Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is complex with polling and two auth modes, but the description covers all essential aspects: what it does, when to use it, how to authenticate, what to expect in the response, and how to handle incomplete results. The output schema exists, yet the description still summarizes the key return fields, making it self-sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
