It is neither of these. It's an application that processes data and is not accessible outside of the companies network. Not everything is an app.

I described my workflow that has been a game changer for me, hoping it might be useful to another person because I have struggled to use LLMs for more than a Google replacement.

As an example, one task of the feature was to add metrics for observability when the new action was executed. Another when it failed.

My prompt: Create a new metric "foo.bar" in MyMetrics when MyService.action was successful and "foo.bar.failed" when it failed.

I review the plan and let it implement it.

As you can see it's a small task and after it is done I review the changes and commit them. Rinse and repeat.

I think the biggest issue is that people try to one shot big features or applications. But it is much more efficient to me to treat Copilot as a smart pair programming partner. There you also think about and implement one task after the other.
