Skills for Codex

These 78 skills are compatible with Codex, making them practical alternatives and add-ons if that's the agent you already use. Because the Agent Skills format is deliberately portable — a folder with a SKILL.md file of instructions — many skills work across Codex, Claude Code, Cursor, Codex, and more, so switching tools rarely means starting your skill library from scratch. We surface each skill's declared compatibility, its license, and its current GitHub traction so you can weigh maturity against fit. Rather than recommending a single "winner", this page gives you a shortlist to compare side by side, each linking to the original repository for the authoritative install steps and documentation. The list is regenerated daily from public GitHub data, so newly published Codex-compatible skills show up here as the community releases them.
