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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safe read-only nature is established. The description adds the GET endpoint and the bank-account domain scope, which is consistent with the annotations, but it does not disclose response shape, pagination, or authentication needs. This is some added context beyond the annotations, but not rich behavioral detail.

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 a single compact sentence, front-loaded with the domain and resource, followed by the endpoint. There is no fluff or redundant explanation, and every phrase contributes to basic understanding.

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?

For a tool with two undocumented parameters and no output schema, the description leaves meaningful gaps: the semantics of query and account, what the response contains, and any filtering or pagination behavior. The domain and endpoint are clear, but an agent still lacks important information needed to invoke the tool correctly in nontrivial cases.

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 the 'query' or 'account' parameters at all. 'account' may be somewhat inferable from the resource, but 'query' is completely opaque. The description fails to add meaning beyond the bare schema property names.

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 uses a specific verb 'Listar' (to list) and a clear resource 'contas bancárias' (bank accounts), and adds the endpoint GET /contabancos/index. This makes the tool's purpose understandable, though it does not explicitly distinguish it from similar sibling list tools such as superlogica_list_accounts or superlogica_caixa_list.

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?

No guidance is given about when to use this tool instead of another sibling list tool, nor about what the query or account parameters should contain. The domain label 'Condomínios / Contas bancárias' implies a bank-account listing use case, but there are no explicit conditions, exclusions, or alternatives.

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