Individual skill
astro
Use when building a content-driven or marketing site with Astro 6: static-first pages, islands and partial hydration, content collections, server islands, per-route on-demand rendering, deploy adapters, and Astro 5→6 migration. NOT app-router React with server actions and heavy client interactivity (that is `nextjs`).

# Astro 6 — static-first sites, islands, content collections
## The prime directive
**Ship zero client JavaScript by default. Hydrate the smallest possible surface, as late as you can
get away with.** An `.astro` component renders to HTML at build time and ships *no* runtime; every
island is a bundle the visitor downloads, parses, and executes. Content and marketing sites win on
TTFB/LCP and Lighthouse, not on React-everywhere. If you find yourself adding `client:load` to make
a page "work," stop — the page already works; you are adding interactivity, and interactivity is the
expensive exception, not the default.
