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.
