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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds useful behavioral context beyond annotations by specifying the HTTP GET method and the bulk execution capability through the ids parameter. This provides concrete operational detail without contradicting the annotations.

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 concise and well-structured: the first sentence states the verb, resource, and endpoint; the second adds the important bulk-support behavior. There is no filler or repetition of what the annotations already communicate.

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 simple read operation with strong safety annotations, the description is minimally adequate. However, it lacks explanation of query and account parameters, does not describe the return shape (no output schema exists), and gives no guidance on when to prefer list vs get. These gaps make it incomplete for fully reliable invocation.

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 for the lack of parameter documentation. It only clarifies id via the endpoint placeholder and ids as a batched-execution list. The query and account parameters are completely unexplained, leaving the agent without enough guidance on how to populate them.

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 clearly states the tool's purpose: 'Visualizar' (view) with the specific endpoint GET /api/atributos_financeiros/{id}, identifying the resource as 'Campos extras financeiros'. It is immediately distinguishable from sibling tools because it explicitly indicates a single-resource GET operation, while siblings like list/create/delete/update are clearly different.

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 description implies usage: use this tool to view a specific financial extra-fields record by ID, and mentions bulk support via ids. However, it does not explicitly contrast with alternatives such as gestaoclick_atributos_financeiros_list for listing all records, nor does it state when not to use this tool.

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