npm i -g skillmds@latest skillmd add <owner>/<name> -a codex # project scope → ./.codex/skills skillmd add <owner>/<name> -a codex -g # global scope → ~/.codex/skills - Manual copy. Open any skill on SkillMD, download its SKILL.md, and save it as

Frequently asked questions
Where does OpenAI Codex look for skills?
OpenAI Codex loads Agent Skills from ./.codex/skills inside a project and from ~/.codex/skills globally. Each skill lives in its own folder as <skill-name>/SKILL.md; the agent reads the skill's description and applies it when a request matches.
How do I install a skill in OpenAI Codex?
Run npm i -g skillmds@latest once, then skillmd add <owner>/<name> -a codex in your project (add -g for global scope). The CLI writes the SKILL.md into .codex/skills for you. You can also copy the file by hand from any skill page on skillmd.com.
Do skills made for Claude Code work in OpenAI Codex?
Yes. SKILL.md is an open, agent-neutral format: the same file works across Claude Code, OpenAI Codex, Cursor, Codex, and 60+ other agents. Only the directory it lives in changes, and skillmd add -a codex handles that for you.
