Anthropic hands the Agent Skills standard to the Linux Foundation's AAIF
Sorted AI23 OctAnthropic is donating Agent Skills, the open standard that packages an agent's know-how as a folder with a SKILL.md file plus any scripts or reference material, to the Agentic AI Foundation under the Linux Foundation, which also holds MCP. Anthropic says more than 70 agent platforms, including ChatGPT, Cursor, GitHub Copilot and VS Code, have integrated the standard since December 2025, and that 1 million skills have been published and nearly 280 million installed. The name, logo, GitHub organisation and agentskills.io domain move to the foundation, engineers from Anthropic, Google, OpenAI and other companies will maintain it as individuals, and you can keep using or contributing to it without joining. The proposed roadmap covers versioned releases, a formal proposal process and security guidance for people who write and install skills.
Why it matters: Skills written in the SKILL.md format now sit under a neutral standard rather than one vendor, so they are less tied to a single tool; watch for the planned security guidance before installing skills written by others.
