Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (destructive operation with recovery), rich annotations (e.g., destructiveHint, idempotentHint), and the presence of an output schema (implied by 'Returns: Confirmation message'), the description is complete. It covers purpose, usage, behavioral nuances, and parameters adequately without needing to detail return values.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
