Anthropic has now given ownership of its Agent Skills (a standard recipe-card format that any AI agent, including ChatGPT and GitHub Copilot, can read to learn a task.)to the Agentic AI Foundation, a neutral group run under the Linux Foundation.
In Agent Skills, each skill is a folder holding a SKILL.md instruction file plus any scripts or reference files an agent loads on demand.
Agent Skills began as a fix for Claude Code’s missing procedural knowledge and now runs inside rival products such as ChatGPT, GitHub Copilot, Cursor and VS Code.

Since December 2025, 70+ agent platforms have integrated the standard, including ChatGPT, Cursor, GitHub Copilot, and VS Code.
