Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple delete tool with two parameters and no output schema, the description is minimal but adequate. It does not specify return behavior, error conditions, or consequences of deletion, which a more complete description would include. However, given the tool's simplicity, it meets a baseline level of completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
