Tools

• ask_snowdata

  Text-only Q&A grounded in SnowSure data (~1s). Use for open-ended questions, terrain %, expert-run counts, advice, AND specifically: El Niño / ENSO / 2026-27 winter outlook (or call get_elnino_signal / get_elnino_rankings), head-to-head resort comparisons (annual snowfall, vertical drop, base/summit elevation, skiable area — "which has more snowfall, Niseko or Whistler"), season-opening norms ("which resort typically opens earliest", "usually open by Thanksgiving"), glacier / year-round skiing, and factual resort & geography trivia (what country/state/island a resort is in, named runs like Corbet's Couloir, records like the highest chairlift). NEVER use for photo/gallery/picture requests (→ get_resort_photos) or resort guide cards (→ get_resort_info). Does NOT render UI cards.

  shallow
• book_lodging

  Lodging 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.

  shallow
• compare_forecasts

  Compare 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.

  shallow
• compare_passes

  Compare 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.

  shallow
• compare_resorts

  Compare 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.

  shallow
• find_best_powder

  Find 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.

  shallow
• find_flights_to_powder

  Complete 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).

  shallow
• find_pass_resorts

  List 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.

  shallow
• find_powder_trips

  Powder 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 | family | budget) shows only hotels handpicked into that tier. Each hotel carries an attribution-tagged booking link; booking completes on LUXSKI.

  shallow
• find_resorts_by_criteria

  Find resorts matching specific criteria like minimum snow depth, elevation range, number of runs, or SnowSure rating. Advanced filtering for trip planning.

  shallow
• get_avalanche

  Current 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.

  shallow
• get_destination

  Multi-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).

  shallow
• get_elnino_rankings

  Ranked 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'.

  shallow
• get_elnino_signal

  Resort-level El Niño / ENSO outlook from SnowSure's 30-year fleet dataset (152 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. Tilt, not fate — n=3 disclosed; D/E tiers are timing plays.

  shallow
• get_insights

  Get categorized SnowSure intelligence insights (not just snow totals). The last_season category is the one to reach for on retrospective questions — how a finished season compared to its 5yr norm, who led it, where the models were trustworthy. Also covers model accuracy by region, longest dry spell, and trend pulse. Insights are hemisphere-scoped narrative cards; when the question names a specific state, province, country or region and wants a ranked list, use get_season_leaderboard instead. Filter by category or insightType=intelligence to skip simple leaderboards.

  shallow
• get_ml_trends

  Fetch 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, ML extended outlook (days 8–14), global forecast trust, and powder/bluebird event logs. Start with dataset=catalog. Its leaderboards read CURRENT-season counters and are global — they take no season and no country/state filter. For a past season, or for any ranking scoped to a state, province, country or region ("most snow days in Maine last season", "rank BC resorts by season snowfall"), use get_season_leaderboard instead. Prefer get_insights for narrative intelligence cards; use this for raw rankings and time series.

  shallow
• get_monthly_snow

  Typical 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.

  shallow
• get_my_snow_report

  Personalized 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).

  shallow
• get_operating_risk

  Will 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.

  shallow
• get_pass

  Details for a multi-resort ski pass (Epic, Ikon, Mountain Collective, …): operator, season pricing tiers, destination count, regions, and the buy link.

  shallow
• get_powder_reels

  Powder 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.

  shallow
• get_regional_summary

  Get a summary of snow conditions across an entire region or country with statistics and top resorts.

  shallow
• get_resort

  Single-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, base depth, forecast). card=full → detailed markdown only, no card. "Resort guide" → card=guide. "Photos/gallery" → card=photos. "Conditions/forecast" / "is it open right now, base depth, lifts open of total" → card=snow (open status, base depth, and lifts open of total). Prefer get_resort_info / get_resort_photos when available (same cards).

  shallow
• get_resort_info

  INTERACTIVE 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). Answers single-resort stat questions: base/summit elevation, vertical drop, skiable area, average annual snowfall. Examples: "Aspen Mountain resort guide", "how many lifts at Jackson Hole", "what is the base elevation at Arapahoe Basin". For X-vs-Y stat questions use compare_resorts. Do NOT use get_resort (that shows the snow conditions card).

