+# Cursor Bugbot Autofix
+
+## Race condition with concurrent pushes
+
+Cursor Bugbot Autofix pushes commits directly to PR branches. When a human
+or agent is also pushing to the same branch, this causes rebase conflicts
+and rejected pushes.
+
+### Recommended workflow
+
+1. **Always `git pull --rebase` before pushing** to integrate any autofix
+   commits that landed while you were working.
+2. **If a push is rejected**, fetch and check for autofix commits:
+   ```bash
+   git fetch origin <branch>
+   git log --oneline HEAD..origin/<branch>
+   ```
+3. **If an autofix commit addresses the same issue you just fixed**, skip
+   your commit (`git rebase --skip`) and keep the autofix, or resolve the
+   conflict in favor of whichever fix is more complete.
+4. **Do not force-push** to overwrite autofix commits — rebase instead.
+
+### Configuration
+
+Bugbot autofix behavior is configured at
+[cursor.com/dashboard/bugbot](https://www.cursor.com/dashboard/bugbot),
+not in this repo. To disable auto-push entirely and keep comment-only
+reviews, uncheck "Autofix" in the dashboard.
+
+### When autofix is helpful
+
+Autofix is most valuable for generated mirror PRs (`sync/public-release-mirror`)
+where no human is actively pushing. For feature branches under active
+development, consider disabling autofix to avoid the race.
