Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple (one param, no output schema, no annotations), and the description covers the core functionality. However, it lacks details about the return format, what happens if the node lacks a ShaderMaterial, or any edge cases. Given the absence of annotations and output schema, the description could be more complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
