# Skill Activation

> Enable skills in the Playground.

Toggle installed skills on/off in the Playground sidebar. Active skills inject their system prompt extensions and tool definitions into the pipeline.

## How It Works

1. Open the **Skills** panel in the Playground sidebar
2. Your installed skills are listed with toggle switches
3. **Enable** a skill to include it in the next completion
4. **Disable** a skill to exclude it (without uninstalling)

Active skills are visible in the `meta` event during streaming, so you can see exactly which skills contributed to each response.

## Installing New Skills

You can browse and install new skills from the marketplace directly within the Playground:

1. Click **Browse Marketplace** in the Skills panel
2. Search or filter by category
3. Click **Install** to add a skill
4. The skill becomes immediately available for activation

## Per-Request vs. Installed

* **Installed skills** (toggled on) are active on every request from the Playground
* Use the `skills` parameter in the API to activate skills on a per-request basis without installing them
