Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
An output schema exists, so return values need not be described, and annotations cover the safety profile. Still, for a destructive, self-removal team operation the description omits permission requirements, edge cases (e.g., sole owner leaving), and any coupling to team membership state, leaving it only minimally complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
