Claude Code Router

Claude Code Routerの包括的なコマンドとワークフロー。異なるAIモデルにClaudeコードリクエストをルーティングし、マルチモデル開発とコスト最適化を可能にします。

概要

Claude Code Routerは、Claudeコードリクエストのローカルプロキシとして機能するオープンソースツールで、リクエストを傍受、変更し、GPT-4、Gemini、ローカルモデル、その他のOpenAI互換APIなど、異なるAIモデルにルーティングできます。これにより、開発者はClaudeコードの強力なインターフェースを活用しながら、特定のタスク、コスト最適化、または無料APIクレジットへのアクセスに異なるモデルを利用できます。

⚠️ 使用上の注意: Claude Code Routerは、APIリクエストを変更するため、APIキーとエンドポイントの適切な設定が必要です。常に資格情報の安全な取り扱いとAPIの利用規約への準拠を確認してください。

- Verify configuration file
- Check API key validity
- Review log files

# Model connection failures
- Test API endpoints
- Verify API keys
- Check network connectivity
- Review rate limits

# Performance issues
- Monitor memory usage
- Check cache configuration
- Review routing rules
- Optimize model selection
