# Skill registries

> **Note:** The Agent Builder is part of the Mastra Enterprise Edition. Production deployments require a valid EE license. [Contact sales](https://mastra.ai/contact) for more information.

Registries let the Agent Builder browse and install community skills directly from the UI. All registries are opt-in. When no registry is enabled, the Builder hides registry browse UI entirely.

## Quickstart

Enable the [skills.sh](https://skills.sh) registry:

```typescript
import { MastraEditor } from '@mastra/editor'

new MastraEditor({
  builder: {
    enabled: true,
    registries: {
      skillsSh: { enabled: true },
    },
  },
})
```

The Builder library tab now exposes a **Browse** view backed by skills.sh. End users can preview a skill, then install it into an agent.

> **Note:** See the [AgentBuilderOptions reference](https://mastra.ai/reference/editor/agent-builder/agent-builder-options) for the full `registries` schema.
