Birthday (kabbalistic-strict)

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true. The description states 'Calculate', which is consistent, but adds no additional behavioral context such as what the output contains or any limitations beyond what annotations provide.

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 concise, front-loaded with the purpose, and includes a clear example request body. Every sentence adds value without redundancy.

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?

For a simple calculation tool with full schema coverage and annotations, the description is adequate but lacks context about the output format or what the Birthday number represents, which an agent might need for downstream use.

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?

Schema coverage is 100%, so the schema already describes all parameters (date required; latitude, longitude, timezoneOffset optional). The description does not explain the optional parameters' relevance to the birthday number calculation, leaving the agent to infer from the schema alone.

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 it calculates the Birthday number from the day-of-birth digit using the Kabbalistic (Mathers strict) system. However, it does not differentiate from the similar sibling tool 'numerology_kabbalistic_birthday', which likely computes the same number but without the 'strict' variant.

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 'numerology_kabbalistic_birthday' or other numerology birthday tools. Missing 'use this when' or 'prefer X for' statements.

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