Spins up your dev server, opens the feature in a browser, and then you just talk through what feels wrong. It auto-detects Rails, Next, Vite, Nuxt, and a handful of other stacks, or reads your launch.json if you've already configured one. The flow is dead simple: checkout a branch or PR, wait for localhost to respond, then iterate in plain conversation instead of filing tickets against yourself. No checklists, no ceremony. It's marked beta, and I suspect the 30-second server probe might be optimistic for larger Rails apps, but the core idea is sound. Best for polishing UI work where you need to see and tweak in real time.
