Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a destructive tool with no annotations and no output schema, the description is too minimal. It does not mention success/failure behavior, error conditions, or whether the deletion is permanent. The sibling tools include preview delete operations for other resources, but no such preview exists for groups, so the description should clarify the immediate effect.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
