Cursor adds local Bugbot runs and selective PR change reviews
TL;DR
Bugbot now runs on Composer 2.5 for 3x faster performance at 22% lower cost. Users run Bugbot and security reviews locally via /review and limit to new changes since the last review.
What changed
Developers can now run Bugbot locally in Cursor with the /review command on Composer 2.5 to handle Security Reviews before pushing. Vibe Builders and Basic Users gain options to configure reviews that focus only on new PR changes since the last pass. The update runs three times faster at twenty two percent lower cost.
Why it matters
Developers see quicker iteration on code reviews with the speed and cost gains from Composer 2.5 compared to prior setups. Basic Users complete focused PR checks in less time during daily workflows while Vibe Builders maintain momentum across multiple iterations.
What to watch for
Track performance against alternatives like standard GitHub PR reviews on sample repositories. Verify by executing the /review command locally on a test branch and confirming it surfaces only the delta changes.
Who this matters for
- Vibe Builders: Use the /review command to check only new changes and keep your project momentum high.
- Developers: Run Bugbot locally with Composer 2.5 to catch security issues before you push to your repository.
Harsh’s take
Cursor is tightening the loop between writing code and shipping it. Moving Bugbot and Security Review locally via the /review command removes the friction of waiting for CI/CD pipelines to trigger remote checks. The 3x speed increase in Composer 2.5 makes local linting and security scanning feel like a real-time assistant rather than a heavy batch process.
The ability to review only the delta since the last pass is the real win for productivity. It prevents the cognitive fatigue of re-scanning old code and keeps the focus on the immediate task. This update signals a shift where the IDE is no longer just a text editor but a local quality assurance hub.
Operators should adopt this local-first workflow to reduce cloud compute costs and shorten their feedback cycles.
