Life Path Number (vedic)

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

Annotations already indicate the tool is read-only, non-destructive, idempotent, and closed-world. The description adds that it performs Vedic reduction on the birth date, which is useful but does not disclose nuanced behaviors like handling of master numbers or intermediate calculation steps. The description adds modest value 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 extremely concise: a single sentence stating the core function, a group tag, and an example request body. Every piece of information is purposeful and immediately accessible. No wasted words.

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 tool is simple and well-covered by annotations and schema. The description explains the essential function and provides an example. It does not detail the output format, but given the simplicity and the presence of an example, it is nearly complete. A brief note on the return value would push it to a 5.

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 has 100% parameter description coverage, so the baseline is 3. The description only mentions the 'date' parameter, aligning with the schema, but does not provide additional semantics for the optional location parameters (latitude, longitude, timezoneOffset). It does not detract but also does not enhance the schema's detail.

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 tool calculates the Life Path number from a birth date using the Vedic system. It is specific about the resource (life path number) and the method (Vedic reduction). However, it does not explicitly differentiate from other Vedic numerology siblings like expression or soul urge, making it slightly less than a 5.

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?

The description provides no guidance on when to use this tool versus alternative numerology tools. It does not mention prerequisites, exclusions, or relative contexts, leaving the agent to infer usage from the name alone.

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