During August 2025, Xiaofei Cao contributed to the MicrosoftDocs/azure-dev-docs repository by enhancing documentation related to Azure Resource Manager. Xiaofei focused on improving the reliability and clarity of technical content by adding a detailed note about minimum version requirements for azure-core-http-netty and BOM, addressing compatibility with large HTTP headers in long-running operations. The work involved careful use of Markdown for documentation hygiene and site-relative linking to strengthen navigation and link integrity. While the scope was limited to a single feature and did not include bug fixes, the updates demonstrated attention to cross-repo consistency and versioning constraints within the documentation ecosystem.
