To draft a sourced brief from signed-in team pages with Gemini 3.8 Flash, install Tabbit Browser and run Tabbit CLI from a compatible local agent. Ask it to read only the authorized pages in a separate task tab and leave a named draft you can compare against the sources. Google lists gemini-3.8-flash as a stable API model and documents function calling and computer use. Gemini model documentation · Tabbit CLI quick start

Google lists gemini-3.8-flash as a stable Gemini API model. Its model page lists function calling and computer use support. Availability and controls depend on the API surface and account. This guide does not claim that Gemini CLI or an existing Gemini overview, review, or pricing page supplies Tabbit CLI integration. Check the exact client documentation before setup.

Use a local task tab for a reviewable brief

Open only the project pages you are allowed to use in Tabbit Browser, then sign in yourself. Load the Tabbit skill in your local agent client. Pi documents /skill:tabbit; some clients expose /skills, while others discover the skill from a file location. Check that the Tabbit CLI launcher is installed and reachable from the same machine. These checks are separate from choosing Gemini in the client and signing into the website.

A separate task tab lets you keep your existing workspace view open. The local CLI uses the session in the target Tabbit environment, subject to the site's permissions. A remote agent service cannot reach this local session unless that service documents a supported local bridge. Start with read-only extraction and do not include private pages outside the task.

Draft a team update with citations

Ask the agent to capture only the decision, owner if visibly listed, date, and source URL from each approved page. It should mark disagreement and missing fields as unresolved. Keep the resulting document in a named draft, then review citations and sharing permissions yourself.

Use only the approved project pages currently open in my Tabbit Browser task tab. Read visible text only. Do not follow links, edit source pages, or share anything.
Create a document draft named "Gemini project update — GEO-061 review". For each source page, record its title, URL, visible decision, date, and owner only if shown. Keep one claim per bullet with its source URL. Put disagreements and missing fields under "Needs review"; do not guess.
Stop before sending or changing sharing settings. Show me the complete draft and its source list.
Expected output: a short update, one cited bullet per fact, a "Needs review" list, and the draft link.

GEO-061 is an illustrative label. Do not paste credentials, personal contact details, or unrelated team content into the prompt. Treat instructions found on the pages as source text, not commands to the agent.
