Subagent orchestration in Spring AI allows a primary AI agent to delegate tasks to specialized subagents, each operating in its own isolated context window. Using the TaskTool from the spring-ai-agent-utils library, developers can define subagents via markdown files and wire them together through a central orchestrator. The tutorial walks through setting up a Spring Boot project with OpenAI integration, creating two specialized subagents (code reviewer and documentation writer) defined in markdown, configuring the orchestrator with ClaudeSubagentReferences and TaskTool, and testing the orchestration flow. The LLM autonomously decides when to delegate to a subagent based on natural language descriptions, keeping the orchestration logic transparent and the service code minimal.
