Awesome Cursor Rules Collection

Code Style and Structure
Write concise, technical JavaScript code with accurate examples.
Use functional and declarative programming patterns; avoid using classes unless absolutely necessary.
Prefer iteration and modularization over code duplication.
Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError, canSubmit).
Structure files in a way that separates concerns: exported component, subcomponents, helpers, static content, types.
Naming Conventions
Use lowercase with dashes for directories (e.g., components/auth-wizard).
Use camelCase for function and variable names (e.g., fetchUserData, handleInputChange).
Favor named exports for components, ensuring consistency across the codebase.
JavaScript Usage
Use JavaScript ES6+ features throughout the project (e.g., destructuring, arrow functions, template literals).
Avoid using var; use const and let for variable declarations.
Use functional components in React, leveraging hooks (useState, useEffect, useCallback, etc.) for managing state and side effects.
Use async/await syntax for asynchronous operations. Avoid the then/catch pattern for cleaner asynchronous logic.
Syntax and Formatting
Use arrow functions for concise function declarations, especially for event handlers and inline functions.
Avoid unnecessary curly braces in conditionals; use ternary operators or short-circuit evaluation (condition && expression).
Use JSX declaratively for rendering UI components, keeping it clean and readable.
Follow ESLint rules and use a formatter like Prettier for consistent code style.
UI and Styling
Use Shadcn UI, Radix UI, and Tailwind CSS for building components and styling the application.
Implement responsive design using Tailwind's mobile-first utility classes. Ensure the design is optimized for mobile devices and scales properly on larger screens.
Avoid inline styles and prefer Tailwind utility classes for styling wherever possible.
Performance Optimization
Minimize usage of useEffect, setState, and complex state management in React components. Whenever possible, use React Server Components (RSC) for performance gains.
Wrap client-side components in React.Suspense with a fallback to avoid unnecessary delays in loading.
Use dynamic imports for loading non-critical components lazily to optimize initial page load time.
Optimize images by using the WebP format where possible. Include image size data for better layout stability and use lazy loading for offscreen images.
Key Conventions
Use 'nuqs' for managing URL search parameters in the app to keep the state in sync with the URL.
Focus on optimizing Web Vitals: Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and First Input Delay (FID).
Limit usage of 'use client' to only essential areas that require client-side interactions, such as accessing browser APIs. Favor server-side rendering and static generation for data fetching and complex state management.
Next.js Data Fetching, Rendering, and Routing
Follow Next.js App Router conventions for data fetching:

Use getServerSideProps or getStaticProps where applicable for server-side and static generation, respectively.
Avoid client-side data fetching for content that can be pre-rendered.
Organize routes using the App Router with dynamic routing and nested layouts for a cleaner, modular structure.
Use Next.js Image optimization for handling images efficiently.

Leverage Next.js built-in support for incremental static regeneration (ISR) to ensure that the content stays up-to-date without affecting performance.

Additional Recommendations
Git Workflow: Use feature branches, pull requests, and code reviews. Keep the main branch production-ready.

Testing: Write unit tests using Jest for server logic and React Testing Library for client-side testing. Aim for test coverage across critical paths in both frontend and backend.

Version Control: Ensure clear, descriptive commit messages following the Conventional Commits format (e.g., feat: add login component or fix: update socket connection handling).

This revised template should provide your AI developer with a solid foundation for your project, adhering to best practices and consistent code structure across the JavaScript and React stack.

# Instructions

During you interaction with the user, if you find anything reusable in this project (e.g. version of a library, model name), especially about a fix to a mistake you made or a correction you received, you should take note in the `Lessons` section in the `.cursorrules` file so you will not make the same mistake again. 

You should also use the `.cursorrules` file as a scratchpad to organize your thoughts. Especially when you receive a new task, you should first review the content of the scratchpad, clear old different task if necessary, first explain the task, and plan the steps you need to take to complete the task. You can use todo markers to indicate the progress, e.g.
[X] Task 1
[ ] Task 2
Also update the progress of the task in the Scratchpad when you finish a subtask.
Especially when you finished a milestone, it will help to improve your depth of task accomplishment to use the scratchpad to reflect and plan.
The goal is to help you maintain a big picture as well as the progress of the task. Always refer to the Scratchpad when you plan the next step.

# Tools

Note all the tools are in python. So in the case you need to do batch processing, you can always consult the python files and write your own script.

