# Browser Automation Browser automation via Vercel's agent-browser CLI. Runs headless by default; use `--headed` for visible window. Uses ref-based selection (@e1, @e2) from accessibility snapshots. ## Setup & Version Check ```bash # Check installed + print version command -v agent-browser >/dev/null 2>&1 && agent-browser --version || echo "MISSING: npm i -g agent-browser && agent-browser install" ``` Always run the version check at the start of a browser session. agent-browser iterates quickly — check for updates if the version is more than a week old: ```bash npm view agent-browser version # Latest published ``` ## Core Workflow 1. **Open** URL 2. **Snapshot** to get refs 3. **Interact** via refs 4. **Re-snapshot** after DOM changes ```bash agent-browser open https://example.com agent-browser snapshot -i # Interactive elements with refs agent-browser click @e1 agent-browser wait --load networkidle # Wait for SPA to settle agent-browser snapshot -i # Re-snapshot after change ``` ## Command Chaining Commands can be chained with `&&` in a single shell invocation. The browser persists between commands via a background daemon, so chaining is safe and more efficient than separate calls. ```bash # Chain open + wait + snapshot agent-browser open https://example.com && agent-browser wait --load networkidle && agent-browser snapshot -i # Chain multiple interactions agent-browser fill @e1 "user@example.com" && agent-browser fill @e2 "password123...
