Suprimento de fundos

senado_suprimento_fundos
Read-onlyIdempotent

Suprimento de fundos do Senado (adiantamentos a supridos): relação anual de supridos, atos de concessão, empenhos, movimentações ou transações de cartão corporativo, conforme tipo. Retorna { ano, tipo, count, total, registros } (snake_case da API administrativa), filtrável por filtro textual e limitado por limite (padrão 100, máx 500); ao truncar, inclui aviso. Para maior/menor/média/mediana/distribuição/ranking ('quem mais recebeu', 'fornecedor com maior gasto', 'valor mediano') use estatisticas=true (só nos tipos transacoes, empenhos, atos-concessao — os demais não têm coluna de valor): SEM agruparPor = distribuição das linhas (min/máx/média/mediana/percentis) + top/bottom; COM agruparPor = grupos ranqueados por soma decrescente (grupos[0]=maior). A coluna de valor analisada é escolhida automaticamente conforme o tipo; o resultado já traz o rótulo legível dela em campoAnalisado. Registros sem valor são excluídos das estatísticas. Em atos de concessão, cada beneficiário é identificado pelo NOME (cruzado com o cadastro de supridos) e pode-se usar agruparPor='suprido' para ranquear por beneficiário. Informe o ano (a fonte publica de 2013 em diante); use os mesmos códigos administrativos vistos em senado_contratacoes_lista ou senado_execucao_orcamentaria para cruzar gastos.

Input Schema

NameRequiredDescriptionDefault
anoYesAno de referência (a fonte publica de 2013 em diante)
tipoNoQual relação consultar (padrão: supridos)supridos
topNNoTamanho do top/bottom nas estatísticas (padrão: 10)
campoNoOpcional: força a coluna de valor analisada; por padrão ela é escolhida conforme o tipo. Se a opção não se aplicar ao tipo, o padrão é usado automaticamente.
filtroNoFiltro textual (nome, unidade...)
limiteNoMáximo de resultados (padrão: 100)
agruparPorNoOpcional: agrupa e ranqueia os resultados por esta dimensão (as opções válidas dependem do tipo; em atos de concessão, `suprido` agrupa por beneficiário, com o nome).
estatisticasNoDistribuição/ranking sobre as linhas: min/máx/média/mediana/percentis + top/bottom, ou grupos ranqueados por soma via agruparPor. Só para tipo transacoes/empenhos/atos-concessao

Output Schema

NameRequiredDescriptionDefault
provenanceYesBloco de proveniência do portfólio (projeção concise): source, source_url, data_vintage, retrieved_at (horário de Brasília), citation, license, revision e retrieval; field_sources só quando a resposta funde recortes, derived e derivation_note só nos modos de estatísticas. retrieval é o diagnóstico da ida à origem nesta chamada — requisições, tentativas com retentativas, anomalias superadas (timeout, network, rate_limited, http_5xx, http_4xx, malformed_body) e unstable (true quando algo precisou ser repetido) —, ou null quando não foi medido. Lista de blocos quando a chamada consulta várias fontes (índice do search).
attributionYesURLs de origem dos dados (as source_url distintas dos blocos de proveniência, incluindo as de field_sources), para linkar a citação

TDQS

A4.4/5.0
Behavior4/5

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

Annotations already declare read-only/idempotent/non-destructive behavior; the description adds return shape, truncation warning, stats limitations by `tipo`, exclusion of records without values, auto-selected value field, and group sorting semantics. No contradiction.

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-loads the core purpose and return shape, then covers specialized options. It is dense and repeats a few schema details (year range, limit defaults), but the length is justified by the tool's complexity.

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?

For an 8-parameter analytical tool with output schema and annotations, the description covers enough: return structure, filtering, limits/truncation, aggregation, grouping, value-column behavior, source years, and cross-referencing with sibling datasets.

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 baseline is 3, but the description adds meaningful interaction semantics: which types support statistics, how `agruparPor='suprido'` identifies beneficiaries, and how the analyzed value column is chosen automatically.

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/resource ('Suprimento de fundos do Senado') and enumerates the subtypes selected by `tipo`, so an agent can distinguish what this tool returns without opening the schema.

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?

Explains when to use `estatisticas=true` for aggregations and how `agruparPor` changes behavior, plus the 2013+ year source. It does not explicitly compare against all sibling expense tools, but gives clear usage conditions.

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