Agent Skills

Agent skills are plain .md files + other bundled files that provide Agents with additional capabilities and context.

Developed by Anthropic but now an open standard.

A skill is just a markdown file with a little frontmatter — a name and a description of when to use it — followed by the instructions the agent reads once the skill triggers:

---
name: my-skill
description: When to reach for this skill, in one line.
---

# My Skill

The steps the agent should follow once this skill is loaded.

https://agentskills.io/specification for the specification.

https://www.skills.sh/ has become the de-facto skills directory.

These are the Agent skills I use.
