The extension features a clean UI, with orange gutter markers highlighting AI-generated lines, and provides file badges that display the AI percentage per file. Additionally, it summarizes total AI versus human code statistics in the PR overview, ensuring that code reviews are efficient and targeted.

The extension supports both unified and split diff modes, catering to different preferences in code review. It is compatible with light and dark themes, ensuring a seamless experience across various environments. Agent Blame has a zero performance impact on page load, making it a lightweight addition to your development toolkit. To use it, a GitHub Personal Access Token is required, along with the agentblame CLI for accurate AI attribution.
