Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (archiving with nested parameters), no annotations, and a rich output schema left unexplained, the description is insufficient. It does not clarify the meaning of archiving, the response structure, or how to handle multiple group requests, leaving critical gaps for an agent to fill.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
