> I wrote my own CLI to make aspects of my job easier

I mean, according to your employment agreement, that code is owned by your employer, since you wrote it as an employee for use at work. They could easily demand that you share it, if they knew it existed.

This just illustrates that smart people figure out their own productivity/time-saving shortcuts at work, and little scripts and tools like this are part of it. Happens all the time. Other employees don't, and just plod through whatever manual process they were trained to do.
