Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has an output schema, so return values need not be described. However, the description does not mention ordering, filtering, or default limits, which are common for list operations. Despite this, the simplicity of the no-parameter interface makes the description mostly adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
