Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity (single required parameter) and the presence of an output schema (implied by 'Has output schema: true'), the description is reasonably complete. It covers the purpose, parameter details, return format, and error handling. However, with no annotations, it could benefit from more behavioral context (e.g., read-only nature, data source). The output schema means the description doesn't need to explain return values in detail, so this is adequate for the context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
