Developed a foundational API for chat-driven Flink Agents within the apache/flink-agents repository, focusing on extensibility and maintainability. The work centered on introducing Java annotations such as @ChatModel, @Tool, and @Prompt, along with supporting domain classes to define chat models, tools, messages, models, and events. By leveraging Java and annotation processing, the implementation enabled structured, scalable interactions with external services and reduced boilerplate for future integrations. This approach established a plugin-like architecture for agent workflows, supporting consistent and reusable patterns in software design. No major bugs were addressed during this period, with efforts concentrated on new feature development.
