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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not mention side effects, authentication needs, rate limits, or edge case handling (e.g., future birth dates). The only additional information is a price note, which is not behavioral.

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 starts with a cluttered list of synonyms and includes a price note, which adds noise. The core functionality is stated in a single sentence, but the opening could be more streamlined.

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 lists four outputs but does not explain their format or provide error handling details. No output schema exists, so the description should be more complete to cover return values and edge cases.

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%, both parameters are described in the schema. The description restates the schema but does not add new semantic meaning beyond 'birth' and 'on' dates. The price note is irrelevant to parameter semantics.

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 computes Chinese nominal age (xu sui), Western actual age, days lived, and lunar birthday from any birth date. It uses specific verbs and resources, and the list of sibling tools shows it is distinct from other Chinese calendar 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 implies usage for age calculations but does not explicitly state when to use this tool versus alternatives or provide when-not-to-use guidance. With many sibling tools, more explicit context would be helpful.

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