Should I keep input and output separate when doing AI-assisted content generation in Nushell

It depends.

When creating a complex piece of content from many sources, it is often best to keep input in one Nushell table and place the output in another.

When creating many smaller and simpler pieces of content it is often much more efficient to place the output as separate columns in the input table. In many of these cases the input and the output will naturally belong on the same row.

For more complicated workflows that do not fit into either of the aforementioned categories, you may in some case benefit from joining input and output tables in various ways.

In general, it is best to have a simple workflow that you can easily comprehend and navigate. You do not want too many interconnected moving parts in different places.
