Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (many query parameters, nested path/query objects, no output schema, no annotations), a 3-word description is grossly incomplete. The agent has no information about accepted filters, return shape, pagination, or the required 'format' path parameter, making correct invocation unlikely.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
