Making Time to Understand

Coding agents increase the amount of work I can take on and the speed at which that work can finish, but they can also create changes faster than my ability to understand their consequences. That creates a strange asymmetry. I can move a system forward very quickly while my own mental model of it begins to lag behind. The same agents can help close that gap, so I have started moving more deliberately between building and understanding. I might spend a period pushing the system forward, then stop and ask the agent to explain what changed, how those changes relate to the rest of the system, and whether the picture I have in my head still corresponds to what is actually there.

I do not need to carry the entire codebase in my head, but I do need to notice when I am acting beyond the limits of what I properly understand. The important measure is not whether I know everything. It is whether the gap between what I can change and what I can reason about has become large enough to matter.

The difficulty is that a working system gives you very little reason to stop. When nothing is obviously broken, understanding is easy to defer. Stopping to understand adds its own trap, since once I start asking questions about an unfamiliar part of the system, there is almost no natural end to the inquiry. Knowing when to stop building and inspect, and when to stop inspecting and build again, becomes a skill worth tuning. The discipline lies in calibration, allowing the system to move quickly without letting my own understanding drift so far behind that I am no longer making informed decisions about what comes next.

The emotional signature is useful here as well. I try to be intentional about not holding tension around the many unknowns in my system because I have baked in a cadence for consistent understanding that will compound over time. The presence of the habit, paced and practiced consistently, is what gives me peace of mind. Understanding is part of the day's allocated energy, not just an intention I hope to get around to. This is not a new problem, but it is definitely more clearly visible than ever before.
