So this is probably a bit confusing.

                
Allow me to explain...

                

                
In short, I devised a way to achieve 'Remote Command Execution' on Minecraft
                via setting up 8 simple command blocks in a forever-loaded chunk, and embedding commands in custom_data
                on items. When said item is held in your hand, it runs the command/commands stuffed into the custom_data
                tag. I really only made this because the length of the commands I was putting into an item got annoyingly
                long to have to rewrite into the custom_data section by hand, and figured I'd automate the process to
                save myself some hours. I then take the resulting custom_data value and throw it into the corresponding text box
                on this dope website under the "Extras" section.

                
If for some reason you would like to replicate what I did for fun, I'll leave the commands
                for the 8 command blocks I used to achieve this as well as the orientation of said blocks (Yes it does matter,
                I was lazy and relative positioning was the only way I came up with to handle some issues that came up)
