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. This repo's marketplace has 3 plugins; we checked ts7-lsp. Install another the same way: grok plugin install <name>@CodelyTV/agent-harness --trust (names under 'What it contains'). Then start a new Grok session, or press r in /plugins, to load it.
