Anthropic donates the Agent Skills open standard to the Agentic AI Foundation and says 70+ platforms have integrated it, after donating MCP to the AAIF in 2025 (Anthropic)
Today, we're donating Agent Skills, the open standard that gives AI agents specialized knowledge and workflows, to the Agentic AI Foundation (AAIF).
Anthropic has transferred ownership of the Agent Skills open standard to the Agentic AI Foundation (AAIF), a non-profit organization co-founded by Anthropic, Google, and OpenAI. Over 70 different agent platforms have already integrated Agent Skills since its December 2025 launch. A skill is a folder containing a SKILL.md file with a task or domain-specific instruction, along with any necessary scripts or reference material.
Anthropic developed the skills while working on its own AI coding assistant, Claude Code. Upon publishing Agent Skills as an open standard, developers quickly began contributing thousands of skills on GitHub and writing loaders for various platforms. Currently, there are over 1 million published skills and nearly 280 million installations.
Anthropic donated both Agent Skills and the Model Context Protocol (MCP) to the AAIF under the Linux Foundation umbrella, ensuring the standard remains community-driven and vendor-neutral. The AAIF will provide a neutral platform for managing the standard's future development, with Anthropic, Google, and OpenAI engineers serving as Lead Maintainers.
The project will focus on versioned releases, a formal proposal process, and security guidelines for skill development.
