    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Provide authentic, deterministic astrological framework guidance for any life question (e.g. career shift, relationship milestones, financial timing, health/somatic wellness, relocation). Corresponds to the /ask slash command in Discord and Google Chat. Explains which astrological houses, ruling planetary significators (Karakas), and timing triggers govern the user's inquiry, with a direct CTA to explore the full chart on ERUX.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Calculate a deterministic personal natal chart or national mundane chart using the high-precision astronomical ephemeris calculation engine. Corresponds to /chart and /mundane slash commands. Supports EITHER a country name (e.g. 'India', 'USA', 'France') for a national chart OR personal birth details ('date', 'time', 'city'). Automatically provides dynamic 'chart_ui_url', calculates planetary placements, active Dasha cycle, grounded knowledge-base insights, and an ERUX interactive UI link. CRITICAL FOR AI: When calculate_chart is called, present the key placements cleanly and provide a direct, prominent link inviting the user to view their interactive chart wheel on ERUX using 'chart_ui_url' (e.g. [✨ Open Your Interactive Chart Wheel on ERUX](chart_ui_url)).

    Description, as the server wrote it
    Calculate the classical Parashara Vimshottari Dasha planetary timeline (120-year cycle) for a person or founding event. Corresponds to the /dasha slash command. Requires birth date ('date', YYYY-MM-DD), birth time ('time', HH:MM, default '12:00'), and birth city ('city'). Returns current Mahadasha and Antardasha periods, active dates, psychological and karmic significance, upcoming macro-epochs, and a direct link to the interactive ERUX Dasha calendar.

      annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "get_horoscope" says "get": a word for reading.

      What this check looks for
    Description, as the server wrote it
    Generate a personalized transit horoscope, real-world strategic forecast, and exact astronomical time-windows for a user based on their natal placements and active planetary transits. Corresponds to /horoscope and /daily commands. Supports cadences: 'daily' (today's transits and hourly Horas), 'weekly' (7-day Monday–Sunday transit arc), 'monthly' (30-day sign ingresses & lunations), and 'yearly' (12-month Solar Return to Solar Return Varshaphala journey). MANDATORY PARAMETERS: The user's natal birth date ('birth_date', YYYY-MM-DD) and natal birth city ('birth_city') are strictly required. NEVER pass today's date into 'birth_date' — today's transit date is calculated automatically by the server based on location coordinates. If the user asks for a future or target date (e.g. next week or 2027), pass that date into 'target_date', NOT 'birth_date'. Optionally accepts 'current_city' if the user has relocated, 'cadence' ('daily', 'weekly', 'monthly', 'yearly'), and 'user_prompt' containing the user's raw inquiry. For daily cadence, returns 'astronomical_time_windows' (exact topocentric sunrise/sunset, 24 planetary Horas, Rahu Kaal, Abhijit Muhurta, Brahma Muhurta) and 'panchang_timing' (exact Nakshatra and Tithi transitions). CRITICAL FOR AI: When suggesting times of day, you MUST quote the exact astronomical_time_windows provided. Never invent arbitrary hours.

    Get deep personalized astrological interpretation for canonical life pillars or placements (e.g. 'career_and_vocation', 'relationships', 'dasha_analysis', 'wealth_and_finance', 'health_and_vitality').

    Description, as the server wrote it
    Identify auspicious & powerful classical Vedic Yogas present in a birth or mundane chart (e.g. Raja Yogas, Dhana Yogas, Pancha Mahapurusha Yogas, Gaja Kesari, Budhaditya). Corresponds to the /yogas slash command in Discord and Google Chat. Requires birth details ('date', 'time', 'city') or country name ('country'). Returns active yogas, classical definitions, and link to ERUX divisional varga breakdown.

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.
