Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the zero-parameter schema, readOnlyHint annotation, and presence of an output schema, the description is minimally sufficient to invoke the tool. However, it doesn't clarify the exact semantics of 'issue counts' or hint at when this endpoint is preferred over listing issues, leaving slight contextual gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
