Expression / Destiny (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's mention of 'calculate' adds little. It specifies 'full birth name letters' and 'all letters, reduced', providing minimal extra context 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.

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

The description is short and includes a group label, but the example with a non-existent 'name' parameter is confusing and undermines conciseness. It could be restructured to avoid misleading examples.

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?

The description does not explain what the tool returns, which is problematic since there is no output schema. It also fails to clarify the purpose of optional parameters like latitude, longitude, and timezoneOffset. The required 'date' parameter is mentioned, but the overall context is incomplete.

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 description implies a 'name' parameter with the example, but the input schema does not include any name field. This is misleading and contradicts the schema. The description adds confusion rather than clarity about parameters.

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 the verb 'calculate' and the specific resource 'Expression/Destiny number' with the Kabbalistic phonetic system, distinguishing it from numerous sibling numerology tools for different systems and numbers.

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 is provided on when to use this tool versus alternatives like Chaldean or Pythagorean Expression numbers. There is no mention of prerequisites, exclusions, or contexts where this tool is preferable.

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