Front matter
From the README[!IMPORTANT] This repository is deprecated. For current Codex skill and plugin examples, use the OpenAI Plugins repository (opens in a new tab). If you want to add your own skills to Codex, follow the Build plugins (opens in a new tab) 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.

$skill-installer gh-address-commentsFor experimental skills, specify the skill folder. For example:
$skill-installer install the create-plan skill from the .experimental folderOr provide the GitHub directory URL:

Colophon
How this issue was made- Source
- github.com/openai/skills, branch
main, last pushed 14 July 2026. - Licence
- All rights reserved — view on GitHub — with no detectable licence, this issue links rather than republishes: the chapters are omitted from the agent manifest and from the whole-book markdown.
- Discovery
- 44 chapters found by walking the repository tree for
SKILL.md, not by matching a directory convention. 2 distinct layouts observed:skills/.curated/*/SKILL.md,skills/.system/*/SKILL.md. - Issue colours
- Resolved from a curated brand profile — hue 170°, chroma 0.124. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.
- Heading repairs
- 1 repair applied to the front matter so the document has one
h1and no skipped levels:- Shifted “3 headings” from h1 to h2 so the chapter title is the only h1.
- Spec compliance
- Every chapter satisfies the Agent Skills specification’s frontmatter rules.
- Images
- Images inside a chapter come from the upstream repository. Where the author gave no alternative text we mark the image decorative rather than inventing a description — a plausible caption we made up is worse than none for the reader who depends on it.
- Signal
- Install counts come from skills.sh. They measure downloads, not quality, and an unranked repository is not an unread one.
- Agent surfaces
- The whole issue is available as one markdown document at
/openai/skills.md, and each chapter at its own.mdURL. - Publication
- Set by Skills Docs from the source repository. Body text is Literata at the reader’s chosen size and measure; code is Geist Mono. Nothing on this page was written by us except this paragraph.
