Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the existence of list_bids, get_bid, place_bid, and withdraw_bid as siblings, the description is incomplete: it does not differentiate this tool from related ones, explain status/limit/offset semantics, or describe the return shape. With no output schema and no annotations, an agent would need to make assumptions or look elsewhere for essential context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
