Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Read-only tools for Château du Bû, a château hotel in Aurseulles (Calvados, Normandy, France). Use them to answer guest questions about room availability, the estate, and public events. IMPORTANT — do not compute availability yourself from raw counts. Call `check_room_availability`: a night can be free and still not be bookable (arrivals open from `earliest_check_in` — today or tomorrow depending on the day's same-day cut-off), and a multi-night stay needs the same room type free on every night. The tool applies both rules and returns a verdict. This server never books, pays, or returns personal data. To act, send the guest to https://chateaudubu.fr/en/hotel/reserver — or replace /en/ with the guest's language (fr, en, it, nl, de, es, pt, pl, hu, cs, ru, uk, zh, ko).

check_room_availability — Check room availability
Advertised by the server during the last successful anonymous check.
Advertised read-only

Answer 'can a party of N stay from DATE for N nights?'. Returns a verdict (bookable yes/no), the reason when no, the room COMBINATIONS that house the party, and the booking URL. Applies the house rules for you: the earliest arrival date (today or tomorrow, depending on the same-day cut-off), and a stay needs the same rooms free on every night. A party too large for one room is NOT a refusal — the house is sold as several rooms. Prefer this over reading the raw calendar.

Use for overviews ('when is there space in October?'); for a specific stay use check_room_availability. Aggregate counts only, no personal data. Read `generated_at` for the real age.
