A4.1/5.0

Scored across 15 tools

Disambiguation3/5

There are several overlapping clusters: dasha/timing tools (explain_dasha, life_timeline, my_family_phases), birth-chart summaries (free_kundli, my_kundli, full_chart), and compatibility tools (kundli_milan, match_my_profiles). Descriptions clarify input-source differences (typed birth details vs saved profile), but an agent still has to carefully distinguish purpose, especially for phase and timing questions.

Naming Consistency3/5

Naming is mixed: some tools use verb_noun (compare_family, explain_dasha, search_place), some use adjective_noun (free_kundli, full_chart), some are noun_verb (kundli_milan), and several use a my_ prefix. The naming remains readable, but there is no single predictable convention across the set.

Tool Count5/5

Fifteen tools sit comfortably within a well-scoped range for an astrology server that covers chart reading, compatibility, timing, transits, place lookup, learning, and family comparison. The count is large enough to support the domain without becoming unwieldy.

Completeness4/5

The surface covers core Vedic astrology workflows: birth-chart summaries and full charts, compatibility, dasha timing, transits, place search, learning, and yoga rarity. A notable gap is profile lifecycle management: saved profiles can be listed and read, but there is no create, update, or delete tool for saved people.

compare_familyCompare family members' strengths side by sideA
Read-onlyIdempotent
Inspect

Side-by-side view of up to 6 saved people: for each of the 12 life areas (career, money, marriage, health, children ...) whether it is strong, mixed or needs care for each person (Sarvashtakavarga points), and the life chapter and phase each is in now. Use when the user asks how family members differ, who is better placed for something, or wants an overview of the family. Omit profiles to compare the 6 most recently saved. Read-only. Only for people saved on the user's AstroCalc account (needs a free AstroCalc sign-in); birth details typed in the chat work without sign-in in free_kundli, kundli_milan, explain_dasha, full_chart and life_timeline.

Inputs: lang, profiles.

explain_dashaWhat life phase (dasha) someone is in and what changes nextA
Read-onlyIdempotent
Inspect

Explains the life phase a person is in right now, what it tends to bring, when it ends and what comes next, from their birth details; or, without birth details, what a given phase means in general and how long it lasts. Useful when the user wonders why life feels a certain way at the moment, when things will change, or about timing for career, marriage, a move or a fresh start, for themselves or someone close to them. Also for direct questions: "what's my dasha", "which mahadasha am I in", "what's coming in my dasha", "meri dasha kaunsi chal rahi hai", "Shani ki mahadasha kab khatam hogi", "mera time kab badlega". Uses the Vimshottari dasha system. Two ways to call it: (1) with birth details (date, time, place) it returns the running Mahadasha and Antardasha with exact start/end dates, what the period is about for that chart and the next antardashas (AstroCalc engine); or (2) with lord (and optionally antardasha) set to a planet, e.g. lord "Saturn", antardasha "Venus", it returns the general meaning and length of that period, with no birth data needed. Birth details are not stored. Traditional information, not a prediction.

Inputs: lat, lon, date, lang, +4 more.

free_kundliKundli (birth chart) from birth details, read in plain wordsA
Read-onlyIdempotent
Inspect

Reads a person's birth chart from their date, time and place of birth: their core nature, the life phase they are in now and when it changes, the standout strengths in the chart, and which life areas look strong or need care, with what helps. Useful when the user talks about themselves, a family member or someone they know and wants to understand them better: personality, a life change, career or marriage timing, feeling stuck, or what to work on. Also for direct requests in English, Hindi or Hinglish: "make my kundli", "kundli for my birth details", "what is my rashi / lagna / nakshatra", "meri kundli banao", "janam kundali dikhao", "mera lagna kya hai". Calculated by AstroCalc's ephemeris engine (sidereal zodiac, Lahiri ayanamsa). Returns Lagna (ascendant), Moon sign (rashi), Sun sign, nakshatra and pada, the running Vimshottari Mahadasha and Antardasha with dates, the most notable yoga with how rare it is ("1 in N charts"), life areas that are strong or need care, a caveat, and a link to the full free report. Birth details are used only to compute the chart in memory and are not stored. Results are traditional astrology information, not predictions or professional advice.

