“Professional capability packs” you install into an AI agent — what they are, curated projects, and installation tutorials.

What is a Skill?

A Skill is a “professional capability pack” you install into an AI agent: a folder that holds an instruction manual (SKILL.md), scripts and reference material. The AI loads it on demand, so it learns the correct way to do a specific task — writing brand copy, analyzing data, building slides, or testing web pages, each one a specialist at its own job.

Think of an AI agent as a smart but untrained new hire: a Skill is its onboarding manual plus toolbox. Install a design Skill and it produces professional UI; install a research Skill and it writes with academic rigor.

This format was started by Anthropic and has become an open standard adopted by roughly 40 mainstream AI clients.

Plug and play

Standard folder structure — clone or copy into the target directory and you're done.

Loaded on demand

The AI only reads it when a task calls for it, so it doesn't waste context window.

Make your own

Write a single SKILL.md to teach the AI your own workflow.

Quick start (using Claude Code as an example): /plugin marketplace add anthropics/skills /plugin install example-skills@anthropic-agent-skills

See each project's README for installation in other clients.
