Cursor's Composer 2.5 powers Bugbot, dropping review time from ~5 minutes to ~90 seconds.
Story
Bugbot now finds ~10% more bugs per review (0.62 vs 0.56) at ~22% lower cost per run. A new /review flow runs Bugbot and Security Review before push, dedups against the eventual PR, and supports incremental "only what's new" review. Cursor also added always-on Automations with GitHub and Slack triggers. (Cursor) This is the chat-IDE becoming a standing review-and-automation agent in your loop, which is the Shopify thesis showing up as a product feature. Pre-push review that dedups against the PR is the kind of friction removal that actually changes behavior.
