Text-only Q&A grounded in SnowSure data (~1s). Use for open-ended questions, terrain %, expert-run counts, advice, AND specifically: 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.

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.

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). Examples: "Aspen Mountain resort guide", "how many lifts at Jackson Hole". Do NOT use get_resort (that shows the snow conditions card).

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.

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).

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.

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.

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.

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.

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

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

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" 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.

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. For historical-norm questions ("which resort typically opens earliest each season", "is X usually open by Thanksgiving / mid-December"), use ask_snowdata instead — those are about typical timing, not a specific calendar date.

Get historical snowfall data for a resort including season totals, comparison to 5-year and 30-year averages, and best months to visit.

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

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

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

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.

Get 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.

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. Prefer get_insights for narrative intelligence cards; use this for raw rankings and time series.

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).

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.

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.

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

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).

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

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

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.

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

List the resorts on a ski pass, optionally filtered to a region. Returns names + SnowSure slugs you can pass to get_resort.

Compare ski passes on price, resort coverage, and value. Optionally pass resortSlugs you plan to ski and tripDays to see which pass covers them and whether it beats buying window lift tickets.

Compare 2–4 resorts side by side across snow, terrain, and live conditions — every value comes from the SnowSure conditions resolver/contract. Optionally restrict to specific dimensions.

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).

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.

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.

Driving access for a resort — 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.

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.

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.

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.

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).
