ibge_paises

Read-onlyIdempotent

Query international country data from IBGE by listing all countries, retrieving details like area, languages, currency, searching by name, or filtering by region using ISO alpha-2 codes.

Instructions

Queries international country data via IBGE.

Features:

List all countries (following UN M49 methodology)
Country details (area, languages, currency, location)
Search countries by name
Filter by region/continent

Available regions: americas, europa, africa, asia, oceania

Country codes: Use ISO-ALPHA-2 (e.g., BR, US, AR, PT, JP)

Examples:

List all: tipo="listar"
Brazil details: tipo="detalhes", pais="BR"
Search: tipo="buscar", busca="Argentina"
Americas countries: tipo="listar", regiao="americas"
Available indicators: tipo="indicadores"

Behavior: read-only and idempotent — a live GET against the public IBGE Países API. Returns Markdown.

TDQS

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnly/idempotent/openWorld/non-destructive, so the description's 'read-only and idempotent' is largely redundant; however it adds genuinely new context — a live GET against the public IBGE Países API and Markdown output format. That is useful beyond the structured fields, though it omits any auth/rate-limit notes.

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

Conciseness4/5

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

Front-loaded with a one-line purpose, then feature bullets, region/code conventions, examples, and behavior — highly scannable. Slightly verbose, and the 'Available indicators: tipo="indicadores"' example is a bit misleading since indicator IDs go in a separate parameter.

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?

With an output schema present, return values need not be explained, and the description still covers all five parameters, valid enum values, code formats, and invocation examples. The only small gap is the ambiguity between the indicators enumeration and the indicadores parameter.

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 coverage is 100%, so parameter docs are already complete; the description still adds value by listing the valid region values, prescribing ISO-ALPHA-2 codes with examples (BR, US, AR, PT, JP), and demonstrating how parameters combine per operation. It only marginally clarifies how the 'indicadores' parameter relates to tipo='indicadores'.

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?

States a specific verb and resource (queries international country data via IBGE) and enumerates the concrete operations: list, details, search, filter by region. The word 'international' implicitly separates it from the Brazilian-scoped siblings (ibge_estados, ibge_cidades, ibge_municipios, ibge_localidade), so an agent can route correctly.

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

Usage Guidelines4/5

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

The Examples block gives a use pattern for each mode (listar, detalhes, buscar, listar+regiao, indicadores), which effectively says when to combine which parameters. It does not name a sibling alternative or an explicit 'do not use this for X' exclusion, so it stops short of a 5.

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