Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given there is no output schema, minimal annotations, and a description that provides almost no context, the tool is severely under-described. A planning/pre-flight tool likely has complex behavior, but nothing explains what the plan entails, how it is returned, or what 'safe' means.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
