Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity implied by parameters and sibling tools, the description is incomplete. With no annotations, no output schema, and 0% schema coverage, it fails to provide essential context like usage scenarios, behavioral traits, or parameter details, making it inadequate for effective tool invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
