What Codex CLI does

Codex CLI helps a supervising agent decide when to hand work to Codex, and how to choose model, effort, and sandbox permissions. Use it for bounded implementation hand-offs, second-model review, or when a delegated run is needed.

Codex CLI is cataloged under AI Engineering on DirSkills. Codex CLI comes from a repository tagged agent-skills, agents-md, ai-agents, ai-coding and claude-code.

Documentation

README

Excerpt

Codex CLI

Codex is a second agent on the same machine, with its own model behind it. That is the entire reason to reach for it: a model that did not write the code has no memory of intending it to work. Everything below follows from that one asymmetry — who wrote it, who reads it, and how much thinking each step is worth paying for.

This skill is for the supervising agent, not for Codex. If you are Codex, this does not apply — calling yourself buys nothing but a second opinion from the same mind. Claude Code is the intended caller.

This is the opening of the README. Read the full README on GitHub.
