Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, read-only intent), the description is minimally adequate. However, it lacks any context about return values, error behavior, or the broader workflow, and does not reference sibling tools. It feels terse even for a simple tool, so it does not fully satisfy the completeness criterion.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
