Astro Knowledge

astro-knowledge Skill

Expert documentation and API reference provider for Astro and Starlight development.

Purpose

The astro-knowledge skill provides on-demand documentation lookup and API verification. It helps agents confirm current syntax, check feature availability, and access comprehensive API references.

Capabilities

• API Verification: Confirm current syntax for Astro/Starlight APIs
• Feature Lookup: Check availability and usage patterns
• Documentation Search: Find relevant docs quickly
• Best Practices: Provide current recommendations
• Version Checking: Note version-specific features

Loading Strategy

This skill loads on-demand when agents need:

• API syntax confirmation
• Feature availability verification
• Documentation references
• Configuration examples
• Migration guidance

Usage

This skill is loaded when:

• Using the /lookup command for quick API reference
• During implementation via /dev for API verification
• When planning with /design for feature availability checks
• Whenever current syntax or API documentation is needed

Documentation Resources

Cached References

Location: \${CLAUDE_PLUGIN_ROOT}/skills/astro-knowledge/references/

• Full Astro API reference
• Starlight configuration guide
• Content Collections API
• Routing patterns

Knowledge Base

Location: \${CLAUDE_PLUGIN_ROOT}/knowledge-base/

• Syntax details
• Common patterns
• Best practices

MCP Server Integration

If astro-docs MCP server is available:

• Real-time documentation lookups
• Latest API information
• Version-specific documentation

Common Lookups

Collections API

```typescript // getCollection, getEntry, getEntries import { getCollection, getEntry } from 'astro:content';

// Get all entries const posts = await getCollection('blog');

// Get single entry const post = await getEntry('blog', 'post-slug');

// Filter entries const published = await getCollection('blog', ({ data }) => data.draft !== true ); ```

Dynamic Routes

```typescript // getStaticPaths return format export async function getStaticPaths() { const entries = await getCollection('docs');

return entries.map(entry => ({ params: { slug: entry.slug }, props: { entry } })); } ```

Client Directives

```astro

Starlight Config

```javascript import { defineConfig } from 'astro/config'; import starlight from '@astrojs/starlight';

export default defineConfig({ integrations: [ starlight({ title: 'My Docs', social: { github: 'https://github.com/user/repo', }, sidebar: [ { label: 'Guides', items: [ { label: 'Getting Started', link: '/guides/getting-started/' }, ], }, ], }) ] }); ```

Search Strategy

1. Identify Section: Determine relevant docs area
2. Check Cache: Look in cached references first
3. MCP Fallback: Use MCP server if available
4. Provide Context: Include examples and links

Output Format

When providing documentation:
