Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no annotations, no output schema, and no parameter details, the description must provide essential context, but it provides almost none. An agent cannot determine what 'export as project' produces, where it writes, what format it uses, or how it differs from the many other export-related sibling tools.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
