Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (5 parameters with nested objects, 0% schema description coverage, no annotations, no output schema), the description is completely inadequate. A search tool with complex filtering capabilities requires much more context about available properties, filter operators, result format, pagination behavior, and usage patterns to be effectively usable.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
