The openai/skills repository is a catalog of reusable skills designed for OpenAI's Codex AI system. Skills are organized folders containing instructions, scripts, and resources that enable AI agents to discover and execute specific tasks in a repeatable manner. The repository serves as a distribution hub where teams and individuals can access pre-built capabilities to extend Codex's functionality without needing to rebuild the same solutions repeatedly.
The repository organizes skills into three categories based on maturity and stability. System skills located in the .system directory are automatically installed with the latest version of Codex, ensuring core functionality is always available. Curated skills in the .curated directory represent validated, production-ready capabilities that users can install by name through Codex's built-in skill-installer tool. Experimental skills in the .experimental directory offer newer or less-tested capabilities that users can opt into by specifying the skill folder or providing a GitHub directory URL. After installing any skill, users must restart Codex to activate the new capabilities.
The repository is classified across multiple AI and automation domains including language models, skill learning, AI agents, task automation, robotics, action sequences, behavior generation, reinforcement learning, program synthesis, and web navigation. This broad classification reflects the diverse range of tasks that skills can enable agents to perform. The primary language is Python, making it accessible to developers working in that ecosystem.
However, the repository includes a deprecation notice indicating that it is no longer actively maintained. The notice directs users to the OpenAI Plugins repository for current Codex skill and plugin examples. For developers wanting to add custom skills to Codex, the deprecation notice references the Build plugins guide on the OpenAI developers website, which provides instructions for creating skill-only plugins using the current recommended approach.
Each skill in the repository includes its own LICENSE.txt file within its directory, allowing individual skills to be distributed under different licensing terms. This flexibility enables contributors to share skills under licenses appropriate to their specific use cases and requirements. The repository references the Agent Skills open standard at agentskills.io, indicating alignment with broader standardization efforts in the agent skills ecosystem.
