Agent Blame Murali מאת

Agent Blame shows you which lines of code in a GitHub Pull Request were written by AI, so you can focus your code reviews where it matters.

How It Works

• Orange gutter marks highlight AI-generated lines
• Hover over marks to see prompt details (agent, model, and prompt text)
• Unmarked lines are human-written (clean, distraction-free UI)
• File badges show AI percentage per file
• PR summary shows total AI vs human code stats

Repository Analytics

• Commit:Prompt efficiency ratio
• Filter by time period (24h, 3 days, week, month, all time)
