Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, no annotations, and a single required parameter, the description must explain both the action and its implications. It only covers the basic action and the confirm requirement, omitting details like error conditions, effect on print history, or what happens if the printer is not paused. For a state-changing tool, this is incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
