Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is very simple—one parameter, no output schema, no nested objects. The description and schema together cover the essential semantics of duplicating a whiteboard by ID. Minor gaps remain (e.g., return value, side effects on original), but for this low complexity, the description is largely complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
