Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity, the description adequately covers the main return behaviors. There is no output schema, so the description must explain return values, which it does for the two key scenarios. However, it does not elaborate on possible intermediate states (e.g., partial connectivity), but this is a minor gap.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
