Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity (1 param, no output schema, no annotations), the description is incomplete. It does not describe the output format, any default behavior, or what 'objects' refers to. A list operation typically needs to mention ordering, pagination, or scope.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
