Overview and best use cases
Codex is a coding agent designed for terminal use. Its official repository documents global installation with npm and installation as a Homebrew cask, and links to product documentation and API-key setup. RefHub has not independently tested installation, compatibility, security, or workflow behavior; review the official documentation before use.
• Terminal-based coding tasks where an OpenAI coding agent fits the project workflow.
• Teams that want documented npm or Homebrew installation paths and official setup guidance.
