How BugBot Works
Under the hood, BugBot looks at the diffs in your commits and analyzes the code using the most powerful models in Cursor. When a potential issue is found, it leaves a comment with a detailed explanation and a suggestion for a fix.
- Automatic Comments: Every time a PR is updated, BugBot re-runs and leaves comments with potential issues.
- Manual Trigger: You can also run BugBot manually with
bugbot runin a comment on the PR - Fix in Cursor: Use the “Fix in Cursor” links in comments to jump straight into Cursor with full context preloaded.
Pricing
Under the hood, BugBot uses the same AI that powers Cursor and use same pricing as Max mode.
Troubleshooting
If BugBot isn’t working as expected, try these steps:
- Enable verbose mode: Comment
bugbot run verbose=trueon your PR to get detailed logging and a request ID - Check permissions: Ensure BugBot has proper access to your repository
- Verify installation: Make sure the GitHub app is installed and enabled for your repo
When reporting issues to support, always include the request ID from verbose mode output, this helps us debug much faster.
