Life Path Number (kabbalistic)

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

Annotations already declare readOnlyHint=true and idempotentHint=true, so the description does not need to repeat those. It adds that the date is 'reduced,' but lacks other behavioral details (e.g., output format, error conditions). The description provides marginal extra context beyond annotations.

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

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

The description is relatively concise with two sentences and a group label. However, the group label ('[Group: Numerology — Kabbalistic (phonetic)]') is redundant given the title, and the example adds noise without clear benefit. The structure is adequate but not optimal.

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

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

Given the large set of sibling numerology tools, the description does not help an agent distinguish between this and similar tools (e.g., 'numerology_kabbalistic_strict_life_path'). There is no output schema, and the description does not describe the return value, leaving the agent uncertain about what the tool outputs.

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

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

The input schema already describes all parameters (100% coverage). The description adds no additional meaning and, in fact, includes an example with a 'name' field that is not in the schema, which could mislead the agent. This reduces clarity.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Calculate the Life Path number from birth date' and specifies the system as 'Kabbalistic (phonetic).' The verb 'calculate' and resource 'Life Path number' are specific. However, it does not explicitly differentiate from sibling tools like 'numerology_kabbalistic_strict_life_path,' so it loses a point.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

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

No guidance on when to use this tool versus other numerology life path tools (e.g., Chaldean, Pythagorean) or when not to use it. The description merely provides an example, offering no context for selection.

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