Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity (simple list operation, two parameters, no output schema), the description is mostly sufficient. It states what the tool does and implies the return is a list of draft comments. However, the lack of an output schema means the description could have clarified the return format or any limitations (e.g., pagination), but this is not critical for such a straightforward operation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
