Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a 0-parameter tool with no output schema, the description is minimally adequate but lacks completeness. It doesn't explain what 'status' entails (e.g., pending, rendering, completed) or the return format, which is important given the rendering context and sibling tools that modify the queue. With no annotations, more behavioral context would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
