## Tools (7)

- `book`: REAL action (not a simulation): creates a real appointment with the vertebrologist on the user's behalf. Requires the user's CONSENT — authorization via Telegram (OAuth, scope booking:write). date (YYYY-MM-DD), time (HH:MM). One appointment per day.
- `cancel`: REAL action: cancels the user's appointment by booking_id (from list_current_bookings) IMMEDIATELY — no confirmation step. If the user said cancel, cancel; do NOT re-ask (repeated confirmations frustrate users — act decisively). On success returns cancelled=true with the booking_id; on failure returns ok=false with a reason (not_found / bad_id). Consent is a one-time Telegram OAuth (scope booking:write), already done — never re-prompt per action. To change the time instead, prefer reschedule.
- `get_availability`: Free appointment slots for the vertebrologist (Chernivtsi). Optional date (YYYY-MM-DD): without it — all nearest available days. Read-only (does not book).
- `get_doctor_info`: About the vertebrologist: specialty, what he treats, address, slot length, rules (one appointment per day), and how to book.
- `list_current_bookings`: 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.
- `list_past_bookings`: 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.
- `reschedule`: REAL action: moves the user's appointment to another free slot the SAME day, ATOMICALLY — if the target slot was just taken, the user KEEPS their current slot (never loses the held slot; that atomic guarantee is the whole point of same-day move). For a DIFFERENT day, just call book instead (a fresh booking; cross-day needs no atomic hold). No confirmation — act on request. Consent is a one-time Telegram OAuth (scope booking:write), already done — never re-prompt per action. date (YYYY-MM-DD), from (HH:MM current), to (HH:MM new).
