Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (6 parameters, 2 required, 100% schema coverage, and an output schema exists), the description covers the main aspects: purpose, legal basis, and advanced features. It does not explain return values, but the output schema presumably handles that. No major gaps for a calculator tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
