About Codex Skills

Codex Skills are reusable instruction sets that extend your Codex agent with persistent behaviors and specialized workflows. Install a skill once and it applies automatically — shaping how the agent approaches design, debugging, testing, or any task it was built for. The catalog covers AI agents, frontend design, productivity, coding patterns, and platform integrations. Skills are installed via a single CLI command and can be combined: stack a design-taste skill with a test-driven-development skill and the agent applies both.
