ask_snowdata
ChatGPTText-only Q&A grounded in SnowSure data (~1s). Use for open-ended questions, terrain %, expert-run counts, comparisons, and advice. NEVER use for photo/gallery/picture requests (→ get_resort_photos) or resort guide cards (→ get_resort_info). Does NOT render UI cards.
ask_snowsure
ChatGPTDeprecated alias for ask_snowdata — backwards-compatible for 90 days. Use ask_snowdata instead.
book_lodging
ChatGPTLodging near a resort via LUXSKI for the signed-in user. With a specific hotelName + checkIn + checkOut it PREBOOKS a live rate and returns a LUXSKI checkout URL to complete payment (we hold the rate + attribute the booking; we never charge). Without those it returns availability + a booking link. Requires a SnowSure user access token (OAuth). Payment always completes on LUXSKI.
compare_forecasts
ChatGPTCompare 14-day snow forecasts across 7 weather models (ECMWF, GFS, GEM, JMA, ICON, Météo-France, Met Norway) for a resort. Shows model agreement and uncertainty. Use for forecast reliability queries.
compare_passes
ChatGPTCompare ski passes on price, resort coverage, and value — the tool for "which season pass includes <resort> — Epic or Ikon?" (pass resortSlugs=[<resort>]). Optionally pass resortSlugs you plan to ski and tripDays to see which pass covers them and whether it beats buying window lift tickets.
compare_resorts
ChatGPTCompare 2–4 resorts side by side across snow, terrain, and live conditions — every value comes from the SnowSure conditions resolver/contract. Use for head-to-head stat questions phrased as either/or: "which gets more average annual snowfall, X or Y", "which has the greater vertical drop / higher base or summit elevation / bigger skiable area, X or Y", "which typically opens earlier, X or Y". Optionally restrict to specific dimensions.
find_best_powder
ChatGPTFind resorts with the freshest powder snow right now. Returns resorts sorted by 24-hour snowfall. Use for "where is it snowing?" or "fresh powder" queries.
find_flights_to_powder
ChatGPTComplete the trip: from a resort, find the nearest gateway airport(s) and get flight-search links from your home airport. The "get there" leg of the funnel — pair with find_best_powder / find_powder_trips (find fresh snow) → this → book_lodging (stay). Args: resort (slug, required — use search_resorts to resolve a name), optional origin (your home-airport IATA like DEN, or a city name).
find_pass_resorts
ChatGPTList the resorts on a ski pass, optionally filtered to a region — answers "is <resort> on the Ikon Pass" and "what resorts does the Epic Pass include". Returns names + SnowSure slugs you can pass to get_resort.
find_powder_trips
ChatGPTPowder trips you can BOOK: ranks resorts by their 14-day forecast (best chance of fresh snow in the bookable window) and returns handpicked luxury ski hotels at each — "where to go AND where to stay". Use for "where should I book for powder", "best powder trip this month", "book a ski trip with good snow coming". Optional vibe filter (lux | hip) shows only hotels handpicked into that tier; SnowSure shows Lux and Hip stays only. Each hotel carries an attribution-tagged booking link; booking completes on LUXSKI.
find_resorts_by_criteria
ChatGPTFind resorts matching specific criteria like minimum snow depth, elevation range, number of runs, or SnowSure rating. Advanced filtering for trip planning.
get_avalanche
ChatGPTCurrent avalanche danger bulletin for a resort's forecast zone (US, Canada, Switzerland in v1), relayed from the official warning service with the issuer + link. Returns 'no bulletin' when there's no forecast service for the area or it's off-season. NOT a substitute for the official bulletin or avalanche training.
get_destination
ChatGPTMulti-mountain destination hub (Niseko, Chamonix, Aspen Snowmass umbrella) with a table of member ski areas. Use ONLY when the user names the hub itself — NOT for photo gallery (→ get_resort_photos on a specific mountain slug) and NOT for resort guide cards (→ get_resort_info).
get_elnino_rankings
ChatGPTRanked El Niño ski resorts from SnowSure's 30-year fleet table. Filter by region (south-america, north-america, europe, asia, oceania) or tier (A prime / B favored / C ENSO-proof / D late bloomer / E timing play). Use for 'best El Niño resorts in Europe', 'where will it snow most in 2026-27', 'is El Niño good for the Alps'.
