Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple delete operation with two parameters and no output schema, the description is reasonably complete. It covers the action, the permanence, and the required inputs. It does not describe the response or error cases, but those are less critical for a basic deletion tool. Given the lack of annotations and output schema, it could have been more detailed, but the essentials are present.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
