Worked on a comprehensive documentation overhaul for the C++ modernization agent in the MicrosoftDocs/cpp-docs repository, aligning the content with the General Availability release of the MSVC upgrade scenario. Focused on restructuring documentation, improving navigation, and clarifying the scope to reflect broader modernization efforts. Leveraged C++, Markdown, and Git to update FAQs, add new tutorials, and introduce configuration files that support documentation quality control and AI-guided guidance. Enhanced link validity, provided explicit code examples such as STL changes, and ensured maintainability for future updates. The work emphasized clarity and accuracy, supporting faster onboarding and a smoother release process.
