You are an expert in TypeScript, React, and Material UI.

Code Style and Structure

Write concise, technical TypeScript code with accurate examples.
Use functional and declarative programming patterns; avoid classes.
Prefer iteration and modularization over code duplication.
Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
Structure files: exported component, subcomponents, helpers, static content, types.
Importing React from "react" is unnecessary and should be avoided.

Naming Conventions

Use PascalCase for component names.
Use camelCase for function and variable names.
Use ALL_CAPS for constants.

TypeScript Usage

Use TypeScript for all code; prefer interfaces over types.
Avoid enums; use const objects instead.
Use functional components with TypeScript interfaces for props.

Syntax and Formatting

Use arrow functions for component definitions and callbacks.
Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements.
Use declarative JSX.

UI and Styling

Use Material UI components and icons for all UI elements.
Utilize Material UI's styling solutions (e.g., styled, makeStyles, or sx prop) for custom styling.
Implement responsive design using Material UI's responsive utilities.
When creating custom UI components, use styled-components for styling.

Material UI Usage

Import Material UI components from @mui/material.
Import Material UI icons from @mui/icons-material.
Use Material UI's theming system for consistent styling.

Performance Optimization

Use React.memo() for pure functional components when necessary.
Utilize useMemo and useCallback hooks to optimize performance.
Implement code splitting for large applications.

Debugging and Troubleshooting

After 1-2 iterations of debugging, if progress seems slow, suggest implementing debug output.
Create a reusable debug component to display network requests and props/state values.
Include a "copy to clipboard" button with the debug output for easy sharing.
Place the debug component alongside the relevant UI components being debugged.

State Management

Use React hooks (useState, useEffect, useContext) for state management.
For complex state, consider using useReducer or a state management library compatible with Material UI.

Data Storage

For local storage, use the localStorage API.
For web/cloud storage, use Firestore.
Create a separate file (e.g., firebaseConfig.ts) for Firestore configuration and import it where needed.

Follow Material UI and React best practices for component composition and prop usage.
