Anthropic donates Agent Skills to the Agentic AI Foundation

Anthropic announced on 22 October 2026 that it is donating Agent Skills, the open standard for giving AI agents specialised knowledge and workflows, to the Agentic AI Foundation (AAIF), which sits under the Linux Foundation. Anthropic says it co-founded the AAIF with Block and OpenAI last year and previously donated the Model Context Protocol (MCP) to it.

What a skill is

Per Anthropic, a skill is a folder containing a SKILL.md file that teaches an agent a specific task or domain, along with any scripts or reference material it needs. Anthropic says it developed skills while working on Claude Code, which handled general knowledge work well but often lacked the procedural knowledge that real business tasks need.

For a team rolling out agents, the practical point is portability: a procedure written as a skill is a plain folder, not a configuration locked to one product.

Adoption figures, as Anthropic reports them

• More than 70 agent platforms, including ChatGPT, Cursor, GitHub Copilot and VS Code, have integrated Agent Skills since Anthropic published the standard in December 2025.
• Anthropic launched skills in October 2025; within weeks, it says, developers published thousands of skills on GitHub and wrote loaders for Codex, Cursor and OpenCode.
• So far 1 million skills have been published and nearly 280 million installed, according to the announcement. The post does not say how these were counted or how many are in active use.

What changes with the donation

Anthropic is donating the Agent Skills name and logo, the GitHub organisation and the agentskills.io domain. It says people can keep using or contributing to the standard without joining the AAIF. Engineers from Anthropic, Google, OpenAI and other companies will maintain it as individuals, with David Soria Parra and Mahesh Murag as Lead Maintainers.

Anthropic has proposed a starting roadmap covering versioned releases, a formal proposal process, and security guidance for people who write and install skills. As with MCP, it says the project will prioritise community input and transparent decision-making. These are proposals, not shipped changes.

What to do with this

• If you are writing internal agent procedures, keeping them as SKILL.md folders in version control is the portable choice the announcement describes; check each tool you use actually loads them before you rely on that.
• Treat third-party skills like third-party code. A skill can include scripts, and the security guidance is still a proposal, so review what a skill runs before installing it on a work machine.
• Watch for the first versioned release. Until there is one, the specification can change under you.

What the announcement leaves out

This is Anthropic describing its own project. It names no independent count of adoption, no governance terms for the AAIF beyond the maintainer line-up, and no timeline for the roadmap items. Whether competing platforms treat skills as a first-class feature or a compatibility layer is not addressed.
