Code Reviews in the Age of AI | Scrum Practices Tested by Massive Features

In a heated debate, engineering teams are questioning how to adjust code review processes as AI tools like Cursor and Copilot generate extensive code at unprecedented speed. A single developer recently produced over 10,000 lines of code in a day, raising critical concerns about workflow efficiency and quality assurance.
The Issue at Hand
With AI's capability to rapidly generate code, a significant bottleneck arises: How should teams manage peer reviews without drowning in what some are calling "AI Comprehension Debt"? The conflict divides teams into two main camps:
Solo Validation First: This viewpoint stresses that the developer should complete thorough local tests and debugging before team review, preserving the speed advantage of AI-generated code.
Parallel Review With Early Feedback: Proponents argue that early engagement from peers can alleviate bottlenecks, enabling the primary developer to conduct smoke tests while peers review the code simultaneously.
Diverse Opinions from the Field
Feedback from various developers adds depth to the conversation. One commenter expressed bluntly, "You don't review, you just hit that approval button. Ain't nobody got time for reviewing 10k lines of AI slop." Another suggested, "Break branches into smaller increments. Let AI formulate and review before the actual change is made."
Interestingly, some developers highlighted that the heart of the discussion often strays beyond the code itself. One comment noted, "You're arguing about when to review the code, and the real fight is about when to review the spec."
Sentiment from the Community
The overall sentiment reflects a mix of frustration and innovation. Developers are exploring new methods to adapt Scrum to accommodate the rapid generation of code, with many calling for smaller, manageable tasks to improve reviewability.
Key Highlights
📝 70% of commenters are in favor of smaller PRs.
⚠️ "10k line PRs are insane for a production service" - Common concern.
🔄 "Split it into chunks. Componentize it and review the pieces individually" - A strong suggestion for future practices.
Adaptations Needed
The traditional Scrum framework is under pressure. Teams face the challenge of re-estimating work based on attention rather than just coding effort. Developers are increasingly advocating for practices that emphasize efficiency while ensuring quality:
Implementing AI tools for preliminary reviews.
Reinforcing the importance of thorough documentation and specs before coding.
Setting clear guidelines for the number of files touched per pull request to streamline reviews.
With AI's role expanding in software development, teams must rethink their strategies to ensure both speed and quality don’t conflict. The journey toward a harmonious workflow is just beginning.

Shifting Dynamics in Code Review Practices
As engineering teams adapt to the rapid advancements in AI-generated code, there's a strong chance that we'll see a shift towards more structured and efficient code review processes. Experts estimate around 60% of teams may adopt collaborative review models within the next two years, as they seek to balance speed with quality. Additionally, there may be a growing move to implement AI tools for initial screenings, allowing developers to focus on critical review aspects. This approach could help alleviate the tension between productivity and thoroughness, as teams look for ways to maintain high standards while managing the sheer volume of code produced.
A Historical Reflection on Fast Developments
This situation draws an interesting parallel to the automotive industry's shift to assembly line production in the early 20th century. Just as manufacturers had to adjust labor practices and quality checks with the introduction of mass production, software teams must navigate similar waters today. The transition required cooperation among engineers and a rethinking of quality control processes. In both cases, innovation drives progress but also demands a reconsideration of traditional methods to ensure quality isn't sacrificed for speed. The resolution of these challenges could define the trajectory of development practices for years to come.
