Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema, 100% parameter coverage, and annotations, the description is fairly complete. It covers the purpose and key behavioral trait ('No human in the loop') but could ideally mention what happens post-claim (e.g., immutability) for full completeness. Still, for the complexity level, it is sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
