How to install Claude Night Market in Grok Build

1. Add this repo as a plugin marketplace in Grok Build (once per computer):

grok plugin marketplace add athola/claude-night-market

2. Install the plugin:

grok plugin install abstract@athola/claude-night-market --trust
✓ Install-checked in Grok Buildchecked Oct 18, 2026

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.

This repo's marketplace has 23 plugins; we checked abstract, archetypes, attune. Install another the same way: grok plugin install <name>@athola/claude-night-market --trust (names under 'What it contains'). Then start a new Grok session, or press r in /plugins, to load it.

Inside Grok Build: type /plugins, open the Marketplace tab, press a and add athola/claude-night-market, then select abstract and press i.
