What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of astromatlog.com controls every word below.

get_natal_chart

Compute text-only natal placement facts. Use get_natal_chart_image instead for broad chart readings, visual requests, or /chart. Call with no arguments for the logged-in user. Pass relation_id alone for a tracked person; both subjects' stored birth data are authoritative.

get_current_sky

Return current planetary positions plus active retrogrades, upcoming sign transitions, and the next solar/lunar eclipse dates.

get_transits

Return upcoming planetary transits, retrogrades, and eclipses for the next N days.

get_natal_chart_image

Render an inline visual astrology chart/card as a base64 PNG. Use this when the user explicitly asks for a chart/card/image/visual/wheel, '/chart', placement overview, Big 3, rising, or ascendant. Do not call it for ordinary topic or timing questions unless the user asks for a chart visual. Call with no arguments for the logged-in user's natal card; use visual_mode='card' for first charts, visual_mode='transit_card' with include_transits=true only for explicit today/current chart requests, 'wheel' for a clean wheel, or 'detailed' for technical users. Pass relation_id alone for a tracked person's chart. Only pass manual birth data with use_logged_in_user=false for an untracked person.

get_compatibility

Synastry analysis between two charts. Person A defaults to authenticated user; pass person_b_date plus person_b_lat / person_b_lon (resolve city names client-side via city_search), or pass relation_id for someone the user already tracks.

get_compatibility_chart_image

Render a synastry/compatibility bi-wheel chart as a base64 PNG. Use this for visual compatibility requests such as 'compatibility chart for my son and me'. Person A defaults to the authenticated user. Pass relation_id alone for someone the user already tracks; the person_b_* fields are for anyone else.

chat

Send a message to your personal AI astrologer. Returns structured {blocks, chart_image?, metadata} payload.

get_chat_start

Return the welcome message and command suggestions for the chat UI.

get_horoscope

Return today's personalized horoscope for the authenticated AstroMatLog account. This tool takes no arguments: the user's birth date, birth time, birthplace, and chart data are already stored. Never ask for zodiac sign or birth data before calling. If no horoscope exists yet, this tool generates one from the account's stored birth data. If generation is temporarily unavailable, report that directly; do not ask for a sign or birth date.

regenerate_horoscope

Force regeneration of today's horoscope via the LLM. Subscription required.

convert_utc_to_julian_day

Convert an ISO 8601 UTC datetime to Julian Day UT. Defaults to now if omitted.

convert_julian_day_to_utc

Convert Julian Day UT to a UTC datetime.

get_ephemeris_planet_position

Compute one planet's geocentric ecliptic position at a UTC datetime.

get_ephemeris_planet_positions

Compute geocentric ecliptic positions for selected planets.

get_ephemeris_moon_phase

Compute Moon phase, elongation, Moon sign, and waxing/waning trend.

get_ephemeris_house_cusps

Compute Placidus house cusps plus ascendant and midheaven.

get_ephemeris_house_for_longitude

Return the house number containing an ecliptic longitude.

get_ephemeris_aspect_between

Calculate angular separation and recognized major aspect between two longitudes.

get_ephemeris_aspects

Find major aspects among selected planetary positions.

get_ephemeris_retrogrades

Return active and upcoming retrogrades.

get_ephemeris_sign_transitions

Return planetary sign transitions.

get_ephemeris_eclipses

Return the next solar and lunar eclipses.
