Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
An output schema exists, so the description need not enumerate return fields. It covers the important contextual aspects: match scope, in-play/final status, data families, coverage variability, omission policy, and plan requirement, making it complete for the tool's complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
