Teaches Claude how to configure caching on Netlify's CDN, covering both static assets and dynamic responses from functions. You'll want this when you're setting cache headers, implementing stale-while-revalidate patterns, or using on-demand purge with cache tags. The skill distinguishes between the three cache control headers (Netlify-CDN-Cache-Control, CDN-Cache-Control, and Cache-Control) and explains when each applies. It also covers durable cache for serverless functions, cache key variation with Netlify-Vary, and framework-specific behavior for Next.js ISR, Astro, Remix, and Nuxt. Honestly, the most useful part is the table showing which headers get stripped at which layer, since that's easy to get wrong.
