Automated Code Review for GitLab Merge Requests via n8n

This n8n workflow automates the process of reviewing code changes in GitLab merge requests using AI assistance. When triggered by a webhook, it fetches diff data from GitLab, processes the changes, and uses an AI model to analyze the code modifications. The workflow parses the diff, highlights the code edits, and generates a review commentary, which is then posted back to GitLab as a discussion comment. This automation streamlines code review workflows, enhances code quality assessments, and provides instant, consistent feedback for developers. It is especially useful for teams seeking to integrate automated AI-based code reviews into their CI/CD pipeline, ensuring faster review cycles and maintaining high coding standards.
