senado_autores_atuais

Read-onlyIdempotent

Identify parliamentarians and former lawmakers who authored Brazilian legislative processes still in progress, ranked by number of matters, filtered by state or name.

Instructions

Lista parlamentares autores de processos em tramitação, ordenados por produção (maior número de matérias primeiro). Atenção à semântica: 'atual' significa 'com processo AINDA EM TRAMITAÇÃO', não 'mandato vigente' — a lista mistura senadores, deputados e ex-parlamentares, e a mesma pessoa pode aparecer 2× com códigos distintos (ex.: como 'Senador' e como 'Deputado', pelo tratamento); não use como lista de senadores em exercício (para isso, senado_listar_senadores). Retorna { count, total, autores }, cada autor com codigo, nome, tratamento, uf e quantidadeMaterias. Filtros opcionais uf e nome (busca parcial sem acento); limite padrão 50 (máx. 1000). Use o codigo em senado_obter_senador ou senado_search_processos (codigoParlamentarAutor).

A4.8/5.0

Behavior5/5

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive), yet the description adds non-obvious behavior: 'atual' means still-in-progress rather than current mandate, the list mixes senators/deputies/ex-parliamentarians, and the same person may appear twice under different `tratamento`. That disambiguation is exactly the context annotations cannot supply.

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?

A single dense paragraph with essentially no filler — every clause carries semantics, filtering, or routing information. Slightly front-loaded on purpose but the critical semantic warning is pushed into the second sentence rather than leading.

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?

Despite an output schema existing, the description still sketches the return shape ({count, total, autores} with codigo, nome, tratamento, uf, quantidadeMaterias) and enumerates all optional filters and their bounds. Nothing needed to call 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; the description lifts it by adding accent-insensitive partial matching for `nome` ('busca parcial sem acento'), which the schema does not state. `limite` default/max is merely repeated from the schema, so it does not go further.

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+scope ('Lista parlamentares autores de processos em tramitação, ordenados por produção') and explicitly names the sibling it is not (senado_listar_senadores). An agent can select this tool without opening any 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-not ('não use como lista de senadores em exercício') with the correct alternative, and adds downstream routing guidance ('Use o codigo em senado_obter_senador ou senado_search_processos'). Both the selection decision and the follow-up path are spelled out.

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