HTTP Cache Audit

Your Lighthouse score says "Serve static assets with an efficient cache policy." You have Cache-Control: no-store on your 2MB vendor.js because you copied an API middleware header.

This skill fetches response headers for your URLs, classifies each resource's caching behavior, identifies what should be cached but isn't, and generates the exact config lines for nginx/Apache/Cloudflare/Next.js.

Works against any URL via curl. Zero external API.
