How to use skills
[!IMPORTANT] This repository is deprecated. For current Codex skill and plugin examples, use the OpenAI Plugins repository. If you want to add your own skills to Codex, follow the Build plugins guide, which includes instructions for creating a skill-only plugin.
Agent Skills
Agent Skills are folders of instructions, scripts, and resources that AI agents can discover and use to perform at specific tasks. Write once, use everywhere.
Codex uses skills to help package capabilities that teams and individuals can use to complete specific tasks in a repeatable way. This repository catalogs skills for use and distribution with Codex.

Installing a skill
Skills in .system are automatically installed in the latest version of Codex.
To install curated or experimental skills, you can use the $skill-installer inside Codex.
Curated skills can be installed by name (defaults to skills/.curated):
$skill-installer gh-address-comments
For experimental skills, specify the skill folder. For example:
$skill-installer install the create-plan skill from the .experimental folder
Or provide the GitHub directory URL:
$skill-installer install https://github.com/openai/skills/tree/main/skills/.experimental/create-plan
After installing a skill, restart Codex to pick up new skills.
License
The license of an individual skill can be found directly inside the skill's directory inside the LICENSE.txt file.
