Read-onlyIdempotent

Retrieve a Brazilian Federal Senate e-Cidadania legislative idea by ID, including title, description, support count, status, author, deadline, and bill conversion.

Instructions

Obtém o detalhe de uma ideia legislativa do e-Cidadania. Retorna um objeto com id, titulo, descricao (texto completo, truncado em ~2000 caracteres), apoios, dataPublicacao, dataCriacaoEstimada, avisoDatas, status, autor, url e plConvertido (sigla/número quando virou projeto de lei). Datas: dataPublicacao é a DATA LIMITE para receber os 20.000 apoios — a única data que o portal publica; o nome do campo é histórico — e por isso cai no futuro em ideia aberta; dataCriacaoEstimada (= data limite − 120 dias, a regra dos 4 meses do portal) é calculada pelo servidor e é estimativa, não dado da fonte. O campo comentarios vem null: a página de ideia não possui recurso de comentários. Obtenha o id antes via senado_ecidadania_listar_ideias.

A4.4/5.0

Behavior5/5

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

Annotations already carry readOnly/idempotent/destructive, but the description adds real behavioral warnings beyond them: `descricao` is truncated at ~2000 chars, `comentarios` always returns null, and crucially `dataPublicacao` is a future deadline rather than a publication date (a historical misnomer). These prevent concrete misinterpretation of the response.

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-loads the operation, then groups the return fields and uses a bolded "Datas:" block for the tricky semantics. Dense and mostly earned, though enumerating the return object partially duplicates the output schema.

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 resolves the genuinely ambiguous parts (date semantics, truncation, null field, id sourcing) that the schema cannot express. Nothing an agent needs to call it correctly is missing.

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?

With 1 parameter at 100% schema coverage, the schema already defines `id` as the idea identifier. The description only adds where the value comes from (listar_ideias), which is useful workflow context but marginal semantic detail, matching the baseline 3.

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 ("Obtém o detalhe de uma ideia legislativa do e-Cidadania"), and the field list plus the singular "detalhe" framing cleanly separates it from the sibling senado_ecidadania_listar_ideias. An agent can select it without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly names the alternative and prerequisite: "Obtenha o `id` antes via `senado_ecidadania_listar_ideias`." It gives clear entry conditions but no explicit when-not-to-use or contrast against the other obter_* siblings, so it falls just short of 5.

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