var undoCmd = &cobra.Command{
	Use:   "undo",
	Short: "Undo the last action",
	Long: `Undo the most recent mutating action (add, done, delete, modify, start, stop).

The undo stack keeps the last 10 operations. Each undo pops one operation.

Examples:
  opal undo`,
	Run: func(cmd *cobra.Command, args []string) {
		description, err := engine.PopUndo()
		if err != nil {
			fmt.Fprintf(os.Stderr, "Error: %v\n", err)
			os.Exit(1)
		}
		fmt.Println(description)
	},
