Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 10 parameters, all optional, and an output schema is present, the description adequately covers input details, return type, and error handling. It is complete for an agent to understand how to invoke the tool, though it could list possible values for 'action' or 'progress'.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
