How to install skills in Codex

Install any skill for this agent
npx skills add <owner/repo> --skill <name> -a codex

Puts the skill in .agents/skills/ in your project. Replace owner/repo and name with the values on the skill's page.

Keep project-wide rules in AGENTS.md and task-specific know-how in skills, so Codex only reads a skill when the work calls for it.