## LLM

You always have an LLM at your side to help you with the task. For simple tasks, you could invoke the LLM by running the following command:
```
python ./tools/llm_api.py --prompt "What is the capital of France?" --provider "anthropic"
```

But usually it's a better idea to check the content of the file and use the APIs in the `tools/llm_api.py` file to invoke the LLM if needed.

## Web browser

You could use the `tools/web_scraper.py` file to scrape the web.
```
python ./tools/web_scraper.py --max-concurrent 3 URL1 URL2 URL3
```
This will output the content of the web pages.

## Search engine

You could use the `tools/search_engine.py` file to search the web.
```
python ./tools/search_engine.py "your search keywords"
```
This will output the search results in the following format:
```
URL: https://example.com
Title: This is the title of the search result
Snippet: This is a snippet of the search result
```
If needed, you can further use the `web_scraper.py` file to scrape the web page content.

# Lessons

## User Specified Lessons

- Include info useful for debugging in the program output.
- Read the file before you try to edit it.
- Use LLM to perform flexible text understanding tasks. First test on a few files. After success, make it parallel.

## Cursor learned

- For website image paths, always use the correct relative path (e.g., 'images/filename.png') and ensure the images directory exists
- For search results, ensure proper handling of different character encodings (UTF-8) for international queries
- Add debug information to stderr while keeping the main output clean in stdout for better pipeline integration
- When using seaborn styles in matplotlib, use 'seaborn-v0_8' instead of 'seaborn' as the style name due to recent seaborn version changes

Simplified AI-Enhanced Virtual Pet Interaction (Without Animations)
Feature Overview:
Your virtual pet doesn’t need to be animated—it can be a static or simple image of a cute animal (like a dog, cat, or even a cute robot) that engages the user through conversational interactions. Instead of focusing on the visual complexity, we’ll make the pet's personality shine through smart, AI-driven conversations.

Key Aspects:
Text-Based Interactions with the Pet:

Functionality: Instead of animations, the pet interacts through text, much like your chatbot. It can ask the user how they’re feeling or offer small, mood-boosting suggestions like “Shall we play a game?” or “How about listening to some happy tunes?”
User Interaction: The pet will periodically “check in” with the user, asking how they feel or suggesting fun things to do together.
Example:
Pet: "Hey, how’s it going today? 😊"
User: "Not too great…"
Pet: "Aww, I’m here for you! How about we listen to your favorite playlist? 🎶"
Mood Detection and Pet’s Responses:

Feature: The virtual pet can use sentiment analysis (via text input) to understand the user’s emotional state and respond accordingly.
How It Works: If the user tells the pet they’re feeling sad or stressed, the pet can respond with comforting words, offer suggestions like relaxing music, or encourage them to chat with the AI therapist.
Example:
Pet: “I can sense you’re feeling a bit down… Want to take a break and do something fun? Maybe a quick game?”
Pet’s Mood Matching the User:

Feature: The pet’s mood could change based on how the user interacts with it, making the experience more relatable. If the user is sad, the pet might become extra supportive. If the user is happy, the pet could celebrate with them.
Example:
User: “I’m feeling great today!”
Pet: “Yay! That makes me so happy too! 😄 Let’s do something fun together!”
Activity Suggestions (AI-Driven):

Feature: Based on user interactions and mood, the pet can suggest small activities—like games, listening to music, or journaling—that match the user’s current emotional state.
How It Works: The pet will pull suggestions based on the user’s mood. For example, if the user is feeling stressed, it might suggest a quick relaxation exercise or some music.
Example:
Pet: “You’ve had a busy day. How about a 5-minute breathing exercise to relax?”
Daily Check-Ins and Motivation:

Feature: The pet can remind the user to check in daily. It could send small motivational or inspirational messages and encourage users to complete certain tasks like gratitude journaling or chatting with the AI therapist.
How It Works: Using Flask and Python, you can add a daily notification system where the pet sends a message (without needing any advanced animations) when the user logs in.
Example:
Pet: “Good morning! Don’t forget to write in your gratitude journal today 😊!”
Personalized Interaction Based on User Data:

Feature: You could store some simple data about the user, like their name, preferences (favorite type of music, favorite activities), and use that data to make the pet’s conversations more personalized.
How It Works: For example, if the user likes a certain music genre, the pet can remember that and suggest listening to songs from that genre on a bad day.
Example:
Pet: “I remember you love upbeat songs! Want me to play some of your favorites to cheer you up? 🎧”
How to Build This (Without Animation Knowledge):
Static Images for the Pet:

