Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the tool lacks an output schema, the description lists the types of information returned (costs, talent, tax rates, ease of doing business), giving the agent a reasonable understanding of what to expect. The tool is simple, and the description is adequate for selection and invocation, though it could mention the response format or clarify parameter requiredness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
