Build content-focused websites with Astro — zero JS by default, islands architecture, multi-framework components, and Markdown/MDX support.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Astro Web Framework
## Overview
Astro is a web framework designed for content-rich websites — blogs, docs, portfolios, marketing sites, and e-commerce. Its core innovation is the **Islands Architecture**: by default, Astro ships zero JavaScript to the browser. Interactive components are selectively hydrated as isolated "islands." Astro supports React, Vue, Svelte, Solid, and other UI frameworks simultaneously in the same project, letting you pick the right tool per component.
## When to Use This Skill
- Use when building a blog, documentation site, marketing page, or portfolio
- Use when performance and Core Web Vitals are the top priority
- Use when the project is content-heavy with Markdown or MDX files
- Use when you want SSG (static) output with optional SSR for dynamic routes
- Use when the user asks about `.astro` files, `Astro.props`, content collections, or `client:` directives
## How It Works
### Step 1: Project Setup
```bash
npm create astro@latest my-site
cd my-site
npm install
npm run dev
```
Add integrations as needed:
```bash
npx astro add tailwind # Tailwind CSS
npx astro add react # React component support
…
The line at the top of this page pins the label git:20260708.a07936c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
