    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    Description, as the server wrote it
    Creates a festive Christmas card (text plus SVG image) about someone, from their birth date and optional first name: sun sign and life path number, described as character, not prediction. The card text talks about the recipient in the third person (by name, or neutrally without a name). No personal data stored.

    • The name "compare_charts" says "compare": a word for reading.
    Description, as the server wrote it
    Compares two birth charts (synastry): the closest aspects between person A's and person B's planets, with orbs and a short, balanced summary. Birth times and places are optional. Instead of person_b you can pass `celebrity` (name or X handle, see list_celebrities) for a playful star match with a score and a share text for X. No predictions, nothing stored.

    • The name "get_birth_chart" says "get": a word for reading.
    Description, as the server wrote it
    Computes a real birth chart from astronomical positions (tropical zodiac): Sun to Pluto with sign, degree and retrograde flag, major aspects with orbs, and a short character-focused interpretation. Ascendant, Midheaven and Whole Sign houses only when birth time and place are both given. Without a time the Moon is flagged as approximate. No predictions, nothing stored.

    Description, as the server wrote it

    • The name "get_transits" says "get": a word for reading.
    Description, as the server wrote it
    Shows where the planets are now (or on a given UTC date) and which major transits they make to a person's birth chart, with orbs and exact dates, for one day or a 7-day week. Short reflective interpretation, no predictions, nothing stored.

    • The name "list_celebrities" says "list": a word for reading.
    Description, as the server wrote it
    Lists the famous people you can compare charts with in compare_charts (about 1000 most-followed real people on X, birth dates from Wikidata cross-checked with Grokipedia). Optional search query (name, handle or description such as 'singer'); returns up to 25, most followed first. Most are date-only.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
