Details

Cursor has released a major update to Bugbot. Through this update, Bugbot achieves more than 3x faster speed compared to before, costs have been reduced by 22%, and the bug detection rate per review has improved by 10%. In real-world environments, 90% of Bugbot runs complete within 3 minutes.

Key update details are as follows:

  • Pre-push review: Using the /review command, you can run the agent to identify issues before pushing code. This also syncs with PRs on GitHub and GitLab.
  • Incremental Review: Instead of re-reviewing the entire PR every time, you can configure it to focus only on the parts changed since the last review, improving feedback efficiency.
  • Composer 2.5 applied: This performance improvement was achieved through Composer 2.5 model training and harness improvements.

This feature is available in Cursor 3.7+ and at cursor.com/agents, with CLI support coming soon.
