compare_vitamin_d_year

Returns each place's months with sun, exact season span and viable days per year, plus rankedByViableDays. Use this instead of calling get_vitamin_d_year once per city: only this tool can draw the years on a shared axis.

Use this when those values are unknown, when the user wants to change them, or instead of asking for them one at a time in conversation. Whatever the user picks comes back into the conversation; pass those values explicitly to the other tools afterwards.
estimate_sun_session
agelat*lon*dateminutes*skinType

Takes a start time (defaults to the day's best hour) and session minutes; returns estimated IU (with the physiological cap), average UV and clear-sky minutes-to-sunburn. Use for any 'how much did I get / can I get in X minutes' or 'how long without burning' question.
get_current_status

The signed-in user's current city and favorite cities with coordinates and timezones, ready to feed into the public tools. Requires OAuth (scope profile:read).

Covers the calendar days f… The signed-in user's sun history from the app's calendar: which recent days had viable sun, which they confirmed going outside, and their current streak. Covers the calendar days from `from` to `to`; records exist only for days the app was open, so a date missing from `records` means nothing was measured, not that the sun was insufficient. Requires OAuth (scope history:read). Renders as a calendar the user can tap to confirm a day.
get_my_profile

Call this FIRST for any personal question, then pass its values to the public tools instead of asking the user.
get_sun_forecast

Use this for any question spanning several days — 'which day this week should I go out', 'will it be better tomorrow', 'when's my next chance' — instead of calling get_vitamin_d_window once per date.
get_sun_times
lat*lon*datetimezone
Sunrise, sunset, solar noon, civil dawn/dusk, morning AND evening golden hour, and day length (with day-over-day trend) for a location and date.

Handles midnight sun and polar night. Pure sun times — for vitamin D questions use the vitamin_d tools instead.
get_vitamin_d_window
agelat*lon*dateatTimeskinType
+4
The solar vitamin D synthesis window for ONE specific day at a location, for a personal profile: when UV is strong enough (index ≥ 3), the best hour, the clear-sky minutes needed t… The solar vitamin D synthesis window for ONE specific day at a location, for a personal profile: when UV is strong enough (index ≥ 3), the best hour, the clear-sky minutes needed to reach the target IU, and (with atTime) the minutes at the specific hour the user plans to go out. Returns synthesisPossible=false when the sun never gets high enough that day. Only for single-day questions — for months, seasons or 'when during the year', call get_vitamin_d_year instead of calling this once per date.
get_vitamin_d_year

Use this for any question about months, seasons, winter/summer or 'when during the year can I…' — never probe individual dates with get_vitamin_d_window for that.

Three values: confirmed=true (went out, the default), confirmed=false (had usable sun but stayed in), confirmed=null (clear the answer). Defaults to today. Requires OAuth (scope history:write).

Use it when the user corrects a stretch — get_my_history marks inherited days with `locationAssumed`, and the history calendar offers those stretches for correction. Pass a cityId from search_city, or lat/lon. Changes only the location: whether they went outside that day is untouched. Requires OAuth (scope history:write).
