Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple listing tool with no parameters, the description provides the minimum viable information. However, given the absence of an output schema and annotations, it could be improved by specifying what breakpoint attributes (number, address, hit count, enabled status) are included in the 'structured data'.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
