View on GitHubWhat This Skill Does
Runs a web quality audit across performance, accessibility, SEO, and best practices based on Google Lighthouse checks. Categorizes findings by severity and returns specific code-level fixes for each issue.
Covers 150+ Lighthouse checks in one pass and returns prioritized fixes with file references, instead of running separate tools for performance, a11y, and SEO and reconciling reports by hand.
