+🛠️ 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
+- ✅ Context-aware city detection (uses tenant_id from UI dropdown)
