# astro

A skill that teaches your agent the Astro web framework: pages, components, SSR adapters, content collections and deployment. Useful once a project is on Astro.

## What it does

The skill hands the agent a reference for Astro: where the config file lives, which CLI commands exist, how the project tree is laid out. It includes a config options table, sample `astro.config.ts`, a page and a component example, and a step-by-step adapter deploy.

Adapters go in with commands like `npx astro add vercel --yes`; `node`, `cloudflare` and `netlify` work the same way. After you add or change plugins, the reference tells you to re-run `npx astro sync`, otherwise the generated TypeScript types for Astro modules go stale. Run `npx astro check` before `npx astro build` — it catches type and config errors earlier.

\`src/pages` is required; without it no routes get built. Folders like `src/components` and `src/layouts` are conventions, not rules. The skill points back to `docs.astro.build` for code examples and the latest API, so check the source when you move to a newer framework version.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add astrolicious/agent-skills --skill astro -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/astro/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/astro/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add astrolicious/agent-skills --skill astro -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/astro/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add astrolicious/agent-skills --skill astro -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/astro/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install astrolicious/agent-skills astro
```

2. **Manually: put the files in place**
- File: `.github/skills/astro/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add astrolicious/agent-skills --skill astro -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/astrolicious/agent-skills --path skills/astro
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/astro/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add astrolicious/agent-skills --skill astro -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/astrolicious/agent-skills/tree/HEAD/skills/astro/SKILL.md

## When to use it
- scaffold a page and a component in an Astro project
- wire up an SSR adapter for Vercel, Netlify, Cloudflare or Node
- set up content collections and module types
- make sense of the Astro project directory layout
- build a static site and verify it before deploying

## Example prompts
- add the vercel adapter to my Astro project and walk me through the deploy steps
- create `src/pages/about.astro` with a heading and some text
- why does `npx astro check` fail on types after I install a plugin?

description: Skill for building with the Astro web framework. Helps create Astro components and pages, configure SSR adapters, set up content collections, deploy static sites, and manage project structure and CLI commands. Use when the user needs to work with Astro, mentions .astro files, asks about static site generation (SSG), islands architecture, content collections, or deploying an Astro project.

# Astro Usage Guide

**Always consult [docs.astro.build](https://docs.astro.build) for code examples and latest API.**

Astro is the web framework for content-driven websites.

---

## Quick Reference

### File Location
CLI looks for `astro.config.js`, `astro.config.mjs`, `astro.config.cjs`, and `astro.config.ts` in: `./`. Use `--config` for custom path.

### CLI Commands

- `npx astro dev` - Start the development server.
- `npx astro build` - Build your project and write it to disk.
- `npx astro check` - Check your project for errors.
- `npx astro add` - Add an integration.
- `npx astro sync` - Generate TypeScript types for all Astro modules.

**Re-run after adding/changing plugins.**

### Project Structure

Reference [project structure docs](https://docs.astro.build/en/basics/project-structure).

- `src/*` - Project source code (components, pages, styles, images, etc.)
- `src/pages` - **Required.** Defines all pages and routes.
- `src/components` - Components (convention, not required).
- `src/layouts` - Layout components (convention, not required).
- `src/styles` - CSS/Sass files (convention, not required).
- `public/*` - Non-code, unprocessed assets (fonts, icons, etc.); copied as-is to build output.
- `package.json` - Project manifest.
- `astro.config.{js,mjs,cjs,ts}` - Astro configuration file. (recommended)
- `tsconfig.json` - TypeScript configuration file. (recommended)

## Core Config Options

| Option | Notes |
|--------|-------|
| `site` | Your final, deployed URL. Used to generate sitemaps and canonical URLs. |

### Example `astro.config.ts`

```ts
import { defineConfig } from 'astro/config';

export default defineConfig({
  site: 'https://example.com',
});
```

---

## Common Workflows

### Creating a Basic Page

Add a file to `src/pages/` — the filename becomes the route:

```astro
---
// src/pages/index.astro
const title = 'Hello, Astro!';
---
<html>
  <head><title>{title}</title></head>
  <body>
    <h1>{title}</h1>
  </body>
</html>
```

### Creating a Component

```astro
---
// src/components/Card.astro
const { title, body } = Astro.props;
---
<div class="card">
  <h2>{title}</h2>
  <p>{body}</p>
</div>
```

### Deploying with an Adapter

1. Add the adapter: `npx astro add vercel --yes` (or `node`, `cloudflare`, `netlify`)
2. Run `npx astro check` to catch type and configuration errors before building.
