Worked on improving the correctness and maintainability of the a2aproject/a2a-samples repository by addressing a key protocol compliance issue. Focused on backend development and API integration using Java and Markdown, the main contribution involved updating the agent card file path throughout README documentation and core Java classes to match the A2A protocol specification. This adjustment ensured that all references pointed to ./well-known/agent-card.json, eliminating confusion caused by mislocated agent card files. The change enhanced onboarding for new developers, maintained consistency between code and documentation, and established a more reliable foundation for future protocol-driven enhancements within the project.
