Show HN: R3 – A Local Code Review Tool for You and Your AI Agent (github.com)

r3 is a newly launched local code review tool designed to facilitate seamless interactions between developers and their AI coding agents. This web interface enables users to provide targeted feedback on specific lines within documents or code diffs generated by their agents. By moving away from cumbersome, linear chat interactions, r3 allows for a structured review process that enhances clarity and productivity. It automatically spins up a local web server and does not require extensive configuration, making it easy to integrate into existing development workflows. The significance of r3 lies in its ability to streamline the feedback loop, which is essential for enhancing collaboration in AI-driven development. Users can initiate both file and diff reviews, anchoring their comments to precise content rather than vague line numbers. As agents respond directly in real-time with updates on changes made, it ensures that feedback remains relevant and traceable. This tool not only improves the efficiency of AI-assisted programming but also allows developers to maintain control over the revision process without the hassle of manual tracking or disjointed communication, potentially reshaping how teams work with AI developers moving forward.
