Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema and no annotations, the description is very incomplete for an agent. It does not specify what the returned data looks like (e.g., an array of status page objects), any limitations (e.g., only active pages), or whether pagination is needed. For a simple list tool, some expectation of response structure would be helpful, but it is entirely absent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
