Codex CLI

Codex CLI is OpenAI’s open source coding agent that runs locally in your terminal. It can read, change, and run code in the working directory through natural language prompts, and it’s the terminal counterpart to the cloud-based Codex agent. Built in Rust, it supports code generation, debugging assistance, and automation tasks.

For Python programmers, Codex CLI can help write scripts, fix errors, and provide real-time suggestions without having to leave the command line.
