This repository showcases a production-ready enterprise agentic framework - a sophisticated system demonstrating advanced AI agent communication protocols, modern Spring Boot architecture, and professional development practices.
- Native Tools4AI Framework ReWrite: The Complete framework is recreated locally under
io.wingie.a2acore.tools4ai.*
from https://github.com/vishalmysore/Tools4AI/tree/main/src/main/java/com/t4a/*, while vishalmysores implementation was quite solid, there were some architectural decisions that i woudl have done differently and it wasnt possible to simple use OOP subclassing to get around it, so hence i opted for a rewrite to study more about the A2A and java system as a whole. - Java 17+ Compatibility: Resolved JAXB and modern Java runtime issues
The startup interface provides a comprehensive view of agent capabilities and real-time interactions:
Interactive resume showcase demonstrating technical expertise:
Real-time AI reasoning and decision-making process visualization:
