Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations or output schema, the description should provide sufficient context for correct use. It only states the basic purpose and one parameter, omitting details about the response contents, optional fields parameter usage, and any constraints (e.g., case sensitivity, existence guarantees). This is insufficient for a tool within a large set of sibling operations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