get_elnino_signal
ChatGPTResort-level El Niño / ENSO outlook from SnowSure's 30-year fleet dataset (559 ranked resorts). Returns rank, tier, strong/all-event signal, analog winters ('97-98, '15-16, '23-24), forecast paragraph, methodology note, and in-season scorecard when live. Use for ANY El Niño, ENSO, or 2026-27 winter-outlook question about a named resort. A pattern, not a promise — n=3 disclosed; D/E tiers are timing plays.
get_insights
ChatGPTGet categorized SnowSure intelligence insights (not just snow totals). Answers questions like season vs 5yr norm, last season powder leaders, model accuracy by region, longest dry spell, trend pulse. Filter by category or insightType=intelligence to skip simple leaderboards.
get_ml_trends
ChatGPTFetch SnowSure-unique ML/AI trend datasets from the public REST API. Use for powder-day leaders, bluebird-day leaders, bluebird predictions, improving/stable/declining score pulse, per-model accuracy weights, daily SnowSure score component history, global forecast trust, and powder/bluebird event logs. Start with dataset=catalog. Prefer get_insights for narrative intelligence cards; use this for raw rankings and time series.
get_monthly_snow
ChatGPTTypical snow for a resort MONTH BY MONTH, from ~30 years of ERA5 reanalysis — average snowfall, snow days, base and peak depth, and biggest storm, plus per-season totals. Use for date-choosing questions: 'what is February usually like at Vail', 'when should I go', 'is January or March better'. This is HISTORY, not a forecast and not a prediction — for the next 14 days use get_weather_forecast, and for right now use get_resort. Months with too little history are withheld rather than shown thin; every month returned carries yearsTracked so you can cite the evidence.
get_my_snow_report
ChatGPTPersonalized snow report for the signed-in user's saved resorts — live conditions for each, ranked best-first (open resorts with the freshest snow on top). Requires a SnowSure user access token (OAuth).
get_operating_risk
ChatGPTWill the lifts run? A 48-hour operating-risk estimate from the Open-Meteo forecast — wind-hold (gusts), visibility, cold (wind-chill), and heavy-snow control delays. Modeled guidance, NOT the resort's own operating decision — always check live lift status.
get_pass
ChatGPTDetails for a multi-resort ski pass (Epic, Ikon, Mountain Collective, …): operator, season pricing tiers, destination count, regions, and the buy link.
get_powder_reels
ChatGPTPowder Reels — SnowSure archived storm timelapses with verified accumulation data burned into the frames ("Proof of Powder"). Use for "how much did it snow at X last night", "show me the storm at Alta", "biggest powder days this season", or any request for storm footage / timelapse / receipts. Returns reels newest-first with watch links.
get_regional_summary
ChatGPTGet a summary of snow conditions across an entire region or country with statistics and top resorts.
get_resort
ChatGPTSingle-resort data with a REQUIRED card parameter that picks the interactive UI. card=guide → resort info card (elevation, lifts, season dates). card=photos → photo gallery carousel. card=snow → snow conditions card (score, depth, forecast). card=full → detailed markdown only, no card. "Resort guide" → card=guide. "Photos/gallery" → card=photos. "Conditions/forecast" → card=snow. Prefer get_resort_info / get_resort_photos when available (same cards).
get_resort_info
ChatGPTINTERACTIVE RESORT GUIDE CARD (Resort Info sidebar UI) — elevation, vertical, lifts, runs, skiable acres, average snowfall, season dates, ski passes, editorial description, hero/gallery carousel. REQUIRED when the user asks for: resort guide, mountain profile, resort info, lifts/runs/vertical/skiable area, season dates, ski passes, or "tell me about the mountain" (non-weather). Examples: "Aspen Mountain resort guide", "how many lifts at Jackson Hole". Do NOT use get_resort (that shows the snow conditions card).
get_resort_photos
ChatGPTINTERACTIVE PHOTO GALLERY CAROUSEL — official SnowSure resort photos (hero + Sanity gallery). REQUIRED for: photos, pictures, images, gallery, "show me photos of Vail/Aspen". Never use web search or inline images — call this tool. Do NOT use get_destination, get_resort_info, or ask_snowdata for photo requests.
