Grok Build

Add the marketplace, install with --trust, and log in.

Grok Build logo

The first /zest_login takes ~40 seconds while the plugin downloads its runtime (~24 MB). Grok buffers slash-command output, so nothing appears until it finishes. This is expected, not a hang.

Install

  1. 1

    Add the Marketplace

    In a terminal, add the official Zest marketplace for Grok Build:

    grok plugin marketplace add Winding-Labs/zest-grok
  2. 2

    Install the Plugin

    Install Zest and trust it so session hooks can run. --trust is required; without it capture stays off.

    grok plugin install zest@zest-grok --trust
  3. 3

    Reload Plugins

    If Grok was already open, type this and press r so /zest_login appears. Skip if you started a new session after install.

    /plugins
  4. 4

    Authenticate with Zest

    Inside a Grok session run the Zest login command. Do not use Grok's built-in /login — that is xAI auth.

    /zest_login
  5. 5

    Start coding

    The plugin tracks Grok Build sessions in the background. /zest_status shows auth, sync, and hook health.

Check it works

Zest has no status line in Grok Build, so the status command is the one place to look. Inside a Grok session it shows your account and workspace, what synced and what is queued, the current Grok session, the daemon, hook health, and whether this folder is tracked.

/zest_status

What it records

  • Each Grok Build session transcript: your prompts, Grok's replies, the tools it called, the model and per-turn token counts.
  • The folder each session runs in.
  • Sessions queue locally and sync in the background once you are signed in, so nothing is lost offline.

What it never sends

  • Secrets. The same redaction every Zest plugin uses runs before anything leaves your machine.
  • Folders you exclude with /zest_ignore. /zest_disable stops uploads; sessions still queue locally.

Troubleshooting

Install fails with “Couldn't scan every marketplace”

Grok also lists Claude Code's Zest marketplace, and both plugins are named zest. Install with the marketplace pinned:

grok plugin install zest@zest-grok --trust

Sessions do not appear in Zest

Run /zest_status and look at hook health. /zest_login reinstalls the hook even when you are already signed in. The hook runs when a session starts, so start a new Grok session afterwards.
