Reuniões de comissão

senado_reunioes_comissao

Read-onlyIdempotent

Lista reuniões de uma comissão (pela sigla) num intervalo dataInicio/dataFim (YYYYMMDD) de até 30 dias; sem datas, usa os últimos 14 dias. A fonte só entrega 30 dias por pedido (e cortava o resto calada), então janelas maiores são recusadas: divida períodos longos em chamadas de até 30 dias. A agenda é lida um dia por vez; um dia que a fonte não entregar aparece em diasNaoLidos, com aviso. Retorna { sigla, periodo, count, reunioes, agendaPrevista?, diasNaoLidos?, aviso? }, cada reunião com codigo, descricao, data, hora, local, tipo e situacao. reunioes traz só as de até hoje; quando o período chega ao futuro, as marcadas para depois de hoje vêm à parte em agendaPrevista (count, reunioes, aviso) — são previsão e podem mudar. Descubra a sigla via senado_listar_comissoes; use o codigo retornado em senado_reuniao_comissao para os detalhes da pauta.

Input Schema

Name	Required	Description
`sigla`	Yes	Sigla da comissão
`dataFim`	No	Data fim (YYYYMMDD); no máximo 30 dias depois do início
`dataInicio`	No	Data início (YYYYMMDD)

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 past the annotations (which only declare read/idempotent/open-world): it discloses that the upstream source silently truncated windows beyond 30 days, that oversized windows are now rejected, that the agenda is read one day at a time, and that unread days surface in `diasNaoLidos` with `aviso`. It also explains the today/future split and that `agendaPrevista` entries are provisional and may change.

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 purpose and the 30-day constraint before return-shape detail, and nearly every clause carries operational weight. It is a dense single paragraph, slightly long, but not padded.

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?

Although an output schema exists, the description still supplies the non-obvious semantics it cannot express: the day-by-day read model, `diasNaoLidos`/`aviso` as a degraded-data signal, and `agendaPrevista` as a provisional future bucket. Nothing an agent needs to call or interpret this tool correctly is missing.

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 meaning the schema omits: the no-dates default of the last 14 days and the operational consequence of the 30-day constraint (split the range). It reinforces YYYYMMDD format, which the schema already carries.

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 and resource ("Lista reuniões de uma comissão") and scopes it by `sigla` and a date interval. It is clearly distinguishable from the sibling `senado_reuniao_comissao`, which it explicitly designates as the details/pauta tool.

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 operating rules: default window of the last 14 days when no dates are supplied, hard 30-day ceiling, and the instruction to split longer periods into multiple calls. It also routes the agent to `senado_listar_comissoes` to discover `sigla` and to `senado_reuniao_comissao` for agenda details.

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