## Tools (6)

- `bazi_chart`: Calculate a BaZi / Four Pillars of Destiny chart from a birth date, optional birth time and the birthplace time zone. Uses solar-term boundaries (the year changes at the Start of Spring, Li Chun) via an astronomical calendar engine. Returns the four pillars with Ten Gods, the Day Master, five-element balance, luck pillars and the coming years.
- `cast_i_ching`: Cast an I Ching reading with the traditional three-coin method (six tosses, bottom line first). Returns the primary hexagram, any changing lines and the relating (transformed) hexagram, with links to each hexagram's meaning. Use this instead of making up a hexagram.
- `chinese_zodiac`: Find a person's Chinese zodiac animal from a birth year or date (handles the Lunar New Year and Start of Spring boundaries for January–February births) and return the 2027 Year of the Fire Goat forecast for that sign: love, career, money and a tip.
- `draw_tarot_cards`: Draw tarot cards at random from a full 78-card Rider–Waite–Smith deck (cryptographically random, no repeats). Returns each card with its position, upright/reversed orientation, keywords and a link to its full meaning. Use this instead of inventing cards when a user asks for a tarot reading.
- `get_hexagram`: Look up one of the 64 I Ching hexagrams by number (1–64), English name ("The Wanderer"), Chinese character (旅), Japanese name (火山旅) or pinyin (ambiguous pinyin like "lu" returns the candidates). Returns its essence, judgment, image, love and career readings, guidance and the six line texts.
- `get_tarot_card_meaning`: Look up the meaning of a tarot card: keywords, upright and reversed meaning, love, feelings, career and money readings, and whether it leans yes or no. Accepts names like "The Tower", "3 of Cups", "Queen of Swords" or "ace of coins".
