If you work with AI long enough, you will eventually run into a frustrating pattern: the code is improving, but the design is getting harder to reason about.
It usually happens one fix at a time.
You start with a real goal. The AI helps you get most of the way there. Then edge cases show up, so you patch those. Then those patches create side effects, so you patch those too. After enough rounds, you may still have working code, but you no longer have a solution that feels clean.
That is the trap.
The real problem
AI is often very good at solving the task in front of it. What it does not automatically do is protect the larger intent of the system unless you explicitly bring that intent back into focus.
That means a series of good local fixes can slowly pull you away from the behavior you were actually trying to create.
This shows up most often when you are:
- working with legacy code
- layering new behavior on top of old behavior
- preserving native behavior while adding modern behavior
- fixing event-order issues
- cleaning up edge cases one by one
The narrower the prompt becomes, the easier it is to lose the whole shape of the system.
The better question
Before you apply one more AI-generated patch, stop and ask:
- Are we still solving the original problem?
- Or are we now fixing side effects created by earlier fixes?
- What behavior is native here?
- What behavior are we layering on top?
- Are these changes cooperating with the design, or starting to fight it?
- Do we need another fix, or do we need an audit?
That last question matters more than most people realize.
Sometimes the smartest next prompt is not "fix this."
Sometimes it is "trace the full sequence and show me where our changes are colliding."
Why this matters
AI can help you move fast.
It can also help you drift.
The danger is not always bad code. Sometimes the danger is good code built around a task that has become too narrow.
That is how you lose the big picture.
From the book
This is one of the recurring patterns I explore in Real Programmers Use AI, especially in the difference between session-based coding and more autonomous AI workflows.
But the practical lesson is simple:
When local fixes start making the system feel more brittle instead of more clear, stop patching and step back.
