Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of output schema, no parameter descriptions, and no behavioral annotations, the description is incomplete. Even for a simple list tool, it should clarify what 'type names' are, what the return format looks like, and how session_id relates to the operation. The current description leaves critical gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
