Worked on the openai/codex repository to enhance user documentation, focusing on steering developers toward the latest supported model for coding tasks. Updated the FAQ using Markdown to recommend GPT-5.1 Codex, ensuring users receive clear guidance on model selection. The work emphasized documentation best practices, with all changes traceable to a specific commit for transparency and maintainability. No bug fixes or codebase changes were required, as the scope centered on improving written guidance rather than technical implementation. This approach provided low-risk, impact-oriented updates that aligned with product messaging, leveraging skills in documentation and version control to support ongoing user education.
