Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of output schema, annotations, and parameter descriptions, the description should explain the return value, connection behavior, and scope of 'resource properties.' It provides none of this, leaving critical gaps in the agent's understanding of how to invoke the tool or what to expect from it.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
