AI Post-Commit Code Review Extension

A VS Code extension that automatically reviews your committed code using AI. Just commit your changes, and the extension analyzes your diff for possible security issues, logical errors, and risky patterns using Groq LLMs.

It installs a Git post-commit hook, runs a lightweight local review server, and displays structured AI feedback directly inside VS Code.

Features

• Automatic Code Review: Triggers after every Git commit via post-commit hooks
• AI-Powered Analysis: Uses Groq's Llama3 model for intelligent code review
• Cross-Platform: Works on Windows, macOS, and Linux
• Real-time Results: Displays review results directly in VS Code
• Issue Detection: Identifies logic errors, security risks, performance issues, and code smells
• Actionable Feedback: Provides explanations, reasons, and suggested fixes
• Support for Multiple VS Code Workspaces: Automatically manages the review server for each opened workspace folder

Requirements

• VS Code 1.106.0 or higher
• Node.js (for the local review server)
• Git repository
• Groq API key (free at console.groq.com)

Installation

Install from the VS Code Marketplace or download the .vsix file from the Releases.

Setup Instructions

1. Install the extension

2. Get a Groq API key from console.groq.com

3. Ensure a Git Repository Exists:

   • Navigate to your project folder in VS Code
   • Initialize a Git repository if not already done:

     git init

4. Install the Git Hook

   • From the Command Palette:

     Post-Commit Reviewer: Setup Git Hook

     This creates a post-commit hook that triggers reviews after each commit.

5. Configure the API key:

   • Open command palette Ctrl+Shift+P on windows or Cmd+Shift+P on macOS

     Post-Commit Reviewer: Configure API Settings

   • Enter your Groq API key

6. Start the Review Server

   • The server starts automatically whenever you open a folder. You can still manage it manually:

     Post-Commit Reviewer: Start Review Server
     Post-Commit Reviewer: Stop Review Server

7. Commit Normally

   • Make Git commits as usual. The extension will automatically review your changes.
