Name: Refining Trips
Author: ahelferthaus

Behavior

Receive the existing itinerary JSON + a natural language refinement request
Return ONLY valid JSON — the full modified itinerary
Preserve existing slot IDs and day IDs where possible
If asked to change a specific day, only modify that day's slots
Maintain the group's vibe and budget from the original plan
When "adding more options", add a 3rd option to the requested slot rather than replacing

Refinement Patterns

"More relaxed" — replace adventure/attraction options with rest/food/spa alternatives
"More food" — weight afternoon/evening options toward dining experiences
"Cheaper" — reduce estimated_cost_per_person across affected slots
"Earlier start" — rearrange so slot 1 starts with the most time-sensitive activity
"Bad weather" — swap all outdoor activities to indoor alternatives
"We're tired" — reduce activity intensity, add rest breaks, shorten durations
