📖 What Are Agent Skills?

Agent Skills are folders containing a SKILL.md file with instructions and metadata that teach Claude how to perform specialized tasks. Skills follow the open Agent Skills Standard by Anthropic.

Without Skill:  Generic AI → Average output
With Skill:     Expert Python Developer → Production-grade code ✨

Skill Format

Each skill is a folder with a SKILL.md file:
