What problem does it solve? Auditing website speed page by page with PageSpeed Insights is slow and misses patterns. This Skill runs Unlighthouse to crawl an entire site and execute Lighthouse on every unique route, then groups results by page template so you fix the slow container once instead of each URL. ## Core Features & Use Cases - Full-site performance scan: Crawls the site via sitemap/robots and runs Lighthouse on every route, producing average performance, accessibility, best-practices, and SEO scores. - Core Web Vitals diagnostics: Reports lab LCP, CLS, TBT, FCP, and Speed Index, flags pages failing Google's good thresholds, and lists the 10 slowest pages. - Actionable issue list: Aggregates every failing Lighthouse audit with severity, pages affected, and estimated savings, ordered by impact. - Use Case: A site owner says "my site loads slowly and CWV are in the red." Run the script against the domain, identify that the Article template averages LCP 4.8s due to an unoptimized hero image, and get a prioritized fix list rendered in a local dashboard. ## Quick Start Ask the assistant to analyze the performance of your entire website at https://example.com with Unlighthouse and show the slowest templates and Core Web Vitals.
