During November 2025, Guanzhi Luo contributed to the OI-wiki/OI-wiki repository by enhancing the documentation for the SelfEval tool, focusing on improving clarity and formatting within the oi.md file. Using Markdown and leveraging technical writing skills, Guanzhi clarified the tool’s usage for OI contest participants, ensuring that instructions were concise and accessible. The work addressed formatting inconsistencies to guarantee consistent rendering across platforms, which reduced the need for post-publication edits. This documentation update streamlined onboarding for new users and minimized support queries, reflecting a thoughtful approach to user experience and maintainability, though the scope was limited to a single feature.
