    Browser Handoff: Your Chrome, Side by Side

    Browser Handoff: Your Chrome, Side by Side

    Example session with this skill installed

    Publish my Chrome extension to the Chrome Web Store. Do all you can yourself and hand me only the steps I have to do.

    • Read your context and instructions
    • Compiled the browser handoff

    I filled the store listing myself: name, short and long description, category, privacy fields and the 3 screenshots from store/. Three steps need you, because they are sign-in, payment and the final submit.

    Opened in your Chrome, tab group

    "Publish extension", on the left half of your screen. This chat is on the right half (snapped: drag the middle edge to resize both). I closed the file tree and diff panes so the steps stay readable.

    TabWhat it is for
    Chrome Web Store Developer Dashboardsign in, register, submit
    show-group.ps1 -Match "Developer Dashboard"
group: Publish extension
expanded: yes
selected: Chrome Web Store Developer Dashboard
right half: Claude  (snapped: drag the middle edge to resize both)

    Your steps

    1. In the tab Chrome Web Store Developer Dashboard, click Sign in and use your passkey.
    2. If it asks for the developer registration, accept the developer agreement and pay the registration fee with your own card.
    3. Open the draft My Extension 1.0, check the listing I filled, then click Submit for review.

    When done, say

    "Submitted, go". I will check the page myself, open the sidebar again and tell you the review status. I will not type your password or card number, and the tab stays open until you say you are done.

    About this skill

    When your AI agent reaches a step only you can do (sign up, passkey, 2FA, payment, CAPTCHA, final publish), it hands it over cleanly: the page opens in your own Chrome, in the chat's tab group, side by side with the steps.

    What you get

    • Opens in your own Chrome, never in the agent's built-in browser. Your passkeys, saved sign-ins, password manager and 2FA work. No typing everything again in a browser that knows nothing about you.
    • Always in the chat's tab group. With several chats open you see which chat wants what, and close the whole group in one click when done.
    • 50/50 split: Chrome left, your agent right. Read the steps and do them at the same time, without switching windows. On Windows the two are snapped together: drag the middle edge and both resize.
    • Side panes hidden (Claude desktop app). File trees, diffs and terminals are closed so the steps stay readable at half screen.
    • Group expanded and brought to the front. Chrome often creates groups collapsed or behind other windows. The skill expands the group, selects the right tab and puts Chrome in front.
    • Never in an Incognito window. A normal window is brought forward first, and the skill warns if a tab still ends up in Incognito.
    • Only when you are needed. Reading pages and research stay in the agent's own tab. Your screen moves only when there is something for you to do.
    • Numbered steps, one action each. Then the agent waits and checks the page when you say done.
    • Optional guard against loose windows. A Claude Code hook blocks the common ways a chat opens a browser from the shell (start, open, xdg-open, chrome.exe, python -m webbrowser, gh --web and more). Normal commands that only mention Chrome, and headless Chrome, still run.

    The skill tells the agent never to type your passwords, card, bank or ID numbers, and never to solve CAPTCHAs for you.

    Needs

    • Windows 10/11 or macOS, with Google Chrome
    • The Claude in Chrome extension, connected to your agent
    • Claude Code (desktop app or terminal). Other agents with a Chrome tool follow the same rules, without the pane hiding.
    • Python 3 for the optional guard only

    Install

    1. Put the folder in your skills folder: ~/.claude/skills/browser-handoff/ (Windows: C:\Users\<you>\.claude\skills\browser-handoff\).
    2. Optional guard. Windows (PowerShell): py "$HOME\.claude\skills\browser-handoff\scripts\install-hook.py". Mac (Terminal): python3 ~/.claude/skills/browser-handoff/scripts/install-hook.py. It backs up ~/.claude/settings.json first. Start a new session after.
    3. To take the guard out, run the same command with --remove.

    Use

    Nothing to say. The agent uses it whenever a task needs you in the browser. You can also say "open it for me" or "I can't see the tab".

    Limits

    • Windows: the automatic split and group expand need Chrome in English. In other languages the agent asks you to put the windows side by side.
    • Mac: the first run asks to let Claude control Google Chrome and System Events (click OK). The right-half move needs Accessibility permission for Claude or your terminal. Mac windows are placed as plain halves, not snapped.
    • The split uses the main screen. Chrome in full screen (F11) is not moved.
    • Linux: the rules work, the automatic split does not.

    What's inside

    Frequently Asked Questions

    Agents often open pages in their own built-in browser or as a loose window from the shell. Neither has your passkeys or saved sign-ins, and you can't tell which chat opened it. This skill makes the agent open the page in your own Chrome, inside the chat's tab group, puts Chrome and the agent side by side and gives numbered steps.

    Windows 10/11 and macOS with Google Chrome and the Claude in Chrome extension. Built for Claude Code (desktop app or terminal). Other agents with a Chrome tool follow the same rules, without hiding the side panes. On Windows the automatic split needs Chrome in English. Linux: the rules work, the automatic split does not.

    Yes. The page opens in your normal Chrome profile, never Incognito and never the agent's built-in browser, so your passkeys, saved sign-ins and password manager are there. The agent never types your passwords, card, bank or ID numbers, and never solves CAPTCHAs for you.

    SKILL.md with the handoff rules, a README, Windows scripts (show-group.ps1, raise.ps1), a Mac script (show-tab-mac.js) and the optional shell guard (install-hook.py, block-shell-browser.py). No paid tools or API keys needed.

    No. Pages open only when you must do a step yourself; reading and research stay in the agent's own tab. Tabs land in the chat's tab group, so you close them in one click. The optional guard (a Claude Code hook) blocks the common ways a chat opens a browser from the shell. Remove it any time with --remove.