get_road_access
ChatGPTDriving access for a resort — answers "do I need chains to get to <resort>" and "is the road to <resort> open": a SnowSure drive call, feeder-city Saturday drive times on the PGRI pilot, plus chain-control / mountain-pass / road-surface conditions on nearby highways (California via Caltrans, Washington via WSDOT, Oregon via ODOT TripCheck, Montana via MDT 511, Wyoming via WYDOT 511, Colorado via CDOT, Utah via UDOT, British Columbia via DriveBC, Ontario via Ontario 511, New England via Compass C2C, Virginia via VDOT 511, New Zealand via NZTA). Returns 'no road data' outside the covered area. Links to the official DOT map; the resort's road status is authoritative.
get_road_cameras
ChatGPTLive roadside DOT/CCTV camera stills on the highways near a resort — shows what the drive actually looks like right now (California via Caltrans, Washington via WSDOT, Mount Rainier NP via NPS, Oregon via ODOT TripCheck, Montana via MDT 511, Wyoming via WYDOT 511, Utah via UDOT, British Columbia via DriveBC, Maryland via CHART/iMAP, New England via Compass C2C, Virginia via VDOT 511, New Zealand via NZTA, Alpine Europe via NAPSPAN). Distinct from resort webcams. Returns 'no road cameras' outside the covered area; each camera includes a live image URL.
get_road_weather
ChatGPTMeasured roadside weather (RWIS) on the highways near a resort — surface + air temperature, visibility, wind, precipitation (Colorado via CDOT, Washington via WSDOT, Oregon via ODOT TripCheck RWIS, Montana via MDT 511, Wyoming via WYDOT 511, Utah via UDOT, New England via Compass C2C). Sensor data on the actual road, distinct from the modeled get_operating_risk. Returns 'no road weather' outside the covered area.
get_season_leaderboard
ChatGPTRank resorts by how a season actually went, scoped to a place. This is the tool for "which <place> resort had the most <metric> last season" — the single most common retrospective question agents ask. Scope by state or province (Maine, Montana, Wyoming, British Columbia, Hokkaido, Nagano, Valais, Tyrol), by country (Switzerland, Japan, Canada), or by region (north-america, europe, asia, oceania, south-america, or a colloquial range: alps, andes, rockies, scandinavia). Metrics: snow_days, total_cm, powder_days, bluebird_days, max_storm (biggest single 24h snowfall, with the date it fell), peak_depth, longest_dry_spell. Covers 30 seasons back to 1996, so it answers historical and multi-season questions too, not just last season. Season accepts 2025, "2025-26", 2026, or "last" and resolves them all to the same season. Backed by ERA5 reanalysis across the full season window, so figures cover the entire season rather than only the days SnowSure has been live. Use get_snow_history for ONE resort's own history, get_monthly_snow for typical month-by-month climatology, and get_snow_report or find_best_powder for conditions RIGHT NOW.
get_season_openings
ChatGPTResorts whose season OPENING DATE is a specific day — answers "what opens today?", "opening this week", or "which resorts start their season on June 27?". Returns only resorts scheduled or confirmed to open on that date, NOT all currently-open resorts. Prefer over get_southern_hemisphere_report for opening-day questions. This tool is date-scoped, so it is the wrong shape for two neighbouring questions: for a RANKED retrospective ("which resorts opened earliest for the 2025-26 season, top 6 by verified opening date"), use get_insights with category=season_calendar; for historical norms ("which resort typically opens earliest each season", "is X usually open by Thanksgiving"), use ask_snowdata.
get_snow_history
ChatGPTGet historical snowfall data for a resort including season totals, comparison to 5-year and 30-year averages, and best months to visit.
get_snow_quality
ChatGPTWhat the surface actually skis like at a resort — Dry powder, Soft, Packed, Crust, Spring, Wet, Wind-affected or No snow — from SnowSure's SLF SNOWPACK simulation at three elevations, with the reason and how confident it is. This is the question snowfall totals cannot answer: 30 cm that fell dry and 30 cm that fell warm and refroze are the same number and a different day. MODELED, not measured, and it describes the surface only — it is not an avalanche assessment (use get_avalanche). Returns 'not available' where the simulation has not been verified for that region yet.
