Repository context

openai/codex

Apache-2.0 OpenAI coding-agent platform centered on the standalone Codex CLI, with desktop and IDE entry points, Python and TypeScript SDKs, structured and streaming turns, persistent sessions, model-visible tools, and OS-specific sandbox enforcement; it is an alternative or companion to Claude Code rather than a Claude Code extension.
