Agent Skills Donated to the Agentic AI Foundation

On 22 October 2026 Anthropic handed the SKILL.md standard — name, logo, GitHub organisation and the agentskills.io domain — to the AAIF under the Linux Foundation, so no single vendor decides where it goes next

Official Source

Summarised from Anthropic's announcement of 22 October 2026.

Features

  • ✓ What moved is the standard itself: the Agent Skills name and logo, the GitHub organisation holding the spec and reference implementation, and the agentskills.io domain
  • ✓ The AAIF sits under the Linux Foundation and was co-founded by Anthropic with Block and OpenAI; it already holds MCP
  • ✓ Anthropic reports 1 million skills published and nearly 280 million installs, with 70+ agent platforms integrated including ChatGPT, Cursor, GitHub Copilot and VS Code
  • ✓ Governance shifts from one vendor to a neutral body: engineers from Anthropic, Google, OpenAI and others maintain it as individuals, with David Soria Parra and Mahesh Murag as Lead Maintainers
  • ✓ The proposed roadmap covers versioned releases, a formal proposal process, and security guidance for the people who write and install skills

How to Use

  1. Confirm you do not need to change anything: the format is unchanged, existing SKILL.md files keep working, and contributing or using it needs no AAIF membership
  2. Use the moment to audit your skill library: who owns each one, what it instructs, and which scripts or external commands it can run
  3. Treat installing a third-party skill like installing software: check the source, the permissions it wants and what its scripts actually do before it touches a production agent
  4. Watch agentskills.io and the AAIF proposal process — future spec changes go through public proposals, not one vendor's changelog

FAQ

What exactly was donated?

Per Anthropic's announcement (https://www.anthropic.com/news/donating-agent-skills-to-the-agentic-ai-foundation), the donation covers the Agent Skills standard itself: the name and logo, the GitHub organisation that holds the specification, and the agentskills.io domain. The file format is unchanged, so skills you already wrote keep working.

What does a skill actually look like?

A skill is a folder containing a SKILL.md that teaches an agent a specific task or domain, plus any scripts or reference material it needs. Anthropic says the pattern came out of building Claude Code: the model handled general knowledge work well but lacked the procedural knowledge real business tasks demand. After the October 2025 launch, developers published thousands of skills on GitHub within weeks and wrote loaders for Codex, Cursor and OpenCode.

What is the AAIF?

The Agentic AI Foundation is an entity under the Linux Foundation that Anthropic co-founded with Block and OpenAI last year. Anthropic had already donated the Model Context Protocol there, and Agent Skills now follows the same path. Maintenance runs through individuals rather than companies: engineers from Anthropic, Google, OpenAI and elsewhere take part as people, not as vendor representatives.

Can I still use it without joining the foundation?

Yes. Anthropic states plainly that you can keep using the standard, or contribute to it, without joining the AAIF. The specification lives at agentskills.io, discussion happens on GitHub, and there is a Discord for feedback on proposed specification changes.

What matters most for people who actually use skills?

Security. A neutral standard makes skills easier to move between platforms, which also means you will install skills written by strangers — and a skill can ship executable scripts. The proposed roadmap puts security guidance for skill authors and installers near the front, so until that lands, treat every skill as software that needs review before it runs inside an agent with real access.
