astro build and deployment

When reviewing or writing code, apply these guidelines:

Build and Deployment

• Optimize the build process using Astro's build command.
• Implement proper environment variable handling for different environments.
• Use static hosting platforms compatible with Astro (Netlify, Vercel, etc.).
• Implement proper CI/CD pipelines for automated builds and deployments.

astro component development

When reviewing or writing code, apply these guidelines:

Component Development

• Create .astro files for Astro components.
• Use framework-specific components (React, Vue, Svelte) when necessary.
• Implement proper component composition and reusability.
• Use Astro's component props for data passing.
• Leverage Astro's built-in components like when appropriate.

astro content management

When reviewing or writing code, apply these guidelines:

Content Management

• Use Markdown (.md) or MDX (.mdx) files for content-heavy pages.
• Leverage Astro's built-in support for frontmatter in Markdown files.
• Implement content collections for organized content management.

astro data fetching

When reviewing or writing code, apply these guidelines:

Data Fetching

• Use Astro.props for passing data to components.
• Implement getStaticPaths() for fetching data at build time.
• Use Astro.glob() for working with local files efficiently.
• Implement proper error handling for data fetching operations.

astro development guidelines

When reviewing or writing code, apply these guidelines:

• Enforce strict TypeScript settings, ensuring type safety across the project.
• Use TailwindCSS for all styling, keeping the utility-first approach in mind.
• Ensure Astro components are modular, reusable, and maintain a clear separation of concerns.

Iron Laws

1. ALWAYS use Astro components for static content; reserve framework components for interactive islands — shipping React/Vue/Svelte for non-interactive content bloats JS bundles; Astro compiles to zero JS by default. 2. ALWAYS use Content Collections with Zod schemas for typed content — defineCollection() + schema validation catches frontmatter errors at build time, not at runtime in production. 3. ALWAYS specify island hydration directives explicitly — use client:load, client:idle, or client:visible intentionally; never rely on defaults; wrong hydration strategy defeats Astro's performance model. 4. NEVER bypass Astro's built-in image optimization — always use <Image> or getImage() from astro:assets; raw <img> tags skip width/height inference, format conversion, and LCP optimization. 5. NEVER use `Astro.glob()` for typed content — it returns untyped data; use Content Collections API (getCollection(), getEntry()) for all structured content to get full TypeScript support.

Anti-Patterns

Memory Protocol (MANDATORY)

Before starting:

cat .claude/context/memory/learnings.md

After completing: Record any new patterns or exceptions discovered.

ASSUME INTERRUPTION: Your context may reset. If it's not in memory, it didn't happen.
