Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with only one input parameter, an output schema, and annotations already covering mutability, the description is complete. It covers what happens (archived), how to undo it, and how to view archived items, leaving no important gaps for an agent to call it safely.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
