Problem Statement

I’m using Claude Code on mobile and it’s fantastic for making smaller changes from my phone. However, there’s currently no way to visually verify UI changes:

1. The dev server isn’t accessible from my device (sandboxed environment)
2. Claude can take screenshots via Playwright and read them internally, but the images aren’t rendered in the mobile chat UI

Proposed Solution

• Expose the dev server URL so users can preview on their device
• Render images from the Read tool (e.g. Playwright screenshots) inline in the conversation, especially on mobile

Alternative Solutions

Use Case Example

I asked Claude on mobile to male a small change on the UI. But I had to fully merge the change into main and wait for the deployment to finish before I could validate Claude did the right thing.
