Asterwise

Personality Number

asterwise_get_personality_number

Read-onlyIdempotent

Calculates the Personality number from consonants in the full name. All non-vowels (BCDFGHJKLMNPQRSTVWXYZ) contribute — Y is always a consonant. Reduces each name part separately, preserving master numbers 11, 22, 33.

WORKFLOW: BEFORE: None — standalone. AFTER: asterwise_get_numerology_profile — see all five core numbers together.

INPUT CONTRACT: name — Full legal name as used at birth. Example: 'Arjun Mehta', 'Sofia Rossi' Y is always a consonant — not treated as a vowel.

DO NOT CONFUSE WITH: asterwise_get_expression_number — all letters (Expression = Soul Urge + Personality). asterwise_get_soul_urge_number — vowels only.

A4.5/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds genuine beyond-annotation behavior: which letters contribute, that Y is treated as a consonant, that each name part is reduced separately, and that master numbers 11/22/33 are preserved. It omits determinism/edge cases for empty or non-Latin input, so not quite a 5.

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?

Front-loaded opening sentence states the calculation, then labeled blocks (WORKFLOW, INPUT CONTRACT, DO NOT CONFUSE WITH) make scanning trivial. Every sentence carries routing or domain information; nothing is padding.

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?

With an output schema present, the description need not describe returns, and it doesn't. Annotations plus description plus a linked full output/error contract cover everything an agent needs to call this 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 explains both parameters, making 3 the baseline. The description reinforces the name contract with examples and the Y rule, but adds nothing about response_format and little format/syntax detail beyond the schema.

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 ('Calculates the Personality number from consonants in the full name') and immediately distinguishes itself from the two closest siblings by naming them and the letter sets they use. An agent can route without 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 Guidelines5/5

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

Provides explicit WORKFLOW (BEFORE: none/standalone; AFTER: numerology profile), a DO NOT CONFUSE WITH block naming both asterwise_get_expression_number and asterwise_get_soul_urge_number with the discriminating rule, and an input contract. When-to-use and when-not-to-use are both covered.

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