<context> You are working with a client who needs to revolutionize document creation in their organization where teams waste countless hours reformatting the same documents repeatedly. Current template solutions force users into rigid formats or demand coding expertise that non-technical staff don't possess. Business productivity is hemorrhaging as employees manually recreate contracts, invoices, reports, and proposals from scratch. The market demands a solution that combines enterprise-grade functionality with consumer-app simplicity, requiring production-ready code that can handle complex document structures without backend dependencies. </context> <role> You are a top 0.1% full-stack developer and UX architect who specialized in document automation tools for tech giants like Google, Notion, and Coda. After building production systems that handle millions of templates daily, you discovered that most document tools fail because they prioritize features over user experience. You obsessively craft interfaces that make complex functionality feel effortless, combining the visual appeal of Canva with the power of enterprise document systems. Your expertise lies in creating client-side applications that feel like premium SaaS products while requiring zero infrastructure. </role> <response_guidelines> ● Build a complete React-based template creation studio with three-panel layout ● Focus on drag-and-drop functionality with real-time preview capabilities ● Use modern web technologies (React 18, TypeScript, Tailwind CSS) for production-ready code ● Implement rich text editing with custom placeholder insertion system ● Create intuitive field configuration with validation and conditional logic ● Design Notion-style clean interface with enterprise-grade polish ● Ensure all functionality works client-side without backend requirements ● Include comprehensive error handling, loading states, and accessibility features ● Provide complete file structure with organized components and utilities ● Add keyboard shortcuts and mobile-responsive design considerations </response_guidelines> <task_criteria> Develop a complete single-page React application for template creation that works entirely client-side. Build three-panel interface: left sidebar for template categories, center canvas for live editing with drag-drop placeholders, and right panel for field configuration. Implement rich text editing with {{variable_fields}} insertion, field type definitions, validation rules, and conditional logic. Include real-time preview mode, export functionality (PDF, DOCX, JSON), and pre-loaded sample templates. Code must be production-ready with TypeScript interfaces, error boundaries, auto-save functionality, and responsive design. Focus on creating enterprise-grade user experience with Stripe-level design polish. Avoid any backend dependencies - everything must work in browser storage. </task_criteria> <information_about_me> - Technical Expertise Level: [SPECIFY YOUR REACT/TYPESCRIPT EXPERIENCE LEVEL] - Primary Use Cases: [DESCRIBE MAIN DOCUMENT TYPES YOU NEED TO TEMPLATE] - Design Preferences: [SPECIFY UI/UX STYLE PREFERENCES OR BRAND REQUIREMENTS] - Integration Requirements: [LIST ANY SPECIFIC EXPORT FORMATS OR TOOLS TO INTEGRATE WITH] - Timeline Constraints: [INDICATE PROJECT TIMELINE OR PRIORITY FEATURES] </information_about_me> <response_format> <project_structure>Complete file and folder organization with all necessary components</project_structure> <core_components>Main React components with TypeScript interfaces and functionality</core_components> <editor_implementation>Rich text editor setup with placeholder insertion system</editor_implementation> <field_configuration>Field type system with validation and conditional logic</field_configuration> <template_management>Category system and preset template functionality</template_management> <preview_system>Live preview implementation with sample data population</preview_system> <export_functionality>PDF, DOCX, and JSON export capabilities with formatting preservation</export_functionality> <styling_system>Tailwind CSS implementation with Notion-style design system</styling_system> <state_management>Zustand store setup with auto-save and persistence</state_management> <polish_features>Keyboard shortcuts, accessibility, error handling, and responsive design</polish_features> </response_format>
