ibge_indicadores

Read-onlyIdempotent

Query IBGE economic and social indicators including GDP, IPCA, unemployment, and population estimates.

Instructions

Queries IBGE economic and social indicators.

Available indicators:

Economic:

  • pib: GDP at current prices

  • pib_variacao: GDP variation (%)

  • pib_per_capita: GDP per capita

  • industria: Industrial production

  • comercio: Retail sales

  • servicos: Services volume

Prices:

  • ipca: Monthly IPCA

  • ipca_acumulado: 12-month IPCA

  • inpc: Monthly INPC

Labor:

  • desemprego: Unemployment rate

  • ocupacao: Employed people

  • rendimento: Average income

  • informalidade: Informality rate

Population:

  • populacao: Population estimate

  • densidade: Population density

Examples:

  • GDP: indicador="pib"

  • IPCA last 12 months: indicador="ipca", periodos="last 12"

  • Unemployment by state: indicador="desemprego", nivel_territorial="3"

  • List indicators: indicador="listar"

Use a different tool when:

  • Comparing/ranking localities → ibge_comparar

  • Census themes → ibge_censo

  • One municipality's panel → ibge_cidades

Behavior: read-only and idempotent — a live GET against the public IBGE SIDRA API. Returns Markdown plus a typed structuredContent payload.

Tool Definition Quality

A4.8/5.0
Behavior4/5

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

Annotations already provide readOnlyHint, destructiveHint, idempotentHint. Adds context: 'live GET against the public IBGE SIDRA API' and return format. No contradictions, but could disclose more about rate limits or authentication.

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?

Well-structured with headers, bullet lists, and examples. Front-loaded with purpose. Every sentence is meaningful and concise without redundancy.

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

Completeness5/5

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

Given high schema coverage, presence of output schema, and annotations, the description is complete. Covers purpose, alternatives, parameters with examples, and behavioral notes. No gaps identified.

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

Parameters5/5

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

Schema coverage is 100%, but the description adds extensive semantic meaning by listing every indicator and their meanings, plus examples mapping parameters to values (e.g., indicador='pib'). Goes well beyond baseline.

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?

Clearly states 'Queries IBGE economic and social indicators' and lists specific indicators. Distinguishes from siblings by explicitly saying when to use other tools like ibge_comparar, ibge_censo, and ibge_cidades.

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

Usage Guidelines5/5

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

Provides explicit guidance: 'Use a different tool when:' followed by three alternatives, plus examples of usage for various scenarios.

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