    "content": "---\nname: signed-in-chrome-browser\ndescription: Connect, verify, or troubleshoot an owner-authorized signed-in Chrome browser for an AI agent, including OpenMausBot native Chrome and desktop discovery. Use for browser connection setup and routing failures; ordinary browsing does not require this skill.\n---\n\n# Use signed-in Chrome with an AI agent\n\nUse the browser and account the owner requested. A saved profile name, enabled toggle, mounted tool catalog, or successful connection request is not proof that the intended page is accessible. Verify the resulting state before reporting success.\n\nThis skill is instructions, not a browser driver, extension, permission grant, or security-challenge bypass. It requires a working browser-control runtime and the owner's authorization. Never invent tool APIs that the runtime does not expose.\n\n## Discover the actual connection\n\n1. Inventory the available browser and computer services, then read their current documentation. Distinguish a built-in automation browser, an extension connected to a user browser, and a native desktop/Chrome connection. Their sessions and account cookies may differ.\n2. Confirm which machine hosts the browser. Opening a Mac-hosted app through a tunnel on Windows does not move its browser to Windows. A Windows installation is unnecessary merely to view that hosted app; controlling a Windows-local browser requires its own supported connection.\n3. Check the selected assistant, conversation destination, available engine capabilities, current grant expiry, and allowed website origins. Keep action approvals separate from browser connection permissions. Use the narrow website scope needed for the requested work.\n4. Prefer the current authorized connection. Do not silently substitute a different account or browser, restart the owner's browser, copy cookies/profile data, or expose a debugging port to create access.\n\n## OpenMausBot native Chrome route\n\nApply this section only when the installed app actually provides these services. Read the mounted tool schemas for exact arguments.\n\n- In the Mac desktop app, Web can create a time-limited, website-scoped Chrome grant and opt an assistant into signed-in Chrome with This computer selected. An explicit conversation destination can override the assistant's default; check both. Auto mode may require acknowledgment before enabling local-computer tools.\n- In the observed OpenMausBot 0.2.11 build, new Chrome grants require the host desktop app. The tunnel-only Web panel does not provide equivalent controls. Do not promise a remote on/off feature that has not been implemented. Recheck newer releases rather than treating this limitation as permanent.\n- Use the ordinary `computer` service for `list_apps` and `list_windows`, under its separate authorization. The scoped `omb_chrome` service is browser-only. A desktop-discovery refusal from that service is not a reason to expand its manifest.\n- Freshly observe the intended Chrome process and exact native window. Confirm the visible profile/account label; do not reuse saved process IDs or window IDs as if current.\n- With `omb_chrome`, call `browser_prepare` using `strategy.kind=existing_profile` and the observed process/window, then `get_browser_state` to bind and verify. Preserve the same session, native window, returned target, and tab throughout the operation. Use only fresh returned references for subsequent browser actions.\n- After navigation or a stale binding, inspect the resulting state. If instructed by the runtime, prepare and bind the same window again. Do not ask for another owner grant merely because a target or tab reference expired.\n\n## Handle demonstrated failures precisely\n\n**Internal Chrome New Tab:** The native SDK version observed with OpenMausBot 0.2.11 could bind New Tab yet refuse scoped navigation because the current `chrome://new-tab-page/` URL was not HTTP(S). When the ordinary computer service is independently authorized, navigate the exact observed window through Chrome's normal address bar to the approved website, verify it loaded, then prepare/bind through the browser service. This is a supported native UI startup path, not a fix to the SDK limitation or permission to visit additional sites.\n\n**Ambiguous background keyboard input:** Multiple windows in one Chrome process can make a process-scoped key unsafe. Inspect the refusal and use a supported exact-element action or authorized foreground action. Read back the page; a key-delivery receipt marked unverifiable is not proof of navigation. Do not repeat uncertain input blindly.\n\n**Large setup proof:** Preserve a refusal caused by a truncated accessibility proof. A clean window in the same authorized profile may let unchanged setup checks complete. Do not disable the check, clone the profile, or infer success from a partial tree.\n\n**Desktop calls reaching a browser-only manifest:** Check tool namespace and transport routing. In a Codex host that mounts multiple stdio MCP servers, merging their environment variables can overwrite shared names such as `OMB_CUA_ARGS`. OpenMausBot 0.2.11 isolates each server's private launch environment. Repair this in the host transport; prompt changes cannot repair a socket collision. Keep credentials out of argv/logs and verify isolation with synthetic fixtures, not production credentials.\n\n**Cloudflare or other site challenges:** Stop automated retries and report the specific challenge. A real signed-in Chrome connection does not guarantee site acceptance. Separate browser profiles isolate cookies, not necessarily public IP traffic. Do not claim that automation caused unrelated personal-browser challenges without evidence. Do not rotate identities, spoof fingerprints, or disable browser protections to get past a challenge.\n\n## Verify a small read before acting\n\nRead one owner-requested page and confirm the visible account, relevant page identity, and expected data. Report separately: connection mounted, native window observed, exact browser binding established, site read succeeded, and any remaining site restriction. State the engine and platform actually exercised; a transport fixture does not prove another model or operating system works.\n\nFor a later write, use the owner's authorized scope and applicable review requirements. After a send or submission, verify its receipt and resulting state. Preserve successful receipts; do not replay an uncertain write after reconnecting, switching models, or renewing a grant. Leave new contractual prompts for owner review when acknowledgment is required.\n\n## Evidence and limits\n\nThe native workflow above was exercised on macOS with Codex and OpenMausBot 0.2.11: independent desktop discovery, existing-profile preparation, exact binding, approved-site navigation and a signed-in page read succeeded. Windows packaging and synthetic checks passed; a signed-in account on Windows was not validated. Other engines require their own live acceptance check. The tunnel grant UI and native SDK startup/trusted-input limitations were not fixed by this skill.\n\nReference: [Cloudflare challenge troubleshooting](https://developers.cloudflare.com/cloudflare-challenges/troubleshooting/).
