Astro Web Framework workflow skill. Use this skill when the user needs Build content-focused websites with Astro — zero JS by default, islands architecture, multi-framework components, and Markdown/MDX support and the operator should preserve the upstream workflow, copied support files, and provenance before merging or handing off.
This public intake copy packages plugins/antigravity-awesome-skills-claude/skills/astro from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.
Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.
This intake keeps the copied upstream files intact and uses the external_source block in metadata.json plus ORIGIN.md as the provenance anchor for review.
Astro Web Framework
Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: How It Works, Security & Safety Notes, Common Pitfalls, Limitations.
When to Use This Skill
Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.
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
Use when the request clearly matches the imported source intent: Build content-focused websites with Astro — zero JS by default, islands architecture, multi-framework components, and Markdown/MDX support.

Workflow
This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.
Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
Read the overview and provenance files before loading any copied upstream support files.
Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.
Execute the upstream workflow while keeping provenance and source boundaries explicit in the working notes.
Validate the result against the upstream expectations and the evidence you can point to in the copied files.
Escalate or hand off to a related skill when the work moves out of this imported workflow's center of gravity.
Before merge or closure, record what was used, what changed, and what the reviewer still needs to verify.
Imported Workflow Notes
Imported: 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.
Imported: How It Works
Step 1: Project Setup
npm create astro@latest my-site
cd my-site
npm install
npm run dev
Add integrations as needed:
npx astro add tailwind # Tailwind CSS
npx astro add react # React component support
npx astro add mdx # MDX support
npx astro add sitemap # Auto sitemap.xml
npx astro add vercel # Vercel SSR adapter
By default, UI framework components render to static HTML with no JS. Use client: directives to hydrate:
---
import Counter from '../components/Counter.tsx'; // React component
import VideoPlayer from '../components/VideoPlayer.svelte';
---
<!-- Static HTML — no JavaScript sent to browser -->
<Counter initialCount={0} />
<!-- Hydrate immediately on page load -->
<Counter initialCount={0} client:load />
<!-- Hydrate when the component scrolls into view -->
<VideoPlayer src="/demo.mp4" client:visible />
<!-- Hydrate only when browser is idle -->
<Analytics client:idle />
<!-- Hydrate only on a specific media query -->
<MobileMenu client:media="(max-width: 768px)" />
Opt individual pages into SSR with export const prerender = false.
Examples
Example 1: Ask for the upstream workflow directly
Use @astro to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.
Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.
Example 2: Ask for a provenance-grounded review
Review @astro against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.
Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.
Example 3: Narrow the copied support files before execution
Use @astro for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.
Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.
Example 4: Build a reviewer packet
Review @astro using the copied upstream files plus provenance, then summarize any gaps before merge.
Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.
---
import SearchBox from '../components/SearchBox.tsx';
---
<!-- Hydrated immediately — this island is interactive -->
<SearchBox client:load />
Best Practices
Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.
✅ Keep most components as static .astro files — only hydrate what must be interactive
✅ Use content collections for all Markdown/MDX content — you get type safety and auto-validation
✅ Prefer client:visible over client:load for below-the-fold components to reduce initial JS
✅ Use import.meta.env for environment variables — prefix public vars with PUBLIC_
✅ Add from astro:transitions for smooth page navigation without a full SPA
❌ Don't use client:load on every component — this defeats Astro's performance advantage
❌ Don't put secrets in .astro frontmatter that gets used in client-facing templates

Troubleshooting
Problem: The operator skipped the imported context and answered too generically
Symptoms: The result ignores the upstream workflow in plugins/antigravity-awesome-skills-claude/skills/astro, fails to mention provenance, or does not use any copied source files at all.
Solution: Re-open metadata.json, ORIGIN.md, and the most relevant copied upstream files. Check the external_source block first, then restate the provenance before continuing.
Problem: The imported workflow feels incomplete during review
Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task.
Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.
Problem: The task drifted into a different specialization
Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better.
Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

Imported Reference Notes
Imported: Security & Safety Notes
Frontmatter code in .astro files runs server-side only and is never exposed to the browser.
Use import.meta.env.PUBLIC_* only for non-sensitive values. Private env vars (no PUBLIC_ prefix) are never sent to the client.
When using SSR mode, validate all Astro.request inputs before database queries or API calls.
Sanitize any user-supplied content before rendering with set:html — it bypasses auto-escaping.
Imported: Common Pitfalls
Problem: JavaScript from a React/Vue component doesn't run in the browser
Solution: Add a client: directive (client:load, client:visible, etc.) — without it, components render as static HTML only.
Problem:getStaticPaths data is stale after content updates during dev
Solution: Astro's dev server watches content files — restart if changes to content/config.ts are not reflected.
Problem:Astro.props type is any — no autocomplete
Solution: Define a Props interface or type in the frontmatter and Astro will infer it automatically.
Problem: CSS from a .astro component bleeds into other components
Solution: Styles in .astro<style> tags are automatically scoped. Use :global() only when intentionally targeting children.
Imported: Limitations
Use this skill only when the task clearly matches the scope described above.
Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
