Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the main success and failure states, but it only addresses 'all connected' vs. 'credentials missing,' leaving partial connection states ambiguous. Despite this, with no parameters, no output schema, and strong annotations, the description is nearly complete for a simple read-only tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
