Lighthouse-md turns speed audits into action. One click runs Google Lighthouse on your storefront and translates every failing audit into Shopify terms: theme, images, app embeds. Ask Sidekick why your store is slow and get answers from your own data. Export the fixes as a CLAUDE.md file that Claude Code applies to your theme while you review and publish. Nothing changes on your store until you approve. Re-audit to verify the win with trend charts and history.

• Mobile Lighthouse audit: Performance, Accessibility, Best Practices, SEO
• Core Web Vitals with change-vs-previous deltas
• Sidekick integration: conversational answers from your latest audit
