+2. Geocode any addresses to get coordinates (use search_and_geocode_tool)
+3. Prepare the optimization request:
+   - Convert stops to shipments format (each stop is a delivery)
+   - Set source=first and destination=last (or use specified start/end locations)
+   - Use profile: mapbox/${profile}
+4. Call optimization_tool with the shipment configuration
+5. Display the results:
+   - Show the optimized route on a map with numbered waypoints
+   - Provide the optimized order of stops
+   - Show total distance and estimated time
+   - Compare against the original order (if applicable):
+     * Time saved
