Marketplace

Pre-built toolkits for common integrations — GitHub, Linear, Slack, and more. Browse available toolkits at kernl.sh/marketplace.

When you add a toolkit, the source code is copied directly into your project — just like shadcn, so you have a familiar experience that we all love. You can read, modify, and extend the code however you like. No package dependency, just files in your toolkits/ directory that you fully control.

Adding toolkits

kernl add toolkit github

This will:

• Download the toolkit source to your toolkits/ directory
• Install any required dependencies
• Show environment variables you need to configure

Add multiple at once:

kernl add toolkit github linear

Using toolkits

After adding, import and use like any other toolkit:

import { github } from "@/toolkits/github";
import { linear } from "@/toolkits/linear";

const agent = new Agent({
  id: "assistant",
  model: anthropic("claude-sonnet-4-5"),
  toolkits: [github, linear],
});
