Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's mathematical nature, 2 parameters, no annotations, and no output schema, the description is incomplete. It doesn't cover parameter meanings, units, calculation formulas, or output structure (e.g., whether it returns both values as a single object). For a calculation tool, this lack of detail could lead to misuse or incorrect assumptions by the agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
