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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the bar is lower. The description adds the bulk-execution trait ('accepts ids for batched execution'), which is useful, but it omits details like return format, error behavior, and how query/account factor into execution.

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

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

The description is two compact sentences with no filler: the endpoint and bulk behavior are communicated efficiently. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 4 undocumented parameters and no output schema, the description is too thin. It does not explain the roles of query and account, the return shape, or batch behavior details, leaving the agent to guess beyond the obvious single-ID case.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

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

Schema description coverage is 0%, so the description must compensate. It only adds meaning for the ids parameter ('accepts ids for batched execution'); the required id is left implicit, and query and account are entirely unexplained.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Visualizar') and resource ('Notas Fiscais de Serviços') with a concrete endpoint (GET /api/notas_fiscais_servicos/{id}), clearly distinguishing it from sibling list/create/update/delete tools. The bulk-support note further defines scope.

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

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

The endpoint and 'Visualizar' imply this retrieves service invoices by ID, but the description does not explicitly say when to prefer this over gestaoclick_notas_fiscais_servicos_list, nor does it clarify when to use id vs ids. Usage context is implied rather than stated.

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