Anthropic's Agent Skills standard governance transfer

Anthropic has transferred the Agent Skills open standard to the Agentic AI Foundation (AAIF), which operates under the Linux Foundation. The standard, published in December 2025, defines a format where each skill is a folder containing a SKILL.md instruction file plus optional scripts and reference files that agents load on demand. It originated from work on Claude Code, where developers needed a way to give agents procedural knowledge for real business tasks. The standard has since been adopted by over 70 platforms including ChatGPT, Cursor, GitHub Copilot, and VS Code, with one million skills published and nearly 280 million installed. Anthropic's donation covers the Agent Skills name, logo, GitHub organization, and agentskills.io domain. David Soria Parra and Mahesh Murag are named as Lead Maintainers, with engineers from Anthropic, Google, OpenAI, and others maintaining the standard going forward.
