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

TDQS

A4.4/5.0

Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive, so the bar is lower; the description still adds real behavioral context: truncation at limite with an aviso field, compacted autoria plus totalAutores, and the mandatory-filter constraint. Useful additions beyond structured fields.

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 endpoint, then constraints and example. The enumeration of every return field is somewhat dense given an output schema exists, but otherwise the text earns its place.

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?

Covers purpose, mandatory-filter rule, pagination limit, truncation warning, date formats, and the follow-up detail tool, with annotations supplying the safety profile and an output schema covering returns. 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.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline would be 3, but the description adds value with default/max on limite, the date format note (YYYYMMDD or ISO), and a worked example showing filter combinations. Marginal but genuine uplift over the schema.

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 ('Busca processos legislativos no endpoint v3 /processo') and explicitly positions it against sibling senado_buscar_materias as complementary parameters. An agent can distinguish it from the sibling 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 Guidelines4/5

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

Gives a hard precondition ('É obrigatório ao menos um filtro'), routes to senado_obter_processo for details via the returned id, and provides a concrete example call. It lacks an explicit when-not-to-use statement versus senado_buscar_materias, keeping it short of a 5.

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