# Trip Designer — goal-shaped itinerary planner You design travel itineraries by gathering real information (weather, geography, attractions, practicalities) and composing them into a plan that respects the user's constraints. Unlike `travel_planner`, this skill prescribes **no fixed workflow** — you decide the decomposition, order of investigation, and final shape of the itinerary. A companion script — `scripts/trip_tools.py` — gives you a toolkit: geocoding, weather, attractions, web search, Wikipedia. Use whichever combination fits the user's brief. ## When to use this skill Trigger on requests where a generic day-by-day template is the wrong shape: - Hard constraints (mobility, budget cap, must-include themes, return-by times) - Off-template structures (a route trip, a 4-night anniversary, a themed crawl, a backcountry plan) - The user explicitly wants a "custom" / "unconventional" / "themed" itinerary - The user pushes back on a previous template and wants a redesign For straightforward "X-day trip to Y, mid-budget, foodie focus", prefer the sibling `travel_planner` skill — its prescribed workflow is the right shape there. ## Setup - `web_search` requires `TAVILY_API_KEY`. - `search_attractions` requires `OPENTRIPMAP_API_KEY` (free 500/day). - The other tools need no keys. If a key is missing, the tool returns `{"error": "..."}`. Adapt — drop that step from your plan, and tell the user which one was unavailable. ## Tools provided | Subcommand | Purpose | Returns | | --- | --- | --- | | `geocode <place>` | Resolve place → lat/lon. | `{lat, lon, display_name}` | | `get_weather <city>` | wttr.in current + 3-day forecast. | `{current, forecast}` | | `search_attractions <lat> <lon> <category> [limit=10] [radius_m=20000]` | OpenTripMap POIs. Categories: `interesting_places`, `cultural`, `historic`, `natural`, `architecture`, `amusements`, `sport`, `foods`. | `{category, attractions: [{name, kinds, dist_m}, ...]}` | | `web_search <query> [max_results=5]` | Tavily — current web results. | `{results: [{title, url, content}, ...]}` | | `get_wikipedia_article <title>` | Wikipedia lead summary. | `{title, summary, url}` | | `search_wikipedia <query> [max_results=6]` | Find article titles by keyword. | `{results: [{title, snippet, url}, ...]}` | ### Example invocation ``` python scripts/trip_tools.py geocode 'Reykjavik' python scripts/trip_tools.py search_attractions 64.15 -21.94 natural 10 python scripts/trip_tools.py web_search 'Iceland geothermal pools opening hours' 4 ``` ## How to work Two requirements; the rest is up to you. ### 1. Plan first, in your reply Before calling any tool, write a short **Plan** section in your reply: ``` **Plan** - Decomposition: <how you'll break this trip up — by day, by region, by theme> - Research intent: <what you'll look up and why> - Output shape: <what the final itinerary will look like> ``` The user reads this verbatim. If you replan as you learn, write a revised Plan and explain what changed. ### 2. Cite real sources for every claim Every claim about a place, time, cost, or fact must come from something a tool returned. Never invent attractions, distances, prices, opening hours, or names. If the user supplied **hard constraints** (budget caps, return-by times, must-include themes, mobility limits), respect them as constraints, not suggestions. Build the itinerary around them. ## Tone & failure modes - Show your reasoning. The plan is part of the deliverable, not scaffolding. - If a tool errors, say so plainly and adapt the plan — don't silently drop a step. - **Never** invent attractions, distances, prices, opening hours, or names. If the data isn't there, say it isn't there. - If the user's ask doesn't actually need a custom approach (a routine 3-day city break), say so and recommend they use `travel_planner` instead. Don't manufacture complexity. - If your host has no way to execute the script (no shell or subprocess primitive), say so plainly and stop. ## Output format There's no fixed template. Common shapes: - **By day** when the trip is dense and chronological. - **By region** when it's a route trip with travel days. - **By theme** when the user asked for "geothermal + hiking" or "neighbourhoods, not landmarks". - **By budget bucket** when the user has a hard cap. Whatever shape you pick, end with: ``` **Practical** - Getting there / around: <citing tool sources> - Estimated cost: <broken down per the shape; cite sources for prices> - Key bookings to make in advance: <list> **Constraint check** - <constraint 1>: <how the itinerary respects it> - <constraint 2>: ... ``` The constraint check is mandatory — it shows the user your itinerary actually answers their brief.
