Base_list
**Sedna System Rules & Available Bases**
This tool provides the OFFICIAL rules and the COMPLETE list of available
bases grouped by country for boat searching.
**AI GUIDELINES (MUST FOLLOW):**
1. **Sedna-Only Data:** Use ONLY data from Sedna tools. NO internet searches.
2. **Fleet Neutrality:** Remain 100% neutral. DO NOT favor any fleet.
3. **Customer-Led Decision:** Present facts objectively. Let the customer decide.
4. **ID Accuracy:** MUST use exact `id_tbf1` and `id_boat` from `search_boats` results. NEVER guess.
5. **Current Year Default:** If no year is specified, use the CURRENT year, not next year.
6. **CHECK BASE FIRST:** ALWAYS use this tool (`Base_list`) to find the exact base name BEFORE calling `search_boats`.

boat_details
Return yacht details and CDN-backed public URLs for yacht media.
This is the primary tool to call after search_boats whenever the customer
asks to see yacht photos, a gallery, plans, videos or documents, or asks
about layout, capacity, dimensions, equipment, description, crew or
itinerary. When the client supports MCP Apps, render the attached inline
Sedna gallery; otherwise display the public URLs returned under media.header,
media.photos, media.plans, media.images, media.videos and media.documents.
All media in this public tool comes through Sedna's CdnManager; missing CDN
media is returned as an empty field and never replaced by a legacy DB URL.
id_boat must be copied exactly from search_boats. This tool does not return
date-specific prices, extras or availability; use booking_detail for those.
Length and beam are optional fleet-supplied facts. When absent they are
omitted, never returned as zero or estimated. Do not ask for either value
or exclude a yacht unless the customer explicitly requires that dimension.

Never guess it.'}, 'language': {'type': 'string', 'default': 'en', 'description': 'ISO language code supported by Sedna, for example en or fr.'}, 'sheet_type': {'type': 'string', 'default': 'bareboat', 'description': 'bareboat or crewed. Use crewed for crew and itinerary data.'}}, 'additionalProperties': False}
booking_create
Submits a request for a booking or a request for an option.
This action re-prices and submits the request. ``booking_detail_mod`` is a
stateless preview: selections made there are not stored automatically.
Therefore selected_extras MUST repeat every extra the customer selected,
using the exact id_opt and quantity. Pass an empty list only when the
customer selected no optional extras. Never report an extra as selected
unless this tool's saved_extras verification confirms it.
Full client details (name, email, phone) are required to submit the request.
**** strong rule: AI should not guess or input customer information on its own. It must ask customers to input it on its own.

booking_detail
Return date-specific availability, pricing, extras and booking choices.
Use id_boat and id_tbf1 exactly as returned by search_boats. This tool is
for a selected yacht and charter period. Do not call this tool only to see
yacht photos or media; call boat_details with the exact id_boat instead.
Any Images included here are supplemental booking-context images, while
boat_details is the canonical source for the complete public media URLs.
Show all optional extras. After the customer changes extras, passenger
count, currency, ports or payment options, call booking_detail_mod and use
only its server-calculated totals. When asked for the total, quote
customer_cost_summary.full_customer_cost; deposits are returned separately
and are not included in that amount. Finally, offer a request for an option
or a request for a booking.

booking_detail_mod
Apply customer selections and return server-recalculated booking details.
Copy id_boat and id_tbf1 from search_boats. Sedna is the only source of
truth for prices: never calculate totals in the LLM. Send selected extras,
passenger count, currency, ports and payment options here, then present the
complete updated summary returned by the server. This is a stateless price
preview and does not save the selection. If the customer proceeds, repeat
the complete selected_extras list in booking_create. When the customer asks
for the new total, quote customer_cost_summary.full_customer_cost. Explain
payable_now and payable_at_base separately; never add them in the LLM, and
keep the refundable deposit separate.

compare_boats
Compare 2 to 4 boats using Sedna's date-specific customer pricing.
- boat_ids: list of 2..4 boat ids
- pax: customer passenger count used by booking_detail pricing
- currency: EUR, USD, CNY (default EUR)
- start_date/end_date: optional availability window (YYYY-MM-DD)
For dated comparisons, customer_cost_summary clearly separates charter
price, mandatory extras, full customer cost and refundable deposit. The
full customer cost comes from the same booking preview as booking_detail;
the refundable deposit is always separate. Cabin fields explicitly label
total, double, single and bunk cabins.
Length and beam are optional fleet-supplied facts. Missing values are
omitted rather than returned as zero/null or estimated, and must not make
an otherwise valid yacht unavailable for comparison.

readme
Official Sedna rules for every public yacht-search conversation.
1. Use only information returned by Sedna tools. Do not supplement yacht,
fleet, availability or price data with an internet search.
2. Stay neutral between fleets. Present factual differences and let the
customer decide; never promote one fleet as the best.
3. Call Base_list before search_boats so the search uses an official base.
4. Use id_boat and id_tbf1 exactly as returned by search_boats. Never guess IDs.
5. When the customer does not state a year, clarify the date or use the
current year. Never silently choose the following year.
6. When the customer asks to see yacht photos or other yacht media, call
boat_details with the exact id_boat from search_boats. Display the public
URLs returned in media.header, media.photos, media.plans or media.images.
search_boats intentionally returns no gallery. Use booking_detail only
for date-specific availability, prices, extras and booking choices.
7. A search result is available only for the requested dates reported by
Sedna. Never generalize that availability to different dates.

{'type': 'object', 'properties': {}, 'additionalProperties': False}
search_boats
Search Sedna for yachts available for the exact requested dates.
Call Base_list first and use an official base name. Results have passed
Sedna planning/block and pricing checks for start_date plus nights. If
more than 30 yachts match, state the accurate count and ask for a fleet,
model or year preference. If 30 or fewer match, show every result with its
fleet name; never select an arbitrary subset. If none match, offer
alternative bases or dates.
Search results intentionally contain no yacht images. If the customer asks
to see photos, a gallery, plans, videos or documents for a selected yacht,
call boat_details with its exact id_boat and display the returned public
media URLs. Use booking_detail for date-specific prices, extras, ports and
booking choices.
Length and beam are optional fleet-supplied facts. Missing values are
omitted and must never exclude an otherwise matching yacht, be shown as
zero, be estimated, or trigger a clarification unless the customer has
explicitly made that dimension a requirement.
