Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with no parameters, no output schema, and no annotations, the description covers the essential aspects: what it lists, the included fields, and its role in the workflow with get_row. The only minor omission is explicit mention of the output format (e.g., an array) or any response size expectations, but these are not critical for this simple listing operation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
