Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations, no output schema, and 0 parameters, the description is minimally complete for a basic list operation but lacks details on behavior, output, or context. It meets a bare minimum for clarity but does not compensate for missing structured data, leaving gaps in understanding how the tool functions.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
