Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the essential lifecycle for a high-stakes financial tool: hire, escrow, funding, execution, and result return. It could be slightly more explicit about the irreversibility/actual-spend implications, but the annotations already signal destructive behavior and the output schema covers return shape, so the overall picture is adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
