Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is very simple: one parameter, no output schema, and annotations already cover safety. The description covers purpose, usage, and tool relationships. It does not mention error conditions or return values, but for a destructive action with idempotentHint, this is a minor gap in an otherwise complete description.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
