Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (multi-country, multiple data types, legal references), the description is complete enough to set expectations. It covers scope, coverage, and performance. It does not detail edge cases or coverage limitations, but an output schema exists, and the schema itself documents async behavior, so the description is sufficient for initial selection.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
