Calculate Personality number - Outer personality numerology API

post_numerology_personality

Read-only

Calculate the Personality number from the consonants of a full birth name with Pythagorean numerology. Every letter other than A, E, I, O and U is a consonant, Y and W included; master numbers 11, 22 and 33 are kept and a karmic debt of 13, 14, 16 or 19 is flagged with its meaning. The response lists every consonant name by name and returns a full interpretation of first impressions, public image, career and relationships in the language set by lang. Built for personal branding apps, social and dating profiles, coaching tools and AI agents.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`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
`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. Its consonants give the Personality number, so a name with none is refused. 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.

TDQS

A3.9/5.0

Behavior4/5

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

Annotations already cover the safety profile (readOnly, non-destructive), so the description is free to add real behavior: master numbers 11/22/33 preserved, karmic debt of 13/14/16/19 flagged with meaning, consonant list returned, and a name with no consonants refused. These are non-obvious traits beyond the annotations.

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?

Front-loaded with the calculation rule, and the behavioral details (master numbers, karmic debt, script folding) are crammed densely but usefully into the first two sentences. The closing marketing sentence about target apps is the only padding, keeping this just short of a 5.

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?

With an output schema present, the description need not detail return values, yet it still previews the interpretation scope and language behavior, which is helpful. All inputs are covered and the refusal condition is stated, so an agent has what it needs to call the tool correctly.

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 the schema already documents lang, compact and fullName thoroughly. The description only echoes the lang linkage and the consonant dependence of fullName, adding no syntax or format detail beyond the schema. Baseline 3 applies.

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 (Calculate) and resource (Personality number) plus the exact input basis (consonants of a full birth name) and the system (Pythagorean). This distinguishes it from vowel-based siblings like soul_urge and all-letter tools like expression without the agent opening any schema.

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 defines the letter rule (everything but A,E,I,O,U, Y and W included) and lists target audiences, which implies when it is appropriate, but it never names an alternative sibling or states an exclusion condition. Usage is inferable from the vowel/consonant split rather than made explicit.

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