Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, no output schema, no annotations), the description is minimally adequate. It tells the agent what the tool does, but it does not specify expected return values, error conditions, or any prerequisites. For a deletion operation, this is a notable gap, but the tool is simple enough that the description is not severely lacking.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
