Generate numerology chart - Complete numerology reading API

post_numerology_chart

Read-only

Generate a complete numerology chart from a full birth name and birth date in one call. It returns the six core numbers (Life Path, Expression, Soul Urge, Personality, Birth Day and Maturity) with their calculations and full interpretations, the four Pinnacles and four Challenges with their ages, Karmic Lessons, karmic debt in all five positions, Hidden Passion, Subconscious Self, Cornerstone, Capstone and First Vowel, the Birth Day profile for the exact day, lucky associations, the Maturity activation status, the Personal Year with the current Personal Month, and a written summary, in the language set by lang. The age behind the Maturity status, the Personal Month and the Personal Year are read on targetDate, the current UTC date when omitted, and currentYear overrides the Personal Year alone. Built for full numerology readings, PDF reports, onboarding profiles and AI agents.

Input Schema

Name	Required	Description	Default
`day`	Yes	Birth day (1-31)
`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
`year`	Yes	Birth year between 100 and 2100. Supports historical figures like Einstein (1879) and Shakespeare (1564).
`month`	Yes	Birth month (1-12)
`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.
`fullName`	Yes	Full birth name as it appears on the birth certificate. Used for every letter-based number in the chart: Expression, Soul Urge, Personality, Karmic Lessons, Hidden Passion, Subconscious Self and the special letters. A name in any script is converted to Latin letters before it is counted, Cyrillic and Greek as the passport spelling and accents folded to the base letter, and the calculation lists the letters counted. For a script that does not write its vowels, send the Latin spelling the person uses.
`targetDate`	No	Date to read the chart on, in YYYY-MM-DD format, in the years 100 to 2100, on or after the birth date. Send the local date of the user for an exact answer: it sets maturityStatus.currentAge and isActive, the Personal Month, and the Personal Year when currentYear is absent. Defaults to today (UTC).
`currentYear`	No	Calendar year for the Personal Year. When omitted it is the year of targetDate, or of the current UTC date when targetDate is omitted too. It moves the Personal Year only: the nested personalMonth and maturityStatus.currentAge read targetDate.

Output Schema

Name	Required	Description	Default
`profile`	Yes
`summary`	Yes
`coreNumbers`	Yes
`maturityStatus`	Yes
`birthDayProfile`	No

A4.4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint and non-destructive, so the safety profile is covered. The description adds genuinely behavioral context beyond them: targetDate defaults to the current UTC date, currentYear moves only the Personal Year while maturity and Personal Month read targetDate, and the age behind Maturity is derived from targetDate. 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?

Purpose is front-loaded in the first clause and the paragraph waste is minimal. The long enumeration of return fields is somewhat redundant given an output schema exists, which keeps it from a 5, but the enumeration also signals completeness to a selecting agent.

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?

For an 8-parameter tool with an output schema, the description covers the gaps that matter: language fallback, name-script normalization, date defaults, and the interaction between targetDate and currentYear. Nothing needed to invoke it correctly is left to inference.

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

Parameters4/5

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

Schema description coverage is 100%, so the baseline is 3, but the description adds cross-parameter meaning the schema states only per-field: that lang governs the whole response and that currentYear overrides the Personal Year alone rather than the whole chart. That synthesis is real added value over the individual field descriptions.

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?

States a specific verb and resource ('Generate a complete numerology chart') plus the inputs, and explicitly distinguishes itself from the single-number siblings by delivering the whole chart in one call. An agent can tell it apart from post_numerology_life_path or post_numerology_expression without opening a schema.

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?

Names use contexts explicitly ('full numerology readings, PDF reports, onboarding profiles and AI agents') and implicitly routes agents away from single-number siblings by promising the complete chart. It does not state an explicit when-not or name the cheaper alternatives, so it stops short of a 5.

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