Anthropic is handing its Agent Skills standard, a folder-based format for teaching AI agents specific tasks, to the Agentic AI Foundation under the Linux Foundation. The goal is to keep the standard open and vendor-neutral, with a roadmap covering versioned releases and a formal proposal process.

• Over 70 agent platforms, including ChatGPT, Cursor, GitHub Copilot, and VS Code, have integrated Agent Skills since the standard was published in December 2025.
• Adoption is large: about 1 million skills published and nearly 280 million installed.
• The standard is donated along with its name, logo, GitHub organization, and agentskills.io domain, and anyone can use or contribute to it without joining the foundation.
