Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a no-parameter, read-only GET endpoint, the description covers the basics: endpoint, category, auth scope, and safety. However, there is no output schema, and the description does not describe what the dashboard stats response contains, what time ranges or aggregations apply, or how it differs from other stats endpoints, leaving meaningful gaps for an agent deciding whether this tool satisfies a user request.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
