OpenAI’s Codex CLI brings terminal coding agent

Hot take: this is less “autocomplete” and more “terminal-native pair programmer,” and that makes it immediately more useful for real repo work than chat-only assistants.

• –Runs locally, so it can inspect files, edit code, and execute commands in the context of the repository.
• –Open-source Rust implementation gives it a credible performance/portability story.
• –The install path is low-friction: `npm i -g @openai/codex` or `brew install --cask codex`.
• –OpenAI’s positioning suggests this CLI is the sharp end of a larger Codex workflow stack, not just a standalone toy.
