Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity (no parameters, read-only, output schema exists), the description is minimally viable. However, it lacks any context about what IP speed limit rules are, how they relate to other speed-limit tools, or any specific usage scenarios. The presence of an output schema means return values need not be described, but a brief note on when to use this versus list_mac_speed_limits would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
