The Codex CLI introduction has been revised to the following:
Key Functionality
Zero‑setup installation – a single npm install -g @openai/codex (or codex --upgrade) gets you started.
Multimodal inputs – pass text, screenshots, or diagrams and let the agent generate or edit code accordingly.
Rich approvals workflow – choose how hands‑on you want to be with three distinct modes (see Approval Modes).
Runs entirely in your terminal – perfect for quick iteration without switching contexts.
I’ll be testing out screenshots tonight.
