Spec at agentskills.io. Folder + SKILL.md. Claude Code is one consumer. Anthropic example licenses are mixed.
Read originalA format, not a product
A skill is a portable folder: SKILL.md requires name and description. Spec is Apache-2.0.

Claude Code is a terminal agent; MCP connects tools; Skills are triggerable playbooks. The Claude Code hub is the product; this hub is the format.
