Show HN: Open-source pull request review agent

Hey HN! I'm Hussam, a Senior Algorithm Engineer at CodiumAI. We launched PR Agent a little over a year ago — it’s a free and open-source tool that helps with reviewing pull requests. The response has been great and more than 70 contributors have added to the project.

Today, we're launching PR Agent as a browser extension.

Key features:

- AI Chat in PRs: You can ask questions about specific code changes and the context is passed to the AI model

- Automated Code Reviews: The /review command does an automated review, focusing on potential bugs, security issues, and best practice violations

- Code Improvement Suggestions: The /improve command gives suggestions for optimizing your code

- Generate PR Descriptions: The /describe command creates PR descriptions including title, summary, step-by-step walkthrough and labels

The extension is free to use on public repositories. For private repos, we have PR-Agent Pro (14-day trial, then $19/month) with additional features like documentation suggestions, component analysis, and more.

I'd love to hear your thoughts and feedback. What features would make this most useful for your workflow? Any concerns or suggestions for improvement?
