The Agent-to-Agent (A2A) Workshop is an instructor-led series designed to introduce participants to the emerging standard for agent interoperability. Grounded in the A2A project and specification, the workshop ensures learners gain a solid grasp of the protocol by working directly with Java’s standard libraries and raw APIs.

The workshop follows a branch-based structure—beginning with 01-chapter and progressing through successive lessons. Each chapter builds on the last, guiding participants as they implement communication primitives, message routing, and interoperability layers aligned with the A2A specification. Along the way, learners will explore agent identity, capability exchange, and discovery, while working through real-world scenarios where agents from different ecosystems must collaborate.

By the end of the workshop, participants will be able to:
• Understand the goals and principles of A2A as a protocol for agent interoperability.
• Implement the core A2A handshake and message-passing flows.
• Connect heterogeneous agents and frameworks.
• Gain hands-on experience with JSON-based specifications, discovery registries, and cross-agent tool invocation.

While the material can be studied independently, the greatest value comes from guided instruction and group participation, where learners debug live agent communication and analyze interoperability challenges together. This foundation equips participants to build interoperable agents and tools, accelerating adoption of standards-based, multi-agent ecosystems

Bring your favorite command-line IDE and get ready to roll up your sleeves—this workshop is fully hands-on. You’ll implement your own A2A-compliant agent from scratch and see interoperability come to life.
