Life Path Number (pythagorean)

numerology_pythagorean_life_path
Read-onlyIdempotent

Calculate your Life Path number from your birth date using the Pythagorean numerology system. Reduce year, month, and day to determine your core personality and life journey.

Instructions

Calculate the Life Path number from birth date (year + month + day, reduced). Numerology — Pythagorean system.

[Group: Numerology — Pythagorean]

Example request body: {"name":"John Smith","date":"1990-05-15"}

Behavior4/5

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

Annotations already indicate readOnly, idempotent, non-destructive behavior. The description adds that the calculation involves reduction, which is useful context. No contradictions with 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?

The description is concise with two sentences plus an example and group label. It is front-loaded with the main action, but the group line could be formatted separately. Still, it is efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description explains the basic calculation but omits details like whether master numbers (11,22) are considered. No output schema is provided, so the agent cannot infer the return format. Some gaps remain for a complete understanding.

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% with detailed descriptions for all parameters. The tool description only mentions 'date', adding no extra semantic value over the schema. Baseline score of 3 is appropriate.

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 the verb 'Calculate' and the resource 'Life Path number' from a birth date, and it specifies the Pythagorean system. It effectively distinguishes from sibling tools like chaldean or kabbalistic life path tools.

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?

The description implies usage for Pythagorean life path calculation but does not explicitly state when to use this tool versus alternatives. Given many sibling tools exist, some exclusion guidance would improve clarity.

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