get-available-destinationsUse this when you need the list of available travel destinations before performing a tour search. Returns all available destination codes and names. ALWAYS call this tool FIRST before using tour-search to understand which destinations are available and get their correct codes.
tour-searchUse this when the user asks about tour packages, travel deals, or vacation planning. IMPORTANT: If you haven't retrieved the destination list yet in this conversation, call 'get-available-destinations' first. If you already have the destination list from earlier in this conversation, do NOT call it again - reuse the cached list. Default: Tokyo departure. For vague dates (e.g., 'around December'), uses mid-month dates with ±7 days flexibility and realistic trip duration based on destination (Hawaii: 7 days, Korea/Taiwan: 3 days).

priceFromnumberMinimum price in JPY per person (per adult). CRITICAL: This is ALWAYS price per adult. If user says total budget (e.g., '2 adults with 500,000 yen budget'), you MUST divide by number of adults: 500,000 ÷ 2 = 250,000 per person. Example: 'under 100,000 yen per person' → priceTo: 100000. Example: '2 adults with 500,000 yen budget' → priceTo: 250000.

travelDateFlexibilitystringFlexible date range options. CRITICAL: When user says vague dates like 'around December' or 'in December', you MUST use 'PLUS_MINUS_7DAY'. This is MANDATORY for vague dates. Use 'FIXED' ONLY when user specifies exact dates like 'December 25, 2025'. Default: 'PLUS_MINUS_7DAY'.
FIXEDPLUS_MINUS_1DAYPLUS_MINUS_2DAYPLUS_MINUS_3DAYPLUS_MINUS_7DAYtravelDateFromstringStart date of travel in YYYY-MM-DD format. IMPORTANT: When user says vague dates like 'around December' or 'in December', use the 15th of that month (e.g., '2025-12-15' for December). This represents mid-month and works well with PLUS_MINUS_7DAY flexibility. Calculate from current date when user says relative dates like '30 days from now'. Always use ISO format YYYY-MM-DD. Example: 'around December' → '2025-12-15'.
travelDateTostringEnd date of travel in YYYY-MM-DD format, must be after travelDateFrom. IMPORTANT: When dates are vague (e.g., 'around December'), calculate based on destination distance: Taiwan/Korea/nearby Asian countries = 2 days after travelDateFrom (e.g., 2025-12-15 → 2025-12-17 for 3-day trip), Hawaii/distant destinations = 7 days after travelDateFrom. For specific 'X nights Y days', use NIGHTS (X): travelDateTo = travelDateFrom + X days. Example: 'around December, Taiwan' → from '2025-12-15' to '2025-12-17'. Always use ISO format YYYY-MM-DD.
