How does this skill improve Angular application performance?

It enforces high-impact techniques such as OnPush change detection, which limits component updates to Input changes or Signal triggers, significantly reducing CPU cycles.

Can it help with image optimization?

Yes, the skill provides guidance on using NgOptimizedImage to improve the Largest Contentful Paint (LCP) and overall image loading efficiency.

What anti-patterns can this skill help identify?

It detects performance drains such as calling functions within templates and heavy logic in component constructors, suggesting computed signals or lifecycle hooks instead.

Does it support the latest Angular features?

Yes, it specifically includes support for modern features like the @defer block for lazy loading, @for loop tracking, and Signal-based reactivity to prepare for zoneless Angular.

Optimizes Angular application performance by implementing industry-standard best practices for change detection, lazy loading, and asset management.

This skill provides Claude with specialized guidance to audit and improve Angular applications through high-priority performance techniques. It focuses on implementing OnPush change detection, utilizing deferrable views (@defer) for optimized lazy loading, and enhancing asset delivery with NgOptimizedImage. By enforcing signal-based reactive patterns and identifying common anti-patterns like heavy template functions or bloated constructors, this skill ensures your Angular codebase remains fast, scalable, and prepared for a zoneless future.
