Safety notes— missing✓Browser Use drives a real browser and can navigate, click, type, and submit forms autonomously; run it against trusted sites and review actions before granting access to logged-in sessions or sensitive accounts.— missing✓Browser Harness can connect agents to a real logged-in Chrome profile. Remote debugging may expose active sessions, extensions, bookmarks, history, page content, downloads, uploads, and account actions to the agent. The documented Way 1 setup uses the user's everyday Chrome profile through `chrome://inspect/#remote-debugging`; require explicit user consent before attaching to sensitive accounts. The documented Way 2 setup launches Chrome with a non-default `--user-data-dir` and remote debugging port; keep that isolated profile separate from everyday browser data. Remote Browser Use Cloud sessions require `BROWSER_USE_API_KEY`, may use proxies, can persist profile state, and can continue billing until timeout or shutdown. Agents using Browser Harness can edit `agent-workspace/agent_helpers.py` and optional domain-skill files; review generated helper code and public skill contributions before reuse. Browser automation can submit forms, send messages, purchase items, scrape websites, change account settings, and upload files. Keep destructive or account-writing tasks behind confirmation.
Privacy notes— missing✓Page content, screenshots, and DOM data are sent to the configured LLM provider to plan actions, and agents can read and submit data on authenticated sites; control credentials and which pages agents can access.✓Browserbase runs browsers in its cloud, so the pages you visit, screenshots, and session data are processed on Browserbase infrastructure; avoid driving authenticated or sensitive sessions without reviewing data handling and retention.✓Browser Harness workflows can expose page screenshots, DOM text, URLs, cookies-backed login state, account data, downloads, uploads, form inputs, and extracted website data to the agent and configured model providers. Profile sync for Browser Use Cloud is documented as cookies-only, but it still moves browser authentication material into a remote browser environment. Cloud browser live URLs, proxy settings, profile identifiers, daemon logs, `/tmp` socket or pid files, and copied support artifacts may reveal browsing activity or account context. Public domain-skill PRs should not include secrets, private selectors tied to confidential apps, customer data, screenshots, credentials, tokens, or personal browsing history.
Prerequisites— none listed— none listed— none listed
  • Python 3.11 or newer, uv, git, and a durable local checkout for editable installation.
  • A Chrome or Chromium-based browser that can be attached through Chrome remote debugging, or a Browser Use Cloud API key for cloud browsers.
  • Codex, Claude Code, or another agent host that can read the Browser Harness `SKILL.md` instructions.
  • A clear boundary for which browser profile, logged-in sites, cloud browser sessions, downloads, uploads, and account actions the agent may access.
