Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema, the description provides sufficient context: purpose, input, output nature, and usage. It also includes the nuance of commodity-canonical methods. Slightly more detail about the return structure could elevate it, but it is largely complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
