Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity, no annotations, and an output schema that documents return types, the description is fairly complete. It covers purpose, parameters, and returns adequately. However, it lacks context on prerequisites (e.g., needing an open mindmap) and doesn't fully explain sibling differentiation, leaving minor gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
