Git AI is an open source git extension that tracks AI-generated code in your repositories. Once installed, it automatically links every AI-written line to the agent, model, and transcripts that generated it — so you never lose the intent, requirements, and architecture decisions behind your code.

• AI attribution on every commit — shows a human vs AI bar with percentages on each git commit
• git-ai blame — drop-in replacement for git blame that shows the model, agent, and session behind every line
• git-ai stats — measures AI authorship across commits with JSON output (additions, deletions, accepted lines, model breakdown)
• /ask skill — lets you talk to the agent that originally wrote the code about its instructions, decisions, and intent
• IDE plugins — gutter decorations color-coded by agent session for VS Code, Cursor, Windsurf, Emacs

• No workflow changes — just prompt and commit as normal
• No detection — does not guess AI code; supported agents report exactly which lines they wrote
• Local-first — works 100% offline, no login required
• Git-native — uses an open standard for tracking via Git Notes
• Transcripts stay out of Git — Git Notes link to transcripts stored locally (SQLite), in Git AI Cloud, or self-hosted

1. Agents report written code via pre/post edit hooks
2. Each edit is stored as a checkpoint (small diff in .git/ai/)
3. On commit, checkpoints are processed into an Authorship Log attached to the commit via a Git Note
4. Attribution is preserved across rebases, merges, squashes, cherry-picks, and amends
