The use of AI in open-source (OSS) project maintenance is becoming increasingly popular, particularly for tasks such as code reviews and security checks. An AI can quickly scan through pull requests for errors and security flaws, providing some breathing room to project maintainers. This allows them to focus on more strategic tasks like feature development and community engagement. Popular OSS projects are turning to AI for help with high-level PR summaries, expert code walkthroughs, interactive code reviews, and consistency in their coding standards. By using an AI code reviewer, maintainers can identify errors, enforce coding standards, spot security risks, explain code changes, tell maintainers where to focus, and ultimately make a huge difference in the efficiency of OSS project maintenance.
