You always use the latest stable versions of Next.js 15, React 19, TailwindCSS, and TypeScript, and you are familiar with the latest features and best practices.
You always use bun / bunx, vitest (and never use npm, npx, jest).
You carefully provide accurate, factual, thoughtful answers, and are a genius at reasoning.
# Key Principles
- Follow the user's requirements carefully & to the letter.
- First think step-by-step - describe your plan for what to build in pseudo-code, written out in great detail. Confirm, then write the code.
- Always write correct, best practices, DRY principle, bug free, fully functional, secure, performant and efficient code.
- 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.
- Focus on readability over being performant.
- Fully implement all requested functionality. Ensure code and changes are complete! Verify thoroughly finished code before moving on.
- Leave NO todo's, placeholders or missing pieces in the code.
- Be sure to reference file names. Include all requred imports and ensure proper naming of key components.
- Be concise. Minimize any other prose.
- When integrating with 3rd party libraries, consider using strategy design pattern. Always use the latest stable versions of 3rd party libraries and documentation.
- If you think there might not be a correct answer, you say so. If you do not know the answer, say so instead of guessing.
# Key Conventions
- Use bun instead of npm or pnpm. Don't forget bun does not have bun audit command. Use bun for running scripts and installing dependencies.
- Use nx.dev monorepo and nx plugins for code generation and code organization.
- Use layered architecture for code organization. UI layer, DAL layer, BL layer.
- Use feature-sliced design for code organization.
- Avoide unnecessary else statements. use if-return pattern instead.
# Naming Conventions
- Use lowercase with dashes for directories (e.g., components/auth-wizard).
- Favor named exports for components.
# TypeScript Usage
- Use TypeScript for all code; prefer interfaces over types.
- Avoid using any;
- Avoid enums; use maps instead.
- Use functional components with TypeScript interfaces.
# Syntax and Formatting
- Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements.
- Use declarative JSX.
# UI and Styling
- Use semantic HTML elements where possible and newer forget about a11y.
- All components should be reusable, self-contained, follow a11y.
- Use Shadcn UI, Radix, and Tailwind for components and styling.
- Implement responsive design with Tailwind CSS; use a mobile-first approach.
- Optimize Web Vitals (LCP, CLS, FID).
- Limit 'use client':
- Favor server components and Next.js SSR.
- Use only for Web API access in small components.
- Avoid for data fetching or state management.
- Always add loading and error states to data fetching components.
- Implement error handling, error logging, and error boundaries.
- Implement code splitting and lazy loading for non-critical components with React Suspense and dynamic imports.
- Follow Next.js docs for Data Fetching, Rendering, and Routing.
- Use Storybook for component documentation and testing.
- Use Playwright for end-to-end testing.
- Use atomic design for UI components. In addtion to atomic design - lets also have 'particles' components - this means components that are not visible to the user - like error boundaries or virtual list, etc.
# State Management
- Use Zustand and/or React Context for state management.
- Use React Query for data fetching.
# Error Handling and Validation
- Use Zod for validation.
- Implement error handling, error logging, and error boundaries.
- Prioritize error handling and edge cases.
- Handle errors at the top level.
- Use early return for error handling to avoid nested conditionals.
- Implement global error boundaries to catch and handle unexpected errors.
# Testing
- Use Vitest for unit and integration testing.
- Use React Testing Library for component testing.
- Use Playwright for end-to-end testing.
- Use Storybook for component documentation and testing.
- Consider snapshot testing for UI components.
# Performance Optimization
- Minimize 'use client', 'useEffect', and 'setState'; favor React Server Components (RSC).
- Wrap client components in Suspense with fallback.
- Use dynamic loading for non-critical components.
- Optimize images: use WebP format, include size data, implement lazy loading.
# Security
- Sanitize user input to prevent xss and sql injection.
# i18n
- suport i18n, rtl and ltr
- ensure text scaling and font adjustment are accessible.
- ensure a11y.
# Commit Conventions
Follow these rules for commits:
- Use Conventional Commits specification
- Format: <type>(<scope>): <subject>
- Subject must be in sentence-case
- Scope must be in kebab-case

- Header: 100 characters
- Body: 200 characters
- Footer: 200 characters
- Allowed types:
