extract_user_profile_from_text
Lightweight fallback extraction from raw text.
This is mainly for debugging and fallback use.
It is NOT the preferred production path.
Preferred production path:
- external model understands raw text
- external model outputs standard UserProfile fields
- call update_user_profile_from_model(...)
输入模式
{'type': 'object', 'title': 'extract_user_profile_from_textArguments', 'required': ['text'], 'properties': {'text': {'type': 'string', 'title': 'Text'}}}
输出模式
{'type': 'object', 'title': 'extract_user_profile_from_textDictOutput', 'additionalProperties': True}
get_booking_offers
Get available hotel offers for the current session dates.
REQUIREMENT:

Get detailed information for a hotel.
Use this after search_hotels when the user asks for more details
about a recommended option.
输入模式
{'type': 'object', 'title': 'get_hotel_detailsArguments', 'required': ['session_id', 'hotel_code_or_name'], 'properties': {'session_id': {'type': 'string', 'title': 'Session Id'}, 'hotel_code_or_name': {'type': 'string', 'title': 'Hotel Code Or Name'}}}

输出模式
{'type': 'object', 'title': 'get_session_stateDictOutput', 'additionalProperties': True}
get_user_profile_schema
Return the strict standard schema for user_profile.
IMPORTANT:
- Only these standard UserProfile fields are allowed.
- No alias mapping is supported.
- city is NOT a profile field.
- checkin_date / checkout_date are NOT profile fields.
- Numeric budget constraints usually belong to search_hotels price_min/price_max.
Use this tool when the external model is unsure what fields are allowed.
输入模式
{'type': 'object', 'title': 'get_user_profile_schemaArguments', 'properties': {}}
输出模式
{'type': 'object', 'title': 'get_user_profile_schemaDictOutput', 'additionalProperties': True}

输出模式
{'type': 'object', 'title': 'health_checkDictOutput', 'additionalProperties': True}
ingest_user_message
Store raw user message into session context.
IMPORTANT:
This tool is no longer the main profile extraction path.
RECOMMENDED USE:
- store raw user text for context
- let the external model decide profile fields
- then call update_user_profile_from_model(...)
DEFAULT BEHAVIOR:
- append raw text into user_info
- do not aggressively infer profile fields
OPTIONAL:
- if use_fallback_extraction=True, run a lightweight fallback extractor
输入模式
{'type': 'object', 'title': 'ingest_user_messageArguments', 'required': ['session_id', 'message'], 'properties': {'merge': {'type': 'boolean', 'title': 'Merge', 'default': True}, 'message': {'type': 'string', 'title': 'Message'}, 'session_id': {'type': 'string', 'title': 'Session Id'}, 'use_fallback_extraction': {'type': 'boolean', 'title': 'Use Fallback Extraction', 'default': False}}}

输出模式
{'type': 'object', 'title': 'search_homestays_in_cityDictOutput', 'additionalProperties': True}
search_hotels
Search and recommend hotels.
USE THIS TOOL FOR:
- city-based hotel search
- main search intent
- direct numeric search constraints such as price_min / price_max
- explicit room or amenity filters
IMPORTANT:
- city MUST be passed here, not inside user_profile
- user_profile is for stable preferences, not for search location
- if dates are known, call update_stay_dates first
- if profile preferences are known, call update_user_profile_from_model first
RECOMMENDED ORDER:
1. start_session
2. update_user_profile_from_model (optional)
3. update_stay_dates (optional)
4. search_hotels(city=..., ...)
输入模式
{'type': 'object', 'title': 'search_hotelsArguments', 'required': ['session_id', 'city', 'main_interest'], 'properties': {'city': {'type': 'string', 'title': 'City'}, 'limit': {'type': 'integer', 'title': 'Limit', 'default': 3}, 'suitable': {'anyOf': [{'type': 'array', 'items': {'type': 'string'}}, {'type': 'null'}], 'title': 'Suitable', 'default': None}, 'amenities': {'anyOf': [{'type': 'array', 'items': {'type': 'string'}}, {'type': 'null'}], 'title': 'Amenities', 'default': None}, 'price_max': {'anyOf': [{'type': 'number'}, {'type': 'null'}], 'title': 'Price Max', 'default': None}, 'price_min': {'anyOf': [{'type': 'number'}, {'type': 'null'}], 'title': 'Price Min', 'default': None}, 'room_type': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Room Type', 'default': None}, 'rating_min': {'anyOf': [{'type': 'number'}, {'type': 'null'}], 'title': 'Rating Min', 'default': None}, 'session_id': {'type': 'string', 'title': 'Session Id'}, 'surroundings': {'anyOf': [{'type': 'array', 'items': {'type': 'string'}}, {'type': 'null'}], 'title': 'Surroundings', 'default': None}, 'main_interest': {'type': 'string', 'title': 'Main Interest'}, 'user_specific': {'type': 'string', 'title': 'User Specific', 'default': ''}, 'non_refundable': {'anyOf': [{'type': 'boolean'}, {'type': 'null'}], 'title': 'Non Refundable', 'default': None}, 'hotel_class_stars': {'anyOf': [{'enum': [3, 4, 5], 'type': 'integer'}, {'type': 'null'}], 'title': 'Hotel Class Stars', 'default': None}, 'exclude_hotel_codes': {'anyOf': [{'type': 'array', 'items': {'type': 'string'}}, {'type': 'null'}], 'title': 'Exclude Hotel Codes', 'default': None}, 'required_name_terms': {'anyOf': [{'type': 'array', 'items': {'type': 'string'}}, {'type': 'null'}], 'title': 'Required Name Terms', 'default': None}}}

