Worked on the PaddlePaddle/docs repository to improve documentation reliability by addressing broken references and outdated header links. Focused on enhancing DataType references and updating header file mentions from scalar_array.h to int_array.h, ensuring that documentation accurately reflected the evolving codebase structure. Utilized Markdown and technical writing skills to correct links in key files such as operator_kernel_type.md and kernel_declare_en.md, aligning them with current repository organization. Contributed two commits that validated these changes, resulting in clearer guidance for both users and developers. The work emphasized documentation hygiene and maintained consistency across technical references without introducing new features.
