WHY IT NEEDS A POLICY

Why vaultit_sync needs a policy

In the context of a session continuity/state management server, 'sync' typically means pushing or pulling state data to align two systems, which constitutes a Write operation. However, with no description available, confidence is low. Sync could range from a read-only status check to a write that updates session data across agents.

From the tool's definition Tool name 'vaultit_sync' — description is empty and uninformative.
