Detalhar processo

senado_obter_processo
Read-onlyIdempotent

Obtém detalhes completos de um processo legislativo específico pelo seu id. Retorna um objeto com id, codigoMateria, identificacao, sigla, numero, ano, objetivo, ementa, tipoConteudo, dataApresentacao, autoria, indexacao, urlDocumento, tramitando (boolean) e o estado atual do processo: situacaoAtual (+siglaSituacaoAtual/dataSituacaoAtual), deliberacao (data, tipo, destino) e normaGerada (quando o processo virou norma). Obtenha o idProcesso antes via senado_search_processos ou senado_buscar_materias; para emendas, relatorias ou prazos use senado_processo_detalhe (parâmetro secao).

TDQS

A4.1/5.0
Behavior3/5

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 fully covered by structured data. The description's added behavioral value is limited to enumerating returned fields, which overlaps the existing output schema rather than disclosing new traits like auth needs or rate limits. Adequate but not additive.

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 purpose and followed by an efficient routing sentence. The long enumeration of ~15 return fields is somewhat redundant given an output schema exists, but it is structured and the final clause earns its place by preventing misuse of a sibling tool.

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 single-param read tool with full schema coverage and an output schema, the description covers the essential precondition and the sibling boundary, which is what an agent needs to invoke it correctly. The return-field list is redundant with the output schema but not harmful.

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 coverage is 100% for the single param and the schema already documents 'ID do processo legislativo'. The description adds the precondition that idProcesso must be obtained from a search tool first, which is useful context, but no format or value semantics beyond the schema. Baseline 3 is appropriate.

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?

Specific verb ('Obtém detalhes completos') plus resource ('processo legislativo específico pelo seu id') and it explicitly names the sibling it is NOT for emendas/relatorias/prazos. An agent can distinguish this from senado_processo_detalhe without opening either 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?

States the prerequisite workflow explicitly ('Obtenha o idProcesso antes via senado_search_processos ou senado_buscar_materias') and routes to the correct alternative with its discriminating parameter ('para emendas, relatorias ou prazos use senado_processo_detalhe (parâmetro secao)'). When-to-use, how-to-obtain-the-id, and the alternative are all covered.

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