Janam Kundali (Vedic birth chart)

get_janam_kundali
Read-onlyIdempotent

Returns a full Vedic birth-chart (janam kundali) summary for one person from their birth date, time and place: the lagna (ascendant) with sign, nakshatra, pada and lord; all nine grahas with sidereal sign, house, nakshatra, pada, dignity and retrograde/combust flags; the currently running Vimshottari mahadasha and antardasha with end dates, omitted only for a chart cast at the present moment, where no dasha has yet elapsed; and the most notable classical yogas detected, with a count of how many were found in all. Use this when the user wants their whole chart read. Prefer the cheaper, narrower sibling when the question is narrow: get_birth_details for only nakshatra / moon sign / lagna, get_dasha_periods for the full dasha timetable, get_upapada_arudha for the Jaimini layer, get_transits for where the planets are RIGHT NOW rather than at birth. Read-only deterministic computation (Swiss Ephemeris, Lahiri ayanamsa, whole-sign houses); no writes, no auth. Rate limits are counted per server instance: at least 30 requests/min/IP on this endpoint, plus a shared engine budget of at least 60/min/IP across all birth-chart tools. Accuracy depends on birth-time precision.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
placeNoPlace as free text, "City, State, Country" -- e.g. "Jaipur, Rajasthan, India". Preferred input: it is geocoded to coordinates and an IANA timezone server-side, and any city worldwide works. Omit only if you pass latitude + longitude + timezone instead.
latitudeNoLatitude in decimal degrees, -90 to 90, north positive (Delhi = 28.6139). Use only when `place` is omitted, and then longitude and timezone are required too.
timezoneNoIANA timezone name, e.g. "Asia/Kolkata" or "America/New_York" (never an offset like "+05:30"). Required when latitude/longitude are used; ignored when `place` is given.
longitudeNoLongitude in decimal degrees, -180 to 180, east positive (Delhi = 77.2090). Use only when `place` is omitted.
birth_dateYesBirth date in the Gregorian calendar as YYYY-MM-DD, e.g. 1992-03-14. Years 1200-2400 only, and it must be a real calendar date (2023-02-29 is rejected).
birth_timeYesBirth time on the local clock at the birth place, HH:MM in 24-hour format (00:00-23:59), e.g. 06:45 or 18:20. Not UTC. Required and not defaulted: the ascendant moves about one degree every four minutes, so a guessed time gives a guessed chart.

TDQS

A4.9/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already provide readOnlyHint, openWorldHint, idempotentHint, destructiveHint=false. The description adds further behavioral context: deterministic computation, no writes, no auth, rate limits, and accuracy dependence on birth-time precision. No contradictions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is comprehensive and well-structured, front-loading the main result. While it is lengthy, every sentence adds value, making it a minor deduction for slight verbosity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 6 parameters, no output schema, and high complexity, the description covers purpose, usage guidelines, behavioral traits, and parameter details thoroughly, including an important note about dasha omission for present-moment charts.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, but the description adds valuable context beyond schema: explains the place vs. lat/lon/timezone relationship, required format for birth_date and birth_time, and why birth_time must be accurate. This significantly aids correct parameter usage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it returns a full Vedic birth-chart summary, listing components like lagna, grahas, dasha, and yogas. It distinguishes itself from sibling tools by naming cheaper alternatives for narrower queries.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly says 'Use this when the user wants their whole chart read' and provides clear guidance on when to use sibling tools like get_birth_details, get_dasha_periods, etc.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.7/5.0
Disambiguation5/5

Each tool targets a distinct astrological calculation or domain: dosha checks, birth charts, compatibility, muhurta, panchang, numerology, transits, and Jaimini layer. Even similar tools (e.g., get_panchang vs get_muhurta_timings) are explicitly differentiated in their descriptions, and cross-references tell the agent which to use for which question.

Naming Consistency5/5

All tools follow a consistent verb_noun pattern: 'get_' for data retrieval and 'check_' for yes/no dosha assessments. No camelCase or mixed conventions. The naming is predictable and readable.

Tool Count4/5

At 17 tools, the set is slightly above the ideal 15-tool ceiling, but it is well-scoped for the breadth of Vedic astrology: each tool earns its place covering a distinct sub-domain. The count feels justified rather than bloated.

Completeness5/5

The surface covers the full lifecycle of a birth chart (details, full kundli, dasha), doshas (manglik, kaal sarp, sade sati), compatibility (kundli match), event planning (muhurta, panchang, year events, eclipses), numerology (personal, mobile, name), and advanced layers (upapada, transits). No obvious gaps or dead ends.
