Show HN: A CLI tool for agentic code review and auto-fixing (github.com)

A new command-line interface (CLI) tool called Ralph Review has been launched, designed to automate the code review and fixing process using two distinct AI agents: a reviewer and a fixer. This tool is significant for the AI/ML community as it streamlines the often tedious process of code validation by systematically looping through review-fix cycles until the code is deemed clean—reducing developer workload and improving code quality through independent verification and recommendations. Ralph Review begins by optionally simplifying code before a reviewer agent analyzes the changes, creating a structured output that a fixer agent then verifies and corrects as needed. This setup prevents bias, as the fixer independently assesses the reviewer’s findings, applying minimal necessary changes and generating a summary of actions taken. The iterative process continues until no actionable issues remain or a predetermined iteration limit is reached, allowing developers to experiment with different coding agents like Claude, Codex, or Gemini in each role. The tool's ability to enhance the reliability of code quality checks while minimizing manual overhead represents a notable advancement in the application of AI in software development.
