Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has two parameters, no annotations, no output schema, and many related sibling tools, the description is woefully incomplete. It does not clarify what inputs are expected, what output format to anticipate, or how it differs from similar tools, leaving the agent without sufficient information to invoke it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