Inputs: date (required), lat, lon, lang, +2 more.

full_chartFull birth chart in detail (degrees, divisional charts)A
Read-onlyIdempotent
Inspect

The complete birth chart for a detailed reading: Lagna degree; for each planet its sign, degree, nakshatra and pada, nakshatra lord, house, dignity, retrograde status, aspected houses and conjunctions; the 12 houses with lords and occupants; and divisional charts (D9 Navamsa and D10 Dasamsa by default, or any of D2, D3, D4, D7, D9, D10, D12, D16, D20, D24, D27, D30, D40, D45, D60) with vargottama planets. From birth details (free, no sign-in) or for a person saved on the user's AstroCalc account (profile; that needs a free sign-in). Use when a question needs more than the free_kundli summary: a deeper look at career, marriage (7th house, D9), a specific planet or house. AstroCalc calculates; the assistant interprets. Read-only.

Inputs: lat, lon, date, lang, +4 more.

kundli_milanKundli milan: how well two people match for marriage (36 gunas)A
Read-onlyIdempotent
Inspect

Checks how well two people match for marriage in the Indian (Vedic) tradition, from both people's birth details: a score out of 36 with what each of its eight parts means, and whether either person has the Mars placement (Manglik) that families often ask about. Useful when the user is thinking about marriage or a relationship, weighing a proposal or a rishta, or their family has asked for a kundli match: "match my kundli with hers", "kundli milan", "guna milan", "how many gunas match", "kundli milao", "kitne gun milte hain", "rishta aaya hai, kundli match karo", Manglik, Nadi or Bhakoot dosha. Computed by AstroCalc's engine. Returns the Ashtakoota total and band, all 8 kootas (Varna, Vashya, Tara, Yoni, Graha Maitri, Gana, Bhakoot, Nadi) with points and a plain-language meaning, which doshas are cancelled by classical exceptions, each person's Manglik status and the pair verdict, a caveat, and a link to the full free report. Each person needs a birth date and place; time is optional. Details are used in memory only and not stored. The score is one traditional input, not a decision about a relationship.

Inputs: person_a (required), person_b (required), lang.

learn_answerPlain-language guides to Vedic astrology (AstroCalc Learn)A
Read-onlyIdempotent
Inspect

Finds AstroCalc's plain-language guide chapters that answer a general question about Indian (Vedic) astrology, e.g. "what is Manglik dosha", "is 24 gunas enough", "what is Nadi dosha", "Saturn in the 7th house", "how do dashas work", "what is Sade Sati". Useful for general questions that need no birth data, when a source page the user can read is helpful; Hinglish works too, e.g. "Manglik dosh kya hota hai", "Nadi dosh kab cancel hota hai", "kitne gun milne chahiye". Returns up to 3 chapters with title, a short summary paragraph, the canonical URL, and links to the most relevant sections, in English or Hindi.

Inputs: question (required), lang.

life_timelineLife chapters and phases over the yearsA
Read-onlyIdempotent
Inspect

Timeline of life chapters (Vimshottari Mahadashas) and phases (Antardashas, or the finer Pratyantardashas for spans up to 3 years) with start and end dates over a chosen span, marking the one running today. From birth details (free, no sign-in) or for a person saved on the user's AstroCalc account (profile; that needs a free sign-in). Use for timing questions: when a hard period ends, which coming years suit marriage or a career move, what the next decade looks like ("shaadi ka yog kab hai", "agle 10 saal"). Read-only.

Inputs: lat, lon, date, from, +6 more.

match_my_profilesMarriage match between two saved peopleA
Read-onlyIdempotent

Use when the user asks whether two saved people are compatible, about a match for a son or daughter, or about Manglik dosha between them. Read-only.

From birth details (free, no sign-in) or for a person saved on the user's AstroCalc account (profile; that needs a free sign-in).
