Tabelas de referência de processos

senado_tabelas_processo

Read-onlyIdempotent

Resolve codes and acronyms using Brazilian Senate legislative process reference tables before filtering or retrieving process details.

Instructions

Consulta tabelas de referência do processo legislativo para resolver códigos/siglas, conforme tabela. Domínios de entidade: siglas (siglas de proposição), assuntos, classes, destinos, entes. Domínios de tipo (código→descrição): tipos-situacao, tipos-decisao, tipos-autor, tipos-atualizacao, tipos-documento, tipos-conteudo-documento, tipos-prazo. Retorna { tabela, count, total, linhas } — count é o nº após o corte por limite e total o disponível; count < total indica truncagem (aumente limite); count 0 quando o filtro não casa. Cada linha traz código/sigla e descrição (campos conforme a API). Use antes de filtrar em senado_search_processos/senado_processo_detalhe. Para as tabelas do plenário (tipos de sessão, legislaturas) use senado_tabelas_plenario. Ex.: { tabela: 'tipos-prazo' } ou { tabela: 'siglas', filtro: 'PEC' }.

A4.6/5.0

Behavior4/5

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

Annotations already declare readOnly/openWorld/idempotent/destructive, so safety is covered. The description adds genuinely useful behavior: the return envelope, the truncation semantics (count < total = truncated, raise limite; count 0 = filtro mismatch), and that each row carries code/sigla + description. It stops short of auth/rate context, but adds real value beyond the annotations.

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?

Dense but well front-loaded: purpose and domain split first, then return/truncation semantics, then routing and examples. Slightly long and repetitive with the schema's enum list, but every clause carries usable information.

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 3-param lookup with an output schema and full annotation coverage, the description supplies everything an agent needs: what each domain returns, how to interpret the response counts, when to reach for it, and which sibling to use instead. Nothing material 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 baseline is 3, but the description adds meaning beyond the enum list by conceptually grouping tabela into 'entity' domains vs 'type' domains (código→descrição) and explaining that filtro drives count to 0 and limite drives truncation. This is semantic interpretation the schema hints at but doesn't organize.

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 ('Consulta tabelas de referência do processo legislativo para resolver códigos/siglas'), enumerates the exact domains it serves, and explicitly distinguishes itself from senado_tabelas_plenario. An agent can tell it apart from the sibling reference-table tool 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?

Gives an explicit when-to-use ('Use antes de filtrar em senado_search_processos/senado_processo_detalhe') and a when-to-use-the-other ('Para as tabelas do plenário... use senado_tabelas_plenario'). Alternatives and selection conditions are named, not inferred.

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