LangChain4j Tool & Function Calling
Implements robust tool and function calling patterns for AI agents using the LangChain4j framework in Java.
This skill provides comprehensive implementation patterns for LangChain4j’s tool system, enabling AI agents to interact seamlessly with external APIs, databases, and services. It covers everything from basic annotation-based tool definitions using @Tool to advanced features like dynamic tool provisioning, concurrent execution, and resilient error handling. By standardizing how agents invoke external functions, this skill helps developers build complex, agentic Java applications that move beyond text generation to perform real-world actions with production-grade reliability and observability.
