AI agent stdlib that works with any LLM and TypeScript AI SDK.
The goal of this project is to create a set of standard AI functions / tools which are optimized for both normal TS-usage as well as LLM-based apps and that work with all of the major AI SDKs (LangChain, LlamaIndex, Vercel AI SDK, OpenAI SDK, etc).
For example, stdlib clients like WeatherClient
can be used as normal TS classes:
import { WeatherClient } from '@agentic/stdlib'
const weather = new WeatherClient() // (requires `WEATHER_API_KEY` env var)
const result = await weather.getCurrentWeather({
q: 'San Francisco'
})
console.log(result)
Or you can use these clients as LLM-based tools where the LLM decides when and how to invoke the underlying functions for you.
This works across all of the major AI SDKs via adaptors. Here's an example using Vercel's AI SDK:
// sdk-specific imports
import { openai } from '@ai-sdk/openai'
import { generateText } from 'ai'
import { createAISDKTools } from '@agentic/stdlib/ai-sdk'
// sdk-agnostic imports
import { WeatherClient } from '@agentic/stdlib'
const weather = new WeatherClient()
const result = await generateText({
model: openai('gpt-4o'),
// this is the key line which uses the `@agentic/stdlib/ai-sdk` adaptor
tools: createAISDKTools(weather),
toolChoice: 'required',
prompt: 'What is the weather in San Francisco?'
})
console.log(result.toolResults[0])
You can use our standard library of thoroughly tested AI functions with your favorite AI SDK – without having to write any glue code!
Here's a slightly more complex example which uses multiple clients and selects a subset of their functions using the AIFunctionSet.pick
method:
// sdk-specific imports
import { ChatModel, createAIRunner } from '@dexaai/dexter'
import { createDexterFunctions } from '@agentic/stdlib/dexter'
// sdk-agnostic imports
import { PerigonClient, SerperClient } from '@agentic/stdlib'
async function main() {
// Perigon is a news API and Serper is a Google search API
const perigon = new PerigonClient()
const serper = new SerperClient()
const runner = createAIRunner({
chatModel: new ChatModel({
params: { model: 'gpt-4o', temperature: 0 }
}),
functions: createDexterFunctions(
perigon.functions.pick('search_news_stories'),
serper
),
systemMessage: `You are a helpful assistant. Be as concise as possible.`
})
const result = await runner(
'Summarize the latest news stories about the upcoming US election.'
)
console.log(result)
}
Here we've exposed 2 functions to the LLM, search_news_stories
(which comes from the PerigonClient.searchStories
method) and serper_google_search
(which implicitly comes from the SerperClient.search
method).
All of the SDK adaptors like createDexterFunctions
accept very flexible in what they accept. AIFunctionLike
objects include:
AIFunctionSet
- Sets of AI functions (likeperigon.functions.pick('search_news_stories')
orperigon.functions
orserper.functions
)AIFunctionsProvider
- Client classes which expose anAIFunctionSet
via the.functions
property (likeperigon
orserper
)AIFunction
- Individual functions (likeperigon.functions.get('search_news_stories')
orserper.functions.get('serper_google_search')
or AI functions created directly via thecreateAIFunction
utility function)
You can pass as many of these AIFunctionLike
objects as you'd like and you can manipulate them as AIFunctionSet
sets via .pick
, .omit
, .get
, .map
, etc.
npm install @agentic/stdlib
This package is ESM only and requires Node.js >= 18
or an equivalent environment (bun, deno, CF workers, etc).
Note
All heavy third-party imports are isolated as optional peer dependencies to keep the main @agentic/stdlib
package as lightweight as possible.
Depending on the AI SDK and tool you want to use, you'll also need to install the required peer dependencies.
