# Current working spine > Mode lets Design Engineers capture a live product screen, design a change visually on an AI canvas, share the change as a live prototype, and move it toward an engineering-reviewed PR. ## Why this is the current lead This version centers the concrete product loop and the category frame: designing against live product context without making the designer touch code. 1. **Capture** a live product screen. 2. **Design** visually on an AI canvas. 3. **Share** the result as a live prototype. 4. **Move** the change toward an engineering-reviewed PR. It keeps the designer experience visual while preserving the engineering review path. ## Guardrail `PR` means a path toward engineering review. It does not mean designers bypass engineering or ship directly to production.
