Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has three required parameters, no output schema, and no annotations, yet the description provides no usage context, no parameter hints, no return-value info, and no behavioral detail. It's the minimum viable statement of what the tool does, but an agent has almost nothing to go on for correct invocation beyond the parameter names.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
