Design System Checker

About this plugin

See exactly which libraries power your file.

Library Usage Inspector analyzes your document (or selection) and shows which published libraries are being used — and which components come from each one.

Perfect for design system teams, migrations, and large-scale audits.

⸻

What it does

• Scans all instances in the file or selection

• Detects remote components

• Groups components by library source

• Shows which components are used

• Displays usage count for each component

⸻

Why it matters

In complex files, components often come from multiple libraries.

Manually tracking them is slow and error-prone.

⸻

Use cases

— Design system audits

— Migration to a new library

— Identifying outdated components

— Pre-release cleanup

— DesignOps workflows

— Enterprise projects with multiple libraries

BIG UPDATE (20.02.2026)

Design System Health

We’ve introduced a new Design System Health section that evaluates how well your file follows system rules.

You now get:

• Local components count

• Deprecated components detection

• Custom (overridden) instances detection

• Components that require update

• Detached components

• Hidden layers

All metrics are visualized and summarized in a single integrity card.

🎨 Improved Token Analysis

Color, typography and spacing analysis have been improved.

Now the plugin:

• Distinguishes between styles, variables and raw values

• Detects unlinked values

• Shows usage count per token

• Groups values clearly for cleanup

This makes it easier to remove inconsistencies.

⸻

📐 Auto Layout & Spacing Analysis

Spacing analysis now supports:

• Gap detection

• Individual padding detection (top / right / bottom / left)

• Variable binding recognition

• Quick rebinding to tokens

⸻

⚡ Performance Improvements

• Batch processing for large files

• Variable and style caching

• Progressive scanning with loading feedback

The plugin handles complex files more smoothly.

⸻

🧠 Better Structure & UI

• Multi-section interface (Color, Text, Spacing, DS Check)

• Real-time progress indicators

• Improved filtering

• Language switch support

• Refined UI transitions
