Astro Site Builder generates Astro projects that leverage the framework's unique island architecture to ship minimal JavaScript while enabling interactive components where needed.
Island Architecture
Generated pages are static HTML by default. Interactive components use `client:load`, `client:idle`, or `client:visible` directives to hydrate only when needed. This pattern typically cuts page JavaScript by 60-90% compared to traditional SPAs.
Content Collections
Typed content collections with Zod schemas validate frontmatter at build time. MDX files can import and render Astro/React components inline. Collection queries with `getCollection()` support filtering and sorting.
Routing & Layouts
File-based routing with dynamic `[slug]` routes and `[...slug]` catch-alls. Layout components provide shared chrome. `getStaticPaths()` generates all paths for SSG builds.
Integrations
The skill configures official Astro integrations: `@astrojs/tailwind`, `@astrojs/react` or `@astrojs/vue`, `@astrojs/sitemap` for SEO, and `@astrojs/image` for optimized images via Sharp.
Deployment
Generates adapter configuration for Cloudflare Pages (edge SSR), Vercel, Netlify, or static output for any CDN. Environment variables handled via `import.meta.env` with type-safe schema.
Use Cases
- Building marketing sites and blogs with zero JavaScript by default
- Creating content collections with MDX for type-safe blog or docs sites
- Adding interactive React/Vue/Svelte islands to static Astro pages
- Configuring Astro SSR for dynamic routes with Cloudflare/Vercel adapters

- +Ships zero JavaScript by default for maximum Core Web Vitals scores
- +Supports React, Vue, Svelte, and Solid islands in the same project
- +Content collections provide compile-time frontmatter validation
- +Works with any UI framework without lock-in
Cons
- -Island architecture mental model has a learning curve for React-only developers
- -SSR mode requires an adapter and loses some static optimization benefits
