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

Annotations declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safe, read-only nature is already covered. The description adds the HTTP method (GET) and resource path, which is mild added context. It doesn't mention pagination, filters, or output shape, but for a list with annotations covering the safety profile this is acceptable.

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 one short, readable line with the operation and endpoint. It earns its place and front-loads the verb. It is minimal to the point of being thin, but it is not padded.

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?

Given the large sibling set and zero parameter descriptions, the description is too thin. It does not clarify what 'arquivos' means in this domain, what query/account filter, or whether authentication is required via the authenticate tool. An agent can guess a basic listing call but has no context to handle edge cases or distinguish from similar list tools like superlogica_impressoes_list or superlogica_documentos_create.

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%, and the description does not explain what 'query' or 'account' mean. The description only says 'listar arquivos' but gives no parameter context beyond the schema's bare names. Since the schema provides no descriptions and the description does not compensate, an agent receives almost no guidance on how to populate these parameters.

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 clear verb and resource: 'Listar arquivos' (list files) via GET /arquivos/index. However, it doesn't explicitly differentiate from siblings like superlogica_arquivos_create or superlogica_arquivos_etiquetas; the 'list' verb distinguishes it partially, but the description doesn't call out its scope within the arquivos domain.

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?

There is no explicit guidance about when to use this tool versus alternatives. The siblings include many arquivos operations, but the description merely names the endpoint. It implies a listing use case but provides no exclusions or conditions for when a different tool (e.g., create, put, add/remove tag) should be used.

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