Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the tool's purpose, inputs, outputs, and use cases. It does not explain the async parameter, but that is detailed in the schema. The output schema exists, so return values are well-defined. Minor ambiguity about whether 'daily alerts' implies a push model, but overall it is adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
