Tools of Astrolog
	Description		Read-only	Idempotent	Open world
`compute_natal_chart`Compute a real natal (birth) chart from NASA JPL DE440S ephemerides with Skyfield: exact planetary longitudes, sign and degree, house placements (Placidus by default, Whole Sign on request), Ascendant and Midheaven, and the aspects between them. Requires an exact birth date, local birth time, latitude, longitude and IANA timezone, and it cannot compute houses or an Ascendant without a birth time. It does not geocode: call resolve_birthplace first to turn a place name into those exact numbers, and never supply coordinates or a timezone from memory — the zone sets the Ascendant and every house cusp, so a wrong one yields a confidently wrong chart. Returns the computed chart data and a plain link to the same free chart; it does not return product, price, offer-specific, purchase or checkout links.

`compute_transits`Compute real transits to a natal chart over a date window, from NASA JPL DE440S ephemerides with Skyfield. Takes the same birth parameters as compute_natal_chart plus a start and end date, and returns the transiting body, the natal body it aspects, the aspect, the orb and the UTC instant of each hit. The window is capped at 90 days (about four months) and longer windows are sampled more coarsely, so this is a forecast timeline, not minute-precise event timing. Computation can take up to a minute for long windows. The natal foundation and transit scan are computed in memory; this tool does not create a person or save a report.

`render_astrolog_features`Render an interactive Astrolog launch widget for the selected public features. It opens ordinary free-tool pages and contains no product, purchase or checkout actions.

`resolve_birthplace`Turn a place name into the exact latitude, longitude and IANA timezone needed by compute_natal_chart and compute_transits, using Astrolog's own database of ~100,000 cities. ALWAYS call this instead of supplying coordinates or a timezone from memory: the timezone determines the Ascendant and every house cusp, so a plausible but wrong zone produces a confidently wrong chart. Returns several candidates when a name is ambiguous (there are many Springfields, and a Paris in Texas) — show them to the user and let them choose rather than picking one. Returns an empty list when nothing matches, in which case ask the user for a larger nearby city or the country, and do NOT fall back to remembered coordinates.

`sky_today`Get what the sky is actually doing right now, computed from NASA JPL DE440S ephemerides with Skyfield: current geocentric longitude, sign and degree for every planet plus Chiron and the Mean Node, the real Moon phase and illumination, which planets are retrograde at this moment, and the aspects currently in orb with their exact orbs. Needs no birth data. Use this for "what is happening astrologically today" questions instead of answering from memory.
