The text discusses the challenges of code reviews in software development, particularly when dealing with large changes. It introduces the concept of "stacked PRs," where smaller, iterative changes are reviewed one by one instead of bundling them into a single pull request. This approach helps maintain the effectiveness of code reviews and reduces the time-consuming process of reviewing large changes. The benefits of stacked PRs include early feedback, faster CI feedback cycles, knowledge sharing, and staying unblocked. However, there are also challenges associated with managing stacked PRs, such as updating and merging them, which can lead to merge conflicts and require manual rebasing and resolution of conflicts. To address these challenges, the Aviator CLI is introduced as a tool that provides an enhanced developer experience by automating the management of stacked PRs, including creating, updating, and merging them seamlessly.
