Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema, good annotations, and low complexity (2 parameters, 1 required), the description is mostly complete. It covers the core behavior and exclusions. It could mention prerequisites like domain ownership verification, but that is implied by 'owned by the account.'
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
