Generate complete, executable travel itineraries in Chinese

This skill plans a full, executable multi-day trip itinerary in response to any travel request, running four ordered steps that cannot be skipped or reordered. Step 1 collects trip details in a single batched question (4-7 items): departure city, destination, dates/duration, travelers, and critically, budget - the skill will not output any itinerary, draft, or example until budget is confirmed, defaulting to a mid-tier "comfortable" budget only if the user explicitly declines to give one. Step 2 uses live web search to verify season, weather, transport prices and duration, accommodation options by budget tier, attraction hours/tickets/reservations, visa requirements, and local practicalities, labeling every fact with its source and query date. Step 3 builds the day-by-day framework against 13 explicit rules (R1-R13) - tiering sights into must-see/worth-it/optional, flagging overcommercialized tourist streets, sizing each day's load by scale rather than headcount, giving flagship attractions a full day of their own, adding time buffers, anchoring commute estimates to the chosen hotel, deduplicating repeated neighborhoods across nights, and treating high-priced subjective activities like shows or night cruises as opt-in extras capped at one per trip. Step 4 renders the result through a fixed Markdown template - overview, daily schedule, budget table, transport/lodging notes, attraction and food lists, a pre-departure confirmation checklist, a data-source index, and a rule-by-rule self-check table - always in Chinese, regardless of the request's language.

Use it for any travel, trip, or itinerary-planning request, even if the user doesn't say "plan" explicitly - it covers independent travel, family trips, trips with kids, business travel, and road trips. Do not expect an itinerary on the first message if budget hasn't been given: the skill deliberately withholds any plan, draft, or example until the user answers the budget question, and it refuses to silently drop must-see sights or add extra cities/day-trips without asking first.

Input: a single batched question covering origin city, destination, dates, travelers, budget tier (economy/comfortable/luxury) or a total/per-person figure, pace preference, interests, and constraints like visas or accessibility needs - destination scope is locked to exactly what the user specified, with any nearby day-trip additions requiring explicit sign-off. Output: a Chinese-language Markdown itinerary with an overview, a day-by-day schedule (morning/afternoon/evening/transport/backup plan), a budget table split by chosen tier, transport and lodging recommendations, a must-see/hidden-gem/avoid attraction and food list, a pre-departure confirmation checklist, a source index tying every live-queried fact to its origin and query date, and a completed rule-self-check table covering all R1-R13 planning rules plus five hard constraints.

Relies on WebSearch/WebFetch for live pricing, hours, weather, and visa data, explicitly ranking official sources such as tourism boards, government notices, and airline/rail sites over media, and treating social-platform "wild rankings" as leads only, never as citable facts.

Users planning any multi-day trip who want a fully-sourced, rule-checked itinerary rather than a quick suggestion list - the output itself is Chinese-only by design, so it best suits Chinese-language travel planning.
