Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the description covers key aspects (product, length, delivery, price), it does not explain what the agent receives (e.g., confirmation, email delivery) or any steps required from the user. With no output schema, this gap reduces completeness. Sibling context helps but not fully.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
