Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (4 parameters, no annotations, but with output schema), the description is mostly complete. It covers purpose, behavior, parameters, and returns, though it could benefit from more explicit usage guidelines relative to siblings. The output schema existence means return values don't need detailed explanation, but the description still usefully notes markdown format.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