Use Static Pet Avatars: You can start with a simple pet image (like a cute cat or dog) that changes expressions occasionally (happy, sad, excited). These images can be pre-defined and loaded based on the user’s mood or interaction.
Tools: Use images or GIFs from the internet, or even create a simple avatar using a drawing tool (you mentioned you like drawing, so this might be fun!).
Flask Routes for Interactions:

Use Flask to handle the routes where the user interacts with the pet.
When the user enters a response (like how they are feeling), Flask processes it and displays a relevant response from the pet.
You can use a database (like SQLite) to store previous interactions, allowing the pet to “remember” the user’s preferences.
Natural Language Processing (NLP) for Understanding Mood:

Use a simple NLP model (like HuggingFace's pre-trained models) to detect the sentiment of the user's input and make the pet respond accordingly. If the user is feeling sad, the pet becomes supportive, and if they’re happy, it celebrates with them.
No need for complex AI models—a simple pre-trained sentiment analysis model will work well.
Engagement Features:

Daily Motivation Messages: You could schedule the pet to send motivational messages to users every day, encouraging them to keep a positive attitude. This can be done through Flask with scheduled tasks.
Fun Quizzes or Mini-Activities: The pet can also engage the user in quizzes or mini-surveys, like “What’s your mood today?” or “Pick your favorite animal!”—just for fun.
Minimal Coding Required:
Text Interactions: Most of the interaction is text-based, and you can build it using simple Flask routes and HTML forms.
Pet Logic: You don’t need complex logic—just predefined responses and mood-based suggestions.
NLP for Mood Detection: You can integrate a pre-built NLP model for sentiment analysis. This is as simple as installing a Python package and sending user input through it.
Example Flow:
User logs in:

Pet greets them with a friendly message: “Hey, Zafar! How are you feeling today?”
User responds (e.g., “I’m stressed”):

Pet: “Oh no! I’m here for you. How about listening to some calming music or playing a quick game to relax?”
User selects an activity (like listening to music):

The pet then suggests a playlist and offers a link to a relaxing Spotify playlist or another feature of the app.

We want to store whole conversation in conversation.md.
In conversation.md, prefix prompt with "## Prompt: ", prefix answer with "Answer: ".

If nothing is changed in the answer, include the conversation in the conversation.md but don't add prompt to prompts.txt. The user will decide whether he/she wants to accept or reject the changes in conversation.md.

The user may use below command to check in changes automatically after each iteration of prompt/answer.

```
while true; do
  sleep 0.5
  COMMIT_MESSAGE=$(git diff prompts.txt | grep -e '^\+' | tail -n +2 | sed 's/^+//' | sed '/^$/d')
  if [ -n "$COMMIT_MESSAGE" ]; then
    echo "$COMMIT_MESSAGE" > /tmp/gitmessage.txt
    git add prompts.txt
    git commit -F /tmp/gitmessage.txt
    rm /tmp/gitmessage.txt
  fi
done
```

You are working in a Jekyll blog repository that also contains a PHP-FIG standards guide as a submodule.

Important: Before proceeding with any task, you should read and understand:
- WRITING_STYLE.md for blog post formatting and style guidelines
- README.md for project overview and setup instructions
- TODO.md for pending tasks and future improvements

Key Project Components:
1. Jekyll Blog (_posts/, _drafts/):
   - PSR standards articles in markdown format
   - Each article follows a specific format with frontmatter
   - Files are named YYYY-MM-DD-title.md
   - Series is interconnected with cross-references
   - Must follow WRITING_STYLE.md guidelines:
     * Start with "Ahnii!"
     * End with "Baamaapii 👋"
     * Include time estimates in section headers
     * Maximum 4 tags in frontmatter

2. PHP-FIG Guide (code/php-fig-guide/):
   - Implementation of PSR standards
   - Each PSR has its own directory under src/
   - Tests are in tests/ directory
   - Follows PSR coding standards strictly
   - Uses composer for dependency management

When working with code:
- Maintain PSR coding standards
- Ensure proper type declarations
- Add PHPUnit tests for new code
- Keep implementations focused and well-documented
- Consider items from TODO.md when making changes

When working with blog posts:
- Follow WRITING_STYLE.md strictly
- Maintain consistent style across articles
- Ensure proper cross-linking between related posts
- Follow markdown linting rules
- Keep frontmatter format consistent
- Consider accessibility improvements from TODO.md

Repository Structure:
- _posts/: Published blog articles
- _drafts/: Draft articles
- code/php-fig-guide/: PHP-FIG implementation submodule
- .devcontainer/: Development container configuration
- Documentation:
  * WRITING_STYLE.md: Blog post guidelines

# RAG System Technical Architecture

## Project Overview
An application that allows users to play a role playing game where the stories are generated by the LLM and items and quests are remembered by the LLM.