  shallow
• get_resort_photos

  INTERACTIVE 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.

  shallow
• get_road_access

  Driving access for a resort — answers "do I need chains to get to <resort>" and "is the road to <resort> open": chain-control / mountain-pass / road-surface conditions on nearby highways (California via Caltrans, Washington via WSDOT, Colorado via CDOT, Utah via UDOT). Returns 'no road data' outside the covered area. Links to the official DOT map; the resort's road status is authoritative.

  shallow
• get_road_cameras

  Live 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, Utah via UDOT). Distinct from resort webcams. Returns 'no road cameras' outside the covered area; each camera includes a live image URL.

  shallow
• get_road_weather

  Measured roadside weather (RWIS) on the highways near a resort — surface + air temperature, visibility, wind, precipitation (Colorado via CDOT, Washington via WSDOT, Utah via UDOT). Sensor data on the actual road, distinct from the modeled get_operating_risk. Returns 'no road weather' outside the covered area.

  shallow
• get_season_leaderboard

  Rank 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.

  shallow
• get_season_openings

  Resorts 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.

  shallow
• get_snow_history

  One resort's own snowfall history: season totals, comparison to its 5-year and 30-year averages, and best months to visit. Scoped to a SINGLE resort — for "which resort in <state/country/region> led <metric> last season", use get_season_leaderboard instead.

  shallow
• get_snow_report

  Get 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.

  shallow
• get_southern_hemisphere_report

  Get snow conditions for Southern Hemisphere ski resorts (Australia, New Zealand, Argentina, Chile) currently in season. Answers "is Perisher / Portillo / Valle Nevado open right now and what are the current conditions", "is the Australian ski season underway", and "which Southern Hemisphere region — the Andes, Australia, or NZ — has the best snow right now". Use for June–October SH ski queries. Prefers operator-verified data when available. Do NOT use for a specific opening DATE — use get_season_openings instead. Note that the SH is not the only place to ski in the northern summer: a handful of NH glaciers run summer or year-round operations (Zermatt/Matterhorn Ski Paradise skis all year; Passo dello Stelvio, Stryn and Galdhøpiggen run deep into autumn; Hintertux, Saas-Fee, Tignes, Les Deux Alpes and Timberline have dated summer windows that close). For those, call get_resort on the named glacier — summer windows are tracked per resort and a glacier being famous for summer skiing does not mean it is open today.

  shallow
• get_weather_forecast

  Get detailed day-by-day weather forecast for a resort including temperature, snowfall, wind, and conditions for each of the next 14 days.

  shallow
• get_webcam_status

  Get live webcam links and status for a resort to see current on-mountain conditions visually — answers "show me the webcam / live cam at <resort>", "current conditions on camera", and named-cam lookups.

  shallow
• list_alerts

  List the signed-in user's alert subscriptions. Requires a SnowSure user access token (OAuth).

  shallow
• list_insight_categories

  List 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.

  shallow
• list_saved_resorts

  List 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.

  shallow
• plan_ski_road_trip

  Plan 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.

  shallow
• plan_ski_trip

  Get ski trip recommendations based on dates, preferences, and conditions. Suggests best resorts for a given time period.

  shallow
• remove_saved_resort

  Remove a resort from the signed-in user's saved list. Requires a SnowSure user access token (OAuth).

  shallow
• save_resort

  Save a resort to the signed-in user's favorites. Requires a SnowSure user access token (OAuth). The slug must be a real SnowSure resort.

  shallow
• search_resorts

  Search for ski resorts by name, country, or region. Returns matching resorts with basic conditions. Use for "find resorts in [location]" or "search [name]" queries.

  shallow
• subscribe_alerts

  Subscribe the signed-in user to snow alerts. Requires a SnowSure user access token (OAuth). type: 'powder' (OBSERVED fresh snow >= thresholdCm in 24h), 'forecast' (the 14-day FORECAST clears thresholdCm within windowDays — the proactive 'tell me when a powder trip is forming' watcher), 'opening' (resort opens for the season), or 'bluebird' (powder day then clear skies).

  shallow
• unsubscribe_alerts

  Remove one of the signed-in user's alert subscriptions by id (from list_alerts). Requires a SnowSure user access token (OAuth).
