, testing, file-handling, and software design rules.

In plain words
What is it for?
Use it to guide changes in this repository, including design diagrams, test-first development, temporary files, and communication with the user.
Why use it?
It keeps the coding agent's work consistent with the project's chosen process and structure. It also records work context so progress can survive between tasks.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is suwa-sh/local-RAG-backend's own configuration. It tells Claude Code how to work on local-RAG-backend itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything local-RAG-backend configures →

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

local-RAG-backend CLAUDE.md 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 8d 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

■プロジェクトコンセプト

@README.md を参照してください。

■コミュニケーションルール

  • 日本語で会話してください
  • 進め方を計画してユーザーと認識を合わせてから、実装を進めてください
  • 現在の作業状況は @tmp/active_context.md に記録してください
  • ユーザーからプロンプトの追加情報で @tmp/current_prompt.md が渡されることがあります
  • 動作確認などに必要な一時的なファイルは tmp/ ディレクトリ配下に出力してください

重要

  • ファイルの文字コードはUTF-8を使用してください
  • bugfixでユーザーとやり取りする内容はサンプルです。 決してハードコーディングしないでください
  • ユーザーに提示する前に可能な限りの動作確認、テストを実施してください

■開発ルール

進め方

  • 設計 -> ユーザーと仕様を認識合わせ -> TDDで実装を進める

設計方針

  • C4モデルで構造を整理
  • USMでユースケースを整理
  • ユースケースごとにドメインモデリング
    • ドメインモデル図: 具体的な値をオブジェクト図で表現
    • クラス図: ドメインモデルのクラス構造を表現
  • DDDに従う
  • 図解にはmermaidを利用
    • C4モデルは、mermaid graph記法
      • 図解に説明は含めないでください
      • 説明は markdown tableで、要素名、説明のレイアウトで記載してください

レイヤー構造と依存関係

ユースケース層 → アダプター層 → 外部ライブラリ
     ↓              ↓              ↓
  直接利用        直接実装      mockでテスト
  • プレゼンテーション層: src/main/ (CLIエントリーポイント)
  • ユースケース層: src/usecase/ (アダプター層を直接利用)
  • ドメイン層: src/domain/ (ビジネスロジック)
  • アダプター層: src/adapter/ (外部ライブラリとの実装)

重要: リポジトリ層のインターフェースは使用せず、アダプター層を直接利用する

TODO(将来対応): 本来はリポジトリ層(インターフェース)経由にしたい。 現状はユースケース層がアダプター層を直接利用しているが、ドメイン層に リポジトリインターフェースを定義し、アダプター層をその実装として 差し替える構成へ移行する。移行時は上記の「重要」記述とテスト戦略の 該当箇所も更新すること。

テスト戦略

アダプター層のテスト
  • 対象: 外部ライブラリとの連携ロジック
  • Mock対象: 外部ライブラリのみ(Graphiti、Unstructured.io等)
  • : GraphitiEpisodeRepository, UnstructuredDocumentParser
ユースケース層のテスト
  • 対象: ビジネスロジック全体
  • Mock対象: 外部ライブラリのみ
  • 利用: アダプター層を直接利用した結合テスト
  • メリット: より実際に近いテストが可能
ドメイン層のテスト
  • 対象: ドメインロジック
  • Mock対象: なし(純粋な単体テスト)

開発支援

  • rye: パッケージ管理と仮想環境の構築
  • pytest: テストフレームワーク
  • qlty: コード品質チェックツール(linter, formatter, static analyzer)

実装完了時の確認

実装タスク完了時は 必ず make check を実行してからユーザーに提示してください。

make check

これによって以下が実行されます:

  1. make fmt - コードフォーマット
  2. make lint - コード品質チェック
  3. make test - テスト実行

すべてが正常に完了することを確認してから、実装完了を報告してください。

決定した内容は @DEVELOPER.md に記録してください

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.
