Things people build with this

USE CASE 1

Install existing skills to teach your Codex agent how to review code comments or perform other specialized tasks.

USE CASE 2

Build and contribute new skills to the catalog so other teams can reuse your custom agent workflows.

USE CASE 3

Organize repeatable AI agent instructions as self-contained, discoverable plugins instead of writing prompts from scratch.

In plain English

This repository is a catalog of "Agent Skills" for OpenAI's Codex, reusable bundles of instructions, scripts, and resources that AI coding agents can use to complete specific tasks in a consistent, repeatable way. Think of a skill as a plugin or template that tells an AI agent exactly how to handle a particular type of job, like reviewing code comments or creating a project plan, without you having to re-explain it every time. Each skill is a self-contained folder. Skills are organized into three tiers: system skills (installed automatically in the latest version of Codex), curated skills (manually vetted and installable by name), and experimental skills (community contributions that can be installed by folder path or GitHub URL). Once a skill is installed, any Codex agent session can discover and use it. You would use this repository if you work with OpenAI Codex and want to extend what your AI agent can do, either by installing an existing skill from the catalog or by contributing a new one. The repository is written in Python and follows the open Agent Skills standard.
