# Inspecting DOM Changes

Use this skill when the important output is a before-and-after diff rather than a single page snapshot.

## Quick start

- Capture named snapshots with `snapshot_dom`
- Compare them with `dom_diff`
- Use `list_dom_snapshots` when you need to inspect what has been saved

## Use this skill for

- verifying that a click or form submission changed the page
- diffing content before and after client-side rendering
- keeping a compact record of structural UI changes
