browser-harness Direct browser control via CDP. For task-specific edits, use agent-workspace/agenthelpers.py. For , , or connection problems, read https://github.com/browser-use/browser-harness/blob/main/ .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 BHDOMAINSKILLS=1 to enable them; see the bottom section. If BHDOMAINSKILLS=1 and the task is site-specific, read every file in the matching $BHAGENTWORKSPACE/domain-skills/ / directory before inventing an approach. Invoke as browser-harness. Use heredocs for multi-line commands. Helpers are pre-imported.
