Does this skill improve my server response times?

No, this skill focuses on perceived performance—the sensory experience of the user—rather than backend engineering or network optimization.

When should I use optimistic UI patterns?

Optimistic UI is best for low-risk, reversible actions like 'liking' a post or toggling a setting where server rejection is rare and speed is critical for flow.

What artifacts does this skill generate?

It generates HTML specimens showing side-by-side comparisons of states (Before/Loading/After) and timing specification tables for implementation.

What is a loading performance critique?

It is a structured review process that focuses on how an application handles the 'wait' period, using design patterns to make the interface feel faster and keep users informed.

Evaluates and designs perceived performance patterns, loading states, and transitions to enhance user experience during data fetching.

The Loading & Perceived Performance Critique skill empowers Claude to act as a senior UX designer specializing in the 'fragile' moments of user interaction. It analyzes application screens to identify async operations and recommends specific patterns—such as skeleton screens, optimistic UI, and progress indicators—based on expected duration tiers. By generating structured HTML wireframes and transition storyboards, it allows teams to visualize and iterate on how a product feels to the user, ensuring transparency and trust even during high-latency events.
