Key Components

1. Background Service Worker: Orchestrates form filling, manages profiles, and coordinates between components

2. Content Script: Detects ATS platforms, analyzes DOM structure, performs autofill operations, and handles navigation

3. Field Mapper: Contains platform-specific rules and heuristic-based field detection with AI fallback

4. Answer Library: Manages templates for recurring questions and custom responses

🔧 Development

Code Structure

• Modular Design: Each component is self-contained with clear interfaces
• Vanilla JavaScript: No external frameworks for maximum compatibility
• Comprehensive Comments: Detailed documentation throughout the codebase
• TODO Markers: Clear indicators for future enhancements

Extending Support

1. Adding New ATS Platforms

   • Update manifest.json with new URL patterns
   • Add detection rules in src/lib/ats-detection/ats-detector.js
   • Create field mapping rules in src/lib/field-mapper/

2. Custom Field Detection

   • Extend heuristic rules in field-mapper.js
   • Modify LLM integration for complex cases

Testing

• Load the extension in developer mode
• Test on various ATS demo sites
• Verify form field detection and filling
• Check file upload functionality

🔒 Privacy & Security

• All data stored locally using Chrome's storage API
• No data transmitted to external servers (except LLM API calls)
• Screenshot data captured only for user's local records
• API keys should be rotated in production environments

📝 TODO & Future Enhancements

• Enhanced AI integration for complex form layouts
• Backend event logging and analytics
• Multi-language support
• Advanced field validation
• Bulk application management
• Integration with job boards and LinkedIn
• Machine learning for improved field detection
• A/B testing for form completion strategies