search_restaurants_near_hotel
Search restaurants near a hotel.
输入模式
{'type': 'object', 'title': 'search_restaurants_near_hotelArguments', 'required': ['session_id'], 'properties': {'hotel_lat': {'anyOf': [{'type': 'number'}, {'type': 'null'}], 'title': 'Hotel Lat', 'default': None}, 'hotel_lon': {'anyOf': [{'type': 'number'}, {'type': 'null'}], 'title': 'Hotel Lon', 'default': None}, 'session_id': {'type': 'string', 'title': 'Session Id'}, 'hotel_index': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Hotel Index', 'default': None}, 'hotel_code_or_name': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Hotel Code Or Name', 'default': None}}}
输出模式
{'type': 'object', 'title': 'search_restaurants_near_hotelDictOutput', 'additionalProperties': True}
start_session
Create or replace a session.
PURPOSE:
- Initialize conversation state
- Optionally store stable user profile fields
DO:
- pass stable or semi-stable profile information in user_profile
- pass preferred_language if known
- call this before other hotel-related tools
DO NOT:
- do NOT put city inside user_profile
- do NOT put checkin_date or checkout_date inside user_profile
- do NOT put search filters inside user_profile
CORRECT WORKFLOW:
1. start_session(...)
2. update_user_profile_from_model(...) # optional
3. update_stay_dates(...) # optional
4. search_hotels(city=..., ...)
WRONG:
user_profile = {
"city": "New York",
"checkin_date": "2023-04-01",
"checkout_date": "2023-04-05"
}
RIGHT:
start_session(user_profile={"preferred_language": "en"})
update_stay_dates(checkin_str="2023-04-01", checkout_str="2023-04-05")
search_hotels(city="New York", ...)
输入模式
{'type': 'object', 'title': 'start_sessionArguments', 'required': ['session_id'], 'properties': {'user_id': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'User Id', 'default': None}, 'metadata': {'anyOf': [{'type': 'object', 'additionalProperties': True}, {'type': 'null'}], 'title': 'Metadata', 'default': None}, 'session_id': {'type': 'string', 'title': 'Session Id'}, 'user_profile': {'anyOf': [{'type': 'object', 'additionalProperties': True}, {'type': 'null'}], 'title': 'User Profile', 'default': None}, 'preferred_language': {'type': 'string', 'title': 'Preferred Language', 'default': 'en'}}}
输出模式
{'type': 'object', 'title': 'start_sessionDictOutput', 'additionalProperties': True}
update_stay_dates
Update session stay dates.
USE THIS TOOL FOR:
- check-in date
- check-out date
- nights-based date calculation
DO NOT:
- do NOT put dates inside user_profile
- do NOT try to pass dates through start_session user_profile
输入模式
{'type': 'object', 'title': 'update_stay_datesArguments', 'required': ['session_id', 'checkin_str'], 'properties': {'nights': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Nights', 'default': None}, 'session_id': {'type': 'string', 'title': 'Session Id'}, 'checkin_str': {'type': 'string', 'title': 'Checkin Str'}, 'checkout_str': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Checkout Str', 'default': None}}}
输出模式
{'type': 'object', 'title': 'update_stay_datesDictOutput', 'additionalProperties': True}
update_user_profile
Update session.user_profile using standard UserProfile fields only.
USE THIS WHEN:
- the caller already has structured profile fields
DO NOT PUT HERE:
- city
- checkin_date
- checkout_date
- raw numeric search constraints that belong in search_hotels
Preferred profile fields include:
- price_range
- budget_flexibility
- relationships
- travel_purpose
- hotel_style
- facilities_like
- surroundings_like
输入模式
{'type': 'object', 'title': 'update_user_profileArguments', 'required': ['session_id', 'user_profile'], 'properties': {'merge': {'type': 'boolean', 'title': 'Merge', 'default': True}, 'session_id': {'type': 'string', 'title': 'Session Id'}, 'user_profile': {'type': 'object', 'title': 'User Profile', 'additionalProperties': True}}}
输出模式
{'type': 'object', 'title': 'update_user_profileDictOutput', 'additionalProperties': True}
update_user_profile_from_model
Preferred path for profile extraction.
The external model should:
- read the user's natural language message
- decide which STANDARD UserProfile fields are supported by evidence
- send ONLY those fields here
HARD RULES:
- only standard UserProfile fields are allowed
- do NOT invent new fields
- do NOT put city here
- do NOT put checkin_date or checkout_date here
- omit uncertain fields instead of guessing
- numeric budget constraints usually belong to search_hotels price_min/price_max
GOOD EXAMPLE:
{
"relationships": "solo",
"travel_purpose": "leisure",
"hotel_style": "luxury",
"facilities_like": "breakfast, gym",
"surroundings_like": "downtown"
}
BAD EXAMPLE:
{
"city": "New York",
"checkin_date": "2023-04-01",
"checkout_date": "2023-04-05",
"budget": 100
}
输入模式
{'type': 'object', 'title': 'update_user_profile_from_modelArguments', 'required': ['session_id', 'extracted_user_profile'], 'properties': {'merge': {'type': 'boolean', 'title': 'Merge', 'default': True}, 'session_id': {'type': 'string', 'title': 'Session Id'}, 'extracted_user_profile': {'type': 'object', 'title': 'Extracted User Profile', 'additionalProperties': True}}}
