New tool called Origin enables developers to track which AI agent (Claude, Cursor, Gemini, Codex) wrote each line of code, storing attribution data directly in Git.

Origin solves the problem of unknown AI authorship by tagging every commit with the agent, prompt, model used, and cost information

Works like 'git blame' but for AI, showing [AI] or [HU] labels per line without requiring a server or internet connection

Uses Git notes to store session data on commit hashes, ensuring zero lock-in and offline functionality

CLI tool is open source under MIT license with a team dashboard available at getorigin.io

Currently integrates with Claude Code, Cursor, Gemini, and Codex to track AI-generated code contributions
