Vehicle makeIds and modelIds lookup

fetch-vehicle-models
Full Description

Use this tool to retrieve vehicle makeIds and modelIds unique identifiers for a given vehicle type and make name. This is a preparation step for listing search: when user intent is to find/buy/search vehicles, call this tool first and then call 'vehicle-carousel' with the returned unique identifiers. Do not end the workflow after this tool because it does not return listings.

Vehicle-carousel

vehicle-carousel
Full Description

Search for vehicle listings for sale, rent, or lease in Luxembourg on luxauto.lu using user criteria. MANDATORY CALL ORDER WHEN A MODEL NAME IS MENTIONED:

  • If the user mentions model text (examples: 'Aprilia RS', 'BMW X5', 'Golf'), first call 'fetch-vehicle-models' to resolve makeIds and modelIds.
  • Then call 'vehicle-carousel' immediately after with the returned makeIds and modelIds'.
  • Never stop after 'fetch-vehicle-models' when the user asks to find/buy/search vehicles, because that tool does not return listings.
  • If no makeIds and modelIds match, still call 'vehicle-carousel' with make + other user filters.

Use this tool when the user wants to see matching listings such as:

  • Cars, motorcycles, or vans matching criteria
  • Price, mileage, year, make/model, fuel, or gearbox searches

Key expected inputs:

  • Vehicle type (vehicleId: 1 car, 2 motorcycle, 9 van)
  • One or more makes and optional modelIds(from 'fetch-vehicle-models')
  • User-specified filters (price range, mileage, year, fuel, gearbox, options)
  • Optional: Category/body style, colors, or seats

Output intent: Returns a carousel with up to 20 vehicles matching criteria with details like first photo, make/model, price, year, mileage, fuel, gearbox. What it does not do:

  • No financing recommendations or financial advice
  • No suggestions on which vehicle to choose
  • No adding search criteria the user did not explicitly mention
