Anthropic donates Agent Skills standard to Agentic AI Foundation

Anthropic created Agent Skills during the development of Claude Code and published it as an open standard in December 2025. The donation to the Agentic AI Foundation, which was jointly established by Anthropic, Block, and OpenAI in 2025 and already hosts the Model Context Protocol, moves the standard's name, logo, GitHub organization, and agentskills.io domain under foundation stewardship. The foundation reports that more than 70 platforms support Agent Skills, including ChatGPT, Cursor, GitHub Copilot, and VS Code, with over 1 million public skills and about 280 million installs. The proposed roadmap adds versioned releases, a formal proposal process, and security guidance, which may signal a shift toward more structured governance. For operators, the standardization makes it easier to reuse the same SKILL.md across platforms, but decisions about which skills to expose to which tasks remain with the operators themselves.
