THE TRIP — Travel Planning OS Brain

For trips that survive contact with reality. One orchestrator plus ten specialists that check every day against real transit times and opening hours, sequence bookings by cancellation risk, and leave room for the thing you did not plan.

What makes it different

Almost every itinerary that falls apart falls apart the same way. Day three had four stops that were each individually fine and collectively impossible. The feasibility script takes the day's stops with locations and opening hours, computes actual transit between them, and flags the days that only work if nothing goes wrong. It is unglamorous and it saves the holiday. The second thing it does is order your bookings by cancellation terms, so refundable things get booked first and the non-refundable ones wait until the shape has settled.

It ships working code, not just prompts feasibility.py

Walks each day stop by stop against transit time and opening hours, returns the slack remaining, and names the specific stop to drop on any day that runs negative. Then sorts the booking queue by cancellation exposure rather than by excitement. Every OS Brain in this drop carries its own executable component, so the judgement calls stay with you and the arithmetic stops being a matter of opinion. Runs anywhere Python runs, and the specialists still work on their own if you never open it.

Say it in plain words — it works out the rest

"Ten days, two adults, two kids"→ full pipeline, shape first
"Is this too much for one day?"→ 04 · it names the stop to drop
"When do I book what?"→ 06 · refundable first, always
"Our flight just got cancelled"→ 09 · contingency, already written
"The kids will melt down"→ 07 · pace built around them

Where it refuses to skip ahead

  • No itinerary without a feasibility pass — a plan assuming every connection holds is a plan that fails on day one.
  • Nothing non-refundable before the shape is fixed — booking order matters more than the choice of hotel.
  • One day stays empty — every trip needs the unscheduled day, and it is always the one people remember.
  • Never plan for everyone at their best — build for the tired version of your group, because that is who shows up.

The habit it is really selling: write the ledger on the flight home, while you still remember which restaurant was worth it. Single-seat license. Planning tooling, not a booking agent — visas, entry requirements, insurance and health guidance change constantly and need checking against official sources for your own nationality and route.
