are wonderful at rapidly implementing plenty of code. Nonetheless, if you happen to’ve ever labored rather a lot with coding brokers, you’ll discover they begin struggling after some time. Possibly you’ve spent just a few days writing code with AI. Every part went completely and quick, and then you definitely begin noticing the duties take longer, and the AI is making increasingly more errors.
This can be a clear signal that it’s good to begin refactoring the code. I consider that refactoring your codebase goes to be normal after you’ve applied plenty of code with coding brokers. Coding brokers do make errors and don’t write excellent code. Additionally, if you happen to don’t observe finest practices in current code, the AI will proceed not following finest practices within the new code it generates. Thus, it’s good to constantly refactor your repositories.
On this article, I focus on know when it’s good to refactor your code, what the indicators are, and do it successfully utilizing Claude Code or different coding brokers.
Why refactor your code?
Initially, I all the time wish to cowl why you must care concerning the subject I’m discussing. Refactoring the code appears like a boring activity, and in actuality, it was a really boring activity that you simply needed to do once in a while. Just some years in the past, people needed to manually go into the code repository to search for what wanted to be refactored and begin refactoring the code.
This could sometimes occur as soon as, simply after plenty of implementations within the code, as a result of code naturally drifts away from an ideal state right into a messier state just by individuals interacting with the codebase and dealing on it. This occurs even when people are engaged on it or if AI brokers are engaged on the codebase.
You’ll want to refactor your code as a result of if the code is messy, it merely takes extra time to do implementations, and also you’re extra vulnerable to errors.
Let me give a particular instance. Let’s say we’ve got a chatbot design implementation in your software the place customers can write to an AI bot and get a response again. That is mainly only a chat field area the place you present the AI responses and the consumer responses. code base would guarantee that you’ve got a single element that’s referred to as chat, and this element is utilized in all of the completely different locations within the app the place you show the chat. A poorly designed code base would have one model of this chat per completely different location within the app.
The issue then happens when you need to make a change to the interface of the chat. For instance, you need to replace the colour of the chat field or the icon of the AI. Naturally, you’d need to replace this all over the place within the app the place you show a chat, however that signifies that a human or AI enhancing the code has to edit the code in a number of completely different locations.
If the code, nonetheless, was written properly, you’d solely need to replace the code in a single single location as a result of that’s a centralized code for a way the chat ought to look. That is only a easy instance of how well-written code could make implementations simpler and fewer vulnerable to errors.
When to refactor your codebase
Firstly, I’ll cowl when you must refactor your codebase and what indicators you ought to be in search of.
To place it merely, you must refactor your code when the coding brokers have gotten slower at making implementations and if you begin noticing the brokers creating extra bugs throughout an implementation. Should you see points showing in sudden locations, or in code you didn’t contact, it’s a clear signal that you must begin refactoring.
Moreover, I like to recommend you begin refactoring earlier moderately than later. In fact, working with code that wants refactoring takes extra time and is extra vulnerable to errors, nevertheless it’s additionally very irritating since you’ll discover that you simply begin making modifications, and the coding brokers aren’t capable of do precisely what you inform them to do.
There’s by no means a set time when this want for refactoring is available in. It doesn’t essentially occur after x quantity of days or x quantity of strains of code written. It’s extra of one thing that simply occurs over time. The necessity for refactoring merely occurs after plenty of work has been carried out on a repository.
My concept is that this occurs as a result of some small piece of code begins to float away from the best state, which might occur for a lot of completely different causes. Additional work on this identical space of the code will amplify the results of the drift, and after some time, it is going to be noticeable when the coding brokers or people are much less capable of write the code there successfully.
In fact, you must attempt to keep away from this as a lot as you possibly can; nonetheless, I do consider that refactoring isn’t one thing you must try to fully remove. I consider it’s a pure a part of the evolution of a codebase. It’s best to as a substitute simply embrace the truth that you’ll need to carry out refactoring once in a while, and you ought to be conscious of the indicators for when you must begin refactoring your code.
Easy methods to refactor code with Claude Code
Now that when you must refactor your codebase, I’ll begin discussing refactor your codebase with Claude Code or any coding agent that you simply choose.
There are just a few easy guidelines that I observe every time I begin refactoring.
Use probably the most superior and high-effort reasoning you possibly can. Refactoring is a activity that requires plenty of intelligence, and also you don’t need to make errors right here. For instance: Use the workflows characteristic from Claude Code, or xhigh pondering on GPT-5.5
Solely carry out one refactoring at a time in your repository. It’s okay to refactor whereas doing different implementations as properly, however you don’t need to have a number of refactoring duties working directly
In case you are not sure of the optimum folder construction, examine or give the coding agent entry to a different code repository with an excellent construction that you simply like, and inform it to mimic that
Refactoring takes time. Simply have it as a activity you run within the background whereas engaged on different stuff
Normally, after I begin refactoring code, I take advantage of the next setup: I open my Claude Code in a brand new worktree within the repository, and I spin it up with the very best effort out there in Claude Code, which is Ultracode.
If I do know what to refactor, I inform Ultracode and Claude as a lot data as potential on what to refactor and why to refactor it. You would possibly assume that mentioning the why isn’t mandatory, and in some instances, it’s not, however I discover it actually helpful as a result of then the AI is knowing why I’m doing what I’m doing, which helps it align with what I need to implement.
I then give the agent plenty of time to undergo the whole repository, particularly the half I need to refactor, and give you an in depth plan on refactor. I do that in plan mode in Claude Code.
I then learn by way of the plan to make sure it’s as I anticipate. Normally, the brokers are higher at refactoring than I’m personally, so I discover that the plans are normally okay on the primary try.
An essential a part of the immediate that I take advantage of every time I carry out refactoring is that I inform the mannequin to implement exams that it ought to run earlier than and after. The exams ought to, after all, work beforehand, and they need to, after all, all work once more when it’s carried out. This helps the mannequin confirm its work and guarantee it doesn’t introduce any new bugs when performing refactoring.
I’ve carried out plenty of refactoring utilizing Claude Code, and I might say it’s nearly excellent at performing refactoring work. After I used the setup I described above, I very hardly ever skilled any points, and it nearly all the time had a major enhance in how properly the coding brokers had been capable of run in my repository.
Merely put: Refactoring code with Claude Code may be very efficient.
Conclusion
On this article, I mentioned refactor code utilizing Claude Code. I mentioned why you must care about refactoring, highlighting the way it could make your coding brokers far more efficient at implementations within the code repository. I then coated know when it’s good to refactor and refactor the code, that are the 2 most essential factors you must know in terms of refactoring.
With AI and coding brokers, I consider refactoring code is one thing you must merely do constantly in your code repository. It’s best to usually have an agent undergo your code, examine if something wants refactoring, and begin refactoring immediately. Normally, the agent will have the ability to do that absolutely by itself, and you’ll not need to observe up a lot with it, however it is extremely easy to do. It’s one thing you must constantly do to make coding brokers as efficient as potential in your repository.
