Anthropic donates Agent Skills to the Agentic AI Foundation
Anthropic has transferred the Agent Skills standard, including the name, logo, GitHub organization and agentskills.io domain, to the Agentic AI Foundation under the Linux Foundation, and says 70 or more agent platforms have integrated it with more than a million skills published and 280 million installs so far.
Why it mattersA team that was holding off on building against Agent Skills because the format was one company's can treat it as a published standard with Google, OpenAI and Anthropic maintainers writing versioned releases and a public proposal process.
A team that writes agents for Claude Code, Codex, Gemini and the other platforms that read Agent Skills now has a published standard behind the format rather than one vendor's documentation. Anthropic announced on 22 October that it is giving the Agent Skills standard to the Agentic AI Foundation, the same Linux Foundation body that holds the Model Context Protocol specification.
The transfer covers the name and logo, the GitHub organization and the agentskills.io domain, so a future version of the specification will carry the foundation's marks and live at its address.
What Anthropic says it is giving up and keeping
Anthropic says it is committed to keeping Agent Skills "open, community-driven, and vendor-neutral," and names three things the foundation will add on top of what has been published so far: versioned releases, a formal proposal process, and security guidance. Governance will mirror the Model Context Protocol's, which the Agentic AI Foundation already runs under the Linux Foundation.
The lead maintainers named are David Soria Parra and Mahesh Murag. Anthropic says engineers from itself, Google, OpenAI and other companies will maintain the standard as individuals. The Agentic AI Foundation was co-founded by Anthropic, Block and OpenAI in 2025.
The numbers Anthropic cites
The announcement puts three figures against the format's take-up to date. Seventy or more agent platforms have integrated Agent Skills. More than one million skills have been published. The format has been installed more than 280 million times. All three are Anthropic's own counts and the item carries them as such.
For a team deciding whether to build against it
Agent Skills is the second specification Anthropic has released as open and then handed to the Agentic AI Foundation, after the Model Context Protocol. For a team that was waiting to see whether the format would stay single-vendor before building against it, the move removes one of the two most common reasons a project is held back on an open specification. The other reason, which the announcement does not address, is whether other agent platforms will treat the versioned releases from the foundation as the primary reference rather than Anthropic's own documentation. The seventy-platform figure is the number to watch there: a platform that reads the foundation's version rather than Claude's implementation is how the format becomes a standard in practice, and a platform that keeps releasing its own extensions is how it does not.
The announcement does not give a date for the first foundation-released version, does not say when agentskills.io will move hosts, and does not list which of the seventy integrating platforms have agreed to adopt the foundation's governance. A team planning around Agent Skills should treat today as the start of the transfer, with later versions still to come.
