Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple delete operation with one fully documented parameter, the description is minimally adequate. However, given that it is a destructive mutation with no annotations and no output schema, it lacks context about permanence, return values, or failure modes, making it not fully complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
