The Honeymoon Phase
I spent the first two weeks with Cursor thinking I had found a cheat code. I was hitting Cmd-K, typing a vague request, and watching the code rewrite itself. It felt like I was managing a junior developer who worked at light speed.
Then the bugs started appearing. Not the obvious syntax errors, but the logic gaps. The AI would change a variable type in one file and forget to update the interface in another. Because I was skimming the diffs instead of reading them, I started shipping regressions that I would have caught in five seconds using a traditional editor.
The Trap of the Diff-Review
When you use an AI editor, the primary activity shifts from writing code to reviewing diffs. This is a dangerous shift if you are not careful.
Reviewing a diff is cognitively different from writing the logic. When you write code, you are building a mental model of the data flow. When you review a diff, you are often just checking if the code looks right. This is where the "hallucination creep" happens. The AI suggests a change that looks elegant, fits the pattern of the project, and passes the initial test, but misses an edge case that only happens in production.
A Better Workflow
To stay in control, I had to change how I interact with the tool. Here is the system I use now to ensure I actually understand what is being added to my repo.
1. The Pseudo-Code Prompt
Instead of asking the AI to "implement the payment logic," I now prompt it with the logic steps I want.
Example: "Create a function that takes the cart object, validates the stock levels via the API, calculates the tax based on the user's state, and returns a final total. Use the existing TaxCalculator class."
By defining the steps, I am still the architect. I am not delegating the thinking, just the typing.
2. Small Atomic Changes
It is tempting to highlight 100 lines of code and ask for a refactor. Do not do this. The larger the change, the more likely the AI is to omit a crucial line of logic or introduce a subtle bug.
I now limit my AI edits to small, atomic chunks. If a feature requires five changes, I do five separate prompts. This makes the diffs manageable and the reverts easy.
3. The "Explain it Back" Rule
Whenever the AI suggests a complex block of logic that I did not explicitly dictate, I ask it to explain why it chose that specific approach. If the explanation sounds generic or doesn't make sense, I delete the code and write it myself. If you cannot explain why a piece of code is there, it does not belong in your codebase.
The Danger of Context Overload
AI editors have access to your entire folder. While this is great for finding where a function is defined, it can lead to "context pollution."
Sometimes the AI sees a deprecated pattern in an old file and decides to replicate that pattern in your new feature because it thinks that is the project style. I have found that manually adding only the relevant files to the context window is far more effective than relying on the automatic index. It forces you to think about the dependencies of the feature you are building.
The Takeaway
AI editors are tools for acceleration, not replacement. The goal is to reduce the friction of boilerplate and repetitive patterns, not to stop thinking about how the software works.
If you spend more time clicking "Accept" than you do reading the actual lines of code, you are creating a technical debt bomb that will explode the first time you have to debug a production outage at 3 AM. Keep the architect in the driver's seat and use the AI as a high-speed typist.
