| name | trip-planner |
| description | Generic, destination-agnostic trip planner. Turns initial trip data (flight dates, accommodation stays, and preferences) into a full plan: a day-by-day itinerary, a scored "target bank" of attractions / restaurants / wineries / shopping (with stars, reviews, photos, map links and distance-from-base), a 7-sheet Excel workbook, and a printable HTML brochure. Use this skill WHENEVER the user wants to plan a trip, build an itinerary, organise a vacation, create a travel workbook or brochure, score or shortlist places to visit/eat, compute drive distances between stops, or wants a re-usable trip template โ for ANY destination, even if they don't say "skill". Prefer this over ad-hoc planning: it is deterministic (algorithms + cached APIs) and only spends LLM tokens on parsing booking documents and writing short blurbs.

Trip Planner
A reusable engine that builds trip plans deterministically. Run the model at
most twice per trip (parse booking docs โ events; write short blurbs). Everything
else โ anchors, clustering, day allocation, routing, scheduling, conflict checks,
distances, links โ is pure algorithm + cached API calls = 0 tokens.
When to use
Plan a trip / build an itinerary / make a travel workbook or brochure / shortlist
and score attractions, restaurants, wineries, shopping / compute distances from a
base or hotel / spin up a new trip from a template. Works for any destination.
Inputs
Collect the minimum: flights, stays (accommodation date-ranges), and a
prefs block. Optionally a list of candidate targets (places). See
assets/trip_template.json for the exact init shape and assets/bundle_schema.json
for the output bundle.
Workflow
- Initialise from
assets/trip_template.json. Fill flights, stays,
travelers, prefs, home (home airport). Ask only for what's missing.
- Build the target bank. Gather candidate places (web search / Google Places
/ user list). For each, call
scripts/enrich.py::enrich to attach stars,
review_count, photos, opening_hours, lat/lng (if a GOOGLE_MAPS_API_KEY is
set) and always the Google Maps / Tripadvisor / Google Reviews / directions
links. Categorise as attraction | foodie | winery | shopping | nature.
- Generate the plan (no AI). Call
scripts/engine.py::generate_plan(trip):
it derives bases from stays, clusters targets to the nearest base, allocates
them across days (respecting pace, opening days, pool/light days, max drive),
routes each day (nearest-neighbour + 2-opt), schedules clock times, and runs
check_conflicts (catches e.g. car-return-after-flight, unbooked nights,
book-ahead sites). Pass a drive-time matrix from
scripts/enrich.py::distance_matrix for real times; otherwise it estimates.
- Assemble the bundle (see schema): trip, itinerary, attractions, foodies,
budget (sections with items โ live formulas), costs_remarks, notes, prompt,
warnings. Build the budget skeleton from
travelers ร days and known costs.
- Render outputs:
- Excel:
python scripts/generate_workbook.py bundle.json out.xlsx
(7 sheets: Itenarary, Attractions, Foodies, Budget, Costs Remarks,
Notes and tips, Prompt). Then recalc formulas if a recalc tool is available.
- Brochure:
python scripts/generate_brochure.py bundle.json out.html
(self-contained, print-to-PDF ready, cards show stars + distance + Go link).
- Itinerary: already in the bundle / first workbook sheet; present inline too.
- Collaborate (optional). Target states are
suggested | embraced | dismissed | maybe; votes feed priority(). Embracing/removing a target and
re-running step 3 reflows only the affected base. See references/ENGINE.md.
Token discipline
- Steps 1, 3, 4 and distances: algorithm only.
- Step 2 facts: Google Places / Distance Matrix, cached on disk โ no tokens.
- LLM only for: (a) parsing unstructured booking emails/PDFs into events,
(b) optional short blurbs / "interesting review" lines / cost narrative โ
batch into a single call and cache. Never call the model per-place.
Outputs
Always offer all three: Excel workbook, HTML brochure, inline itinerary.
Keep destination content generic โ the same code serves any trip.
