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.

Roughly a year after its October 2025 launch, Anthropic counts more than 70 adopting platforms, 1M published skills and nearly 280M installs.

Anthropic made the same move with MCP last year: build a standard that rival AI products adopt, then hand it to the Agentic AI Foundation
