Installation

# Install the core package
npm install toolhub

// src/index.ts

import { ToolRegistry } from "toolhub";
import { OpenAIAdapter } from "toolhub/adapters";
import { climateDeclarations } from "toolhub/declarations/climate";
import { climateImplementations } from "toolhub/implementations/climate";

// 1. Create the registry and register climate (weather) tools
const registry = new ToolRegistry();
climateDeclarations.forEach((decl) => registry.register(decl));
registry.bindImplementations(climateImplementations);

// 2. Configure your OpenAI adapter
const adapter = new OpenAIAdapter({
  apiKey: process.env.OPENAI_API_KEY!,
  model: "gpt-4-0613",
});

// 3. Invoke the LLM, asking for weather
(async () => {
  const userMessage = { role: "user", content: "What’s the current weather in New York City?" };
  const response = await adapter.chatWithTools(
    [userMessage],
    registry.listDeclarations()
  );
  console.log("LLM Response:", response);
})();
