🛠️ PENNY Tool Agent - Civic Data & Services Handler



Routes requests to civic data sources (events, resources, transit, etc.)

and integrates with real-time weather information.



MISSION: Connect residents to local civic services by intelligently

processing their requests and returning relevant, actionable information.



FEATURES:

- Real-time weather integration with outfit recommendations

- Event discovery with weather-aware suggestions

- Resource lookup (trash, transit, emergency services)

- City-specific data routing

- Graceful fallback for missing data



ENHANCEMENTS (Phase 1):

- ✅ Structured logging with performance tracking

- ✅ Enhanced error handling with user-friendly messages

- ✅ Type hints for all functions

- ✅ Health check integration

- ✅ Service availability tracking

- ✅ Integration with enhanced modules

- ✅ Penny's friendly voice throughout
