PR-AI-Agent: Intelligent Pull Request Analysis System

System Architecture

Overview

PR-AI-Agent is a sophisticated automated code review system that leverages AI to analyze GitHub Pull Requests. Built with a focus on scalability and reliability, it provides detailed insights into code quality, security vulnerabilities, performance implications, and documentation completeness.

Key Features

• Asynchronous Processing: Handle multiple PR reviews simultaneously
• Scalable Architecture: Each component can be scaled independently
• Real-time Status Updates: Track review progress through API endpoints
• Detailed Analysis: Comprehensive code review covering multiple aspects
• Persistent Storage: Reliable task and result management
• Error Handling: Robust retry mechanisms and error recovery
