In plain words

Why use it?
They keep the agent's conversation, code changes, and tests consistent with that repository's conventions.

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/claude-code-server's own configuration. It tells Claude Code how to work on claude-code-server 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 claude-code-server 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

claude-code-server CLAUDE.md scanned grade A with 1 finding 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

CLAUDE.md

このファイルは、Claude Code (claude.ai/code) がこのリポジトリでコードを作業する際のガイダンスを提供します。

ルール

  • 日本語で会話してください。
  • 新しい施策を試す前に、思考プロセスをユーザーに説明してください。

テストコードのルール

テストコードは以下のルールに従って作成してください:

1. テストメソッド命名規則

テストメソッド名は以下の形式で命名してください:

test_{対象機能}_{テスト条件}_と_期待結果であること

例:

def test_models_endpoint_GETリクエストを送信した場合_claude_sonnet_4だけが返されること(self, server_process):
def test_chat_completion_正常なチャットリクエストを送信した場合_回答が得られること(self, server_process, client):
def test_chat_completion_チャットリクエストで無効なAPIキーでリクエストを送信した場合_例外が発生すること(self, server_process):
2. AAAパターンの実装

すべてのテストメソッドは以下の3つのセクションに明確に分割してください:

def test_example_テスト条件_期待結果であること(self, fixtures):
    #------------------------------
    # 準備 (Arrange)
    #------------------------------
    # テストデータの設定、モックの準備など
    
    #------------------------------
    # 実行 (Act)
    #------------------------------
    # テスト対象の機能を実行
    
    #------------------------------
    # 検証 (Assert)
    #------------------------------
    # 結果の検証とアサーション
3. テストメソッドの構造化
  • 準備 (Arrange): テストに必要なデータ、オブジェクト、モックを設定
  • 実行 (Act): テスト対象の機能を実行(1つの操作に集中)
  • 検証 (Assert): 期待される結果と実際の結果を比較・検証
4. テストケースの焦点化
  • 各テストメソッドは1つの具体的なシナリオに集中する
  • 複雑な並行処理や複数の条件を組み合わせたテストは避ける
  • 基本的な動作確認を重視し、エッジケースは別のテストで扱う
5. BDDスタイルの採用

テスト名と内容は「〜の場合、〜であること」という形式で、ビジネス要件を明確に表現してください。

プロジェクト概要

これは、claude-code CLIをラップしてClaude AIの機能を標準APIインターフェース経由で提供する、OpenAI API互換サーバーです。LiteLLMをプロキシサーバーとして使用してOpenAI互換のリクエストを処理し、claude-code CLIに転送します。

アーキテクチャ

システムは2つの主要コンポーネントで構成されています:

  1. LiteLLM Proxy (litellm_config.yaml): ポート4000でOpenAI互換APIリクエストを処理
  2. Custom Provider (claude_code_server/provider.py): claude-code CLIコマンドを実行するCustomLLMクラス

フロー: OpenAI APIリクエスト → LiteLLM → ClaudeCodeProvider → claude-code CLI → レスポンス

主要な実装詳細

  • CustomLLM継承: ClaudeCodeProviderはLiteLLMのCustomLLM基底クラスを拡張
  • 非同期サポート: completion()とacompletion()メソッドの両方を実装
  • プロバイダー登録: litellm_config.yamlのcustom_provider_mapで登録
  • モデルマッピング: claude-sonnet-4 → claude-code-server/claude-code

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.
