Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a destructive action, the description covers the essential behavioral caveats: permanence, workspace-wide impact, permission levels, and the need for user confirmation. Since an output schema exists, return details need not be explained. The combination of schema, annotations, and description gives an agent everything necessary to invoke the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
