get_date_of_birth_detail

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

No annotations are provided, so the description must fully disclose behavioral traits. However, it does not mention that it is likely read-only, what data it relies on (date of birth and gender), or what the output looks like beyond the schema. The description adds little transparency.

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 a single sentence, but it is under-specified and does not earn its place by conveying enough information. It is not concise in a useful way; it is simply minimal and vague.

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 that the tool has three parameters, an output schema, and related sibling tools, the description lacks context on what 'detail' means, when to prefer this tool, and what the output represents. It is barely adequate for a basic understanding.

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 schema documents all three parameters with clear descriptions (100% coverage), so the baseline is 3. The description itself does not add extra meaning about how format or gender affect the result, but it does not need to compensate significantly given the schema coverage.

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 states the action ('get') and the resource ('date of birth'), but 'the detail' is vague and does not specify what details are returned or how it differs from sibling fortune tools. It is not a tautology, but it lacks specificity.

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 the sibling tools (get_daily_fortune, get_general_fortune). The description does not mention any alternatives, prerequisites, or typical use cases.

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