How to install Context Engineering Kit in Grok Build
1. Add this repo as a plugin marketplace in Grok Build (once per computer):
grok plugin marketplace add NeoLabHQ/context-engineering-kit2. Install the plugin:
grok plugin install reflexion@NeoLabHQ/context-engineering-kit --trustReview 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 13 plugins; we checked git, reflexion, review. Install another the same way: grok plugin install <name>@NeoLabHQ/context-engineering-kit --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 NeoLabHQ/context-engineering-kit, then select reflexion and press i.
