Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (batch mutation, no annotations, no output schema, two parameters), the description is too thin. It does not explain what 'properties' means in this context, how the batch operation behaves, or why an agent would choose this over specialized setters. The schema compensates for parameter names but not for operational context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
