Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite the tool's simplicity (single required parameter, no output schema), the description is incomplete for a mutation operation. It lacks any mention of permanence, reversibility, permissions, or related data impact. Without annotations, the agent has insufficient context to safely invoke the tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
