A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About browser core

This is the core guide to using the browser, meant to be read before running any browser commands. It covers the snapshot-and-ref workflow, navigating pages, and interacting with elements by clicking, filling, typing, and selecting.

It also covers extracting text and data, taking screenshots, managing tabs, handling forms and authentication, waiting for content to appear, running multiple browser sessions in parallel, and troubleshooting common failures.

Use it when you want to interact with a website, fill a form, click something, extract data, take a screenshot, log into a site, test a web app, or automate any browser task.

## Questions

### Is browser core safe to install?

AIR scanned this exact version of browser core and recorded 0 findings and 2 flagged items. AIR's verdict: safe. The verdict is named by the content that was read, at commit 23907f96d92c, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/browser.

### How do I install browser core?

Open https://airmarket.ai/app/browser on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up.
