Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity, rich annotations, complete parameter schemas, and presence of an output schema, the description is sufficiently complete. It covers what the tool does, the main data included (status/progress, signed URLs), and the single-record mode. No additional context is necessary.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
