Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a read-only quote tool with zero required params and no output schema, the description captures the essential context: purpose, constraints, and non-destructive nature. The missing context is the full ranking behavior, e.g., what 'zero-upfront constraints' means, how the five parameters map to constraints, and whether a quote result is a list or single match. Since there are 5 undocumented parameters and no output schema, there is room for more detail, so this is not a top score.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
