get_numerology

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

The description provides behavioral context by stating it is based on date of birth, but no annotations are provided to cover safety or side effects. Since it is a read-only operation, no destructive behavior is expected, but the description does not explicitly confirm this.

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 (two sentences), lists outputs clearly, and is front-loaded with key information. Every sentence is meaningful and there is no repetition.

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 tool's moderate complexity (2 parameters, no output schema), the description is fairly complete. It covers inputs and outputs adequately, though it could mention that the output might include warnings or default values for optional name.

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 both parameters with 100% coverage (dob format and name as optional). The description adds value by explaining that 'name' is used for name number calculation, which is not in the schema. This extra context justifies a 4.

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 provides a full Vedic numerology profile and lists specific outputs (Life Path number, Destiny number, etc.). It distinguishes itself by focusing on numerology as opposed to astrology or other features available in sibling tools.

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 implicitly suggests using this tool when a numerology profile is needed, but it does not explicitly state when not to use it or name alternatives. Sibling tools like 'get_kundali_match' or 'get_moon_sign' serve different purposes, but the description does not guide the agent away from them.

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