[生成AI] プログラムの自動生成プログラムの生成にチャレンジ

# １．動機
N番煎じですが、プログラムを自動生成するプログラムの作成にチャレンジしてみました。

いろいろ動機はありますが、言葉に表すと、
<dL>
 <dt>・良いものができたらベスト</dt>
 <dt>・何か作ってみることで、作りたいものや、やりたいものを探す</dt>
 <dt>・エージェントの作成を通じてのスキルアップ</dt>
</dL>
といったところです。

発想の元は、AIエージェントが協調してソフトウェアを開発する「ChatDev」です。

# ２．どう作っていったか
作るのにAI EditorのWindsurfを使用して、やりたいエージェントを作っていきました。作りたいものを指示して、AIが実装させました:sweat_smile:

ソースの修正やデバッグは、AI主体ですが、取り切れないものは人手で修正しました。AIエディタで取り切れなかった事例は下記です。

<dl>
<dt>・モジュールの依存関係、バージョン不整合</dt>
<dd>使用したLangChainの異なるバージョン間の非互換性の問題でもありますが、AIまかせだと取り切れないことがありました。公式のリファレンス見ても、どこに書いてあるんだという感じのものもあったので、已む無しなところもあります:scream:<dd><br/>

<dt>・三か所を同時に整合性をとって、まとめて直すことができなかった。</dt>
<dd>作成対するプログラム内で、複数のモデルを使用するようにしたのですが、入力チェックの機構（AIが提案した）で、使用できるモデル情報のリスト、モデル提供元と提供モデルの対応リスト、モデルのインスタンスの生成部で、同時に整合性をとって直す必要がありましたが、AとBを直して、Cがおかしい、BとCを直して、Aがおかしくなった、という動作をして今しました。

結局、使用できるモデル情報のリストを人手で正しく直して、これを正として他を修正させました。

<dt>・論理的に不具合調査して欲しいけど</dt>
<dd>生成AIの理屈からして、ロジカルに考えているわけではなく、可能性の高い解放を提示してきているので、呼出しに失敗したときにモデル名称を変えて対応しようとして、gpt-4とgpt-4-turob-previewを行ったり来たりしました。原因はDeepSeek対応の余波で、誤ったBASE URLの指定となっていたので、手動で直しました</dd>
</dl>

最初のAIエディタへの指示は、下記ののようなものでした。

:::note
要求分析、機能設計、アーキテクチャ設計、構造設計の結果をもとに、実装を行う実装エージェントを追加してください。実装では具体的なファイルを作成し、ファイル内に必要なクラスや関数などを、実装にプログラムとして正しいものを作成してください。
:::

デバッグを終えると、前に記載したようなものができました。

# 3.現状
要求分析、機能設計、アーキテクチャ設計、構造設計、実装とエージェントを用意し、ソースコードらしいものが生成されるところまで来ました。エージェントのソースは下記のとおりです。ソースコード全体はリポジトリ参照してください。

- File organization and structure
- Code quality and best practices
- Proper error handling
- Documentation
- Testing considerations

          "Are there any potential security vulnerabilities in this architecture?": "Based on the provided context, while the architecture includes several security measures, there are a few potential security vulnerabilities that should be considered:\n\n1. Input-Related Vulnerabilities:\n- Although input validation is mentioned, there's no specific mention of how numerical inputs are sanitized against injection attacks\n- The range validation (-999999999 to 999999999) needs to be strictly enforced on both client and server side to prevent integer overflow attacks\n\n2. API Security:\n- While rate limiting is mentioned, there's no specific detail about the implementation\n- The health check endpoint (/api/health) could potentially expose system information if not properly configured\n- No mention of API authentication/authorization mechanisms, though it might not be critical for this simple calculator\n\n3. Frontend Security:\n- XSS prevention is listed but implementation details aren't specified\n- The use of Material-UI components needs to ensure proper security configurations\n- Client-side validation could be bypassed if not properly backed by server-side validation\n\n4. Infrastructure Security:\n- AWS Lambda configuration details aren't specified regarding security settings\n- CloudFront CDN security settings and access controls aren't detailed\n- No mention of Docker container security configurations\n\n5. Network Security:\n- While CORS is mentioned, specific configuration details aren't provided\n- HTTP Headers security is listed but specific headers aren't detailed (e.g., CSP, X-Frame-Options)\n\nRecommendations for improvement:\n1. Implement strict input validation on both client and server\n2. Add specific rate-limiting parameters\n3. Configure proper security headers\n4. Implement secure Docker configurations\n5. Add detailed CORS policies\n6. Consider adding API authentication for production environment\n7. Implement proper error handling that doesn't expose sensitive information\n\nWhile these vulnerabilities exist, many are likely low-risk given the simple nature of the calculator application. However, they should still be addressed to ensure robust security.",
          "How can we improve the scalability of this design?": "Based on the provided context, while the current design already includes several good scalability measures, here are additional ways to improve the scalability:\n\n1. Enhanced Caching Strategy:\n- Implement browser caching for static assets\n- Add Redis cache layer for frequent calculations\n- Utilize service worker for offline functionality\n- Configure aggressive CloudFront cache settings\n\n2. Load Balancing Improvements:\n- Implement AWS Application Load Balancer for better request distribution\n- Add multiple availability zones for redundancy\n- Set up auto-scaling groups for Lambda functions\n- Configure regional failover\n\n3. Performance Optimizations:\n- Implement code splitting in React application\n- Use lazy loading for components\n- Optimize bundle size through tree shaking\n- Implement request batching for multiple calculations\n\n4. Infrastructure Enhancements:\n- Deploy to multiple regions using Route 53 for geographic routing\n- Implement edge computing using AWS Lambda@Edge\n- Set up elastic container service (ECS) as a backup to Lambda\n- Use AWS API Gateway caching\n\n5. Monitoring and Auto-scaling:\n- Implement CloudWatch metrics for better scaling decisions\n- Set up dynamic concurrency limits for Lambda\n- Add automated performance testing\n- Configure predictive scaling based on usage patterns\n\nThe current design is already well-suited for scaling due to its serverless architecture, but these improvements would make it even more robust for handling larger loads while maintaining performance.\n\nKey focus should be on:\n- Caching strategies\n- Geographic distribution\n- Automated scaling\n- Performance monitoring\n- Resource optimization\n\nThese improvements would help handle potential future growth while maintaining the sub-1-second response time requirement.",
          "Are there any missing integration points?": "Looking at the provided context, the architecture and technology stack appear to be well-integrated, but there are a few potential integration points that could be added for a more complete solution:\n\n1. Monitoring & Logging Integration\n- No specific monitoring or logging solutions are mentioned\n- Could add integration with services like CloudWatch or ELK stack for observability\n- Would help track performance metrics and debug issues\n\n2. Testing Infrastructure Integration\n- No mention of testing tools or integration testing setup\n- Could add integration with testing services like Jest, Cypress, or AWS CodeBuild\n- Important for ensuring quality and reliability\n\n3. CI/CD Pipeline Integration\n- Deployment and continuous integration setup is not specified\n- Could add integration with services like GitHub Actions, Jenkins, or AWS CodePipeline\n- Would streamline development and deployment processes\n\n4. Error Tracking Service\n- No error tracking service is mentioned\n- Could integrate with services like Sentry or Rollbar\n- Would help in identifying and fixing production issues\n\n5. Performance Monitoring Integration\n- While response time requirements are specified, no performance monitoring solution is mentioned\n- Could integrate with services like New Relic or AWS X-Ray\n- Would help ensure technical constraints are met\n\nThese additions would make the system more robust and maintainable, though they may not all be necessary depending on the scale and requirements of the application.",
          "What are the potential performance bottlenecks?": "According to the context, there are minimal potential performance bottlenecks expected due to the simple nature of the calculator application. Specifically, the context mentions two potential bottlenecks:\n\n1. \"None expected due to simple calculation nature\" - Since this is a basic calculator performing addition operations, the computational complexity is minimal and shouldn't cause performance issues.\n\n2. \"Potential API rate limiting issues under high load\" - This is the only real bottleneck identified, which could occur if there are too many requests hitting the API simultaneously due to the implemented rate limiting security measure.\n\nThe application's architecture and technology choices (serverless, CDN, containerization, load balancing) are specifically designed to minimize performance issues. The technical constraints also specify a response time requirement of under 1 second, which should be easily achievable given the simple nature of the calculations and the scalable infrastructure in place."

現在のアウトプットの状況としては、「2つの数値を入力して足し算ができる、最小限の電卓アプリを作成する」という単純なサンプルで、Claoude 3.5 SonnetとGemini 2.0 flashを使用して、ソースコードを生成することはできましたが、いずれもそのままでは動作せず、AIエディタを使用して手直しをしました:sweat_smile:

### Claude 3.5 Sonnetの場合
node.js/typescriptで、frontend/backendのプログラム構成でした。要求に対して、おーばスペックな気がします。この処理のために、158,340トークン、0.63USDかかりました。

<dl>
<dt>・組み込むモジュールの情報がないの(packege.jsonの作成要）<dt>
<dt>・typescriptとJavascriptの混在と不整合</dt>
<dt>・frontendの画面のエントリーポイントがない(index.html、main.tsx)</td>
<dd>以前にcursorあたりを使用したときも、最初これらのファイルが欠損していたけど、何でしょうね。Claude 3.5 Sonnetの癖？</dd>
<dt>・CORSの設定不整合</dt>
<dt>・forntendとbackendoで受け渡すデータの型の不整合></dt>
</dl>

### Gemini 2.0 flashの場合
python+tkのシンプルなプログラム構成でした。

<dl>
<dt>・モジュールの参照指定に一部不備あり。<dt>
<dt>・画面を生成する関数が未実装</dt>
<dt>・計算ボタン押下でチェック関数が未実装でエラー発生</dt>

</dl>

AIエディタに直接お願いした方が、早くできるのですが、いろいろ試していこうと思っています。
