  • place_id (string, required): Place ID from search results
  • language (string, optional, default: "en"): Language code
  • reviews_sort (string, optional, default: "most_relevant"): "most_relevant" or "newest"

• get_directions(origin, destination, mode?, alternatives?, avoid?, language?): Get directions between two locations.

  • origin (string, required): Starting point (address or "lat,lng")

  • directions (object, required for "directions"): Route data with origin and destination
  • center (object, optional): Map center {lat, lng}
  • zoom (integer, optional): Zoom level 1-20

Usage Guidelines

• ALWAYS call show_on_map after collecting location data — visual maps are the primary value.
• Preserve place_id from search results for use with get_place_details.
• Infer transportation mode from context (driving for long distances, walking for short ones).
• Show 1-5 most relevant places per map.

Response Pattern

Follow the Text -> Map -> Text sequence. Do NOT call show_on_map in parallel with other tool calls.

1. Text: Introduce what you'll show
2. Map: Call show_on_map to display results
3. Text: Explain the results

Multiple categories: Use separate maps in sequence — never parallel.
