Skills: Simple Folders for Specializing Claude Without Custom Agents
By
–
At their core, Skills are simple. They're just a folder with a http://
SKILL.md file. The file starts with a name and description, then contains instructions, code, and resources. This simplicity means anyone can now specialize Claude without building custom agents. -
