Agent Skills now belong to an open foundation

Claim

The Agent Skills standard now sits with the Agentic AI Foundation (AAIF, Linux Foundation) next to MCP and AGENTS.md. This answers the open question in [[2026-10-skills-agents-md-convergence]] and makes the line "Agent Skills and ACP remain vendor-stewarded" in [[2026-10-acp-a2a-agui-aaif-governance]] out of date for Skills.

Evidence

• 2026-10-22, Anthropic: "We are donating the Agent Skills name and logo, the GitHub organization, and the agentskills.io domain."
• 2026-10-22: "with David Soria Parra and Mahesh Murag as Lead Maintainers."
• 2026-10-22: "We've proposed starting with a roadmap covering versioned releases, a formal proposal process, and security guidance for people who write and install skills."
• 2026-10-22: "More than 70 agent platforms, including ChatGPT, Cursor, GitHub Copilot, and VS Code, have integrated Agent Skills" and "So far, 1 million skills have been published and nearly 280 million installed." Both counts are Anthropic's own and not independently checked.
• 2026-10-22: "You can continue to use the standard or contribute to it without joining the AAIF."
• Willison (secondary) notes he predicted this in December; his page was not needed for any claim above.

Open questions

• Date of the first versioned release; whether the .claude/skills and .agents/skills directory split is resolved.
• What the security guidance says about allowed-tools.
