There’s no need for an adapter with the OpenAI SDK since all agentic tools are compatible with OpenAI by default. You can use AIFunctionSet.specs for function calling or AIFunctionSet.toolSpecs for parallel tool calling.

Usage

import { WeatherClient } from '@agentic/stdlib'
import OpenAI from 'openai'

const weather = new WeatherClient()
const openai = new OpenAI()

const messages: OpenAI.ChatCompletionMessageParam[] = [
  {
    role: 'system',
    content: 'You are a helpful assistant. Be as concise as possible.'
  },
  { role: 'user', content: 'What is the weather in San Francisco?' }
]

const res = await openai.chat.completions.create({
  messages,
  model: 'gpt-4o-mini',
  temperature: 0,
  tools: weather.functions.toolSpecs,
  tool_choice: 'required'
})
const message = res.choices[0]?.message!
console.log(JSON.stringify(message, null, 2))
assert(message.tool_calls?.[0]?.function?.name === 'get_current_weather')

const fn = weather.functions.get('get_current_weather')!

const toolParams = message.tool_calls[0].function.arguments
const toolResult = await fn(toolParams)
console.log(JSON.stringify(toolResult, null, 2))