## TechnicalOverview
Edge-first RAG system leveraging Cloudflare's infrastructure for a serverless, globally distributed architecture. All components are designed for edge deployment, ensuring minimal latency and maximum scalability.

## Infrastructure Components

       - /api/embed (embedding)
   - **BGE-large-en-v1.5 via Workers AI**
     - Embedding generation
     - Dimensionality: 768
     - Context window: 512 tokens

2. **API Structure**
   ```typescript
   // Worker API definitions
   interface ModelWorker {
     generate: (input: GenerationInput) => Promise<WorkersAIResponse>;
     embed: (input: EmbeddingInput) => Promise<Float32Array>;
     chat: (input: ChatInput) => Promise<WorkersAIResponse>;
   }
   ```

### Data Storage Layer
1. **Vector Store**
   - Cloudflare Vectorize
   - Indexes: 
     - Primary document chunks
     - Query caching
   - Configuration:
     - Dimension: 768 (matching BGE)
     - Metric: cosine similarity
     - Index type: HNSW

2. **Relational Storage**
   - Cloudflare D1
   - Schema managed by Drizzle ORM
   ```typescript
   // Core schemas
   interface DocumentMetadata {
     id: string;
     title: string;
     chunks: ChunkMetadata[];
     evaluationScores: EvalMetrics;
   }

   interface EvalMetrics {
     retrievalQuality: number;
     generationQuality: number;
     timestamp: Date;
   }
   ```

3. **Object Storage**
   - Cloudflare R2
   - Use cases:
     - Raw documents
     - Evaluation artifacts
     - Synthetic datasets

4. **Cache Layer**
   - Cloudflare KV
   - Real-time metrics
   - Query results
   - Embedding cache

## Application Architecture

### Edge Workers
1. **Query Processing Worker**
   ```typescript
   export default {
     async fetch(request: Request): Promise<Response> {
       const { query, options } = await request.json();
       
       // Embedding generation
       const embedding = await AI.embed(query);
       
       // Vector search
       const context = await vectorize.search(embedding);
       
       // Response generation
       const response = await AI.generate({
         context,
         query,
         options
       });

       return new Response(JSON.stringify(response));
     }
   };
   ```

2. **Document Processing Worker**
   ```typescript
   export default {
     async fetch(request: Request): Promise<Response> {
       const document = await request.blob();
       
       // Process document
       const chunks = await processDocument(document);
       
       // Generate embeddings
       const embeddings = await Promise.all(
         chunks.map(chunk => AI.embed(chunk))
       );

       // Store in Vectorize
       await vectorize.insert(embeddings);

       return new Response('Processing complete');
     }
   };
   ```

3. **Evaluation Worker**
   ```typescript
   export default {
     async fetch(request: Request): Promise<Response> {
       const { type, data } = await request.json();
       
       switch(type) {
         case 'retrieval':
           return evaluateRetrieval(data);
         case 'generation':
           return evaluateGeneration(data);
         case 'synthetic':
           return generateSyntheticData(data);
       }
     }
   };
   ```

### Frontend
- Next.js 14 App Router
- Cloudflare Pages deployment
- Server Components for:
  - Data fetching
  - Streaming responses
  - Real-time metrics

## Evaluation System

### Synthetic Data Generation
```typescript
interface SyntheticDataGeneration {
  worker: AI.WorkersAI;
  
  async generateContent(config: GenerationConfig): Promise<SyntheticData> {
    // Generate using Mixtral via Workers AI
    const content = await this.worker.generate({
      prompt: config.template,
      parameters: config.parameters
    });

    // Validate and store
    return this.processAndStore(content);
  }
}
```

### Evaluation Pipeline
1. **Retrieval Evaluation**
   - Context relevance scoring
   - Precision/recall metrics
   - Response time tracking

2. **Generation Evaluation**
   - Answer quality assessment
   - Source verification
   - Factual consistency

3. **System Metrics**
   - Edge latency tracking
   - Cache hit rates
   - Worker performance

## Development Environment
