Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 3 required parameters with zero schema descriptions, no output schema, and no annotations, the description is insufficient. It does not explain what the tool returns, the nature of delivery_claim, or how to obtain the setup_token, leaving critical gaps for correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
