## What it does

The skill covers {@attach}, {@html}, {@render}, {@const}, and {@debug}, along with keyed {@each} blocks and global event handling. An attachment can connect a DOM element to an external library and run again when its dependencies change.

It comes with a compact reference and separate files containing examples for attachments and other directives. {@attach} needs Svelte 5.29 or later, so check the project version before relying on it. For converting older actions, the guide points to fromAction from svelte/attachments.

## When to use it
- connect a third-party library to a DOM element
- render an HTML string in a Svelte template
