find_stationSearch the ~17,000-station GuzzStations catalog by name, country, or coordinates. Optional `compact=True` returns just the newest TMYx per station (6–10× smaller responses for chained agent workflows).analyze_weatherStatistical summary of an EPW. Three modes: `url=` (single file), `urls=[]` (2–10 file comparison), `config={...}` (synthesize a morphed scenario from lat/lon — no EPW content returned). Optional `include_full_ashrae`, `include_improbability`, `include_idf`.chart_weatherInline SVG chart. Single-EPW types: `diurnal`, `temp_carpet`, `wind_rose`, `monthly_boxplot`, `utci_carpet`, `economizer_carpet`, `pv_tilt_azimuth`, `solar_under_events`. Multi-EPW type: `comparison`.generate_weather_fileGenerate and return a downloadable weather file with the full morph stack. Format = `epw` / `ddy` / `csv` / `zip` / `pvsyst`. Supports `ensemble=true` (all SSPs at once).
