Generate detailed people

generate_detailed_people
Read-only

Generate synthetic Nigerian people with consistent identity, health, financial, kin, education, work, and vehicle records. Control count, age range, gender, and language for tailored test data.

Instructions

Generates an array of synthetic detailed people. Each record includes geographically consistent identity data plus health, financial, kin, education, work, and vehicle records. Returns one record by default. Defaults to ages 22-65; widen the range with minAge and maxAge.

  3. First observedv1.0.1

TDQS

A4.2/5.0
Behavior4/5

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

Annotations already cover readOnlyHint=true and destructiveHint=false, lowering the bar. The description still adds real behavioral value by disclosing that output is an array, default count is 1, default age range is 22-65, and records bundle many data categories. No hidden mutation or side effects are left undisclosed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tight sentences: first gives verb and resource, second enumerates record contents, third gives defaults and how to change them. Every sentence carries useful information and the key facts are front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a generation tool with six optional parameters, an output schema, and readOnly annotations, the description covers purpose, contents, defaults, and age-range adjustment. It doesn't need to explain return values because an output schema exists; the only minor omission is not mentioning seed reproducibility, but the schema already handles that.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description goes beyond the schema by revealing the default count and default age range and by explaining that minAge/maxAge widen the range. Seed, gender, and language are adequately described in the schema, so no further compensation is needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb ('generates') and resource ('array of synthetic detailed people'), and enumerates the record contents (identity, health, financial, kin, education, work, vehicle). This clearly distinguishes it from siblings like generate_person or generate_people by the 'detailed' and multi-record scope.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description states defaults (one record, ages 22-65) and how to widen the age range, giving clear context for typical use. However, it never names sibling tools or specifies when to choose this over generate_people, generate_detailed_person, or generate_consistent_people; selection must be inferred from the name and content detail.

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