Update: Codex IDE extension

OpenAI updated the Codex IDE extension docs with a direct Visual Studio Code Marketplace link and separate downloads for VS Code, Cursor, Windsurf, and VS Code Insiders. It also clarifies Windows support via WSL with a dedicated setup guide and adds tips for placing Codex in the right sidebar and handling Cursor’s horizontal activity bar. Core capabilities remain the same; this update focuses on installation and UX guidance.
