Summary The Gemini CLI Code Review extension addresses the need for automated code quality analysis integrated directly into a developer's command-line workflow. Targeted at users of Google's Gemini CLI, this open-source tool enhances repository quality by identifying a variety of code issues through a simple command. It aims to streamline the code review process, complementing existing CI/CD pipelines or IDE-based checks by providing immediate feedback.

How It Works This extension integrates a dedicated /code-review command into the Gemini CLI, enabling analysis of code changes present on the developer's current branch. It leverages Google's established expertise in code quality, originating from the development of the Gemini Code Assist GitHub App. The core approach focuses on providing actionable feedback directly at the command line, facilitating quicker identification and resolution of potential code smells, bugs, or style violations without context switching.
