Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations, no output schema, and sparse parameter docs, the description should compensate by explaining the system identifier, the meaning of rows, and the limit parameter. The sibling context includes several similar get_* tools, and this description does not clarify how get_system fits among them.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
