Rudko — vertebrologist (Chernivtsi, Ukraine)

Creates a real appointment with the vertebrologist on the user's behalf. Takes date (YYYY-MM-DD) and time (HH:MM), both required; the slot must be one returned by get_availability. Returns ok=true with the booked date and time, or ok=false with a reason: taken (the slot is no longer free; the call fails rather than quietly moving the user to a different time), day_limit (this patient already has an appointment that day — the limit is one per calendar day), locked (the doctor closed that day or slot), past, invalid, error. Authorization required: a one-time Telegram OAuth consent with scope booking:write, which also covers later calls.

Cancels the user's appointment by booking_id, as returned by list_current_bookings. Returns ok=true with cancelled set to that booking_id, or ok=false with a reason: not_found (no such appointment for this user) or bad_id (not a valid UUID). A cancellation is reversible — the freed slot can be booked again — which is why this tool is not marked destructive. To change the time instead of giving the appointment up, reschedule moves it atomically within the same day. Authorization required: the one-time Telegram OAuth consent (scope booking:write), which also covers later calls.

Free appointment slots for the vertebrologist (Chernivtsi). Optional date (YYYY-MM-DD): without it — all nearest available days. Read-only (does not book).

About the vertebrologist: specialty, what he treats, address, slot length, rules (one appointment per day), and how to book.

The user's current/upcoming appointments (booking_id, date, time, status), nearest first. Cancelled ones are ALSO shown — tell them apart by the status field ('booked' | 'cancelled'). Needed to reschedule/cancel. Requires authorization.

The user's past appointments (booking_id, date, time, status), most recent first. limit (default 20) and offset for pagination. Cancelled ones are ALSO shown — by the status field. Requires authorization.

Moves the user's appointment to another free slot on the same day, atomically. Takes date (YYYY-MM-DD), from (HH:MM, the slot held now) and to (HH:MM, the new slot). Returns ok=true with moved_to, or ok=false with a reason: taken (the target slot was taken in the race — the user keeps the slot they already held, so either outcome leaves them with an appointment — that is the point of the atomic move), not_found, invalid, error. A move to a different day is a fresh booking and needs no atomic hold, so book is the right call for that. Authorization required: the one-time Telegram OAuth consent (scope booking:write), which also covers later calls.
