Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a batch creation tool with complex nested parameters (5 sub-properties), no annotations, and no output schema, the description is severely incomplete. It doesn't explain the document structure, required fields, default behaviors, or what the tool returns. The minimal description fails to compensate for the missing structured information.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
