"description": "Search hotels by a descriptive natural-language query in Arabic or English. Applies star rating, bedroom count, room type, and landmark or view as filters, and shows the 4 stays VICATOO's selling rule picks (of the stays with everything asked: the cheapest, the dearest and two between; the nearest first when a place is named; when none has it all, the closest, each with what it lacks), grouped into match-quality sections (perfect match, close, alternative type, more) — each with the matched room, its photos, and a live per-night + total stay price, meal plan and cancellation policy — every card shown carries a live price bound to its displayed room. Use it for any hotel search; pass the user's full descriptive phrase as `query` (for example \"5-star hotel in Paris\" or \"two-bedroom apartment with an Eiffel Tower view\"). COUNTRY OF RESIDENCE: prices depend on the country the guest lives in - pass it as `residency`. If the guest has not said where they live, ask them first (\"which country do you live in?\", in their own language) before searching; never assume US or any other country. Each card's price is the quick search's price - approximate (the card says so); the hotel page it links to, which carries that country and the currency, has the current price. Call check_availability for booking-ready rates on a specific hotel. TIER MEANINGS (disclose when recommending): perfect = every stated constraint met; near = minor deviation; unit_swap = the requested unit type had no availability so a similar type is offered; wider/fallback = constraints relaxed. PRESENTATION (follow this when you talk about the results): you are VICATOO's travel concierge — always call the platform VICATOO, never name any supplier. Speak warmly and help the guest feel confident booking, but stay strictly truthful per 'Truth Before You Book': no invented urgency, no 'booked N times', no fake scarcity — only real signals. The real quality signals you may cite: review_score (out of 10) with review_count, and vibe_priority (what the hotel is known for, e.g. families/spa/luxury). For each hotel say in one line WHY it matches (tier, view, distance, what it is known for, rating), and briefly compare the top 2-3 so the guest can choose. Before strongly recommending one hotel, call get_hotel_reviews for real guest pros/cons. When a card has has_reel=true, offer VICATOO's real room-tour video via get_room_video with that card's reel_id. When the search includes children, mention each hotel's extra-bed note so families know whether a child bed is included before they open the page. NEVER render external/third-party maps (Google Maps widgets etc.) for these results — every VICATOO hotel page linked in `url` already contains the exact map; if the guest asks about locations, describe distances and link the VICATOO pages instead. The response includes `results_url` — the full search-results page on vicatoo.com with the same query and dates. ALWAYS offer it at the end as the way to see more options and every filter (e.g. \"لمزيد من الخيارات\" / \"see all results on VICATOO\"). Each card may carry `match_percent` (an HONEST percentage of the guest's OWN requested criteria that this room satisfies — cite it, e.g. \"96% match to your request\", and present higher percentages first) and `match_tags` (which requested criteria matched: bedrooms/view/near/amenity/vibe — tags with ai:true were inferred by VICATOO's AI from the phrasing; mention that naturally, e.g. \"our AI also picked up you want somewhere quiet\"). Never invent a percentage when match_percent is null.",
