Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given that an output schema exists and annotations are present, the description covers the essential aspects: purpose, input types, output structure, and a key behavioral note (async requirement). It does not mention error handling or pagination, but for a read-only evidence collector, it is reasonably complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
