## Core Principles:
  - Optimize for Hydrogens **streaming and caching** model to enhance performance.
  - Use **Shopifys Storefront API** effectively, following best practices for queries and mutations.
  - Ensure all components are **server-first** but leverage **client-side hydration** where needed.
  - Use **Tailwind CSS** efficiently with Hydrogens best practices for styling.
  - Prioritize **authentication and session handling** for Shopify customers.

## Routing & Layout in Remix
  - Use `loader` functions for **server-side data fetching**.
  - Prefer **nested routes** for modular page structures.
  - Use `useLoaderData()` instead of client-side fetching where possible.
  - Optimize Remixs **deferred loading** to improve perceived performance.

## Shopify Storefront API Usage
  - Always fetch data using **GraphQL queries** in `loader` functions.
  - Minimize API requests by batching queries efficiently.
  - Cache queries where appropriate to **reduce unnecessary API calls**.
  - Avoid over-fetching request **only the necessary fields**.
  - Use Shopifys **recommended pagination techniques** (`cursor`-based pagination).

## Hydrogen & Performance Optimizations
  - Utilize **Hydrogens streaming API** to improve time-to-first-byte (TTFB).
  - Use `CacheNone()` or `CacheLong()` selectively to control caching behavior.
  - Edge caching Ensure frequently accessed data is cached at the CDN level.
  - Prefer `useShopQuery()` over manual API calls for **consistent data fetching**.
  - Offload **expensive computations to server-side** where possible.

## Styling & Tailwind CSS
  - Use **Hydrogens built-in Tailwind setup** for consistency.
  - Avoid excessive utility classes by leveraging **Tailwinds theme and variants**.
  - Structure styles efficiently to **minimize CSS bloat**.
  - Use **Tailwinds responsive utilities** to ensure a mobile-first approach.

## Authentication & Session Handling
  - Implement Shopifys **customer authentication** using `customerAccessToken`.
  - Store authentication tokens securely in **server-side sessions**.
  - Use Remix loaders and actions to **handle login and logout server-side**.
  - Ensure **session expiry is handled gracefully** to prevent errors.
  - Implement **SSR-friendly authentication checks** to avoid hydration mismatches.

## Deployment on Shopify Oxygen
  - Follow **Shopifys guidelines for edge deployment**.
  - Ensure **Remix server handlers** are optimized for Oxygen.
  - Use `@shopify/hydrogen` utilities for **seamless integration with Shopify's infrastructure**.
  - Test deployments using Shopifys **Oxygen preview environment** before production.

## Component & Code Best Practices
  - Prefer **server components** whenever possible to reduce client-side JavaScript.
  - Use **lazy loading** (`React.lazy()`, `Suspense`) for non-critical UI components.
  - Keep components **small, modular, and reusable**.
  - Avoid excessive **client-side state management**; leverage Remix loaders instead.
  - Use **React Error Boundaries** for graceful error handling.

## Key Conventions:
  - Always **fetch data in loaders**; minimize client-side API calls.
  - Structure routes **to take full advantage of Remixs nested routing**.
  - Use **server caching strategies** to reduce redundant Storefront API calls.
  - Optimize **Hydrogens streaming features** for a fast user experience.
  - Follow **Shopifys best practices for deployment on Oxygen**.

# Flutter App Expert rules

### Pacing and Scope Control
1. **Explicit Checkpoint Requirements**
   - You must pause after completing each logical unit of work and wait for explicit approval before continuing.
   - Never implement more than one task in a single session without confirmation.

2. **Minimalist Implementation Rule**
   - Always implement the absolute minimum to meet the specified task requirements.
   - When in doubt about scope, choose the narrower interpretation.

3. **Staged Development Protocol**
   - Follow a strict 'propose → approve → implement → review' cycle for every change.
   - After implementing each component, stop and provide a clear summary of what was changed and what remains to be done.

4. **Scope Boundary Enforcement**
   - If a task appears to require changes outside the initially identified files or components, pause and request explicit permission.
   - Never perform 'while I'm at it' improvements without prior approval.

### Communications
1. **Mandatory Checkpoints**
   - After every change, pause and summarize what you've done and what you're planning next.
   - Mark each implemented feature as [COMPLETE] and ask if you should continue to the next item.

2. **Complexity Warning System**
   - If implementation requires touching more than 3 files, flag this as [COMPLEX CHANGE] and wait for confirmation.
   - Proactively identify potential ripple effects before implementing any change.

3. **Change Magnitude Indicators**
   - Classify all proposed changes as [MINOR] (1-5 lines), [MODERATE] (5-20 lines), or [MAJOR] (20+ lines).
   - For [MAJOR] changes, provide a detailed implementation plan and wait for explicit approval.

4. **Testability Focus**
   - Every implementation must pause at the earliest point where testing is possible.
   - Never proceed past a testable checkpoint without confirmation that the current implementation works.
