---name: breakdown-feature-implementationdescription: 'Prompt for creating detailed feature implementation plans, following Epoch monorepo structure.'--- # Feature Implementation Plan Prompt ## Goal Act as an industry-veteran software engineer responsible for crafting high-touch features for large-scale SaaS companies. Excel at creating detailed technical implementation plans for features based on a Feature PRD.Review the provided context and output a thorough, comprehensive implementation plan.**Note:** Do NOT write code in output unless it's pseudocode for technical situations. ## Output Format The output should be a complete implementation plan in Markdown format, saved to `/docs/ways-of-work/plan/{epic-name}/{feature-name}/implementation-plan.md`. ### File System Folder and file structure for both front-end and back-end repositories following Epoch's monorepo structure: ```apps/  [app-name]/services/  [service-name]/packages/  [package-name]/``` ### Implementation Plan For each feature: #### Goal Feature goal described (3-5 sentences) #### Requirements - Detailed feature requirements (bulleted list)- Implementation plan specifics #### Technical Considerations ##### System Architecture Overview Create a comprehensive system architecture diagram using Mermaid that shows how this feature integrates into the overall system. The diagram should include: - **Frontend Layer**: User interface components, state management, and client-side logic- **API Layer**: tRPC endpoints, authentication middleware, input validation, and request routing- **Business Logic Layer**: Service classes, business rules, workflow orchestration, and event handling- **Data Layer**: Database interactions, caching mechanisms, and external API integrations- **Infrastructure Layer**: Docker containers, background services, and deployment components Use subgraphs to organize these layers clearly. Show the data flow between layers with labeled arrows indicating request/response patterns, data transformations, and event flows. Include any feature-specific components, services, or data structures that are unique to this implementation. - **Technology Stack Selection**: Document choice rationale for each layer``` - **Technology Stack Selection**: Document choice rationale for each layer- **Integration Points**: Define clear boundaries and communication protocols- **Deployment Architecture**: Docker containerization strategy- **Scalability Considerations**: Horizontal and vertical scaling approaches ##### Database Schema Design Create an entity-relationship diagram using Mermaid showing the feature's data model: - **Table Specifications**: Detailed field definitions with types and constraints- **Indexing Strategy**: Performance-critical indexes and their rationale- **Foreign Key Relationships**: Data integrity and referential constraints- **Database Migration Strategy**: Version control and deployment approach ##### API Design - Endpoints with full specifications- Request/response formats with TypeScript types- Authentication and authorization with Stack Auth- Error handling strategies and status codes- Rate limiting and caching strategies ##### Frontend Architecture ###### Component Hierarchy Documentation The component structure will leverage the `shadcn/ui` library for a consistent and accessible foundation. **Layout Structure:** ```Recipe Library Page├── Header Section (shadcn: Card)│   ├── Title (shadcn: Typography `h1`)│   ├── Add Recipe Button (shadcn: Button with DropdownMenu)│   │   ├── Manual Entry (DropdownMenuItem)│   │   ├── Import from URL (DropdownMenuItem)│   │   └── Import from PDF (DropdownMenuItem)│   └── Search Input (shadcn: Input with icon)├── Main Content Area (flex container)│   ├── Filter Sidebar (aside)│   │   ├── Filter Title (shadcn: Typography `h4`)│   │   ├── Category Filters (shadcn: Checkbox group)│   │   ├── Cuisine Filters (shadcn: Checkbox group)│   │   └── Difficulty Filters (shadcn: RadioGroup)│   └── Recipe Grid (main)│       └── Recipe Card (shadcn: Card)│           ├── Recipe Image (img)│           ├── Recipe Title (shadcn: Typography `h3`)│           ├── Recipe Tags (shadcn: Badge)│           └── Quick Actions (shadcn: Button - View, Edit)``` - **State Flow Diagram**: Component state management using Mermaid- Reusable component library specifications- State management patterns with Zustand/React Query- TypeScript interfaces and types ##### Security Performance - Authentication/authorization requirements- Data validation and sanitization- Performance optimization strategies- Caching mechanisms ## Context Template - **Feature PRD:** [The content of the Feature PRD markdown file]
