## Tools (as reported by the server, not verified)

- `get\_stargazing\_conditions`: Score the next nights for stargazing at a location \(0-100 per night\). Use for "when should I stargaze this week near X", "is Saturday any good for the Milky Way", trip planning. Each night combines the three-layer cloud-cover forecast, moon illumination and up-fraction, and the astronomical-darkness
- `get\_tonight\_agenda`: Get tonight's stargazing plan for a location: score, darkness window, and what to observe. Use when the user asks "what can I see tonight" / "is tonight worth going out". Returns tonight's sky score and darkness window plus a ranked agenda of observing targets appropriate for the location's sky dark
- `find\_dark\_sky\_sites`: Recommend dark-sky sites near a location, ranked by whether the drive is worth it. Use for "where should I drive to stargaze near X". Sites are grouped by drivability \(how far\), then ranked by a drive-worth score combining the best weather window over the next 7 nights, how much darker the site is t
- `get\_aurora\_forecast`: Get the aurora \(northern/southern lights\) outlook for a location. Use for "any chance of aurora tonight near X". Combines the Kp-index forecast with the location's geomagnetic latitude to say whether aurora could be visible there, and when. Args: lat: Latitude in decimal degrees \(-90..90\). lon: Long
- `get\_light\_pollution`: Estimate light pollution at any point: approximate Bortle class and what's visible there. Use for "how dark is the sky at X" / "can I see the Milky Way from X". Returns the zenith-brightness-derived estimate \(mpsas, approximate Bortle class\) and a plain-language ceiling: what the Milky Way, naked-ey
