How to use Grok Build with a signed-in browser

Grok Build can work with a signed-in website when the Grok Build process runs on the same computer as Tabbit CLI and Tabbit Browser. Install the Tabbit skill where Grok Build discovers skills, confirm it can call the local CLI, sign in to the target site yourself in Tabbit, then ask for a read-only check of a release preview. Grok Build is the local coding agent; it is separate from the Grok model and from Grok on the web. This guide uses a release-notes preview so you can compare the agent's summary with the page before approving copy.

Grok Build's own docs describe a terminal agent with shell, file, and web tools, and say shell and file actions ask permission by default. That does not automatically connect it to your browser. Tabbit CLI supplies the browser route. A Reddit user working with Grok Build described the friction of tracking image files in a large project and suggested showing them in the browser preview. That is a useful reminder to make review artifacts visible, but it is one user's workflow, not a verified Grok feature. Original discussion.

Key takeaways

• Use Grok Build as the host process, Tabbit CLI as the local browser connector, and Tabbit Browser as the environment holding the website login.

• Install the Tabbit skill under a Grok-discovered skill root such as .agents/skills/tabbit/; confirm /tabbit appears in the skill menu or grok inspect before using it.

• Sign in manually. A logged-in Grok account, a Grok Build session, and a website session are three different things.

• Start with a read-only preview check. Keep the release draft in the agent conversation and stop before editing or publishing the website.

Decide which browser route you need

The Grok Build getting-started guide documents grok, persistent login to grok.com, tool permissions, and headless mode. Those are host features. The Grok 4.7 model guide covers a different question about the model; a model selection does not decide which browser a local client can reach.

Connect the local client

1. Open Tabbit Browser and sign in to the release-preview site yourself. Open the specific preview page and confirm its release title and status are visible.

2. Install the Tabbit skill in a directory Grok Build scans, such as the project .agents/skills/tabbit/SKILL.md or your user skill directory. Grok's Skills guide lists .agents/skills compatibility and shows named skills as slash commands. Use /tabbit only after you have confirmed the skill appears.

3. Confirm the client can run the local tabbit-cli launcher with the permissions you intend. Permission approval is separate from skill discovery. Do not use --yolo or always-approve for a task that can reach a signed-in account.

4. Ask it to inspect one page in a task tab. Check the title, URL, release identifier, and visible status against the original Tabbit tab.

For the connection details, see the Tabbit CLI guide and how to connect an agent to an existing browser. A separate task tab lets you leave your research and review tabs open. The session reuse guide explains why site login still depends on the selected browser profile.

Review a release note without publishing it

Use this fixture prompt for a test page or a release preview you are authorized to inspect. The expected draft has a name, the page evidence, a mismatch list, and a human review checkpoint.

Use the Tabbit skill and Tabbit CLI from this local Grok Build session.
The release preview is already open in my Tabbit Browser and I am signed in.
Do not edit, save, submit, or publish anything on the site.

Create a draft named "Release preview check, draft 01" with:
- page title and exact URL
- release identifier and status shown on the page
- the heading and first paragraph of the release note
- any difference between the release note and this checklist: [paste a non-sensitive checklist]
- a short evidence quote for each difference
- a final section called "Human review before publish"

If you cannot see the signed-in page, stop and say which connection check failed.

For the local fixture used in this topic batch, the visible heading was Release notes review and the record was GEO-104. Treat these as test data, not a real release. Keep the screenshot or preview URL beside the draft. The first-task checklist walks through evidence checks; the MCP vs CLI comparison helps choose the connector; and the Codex setup example shows another local-client setup.

Set a safe stopping point

If Grok Build runs in a remote container, a skill can be visible while the local CLI is unreachable. If the CLI is reachable but opens a login page, the browser profile or site session is wrong. Diagnose those layers separately. For browser input risks, read agentic browser security guidance and browser tools for agents. To install the browser, use the Tabbit Browser installation guide.

A practical first step is to run the prompt against a harmless release fixture and compare its page title, URL, and record with the visible browser. Keep the draft for review; do not let a successful read become permission to publish.
