Modules

• src/config.py - Configuration management with strict validation
• src/exceptions.py - Custom exception hierarchy
• src/scraper.py - Web scraping (RSS/Atom/HTML)
• src/image_analyzer.py - GPT-4 Vision image analysis
• src/aggregator.py - Content aggregation and prompt generation
• src/article_client.py - Node.js API client
• src/publisher.py - RSS/JSON publishing

Installation

# Create virtual environment
python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements.txt

# Configure environment
cp .env.example .env
# Edit .env with your API keys

Configuration

Required environment variables in .env:

OPENAI_API_KEY=sk-your-key-here
NODE_API_URL=http://localhost:3000
NEWS_SOURCES=https://techcrunch.com/feed,https://example.com/rss

See .env.example for all options.

Usage

# Run the pipeline
python scripts/run.py

Output files:

• output/feed.rss - RSS 2.0 feed
• output/articles.json - JSON export
• feed_generator.log - Execution log

Type Checking

# Run mypy to verify type safety
mypy src/

# Should pass with zero errors

Testing

# Run all tests
pytest tests/ -v

# With coverage
pytest tests/ --cov=src --cov-report=html

Code Quality Checks

All code follows strict Python best practices:

• ✅ Type hints on ALL functions
• ✅ No bare except: clauses
• ✅ Logger instead of print()
• ✅ Explicit error handling
• ✅ Immutable dataclasses
• ✅ No global state
• ✅ No magic strings (use Enums)

Documentation

• ARCHITECTURE.md - Technical design and data flow
• CLAUDE.md - Development guidelines and rules
• SETUP.md - Detailed installation guide

Development

This is a V1 prototype built for speed while maintaining quality:

• Type Safety: Full mypy compliance
• Testing: Unit tests for all modules
• Error Handling: Explicit exceptions throughout
• Logging: Structured logging at all stages
• Configuration: Externalized, validated config

Next Steps

1. Install dependencies: pip install -r requirements.txt
2. Configure .env file with API keys
3. Run type checking: mypy src/
4. Run tests: pytest tests/
5. Execute pipeline: python scripts/run.py
