Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given complexity (1 param, 0% schema coverage, no annotations, but output schema exists), the description is complete. It explains input format, behavioral features, and output format (Markdown with metadata, body, references), leveraging the output schema to avoid detailing return values. No gaps remain for effective tool use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
