Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity (no parameters, no output schema), the description covers the main return scenarios and key fields. However, it does not explicitly address partial connectivity states beyond 'all connected' and 'credentials missing', which leaves a small gap in completeness. Still, it is sufficient for most use cases.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
