Anthropic donates the Agent Skills standard to the Agentic AI Foundation

Anthropic announced on October 22 that it is donating Agent Skills to the Agentic AI Foundation (AAIF), the foundation it earlier donated MCP to. Anthropic says the standard has been integrated by more than 70 agent platforms since December 2025, including ChatGPT, Cursor, GitHub Copilot and VS Code.

• For users: Anthropic says existing skills keep working and the licenses do not change. Anyone can use the standard or contribute to it without joining the AAIF.
• Governance: a Technical Steering Committee of engineers from Anthropic, Earendil (Pi), Google, Microsoft, OpenAI and OpenCode will govern the standard.
• What moves: the Agent Skills name and logo, the GitHub organization and the agentskills.io domain. AAIF sits under the Linux Foundation; Anthropic co-founded it with Block and OpenAI. Engineers from Anthropic, Google, OpenAI and others will maintain the standard as individuals, with David Soria Parra and Mahesh Murag as Lead Maintainers.
• Adoption: Anthropic says 1 million skills have been published and nearly 280 million installed.
• Roadmap: the committee's first priority is a roadmap with versioned releases, a formal proposal process, and security guidance for skill authors and users.

Boris Cherny of Anthropic wrote that Agent Skills started as an experiment in Claude Code and was adopted across the industry, which made a neutral home a better fit. The spec is at agentskills.io, with discussion on GitHub.
