Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the output schema exists, annotations are present, and the input schema is well-documented, the description covers the essential aspects: purpose, frameworks, and data source. It could mention the return format or pagination behavior, but the output schema likely covers that, making the description sufficiently complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
