# Dev Browser

> Use when the user asks to navigate a website, click UI, fill forms, take screenshots, scrape visible page data, test a web app, log into a browser session, or automate browser workflows with persistent page state. Inputs - target URL or existing page context, desired browser action, selectors or visible labels when known, credentials only when user explicitly provides them. Do not use when a plain HTTP request, local file edit, or Playwright test suite is the better artifact; use those tools instead. Produces dev-browser CLI commands or sandboxed JavaScript automation steps plus captured results. Escalate if login, payment, destructive actions, CAPTCHA, or sensitive personal data is involved.
