Codex Skills is a free directory of 872 MIT-licensed Agent Skills for OpenAI Codex. Each skill is a complete SKILL.md playbook that Codex loads the moment a task needs it: PDFs, React, Postgres, security reviews, AGENTS.md and more across 28 categories. Install any skill with one command, grab curated collections like the Starter Pack, and read every line before it runs. No account, no telemetry. Works in the Codex CLI, IDE and app.
