Developed security and onboarding-focused documentation for Copilot Spaces within the github/github-mcp-server repository, delivering detailed Personal Access Token (PAT) Access Guidance. The work defined fine-grained PAT requirements and explicit access limitations, aiming to improve security posture and reduce misconfiguration risks for Copilot usage. Using Markdown and technical writing skills, the documentation standardized PAT policies and clarified governance, enabling safer and faster developer onboarding. The contribution was executed through a co-authored commit, reflecting strong cross-team collaboration. No bug fixes were addressed during this period, as efforts concentrated on documentation quality, policy alignment, and supporting more efficient developer workflows for token access.
