I think the most important way someone could be able cultivate breadth of understanding as well depth when needed is to be able to truly understand all of the things that are touched when someone uses the system, step by step. This doesn’t require deep knowledge in any one aspect of the system, but it does require someone to be curious, be open, and be willing to put themselves in the users shoes and use the feature, and then switch back into the developers mind and map user action to where in the codebase is being activated and why. And be willing to go back and forth. The interesting thing is that agents can help us, but the exercise loses its value if the agent just maps it out for us. We need to be in the process of discovery in order to build our own mental model.
