I believe that's mostly for fun. Coding agents wouldn't need to interact via the same interfaces humans use, they'd be given a tool to read and write files and they'd be fine with that.
In short, it's developing in the wrong direction.
I switched from Mathematica to Matlab in my work; it was the best investment of time in the entire project
I've been trying that with smaller models and had to make some adjustments (e.g. they all really wanted to include the filename twice). So I just make a small tweak and bam suddenly I can edit code with small fast cheap models.
