Votações em comissão

senado_votacao_comissao

Read-onlyIdempotent

Lista votações em comissões. O parâmetro por (padrão comissao) define o eixo da consulta: por: comissao → exige siglaComissao; lista as votações daquela comissão. por: senador → exige codigoSenador; lista os votos do senador em comissões (filtro opcional comissao). por: materia → exige sigla, numero e ano (ex.: PL 2630/2020); lista as votações da proposição em comissões (filtro opcional comissao). Em todos os casos aceita período opcional dataInicio/dataFim (YYYYMMDD, filtrado pela data da reunião) e retorna { por, ...contexto, count, votacoes }, cada votação com codigo, data, comissao, reuniao, materia, descricao, totais publicados pela fonte (totalSim/totalNao/totalAbstencao; contados dos votos, com placarComputado: true, só quando a fonte não os traz) e votos (senador, partido, voto). Sem paginação. Períodos amplos podem estourar o tempo-limite da consulta (erro de timeout): prefira janelas de até 3 meses e divida períodos maiores em chamadas sucessivas. Obtenha siglas via senado_listar_comissoes, codigoSenador via senado_listar_senadores; para votações no plenário use senado_votos_materia. Atenção: o codigo de cada votação de comissão pertence a um espaço de numeração próprio e NÃO é válido em senado_obter_votacao (que é exclusivo de plenário) — podem coincidir numericamente, mas apontam para votações diferentes.

`sigla`	No	Sigla do tipo da proposição (obrigatório quando por=materia; ex: PL, PEC)
`numero`	No	Número da proposição (obrigatório quando por=materia)
`dataFim`	No	Data fim (YYYYMMDD)
`comissao`	No	Sigla da comissão para filtrar (por=senador ou por=materia)

Output Schema

Name	Required	Description	Default
`provenance`	Yes	Bloco 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).
`attribution`	Yes	URLs de origem dos dados (as source_url distintas dos blocos de proveniência, incluindo as de field_sources), para linkar a citação

A4.8/5.0

Behavior5/5

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

Goes well beyond the readOnly/idempotent annotations: it discloses no pagination, a concrete timeout failure mode with a recommended <=3-month window and split-call strategy, and the placarComputado fallback behavior when the source omits totals. It also warns about the divergent code namespace for committee votacoes — exactly the kind of trap an agent needs surfaced.

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?

The text is dense and front-loaded: purpose first, then a per-axis breakdown, then return shape, then operational caveats. It runs long, but nearly every clause carries actionable information (requirements, return fields, timeout guidance, code-space warning), so little is wasted.

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 a 9-parameter, three-mode tool with conditional requirements, the description covers enumeration of modes, required/optional params, return shape, and operational limits — everything an agent needs to call it correctly. An output schema exists, yet the field rundown still adds value without redundancy.

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 genuine value by consolidating the conditional requirements per axis (which params are mandatory or optional for each por value) and by giving a concrete example (PL 2630/2020) and the date-filter semantics (filtered by meeting date). It does not explain the numeric bounds of ano/numero, but the schema already does that.

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?

Opens with a specific verb+resource ("Lista votações em comissões") and then decomposes the tool into three distinct query axes with the parameters each one requires. It explicitly distinguishes itself from plenary siblings (senado_votos_materia) and from senado_obter_votacao, so an agent can route correctly without opening a schema.

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?

Gives explicit when-to-use rules per axis (por=comissao/senador/materia with their required params), names the prerequisite lookup tools (senado_listar_comissoes, senado_listar_senadores), and states the alternative for plenary votes (senado_votos_materia). It even flags the pitfall of reusing committee votacao codes in senado_obter_votacao.

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