Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, no output schema), the description sufficiently communicates what the tool reads: page size, orientation, and margins. However, it does not specify the return format or structure, but this is not strictly necessary for such a simple getter. The presence of sibling tools like word_set_page_layout provides helpful contrast.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
