What's Agent Framework

Spring AI Alibaba Agent Framework is an agent development framework centered around the design philosophy of ReactAgent, enabling developers to build agents with core capabilities such as automatic Context Engineering and Human In The Loop interaction.

For scenarios requiring more complex process control, Agent Framework offers built-in workflows like SequentialAgent, ParallelAgent, RoutingAgent, and LoopAgent based on its Graph Runtime. Developers can also flexibly orchestrate more complex workflows using the Graph API.

Core Features

ReactAgent: Build intelligent agents with reasoning and acting capabilities, following the ReAct (Reasoning + Acting) paradigm for iterative problem-solving.
Multi-Agent Orchestration: Compose multiple agents with built-in patterns including SequentialAgent, ParallelAgent, LlmRoutingAgent, and LoopAgent for complex task execution.
Context Engineering: Built-in best practices for context engineering policies to improve agent reliability and performance, including human-in-the-loop, context compaction, context editing, model & tool call limit, tool retry, planning, dynamic tool selection.
Graph-based Workflow: Graph based workflow runtime and api for conditional routing, nested graphs, parallel execution, and state management. Export workflows to PlantUML and Mermaid formats.
A2A Support: Agent-to-Agent communication support with Nacos integration, enabling distributed agent coordination and collaboration across services.
Rich Model, Tool and MCP Support: Leveraging core concepts of Spring AI, supports multiple LLM providers (DashScope, OpenAI, etc.), tool calling, and Model Context Protocol (MCP).

Project Structure

This project consists of three core components:

Agent Framework: A ReactAgent-based development framework designed for building intelligent agents with built-in context engineering best practices. For scenarios requiring more complex flow control, the Agent Framework leverages the underlying Graph runtime to provide orchestration capabilities, supporting SequentialAgent, ParallelAgent, LoopAgent, RoutingAgent, and more. Developers can also use the Graph API to flexibly orchestrate their own workflows.
Graph: The underlying runtime for Agent Framework. We recommend developers to use Agent Framework but it's totally fine to use the Graph API directly. Graph is a low-level workflow and multi-agent orchestration framework that enables developers to implement complex application orchestration. Inspired by LangGraph, it features a rich set of prebuilt nodes and simplified Graph State definitions, making it easier to integrate with low-code platforms and implement popular multi-agent patterns.
Spring Boot Starters: Starters integrating Agent Framework with Nacos to provide A2A and dynamic config features.
