-A powerful and flexible library for building AI agents using the Vercel AI SDK. This project provides a simple yet powerful way to create and manage AI agents with customizable flows, tools, and contexts.
+AI SDK Agents is an extension of the standard [Vercel AI SDK](https://sdk.vercel.ai/docs) API. It enables you to build advanced generative applications using patterns and agent compositions that are not supported by the Vercel AI SDK out of the box. With this library, you can define your own agents, compose them together, and call agents as tools within other agents, unlocking complex reasoning and orchestration flows.
