Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With a nested input schema and no output schema, the description must compensate by explaining what the export produces (e.g., file download, URL, stream), how format options work, and error conditions. It provides none of this, leaving the tool highly incomplete for effective use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
