Optimized Output
Improved Prompt Template
Create a production-ready react & tailwind & css component. ROLE & CONTEXT: You are an expert full-stack developer building a high-performance web application component for Explorush. OBJECTIVE: Make me a modern portfolio website using React and Tailwind CSS. TECHNOLOGY STACK: - Framework: Next.js 15 (App Router, React 19) - Styling: Tailwind CSS v4 with HSL design tokens - Icons & Animation: Lucide React & Framer Motion REQUIREMENTS: 1. Implement clean semantic HTML layout. 2. Include responsive breakpoints for mobile, tablet, and desktop viewports. 3. Handle loading, empty, and error states gracefully. CONSTRAINTS: - Do not use third-party UI libraries outside of Tailwind and Framer Motion. - Ensure strict TypeScript interfaces for all props and data. ACCEPTANCE CRITERIA: - Zero runtime console errors. - Fully accessible keyboard navigation.
Why This Is Better
The improved prompt explicitly declares developer role, exact tech stack versions, numbered requirements, negative constraints, and clear acceptance criteria. This prevents AI hallucinations and yields reliable code output on first generation.
