October 2025: Delivered the Agent-to-Agent Communication Demo (A2A protocol) in the a2a-samples repository, with two progressive Koog-based examples that demonstrate both basic message-based and full task-based A2A workflows. This work is anchored by commit eb3885fd019096d1abf092d476e7f5454d252c66 (#379), adding Koog Framework Examples to Samples and providing runnable Gradle tasks and clear inline documentation for immediate testing. No major bugs were reported this month. Business impact includes faster prototyping of cross-agent collaboration, improved developer onboarding, and a tangible showcase of enterprise-ready AI agent patterns. Technologies/skills demonstrated include the Koog framework, Graph-based agent architecture with GraphAIAgent, type-safe prompts, Gradle-based testing, JVM/Kotlin ecosystem, and multi-platform deployment.
