Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given that there is no output schema, no annotations, and only two parameters, the description is completely inadequate. It does not explain what boards are, how they relate to the user handle, or what the response contains, making it impossible for an agent to understand the tool's purpose or expected behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
