Follow-up hints for the notebook tool, keyed off the hint_context maps YmerNode.Mcp.Tools.Notebook.Actions produces. After execute creates schema, the natural next steps are describing or querying it; after a capture the natural next step is confirming it. A completed restore needs no follow-up either, since the roll-back is already done — but a restore that failed recoverably does: the hint carries the id of the backup to restore, or of the restore to retry, so the recovery is one call away instead of a re-read of the error text. Everything else falls through to none — including every answer about a notebook that cannot take the call, whose next action is a person's and not another tool call, and a backup that will not open, whose next action is a different id this module has no way to choose.
