The skill is based on Angular Material v21.x (v21.2.0-next.2), generated at 2026-01-31.

Angular Material is the official UI component library for Angular, implementing Material Design 3 (M3). It provides a comprehensive set of pre-built, accessible components along with the Component Dev Kit (CDK) for building custom components.

When to Apply

Use this skill when:

Using Angular Material components (buttons, forms, dialogs, tables, etc.)
Theming with Material Design 3 (M3) color palettes, typography, density
Working with mat-form-field, inputs, select, autocomplete, or datepicker
Implementing data tables with sorting, pagination, and filtering
Creating dialogs, bottom sheets, snackbars, or tooltips
Building navigation with sidenav, menus, tabs, or steppers
Using CDK primitives (overlay, portal, drag-drop, virtual scrolling)
Implementing accessible components with CDK a11y utilities
Creating custom form field controls that integrate with mat-form-field
Using component test harnesses for reliable testing
Scaffolding components with Angular Material schematics

Do NOT use this skill when:

Using a different UI library (PrimeNG, ngx-bootstrap, etc.)
Building completely custom UI without Material Design
Working with Angular Aria headless primitives (use the angular-aria skill instead)
