Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema and annotations, the description covers the essential context: search criteria, return contents, variability, and post-search workflow. It does not explain edge cases or error behavior, but that is not critical for this search tool. Overall, it is sufficiently complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
