## Tools (10)

- `check_age_compatibility`: Compares two people by birth year and gender using Vietnamese age-matching (nạp âm element, heavenly stem, earthly branch, Bát Trạch cung phi, zodiac animal) and returns a score out of 100 with each factor explained.
- `convert_lunar_solar`: Converts a date between the Gregorian calendar and the Vietnamese lunar calendar (with leap months, 1900–2100), and gives the can chi of the day, month and year plus the solar term.
- `create_tuvi_chart`: Builds a Vietnamese Tử Vi Đẩu Số (Purple Star) birth chart from Gregorian birth date, birth time and gender: lunar date, can chi, nạp âm, cục, the 12 palaces with their stars, and a short rule-based reading of each palace. Use when the user wants their Tử Vi chart or asks what their chart says.

Returns the best days with reasons and good hours, and the days to avoid.
- `get_2027_forecast_by_birth_year`: Returns the traditional facts for a birth year in the lunar year 2027 (Đinh Mùi): age, relation of the birth branch and stem with the year, element relation, Tam Tai, Kim Lâu, and the yearly palace for men and women.
