Input Schema

TableJSON Schema

Name	Required	Description	Default
`date`	Yes	Birth date in YYYY-MM-DD format
`lang`	No	Response 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
`time`	Yes	Birth time in 24-hour HH:MM:SS format
`focus`	No	Which signification vocabulary the houseThemes map returns. "general" gives the classical bhava significations (self, wealth, siblings, home, and so on). "finance" gives the money reading of the same twelve bhavas, so house 2 returns income and savings, 5 speculation and risk appetite, 8 sudden money and leverage, 11 gains and profits, and 12 expenses and capital outflow. Use "finance" for wealth, income, business and market timing questions in Krishnamurti Paddhati, where the significator house groups 2, 6, 10, 11 for earned income and 5, 8, 11 for speculation are read against a running dasha. Defaults to "general".	general
`compact`	No	Set 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.
`ayanamsa`	No	Ayanamsa system for sidereal conversion. "kp-newcomb" uses the KP-Newcomb dynamic formula (most common for KP). "kp-old" uses the Krishnamurti original table. "lahiri" uses Lahiri/Chitrapaksha ayanamsa matching most traditional Vedic software. "raman" uses the B.V. Raman ayanamsa, about 1.45 degrees below Lahiri. "custom" allows providing your own value via ayanamsaValue. Defaults to "kp-newcomb".	kp-newcomb
`latitude`	Yes	Birth location latitude in decimal degrees
`timezone`	No	Timezone offset from UTC in hours. Defaults to 5.5 (IST) for Vedic astrology.
`longitude`	Yes	Birth location longitude in decimal degrees
`ayanamsaValue`	No	Custom 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.

A3.8/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the behavior's safety is covered. The description adds true transparent behavioral content: the cusps are Unequal Placidus, the calculation includes three layes of lords, and supports dynamic and custom ayanamsa. This goes beyond merely restating 'read-only'.

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 core behavioral sentences are concise and front-loaded, with the essential first sentence followed by useful context and return info. The trailing 'SEO: Placidus house cusps API...' keyword block adds no agent-facing value and should be removed, so the description does not earn full structure credit.

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 10-parameter tool with no output schema, the description and rich input schema are sufficient for an agent to select and call the tool correctly. It conveys output fields (sign-lord, nakshatra-lord, sub-lord, all 12 cusps) broadly, though it could go slightly further in describing the exact returned shape beyond top-level data.

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?

Schema description coverage is 100%, so parameters height, time, coords, aoanamsa, compact, focus, timezone, etc. are already fully described. The description's mention of 'Dynamic KP-Newcomb or custom ayanamsa support' reaffirms but does not importantly deepen the schema's ayanamsa and ayanamsaValue documentation.

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 opens with a specific verb and resource: 'Calculate unequal Placidus house cusps with ruling sign-lord, nakshatra-lord, and sub-lord for each cusp.' It also states the deliverable — all 12 house cusps with KP sub-division details — which clearly distinguishes it from sibling tools like kp_planets, kp_chart, and kp_horary.

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

Usage Guidelines3/5

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

It gives broad application context ('Used in KP horary astrology, cusp sub-lord analysis, and birth chart rectification'), which helps an agent knows the analytical scenario. However, it does not explicitly compare itself to close siblings such as post_vedic_astrology_kp_h_orary or post_vedic_astrology_kp_chart, and it gives no 'when not to use' guidance.

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.
