Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 5 undocumented parameters, no annotations, no output schema, and multiple sibling tools, the two-word description is completely inadequate. It doesn't explain what a 'dataset' is in this system, how results are returned, what filtering options exist, or how this differs from other dataset-related tools. The description fails to provide necessary context for effective use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
