Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with only three parameters and no output schema or annotations, the description is minimally adequate: it names the dataset, the ordering basis, and the high/low choice. However, it lacks details about default limit values, output shape, and edge-case behavior, which an agent might need when invoking the tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
