# Check the saved-work change watermark

> library_status: permissions and generated input/output contracts.

`library_status` · Gateway release **0.8.3**

Check the exact saved-work page using the same Storyworld, types, search, sort, cursor and limit as library\_search. Compare revision for changes to that page or the matching count. authorizationScope changes require discarding cached results immediately. This is a dated check, not a live subscription or approval, and does not inspect unloaded pages. Always rechecks current membership.

Required scopes: `account:read`, `studio:read`. Read-only.

Availability depends on runtime configuration and the permissions granted to this connection. Use live MCP discovery as the authority.
