Automated PR code reviews with GitHub, GPT-4, and Google Sheets best practices

AI-Agent Code Review for GitHub Pull Requests

Description:

This n8n workflow automates the process of reviewing code changes in GitHub pull requests using an OpenAI-powered agent.

It connects your GitHub repo, extracts modified files, analyzes diffs, and uses an AI agent to generate a code review based on your internal code best practices (fed from a Google Sheet).

It ends by posting the review as a comment on the PR and tagging it with a visual label like ✅ Reviewed by AI.

🔧 What It Does 1. Triggered on PR creation

3. Extracts code diffs from the PR

5. Formats and feeds them into an OpenAI prompt
