Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of output schema and annotations, the description does not explain return values, success conditions, or error cases. For a simple restoration tool, more context (e.g., what happens to the item after restore, constraints like only items you have permission to restore) would be beneficial.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
