How to install WalkerOS in Grok Build

grok plugin install elbwalker/walkerOS --trust
✓ Install-checked in Grok Buildchecked Oct 18, 2026

Needs your own API key or sign-in to work fully. We check that it installs and loads, not your account.

Review before you trust it. --trust lets this plugin's hooks, MCP servers and scripts run code on your computer. It's a community repo that neither xAI nor GrokStacks has reviewed, so read its code first.

We install this repo directly: Grok Build 1.0.62 can't install it through its own marketplace file. Then start a new Grok session, or press r in /plugins, to load it.

Command format: Grok Build's plugin guide

Needs a sign-in. Its MCP server is hosted by the vendor, and most hosted MCP servers ask you to sign in the first time. In Grok, open /mcps, select the server and press i to sign in.

What we checked: on Oct 18, 2026 it installed with grok 1.0.62 and Grok found 22 skills. That's an install check only: we haven't run it in a live Grok session.

  • walkeros-understanding-flow — Use when learning walkerOS architecture, understanding data flow, or designing composable event pipelines. Covers Source→Collector→Destination pattern and separation of concerns.
  • walkeros-understanding-destinations — Use when working with walkerOS destinations, understanding the destination interface, or learning about env pattern and configuration. Covers interface, lifecycle, env mocking, and paths.
  • walkeros-understanding-sources — Use when working with walkerOS sources, understanding event capture, or learning about the push interface. Covers browser, dataLayer, and server source patterns.
  • walkeros-understanding-transformers — Use when working with walkerOS transformers, understanding event validation/enrichment/redaction, or learning about transformer chaining. Covers interface, return values, and pipeline integration.
  • walkeros-understanding-stores — Use when working with walkerOS stores, understanding key-value storage in flows, or learning about store injection via env. Covers interface, lifecycle, $store. wiring, and available store packages.
  • walkeros-understanding-development — Use when contributing to walkerOS, before writing code, or when unsure about project conventions. Covers build/test/lint workflow, XP principles, folder structure, and package usage.

  • walkeros-create-source — Use when creating a new walkerOS source to capture events (browser source, dataLayer interception, server/HTTP source, webhook receiver, event capture), web or server-side. Example-driven workflow: research the input format and define step
  • walkeros-create-transformer — Use when creating a new walkerOS transformer to modify events in the pipeline (validate, enrich, or redact) at a before/next chain position. Example-driven workflow for the transformer interface, return values, and chaining.
  • walkeros-mapping-configuration — Use when configuring walkerOS event mappings for specific use cases. Provides recipes for GA4, Meta, custom APIs, and common transformation patterns.
  • walkeros-testing-strategy — Use when writing tests, reviewing test code, or discussing testing approach for walkerOS packages. Covers env pattern, dev examples, and package-specific strategies.
