Contributed to the apache/gravitino repository by delivering a documentation-driven feature focused on improving Java code generation practices. The work centered on updating AGENTS.md to clarify when to use standard Java import statements instead of inline fully qualified class names, providing concrete examples and explicit guidance for resolving class name conflicts. This approach reduces the prevalence of inline FQNs in generated code, enhancing maintainability and aligning output with established project coding standards. The changes, implemented using Java and Markdown, introduced no user-facing behavior modifications, ensuring a low-risk, review-friendly update that supports higher quality and consistency in future code generation efforts.
