-# Angular UI Patterns
-
-Modern UI patterns for building robust Angular applications optimized for AI agents and LLMs.
-
-## Overview
-
-This skill covers essential UI patterns for:
-
-- **Loading States** - Skeleton vs spinner decision trees
-- **Error Handling** - Error boundary hierarchy and recovery
-- **Progressive Disclosure** - Using `@defer` for lazy rendering
-- **Data Display** - Handling empty, loading, and error states
-- **Form Patterns** - Submission states and validation feedback
-- **Dialog/Modal Patterns** - Proper dialog lifecycle management
-
-## Core Principles
-
-1. **Never show stale UI** - Only show loading when no data exists
-2. **Surface all errors** - Never silently fail
-3. **Optimistic updates** - Update UI before server confirms
-4. **Progressive disclosure** - Use `@defer` to load non-critical content
-5. **Graceful degradation** - Fallback for failed features
-
-## Structure
-
-The `SKILL.md` file includes:
-
-1. **Golden Rules** - Non-negotiable patterns to follow
-2. **Decision Trees** - When to use skeleton vs spinner
-3. **Code Examples** - Correct vs incorrect implementations
-4. **Anti-patterns** - Common mistakes to avoid
-
-## Quick Reference
-
-```html
-<!-- Angular template pattern for data states -->
-@if (error()) {
-<app-error-state [error]="error()" (retry)="load()" />
-} @else if (loading() && !data()) {
-<app-skeleton-state />
-} @else if (!data()?.length) {
-<app-empty-state message="No items found" />
-} @else {
-<app-data-display [data]="data()" />
-}
-```
