Agent Browser

A clean wrapper around Vercel's agent-browser CLI that makes browser automation actually bearable for testing and scraping. The ref-based targeting system (@e1, @e2, etc.) is genuinely clever: take a snapshot, get labeled elements, interact with them by reference instead of fighting with fragile CSS selectors. Works well for E2E tests, form filling, and grabbing screenshots. The workflow is straightforward: open a page, snapshot to see what's there, click or fill using refs, snapshot again to verify. Includes Python wrappers if you want to script it. Just remember refs expire when the page changes, so you'll be snapshotting often. Better than wrestling with Selenium for quick automation tasks.
