Major AI Skills

What are AI agent skills?

AI agent skills (also called agentic skills, Claude Code skills, Cursor skills, or SKILL.md playbooks) are reusable instruction packages for coding agents.

One-sentence answer: A skill is a folder with a required SKILL.md file (name + description + instructions) that an agent loads when the task matches.

Folder shape

skills/my-skill/
  SKILL.md      # required
  scripts/      # optional
  gpt.md        # optional model variant (Major AI Skills)

How agents use them

Discover skills by name/description
Load full SKILL.md when relevant
Or invoke explicitly (@skill-id in Cursor)
