Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity, annotations, and existence of output schema and sibling tools (cancel/status), the description provides sufficient context for the agent to understand initiation of delayed deletion. It could mention confirmation or next steps, but the sibling tools cover those.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
