@runbit/plugin

The plugin contract. Every provider, store, tracer, and devtool is a plugin.

npm install @runbit/plugin

import { definePlugin } from "@runbit/plugin";

const myProvider = definePlugin({
  name: "my-provider",
  setup(registrar) {
    registrar.model(someChatModel); // register a model
    registrar.tool(someTool);       // register a tool
    registrar.on((event) => { ... }); // subscribe to events
  },
});

app.use(myProvider);

Registrar is how a plugin adds models, tools, and event listeners to a runtime.

Part of Runbit — the AI Runtime. Everything executes through one small, event-driven runtime; agents, workflows, RAG, and observability are packages on top.
