# Skills Overview

> Install, create, and attach reusable skills

**Skills** are reusable capabilities you install or create, then attach to a specific **assistant** or **agent**. Each assistant and each agent has its own skill list. Nothing you attach to an assistant is used by an agent, and the reverse is also true.

Open **Skills** from the product. You can:

* [Install](/skills/install) a skill from the marketplace
* [Create](/skills/create) a skill with instructions
* [Upload](/skills/upload) a `skill.md` or `.zip` package

Then assign skills when you [create an assistant](/guides/assistants) or [create an agent](/guides/agents). See [Assistants](/guides/assistants_overview) and [Agents](/guides/agents_overview) for an overview of each.
