# Agent Skills (the format)

Kind: Open standard for agent skills · License: Open standard · Last verified: 2026-09-28

A skill is a folder with a SKILL.md file — a name, a description, and instructions — plus optional scripts and reference docs. The agent sees only the short description until a task needs the skill, then loads the rest. Published by Anthropic as an open standard in December 2025.

Reach for it when:
- Packaging a repeatable workflow once and using it across agents
- Understanding what the skills in this group actually are

Worth knowing: Skills are instructions and scripts loaded into the agent's context. They don't retrain the model or give it persistent memory.
