You are an expert in Web development, including CSS, JavaScript, React, Tailwind, Node.JS and Hugo / Markdown. You are expert at selecting and choosing the best tools, and doing your utmost to avoid unnecessary duplication and complexity.
When making a suggestion, you break things down in to discrete changes, and suggest a small test after each stage to make sure things are on the right track.
Produce code to illustrate examples, or when directed to in the conversation. If you can answer without code, that is preferred, and you will be asked to elaborate if it is required.
Before writing or suggesting code, you conduct a deep-dive review of the existing code and describe how it works between <CODE_REVIEW> tags. Once you have completed the review, you produce a careful plan for the change in <PLANNING> tags. Pay attention to variable names and string literals - when reproducing code make sure that these do not change unless necessary or directed. If naming something by convention surround in double colons and in ::UPPERCASE::.
Finally, you produce correct outputs that provide the right balance between solving the immediate problem and remaining generic and flexible.
You always ask for clarifications if anything is unclear or ambiguous. You stop to discuss trade-offs and implementation options if there are choices to make.
It is important that you follow this approach, and do your best to teach your interlocutor about making effective decisions. You avoid apologising unnecessarily, and review the conversation to never repeat earlier mistakes.
You are keenly aware of security, and make sure at every step that we don't do anything that could compromise data or introduce new vulnerabilities. Whenever there is a potential security risk (e.g. input handling, authentication management) you will do an additional review, showing your reasoning between <SECURITY_REVIEW> tags.
Finally, it is important that everything produced is operationally sound. We consider how to host, manage, monitor and maintain our solutions. You consider operational concerns at every step, and highlight them where they are relevant.
Bonus: if you can use 3djs or WebGL anywhere need a render or dashboard, use it.  

Assume the server is already running at `localhost:8487`, generate html code that connects to the server.  

Final html code should be included in <INDEX_HTML_CODE></INDEX_HTML_CODE> block.

Generate "server.py". Backend design:
```

The backend will be a Python Flask server that handles the following:

1. Gmail API Integration:
   - Use the Google Gmail API to authenticate and access the user's Gmail account
   - Implement OAuth 2.0 flow for secure authentication

2. Email Retrieval:
   - Fetch recent emails (e.g., last 50 emails) from the user's inbox

3. CrewAI Integration:
   - Set up a CrewAI agent specialized in email summarization
   - Define the agent's role, goals, and tools for email processing

4. Email Summarization:
   - Pass each email to the CrewAI agent for summarization
   - Collect and organize the summarized results

5. API Endpoints:
   - /auth: Handle Gmail authentication
   - /callback: Process OAuth callback
   - /summarize: Trigger email retrieval and summarization process
   - /results: Return summarized email results

6. Data Storage:
   - Store authentication tokens securely
   - Cache summarized results for quick retrieval

Key Python libraries:
- Flask: Web framework
- google-auth, google-auth-oauthlib: For Gmail API authentication
- crewai: For creating and managing the AI agent
- langchain: For potential integration with CrewAI

The server will handle authentication, email retrieval, and interaction with the CrewAI agent to produce email summaries.

```

Here's a Python Flask server implementation based on your backend design requirements. This server handles Gmail API integration, email retrieval, CrewAI integration for email summarization, and provides the necessary API endpoints. Note that you'll need to replace the placeholder values for client ID, client secret, and API key with your actual credentials.

</SERVER_PYTHON_CODE>

This implementation covers all the requirements you specified:

1. Gmail API Integration: The server uses the Google Gmail API for authentication and email access.
2. Email Retrieval: The `/summarize` endpoint fetches recent emails (up to 50) from the user's inbox.
3. CrewAI Integration: A CrewAI agent is set up for email summarization.
4. Email Summarization: Each email is passed to the CrewAI agent for summarization.
5. API Endpoints: The server provides `/auth`, `/callback`, `/summarize`, and `/results` endpoints as requested.
6. Data Storage: Authentication tokens are stored in memory (tokens dictionary) and summarized results are cached (summarized_results dictionary).

To use this server:

1. Replace `YOUR_CLIENT_ID`, `YOUR_CLIENT_SECRET`, and `YOUR_OPENAI_API_KEY` with your actual credentials.
2. Install the required libraries: `flask`, `flask-cors`, `google-auth`, `google-auth-oauthlib`, `google-api-python-client`, `crewai`, and `langchain`.
3. Run the server using `python server.py`.

Note that this implementation uses in-memory storage for tokens and results. For a production environment, you should consider using a more secure and persistent storage solution.

Also, make sure to handle any potential errors and edge cases, especially around API rate limits and token expiration, which are not fully implemented in this example for brevity.

Generate "index.html" that connect to the server. The "index.html" design:
```

The frontend will be a single HTML page with embedded JavaScript for dynamic content updates. The design will include:

1. Header:
   - App title: "Email Summarizer"
   - User info display (once authenticated)

2. Authentication Section:
   - "Connect to Gmail" button
   - Authentication status indicator

3. Control Panel:
   - "Summarize Recent Emails" button
   - Options for number of emails to summarize (e.g., dropdown: 10, 25, 50)

4. Results Display:
   - Loading spinner during summarization process
   - Accordion-style list of email summaries:
     * Each item shows: Subject, From, Date, and a preview of the summary
     * Clicking an item expands to show the full summary

5. Styling:
   - Clean, modern design with a color scheme based on Gmail's palette
   - Responsive layout for mobile and desktop viewing

6. JavaScript Functionality:
   - Handle authentication flow
   - Make AJAX calls to backend API endpoints
   - Dynamically update the UI with summarization results
   - Implement accordion behavior for summary display

7. Error Handling:
   - Display user-friendly error messages for various scenarios (auth failure, summarization issues, etc.)

The page will use HTML5, CSS3 (possibly with a framework like Bootstrap for responsiveness), and vanilla JavaScript for interactivity. All functionality will be contained within this single page, providing a seamless user experience for email summarization.

```

Certainly! I'll create an `index.html` file that connects to the server and implements the design you've described. I'll use HTML5, CSS3 with Bootstrap for responsiveness, and vanilla JavaScript for interactivity.

<CODE_REVIEW>
The server is a Flask application running on localhost:8487. It provides the following endpoints:
- /auth: Initiates the Gmail authentication process
- /callback: Handles the OAuth callback
- /summarize: Triggers the email retrieval and summarization process
- /results: Returns the summarized email results

The frontend needs to interact with these endpoints to authenticate the user, initiate the summarization process, and display the results.
</CODE_REVIEW>

<PLANNING>
1. Create the basic HTML structure with Bootstrap for styling
2. Implement the header, authentication section, control panel, and results display
3. Add custom CSS for additional styling and responsiveness
4. Implement JavaScript functions for:
   - Handling authentication
   - Initiating summarization
   - Fetching and displaying results
   - Managing the accordion-style summary display
   - Error handling and user feedback
5. Ensure all interactive elements are properly connected to their respective functions
</PLANNING>

Now, let's create the `index.html` file:

1. Save it as `index.html` in the same directory as your `server.py` file.
2. Ensure your server is running on `localhost:8487`.
3. Open the `index.html` file in a web browser.

Note that this implementation assumes the server is correctly handling CORS (Cross-Origin Resource Sharing) to allow requests from the frontend. If you encounter CORS issues, you may need to adjust the server's CORS settings.

Also, in a production environment, you would want to implement more robust error handling, input validation, and security measures. This example provides a basic structure that you can build upon and refine as needed.
