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

TableJSON Schema

Name	Required	Description	Default
`ano`	Yes	Ano de referência (a fonte publica de 2013 em diante)
`tipo`	No	Qual relação consultar (padrão: supridos)	supridos
`topN`	No	Tamanho do top/bottom nas estatísticas (padrão: 10)
`campo`	No	Opcional: 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.
`filtro`	No	Filtro textual (nome, unidade...)
`limite`	No	Máximo de resultados (padrão: 100)
`agruparPor`	No	Opcional: 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).
`estatisticas`	No	Distribuição/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

A4.6/5.0

Behavior5/5

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

Annotations already cover the safety profile (readOnly, idempotent, openWorld, non-destructive), and the description adds substantial behavior beyond them: truncation returns an `aviso`, rows without values are excluded from stats, the analyzed value column is auto-selected per `tipo` and reported as `campoAnalisado`, and stats are unavailable for tipos lacking a value column.

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 the core purpose, then layers the stats/grouping behavior. Dense and backtick-heavy, but nearly every clause carries actionable information; minor tightening of the export/return-shape restatement would help.

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, enum-heavy tool with an output schema, the description covers tipo-driven behavior, stats eligibility, grouping semantics, truncation signal, and year range (2013+), leaving nothing an agent needs to call it correctly.

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 the baseline is 3, but the description adds cross-parameter meaning the schema cannot: which `tipo` values support `estatisticas`, that `agruparPor='suprido'` ranks by beneficiary name in atos de concessão, and the default/labeling behavior of `campo`. This genuinely reduces misuse risk.

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 — annual relationships of fund advances (supridos, atos de concessão, empenhos, movimentações, transações) selected via `tipo` — and differentiates itself from `senado_contratacoes_lista`/`senado_execucao_orcamentaria` by naming them as cross-referencing sources. An agent can tell what this returns and how it differs from siblings.

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?

Gives explicit conditional guidance: use `estatisticas=true` only for tipos `transacoes`/`empenhos`/`atos-concessao`, choose `agruparPor` to rank groups, and cross-reference codes with sibling tools. It does not spell out a when-not-to-use-this-tool case, but the conditional conditions are clear.

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