browser-use · Инструменти

Control a real browser via CDP: clicking, typing, navigation, logged-in sessions, JS-rendered or bot-protected pages. Not for plain HTTP fetches of public content - use curl for those.

browser-harness

Direct browser control via CDP. For task-specific edits, use agent-workspace/agent_helpers.py. For setup, install, or connection problems, read https://github.com/browser-use/browser-harness/blob/main/install.md.

When Not to Use

A basic fetch of public information needs no browser. If a plain HTTP request can read it — a public page, an API, docs — use curl or your fetch tool, and leave the browser alone. Use browser-harness when the task needs interaction (click, type, navigate), the user's logged-in session, JS rendering, or a bot-protected page. If a direct fetch fails or returns a shell page, then escalate to the browser.

Domain skills are off by default. Set BH_DOMAIN_SKILLS=1 to enable them; see the bottom section.

If BH_DOMAIN_SKILLS=1 and the task is site-specific, read every file in the matching $BH_AGENT_WORKSPACE/domain-skills/<site>/ directory before inventing an approach.

Usage

browser-harness <<'PY'
print(page_info())
PY
  • Invoke as browser-harness. Use heredocs for multi-line commands.
  • Helpers are pre-imported. run.py calls ensure_daemon() before exec.
  • First navigation for a task is new_tab(url), not goto_url(url). The daemon preserves the attached tab across separate CLI invocations, so do not call new_tab() again in every script.
  • Keep one working tab per task/site. Before opening another, inspect current_tab() and list_tabs() and use switch_tab() to reuse a matching tab. Do not leave duplicate tabs on the same URL or close tabs you did not create.
  • At task completion, close tabs created for the task that are no longer needed. Keep a tab open if the user needs to see it, it is needed for a known follow-up, or closing it could discard unsaved work or other important state.
  • new_tab() and switch_tab() attach and move the horse marker without changing Chrome's visible tab. Screenshots and normal CDP input work in the background. Never call activate_tab(target) automatically: it brings Chrome to the foreground. Call it only when the user explicitly asks to see or visibly switch to that tab. Do not pair switch_tab() with activate_tab().
  • A local daemon is a connection to the whole Chrome instance, not to one site, task, card, or agent. Omit BU_NAME and reuse the default daemon for normal sequential local work across websites, tabs, screenshots, and Codex turns. Do not invent per-job names such as gmail1375 or `slack137
