OpenAI Codex now officially supports skills. After a few days of people finding OpenAI was quietly adopting skills¹, the announcement came today. The thread on X goes through how skills work in Codex and shows examples on how to install third-party pre-built skills like Linear and Notion.

Two baked-in skills skill-creator and skill-installer are available in Codex, making bootstrapping and installing skills easier. See details in their official documentation.

Codex’s choice of skills location is .codex/skills, joining the war with .claude/skills, .github/skills, and .agents/skills. I really want to see a unification here.
