On 22 October 2026 Anthropic announced it is donating Agent Skills to the Agentic AI Foundation (AAIF), which sits under the Linux Foundation. Anthropic co-founded the AAIF with Block and OpenAI, and it already hosts the Model Context Protocol (MCP).
What a skill is
A skill is a folder containing a SKILL.md file, plus any scripts or reference material. It packages specialist knowledge and a repeatable workflow so an AI agent can follow it: how your team writes tests, how your app is deployed, what your brand rules are. Anthropic says the donation covers the standard itself, the name and logo, the GitHub organisation and the agentskills.io domain.
The numbers
Anthropic reports that more than 70 agent platforms, including ChatGPT, Cursor, GitHub Copilot and VS Code, have integrated the standard since it was published in December 2025. It cites about 1 million skills published and nearly 280 million installs. Maintainers from Anthropic, Google, OpenAI and others will look after it as individuals, and the roadmap includes versioned releases, a formal proposal process and security guidance for people who write and install skills.
What it means
The standard being owned by a neutral foundation, not one vendor, matters more than the headline. A team that writes its engineering rules once as skills can, in principle, use them across several AI coding tools. That lowers the cost of switching tools, which is useful in a market where models and pricing change every few weeks.
The security note is the other half. Skills carry instructions and scripts that an agent will run, so installing one is closer to installing software than downloading a document.
So what
If you commission software from a team that uses AI coding tools, ask whether their working rules are written down in a portable form, and who reviews third-party skills before they are installed. Portable, reviewed conventions are part of what separates disciplined AI-assisted development from improvised prompting. If you are planning a build and want to know how we run it, start a project.
