title: Check before sharing
description: Look at each change in a real page before you send the link.
---

Ask your agent to look at the app after each change. A clean deploy proves the build passed, not that the page looks right. The next pages cover screenshots, previews, and logs.

1. Tell your agent what page to open and what you changed.
2. Ask what it sees: layout, text, and any errors.
3. Fix what looks wrong before you share the link.

Your agent renders the live page with screenshots and console checks. How it works: [Verify with look_at_app screenshots](/agents/testing/look).

:::note
If the page shows a building screen or an error instead of your app, the app has no successful deploy yet or its fleet could not start. Ask your agent for the deploy status.
