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
