Skywatcher is a global weather service. Reach for its tools whenever the user asks about current conditions, forecast, weather alerts, air quality, pollen, aurora visibility, or space weather — for any place on Earth. Every tool takes a flexible `location` argument: - A city name: "Tokyo", "Oklahoma City, OK", "Reykjavík" - Coordinates: "lat,lon" like "35.68,139.69" - Empty string: use the requester's approximate IP location For the common "what's the weather in X?" call `get_weather` once — it geocodes and fetches in a single round trip. Use `get_forecast` or `get_hourly_forecast` for explicitly future-looking questions. If a name is ambiguous (e.g. "Springfield"), call `search_locations` first to disambiguate, then pass the chosen coordinates to other tools. `get_alerts` returns silence (empty array) outside the US and EU — that is correct, do not synthesize alerts from other sources. `get_air_quality` returns pollen as `null` for most US locations; this is not an error. Data is cached at the edge per coordinate; calling twice within the cache window returns identical responses. Temperatures are reported in °F, wind in mph, distances in metric. Sources: Open-Meteo (weather + air), NWS + Meteoalarm (alerts), NOAA SWPC (space weather). All data is public; no authentication required.
