## Tools (3)

- `find_moon_phase`: Use this when the user asks what the moon looked like on a date (birthday, wedding, first date), the moon phase today or tonight, whether two people's birthday moons complete each other ("our moons make a full moon"), or wants a moon phase calendar for a month. Returns phase name, illumination %, moon age, waxing/waning, exact phase times and the next full and new moon, computed with astronomical algorithms. Does not give astrology readings, tides or moonrise times. Do not use for planets or eclipses.
- `generate_moon_poster`: Use this when the user wants a printable moon phase poster: the moon on one special date, two dates side by side ("our moons" couple print), or a lunar calendar of a whole year. Computes the real phases and returns a preview plus vector PDFs (12x18 in, 18x24 in, A3, Letter, A4) and SVG. Does not sell or ship prints. Do not use for a quick phase answer without a poster; that is find_moon_phase.
- `generate_star_map`: Use this when the user wants a star map or night sky poster for a date and place: the sky over a city on a birthday, wedding, anniversary or the night they met, or the sky tonight. Computes the real positions of about 2,900 stars, constellation lines and the Moon for the city's local time (time zones and DST handled) and returns a preview plus vector poster PDFs (12x18 in, 18x24 in, A3, Letter, A4) and SVG. Takes a city name, not coordinates. Does not draw planets and is not for navigation or telescope pointing.
