One call. Three things your agent can use.

A headline it can quote, facts it can reason over, and pre-rendered prose it can pass through. No parsing. No schema mapping. No post-processing.

The native bears a **Vrishcika ascendant** with its lord Mangala
placed in the 1st house in own sign, forming Ruchaka Yoga
(BPHS 75.4). Moon occupies 10H in Simha — public career and
visibility are illuminated. Active Mangala mahadasha through...

02Classical depth

The parts everyone else hand-waves.

Every rule in the engine cites its classical source. 409 yogas. 1,264 natal insight rules. 183 evaluable classical predicates. Compiled from BPHS, Raman, Jaimini, Saravali, and Phaladipika — and checked against the texts, not against a metric.

Full-fidelity Shadbala

Six strength components computed in virupas per graha — Sthana, Dig, Kala, Cheshta, Naisargika, Drik — plus per-house Bhava Bala. Hand-calculating one chart takes a practitioner hours; most software approximates or skips components.

Reproduces the fully-worked Standard Horoscope example in Raman's Graha and Bhava Balas to within ~4 virupas per graha (max |Δ| 4.07) — pinned by a test you can run.

5 dasha systems

Vimshottari to 5 recursive levels (Maha → Prana), plus the Jaimini rasi-dasa stack — Chara, Sthira, Niryana Shoola, Maheswara — which almost no software implements at all.

All five period systems addressable from the rule corpus, not just displayed.

409 yogas with cancellation

Detection is the easy half. Each detected yoga runs a 6-stage qualification (detection → eligibility → strength → purity → timing → domain) and a defeasible cancellation pass.

16 bhanga (cancellation) rules, including the 8 BPHS Ch.10 arishtabhanga that form the Balarishta defeat-graph, plus neechabhanga/kemadruma/combustion cancellations — defeat chain in the response (suppressed_by on insights, cancelled/cancellation_reason on yogas).

The Jaimini toolkit

Chara karakas, Karakamsha, Arudha lagna + Upapada, and the special lagnas (Bhava, Hora, Ghatika, Indu) — computed, predicate-addressable, and used by the rule corpus, not just displayed.

Every construct reachable from rule predicates in the DSL registry.

50 Tajika Sahams

The complete Neelkanthi saham set, implemented from the published per-saham formula definitions — including four formula corrections to a widely-circulated shorter set.

Formulas from Nilakantha's Tajik Neelkanthi, cross-checked by internal day/night-reversal relationships.

life_events 125 timed life-event rules with weighted natal/dasha/transit triggers — every trigger cited to Raman or BPHS.
ephemeris Pure-Rust clean-room — VSOP87A (planets) + ELP/MPP02 (Moon), IAU 2006 · Moon within 0.015″ of JPL Horizons at J2000 · all grahas cross-checked against an independent ephemeris across 500 charts, 0 failures.

Sources: Brihat Parashara Hora Shastra · B. V. Raman · Jaimini Upadesha Sutras · Saravali · Phaladipika · Tajik Neelkanthi — every rule carries its citation.

03Full provenance

Every claim has a paper trail.

Call explain on any chart result. KundaliMCP traces it back through 6 stages — from the VSOP87A sky position to the classical verse. No black boxes. Ever.

04Anuvada — multilingual ontology

Seven languages. One ontology.

Anuvada is not a translation layer bolted on top. Every Vedic concept — yoga, dosha, nakshatra, graha — is a JSON-LD entity with axes, grammar rules, and validated surfaces in all seven languages from compile time. Add a new language without touching the engine.

JSON-LD ontology

Every yoga, graha, rashi, nakshatra, and dosha is a structured entity with axes — quality, category, domain, timing, deity. Machine-readable definitions, not a word list.

Composition rules

Each language carries its own grammar templates and morphology rules. 'Gajakesari Yoga is active during Jupiter mahadasha' conjugates correctly in Hindi — not just transliterated.

SHACL validation

Shape constraints enforce completeness at build time. A concept with a missing Tamil surface fails the build — no silent gaps, no half-translated responses.

Extensible by design

Add a new language by contributing vocabulary, composition rules, and SHACL shapes. The engine picks it up automatically at the next snapshot compile.

Adding a new language means adding vocabulary, grammar templates, and SHACL shape files to the anuvada/ directory. The engine compiles it automatically — no code changes required.
