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/tabbitappears in the skill menu orgrok inspectbefore 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
| Route | Best fit | Login and execution boundary |
|---|---|---|
| Tabbit CLI with local Grok Build | Read an existing Tabbit Browser tab with its current site session | Grok Build must run where the Tabbit CLI launcher can reach the same browser instance |
| Grok Build built-in web tools | Public pages or ordinary web research | Do not assume this shares Tabbit's cookies or your signed-in session |
| Third-party Browser Use plugin | Tasks designed for its local Chrome or Browser Use Cloud connection | Verify which browser target is selected; cloud mode is a separate browser and login |
| Cloud or headless Grok Build | Repository work that does not need a local browser | Use a separate local handoff if the task needs your desktop session |
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
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.
Install the Tabbit skill in a directory Grok Build scans, such as the project
.agents/skills/tabbit/SKILL.mdor your user skill directory. Grok's Skills guide lists.agents/skillscompatibility and shows named skills as slash commands. Use/tabbitonly after you have confirmed the skill appears.Confirm the client can run the local
tabbit-clilauncher with the permissions you intend. Permission approval is separate from skill discovery. Do not use--yoloor always-approve for a task that can reach a signed-in account.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
| Agent may prepare | Human checks in Tabbit Browser | Keep manual |
|---|---|---|
| Page title, heading, release ID, and visible status | Exact preview URL and current deployment | Edit or approve release text |
| A mismatch list with short evidence excerpts | Whether the checklist itself is current | Click Save, Submit, or Publish |
| A named review draft in the task conversation | That the draft cites the right page | Any production change or announcement |
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.
FAQ
Can Grok Build use my logged-in Grok browser session?
No. A Grok account session and a website session are separate. Sign in to the target site in the Tabbit Browser profile the local CLI reaches.
Does `/tabbit` work in Grok Build?
It works only after the Tabbit skill is installed in a Grok-discovered directory and appears in the skill list. Check `grok inspect` or the slash menu before invoking it.
Can Grok Build run Tabbit CLI from the cloud?
A cloud process cannot reach your computer’s browser unless a supported local handoff is configured. If it runs remotely, have it prepare a checklist and do the browser step locally.
Is the browser preview the same as Tabbit Browser?
No. Grok Build tools, third-party browser plugins, and Tabbit Browser can use different browser sessions. Confirm which browser target a task is using.
What should the first Grok Build browser task do?
Read one authorized release preview and return its URL, title, identifier, visible status, and evidence. Stop before editing or publishing.
Does the GEO-104 example refer to a real release?
No. `Release notes review` and `GEO-104` are a local test fixture used to illustrate the output format, not a production release.
