Intelligent Travel Itinerary Planner

Problem it targets

Trip planning often fails on concrete constraints rather than attraction lists: how to order multiple cities without backtracking, how many main stops are reasonable for seniors or children, and which transport, lodging, and ticket costs change the per-person budget. This skill treats those inputs as structured fields instead of expecting a complete request up front.

How the skill works

It starts by collecting required inputs: origin, destination(s), and trip duration or date range. Then it refines the plan using group size, budget, transport preference, lodging preference, interests, pace, and special requirements.
- Through-route travel: chains cities between origin and destination
- Loop travel: forms a closed circuit with the same start and end point
- In-depth travel: builds day-level detail for one destination
- Themed travel: organizes stops around food, hiking, culture, or another theme
The output includes a trip overview, daily itinerary, and optional cost estimate. After planning, it adds practical notes on combining attractions, season suitability, schedule adjustment, and tools, with emphasis on nearby routing, 3-4 major stops per day, and buffer time.

Limits and caveats

It is best for constraint-aware route design, not real-time booking, weather lookup, or hotel availability checks. Missing budget, pace, or traveler composition can make the plan generic, while accessibility, halal, or vegetarian needs should be specified early to avoid rework. references/planning-guide.md describes the through-route method, themed design, and cost estimation, but final quality depends on input completeness.
