Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers purpose, cost, auth, output, and expected response. However, with an output schema present, return values are not the main gap. The missing parameter semantics (especially what 'where' does) leave the tool incompletely specified for callers, so overall completeness is only adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
