Awesome Codex CLI

A curated list of awesome tools, skills, subagents, plugins, and resources for OpenAI Codex CLI - the open-source AI coding agent that runs in your terminal.

Codex CLI is OpenAI's open-source terminal-based coding agent. It lets you use GPT models to write, refactor, debug, and reason about code directly from the command line - with sandboxed execution, multi-agent orchestration, MCP support, and a growing ecosystem of skills and plugins. Think of it as an AI pair programmer that lives in your terminal.

Why this list? The Codex CLI ecosystem is fragmented across dozens of repos - subagents here, skills there, plugins somewhere else. This list consolidates 271 resources into one place, organized by feature category, with opinionated descriptions so you know what's actually worth your time.
