Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With full schema coverage, an output schema, and annotations covering read-only/destructive/idempotent behavior, the description fills the remaining gaps by noting token invalidation and retry semantics. It is complete for an agent to call correctly, though it could have named the sibling rotation tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
