Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the absence of annotations, a 0% schema description coverage for parameters, and the presence of multiple math-related sibling tools, this description is too sparse. It does not explain the expected expression syntax, whether multiple forms are returned simultaneously, or how it differs from similar tools. The output schema exists, but that does not compensate for the lack of usage context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
