Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
dateYesBirth date in YYYY-MM-DD format. Date determines planetary positions and nakshatra calculations for Vedic kundli (janam patri). Accurate birth date is essential for dashas, yoga calculations, and divisional charts (vargas).
langNoResponse language (BCP 47). Supported: en, tr, de, es, hi, pt, fr, ru, zh-Hans, zh-Hant. Defaults to en. Coverage varies by domain, and a field with no translation in the requested language returns English.en
timeYesBirth time in 24-hour HH:MM:SS format. Time is CRITICAL for Lagna (Ascendant) calculation and house divisions. It changes every two hours roughly. Even minutes matter for accurate nakshatra pada and divisional chart (D9, D10) calculations. Without exact time, Lagna and house-based predictions will be incorrect.
compactNoSet true for the same data in a compact shape: arrays of same-shaped objects arrive columnar as {"__cols":[names],"__rows":[[values]]}. Lossless, typically 40 to 52 percent fewer tokens.
ayanamsaNoSidereal frame (ayanamsa) the chart is cast in. "lahiri" is Lahiri/Chitrapaksha, the traditional Vedic standard used by most software, and is the default. "raman" is the B.V. Raman ayanamsa from Hindu Predictive Astrology, about 1.45 degrees below Lahiri. "kp-newcomb" and "kp-old" are the two Krishnamurti Paddhati frames. "custom" takes your own value in degrees via ayanamsaValue, for reconciling exactly against a specific reference program. The frame rotates the whole zodiac, so a graha sitting within 1.45 degrees of a boundary can change rashi or nakshatra when you switch: pick the one your reference software uses and keep it.lahiri
latitudeYesBirth location latitude in decimal degrees. Location determines local sidereal time for Lagna calculation and affects bhava (house) cusps. Example: Delhi 28.6139, Mumbai 19.0760, Kathmandu 27.7172.
timezoneNoTimezone: IANA name (e.g. "America/New_York", "Europe/London") OR decimal hours from UTC (e.g. -5 for EST, 1 for CET). IANA strings are resolved to the DST-correct offset for the given date, so you can pass `cities[0].timezone` from /location/search directly. Defaults to 5.5.
longitudeYesBirth location longitude in decimal degrees. Affects local time calculations and ayanamsha adjustments. Example: Delhi 77.2090, Mumbai 72.8777, Kathmandu 85.3240.
ayanamsaValueNoCustom ayanamsa value in degrees. When provided, overrides the computed ayanamsa from the selected type. Use for testing with specific ayanamsa values or matching a particular reference source.

TDQS

A4/5.0
Behavior4/5

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

Annotations already mark this read-only and non-destructive, so the description is not burdened with safety disclosure. It adds meaningful behavioral detail by naming the six strength components, the Ishta/Kashta Phala outputs, and the scope of all 7 classical planets, which makes expected output content transparent.

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

Conciseness3/5

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

The opening sentence is detailed and front-loaded, but the description loses points with a trailing SEO keyword block ('Shadbala calculator API, planetary strength Vedic astrology, graha bala, Ishta Kashta Phala') that adds no decision-making value. The middle sentence on 'Essential for...' is useful, but the ending padding makes it somewhat less concise.

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

Completeness4/5

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

For a read-only calculation tool with full schema documentation and no output schema, the description gives a solid set of expected outputs and context. It lacks exact response shape or behavior for non-classical planets, but the agent likely knows what the tool will return and how to invoke it.

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

Parameters3/5

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

The input schema already documents all parameters thoroughly, including critical details on date format, time sensitivity, ayanamsa differences, and DST-aware timezones. The description adds no new parameter-level semantics, which is acceptable since schema coverage is 100%.

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 the verb and resource: 'Calculate complete Shadbala' with six distinct strength components plus Ishta Phala, Kashta Phala, strength ratio, and ranking. It differentiates this endpoint from sibling tools like bhava_bala and ashtakavarga by describing its exact output focus and authoritative basis (BPHS).

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

Usage Guidelines4/5

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

It gives specific use contexts: Vedic birth chart analysis, dasha prediction, transit interpretation, and yoga assessment. It does not explicitly name an alternative endpoint or state 'when not to use this', but the intended context is clearly implied and distinguishable from sibling tools.

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

A3.6/5.0
Disambiguation3/5

Many tools have overlapping concepts (multiple dasha levels, monthly variants, aspects, transit), but detailed descriptions clarify each one's distinct purpose. Still, a few pairs like planetary_positions vs birth_chart or aspects_monthly vs aspects_lunar could confuse an agent initially.

Naming Consistency5/5

All tools follow a strict get_vedic_astrology_* or post_vedic_astrology_* prefix with snake_case resource names. The pattern is predictable and uniformly applied, including the hierarchical dasha drill-downs, making it easy to infer tool families.

Tool Count1/5

With 50 tools, the server is extremely heavy. Many are monthly, interval, or sub-level variants that could be parameterized or consolidated, making the set feel bloated and difficult to navigate for an agent.

Completeness5/5

The tool set covers nearly the entire Vedic astrology domain: reference data (nakshatras, rashis, yoga glossary), core charts (birth, navamsa, divisional), dasha hierarchy, transits, compatibility, doshas, panchang, KP system, and advanced calculations like Shadbala and Ashtakavarga. No significant gaps are apparent.
