OpenAI skills for Codex: what it does and how to install

Q: How do I install a curated Codex skill?

Run $skill-installer with the skill’s name, for example $skill-installer gh-address-comments, then restart Codex.

OpenAI’s official catalog of Agent Skills for Codex: system, curated and experimental skills.

OpenAI Codex skills in this repository come in three groups: system skills bundled with Codex, curated skills and experimental ones. Curated skills install by name with $skill-installer, experimental ones by their repository URL, and Codex needs a restart afterwards. As of checking, the README marks the repository as deprecated and points to github.com/openai/plugins for current Codex skill and plugin examples. It is still a useful reference for how Codex packages skills.
