Vídeos da taquigrafia

senado_videos_taquigrafia

Read-onlyIdempotent

Lista os vídeos e áudios (unidades descritivas) de uma sessão plenária ou reunião de comissão. Retorna { id, tipo, count, total, aviso?, videos } (sessão sem mídia no acervo → count/total 0 com aviso; ao passar de limite inclui aviso). A cobertura de mídia é mais ampla que a das notas: sessões conjuntas do Congresso costumam ter vídeos mesmo sem transcrição, cada item com codigo, data, descricao, orador, duracaoSegundos e os links urlVideo, urlAudio, urlThumbnail. Obtenha o id via senado_agenda_plenario/senado_resultado_plenario (sessão) ou senado_reuniao_comissao (reunião). Para a transcrição textual correspondente use senado_notas_taquigraficas, não esta.

A4.5/5.0

Behavior4/5

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, openWorld), so the description focuses on behavior: the aviso signaling when a session has no media, the aviso when the limite is exceeded, and the fact that media coverage is broader than transcriptions (joint Congress sessions carry video without text). That is genuine added context, though return-format details overlap with the output schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Purpose and routing are front-loaded and waste little, but the middle spends substantial text enumerating the exact return wrapper and every item field (`codigo`, `data`, `descricao`, `orador`, `duracaoSegundos`, URLs) even though an output schema exists, making part of the paragraph redundant.

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 paginated list tool it covers the id source, the tipo distinction, the overflow signal, the empty-media edge case, and the sibling alternative, while the output schema carries the return shape. Nothing an agent needs to invoke 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 the baseline is 3. The description adds meaning beyond the schema by explaining where the required `id` comes from (which sibling tools supply session vs. meeting codes) and by tying `limite` overflow to the aviso field, which the enum/default text alone does not convey.

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?

The opening sentence gives a specific verb ("Lista") plus resource ("vídeos e áudios ... de uma sessão plenária ou reunião de comissão") and even clarifies the domain term "unidades descritivas". It explicitly distinguishes itself from senado_notas_taquigraficas, so an agent can route without opening a 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?

It states the alternative and the condition: use senado_notas_taquigraficas for the corresponding text transcription, not this. It also gives the prerequisite routing for the required id (senado_agenda_plenario / senado_resultado_plenario for sessions, senado_reuniao_comissao for meetings), leaving no inference needed.

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