Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Combined with annotations and an output schema, the description covers the essential decision-making facts: authorization, destructive intent, soft-delete semantics, and confirmation. It does not detail what soft-delete means practically (e.g., whether the item disappears from menus or can be restored), which is a minor gap.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
