kerykeion

Use Kerykeion (the Python astrology library) to compute and visualize charts. Trigger this skill whenever the task involves astrology, birth/natal charts, horoscopes, zodiac signs, planetary positions, houses, aspects, synastry/compatibility, composite charts, transits, solar/lunar returns, ephemeris tables, the Moon phase, sidereal/Vedic ayanamsa, or generating SVG chart images — and whenever someone wants astrological data turned into an LLM-ready context or a text report. Use it even if the user never says "Kerykeion": any request to build a birth chart from a date/time/place, score relationship compatibility, track transits over a date range, or render a zodiac wheel should go through this skill so the code uses the real, current API instead of guessed method names.
