Project Description

CodeReview Agent is an AI-powered chatbot assistant that reviews your code in real time using GitHub Copilot Chat. It detects bugs, security vulnerabilities, and code smells — and suggests clean, refactored alternatives along with ready-to-use unit test stubs.

Designed for developers who want instant, actionable code feedback without waiting for a PR review.

How it uses GitHub Copilot

The agent connects to GitHub's Models Inference endpoint (https://models.inference.ai.azure.com) using your GITHUB_TOKEN. This is the production GitHub Copilot Chat API — the same one powering Copilot in VS Code and the CLI.
