Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of retrieving seasonal statistics (likely involving multiple data points), no annotations, 0% schema coverage, and no output schema, the description is incomplete. It doesn't provide enough information for an agent to understand what statistics are returned, how to interpret parameters, or behavioral constraints, making it inadequate for effective tool use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
