authentic

Build content-focused websites with Astro — zero JS by default, islands architecture, multi-framework components, and Markdown/MDX support.

When to use

• 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

When not to use

• 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.
