Kundlit Vedic Astrology

Vedic numerology from date of birth

get_numerology
Read-onlyIdempotent

Returns a Vedic numerology reading from a date of birth alone: the mulank (root / psychic number, from the day of the month) and the bhagyank (destiny / life-path number, from the whole date), each with its ruling planet and traditional meaning, plus the classical lucky attributions -- numbers, colours, weekday, direction, gemstone. Optionally adds the Chaldean naam-ank when a name is supplied. Use this when the user asks about their number, life path or lucky colour/day/stone. It is NOT astrology and shares nothing with the chart tools: for a birth chart use get_janam_kundali, for a birth star use get_birth_details. Read-only deterministic arithmetic over the classical Chaldean number table -- no ephemeris is touched, and the result's Source line says so. No writes, no auth, at least 30 requests/min/IP per server instance. Birth time and place are not used, so none is asked for.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
nameNoFull name in Latin letters, e.g. "Rahul Sharma" -- it must contain at least one A-Z letter. Optional: supply it to add the Chaldean name number and its meaning; omit and only the date-derived numbers are returned.
birth_dateYesDate of birth as YYYY-MM-DD, e.g. 1992-03-14. Must be a real calendar date. Birth time, timezone and place have no effect in numerology and are not accepted.

A5/5.0
Behavior5/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint. The description adds valuable context: 'Read-only deterministic arithmetic over the classical Chaldean number table -- no ephemeris is touched... No writes, no auth, at least 30 requests/min/IP per server instance.' This goes beyond annotations with rate limits and authentication details.

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

Conciseness5/5

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

The description is well-structured and front-loaded, starting with the main purpose, then detailing outputs, usage, exclusions, and behavioral notes. Every sentence adds value, and there is no redundancy.

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?

Despite having no output schema, the description comprehensively explains what is returned, including the source line. It covers all relevant aspects for a deterministic, read-only tool with no auth requirements.

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 description coverage is 100%, but the description adds meaning beyond the schema: it explains the role of each parameter (name adds Chaldean naam-ank, birth_date for date-derived numbers), provides examples, and clarifies constraints (e.g., name must contain at least one A-Z letter).

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 Vedic numerology readings from date of birth, listing specific outputs (mulank, bhagyank, ruling planet, meaning, lucky attributions). It explicitly distinguishes itself from astrology and sibling tools like get_janam_kundali and get_birth_details.

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 provides explicit guidance on when to use the tool ('when the user asks about their number, life path or lucky colour/day/stone') and when not to use it, citing specific alternatives ('for a birth chart use get_janam_kundali, for a birth star use get_birth_details'). It also explains optional usage with a name.

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.
