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 no explanation, and the description covers the lifecycle semantics (hold, duration, quota, release). It would be fully complete with a note on supporting permissions or quota-exhaustion behavior, but nothing essential for calling it is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
