GitHub Review Badge is a free Chrome extension designed to streamline the process of inserting review badges into comments on GitHub pull requests. By simply typing '!r' in any comment textarea, users can access a rich dropdown menu featuring various badge types along with their descriptions, allowing for quick and efficient communication during code reviews. This tool supports nine different badge types, including 'must', 'should', 'ask', and 'good', catering to a wide range of feedback scenarios.

Additionally, the extension offers bilingual support in English and Japanese, enhancing accessibility for a broader audience. Users can enable or disable each badge individually, and any changes made to the settings are applied instantly without needing to reload the page. Furthermore, settings are synchronized across devices via a Google account, ensuring a seamless experience for developers working on multiple platforms.
