Official economic statistics for a country

hubvibe_data_macro

Read-onlyIdempotent

Economic data / macro indicators for any country, live: GDP, growth, GDP per capita, inflation (CPI), unemployment, population, interest rates, exchange rate, debt, trade, FDI or any World Bank indicator code. Annual for 200+ economies from the World Bank; monthly EU inflation and unemployment from Eurostat. Returns the series, latest and previous values, the change and the source's update stamp. Input: indicator, country; optional last, frequency. $0.10 per call. Returns: indicator{alias, code, name, unit}, country{code, name}, frequency, source, observations[{period, value}], observation_count, latest{}, previous{}, change{absolute, pct}, as_of, source_url, notes[], checked_at.

Input Schema

Name	Required	Description
`last`	No	Observations to return, newest last. Default 10.
`country`	Yes	ISO 3166 alpha-2 or alpha-3 (JP, KOR, DE), or an EU aggregate (EA20, EU27_2020) for monthly series.
`language`	No	Optional BCP-47 language tag (en, ja, ko, pt-BR): the human-readable strings of the result (notes, details, reasons) are translated into this language; data, codes, numbers and URLs are untouched. Default: as produced.
`frequency`	No	auto picks monthly where Eurostat publishes it, else annual.
`indicator`	Yes	Alias (gdp_usd, gdp_growth, gdp_per_capita_usd, inflation, unemployment, population, population_growth, current_account_gdp, reserves_usd, government_debt_gdp, exports_gdp, imports_gdp, fdi_inflows_usd, exchange_rate_per_usd, real_interest_rate, lending_rate, trade_gdp, internet_users_pct, life_expectancy, co2_per_capita) or a World Bank code (NY.GDP.MKTP.CD).

TDQS

A3.6/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description goes beyond them by disclosing cost ('$0.10 per call'), the data provenance (World Bank/Eurostat) and the presence of an update stamp — genuinely useful context an agent cannot get from the annotations. It omits rate limits or latency behavior, so not a 5.

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

Conciseness3/5

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

The opening is front-loaded and efficient, but the second half spends a long run-on enumerating the full return shape — indicator{}, observations[], latest{}, change{}, as_of, source_url — which duplicates the output schema that already exists. That verbosity dilutes an otherwise dense description.

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 5-parameter, read-only, open-world lookup tool with a full output schema and complete annotations, the description supplies the extra an agent needs: pricing, provider coverage, and the annual/monthly split. The only wasted content is the return-value enumeration, which the output schema already carries.

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

Parameters3/5

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 only restates the parameter names ('Input: indicator, country; optional last, frequency') and adds nothing about accepted formats beyond what the schema's own per-property descriptions already say (ISO codes, alias list, enum). Baseline applies.

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

Purpose4/5

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

It names a specific verb/resource set — 'Economic data / macro indicators for any country, live' — and enumerates the concrete indicator families (GDP, inflation, unemployment, etc.) plus the two upstream sources (World Bank, Eurostat). That is far more specific than a tautology, but it never distinguishes itself from plausible siblings such as hubvibe_data_query, hubvibe_opendata_table or hubvibe_finance_analytics, so it falls short of a 5.

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?

It explains source coverage ('Annual for 200+ economies from the World Bank; monthly EU inflation and unemployment from Eurostat') which implicitly guides frequency choice, and the schema documents 'auto'. However there is no explicit when-to-use/when-not guidance, no alternatives named among the many sibling data tools, and no mention of prerequisites. Usage is only implied.

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