Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple, but with no annotations, no output schema, and no parameter descriptions, the description must compensate. It fails to explain what resource is deleted, how item_id is used, or whether the delete is restricted by group or household context. This is inadequate for an agent to invoke the tool confidently.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