get_snow_report
ChatGPTGet the global snow report with top-ranked resorts by snow conditions. Returns resorts sorted by SnowSure score, forecast, or recent snowfall. Use this for "where has the best snow?" or "top ski resorts right now" queries.
get_southern_hemisphere_report
ChatGPTGet snow conditions for Southern Hemisphere ski resorts (Australia, New Zealand, Argentina, Chile) currently in season. Use for "best snow in Australia/NZ/Argentina" or June–October ski trip queries. Prefers operator-verified data when available.
get_storm_watch
ChatGPTStorm Watch: named multi-day storm systems the models are flagging days ahead, grouped as one event across every resort in the path and ranked biggest first. Use for "is a storm coming", "what's the next big system", "where will it dump this week". Each event carries its window, the forecast total per resort, and a confidence tier (watching / likely / locked). FORECAST, NOT OBSERVATION — nothing here has fallen yet; use get_snow_report or find_best_powder for snow that already has. Returns no events when nothing is being watched, which is the normal state outside a storm cycle.
get_trip_window
ChatGPTHistorical odds for a SPECIFIC trip window at one resort — 'Whistler on March 27', 'Vail Jan 10–17'. From ~30 years of ERA5 monthly history it blends the window's months (weighted by days) into: the snow-day probability (the headline — for a short window how OFTEN it snows beats how MUCH falls in a season), window-scaled expected snowfall and typical base depth, the same window across the last 5 individual seasons, and the best nearby month (±1) by snow-day odds. Window max 31 days; dates are YYYY-MM-DD. This is HISTORY, not a forecast and not a prediction — for the next 14 days use get_weather_forecast, and for a whole-month question use get_monthly_snow. Windows with under 5 tracked seasons return insufficient rather than thin odds.
get_weather_forecast
ChatGPTGet detailed day-by-day weather forecast for a resort including temperature, snowfall, wind, and conditions for each of the next 14 days.
get_webcam_status
ChatGPTGet live webcam information and links for a resort to see current conditions visually.
list_alerts
ChatGPTList the signed-in user's alert subscriptions. Requires a SnowSure user access token (OAuth).
list_insight_categories
ChatGPTList SnowSure insight categories (live conditions, current season, last season, forecast trust, patterns, SnowSure index, ground truth). Use before get_insights to choose a category filter. Lighter than raw leaderboards — retrospective and verification-backed cards.
list_saved_resorts
ChatGPTList the signed-in user's saved resorts. Requires a SnowSure user access token (OAuth); without one it returns an authorization-required error telling the agent how to connect.
plan_ski_road_trip
ChatGPTPlan a multi-stop ski road trip: picks the top-scoring resorts in a region, orders them into a drivable route (nearest-neighbour, minimal backtracking), allocates your days across stops, estimates each driving leg, and folds in live conditions plus chain-control where covered. Args: region (required), days, optional pass.
plan_ski_trip
ChatGPTGet ski trip recommendations based on dates, preferences, and conditions. Suggests best resorts for a given time period.
remove_saved_resort
ChatGPTRemove a resort from the signed-in user's saved list. Requires a SnowSure user access token (OAuth).
save_resort
ChatGPTAdd a resort to the signed-in user's My Mountains, the list of resorts they follow. Requires a SnowSure user access token (OAuth). The slug must be a real SnowSure resort.
search_resorts
ChatGPTSearch for ski resorts by name, country, or region. Returns matching resorts with basic conditions. Use for "find resorts in [location]" or "search [name]" queries.
subscribe_alerts
ChatGPTSubscribe the signed-in user to snow alerts. Requires a SnowSure user access token (OAuth). type: 'powder' (OBSERVED fresh snow >= thresholdCm in 24h), 'forecast' (the forecast total over windowDays clears thresholdCm — 14 days with Pro or on a resort in My Mountains, 7 otherwise), 'trip' (a Powder Trip — a storm inside 14 days with a curated stay to book — at a resort you name, or on a pass via scope 'pass:ikon-pass' / 'pass:epic-pass' / 'pass:mountain-collective'; scope 'any' is not accepted for trips), 'opening' (resort opens for the season), or 'bluebird' (powder day then clear skies).
unsubscribe_alerts
ChatGPTRemove one of the signed-in user's alert subscriptions by id (from list_alerts). Requires a SnowSure user access token (OAuth).
