The average review time for Bugbot is now ~90 seconds, down from ~5 minutes. Bugbot also finds 10% more bugs per review on average — 0.62, up from 0.56 — and costs ~22% less per run.

These performance gains are made possible by progress we've made training Composer 2.5, which now powers Bugbot. Bugbot respects model block lists, and speed and performance can vary depending on your configuration.

#Run Bugbot before you push

You can now run Bugbot and Security Review with /review before pushing code. /review prompts you to choose which agents to run, or use /review-bugbot and /review-security directly.

/review also syncs with Bugbot on GitHub and GitLab. If you run /review and then open a PR with the same diff, Bugbot recognizes it, skips the review, and leaves a comment noting it has already reviewed that diff.

Available in Cursor 3.7+ and on cursor.com/agents, with support in CLI coming soon.

#Only review what's new in your PR

You can now configure Bugbot to only review what's new since the last review, keeping feedback focused on your latest updates.
