Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (5 params, nested object, output schema), the description covers purpose, inputs, and output format. It does not explain the async parameter or return values in detail, but the output schema exists and annotations fill gaps, making it nearly complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
